Problems solved by technology

[0004] Usually the display and the touch screen are made separately, and finally the touch screen is fixed on the top or the front of the display. The defect of doing this is: the thickness of the entire display device is increased; since the display and the touch screen are two separate devices, there will be Repeated film layers, unnecessary waste of cost; the touch screen has a certain absorption effect on light, and the gap between the touch layer and the display also increases the loss of light, thus reducing the brightness of the display

Abstract

The invention relates to an optical organic film structure of a display device and a display device. A touch screen structure is arranged on the optical organic film structure, a conductive layer of the touch screen structure is deposited on the upper surface of the optical organic film, and the touch screen structure is Connect a conductive sense lead. The display device of the present invention adopts the optical organic film structure of the display device of the present invention, and is arranged on the outermost layer, and further includes a position detection module connected with the optical organic film structure of the display device through a detection line. The present invention enables the optical organic film structure of the display device to have a touch screen function, and there is no film layer with repeated functions. The thickness of the display device is reduced, the number of film layers is reduced, and the cost is reduced.

Description

technical field [0001] The invention relates to an optical organic film structure of a display device and the display device, in particular to an optical organic film structure of a display device with a touch screen function and a display device using the optical organic film structure of the display device. Background technique [0002] Touch sensors or touch screens are one of the common means for people to input commands to computers or other control devices in daily life and work, and the two main forms used are resistive or capacitive. A conventional resistive touch screen usually consists of a layer of glass as the base layer, the surface is coated with a transparent conductive layer, and then covered with a layer of hardened outer surface, smooth and scratch-resistant soft layer, and the inner surface of the soft layer is also coated with a layer of transparent conductive layer. layer, separated by an air gap or other non-conductive medium between the base layer and ...
