4K smart TV purchasing power survey

According to the current consumer awareness of 4K TV, we randomly distributed 100 questionnaires from Weibo WeChat and various methods. We conducted some surveys on some issues that consumers are concerned about. I believe this can also be done. What is the level of consumer acceptance of this type of television product?


From this survey, it can be found that consumers are still placing the most importance on 4K image quality. 40% of consumers pay special attention to this aspect of television. In addition, product appearance and functional operation are also particularly concerned.


In the 4K purchase demand survey, it can be seen that today's 4K TV consumers have a strong desire to buy, nearly 90% of the respondents said they will consider buying a TV in the recent purchase Taiwan 4K TV.


As the workmanship and the 4K image quality require cost input in many aspects, the price we set is limited to more than 4,000, which is more in line with the actual situation and the acceptable range.

We will enable radiation testers and temperature testers to conduct comprehensive testing. On the chip source, we will use Sony's 4K player and mobile hard disk storage for intuitive testing. In addition, we will use dedicated security Bunny to run. The sub-software and test quality SPYDER kits test important parameters such as the color gamut of the TV screen.

Radiation testers, temperature testers, and so on are the three common methods we use to test these basic safety and quality issues of television. Although TVs have undergone various rigorous tests before they are released, it is still necessary for consumers to recognize them. Whether it will be harmful to humans in terms of safe use, and whether it can bring direct feedback on energy conservation and environmental protection.

The use of Blu-ray players and mobile hard disk are mainly to provide huge data support in film source playback and various video picture playback.

4K Smart TV Appreciation

TCL L49E6700A-UD



The fuselage of TCL L49E6700A-UD adopts all-metal material design. At first glance, it feels very atmospheric, domineering leakage, brand new all panel screen, and the four-dimensional narrow edge design makes the whole look very exquisite and beautiful. The use of aluminum-magnesium alloy to create an overall, the entire machine smoothly placed on the desktop, reflecting a very good sense of beauty, combined with the bottom of the iconic TCL diamond-shaped LOGO, highlighting extraordinary temperament.

Skyworth 55G8200



Skyworth 55G8200 is a GLED geek Internet TV released in September 2014. It is a flagship model of Skyworth in 2014. The 55-inch LG Display 4 color 4K screen body is equipped with a wide color gamut technology. The proportion is very high. Apart from the screen base, the base part of the frame has adopted a very distinguished local gold color scheme, which is very much in line with the aesthetics of today. The base of the G8200 adopts the “Taurus” style, which makes it very high and the home environment. It is also very harmonious, and it can change direction and stand firm on the desktop.

Hisense LED55XT900X3DU



Hisense LED55XT900X3DU's overall appearance is very consistent with the style of modern home, tough and without losing beauty, local gold color just right, do not feel any tired, see people love to see the design of flowers with a narrow border highlight design sense, extremely craftsmanship Superb, in terms of the base, this Hisense's ULED masterpiece uses a brilliant color scheme that runs through the TV. The design of the flower shape is very elegant, and the same all-metal feel is superb.

Konka LED50X8800U



Konka LED50X8800U size is 50 inches, is now the most sought after in the home market size, product design by the professionals to create the ultimate luxury, local color gold is also a lot of consumers to comply with the aesthetic point of view, plus this year Konka chose Fan Bingbing as her new spokesperson for the Queen's temperament, making Konka's Slim series of television products of great concern. The base also used the local gold scrub process, and the dark lines in the middle of the base also reflect the manufacturer's design. With great care, it is excellent both in industrial design and open mold.

Cool open glory A55



This cool open glory A55 walk is a simple line of science and technology, so from the appearance point of view is a strong minimalist style, combined with 55-inch screen and 3840x2160 ultra-high resolution, making this A55 can reach 4K standard The overall feeling does not lose the atmosphere. The frame of the A55 TV uses a silver metal edging. The design of the ultra-narrow frame makes the screen's viewing area more extendable. This technology has been used many times before the cool TV was turned on. Metal elements Joining can effectively increase the overall texture of the TV, and the body's firmness is also enhanced. The base of the A55 is also a simple process. Polished metal grinding makes it perfectly integrated with the TV host.

