Problems solved by technology

In the traditional technology, the touch screen sensor is pasted on the package cover outside the AMOLED, and then the cover glass (Cover Lens) is pasted on the touch screen sensor. Sometimes in order to enhance the strength of the Cover Lens, it is even necessary to use strengthened glass, which causes The overall thickness of the display device in the traditional technology is relatively large, the weight is large, and the cost is high. At the same time, there is a gap between the AMOLED screen and the touch screen, which will cause a technical problem of reduced readability and parallax.

Embodiment Construction

[0043] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0044] see figure 1 In one embodiment, a method for manufacturing an integrated touch AMOLED display device is provided, including:

[0045] Step 101, making a flexible substrate on a carrier.

[0046] Specifically, the carrier in this step may be a glass carrier. This step is specifically: coating a PI film (Polymide Film, polyimide film) on a glass carrier, and thermally baking the PI film (for example, heating in nitrogen, 160-280° C. for 3 to 4 hours) to form flexible substrate.

[0047] Step 102 , fabricating a touch screen sensor directly on the flexible substrate, or fabricating a first ...

Abstract

The invention discloses a method for producing an integrated touch control AMOLED display device. The method comprises: producing a flexible substrate on a carrier; directly producing a touch screen sensor on the flexible substrate or producing a first barrier layer on the flexible substrate and then producing the touch screen sensor on the first barrier layer; producing a second barrier layer on the touch screen sensor; producing a low temperature poly silicon thin film transistor (LTPS-TFT) layer; producing an OLED element layer on the LTPS-TFT layer; producing a packaging protective layer on the OLED element layer; producing a flexible rear cover on the packaging protective layer; and removing the carrier. The method may reduce the thickness of the cost of the integrated touch control AMOLED display device and eliminate parallax.

Description

technical field [0001] The invention relates to the technical field of semiconductor device preparation, in particular to an integrated touch AMOLED display device and a preparation method thereof. Background technique [0002] AMOLED (Active Matrix Organic Light Emitting Diode, Active Matrix Organic Light Emitting Diode) is recognized as a new generation of display panels. Compared with ordinary liquid crystal panels, it has the technical advantages of faster response speed, higher contrast ratio, and wider viewing angle. [0003] With the advancement of AMOLED technology, the application scenarios of AMOLED are becoming more and more extensive. For example, AMOLED displays are also used in smart mobile display terminals. Usually, smart mobile display terminals also need to integrate touch screen technology in order to facilitate the use and operation of users. Therefore, it is necessary to combine AMOLED display technology and touch technology in smart mobile display termi...
