The invention provides a display panel, a short-circuit protection method of the display panel and a display device. The display panel comprises a short-circuit protection circuit, a pixel driving circuit and an organic light-emitting element, wherein the short-circuit protection circuit comprises a detection module and a control module; the detection module is electrically connected with an organic light-emitting element; the control module is electrically connected with the detection module and the pixel driving circuit; the detection module is used for detecting whether the organic light-emitting element is short-circuited or not; the control module is used for controlling whether the pixel driving circuit drives or not according to a detection result of the detection module. Accordingto the invention, the display panel comprises a plurality of rows and columns of pixel units, wherein each pixel unit comprises a short-circuit protection circuit, a pixel driving circuit and an organic light-emitting element. Therefore, the pixel driving circuit is prevented from outputting overlarge current to a short-circuited organic light-emitting element or other adjacent organic light-emitting elements, and the pixel driving circuit is prevented from burning the short-circuited 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] Such as 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...
