Using special LCD graphic design and process design and matching raw materials, this product features TN high contrast and wide viewing angle of STN. The maximum contrast ratio with backlight is 200:1, and the limit size is 385*340. And the reliability can be achieved in the characteristics of earthquake resistance, low temperature and high temperature resistance, and is mainly applied to airports, parking lots, public advertisements, and the like.
Stereo glasses display [ 2019-08-23 ]
Stereo glasses are used to watch stereoscopic movies, TVs, and stereo games. The response time of the display is only a few milliseconds, and the switch is fast, reaching the speed of fast switching between the left and right eyes of the person, and forming a stereo image in the human brain.
The liquid crystal display module is a component that assembles a liquid crystal display device, a connector, an integrated circuit, a PCB circuit board, a backlight, and a structural member. The English name is “LCD Module”, referred to as “LCM”, and Chinese is generally called “LCD Module”. In fact it is a commercial part. According to the provisions of China's relevant national standards: only the non-detachable integrated components are called "modules", and the detachable is called "components". Therefore, the name of the specification should be called "liquid crystal display component". But for a long time people have become accustomed to calling it a "module."
Troubleshooting in use [ 2019-08-23 ]
When a qualified liquid crystal display device is used, it may sometimes malfunction due to unreasonable use, unsuitable conditions, unqualified accessories, or improper installation methods. The reasons and troubleshooting are as follows
Simple fault inquiry [ 2019-08-23 ]
In order to find out the fault of the liquid crystal display device during use, you can use the pointer multimeter R=10kΩ resistor to search. This is a high-resistance file, which can check various on-off and off-state conditions that affect the display, because it has The DC voltage of 9-15v can drive the display of the liquid crystal display device to judge whether the display device is normal or not from the display state. However, since the multimeter outputs a DC voltage, it is preferable not to delay the detection for a long time to avoid an electrochemical reaction. You can use the following tricks to reduce the damaging effect of DC, that is, hold a test pen in your hand, then hold the liquid crystal display back electrode with your fingers, and then use another test lead to detect the remaining segments of the electrode. The internal resistance of the external power supply is greatly increased, thereby reducing the damage of the DC component.
