Abstract

The invention discloses a manufacturing method of a capacitive touch sensor. The manufacturing method comprises the following steps of: manufacturing a drive electrode pattern layer by using a transparent conductive layer pattern mask and a photoresist; manufacturing an insulating layer by using an insulating layer mask and a photoresist; manufacturing a sensing electrode pattern layer by using the transparent conductive layer pattern mask and a photoresist which has the stickability opposite to that of the drive electrode pattern layer, wherein the drive electrode pattern layer and the sensing electrode pattern layer are located at different sides of a plane where the insulating layer is located; and manufacturing an insulating protection layer by using the insulating layer mask and a photoresist. The invention further discloses a capacitive touch sensor, a touch screen and a display device. As the insulating layer and the insulating protection layer are manufactured by using the same mask, the consumption number of masks is reduced, and then, the manufacturing cost of the touch screen is reduced. Furthermore, the sensing electrode pattern layer and the drive electrode pattern layer which are provided with transparent conductive layer patterns are respectively formed at different sides of the insulating layer, so that electric field lines from a drive electrode to a sensing electrode are enabled to be more divergent, and the sensitive touch degree is increased.

Description

technical field [0001] The present invention relates to the field of touch technology, in particular to a capacitive touch sensor and its manufacturing process, as well as a touch screen and a display device including the capacitive touch sensor. Background technique [0002] The capacitive touch panel (touch screen) has gradually developed into a mainstream touch screen due to its good performance and user experience. Capacitive Touch Sensor (touch sensor) is the key component of capacitive touch screen. The structure of the existing capacitive touch sensor usually includes: a transparent insulating substrate, the first layer made on the transparent insulating substrate is a metal layer, the second layer is an insulating layer, and the third layer is an ITO (nano indium tin metal oxide) pattern layer, and the fourth layer is an insulating protective layer. figure 1 Shown is a schematic diagram of a triangular ITO pattern layer, the pattern composed of multiple white trian...