Domestic flagship 4K smart TV frame size

If there is no ultra-narrow edge design in 2014, then there will be only the elimination of this market. In addition to the overall visual need to present the most beautiful state, the materials used in the frame and the degree of strength are also the same for each consumer. The issues of concern, after all, the details of the true knowledge, from these subtle areas can really test whether the manufacturers can truly be responsible to consumers.

Konka LED50X8800U ultra-narrow side

Cool open glory A55 ultra narrow side

From this set of data, Konka's Slim1 generation took the lead in arranging the width of the border to 7.8mm in August of this year. Afterwards, the cool-cooled glorious A55 also reached this figure. There is competition to be motivated and in the new products that follow. Skyworth's G8200 has achieved a 5.9mm ultra-narrow frame. In fact, from the perspective of the ultra-narrow frame of the mobile phone, people are very fond of such ultra-thin and thin, and thin is good, but if it is not done very well Thin actually does not have to rely on itself, like the iPhone generation and then generation, ultra-narrow design has not yet appeared, but good design still depends on the whole, ultra-narrow frame alone is not enough to explain everything, then look See if these 4K flagships have a perfect profile.

Domestic flagship 4K smart TV body thickness

This year, no matter whether it is a foreign brand or a domestically-made model, the main ones are not thin, but in addition to the border, the thickness from the side is actually an important factor in determining whether the product is truly beautiful, regardless of the Goddess goddess, There is no doubt that the good or bad side of the face is also very important, the body thickness is too large will undoubtedly damage the television placed in the room, especially the need to wall the overall beauty, let us look at how these several domestic TV in the body thickness performance It.

TCL L49E6700A-UD



TCL L49E6700A-UD



Hisense


Konka LED50X8800U



Cool open glory A55



The body thickness of these five smart TVs is controlled to a very good level. Konka's Slim1 generation is also the LED50X8800U in our Hengping review. It has achieved a staggering 1.28cm in the thickness of the fuselage, which was released at the end of the year. The Slim 2 generation is less than 1cm. It can be seen that Konka has been at the forefront of the industry in the TV production process. In other brands, Skyworth, which belongs to the same brand, and CoolTV, have both done the thickness of the body. At the level of 17-18, the body thickness of TCL and Hisense is only from the naked eye, and there is a big gap with the previous ones. The same is not surprising, because these five 4K TVs belong to the flagship model of a brand, so they are invariably chose the metal edging, making the border shape of these five products are very texture.

Domestic flagship 4K smart TV interface settings

Someone will certainly say how the interface of the TV can represent the appearance of the product? We feel we can, of course, because the location and number of interfaces directly determine the concept of the product in design. It is like the QD color display television set released by TCL at the end of the year. The design of the socket of the backplane is directly hidden. It is also consistent. The praise, so that the arrangement of the interface is appropriate directly determines the beauty of the product after use.

TCL L49E6700A-UD




TCL L49E6700A-UD interface is divided into vertical and horizontal columns, vertical is some of the more common need to plug in and out of external devices from time to time, while the bottom is horizontal and some need to maintain long-term plug in the TV network and audio interface, this point Very human, basically will not cause any of my plug, the arrangement of space is also relatively wide, even if the blind operation, find these jacks will not feel very laborious, the only regret is that there are only two HDMI sockets, considering the future include More and more audio and game consoles will come into our lives. Obviously 3 or more are more pragmatic numbers.

TCL L49E6700A-UD


Hisense Chao



Konka LED50X8800U




Konka LED50X8800U interface is extremely rich, also take two rows of vertical and horizontal rows of sockets, three HDMI interface is a standard configuration, and the number of USB interfaces up to five, that is to say, external five storage or peripherals are Will not cause any pressure, VGA interface is also humanely preserved, and the distance between the interface and interface is more appropriate, in line with daily habits.

