Embedded electromagnetic touch display screen and touch display device

Abstract

The invention discloses an embedded electromagnetic touch display screen and a touch display device. The embedded electromagnetic touch display screen and the touch display device have the main advantages that a common electrode layer of an existing display panel is divided into transparent strip-shaped common electrodes, the strip-shaped common electrodes are electrically connected with one another and are electrically connected with a plurality of data lines, and the common electrodes and the data lines are distributed in a crossed manner, so that all the strip-shaped common electrodes have unified electric potential in display time, functions of the common electrode layer can be realized, and an aperture ratio of the display screen can be guaranteed; independent first-direction coil induction electromagnetic signals are formed by at least two common electrodes in touch time, independent second-direction coil induction electromagnetic signals are formed by at least two data lines in the touch time, induction coordinates can be determined according to induced currents, and accordingly an electromagnetic touch effect can be realized by equipment of the display screen without other additional equipment.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an embedded electromagnetic touch display screen and a touch display device. Background technique [0002] With the rapid development of display technology, touch screens (Touch Panel) have gradually spread throughout people's lives. Compared with the traditional display that can only provide display functions, the display using the touch screen can enable information interaction between the user and the display control host. Therefore, the touch screen can completely or at least partially replace the commonly used input device. Some monitors can not only display, but also touch control. [0003] Common touch screens are divided into resistive touch screens, capacitive touch screens, electromagnetic touch screens and infrared blocking touch screens. The existing electromagnetic touch screen generally integrates the LCD panel and the electromagnetic input function into the disp...
