ADS technology is a wide-angle technology developed by LCD industry for large-size, high-definition desktop display and LCD TV applications, which is currently called hard screen technology. ADS technology overcomes the shortcoming of low light transmittance of traditional IPS(in-plane-switch) technology, and achieves high light transmittance under the premise of large viewing angle.
Compared with other civilian markets with wide horizontal viewing angles, in the LCD panel using ip or MVA, the horizontal and vertical viewing angles in the advertising panel are 178. The first two advertisements are the same as IPS panels, and they also belong to hard screen technology, that is, the screen surface is more difficult than TN and VA panels, the response time is relatively fast (black and white and 5ms), and the viewing angle is larger.
Extended data:
Hard screen is more stable than soft screen. Hard screen technology optimizes the arrangement of liquid crystal molecules. When the LCD screen encounters external pressure, its molecular structure will be slightly depressed, but the overall distribution of molecules is still horizontal. When the soft screen encounters external pressure.
The liquid crystal molecules on the soft screen are arranged vertically, and the molecular depressions are serious, showing an inverted octagon. It can be seen that the stability of hard screen molecular structure is much higher than that of soft screen molecular structure.
In terms of heat dissipation, soft screen is better than hard screen. The heat dissipation of LCD TV is mainly concentrated on the screen, but in the production process of hard screen, coating will affect the heat dissipation effect to a certain extent. Soft screen does not need backlight, so it has low heat dissipation.
After the phenomenon that the soft screen is easy to smear, the soft hand of the screen will produce a watermark, and the fast moving picture played back will have a sense of pause, which means that the photo will become a mess and the screen will have a residual image.
When watching a program with fast picture changes, the soft-screen LCD TV will appear tailing phenomenon, and the dynamic definition will decrease. Soft screen LCD TV is more suitable for watching slow-paced programs.
