Застереження щодо використання РК-дисплею:
1. Prevent the application of DC voltage:
The DC component of the driving voltage should be as small as possible, and the maximum value should not exceed 50mV. If excessive DC components are applied for a long time, electrolysis and electrode aging will occur, which will reduce the service life.
2, UV radiation should be prevented:
Liquid crystals and polarizers are organic substances, which will undergo photochemical reactions and degradation under ultraviolet radiation. Therefore, when assembling liquid crystal display devices, consider whether it is necessary to install an anti-ultraviolet filter or other anti-ultraviolet methods in the front according to its purpose and use environment. Avoid long-term direct sunlight when using it.

3. Prevent the erosion of harmful gases:
Рідкі кристали і поляризатори є органічними, а в середовищі шкідливих газів відбуваються хімічні реакції та руйнування. Тому при їх використанні слід проводити заходи ізоляції шкідливих газів. Крім того, після того, як вся машина зібрана, не зберігайте її в закритому вигляді протягом тривалого часу, щоб запобігти пластиковим корпусам і пластиковим оболонкам. Надмірна концентрація хімічного газу, що утворюється засобом для чищення друкованої плати, пошкоджує рідкий кристал і поляризатор.
4. It should be prevented from being squeezed by force:
LCD is made of two pieces of glass, between them is only 510um, which is very thin. Moreover, the inner surface of the glass is coated with a layer of oriented film, 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. In case of excessive pressure or hand-pressing of the device during the assembly process, it shall be allowed to stand for an hour before turning on the power. Remember not to have drastic temperature changes during the power-on process. The pressure should be even when installing, only press the side of the device, not the middle, or tilt and force.
5. Because the segment code LCD exceeds a certain temperature range, the liquid crystal state will disappear:
Therefore, it must be stored and used within the specified temperature range. If the temperature is too high, the liquid crystal state will disappear and become liquid, the display surface will be black, and it will not work. Please be careful not to power on at this time, and it can recover by itself after the temperature drops. If the temperature is too low, the liquid crystal begins to freeze, causing permanent damage. In addition, if stored at extreme temperatures for a long time or subjected to vibration or shock, the LCD will also generate bubbles.
6. Prevent segment LCD glass from breaking:
Because the display device is made of glass, if it is lost, the glass will definitely break. Therefore, the assembly method and the vibration and impact resistance of the assembly must be considered when the whole machine is designed.
