Problems solved by technology

[0005] The problem solved by the present invention is to propose a CF substrate and a touch panel with a touch function, so as to solve the problem that a thicker conductive glue needs to be coated when the existing CF substrate and a TFT substrate are electrically connected. During the cloth process, it is easy to break the glue or the width and thickness of the glue are different, which will affect the conductivity

Embodiment 1

[0062] In order to clearly understand the technical solution of the present invention, firstly, the method for fabricating the CF substrate provided in the first embodiment is introduced.

[0063] First, step S11 is performed to provide a substrate 10 .

[0064] Such as figure 1 As shown, the substrate 10 includes a display area 101 and a sealant coating area 102 disposed around the display area 101 . The substrate 10 is made of a transparent material, such as glass.

[0065] Next, execute step S12, refer to figure 2 As shown, a first conductive layer is deposited on the substrate 10, and etched to form a plurality of driving electrodes 111 and a plurality of sensing electrodes 112, as well as a plurality of first connecting lines 113, and a plurality of first connecting lines 113 connect a plurality of driving The electrodes 111 are connected together to form a driving line, and also form the first ends 150 of a plurality of first pins 2, the first ends 150 of the first ...

Embodiment 2

[0087] The structure and manufacturing method of the CF substrate provided in the second embodiment and the touch panel including the CF substrate are as follows:

[0088] Firstly, step S11 is performed to provide a substrate, which includes a display area 101 and a sealant coating area 102 arranged around the display area 101 .

[0089] Executing step S12, depositing a first conductive layer on the display area 101 of the substrate, and etching to form a plurality of driving electrodes 111, a plurality of sensing electrodes 112, and a plurality of first connection lines 113, the plurality of first connection lines 113 will A plurality of driving electrodes 111 are connected together to form a driving line, and simultaneously form a plurality of first ends 150 of the first pins 2, and the first ends 150 of the plurality of first pins 2 are respectively connected to the driving electrodes 111 or sensing The electrodes 112 are connected. In the second embodiment, if Figure 10...

Embodiment 3

[0094] Unlike the above two schemes, such as Figure 15 As shown, part of the first end 150 of the first pin in step S12 of the third embodiment is located in the display area 101 , and part is located in the sealant coating area 102 . Correspondingly, the cross-sectional structure of the formed touch panel (TFT substrate not shown) is as follows Figure 16 shown. In addition, the structure and manufacturing method of the CF substrate provided in the third embodiment and the touch panel including the CF substrate are the same as those in the first and second embodiments.

Abstract

A CF (Colour Film) baseplate with a touch function comprises a substrate, a touch control layer and a color filter layer and further comprises at least one first pin, wherein the first pin comprises a first end which is electrically connected with the touch control layer and a second end which is farther from the substrate than the first end. The invention further provides a touch panel comprising the CF baseplate. Through the adoption of the technical scheme provided by the invention, electric connection between the CF baseplate and a TFT (Thin Film Transistor) baseplate is realized, and the distance between corresponding pins of the CF baseplate and the TFI baseplate is reduced, that is, the thickness of conducting resin to be coated is reduced, so that the conducting resin is less susceptible to the phenomenon of resin gap and the electric conductivity is improved.

Description

technical field [0001] The invention relates to the field of touch display, in particular to a CF substrate with a touch function and a touch panel. Background technique [0002] As an input medium, the touch screen is currently the simplest, most convenient and natural way of human-computer interaction. Liquid crystal (Liquid Crystal), due to its good electrical controllability, is increasingly used in display panels. Therefore, usually the touch screen is integrated into the liquid crystal display panel to form various electronic products, such as mobile phones, notebook computers, MP3 / MP4 and so on. [0003] Touch panel, according to the display method of liquid crystal, currently widely used are twisted (Twisted Nematic, TN) display method, in-plane switching (In-Plane Switching, IPS) method and fringe field switching (Fringe Field Switching, FFS) method. Regardless of the display method, the touch panel generally includes a Color Film (CF) substrate, a TFT substrate, ...
