Before using our products, please read enclosed advice carefully.
This advice will guide you using our LCD and LCM products rightly and safely, saving our products from any damages arising from improperly shipping, storing, installing and unwise use. When you receive our products, if any obviously broken in external package or any quality problem is found, please keep it intact and contact us for early solution.
While shipping, storing and using, our LCD and LCM must be exposed to the given temperature. For LCD, storage and shipment temperature range is -10oC~60oC, operating temperature within 0oC~50oC. If wide temperature is requested, please state in your purchase order or subject to the certificate of the customers sample confirmation for LCM the storage temperature range shall be 5oC~45oC and the moisture shall be 40~60% The storage environment should be dry, free-dust, clean and well ventilated.
DC voltage can not be applied to LCD, and the max. DC component of the driving voltage shall not exceed 50mV. While welding LCM, only I/O interface shall be welded with a soldering iron below 260oC, less than 3~4 seconds / per welding, and less than 3~4times for each pint welding Top quality flux is preferred clean PCB after welding.
Keep LCD and LCM away from moisture, which will lower the glass surface resistance, corrode LCM electrodes and result in abnormal display. While installing LCD, adequately large contact area for devices conducting wire shall be ensured, and the pressure on the whole contact area shall be kept evenly. (the screwing pressure should be even)The fixing structure shall be even and smooth, and the pressure from fixing structure shall be transferred evenly to the sealing structure surrounding the device.
While installing LCM, the operator shall surely keep landing, so do the soldering iron and other appliances used. Protect the LCD surface carefully. Keeping flying flux away otherwise the surface may be damaged. Devices shall not be exposed to direct sunshine or ultraviolet ray over a long time, or its lifetime will be shortened.
Devices shall not be kept in an environment of high temperature, high moisture, or with corrosive and volatile chemicals. Otherwise, LCD may be discolored and LCM electrodes can be corroded, resulting in the loss of normal display function. LCM shall be packed or contained with anti-static materials. LCD polarize can not be contacted with organic solvent. LCD polarizes are soft materials. Its easy to be damaged by hard objects and coarse cloth etc. while you install your devices with LCD. While installing our products, please make the inspecting tools and instruments precisely and surely.
When you want to drive the LCD, the operating voltage applied to the device shall be within the set voltage ranger. While installing and using our products, if any quality problems arising from JHD are found, and you will reject the products, please keep or restore the product as it was (no broken glass, no polarize damage arising from scratch or hurt. As to products with pins pins shall keep intact. No shortened or bend pins), so that we can make our analytic testing and judgment. In the course of product supply,
if you want to do any modification in operating conditions, change design or function, please inform us as soon as possible. We will meet your specific requirements by changing our materials, technique or design accordingly, if possible.
While using our products, If any quality problems of mass products are found, please reject the products to us within three months upon your receipt of the products. If just a small quantity or individual product(s) you will reject, then please send back to us within half a year upon your receipt of them. After we have made analytic testing and proven the quality problem is caused by us, We will replace the product(s) accordingly. |
