Abstract

The invention relates to the technical field of display, in particular to a display panel brightness compensation control method and a display panel brightness compensation control system. The displaypanel brightness compensation control method comprises the steps of: acquiring brightness data of a display panel, wherein the brightness data of the display panel is obtain through sensing the samegray-scale pure color signal driving pixels of the display panel to emit light; dividing the brightness data of the display panel into a plurality of regional brightness data sets, and dividing the brightness data of the display panel according to a plurality of light-emitting regions of the display panel, wherein the plurality of regional brightness data sets comprise a brightness data set located in a central region of the display panel and a brightness data set located in a non-central region of the display panel; taking the brightness data set of the central region as reference data, and calculating a brightness compensation coefficient of the pixels of the non-central region; and adjusting a compensation voltage of the pixels in the non-central region through using the brightness compensation coefficient, so that the display panel emits light uniformly. According to the display panel brightness compensation control method, the data storage space can be saved, the operation rate isincreased, and the uniformity of the brightness of the display panel is improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a brightness compensation control method and a brightness compensation control system of a display panel. Background technique [0002] Organic light emitting diode (Organic Light Emitting Display, OLED) display panel has self-illumination, low driving voltage, high luminous efficiency, short response time, high definition and contrast, wide operating temperature range, and can realize flexible display and large-area full-color display And many other advantages, it is recognized by the industry as the display panel with the most development potential. [0003] For an OLED display panel, each pixel includes an OLED device and a driving circuit for driving the OLED device to emit light. Since the power supply voltage is affected by the impedance of the power supply wiring during the transmission process, a voltage drop occurs, so that the current flowing through each dr...
