1. Basic specifications

The required TFT Lcd screen size, resolution, communication interface type between motherboard and TFT screen, display viewing angle, touch type selection, external dimensions, structural design, voltage, connection method of FPC cable, or specified Hongcai model.

 
2. Drawing Confirmation

According to the needs of communication and verification, as well as standard or customized materials, such as resistive touch or capacitive touch, wiring FPC or backlight, arrange the structural drawings of TFT Lcd display screens to customers for confirmation within 2-3 days.

 
3. Sample making

The sample delivery time for standardized tft display is 2-3 days. For customized lcd display, samples are made according to the confirmed drawings. Sample production takes time. The sample delivery cycle of Lcd screens is generally 7-12 days. The cycle time is 18-21 days.

 
4. Sample delivery

After the sample production is completed, it will be inspected according to the sample delivery process, and a series of structural and electrical performance tests, high and low temperature and thermal shock aging tests, vibration tests, salt spray tests, etc. will be arranged according to the quality control procedures, and tests will be carried out according to the requirements of different customers , Provide the actual test report of the tft display to ensure the reliable performance of the tft display.

 
5. Technical service
