The operation precautions and storage precautions of the LCD display module

LCD display module (LCM): First, the operating Notes: 1, the display is made of glass, do not impose mechanical shock, such as falling from a high level. 2, if the display is damaged, the internal LCD leakage, do not make it into the mouth. If you get on your clothes or skin, wash it quickly with soap and water. 3. Do not apply excessive force to the connection area of the display surface or the LCD display module, as this will cause a change in color tone. 4, the LCD display module display surface of the polarizer is soft, and easy to scratch, careful operation. 5, if the LCD module display surface dirty, wipe with a soft dry cloth. If serious fouling, with isopropyl alcohol or ethanol (alcohol), dipped in wet cloth to wipe. 6, other solvents may damage the polarizer, especially water, ketones, fragrances and so on. 7, the use of mounting holes to install the LCD display module, make sure not to twist, bend and deformation. Deformation will have a significant impact on the quality of the display. 8, when installing the LCD display module, do not force pull or bend the I / O lead or backlit lead. 9, touch the LCD module TAB may lead to abnormal display, do not touch the TAB. 10, do not disassemble the LCD display module. 11, NC feet to be vacant, do not take anything. 12, if the logic circuit power off, do not enter the signal. 13, in order to prevent static damage to the components, to maintain a good working environment. 14, to avoid open circuit, be careful to heat the paper operation. 15, the edge of the glass screen sharp, careful operation. Second, the storage Notes 1, the LCD screen display module, to avoid direct exposure to sunlight or fluorescent light. The LCD display module is stored in the anti-static bag, stored at room temperature and humidity conditions. (Avoid high humidity / high temperature and low temperature below 0 ° C.) If possible, the LCD display module should be stored under conditions that are shipped from our company. A, move the module, do not fall to the ground. B, assembly tools such as soldering iron, must be properly grounded. C, in order to reduce the generation of static electricity, do not carry out in a dry environment assembly and other work. D, the LCD display module has a layer of protective film. Be careful when tearing this layer of protective film, as it may cause static electricity. 2, to minimize electrode corrosion. Water droplets, moisture condensation or high temperature environments may accelerate electrode corrosion. Third, the other 1, in the low temperature (below the storage temperature range), liquid crystal solidification will lead to directional defects or produce bubbles (black or white). Vapors also occur when the liquid crystal module is strongly vibrated at low temperatures. 2, if the LCD display module for a long time to work and display the same pattern, the pattern will be the same as the phantom retained on the screen and there will be subtle contrast. If you want to regain the normal working condition, you can temporarily stop using it for a while. It is worth noting that this phenomenon does not adversely affect the reliability of performance.
