Abstract

The invention discloses a brightness compensation method for supporting different update frequencies of a display panel, which comprises the following steps that (a) when the update frequency of the display panel is a first update frequency, compensating the display panel by using first brightness unevenness removal compensation data corresponding to the first update frequency; (b) when the update frequency of the display panel is changed from the first update frequency to the second update frequency, the display panel is still compensated by using the first brightness unevenness removal compensation data; and (c) the display panel is compensated by using a specific brightness compensation technology.

Description

technical field [0001] The present invention is related to display technology, in particular to a brightness compensation method supporting different update frequencies of a display panel. Background technique [0002] Please refer to Figure 1A to Figure 1C and figure 2 . Figure 1A to Figure 1C Schematic diagrams of several common dimming methods that can support different update frequencies of the display panel, such as Extend Vertical Front Porch (VFP), T1A and Skip frame; figure 2 It is a schematic diagram of the display panel PL respectively receiving the gate clock signal GCLK from the gate driving circuit and the source clock signal SCLK from the gate driving circuit. [0003] Such as Figure 1A and Figure 1C As shown, when the extended vertical frontier dimming method and the frame skip dimming method are used for dimming the display panel, since the extended vertical leading edge dimming method and the frame skip dimming method operate at a higher update freq...
