Title:
DISPLAY MODULE AND DRIVING METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2020/256385
Kind Code:
A1
Abstract:
A display module includes a display panel including an inorganic light emitting element and a pixel circuit configured to provide a driving current to the inorganic light emitting element; and a driver configured to drive the pixel circuit. The pixel circuit includes a pulse amplitude modulation (PAM) circuit configured to control an amplitude of the driving current based on an applied PAM data voltage, and a pulse width modulation (PWM) circuit configured to control a pulse width of the driving current based on an applied PWM data voltage. The driver includes a power supply circuit configured to provide, to the PAM circuit, a first power supply voltage for driving the PAM circuit, and provide, to the PWM circuit, a second power supply voltage for driving the PWM circuit.
