Problems solved by technology
Since the operating space for the pressure touch operation in the raised area is small, the center of the press is basically the center of the area. When the user performs the pressure touch operation in the center of the raised area, compared with the user performing the pressure touch operation in the center of the conventional rectangular touch screen. The distance between the time-controlled frame area and the pressing center, the distance between the first frame area and the pressing center in the special-shaped touch screen is small, therefore, the angle between the strain axis direction of the first frame area and the short side of the touch screen is no longer in Near 45° or -45°, if the first strain detection direction is still at an angle of 45° with the short side of the touch screen and the second stress detection direction is at a -45° angle with the short side of the touch screen, It will cause poor performance of the pressure sensor in the first border area, and cannot effectively detect the pressure touch operation

The invention discloses a display panel and a display device. The display panel includes at least one notch, at least one side of the notch includes a raised structure, the non-display area includes at least one first non-display area arranged along the edge of the raised structure, and at least one first pressure is arranged in the first non-display area Sensor; the angle between the first strain detection direction of the first pressure sensor and the first edge of the display panel is greater than or equal to 65° and less than or equal to 115°, and the angle between the second strain detection direction and the first edge of the display panel is greater than or equal to -25° and less than or equal to 0, wherein the control chip is disposed in the non-display area, and the first edge is the edge of the display panel close to the control chip. The technical solution provided by the embodiment of the present invention improves the detection strength of the pressure signal of the first pressure sensor, so that the first pressure sensor can effectively detect the user's pressure touch operation.
Description
technical field [0001] Embodiments of the present invention relate to display technologies, and in particular, to a display panel and a display device. Background technique [0002] The appearance of the touch screen makes the user get rid of the keyboard and mouse operation, and the human-computer interaction becomes more straightforward. In order to better meet user requirements, a pressure sensor for detecting the magnitude of the touch pressure when the user touches the touch display screen is usually provided in the touch display screen. [0003] For a conventional rectangular touch screen, when the user performs a pressure touch operation on the center of the touch screen, the angle between the main axis of strain in the frame area of the touch screen and the short side of the touch screen is almost 45° or -45°. There is a very small part of the frame area where the angle between the principal axis of strain and the short side of the touch screen is around 0°. Ther...