Cool open glory A55




Cool open glory A55 Smart TV's back interface can be said that these five TVs go single-edged sword to go the front line, cool open A55 will always bring us constant surprises, in terms of interface, only retain the HDMI and USB two interfaces, HDMI interface Used to access the wireless receiver, you can access more HDMI high-definition signal from the transmitter, you can use the HDMI to play the local video resources, to achieve the effect of multi-source playback, after a simple setting, browse the web on the TV Or you can have an extraordinarily beautiful effect by performing related document operations or viewing high-definition pictures. The USB interface can only be used to upgrade the system. To tell the truth, only two interfaces still add a lot of things that can be found.

Domestic flagship 4K smart TV cooling outlet design

Even thin LCD TVs are inevitably large due to their own power consumption. Therefore, the problem of heat dissipation is a problem that every good TV product must pay attention to. Therefore, the heat sink on the back panel is also a problem. The very important link, on the one hand, is to ensure the overall aesthetics of the TV. On the other hand, it also directly affects the service life of the TV. We also made detailed observations on the beauty of the five TVs.



The cooling holes of the TCL L49E6700A-UD are still continuation of the previous design. The large wide hexagonal mesh belt above the back panel can easily release heat, and the metal structure used on the back can also prevent the machine from overheating. The flat backboard design also looks very chic.




The Skyworth 55G8200 backplane adopts an overall infusion process, which is very smooth and flat, and the overall distribution of cooling holes on the backplane is even and reasonable. In the fuselage, the upper and lower parts of the heat can be well taken care of.



Hisense LED55XT900X3DU cooling hole design and design is always the manufacturer's inherent method, the array of strip-shaped heat sink polishing detailed, good workmanship, and in the back of the protruding area also has a row of cooling holes designed to release heat energy up and down .



The back panel of Konka LED50X8800U adopts a polished design. From the actual point of view, it feels very seductive, that is, the anti-fingerprint capability is slightly insufficient. In terms of the heat dissipation hole, the overall layout of the back panel should be able to maintain Konka's consistent level of temperature control.



The back panel of the Cool Open Glory A55 is basically a textbook model of modern minimalist aesthetics. The back panel of the all-metal panel is evenly distributed, while the top heat sink distribution design is within the same metal structure. At the same time, the Scandinavian style believes that it can also have very good cooling performance.



The back panel and heat sink design of these models can be said to have their own merits, and how to realize it, we will continue to compare the power test.

4K smart TV picture quality evaluation

For 4K TVs, if you discard the performance on the picture quality, then you are not far from the end of the day. If only a single TV is not enough to discern its color performance, then there are five flagship 4K TVs. When we are in front of our eyes, if we do not remain calm, we can easily disturb the mind with dazzling colors. Today, we can achieve very objective public answers through 4 static 4K TV test charts. In addition, we test their dynamic quality performance by playing the latest version of the Ninja Turtle Movie, and use SPYDER to derive their most accurate color gamut performance.

As the concept of high-end 4K is prevalent, a few days ago, Professor Zhang Qiankai, a member of the China Photographers Association and a renowned photographic equipment expert, has released a unique and accurate view of the color display industry. "High-end 4K test chart." The test chart is mainly tested in terms of 4K resolution, color accuracy, and wide viewing angle. By comparing test images on a 4K TV, you can easily distinguish the difference in the quality of different 4K technologies. 4K TV is the easiest to understand test chart.






Domestic flagship 4K smart TV resolution test

Prof. Qian’s 4 high-end 4K test charts. This 4K TV resolution test chart includes text, line drawings, resolution tables, and color block diagrams. 4K ultra high definition (resolution 3840×2160) and full HD (1920×1080) identification limits are indicated by red and blue arrows, respectively. Among them, the 4K in the various lines can distinguish the 1st in the finest, and the full HD can only recognize the 3rd.


The TCL L49E6700A-UD is quite effective in the 4K resolution test. In all colors, it can be visually recognized to be the first to display any color. Although TV is mainly a game function, it is in 4K. The structure of the color blocks is clear and precise, and the display on the handwriting is also very good, and the edge recognition is still guaranteed. The exclusive use of TV to enhance the quality of optical film 3M incremental increase in color saturation is indeed improved.


