From April 20, 1994, when China fully accessed the Internet, it opened a new era of Chinese Internet. In a blink of an eye, I couldn’t help but wonder where I have been in this 20-year period. In fact, it is not difficult to see from the development of the popular epoch-making digital products, the Internet has given us a lot of gifts in the past 20 years. On the occasion of the 20 years of China's Internet, let us also review what changes have taken place in the LED micro projector industry.
Increase brightness, stand firm
LED micro projectors can be said to have been born in the growth stage of the Internet. The micro-projection that was first launched has a brightness of only a few tens to a hundred lumens, and the resolution is equally small. The projection effect is not flattering, and the light is slightly brighter. Under the environment, the picture will not be clear. If it weren't because of its light weight and ultra-portable advantages, it would be difficult for the initial enterprise-level threshold to be crossed.
With the advent of the second-generation TI high-definition micro-projection chip, it is not only smaller in size, but also capable of achieving high-definition resolution, and is also more resistant to high temperatures, and can withstand higher-power bulb modules, effectively improving the brightness of the light source. After continuous improvement of technology, the measured brightness of LED micro projectors has reached 500 lumens last year, some can reach 600 lumens, and the resolution is also upgraded to 1280&TImes; 800, the application range has been expanded.
In the rapid development of the Internet era, looking at the history of LED micro-projection, the improvement of brightness and resolution is the most significant. From the first few tens of lumens to the current thousand lumens, it has been an upward trend. We believe that the brightness of LED micro-injection will be greatly improved in the future, and it has a wider range of applications.
Intelligent, technological innovation
With the development of the Internet, the built-in system of smartphones and tablets has come out, and since then, the prelude to the intelligentization of digital products has been unveiled. In the past, the so-called micro-investment system was very simple and only supported the display of related functions. Since 2013, LED micro projectors equipped with intelligent operating systems have begun to appear, marking the dawn of an intelligent era of micro-investment.
At present, the micro-injection built-in intelligent system is mainly based on Android, and there are also very few micro-projections built-in Windows 7 system. The micro-projection equipped with intelligent system can directly download the Android mobile client application, which makes the use of the pico projector wider and more convenient, and enhances the user experience. In today's intelligent application, the intelligent system built into the LED micro projector can be a successful and bold attempt.
From the application point of view, smart micro-investment fully has the functions of smart mobile devices such as smart phones and tablet computers. In addition, the projector itself can project large-size images in a short distance, and it is even more powerful. It is easy to watch videos, TV shows, variety shows, Internet TV and other video programs of various popular video sites online. No need to connect to computer, notebook and other signal sources, a micro projector with intelligent operating system can easily meet the entertainment needs of users.
Wireless function, the trend of the times
With the continuous development of wireless network transmission technology, wireless connection function is the trend of the times, not only micro-projectors, digital products including notebook computers, smart phones, tablet computers, ultrabooks, etc., all have wireless connectivity.
At present, the wireless connection methods adopted by the micro-investment are mainly divided into two types: a built-in wireless module and an external wireless module. The built-in wireless module can directly connect to the network through the menu operation. The external connection method only needs to insert the wireless module into the USB interface to perform wireless connection. The smart micro-projection generally adopts a built-in method.
The micro-projection wireless can also be used as an AP hotspot to realize point-to-point connection of devices such as smart phones and tablet computers, and share images and videos in the mobile phone anytime and anywhere through the projector.
Although the micro projector is in the boom stage of the Internet era, its own development speed is still praiseworthy, and the continuous breakthrough of brightness makes it a place in the projector market. The emergence of built-in intelligent system micro-investment has broadened its application areas and improved the user experience. With wireless connectivity, it is even more icing on the cake.
