3.3 General Precautions
- Safety: Liquid crystal is poisonous. Do not put it in your mouth. If liquid crystal touches your skin or clothes, wash it off immediately by using soap and water.
4. Application Guidelines & Critical Notes
Intended Use
- Industrial control panels and human-machine interfaces (HMIs)
- Portable media players and handheld devices
- Any application requiring a standard 7.0-inch display with a MIPI interface
Critical Design Considerations
- Interface (4-lane MIPI): This module uses a MIPI interface with 4 data lanes and 1 clock lane. The host controller must be capable of 4-lane MIPI operation for the 1024×600 resolution.
- Power Supply: Provide stable VDD (1.8V) for LCD power, AVDD (8V to 13.5V) for analog circuit, VCD_VGH (up to 40V) for Gate ON Voltage, and LCD_VGL (down to -20V) for Gate OFF Voltage. The backlight requires a constant-current LED driver set to 180mA at approximately 9.0V.
- Display Orientation Control: Pins UPDN (Pin 5) and SHLR (Pin 6) allow for vertical and horizontal inversion of the display. Refer to the mechanical drawing for the default orientation.
- Standby Mode: The STBYB (Pin 26) pin controls standby mode. Set to "H" for normal operation and "L" to turn off the timing controller and source driver (all outputs become High-Z).
- Mechanical Integration: Module outline: 164.9mm × 100mm × 2.8mm. Active area: 154.2144mm × 85.92mm. FPC connector: FH12A-30S-0.5SH (30-pin, 0.5mm pitch).
- Temperature Limits: Operating Temperature: -20°C to +60°C. Storage Temperature: -30°C to +70°C.
- Reset Sequence: Ensure the RESET pin (Pin 27) is held low for a sufficient period during power-up to guarantee proper initialization.
- Backlight LED Life: The LED life time is 20,000 hours (defined as module brightness decrease to 50% of original brightness at 1/2 rated current). Operating IL larger than 180 mA could decrease the LED life time.
Handling & Compliance
- Observe standard ESD precautions during handling and assembly.
- The module contains fragile glass and a 30-pin FPC – handle with care.
- Avoid bending the FPC sharply, especially near the connector interface.
- Do not attempt to disassemble or process the LCD module.
- Liquid crystal is poisonous. Do not put it in your mouth. If liquid crystal touches your skin or clothes, wash it off immediately by using soap and water.
