Problems solved by technology
The production process of the capacitive external touch panel in the prior art is relatively complicated, and it is necessary to form a touch-sensitive pattern on the conductive glass, and then use optical glue to bond the above-mentioned glass with the touch-sensitive pattern to the cover plate; At this time, air bubbles are easily formed between the two layers of materials, resulting in a low yield of the capacitive touch panel itself. In addition, there is a large error between the external touch panel and the LCD screen because it cannot be completely aligned.
In order to eliminate the adverse effects of displacement, the error caused by displacement must be compensated. For example, the user needs to perform software correction on the displaced capacitive touch screen, which also makes the application software complicated and inconvenient to use

The invention relates to a capacitive touch screen panel, which belongs to the technical field of display devices. The capacitive touch screen panel of the present invention includes first and second transparent substrates, and a liquid crystal layer; a plurality of pixel units and touch driving electrodes are arranged on the first transparent substrate, and the touch driving electrodes are electrically connected to the grid lines; Two transparent substrates are provided with touch sensing electrodes on the surface facing the liquid crystal layer, and a touch sensing layer is provided on the surface facing away from the liquid crystal layer; the touch sensing layer includes an ITO layer and an Ag layer arranged on the ITO layer; Comes with a transparent protective film. The capacitive touch screen panel of the present invention can not only realize ultra-thinning, but also eliminate the offset between the click position and the liquid crystal display position; the adhesion between the ITO film layer and the Ag layer is good, the sensitivity of the touch screen panel is improved and the The durability of the touch sensing layer is guaranteed, and the transparent protective layer not only has good wear resistance, but also has good oil resistance and fingerprint resistance.
Description
technical field [0001] The present invention relates to the technical field of display devices, and more specifically, the present invention relates to a capacitive touch screen panel. Background technique [0002] As a new input device, the touch screen is currently the simplest, most convenient and natural way of human-computer interaction; it endows multimedia with a new look and is an extremely attractive multimedia interactive device. At present, touch screens have been widely used in handheld devices such as mobile phones and pads. In addition, they are also widely used in business inquiries of public affairs and information inquiries on urban streets; Multimedia teaching and other fields. [0003] According to the composition and structure, touch screens can be divided into: plug-in touch screens, surface-covered touch screens, and built-in touch screens. Among them, the plug-in touch screen is produced separately from the touch screen and the LCD display, and then ...
