Няколко ключови точки за закупуване на LCD екрани:
1. Electro-optical response characteristics
The relative light transmittance of the liquid crystal display changes with the applied signal voltage, which is the electro-optical response characteristic, which is one of the most important characteristics of LCD.
LCD
2, resolution
Resolution is also called resolution, pixel degree, etc. What we see from the display is composed of pixels. In the case of the same screen size, the larger the pixels, the more delicate the displayed screen content. For example, the resolution of 19201080 means that the display screen has 1920 pixels in the horizontal direction and 1080 pixels in the vertical direction.
3, contrast
The ratio of the brightness of the bright state and the dark state of the highlighted display part under the condition of a certain external brightness, that is, the difference between the foreground and the background color.
4. Perspective
When viewing the highlight screen, the display graphics can be seen most clearly, and the angle with the best display effect (good contrast) is called the highlight viewing angle.
5. Response time
The time for the transmittance to reach 90 percent from 10 percent , that is, the time difference between when the driving signal is applied and when you see the pattern you want.
