Touch control display panel and display device

Abstract

The invention relates to the field of touch screen display, and particularly provides a touch control display panel and a display device. The touch control display panel comprises public electrodes, pixel electrodes, processing modules, at least one first magnetic induction electrode and at least one second magnetic induction electrode, wherein the first magnetic induction electrode and the public electrodes are arranged in the same layer; the at least one first magnetic induction electrode is used for sensing magnetic field change in the first direction, and generating corresponding magnetic induction signals; the second magnetic induction electrode and the pixel electrodes are arranged in the same layer; the second magnetic induction electrode is used for sensing magnetic field change in the second direction and generating corresponding magnetic induction signals; the included angle of the first direction and the second direction is a non-zero angle; the processing modules are used for generating touch control signals according to the magnetic induction signals. An electromagnetic touch control function is integrated to the touch control display panel in an In-Cell (built-in) form, and meanwhile high-precision of editing input and lightening and thinning of the whole display device are considered.

Description

technical field [0001] The invention relates to the technical field of touch screen display, in particular to a touch display panel and a display device. Background technique [0002] In the fields of portable reading, portable office equipment, etc., the traditional capacitive touch display panel cannot perform text insertion and editing due to the low precision of capacitive touch, and cannot realize high-precision editing input, which can no longer meet the needs of users for touch display panels. basic needs. [0003] However, as a high-precision editing input mode, electromagnetic touch is difficult to integrate into display devices that require increasingly thinner and lighter. The main reason is that the most common integration method in the prior art is on the display panel Add a layer of electromagnetic touch panel to realize electromagnetic touch with active electromagnetic pen.

[0002] In the fields of portable reading, portable office equipment, etc., the traditional capacitive touch display panel cannot perform text insertion and editing due to the low precision of capacitive touch, and cannot realize high-precision editing input, which can no longer meet the needs of users for touch display panels. basic needs

[0003] However, as a high-precision editing input mode, electromagnetic touch is difficult to integrate into display devices that require increasingly thinner and lighter. The main reason is that the most common integration method in the prior art is on the display panel Add a layer of electromagnetic touch panel to realize electromagnetic touch with active electromagnetic pen

However, such an Out-Cell (external) mode not only affects the flatness of the entire device, but also directly leads to an increase in the thickness of the entire display device, which restricts the development of thinner and lighter display devices.
