Embodiment Construction
[0023] In order to facilitate the understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. Preferred embodiments of the application are shown in the accompanying drawings. However, the present application can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the application more thorough and comprehensive.
[0024] see Figure 1-Figure 2 , an array substrate, comprising an array substrate row drive circuit, the output end of the array substrate row drive circuit is provided with a TFT device 211, the TFT device 211 includes a plurality of TFT units arranged at intervals, and the TFT unit includes a first type of TFT unit 101, a second TFT unit The second type TFT unit 201, the third type TFT unit 401 and the fourth type TFT unit 301, the sour...

The present invention relates to an array substrate, a display panel, and a display device. A TFT device at an output end of an array substrate row driving circuit includes a plurality of spaced TFT cells; grid electrodes of the respective TFT cells are connected to each other, drain electrodes of the respective TFT cells are connected to each other, and source electrodes of the respective TFT cells are connected to each other; cascading with the array substrate row driving circuit and a driven unit can be achieved through the grid electrodes of the first type of TFT cells, the drain electrodes of the second type of TFT cells, and the source electrodes of the third type of TFT cells to complete corresponding functions of the TFT device. Since the fourth type of the TFT cells are only connected to other units of the TFT device, and when the fourth type of the TFT cells fail, the fourth type of the failed TFT cells can be directly removed, normal working of the TFT device will not be affected, and normal output of the driving signal can be still performed. The risk that the array substrate row driving circuit cannot operate due to the TFT element failure can be effectively lowered, and the operational reliability of the array substrate row driving circuit is effectively improved.
Description
technical field [0001] The present application relates to the field of display technology, in particular to an array substrate, a display panel and a display device. Background technique [0002] Liquid crystal display panels are widely used in electronic products such as televisions, mobile phones, and digital cameras due to their many advantages such as thinness, lightness, and power saving. With the rapid development of liquid crystal display technology, higher production capacity and lower production cost have always been the pursuit goals of liquid crystal display panels. GOA (Gate Driver on Array, array substrate row drive) technology can be applied to the liquid crystal display panel, instead of an external IC (Integrated Circuit, integrated circuit), the driving circuit of the horizontal scanning line is made on the substrate around the display area, which effectively improves the display area. capacity and reduce production costs. [0003] However, the output of t...
