What problems should be paid attention to when using LCD module? Let's take a look together.</p><p><br></p><p>1. Avoid applying DC voltage. Long-term application of excessive DC components will cause the electrolysis and electrodes to age easily, thereby reducing the service life of the LCD screen.</p><p><br></p><p>2. Prevent ultraviolet rays from irradiating the screen. Liquid crystals and polarizers are organic substances, and chemical reactions and deterioration will occur under ultraviolet light. Long-term direct sunlight should also be avoided during the use of the LCD screen.</p><p><br></p><p>3. Harmful gases should be prevented from corroding the liquid crystal display accessories, and harmful gas isolation measures should be taken. After the entire machine is equipped, do not perform long-term sealed storage. The plastic casing and circuit board cleaners produce excessive chemical gas concentrations that damage the liquid crystal and polarization. board.</p><p><br></p><p>4. It should be prevented from squeezing the LCD screen forcefully. There is an orientation film on the inner surface of the glass, which is easy to damage. Therefore, excessive pressure cannot be applied to the surface of the LCD screen to avoid damage to the alignment layer. When installing equipment, the pressure should be uniform, only pressing the sides of the device, not the middle, or tilting.</p><p><br></p><p>5. The LCD screen and LCD accessories must be stored and used within the specified temperature range. If the temperature is too high, the liquid crystal state disappears and becomes liquid, and the display surface is black, which does not work at this time. Please note that it can be restored after the temperature drops. If the temperature is too low, the liquid crystals begin to form ice, causing permanent damage.</p><p><br></p><p>6. Prevent the liquid crystal display glass from cracking. Because the display device is made of glass, it is prone to cracking. Therefore, when designing the liquid crystal screen, you must check the filter assembly method and assembly resistance and impact resistance.</p><p><br></p><p>The above is the analysis of the precautions for the use of LCD module and LCD accessories, I hope it will be helpful to everyone in their use.</p>
