Problems solved by technology

The disadvantages of this method of bonding the display screen and the touch panel to realize the display and touch functions are that, first, the number of components in the process and the device is increased; The transmittance
The third is the bonding method of the display panel and the touch panel. When the area of ​​the display screen is large, it is easy to introduce air bubbles on the bonding surface of the two, which becomes a defective product, reduces the product yield, and ultimately affects the cost of the device.

Embodiment Construction

[0024] The present invention will be described in further detail below in conjunction with the accompanying drawings and the method for preparing the packaging cover plate provided with the touch function layer, which is an explanation of the present invention rather than a limitation.

[0025] see Figure 1 to Figure 4 , an OLED display device in which a touch panel is integrated with a display screen, comprising an anode substrate 7 and a packaging cover 1 bonded through a sealing frame 6, and a gate 8 sequentially arranged between the anode substrate 7 and the packaging cover 1 , gate insulating layer 9, source electrode 10, hole injection layer 11, hole transport layer 12, electron blocking layer 13, light emitting layer 14, hole blocking layer 15, electron transport layer 16, electron injection layer 17; light emitting layer The light emitted by 14 is emitted through one side of the packaging cover 1 and reaches the user's eyes.

[0026] In the present invention, a touch...

Abstract

The invention discloses a touch panel and display screen integrated OLED display device, which comprises an anode substrate and an encapsulation cover plate which are stuck and connected and functional layers which are arranged in turn between the anode substrate and the encapsulation cover plate, wherein the inner surface of the encapsulation cover plate of the display is provided with touch functional layers, and the touch functional layers comprise a first transparent electrode layer, a first transparent electric insulating layer, a second transparent electrode layer and a second transparent electric insulating layer which are arranged in turn on the inner surface of the encapsulation cover plate; and the first transparent electrode layer, the first electric insulating layer and the second transparent electrode layer form a flat capacitor array. The touch sensing functional layers are integrated on the encapsulation cover plate, so display and touch functions can be realized without sticking a touch module to the exterior of the display screen, and the structure of the device is more compact and favorable for reducing the appearance size and weight of the device.

Description

technical field [0001] The invention belongs to the technical field of flat panel display devices, and relates to an OLED display device integrated with a touch sensor. Background technique [0002] At present, there are more and more designs for setting touch panels on electronic devices such as mobile phones and tablet computers, and controlling the devices through touch sensing. Combining the touch panel with the display greatly facilitates the user's control of such electronic devices, realizes the user experience of what you see is what you get, and can also realize some functions that cannot be realized by the original control method. As a result, such electronic devices are becoming more and more popular and may soon become a mainstream control method on small mobile devices. [0003] OLED is a new type of display device that has been developed rapidly recently. It has many advantages such as fast response speed, self-luminescence, all-solid structure, and thin thick...
