Among the parameters of LCD panel, there is a horizontal/vertical viewing angle. The horizontal viewing angle of traditional LCD is 45 degrees, which means that the viewer has a 90-degree viewing angle. When the included angle between the user and the display is larger than the nominal angle, you will not be able to see the content on the display clearly. This is why many users reflect that games or games are running on the LCD When watching a movie, the color of the picture is distorted or gray. But the wide view technology is different, it can increase the view angle of LCD to 160 degrees or more, so as to solve the problem of insufficient view angle.
Wide-angle panels can be divided into iPS panels, MVA panel,s and PVA panels. The price is very high, but the color can reach 16.7M and the angle of view is more than 170 degrees.
1. IPS panel
Most of its high-end LCD display panel has a long response time, but it is a professional LCD panel. In addition, the viewing angle of IPS panel is very large, which can basically reach the level of CRT display, and the color display ability reaches 16.7M, but the performance in contrast, response time, black background color, and color saturation is not satisfactory.
2. MVA panel
The MVA panel is what is the earliest simultaneous interpreting technology. Its liquid crystal layer contains a convex object for liquid crystal molecules. Under the condition of no voltage, the MVA panel looks like two different kinds of traditional technology. The liquid crystal molecule is perpendicular to the screen, and once the voltage is applied, the liquid crystal molecules will be attached to the convex object to offset the vertical state of the surface of the protrusion. This technology effectively improves the response time and viewing angle of LCD, so that the viewing angle can reach more than 170 degrees. At the same time, the contrast is also greatly improved, and the color display ability can reach 16.7M. Now, this technology is also relatively mature, so the market penetration rate is relatively high.
3. PVA panel
PVA panel is a derivative of MVA panel. It uses a transparent ITO layer to replace the bumps in MVA liquid crystal molecules. In this way, the transmittance is greatly improved, the image quality is improved, and the display efficiency is greatly improved. The viewing angle can also reach 170 degrees, and the response time, contrast, and color recovery ability are greatly improved. It can be said that in addition to the price, the PVA liquid crystal panel has a good performance There are few weaknesses. Due to the high production cost, PVA panel is mostly used for LCD TV and high-end graphics LCD, which is still a little far away from ordinary consumers.
