Abstract
An LED scanning array driver chip and a regulation method capable of self-regulating brightness linear change are provided. The LED scanning array driver chip is provided with LED current non-linear automatic control circuits to automatically regulate the average current of LEDs for the brightness of the LEDs to become bright or dark linearly, enabling each LED of the LED array to control the current non-linear change individually. This greatly reduces the time resource for a MCU to write registers inside the driver chip.
