Embodiment Construction
[0018] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0019] see figure 1 , the embodiment of the present invention provides a capacitive touch screen, including a touch panel assembly 1 and an ITO layer (not shown in the figure), the ITO layer is arranged on the inner side of the touch panel assembly 1, and several An ITO trace 2, each ITO trace 2 is electrically connected to the ITO layer, used to make the ITO layer electrically connected to the processing module (not shown in the figure), when the touch panel assembly 1 senses a change in current, the ITO can be changed Layer capacitance changes, and this capacitance change is transmitted to the p...

Abstract
The invention relates to a touch screen and provides a capacitive touch screen. The capacitive touch screen comprises a touchpad assembly and an ITO (indium tin oxide) layer, wherein the ITO layer is arranged on the inner side of the touchpad assembly, and a plurality of ITO cables electrically connected with the ITO layer are also arranged on the touchpad assembly, an ITO cabling area for mounting the ITO cables is respectively arranged at the top and the bottom of the front surface of the touchpad assembly, two opposite side faces of the touchpad assembly are set to be first mounting surfaces for mounting the ITO cables, and each first mounting surface is connected with the two ITO cabling areas. The invention further provides a terminal. The terminal comprises an outer frame and further comprises the capacitive touch screen, and the touchpad assembly is clamped in the outer frame. According to the capacitive touch screen, the ITO cables can be mounted on the ITO cabling areas and the first mounting surfaces, so that the fact that the ITO cables are arranged on two opposite sides of the front surface of the touchpad assembly is avoided, and a purpose that the touch screen adopts an ultra-narrow frame is realized. The terminal adopts the capacitive touch screen, so that a display area can be maximized when the frame size is the constant.
Description
technical field [0001] The present invention relates to a touch screen, in particular to a capacitive touch screen and a terminal using the capacitive touch screen. Background technique [0002] With the popularization and application of mobile terminals such as mobile phones and tablet computers, touch screen design has gradually become the mainstream of various electronic products. Traditional touch screens mostly use resistive touch screens. However, due to the high difficulty of multi-touch technology of resistive touch screens and the easy scratching of touch screens, resistive touch screens are gradually replaced by capacitive touch screens. [0003] With the promotion and application of capacitive touch screens, users have put forward higher requirements for touch screens, not only needing to write smoothly on them, but also reducing the frame of touch screens as much as possible to maximize the display area. However, since the current capacitive touch screen needs t...
