Abstract
The invention discloses an OLED driving method and device. The method mainly comprises the steps that image data are stored into a frame storage first, then, each frame of image data is dynamically analyzed, a corresponding driving time sequence is generated according to the characteristic whether each line of image data are the same or not, the image data are corrected according to the line number of the same line, and finally through line drivers and row drivers, the lines with the same data in each frame of image are driven to be lightened at the same time. For the reason that the lightening time is prolonged in the frame period and a driving level is lowered, the requirement for peak luminance is lowered under the condition that the average brightness of an OLED display is not affected. According to the scheme, the requirement for peak luminance of an OLED component is lowered, and the service life of the OLED component can be obviously prolonged; meanwhile, due to the lowered driving level, the power consumption of the OLED display can also be reduced; or under the condition that the luminance, the service life and the power consumption are not affected, a PMOLED product with a larger size and a higher resolution ratio can be manufactured.
