Two Factors Affecting The Display Effect of The LCD Screen
11.28.2023
When it comes to affecting the display of LCD screens, what do you usually think of? One seemingly unimportant but important factor is the viewing angle of the LCD display.
The viewing angle range of the LCD screen refers to the angle at which customers view the display screen content from different directions and different positions. When viewed beyond a certain range, color distortion or ghosting may occur.
The viewing angles of monochrome LCD screens are usually 3 o'clock, 6 o'clock, 9 o'clock, and 12 o'clock. At present, monochrome LCD screens are mostly used at 6 o'clock and 12 o'clock, that is, heads up at 6 o'clock, and 12 o'clock looking down. From the perspective, 6 or 12 o'clock has an optimal viewing angle. For example, the ordinary TN screen, although the perspective effect is not very good, but the advantage is that the price is cheap, it is more suitable for many occasions.
The viewing angle range of the LCD screen is as follows: TN: 30 °; HTN: 45 °; STN: 60 ° ~ 90 °; FSTN: 90 ° ~ 120 °.
In addition, LCD display effects are also related to contrast.
For any display, the display effect is always first! The realism, softness, and saturation of the display effect will bring the most intuitive visual experience to the user. As for why the contrast and viewing angle are included in the display effect, the contrast is the degree of gradient of the LCD screen from dark to light. The higher the ratio, the more gradient levels from dark to light, and therefore the richer the colors displayed.
Therefore, the display effect of the LCD screen is related to the viewing angle and contrast. At the same time, in order to avoid changes in the post-voltage, polarizer batches, temperature changes, and backlight batches, the display effect will also vary. Customers need to fine-tune the voltage to achieve the desired display effect. The contrast in COG cannot be adjusted externally, only by software. Then when the customer is selecting, he needs to communicate with the customer and feedback the advantages and disadvantages. If you want to solve this phenomenon more effectively, customers are advised to make a menu interface to adjust the contrast. This type of liquid crystal is commonly 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 customer's overall application position and visual effects.
