Embodiment Construction

[0032] In order to enable those skilled in the art to better understand the technical solution of the present invention, a touch substrate and a display panel of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0033] At present, the mutual capacitive touch control structure usually consists of multiple columns of driving electrodes and multiple rows of sensing electrodes to form a touch cell array, and a single channel structure is used for conduction between the touch cells. The connection between the adjacent touch units in the same row or the same column is realized through the connection bridge.

[0034] In the field of handheld display devices, such as mobile phones, tablets, etc., the overall touch display is developing in a thinner and thinner direction. The distance between the display layer and the display layer is getting closer, so that the noise of the touch is increasing, res...

Abstract

The invention provides a touch substrate and a display panel. The touch substrate comprises a base and a plurality of touch units arranged on the base, each touch unit comprises a driving electrode and a sensing electrode, each driving electrode comprises a first main body part and a plurality of first limb parts, the first limb parts are located on the edges of the first main body parts, and thefirst limb parts are connected with the first main body parts; the induction electrode comprises a second main body part and a plurality of second limb parts, and the second limb parts are located onthe edge of the second main body part and connected with the second main body part; orthographic projections of the first limb part and the second limb part on the substrate are alternately occluded with each other. According to the touch substrate, the interaction area between the driving electrodes and the induction electrodes in the touch unit can be increased, the variable quantity of capacitance induction signals between the driving electrodes and the induction electrodes is increased, the touch semaphore between the driving electrodes and the induction electrodes in the touch unit is increased, and the touch precision and the touch sensitivity of the touch substrate are improved.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to a touch substrate and a display panel. Background technique [0002] In the field of touch display, there are many ways to set up touch screens, including on-cell and in-cell touch screens. Among them, the on-cell touch screen is characterized by its touch accuracy. It is favored for its advantages of high height and easy fabrication in display screens. [0003] At present, plug-in touch technology is mainly divided into two categories: self-capacitance touch and mutual-capacitance touch. Among them, the touch accuracy of the mutual capacitance touch is higher than that of the self-capacitance touch, and can support real multi-touch. Contents of the invention [0004] Aiming at the problems of low touch signal amount, touch precision and touch sensitivity in the current touch sensing pattern, the present invention provides a touch substrate and a display panel. ...
