When it comes to affecting the display effect of LCD screens, what do you usually think of? One of the seemingly unimportant but important factors is the perspective of the lcd display.
The viewing angle range of lcd screens refers to the angle that customers observe the content on the screen from different directions and positions. When watching beyond a certain range, it will produce color distortion or ghost phenomenon.
The viewing angle of monochrome LCD screens is usually 3 o'clock, 6 o'clock, 9 o'clock and 12:00. At present, monochromatic LCD screens are mostly used at 6 o'clock and 12:00, that is, look up at 6 o'clock and look down at 12:00. In terms of angle, there is an optimal visual angle at 6 o'clock or 12:00. For example, the common TN screen, although the perspective is not very good, but the advantage is that the price is cheap, many occasions are more suitable.
The viewing angle range of the LCD screens of the following materials: TN:30°; HTN:45°; STN:60°to 90°; FSTN:90°to 120°.
In addition, the display effect of LCDs is also related to the contrast.
For any display screen, the display effect is always the first! The realism, softness and saturation of the display effect will give users the most intuitive visual experience. As for why the contrast and viewing angle are classified into the display effect, the contrast is a gradual change level of the liquid crystal display screen from deep to shallow. The higher the ratio, the more levels of gradient from deep to shallow, thus the richer the color display.
Therefore, the display effect of the LCD screen is related to the viewing angle and contrast. At the same time, in order to avoid the later changes in voltage, polarizer batches, temperature changes and backlight batches, the display effect will also be deviated. Customers are required to fine-tune the voltage to achieve the ideal display effect. The contrast cannot be adjusted externally in COG, it is adjusted by software. Well, when the customer chooses the type, he needs to communicate and feedback the advantages and disadvantages to the customer. If you want to solve this phenomenon more effectively, suggest the customer to make a menu interface to adjust the contrast. This type of liquid crystal is usually used in a wide range of applications. Instrumentation, medical, aerospace, high-speed rail, and so on. ).
The correlation between contrast and viewing angle is related to the overall application location and visual effects of the client.
