Highlight liquid crystal display screen is widely used in display products, and it is one of the most commonly used display screens at present. Understand the basic knowledge of highlight liquid crystal display screen in order to better product selection. This paper will analyze the basic knowledge of highlight screen from the aspects of contrast, response time, and resolution, and then analyze and select the type from the aspect of product application.
1. Electro-optic response characteristics.
The relative light transmittance of LCD varies with the change of applied signal voltage, which is the characteristic of electro-optic response, which is one of the most important characteristics of LCD.
Resolution is also called resolution, pixel degree, etc., and what we see from the display screen is made up of pixels. In the case of the same screen size, the larger the pixel, the more delicate the screen content is displayed. For example, the resolution of 1920 to 1080 means that the display screen has 1920 pixels horizontally and 1080 pixels vertically.
Under the condition of a certain brightness of the outside world, the ratio of the brightness of the highlighted part to that of the dark state, that is, the difference between the foreground and the background color.
When watching the highlight screen, the angle that can see the clearest display graphics and the best display effect (good contrast) is called the highlighted angle of view.
5. Response time.
The time when the transmittance reaches 90% from 10%, that is, the time difference between applying the drive signal and seeing the figure you want.
The general LCD screen, its brightness is only about 200 nits to 300 nits, through the technology can enhance the LCD brightness to 600 nits to 3000 nits, but also can improve the line of sight, visual angle, color saturation and contrast, LCD applications from NB, display, to ATM, car TV, large-scale TV wall display, smart community, large-scale business district and so on.
