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

The invention provides a touch display panel and a touch display device. The touch display panel comprises a display area and a non-display area around the display area, wherein the display area is provided with multiple self-contained touch location detection electrodes; the non-display area is provided with a driving circuit and at least one pressure-sensitive touch unit; the display area is provided with multiple touch location lines and multiple virtual touch location lines; each self-contained touch location detection electrode is electrically connected with at least one touch location line; the multiple virtual touch location lines and the multiple touch location lines are insulated from each other and are arranged in parallel; and a first output end and a second output end of each pressure-sensitive touch unit are electrically connected with the driving circuit through a virtual touch location line separately. According to the touch display panel and the touch display device provided by the invention, the number of the lines arranged in the non-display area of the touch display panel can be reduced, and borders of the touch display panel can be reduced.
Description
technical field [0001] The present invention relates to the technical field of touch display, in particular to a touch display panel and a touch display device. 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 display panel, si...
