Capacitive touch screen and terminal

Abstract

Embodiments of the present invention disclose a capacitive touchscreen and a terminal, which can reduce or even eliminate a width of a terminal border. The capacitive touchscreen includes: a substrate including a first surface and a second surface; a first pattern and a first outgoing wire that are formed on the first surface of the substrate, where the first pattern covers a partial area of the first surface of the substrate, and the first outgoing wire is formed in a remaining area, except the first pattern, of the first surface of the substrate; and a second pattern and a second outgoing wire that are formed on the second surface of the substrate, where the second pattern covers a partial area of the second surface of the substrate, and the second outgoing wire is formed in a remaining area, except the second pattern, of the second surface of the substrate. The first surface and the second surface are two opposite surfaces of the substrate. A perpendicular projection, on the first surface, of the second pattern covers at least the remaining area, except the first pattern, on the first surface.

Description

Technical field [0001] The 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 has occupied a dominant position in smart portable devices. Such as figure 1 As shown, the capacitive sensor device of the touch screen above the liquid crystal display 7 (LCD, Liquid Crystal Display) is coated with a layer of transparent conductive material, such as indium tin oxide (ITO, Indium Tin Oxide) material, on the substrate 6, According to the requirements of the touch integrated circuit (IC, Integrated Circuit,), the corresponding conductive pattern is etched, and the ITO material is usually used, that is, the 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 transparent ITO in the hor...

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 frame area outside the touch screen area of ​​the fuselage for outgoing wires, which leads to the problem that the frame 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
