Abstract

The invention provides a detecting method and a device of pixel charging compensation, its compensation method and a display device. The detecting method includes steps of classifying a display zone of the display device into at least two compensation zones, and detecting the first brightness of a target pixel in every compensation zone; calculating the compensation time of charging the pixel in the compensation zone where the target pixel locates according to the differential value of the first brightness and the preset brightness. Thus, after compensating the pixel charging time in the compensation zone by the detected compensation time, the charging time of every pixel is approximately the same, so that the charging difference of pixels on different positions caused by the improvement of resolution rate, pixel density and image refreshing rate and delay of the signal line is reduced, the charging uniformity and sufficient charging time of pixels at different positions are guaranteed; besides, the brightness of different positions on the display zone of the display device is uniform.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a detection method and device for pixel charging compensation, a compensation method thereof and a display device. Background technique [0002] The demand for various display devices has increased with the rise of the global information society. Therefore, great efforts have been devoted to the research and development of various flat display devices such as liquid crystal display devices (LCD), plasma display devices (PDP), electroluminescent display devices (ELD), and vacuum fluorescent display devices (VFD). . Due to its low power consumption, low cost, no radiation and easy operation, liquid crystal display devices have increasingly entered people's lives and work, and are widely used in various fields, such as homes, public places, offices, etc. Field and personal electronic related products, etc. [0003] At present, with the continuous improvement of the resol...
