LCD Panel Type

The display screen can be divided into three types: normal temperature, wide temperature and ultra-wide temperature according to the supported working temperature range. The normal temperature display supports the working temperature between 0 °C and 50 °C, and the wide temperature display supports the working temperature between -20 °C and +70 °C. ℃, the ultra-wide temperature display supports the working temperature between -40℃~+90℃. Usually, the display screen with good low temperature performance will have poor high temperature performance. The wider the operating temperature range, the higher the price. Users can choose suitable display products according to actual use conditions.

About the resolution of LCD

Resolution Resolution is a very important performance indicator. It refers to the number of points that can be displayed horizontally and vertically on the screen (lines and planes on the screen are composed of points). The higher the resolution, the more information can be included in the same screen. 480×800 resolution and 320×240 resolution are perfect display. Because there is little difference between the two, but the maximum resolution is not necessarily the most appropriate resolution. If 480×8000 LCD is used in 320×240 LCD, the display content will be smaller.   Visual area of LCD It refers to the part of the display area that can be used to display the image in practical application. The full size is actually the size of its frame and PCB board, and the part that can be used to display images does not reach this size at all, because the frame takes up some space. Generally speaking, the area of 4-inch 480×800 LCD is 51.84×86.4mm, and that of 3.5-inch 320×240 LCD is 70.08×52.56mm. But for LCD, the size of area is basically the size of the visible area, and the space occupied by the frame is relatively small. The 4-inch 480×800 LCD has a display area of 51.84 * 86.4mm.So choose LCD screen, choose suitable for your own equipment.   Reaction speed The unit of time used to measure reaction speed is millisecond (ms), which is the time required for a pixel to go from light to dark and from dark to light.

When customers use LCD, what should they pay attention to?

The following are the precautions for LCD module operation:   If the display screen is damaged and the internal LCD leaks, do not let it enter the mouth. If it gets on clothes or skin, wash it quickly with soap and water. In order to reduce static electricity, do not carry out assembly and other work in dry environment. The LCD module has a film to protect the display screen. Be careful when removing this protective film as it may generate static electricity. The display screen is made of glass. Do not apply mechanical impact, such as falling from height. It must be grounded correctly. Minimize electrode corrosion. Water droplets, moisture condensation or current in high temperature environment may accelerate electrode corrosion. At low temperature, liquid crystal solidification will lead to directional defects or bubbles. When the liquid crystal module is subject to strong vibration at low temperature, bubbles will also be generated. If the LCD module works for a long time and displays the same pattern, the pattern will remain on the screen like a phantom, and there will be subtle contrast differences. If you want to regain the normal working state, you can temporarily stop using it for a while. It is worth noting that this phenomenon will not have an adverse effect on the reliability of the performance.
