There are many kinds of parameter settings for the LCD display, but do you know what effect these parameters have?
1. Dot pitch and resolution ratio
The principle of the liquid crystal display determines that its best resolution is its fixed resolution. The dot pitch of the liquid crystal display of the same level is also fixed, and the dot pitch of the liquid crystal display is exactly the same at any point of the full screen.
2. Brightness
Generally, the brightness is indicated in the specifications of liquid crystal displays, and the indication of brightness is the maximum brightness that the backlight light source can produce, which is different from the brightness unit “Candle Lux” of ordinary light bulbs. The unit used by LCD monitors is cd/m2, and general LCD monitors have the ability to display 200cd/m2 brightness. Now the mainstream even reaches 300cd/m2 or above, and its function lies in the coordination of suitable working environment light. If the light in the operating environment is brighter, the LCD display will be more unclear if the brightness of the LCD display is not adjusted a little higher, so the larger the maximum brightness, the larger the environmental range can be adapted.
3. Contrast ratio
When choosing a monitor, users should also pay attention to the contrast and brightness of the LCD monitor. That is: the higher of the contrast, the more distinct between the white and black output. The higher the brightness, the clearer the image can be displayed in a lighter environment. Moreover, in different operating environment light, proper adjustment of the contrast value will help the picture display clear, high-contrast and high-brightness displays are too light, easy to make eyes tired. Therefore, users must adjust the brightness and contrast to appropriate levels when using LCD monitors.
4. Viewing direction
The viewing angle of a liquid crystal display includes two indicators, a horizontal viewing angle and a vertical viewing angle. The horizontal viewing angle is expressed by the vertical normal of the display (that is, the vertical imaginary line in the middle of the display). The displayed image can still be seen normally at a certain angle to the left or right perpendicular to the normal. This angle range is the horizontal viewing angle of the liquid crystal display. Also if the horizontal normal is the standard, the vertical viewing angle is called It is the vertical viewing angle.
