A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the signal traces short and away from the power planes. Use a common mode choke or ferrite bead to filter the power supply.
Adjust the VCOMH voltage (typically between 2.5V to 3.5V) to optimize brightness. For contrast, adjust the VGH and VGL voltages (typically between 10V to 15V) to achieve the desired level.
The recommended clock frequency is 30 MHz to 60 MHz. However, the actual frequency may vary depending on the specific display module and system requirements.
Power on the display in the following sequence: VDD, VGH, VGL, and finally, the clock signal. Ensure a minimum delay of 10 ms between each power-on step.
The maximum operating temperature range is -20°C to 70°C. However, the display's performance may degrade at extreme temperatures.
