On the afternoon of the 2nd, in the second floor exhibition hall of Zhengzhou International Convention and Exhibition Center, there was plenty of light and no window blocking. The reporter felt the charm of this stereo screen and found that enough light had little effect on the image effect.
In this regard, Professor Li Chao, member of the Stereo Professional Committee of the China Image and Graphics Society and president of Zhongyuan Display Technology Co., Ltd. said that at present, the stereoscopic technology of the domestic cinema system has many limitations. In comparison, the LED stereo screen uses a network-specific cable connection. The brightness of the indoor LED screen is more than 15 times that of the cinema projection system, and the contrast is equivalent to more than 100 times that of the projection system. It is not affected much; the specially designed outdoor type can be viewed normally during the daytime. 
The first "LED Stereo Movie Broadcasting System" developed by Zhengzhou Zhongyuan Display Technology Co., Ltd. was unveiled at the Zhengzhou International Convention and Exhibition Center. It is understood that this is the world's first "LED stereo movie broadcasting system".
