Abstract
A display driving device, a display driving method, a display module and a display device are provided. The display driving device includes: a PWM signal generating circuit configured to generate a PWM signal; a PWM signal acquisition circuit, configured to identify whether the PWM signal output by the PWM signal generating circuit is at a high level or a low level; a gamma voltage debugging circuit, configured to debug a gamma voltage to obtain a first group of gamma voltage reference data corresponding to the PWM signal at the high level and a second group of gamma voltage reference data corresponding to the PWM signal at the low level in each gray-scale image; and a gamma voltage switching circuit.
