Example

[0041] The third embodiment

[0042] When the other parts are the same as the first embodiment, the difference is that: instead of providing a polarizing layer, a retardation layer, and an optical compensation layer, an internal anti-reflection layer 20 is provided on the inner side of the sensing electrode layer; and there is no shielding layer. The electrode layer, but the distance between the first sensing electrode 6 and the second sensing electrode 7 is designed to be 0.25 mm, which plays a shielding role. By designing the distance between the first sensing electrode 6 and the second sensing electrode 7 to be 0.25 mm, the second sensing electrode 7 can be used as a shielding electrode layer, and the electrode support layer 16 can be used as a shielding insulating layer, which can shield most The interference from external signals at the bottom of the touch screen eliminates the need for additional shielding electrode layers and corresponding shielding insulating layers, whic...

Abstract

The invention relates to a capacitor touch screen, an electrode supporting layer, an adhering layer and an outer supporting layer of which are made of flexible material and form a mutually-clamped clamping structure so as to realize flexibility and bendability of the capacitor touch screen. Because all layers are made of the flexible material, the thickness of each layer can be freely set so as to achieve the purpose of thinness and free design of capacitor parameters; the outer supporting layer plays a role of covering and plays a role of supporting a first sensing electrode and a second sensing electrode, when the capacitor touch screen is bent, the outer supporting layer and the electrode supporting layer are correspondingly bent, the outer supporting layer and the electrode supportinglayer mutually interact to limit the deformation of the first sensing electrode and the second sensing electrode without easily generating breakage. Furthermore, the sensing electrode layer is arranged in the middle of the capacitor touch screen in the thickness direction to ensure that the first sensing electrode and the second sensing electrode are easily broken in a crossing part, thus the capacitor touch screen has higher reliability.

Description

technical field [0001] The invention relates to a touch sensing device, in particular to a capacitive touch screen. Background technique [0002] In recent years, with the rapid development and application of information technology, wireless mobile communications and information home appliances, people's dependence on electronic products is increasing day by day. In order to achieve more convenience, smaller size and more user-friendly, many information products have changed from traditional keyboards or mice as input devices to touch screens arranged in front of display screens as input devices. Existing touch screens can be roughly classified into capacitive, resistive, photosensitive and other types. Capacitive touch screens have been widely used in various electronic products, such as mobile phones, mp4, POS terminals and so on. The capacitive touch screen is characterized by high transmittance and no need to apply force when touching, and can resist harsh external env...
