The recommended power-up sequence is to apply VCC first, followed by VDD, and then the reset signal (RST#). This ensures proper initialization of the display controller.
The brightness of the display can be adjusted by applying a PWM signal to the BLK (backlight) pin. The frequency of the PWM signal should be between 100 Hz to 1 kHz, and the duty cycle can be adjusted to control the brightness.
The maximum operating temperature range for this display is -20°C to 70°C. Operating the display outside of this range may affect its performance and lifespan.
The display is designed to operate in a relative humidity range of 40% to 80%. Operating the display in a humid environment above 80% may cause condensation, which can affect its performance and lifespan.
The recommended interface clock frequency for this display is up to 30 MHz. However, the actual clock frequency may vary depending on the specific application and system design.
