Capacitive touch screen and terminal

Abstract

The embodiment of the invention discloses a capacitive touch screen and a terminal, which have the capability of reducing and even removing the width of a side frame of the terminal. The capacitive touch screen comprises base plates of a first surface and a second surface, a first graph, and a first outlet line, wherein the first graph and the first outlet line are formed on the first surface of the base plate; some area on the first surface of the base plate is covered by the first graph; the first outlet line is formed within the area on the first surface of the base plate out of first graph; the capacitive touch screen further comprises a second graph and a second outlet line which are formed on the second surface of the base plate, wherein some area of the second surface of the base plate is covered by the second graph; and the second outlet line is formed on the area on the second surface of the base plate out of the second graph, wherein the first surface and the second surface are two opposite surfaces of the base plate, and the vertical projection of the second graph on the first surface at least covers the area on the first surface out of the first graph.

Description

technical field [0001] The present invention relates to the field of terminals, in particular to a capacitive touch screen and a terminal. Background technique [0002] With the development of technology, the application of capacitive touch screen technology occupies a dominant position in smart portable devices. like figure 1 As shown, the capacitive sensing device of the touch screen located above the liquid crystal display 7 (LCD, Liquid Crystal Display) is plated on the substrate 6 with a layer of transparent conductive material, such as indium tin oxide (ITO, Indium Tin Oxide) material, According to the requirements of the touch integrated circuit (IC, Integrated Circuit), it is etched into a corresponding conductive pattern, usually using an ITO material, that is, an ITO pattern. In the prior art, each conductive pattern usually includes a horizontal slider and a vertical slider. The horizontal slider is the horizontal electrode (X electrode), which is a transparent ...

Problems solved by technology

[0004] Since the outlet area without touch function needs to be included outside the graphic area with touch function, in the existing design, such as image 3 and Figure 4 As shown, it is necessary to reserve a certain border area outside the touch screen area of ​​the fuselage for displaying, which leads to the problem that the border of the current capacitive touch screen is relatively wide

Under the trend of thinning the terminal and maximizing the display area of ​​the touch screen, compressing the width is particularly important. However, in the current technical solution, since the outgoing line area cannot be touched by the touch screen, no matter how compressed the width of the outgoing line area, the frame cannot be completely eliminated. The existence of , goes against the general trend of compressing the terminal width
