Abstract

The invention discloses a color-film substrate and a production method thereof and a touch panel. The color-film substrate comprises a substrate body, multiple first electrodes extending along the first direction are arranged on the first side of the substrate body, and a multiple second electrodes extending along the second direction are arranged on the second side of the substrate body. The touch scan electrodes and the touch sensitive electrodes with a touch function are respectively arranged on two sides of the substrate body, one-step composition technology can be performed on two sides of the substrate body respectively, diagrams of the touch scan electrodes and the touch sensitive electrodes are formed respectively, and only two masks are needed correspondingly to the above two-step composition technology; compared with the prior art, the color-film substrate and the production method thereof have the advantages that the number of the masks used for the touch electrodes can be effectively reduced during production of the color-film substrate, and production cost is thereby effectively lowered.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a color filter substrate, a preparation method thereof, and a touch screen. Background technique [0002] The touch screen (Touch Panel) is a system for positioning by calculating the coordinates of touch points in the screen, and consists of a touch detection part and a touch controller. The touch detection part is installed in front of the screen to detect the user's touch position, and then send the detected information to the controller, convert it into coordinates, and send it to the central processing unit, while receiving the signal returned by the central processing unit and To implement, to achieve human-computer interaction. [0003] figure 1 It is a top view of a touch screen in the prior art, figure 2 for figure 1 A schematic cross-section of the touch screen shown, as figure 1 and figure 2 As shown, it includes: an array substrate 2 and a color filter substr...
