Problems solved by technology
[0003] In the prior art, in electronic devices that measure the touch pressure with a resistive pressure sensor, the pressure sensor is set in the non-display area, but the pressure sensor set in the non-display area will suffer from the change of resistance due to the pressure The distance between the position of the sensor and the pressing position is relatively large, so that the signal output by the pressure sensor is weak and the sensitivity is poor; the solution in the prior art increases the area of the non-display area, making the frame of the electronic device wider

The embodiment of the invention provides an array substrate, a touch display panel and a display device of the touch display panel, and relates to the technical field of display equipment. The array substrate is used for improving the sensitivity of bridge-type pressure sensors and reducing the frame width of the display device. The display area of the array substrate is internally provided with multiple bridge-type pressure sensors, each bridge-type pressure sensor comprises a first connecting bridge, a second connecting bridge, a third connecting bridge and a fourth connecting bridge, the first connecting bridge, the second connecting bridge, the third connecting bridge and the fourth connecting bridge are connected in a tail-end connection mode in sequence, wherein each first connecting bridge and each third connecting bridge extend in the first direction, and each second connecting bridge and each fourth connecting bridge extend in the second direction; the first direction is a data cable extension direction of the array substrate, and the second direction is a grid line extension direction of the array substrate. The array substrate is applicable to the display device.
Description
【Technical field】 [0001] The present invention relates to the technical field of display devices, in particular to an array substrate, a touch display panel and a display device thereof. 【Background technique】 [0002] At present, many electronic devices on the market can perform interface operations through touch. When a user touches the display panel with a finger, the display panel sends a signal to the electronic device. Among them, some electronic devices can detect the magnitude of the touch pressure through a resistive pressure sensor, that is, the magnitude of the touch pressure can be measured by detecting the change of resistance in the pressure sensor. [0003] In the prior art, in electronic devices that measure the touch pressure with a resistive pressure sensor, the pressure sensor is set in the non-display area, but the pressure sensor set in the non-display area will suffer from the change of resistance due to the pressure The distance between the position ...
