Abstract

A display control method, a display control system, and a display device. The display control method is applicable to a display device including a display panel, and includes: receiving display data; counting brightness information of each column of display data in the display data and generating display data of each column Statistical table of brightness information of the data; according to the statistical table of brightness information of each column of displayed data and the pulse width compensation table, generate a correspondence table between the brightness information of each column of displayed data and the compensation pulse width; according to the correspondence between the brightness information of each column of displayed data and the compensation pulse width generating compensation display data from the table and display data; and generating a data driving signal and a scanning driving signal to the display panel according to the compensation display data, so that the display panel displays images. The present invention can effectively compensate the problem of brightness inconsistency of brighter grayscale values ​​in each pixel column of the display panel caused by early shutdown of data driving signals of darker grayscale values ​​to charge other pixels in the column.

Description

technical field [0001] The present invention relates to a display device, and in particular to a display control technology of the display device. Background technique [0002] A plurality of current-driven display components, such as organic light-emitting diodes, are configured in a current-driven display device. The luminous brightness of the current-driven display component is determined by the magnitude and time of the current passing through the current-driven display component. At present, the common practice is to control the current passing time by means of Pulse Width Modulation (PWM) to present different Brightness (grayscale value). [0003] figure 1 A schematic diagram of a typical display device 10 is shown. The display device 10 includes an image circuit 100 , a driving circuit 110 and a display panel 120 . The video circuit 100 outputs the display data signal 130 to the driving circuit 110, and the driving circuit 110 outputs the data driving signal 140 a...
