Embodiment Construction

[0042] The present disclosure will now be described more specifically with reference to the following examples. It is noted that the following descriptions of some embodiments are presented herein for purposes of illustration and description only. It is not intended to be exhaustive or to be limited to the precise forms disclosed.

[0043] FIG. 1A and FIG. 1B show that electrostatic discharge occurs in a black matrix layer in a conventional touch substrate. Referring to FIG. 1A , in the peripheral region of a conventional touch substrate, the touch electrode layer TEL is disposed on the black matrix layer BML. The touch electrode layer TEL includes a plurality of touch electrode blocks TE separated by gaps G1 , as shown in FIG. 1A . It is intended to insulate adjacent touch electrode blocks by separating the touch electrode blocks, because the black matrix layer BML is made of insulating material and designed to have high resistance. For example, the black matrix layer BML ...

Abstract

The present application discloses a touch substrate, which includes: a base substrate (BS); a black matrix layer (BML) located on the base substrate (BS) in the black matrix area (BA) of the touch substrate; and The side of the black matrix layer (BML) away from the base substrate (BS) is in the touch electrode layer (TEL) in the touch electrode area (TEA) of the touch substrate. The touch electrode area (TEA) partially overlaps with the black matrix area (BA) to form an overlapping area (OA). The touch electrode layer (TEL) includes a plurality of touch electrode blocks (TE) at least partially located in the overlapping area (OA). The touch electrode block (TE) at least partially located in the overlapping area (OA) is separated from the adjacent touch electrode block (TE) by the first gap (G1). The thickness of the black matrix layer (BML) in at least a portion of the region of the first gap (G1) near the base substrate (BS) is reduced relative to the remaining portion of the black matrix layer (BML).

Description

technical field [0001] The invention relates to a touch substrate, a display panel and a display device having the touch substrate, and a manufacturing method of the touch substrate. Background technique [0002] In recent years, touch devices have been widely used in many electronic devices, such as mobile phones, computer display panels, touch screens, satellite navigation devices, digital cameras, and the like. Examples of touch devices include mutual capacitive touch devices and self capacitive touch devices. In the mutual capacitance touch device, the touch electrodes may be touch scanning electrodes (Tx), and the touch sensing electrodes (Rx) may be disposed on the color filter substrate. In a self-capacitance touch device, the touch electrode can independently realize the touch function. [0003] When a user's finger performs a touch function on the touch panel, static charges accumulate on the touch panel. When electrostatic charge is transferred to the touch elec...
