Problems solved by technology

This also brings the complexity of the touch panel manufacturing process
[0003] In the existing touch technology, touch is usually divided into self-capacitive touch and mutual-capacitive touch, because the self-capacitive touch technology needs to provide touch driving signals to the same touch electrode and receive its The touch sensing signal transmitted by itself reduces the touch accuracy of the touch panel
However, mutual capacitive touch usually sets two touch electrode layers on the touch panel. In this way, the number of film layers of the touch panel is increased, resulting in thicker touch panel and more complicated process, thereby reducing the cost of the touch panel. Yield rate of touch panel

Abstract

The invention discloses a touch panel. The touch panel comprises a substrate, and a touch electrode layer arranged on the substrate; the touch electrode layer comprises multiple first touch electrodes and multiple second touch electrodes; the first touch electrodes extend along a first direction and are arranged along a second direction which intersects with the first direction; the second touch electrodes are in array arrangement; the row direction of each second touch electrode is parallel with the first direction, and the column direction of each second touch electrode is parallel with the second direction; the multiple second touch electrodes are arranged between each two adjacent first touch electrodes; and an insulating bump is arranged between each first touch electrode and each adjacent second touch electrode. As the first touch electrodes and the second touch electrodes are arranged at the same touch electrode layer, and the insulating bumps are arranged between the first touch electrodes and the second touch electrodes, the touch precision can be improved while the number of the film layers of the touch panel is reduced.

Description

technical field [0001] The present application relates to the field of display technology, and in particular to a touch panel, a manufacturing method of the touch panel, and a touch device. Background technique [0002] With the improvement of touch technology, touch panel technology is also developing in a diversified direction. Users prefer touch panels with touch functions, high resolution, and thin and light. The production of the touch panel is also gradually developed in order to meet the needs of the market. This also brings about the complexity of the manufacturing process of the touch panel. [0003] In the existing touch technology, touch is usually divided into self-capacitive touch and mutual-capacitive touch, because the self-capacitive touch technology needs to provide touch driving signals to the same touch electrode and receive its The touch sensing signal transmitted by itself reduces the touch accuracy of the touch panel. However, mutual capacitive touc...
