No matter how you evaluate the PyeongChang Olympic Games, this session of the Olympic Winter Games have been with the torch extinguished as the past.
Let the regret stay in Pyeongchang, after all, the Winter Olympics has entered a 'Beijing time'.
Speaking of this, the closing ceremony of the Pyeongmong Olympic Winter Games Zhang Yi Mou directed the 'Beijing eight minutes', colorful lighting effects and many high-tech elements come on stage, so that the world is amazing.
One of the most eye-catching is the 'ice-screen' robot that runs through the audience. This transparent and colorful screen aroused curiosity from many people. The home TV screen is black. What about this transparent 'ice screen'? Do it?
Guess A: ice - since called 'ice screen', then of course it is made of ice! Transparent ice cubes used to make the screen just right!
Rumor: Pro ... you think about how ice display Picture it?
Guess B: ultra-short-throw projection - the robot in the bottom of the screen is actually a Projector , The screen projected onto the screen.
Rumor: robot is responsible for both walking and projection, is not too hard for it? Short-focus projection technology itself is very mature, laser TV is one of its applications, but the projection is difficult to imaging on transparent media, PASS!
Correct answer: transparent display panel.
Before we give everyone a transparent display, but 'ice screen' did not use OLED Or LCD panels, but the use of LED as a display medium.Why? A very important reason is that OLED is not bright enough, and tens of thousands of stadiums on the scene to ensure the results, then the high brightness of the LED is the best choice.
'Ice-screen' R & D team leader Huang Qingsheng said: In accordance with the requirements of the director team, a single screen size of 1.5 meters span, two screen length of 3 meters, if there is no pillar in the middle, it is difficult to stability.In addition, Long, the consistency of the color is not good, to the back of the light color is not the same .In order to participate in eight minutes show, the team conducted a special technical research, not only produced a higher specification, better technology products, but also synchronization Achieved a process upgrade.
Similar to the TV, LED transparent screen also has two types of positive and side light, from the visual angle, light uniformity, permeability and other aspects of side light has the advantage, which is the Olympic team choose the side of the reasons for the light.
In fact, although transparent LED screen is very sci-fi, but in the application level has been quite mature, not only 'Beijing 8 minutes', has many applications in many wrestling occasions.
For example, before the explosion CCTV network 'National Treasure Show' 'National Treasure' stage on the use of a transparent LED screen, users of the "National Treasure," the stage effect amazed.
The choice of another goal of transparent LED screen, of course, is for the organizers it!
We all know that LCD and O LED display The dominance of the field has long been dominated by Korean companies, and the 'transparent LED' featured in 'Beijing's 8-Minute' is entirely designed and manufactured by China.
According to Huang Qingsheng, "Currently, we are at a leading position in the world of ice-screen technology. This time we have a three-meter-long screen with no beams in between. We are the first such craft in the world at this moment."
A few days ago, Lenovo started mass production of memory using DDR4 DRAM particles, but also to break the monopoly of technology for many years. Really let people shouted: amazing, my country!
Finally, friends from all over the world are welcome, similar to Beijing in 2022!
Welcome, welcome friends!
