Embodiment Construction

[0039] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0040] see figure 1 , figure 2 with Figure 2A , a touch screen electrode 100, including a substrate 110, a conductive layer 120 and photosensitive silver paste electrode leads 130. The substrate 110 includes a display area 112 and a frame area 114, the display area 112 matches the frame area 114, the display area 112 is located in the center, generally rectangular or square, and the display area 112 and the frame area 114 are complementary in shape. The bezel area 114 is generally located at the edge of the touch screen. The display area 112 displays a user operation interface, and the frame area 114 is used for arranging electrode leads. The conductive layer 120 is attached to the display area 112 and includes a plurality of conductive pattern regions 122 , and the plurality of conductive pattern regions 122 are insulated from each other...

Abstract

A touch screen electrode comprises a substrate, a conducting layer and light-sensitive silver paste electrode leads. The substrate comprises a display area and a frame area. Under a yellow light condition, through coating, exposure, development treatment, etching and peeling procedures, the conducting layer with a plurality of conducting pattern regions is formed in the display area of the substrate, an exposure developing mode is directly carried out on the frame area through silk-screen light-sensitive silver paste, the conducting pattern regions in the display area are obtained to form the conducting layer, the frame area is provided with the light-sensitive silver paste electrode leads with small wire widths and spacing, and the light-sensitive silver paste electrode leads are electrically connected with the conducting pattern regions to form a loop. Due to the fact that the light-sensitive silver paste electrode leads are obtained through the exposure developing mode, and therefore the wire widths and spacing can be reduced; the manufacturing method has simple procedures, reduces cost, and meanwhile avoids the bad phenomena of ink penetration-out, adhesion, jaggy edges and the like.

Description

technical field [0001] The invention relates to the technical field of touch screens, in particular to a touch screen electrode and a manufacturing method thereof. Background technique [0002] With the fierce competition in the touch panel (touch panel, TP) industry, the touch screen technology is continuously updated and innovated. Currently, there are a large number of narrow-frame displays on the market, such as tablet computers, TV sets, mobile phones and so on. The frame of the display is mainly provided with electrode leads, and the smaller the line width and spacing of the electrode leads, the smaller the total width of the frame of the display and the narrower the frame. [0003] The traditional manufacturing method of narrow-frame touch screen electrodes is to remove excess tin-doped indium oxide (Indium Tin Oxide, ITO) on the transparent conductive layer by etching, leaving a circuit pattern, and then printing silver paste to form electrode leads, so that the elec...
