Abstract

The invention relates to a flexible touch display screen and belongs to the technical field of display devices. The flexible touch display screen of the present invention includes first and second transparent flexible substrates, and a liquid crystal layer; touch driving electrodes are arranged on the first transparent flexible substrate, and the touch driving electrodes are electrically connected to grid lines; Two transparent flexible 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 film layer and is arranged on the ITO film layer on top of the Ag metal layer. The flexible touch display screen of the present invention can not only achieve ultra-thinness, but also eliminate the offset between the click position and the liquid crystal display position; and the adhesion between the ITO film layer and the Ag layer is good, which improves the touch screen. The sensitivity of the panel also ensures the durability of the touch sensing layer. 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 flexible touch display screen. 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 ...
