Abstract

The present invention describes a driving method of organic light -emitting display panel, organic glow display device, and organic glowing display panel.Organic light -emitting display panels include: data cables and grille wires crossing with data cables; switching signal cables; pixel drive circuits, including the first voltage end of the high potential DC voltage, driving transistor, optical switch and luminous diode; optical switching connection connectionBetween the first voltage end and the light emitting diode; the optical component is located in the non -display area of the organic light -emitting display panel; the control circuit, including the storage module and the control module;Circuit power connection; control circuit The output duration of the capacity signal on the lighting stage according to the environment brightness of the sensing stage according to the environmental brightness of the sensitivity.So as to control the accumulation of brightness displayed in different environmental brightness in the pixel circuit, the brightness compensation is simply and effective.

Description

technical field [0001] The present invention relates to the display field, in particular to an organic light emitting display panel, an organic light emitting display device, and a driving method for the organic light emitting display panel. Background technique [0002] In recent years, various light-weight and small-sized flat panel display devices have been developed instead of cathode ray tubes. Examples of these flat panel display devices include liquid crystal display panels, plasma display panels, and electroluminescent display panels. Among them, the electroluminescent display panel realizes the normal display of the display panel through the electroluminescent device in the display panel. According to the different materials of the light-emitting layer, the electroluminescent device is divided into two types: inorganic light-emitting and organic light-emitting. Response speed, high luminous efficiency, strong brightness, and wide viewing angle are called the new ge...