Skyworth 55G8200 adopts LG Display's new 4K panel, so it is said that the 4K resolution link is still very good, the performance of the color block structure is clear and natural, there is nothing to drag the water, by inserting white in the middle of R, G, B, The composition of the pixel W is currently only produced by Samsung and LG, and there is no pressure on the handwriting display, even in the marginal areas.


Hisense LED55XT900X3DU test in 4K resolution is also remarkable, due to the use of a special ULED technology, controllable backlight in the black area of ​​the word display is particularly noticeable, white text recognition ability is excellent, the outline structure of the writing without any distortion With regard to the discrimination of online bars, the first one of each color can be clearly seen. On the screen shading, it is also quite satisfying, and the color block structure is naturally detailed.


The Konka LED50X8800U's 4K resolution test is basically not too much hindrance, the recognition of the text is very high, such as the complex structure of the word, can also be seen from the TV at a glance, also in the lower line display, a variety of colors The first display is also very easy, the details of the color block structure can be easily identified, the color transition is close to the natural, the overall satisfaction.


LG Display's ultra-high definition 4K IPS hard screen has great advantages in color depth and viewing angle. In the 4K resolution test section, the A55 has a clear and precise structure in the color blocks, and it is also very good in terms of the realistic capabilities of the writing. .

Domestic flagship 4K smart TV tone level restore test

The rich tone levels, especially the light and dark levels, are important signs for displaying image grades. On the display of 4K TV tone level restoration test patterns, the bright and dark parts of the normal display should be able to be displayed on the test chart. With about 8 levels, level distribution maps and sphere diagrams should be able to show all levels.


The TCL L49E6700-UD TV's jump in the gradient area is not found. It is only in the darkest area where there is a slight degree of parallelism. This is also in an acceptable range. At the shadow level, TV performance can only be said. The law-abiding, can see its light and shade level slightly, but in the spherical chart look, the 21st order gray scale can all easily distinguish, the color transition on the gradual change chart is still relatively gentle.


The gray level transition of the Skyworth 55G8200 in the gradient area can be said to be extremely outstanding, especially in the darkest areas, where the gray-level transition can still be clearly seen. In addition, both the dark and light levels can be instantly Seeing the subtle changes in light and darkness, it is possible to view the flowers in a spherical shape with 21 shades of gray. The degree of recognition is high, and the degree of jump is also completely absent. The gradual transition of the sphere is also particularly smooth and smooth. In this piece, Skyworth's GLED shows a clear advantage.


The grey level of Hisense LED55XT900X3DU's gradient area is still basically satisfactory. In addition to the few acceptable parallels in the last darkest place, the transition in grayscale is relatively smooth and natural, without any jumping phenomenon. In the light and dark levels, the dark part can be made visible in the level, and in the two levels, there is also a good performance, and in the spherical gray and gray transition, the color transition between light and dark Smooth and natural, clearly distinguishing 21 shades of gray does not have much problem. Only in the darkest areas there are slight concurrences, and gradual transition presents the most natural transition.


From the gray-tone transition on the left, Konka LED50X8800U does not show any parallel or skipping phenomenon. LGD 4K hard screen seems to be able to maintain certain advantages at this point, and the bright and dark display at the bright level can be said It is quite obvious that the degree of vagueness is quite high, but on the right spherical 21 gray machine map, all the gray levels can be easily identified. The phenomenon of jumping and ordering does not appear, and the gradient spherical pattern is also comparable. Comfortable transition.


Contrast, for 4K TV, especially light and dark levels is one of the important standards for display effect. For cool TV with LGD 4K hard screen, we can see through the professional tone level restoration test chart. The performance of the shades in the picture still has a very good level, especially the gray-scale performance in the spherical graph is relatively natural, there is no parallel or stepped phenomenon, and the overall performance is still quite good.

Domestic flagship 4K smart TV color performance test

4K TV color performance and visual angle test chart The top 24 color blocks are selected according to the SHB color system hue angle every 15 degrees a color, saturation and brightness are taken 100%, the more saturated the color swatch, the wider the display color gamut If the color blocks have a concatenation, it means there is an error in the color reproduction.


