Embodiment Construction

[0062] Figure 1A It is a system diagram of an OLED display according to an embodiment of the present invention. Please refer to Figure 1A , in this embodiment, the OLED display 100 includes a driving circuit 110 and an OLED display panel 120 . The driving circuit 110 is coupled to the OLED display panel 120 and receives the original display frame ODF to output the positive pixel voltage PPV and the zero-grayscale pixel voltage PV0 to the OLED display panel 120 according to the original display frame ODF. Wherein, the positive pixel voltage PPV is used to drive some pixels (not shown) of the OLED display panel 120 to display the corresponding part of the original display frame ODF, and the zero-grayscale pixel voltage PV0 is used to control the OLED display panel 120 Some pixels (not shown) stop emitting light, which is equivalent to displaying black, so that the organic light emitting diodes can rest and slow down aging.

Abstract

The invention relates to an organic light-emitting display and a running method thereof. The organic light-emitting diode display comprises an organic light emitting diode display panel and a driving circuit, wherein the organic light-emitting diode display panel is provided with a plurality of pixels; the driving circuit is coupled with the organic light-emitting display and is used for receiving an original display picture; and the driving circuit is used for generating a first picture which corresponds to the original display picture and a second picture which is adjacent to the first picture in a polarity reversing way, and outputting zero-gray-scale picture element voltage to these corresponding picture elements in the organic light emitting diode display panel corresponding to negative polarity data in the first picture and the second picture. Due to the adoption of the method, aging of the organic light-emitting diode can be slowed down, and the service life of the organic light-emitting diode is prolonged.

Description

technical field [0001] The present invention relates to a display and its operating method, and in particular to an organic light emitting diode display and its operating method. Background technique [0002] In recent years, the development of flat-panel display technology has been constantly innovating. Among them, organic light-emitting diode (OLED) display has the advantages of power saving, ultra-thin thickness, light weight, self-illumination, no viewing angle limit, fast response, The advantages of high photoelectric efficiency, no need for backlight structure and color filter structure, high contrast, high luminance efficiency, high brightness, multi-color and color (RGB) component manufacturing capabilities, and wide operating temperature range are considered to be the most promising in the future. One of the flat display technologies with development potential. Therefore, in recent years, many display manufacturers have invested in the development of OLED displays...
