A display panel and a touch display device

Abstract

The embodiment of the present invention discloses a display panel and a touch display device. The display panel includes: a first substrate and a second substrate oppositely arranged, and the first substrate and the second substrate are bonded by a sealant; a plurality of pressure sensors , a plurality of pressure sensors are arranged on the side of the first substrate facing the second substrate, or a plurality of pressure sensors are arranged on the side of the second substrate facing the first substrate, wherein the pressure sensors include 4 resistors, and the sealing frame A projection of the glue in a direction perpendicular to the display panel covers at least one resistor in the pressure sensor. In the embodiment of the present invention, the projection of the sealing glue bonding the first substrate and the second substrate in the direction perpendicular to the display panel covers at least one resistor in the pressure sensor, which can reduce the occupied frame area and realize a narrow frame; after pressing , it can also increase the resistance value difference of the four resistors in the pressure sensor, accelerate the unbalance of the Wheatstone bridge structure, thereby improving the pressure-sensitive detection accuracy of the display panel.

Description

technical field [0001] Embodiments of the present invention relate to display technologies, and in particular to a display panel and a touch display device. Background technique [0002] With the rapid development of portable electronic terminal equipment, especially mobile phone and tablet technology, more and more new technologies are applied to these electronic terminal equipment. Pressure-sensing touch technology is a new technology that has received widespread attention in the field. The touch screen integrated with pressure-sensitive touch screen technology can clearly distinguish the difference between tap and press. When the user presses the screen, the touch screen integrated with the pressure sensor can accurately recognize the pressure conveyed by the user on the touch surface, and then realize different operations, such as calling up more control options in applications such as information, music and calendar. [0003] Existing pressure sensors are generally int...