In the HSB color system block diagram, the TCL L49E6700A-UD has a very fine congruence between 90-105 colors. Other colors are seen in the restoration and different angles of view, but in terms of color distribution. All regions basically exhibit a triangular shape. There are only slight deviations in the Y and G regions. On the chromosphere diagram, there are several blue and pink spheres that show a certain amount of ring-shaped bands. The average transition is slightly inferior. From the overall color performance, there will be a slight deviation, and the overall situation is still relatively satisfactory, with high saturation.


The color performance of the Skyworth 55G8200 is still quite amazing. In the ideal state, the color blocks of the HSB color system are saturated, and the color does not show any degree of parallelism or skipping. Viewed from other angles, There is no case of color shifting, but in the color distribution chart, you can see that the triangles in the Y and G areas have already undergone a significant deformation. On the right side of the color chart, the level of the sphere is rich. At the same time, there was no monochromatic banding mutation, the color evenly balanced transition, and it was quite good in the aspect of color expression.


Hisense LED55XT900X3DU TV is also worthy of praise in the 4K color performance, in the color distribution map reward, basically all regions can present a more natural triangle shape, color convergence naturally, and in the HSB color system color block diagram, in addition to some In light blue and light purple, there are slightly parallel steps. Other colors do well in saturation, but in the chromosphere diagram, it can be seen that there are ring-like ring-shaped mutations in individual colors. There is still a lot of room for improvement in color matching here.


Konka LED50X8800U in the 4K color performance and visual angle test chart on the three test links performance is still relatively stable and excellent, in the HSB color system color block on the way, all the colors, except in the light green has a slight degree of In addition, other colors are ideally saturated with color, and their differences can be observed with the naked eye. On the chromosphere diagram, the spheres of all colors are very natural and uniform on the transition of color, and no variation occurs. On the color distribution diagram, the color changes slightly with a triangular deviation, but in any case, the Konka LED50X8800U is in color. The display is still commendable.


Perhaps because of the different positioning, the cool and glorious A55 smart TV will still have a slight gap between the color display and Skyworth's flagship in the same size. After all, the price is also different by almost 3,000 yuan. However, the overall performance is not without highlights. On the HSB color system block diagram, you can see that there is a slight color deviation on the bright green, and the order is obvious. On the color distribution map, the space in the Y area is obviously occupied by the green color of the G area, in the color ball. On the map, the red and pink spherules show a slight ring-shaped mutation. The appearance of spheres of other colors is still normal, but the gap with the Skyworth 55G8200 is obvious.

Domestic flagship 4K smart TV landscape test

This set of test charts also includes a 4K TV test landscape, through which the images with higher requirements are displayed, and the quality of the 4K TV can be easily distinguished. Hard screen 4K measured compared with ordinary 4K, hard screen 4K brightness is low, saturation is normal, color reproduction is accurate, color scale is accurate, ordinary 4K screen brightness and saturation is high, but the light and dark levels are missing, color reproduction accuracy Poor, large viewing angles have visible color shifts.

TCL L49E6700A-UD 4K landscape test

Skyworth 55G8200 4K landscape test

Hisense LED55XT900X3DU 4K landscape test

Konka LED50X8800U 4K landscape test

Cool open glory A55 4K landscape test

From the comparison of these five charts, Skyworth 55G8200 and Konka LED50X8800U with LGD 4K hard screen are slightly insufficient in brightness on the screen, but saturation and color reproduction are still quite accurate. In addition, these three televisions In the area below the landscape, the place where people live in smoke is more vivid in the details of the smoke, mainly due to the color control, LGD can control the black to a very low level, so that the color reproduction is more accurate, and TCL L49E6700A- UD and Hisense LED55XT900X3DU are better than others in color brightness, but in terms of grasping the details, it can only be said to be quite satisfactory.

For reasons of time, the 5 4K flagship smart TVs will be introduced here by the Hengping Review. Later, more in-depth and comprehensive evaluations will be presented later.
