Abstract

The invention provides a touch sensing device, a touch panel, a display panel and a display device, wherein the touch sensing device comprises an inductance graphics formed on a substrate, and a sensing circuit connected with the inductance graphics; the sensing circuit is used for applying a preset alternating current (AC) signal onto the inductance graphics and comparing a sensing signal coming from the inductance graphics with the preset AC signal for sensing a touch action. On this basis, the display panel can realize inductance type touch sensing. Compared with capacitive touch, the display panel can increase a touch sensing distance on a surface of the touch panel and improves the accuracy and sensitivity of touch, thus achieving a better touch effect.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a touch sensing device, a touch panel, a display panel and a display device. Background technique [0002] In the prior art, the touch screen can be a very intuitive, convenient and fast human-computer interaction mode, and has gradually extended from the fields of personal consumer electronics such as mobile phones, tablet computers, and notebook computers to every corner of production and life. At present, capacitive touch screens are the mainstream form of touch screens, mainly including OGS (One Glass Solution, integrated touch), GG (Glass-Glass, double-glass lamination) and GFF (Glass-Film-Film, double-film lamination) and other types. . However, the capacitive touch screen can only sense the touch of the finger when the outer surface is close enough to the finger (such as less than 0.5mm), and it cannot sense when the user wears a thicker insulating medium such as...
