Disclosed is an OLED PWM pixel driving method. The method comprises: slicing a frame of image into a plurality of subfields different in weight, and splitting a subfield having a higher weight thereamong into secondary subfields in a predetermined splitting ratio; and rearranging the split secondary subfields from the subfield having a higher weight and non-split subfields according to an input image and the predetermined splitting ratio in order to eliminate an image display error.

OLED PWM pixel driving method

An OLED drive system raising a frame contrast and a drive method are disclosed. The OLED display panel is equally divided into a plurality of display divisions along a vertical direction. The brightness calculation module is employed to calculate average pixel brightnesses corresponding to the respective display divisions in the OLED display panel. On one hand, the power management module is employed to supply different reference voltages for the respective display divisions correspondingly according to the average pixel brightnesses of the respective display divisions in the OLED display panel, and respectively insert the reference voltages of the respective display divisions into reference voltage lines corresponding to the pixels of middle rows in the display divisions to make the reference voltages of the respective display divisions be different for raising the frame contrast.

OLED drive system raising frame contrast and drive method

The present invention provides a digital driving method of an OLED display device, and the input front end data analysis module analyzes the data signals of at least two adjacent frames of image, and the OLED display device divides the data signals of each frame of image in the at least two adjacent frames of image into a plurality of subframes according to an order of display times, and adjusts an order of various color components outputted by the plurality of subframes corresponded with the data signals of each frame of image according to an analysis result of the data signals of at least two adjacent frames of image to prevent the new integral effect generates between the two adjacent frames of image because the data signals are different, and thus to eliminate the flicker and raising the image display quality.

Digital driving method of OLED display device

The present invention discloses a display device, comprising a display panel, a data driving circuit, and a scan driving circuit, the data driving circuit being disposed on a side of the display panel in a first direction, the scan driving circuit being disposed on a side of the display panel in a second direction, the first direction being perpendicular to the second direction; both the data driving circuit and the scan driving circuit are connected to the display panel. The present invention can reduce a width of a non-display region of the display device under a premise of improving a display quality.
