Embodiment Construction

[0032] Embodiments of the present invention provide an in-cell touch screen and a display device, which are used to reduce the influence of touch-sensing electrodes in the in-cell touch screen on image display.

[0033] In the embodiment of the present invention, a plurality of touch-sensing electrodes are arranged on the upper substrate (box-matching substrate), and each touch-sensing electrode is composed of a touch-sensing sub-electrode, or at least two (ie, multiple) are laterally distributed and parallel to each other. The plurality of touch sensing sub-electrodes distributed laterally and parallel to each other are connected in parallel with each other.

[0034] In the embodiment of the present invention, a plurality of touch driving electrodes are disposed on the lower substrate (array substrate), and each touch driving electrode is distributed in a longitudinal direction perpendicular to the touch sensing electrodes (that is, a direction perpendicular to the touch sensi...

Abstract

The invention discloses an in-cell touch panel and a display device, which are used for reducing the influence on image display by touch driving electrodes in the in-cell touch panel. The in-cell touch panel comprises an upper baseplate and a lower baseplate which are placed oppositely, as well as a plurality of touch induction electrodes arranged on the upper baseplate, and a plurality of touch driving electrodes arranged on the lower baseplate, wherein the touch induction electrodes are transversely distributed, and the touch driving electrodes are longitudinally distributed; and each touch induction electrode comprises one or more mutually parallel touch induction sub-electrodes which are transversely distributed, and are mutually connected in parallel.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an embedded touch screen and a display device. Background technique [0002] Touch Panel (TP) includes Add On Touch Panel and In Cell Touch Panel. [0003] In Cell Touch Panel integrates the touch driving electrodes and touch sensing electrodes of the touch screen into the display screen, realizing a touch display device with simple structure, high display performance and low cost, and improving the competitiveness of the product. In Cell Touch Panel has gradually become the mainstream in the display field. [0004] In the prior art, touch and display functions are realized by arranging touch driving electrodes and touch sensing electrodes on a color filter substrate and an array substrate of a display panel. [0005] In the current In Cell Touch Panel solution, the touch-sensing electrodes are set in a grid shape, such as figure 1 As shown in FIG. 2 , it is a schematic struc...
