Embodiment Construction

[0027] As shown in Figure 5, the upper substrate in the display device 53 is used as the lower substrate of the touch screen 51 at the same time, the outer surface of the upper substrate in the display device is plated with an indium oxide-tin ITO conductive layer 52, and the conductive layer Make electrodes on the ITO, as a working surface of the touch screen 51, the display device 53 and the touch screen 51 are integrated, and the conductive layer material can be selected from other materials that can form transparent electrode layers such as indium-zinc oxide (IZO). Other parts of the touch screen 51 are made by resistive or capacitive, see the specific embodiments of Fig. 6 and Fig. 7 .

[0028] The touch display screen shown in Figure 6 is one of the embodiments of the present invention, and it is made together by the integration of touch screen 6A and display screen 6B, and touch screen 6A adopts resistive type, and wherein substrate 66 has both been used as the upper sub...

Abstract

A display screen of touch type is prepared for using top base plate in display component also as bottom base plate of touch screen, plating conduction layer on external surface of top base plate in display component and arranging electrode used as an operation surface of touch screen on said conduction layer then integrating display component and touch screen to be an unified body.

Description

technical field [0001] The invention relates to a display screen and a manufacturing method thereof, in particular to a touch-type display screen and a manufacturing method thereof. Background technique [0002] At present, as an input device, the touch screen allows users to directly input information by touching or handwriting on the surface of the display device with a touch screen. It is more friendly and convenient than input devices such as mouse and keyboard, so it is more and more widely used in Various portable devices, such as mobile phones, PDAs, etc. The production of the touch screen display device in the prior art is mainly to assemble the separately produced touch screen finished product 11 and the finished display device 13 (as shown in FIG. 1 ), and they are generally connected by double-sided adhesive or optical glue 12 during assembly. , so that there is a gap or optical glue between the touch panel and the LCD screen, resulting in a decrease in transmitt...
