At present, most LCD screens use LED as the backlight source. LED is powered by DC. If the backlight power is not enough, it will flicker. The LCD screen of T6963C should be about 4 inches with a resolution of 240*128. The backlight is generally 5V and 100mA. You can use it as a reference.

Backlight flickering is mostly a hardware problem, unless the backlight control is performed by software. If the backlight is controlled by software, temporarily disconnect the software control line and connect the backlight directly to the power supply. If it still flickers at this time, it means that the backlight circuit has poor contact.

Thanks! That may be a hardware problem. The backlight is controlled by hardware.
