The invention provides a display panel, a short circuit protection method of the display panel and a display device. The display panel includes a short-circuit protection circuit, a pixel drive circuit, and an organic light-emitting element; the short-circuit protection circuit includes a detection module and a control module; the detection module is electrically connected to the organic light-emitting element; the control module is electrically connected to the detection module and the pixel drive circuit; the detection module is used for Detect whether the organic light-emitting element is short-circuited; the control module is used to control whether the pixel driving circuit is driven according to the detection result of the detection module. In the present invention, the display panel includes multiple rows and multiple columns of pixel units. Wherein, a pixel unit includes a short circuit protection circuit, a pixel driving circuit, and an organic light emitting element. This prevents the pixel driving circuit from outputting excessive current into the short-circuited organic light emitting element or other adjacent organic light emitting elements. This also prevents the pixel driving circuit from burning out the shorted organic light emitting element or other adjacent organic light emitting elements.
Description
【Technical field】 [0001] The invention relates to the field of display technology, in particular to a display panel, a short-circuit protection method for the display panel, and a display device. 【Background technique】 [0002] In display technology, organic light emitting display panel (Organic Light Emitting Diode, OLED) is widely used in the industry due to its thinness, active light emission, fast response speed, wide viewing angle, rich color and high brightness, low power consumption, and high and low temperature resistance. It is recognized as the third generation display technology following the liquid crystal display panel (Liquid Crystal Display, LCD). [0003] figure 1 It is a schematic circuit diagram of a pixel unit in an existing display panel. [0004] like figure 1 As shown, in the prior art, a pixel unit of a display panel includes a driving transistor T1, a switching transistor T2, a bootstrap capacitor C and an organic light emitting element D. When th...
