4. Application Guidelines & Critical Notes
- Power Supply: The module requires a 1.8V (Typ.) logic power supply (VDD/VDDIO) for MIPI mode, along with AVDD (10V), VGH (18V), and VGL (-8V). A sequence or power management IC is recommended.
- MIPI Interface: The 4-lane MIPI interface requires careful PCB layout with controlled differential impedance (100Ω differential). The signals (D0-D3, CLK) are high-speed and must be routed with appropriate length matching and reference ground plane.
- Backlight Driver: An external constant current driver is required for the LED backlight. The design is 3S9P (3 series, 9 parallel). The total maximum current is 180mA (20mA per string), and the total maximum voltage is 9.9V (3.3V per LED). The recommended operating current for optimal lifetime is 140mA total.
- Display Configuration: The UPDN and SHLR pins can be used to configure the scanning direction (up/down, left/right). This is useful for adjusting the orientation of the display in the final product.
- Temperature Range: This module has an extended operating temperature range from -20°C to +85°C, making it suitable for industrial applications. The storage range is even wider (-55°C to +125°C).
- Handling Precautions: The module is sensitive to electrostatic discharge (ESD). Use proper grounding during handling. Do not apply excessive pressure to the display surface or flex the FPC sharply near the connector.
