Problems solved by technology

However, in addition to the pressure-sensitive touch unit occupying the non-display area of ​​the display panel, since each pressure-sensitive touch unit is equipped with multiple signal lines connected to the driver chip or connected to the pressure-sensitive detection circuit, on the one hand, it will occupy other signal lines of the original display panel. The space between the signal lines is shortened, which is easy to cause short circuit or coupling. On the other hand, the signal line connected to the pressure-sensitive touch unit will also make the frame of the display panel wider, which is not in line with the current development trend of narrow frame

Abstract

The present invention provides a touch display panel and a device. The touch display panel includes a display area and a non-display area surrounding the display area. The non-display area is provided with at least one pressure-sensitive touch unit; the display area is provided with There are a plurality of touch position detection electrodes; the touch display panel also includes a plurality of touch position traces; each of the touch position traces is electrically connected to the corresponding touch position detection electrode; In the detection stage, at least one signal line of the pressure-sensitive touch unit is multiplexed with one of the touch position lines, and the pressure-sensitive touch unit is used to detect the magnitude of the touch pressure. The present invention can reduce the number of wires arranged in the non-display area of ​​the touch display panel and reduce the frame of the touch display panel.

Description

technical field [0001] The present invention relates to the technical field of touch display, in particular to a touch display panel, a touch display device and a driving method. Background technique [0002] The pressure-sensing technology is to add a pressure-sensing device on the display screen. Touching the display screen with a finger and pressing it again will bring different interactive effects. That is to say, the screen can feel different strengths such as light touch, normal touch and heavy pressure, and more three-dimensional feeling of finger operation, which can realize more diverse operation methods. [0003] In the existing pressure-sensitive display panel, the pressure-sensitive touch unit is generally arranged in the non-display area of ​​the display panel, so as to prevent the pressure-sensitive touch unit from affecting the normal display of the display area. However, in addition to the pressure-sensitive touch unit occupying the non-display area of ​​the...
