Embodiment Construction

[0036] At present, traditional OLED displays can also be integrated with touch technology, please refer to figure 1 A schematic diagram of the cross-sectional structure of the OLED touch display device. As shown in the figure, the touch display device 10 is mainly composed of an OLED structure to achieve a display function. The structure includes a lower substrate 130, a top cover 110, an OLED device 120 and a sealing layer 150, wherein the OLED device 120 It is stacked above the lower substrate 130 , and the upper cover 110 is further disposed above the OLED device 120 and integrated with the lower substrate 130 through the sealing layer 150 . In order to allow the device 10 to have a touch function at the same time, a capacitive touch sensing layer 100 is formed on the upper cover 110. The capacitive touch sensing layer 100 is composed of a first transparent conductive layer 101, an insulating layer 102 , a second transparent conductive layer 103 and an insulating protectio...

Abstract

The invention discloses an organic light emitting display device with a touch screen function and a manufacturing method thereof. The organic light emitting display device comprises a touch screen sensing layer and an organic light emitting layer, wherein a sensing electrode and an organic light emitting electrode share a composite layer. A capacitance type touch control sensing layer comprises an insulating layer, a first transparent conducting layer and a first touch control sensing layer, and an OLED light emitting layer comprises an anode layer, an organic light emitting layer and a cathode layer. The composite layer combines the first touch control sensing layer of the capacitance type touch control sensing layer and the cathode layer of the OLED light emitting layer. The organic light emitting display device with the touch screen function enables the overall thickness to be lowered, the manufacturing program to be reduced, and the cost to be lowered.

Description

technical field [0001] The invention relates to an organic light-emitting display device integrating touch screen functions and a manufacturing method thereof. It belongs to the field of touch screen display. Background technique [0002] In recent years, with the rapid development of technology, flat panel displays and touch panels have been widely accepted by consumers, gradually replacing traditional CRT displays and physical key input devices. [0003] At present, liquid crystal displays are the mainstream of flat panel displays, but the use of liquid crystal displays is limited due to many problems in display characteristics. As a new display technology, the prospect of active matrix organic light-emitting display (AMOLED) technology is widely optimistic. Organic light-emitting displays do not require a backlight, and consist of a coating of organic materials and a glass substrate. When an electric current passes through them, the organic materials emit light. Compar...
