The viewing angle range of the LCD screen refers to the angle at which customers observe the content displayed on the LCD screen from different directions.
Watching beyond a certain range will cause color distortion or ghosting.
The viewing angle of the monochrome LCD screen is usually 3, 6, 9 and 12 points. At present, the monochrome LCD screens are mostly used at 6 and 12 points, that is, looking up at 6 points and looking down at 12 points. Calculated by angle, there is an optimal visual angle at 6 o'clock or 12 o'clock. For example, the common TN LCD screen, although the viewing angle is not particularly good, but it is cheaper, more suitable for many occasions.
The viewing angle range of the LCD screen of the following materials:
TN: 30 degrees; HTN: 45 degrees; STN: 60 degrees to 90 degrees; FSTN: 90 degrees to 120 degrees;
The display effect of the LCD screen is related to the viewing angle and contrast. The display effect of the LCD screen is related to the viewing angle and contrast.
The display effect of the LCD screen is also related to the contrast.
For any LCD display, the display effect is always the first! The realism, softness and saturation of the display effect display, bringing users the most intuitive visual experience! As for why the contrast and viewing angle are attributed to the display effect, the contrast is a gradual level of the LCD screen from dark to light. The greater the ratio, the more gradation levels from dark to light, and 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 voltage, the batch of polarizers, the temperature change and the different shade changes caused by the backlight batch, the display effect will also be deviated. , Customers need to fine-tune the voltage to achieve the desired display effect. It is not possible to adjust the contrast outside the COG, it is adjusted through software. When the customer selects the model, it is necessary to communicate the pros and cons to the customer. If you want to solve this phenomenon more effectively, it is recommended that the customer 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, etc.) The correlation between contrast and viewing angle is related to the overall application site and visual effects of the client.
