Abstract

The embodiment of the invention discloses a display device. The display device comprises a display panel and a plurality of induction antenna loops, the display panel comprises a display area, the display area comprises a plurality of wiring areas, each wiring area is provided with a plurality of induction antennas, and the induction antennas are arranged at intervals in the first direction; the plurality of induction antenna loops are arranged on the display panel, the plurality of wiring areas are respectively provided with one induction antenna loop, and each induction antenna loop comprises a plurality of induction antennas on the corresponding wiring area. The induction antenna on the display panel is divided into the multiple wiring areas, the multiple wiring areas are each provided with one induction antenna loop, the resistance of the induction antenna loops can be reduced, and the accuracy of touch induction positioning of the display device is improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display device. Background technique [0002] In our daily life, we often come into contact with various types of touch-sensitive screens, from mobile phones and tablets for personal consumption, to computers for living and working, to TVs for home use, and commercial displays for various application scenarios Wait. [0003] A general touch-sensing screen consists of two parts: a touch-sensing unit and a touch-sensing control circuit. The touch sensing unit is installed in front of the display screen to detect the position of the user's touch sensing, and transmit the received information to the touch sensing control circuit; the main function of the touch sensing control circuit is to receive the touch from the touch sensing unit. Control sensing information, convert it into contact coordinates, and then send it to the CPU, and it can receive and execute commands ...
