Abstract
(EN)
A brightness adjusting method for a display system comprises the following steps: writing a first drive signal to a display panel (S1); controlling simultaneous turning on of a first lens and a backlight module, wherein multiple light-emitting elements of the backlight module are simultaneously turned on, and the first lens and the multiple light-emitting elements of the backlight module are simultaneously turned on (S2); adjusting a first drive current of each light-emitting element (S3); writing a second drive signal to the display panel (S4); controlling simultaneous turning on of a second lens and the backlight module, wherein the multiple light-emitting elements of the backlight module are simultaneously turned on, and the second lens and the multiple light-emitting elements of the backlight module are simultaneously turned on (S5); and adjusting a second drive current of each light-emitting element (S6).
