Embodiment 1

[0037] In the first embodiment, the signal pin is formed by a conductive layer disposed on the protection layer. The difference from Embodiment 1 is that in Embodiment 2, the signal pin 262 is a structure in the same layer as the cathode 261 , that is, a structure formed in the same process step. The OLED display device with a built-in touch control structure provided by Embodiment 2 is compatible with the process steps of forming the touch signal transmission line 213 and the signal pin 262 on the side of the array substrate 20 and the process step of forming the display A, that is, the signal pin The structures in the area C and the structures in the display area A are formed in the same process steps. When the touch structure is embedded in the OLED display device, and the touch signal transmission structure is arranged inside the OLED display device, the array No new steps are added to the substrate 20, and the production cost will not be increased.

Embodiment 3

[0047] In the OLED display device with a built-in touch control structure provided in Embodiment 3, the conductive structure 27 is arranged on one side of the array substrate 20, the non-conductive support 271 and the in-plane support 28 are formed in the same process step, and the conductive layer 272 Formed in the same process step as the cathode 261 , while the driving lines, sensing lines and touch signal transmission structures are arranged inside the OLED display device, the array substrate does not add new steps and does not increase production costs.

Abstract

The invention provides an OLED display device with a built-in touch control structure. The OLED display device comprises a cover plate and an array substrate which are oppositely arranged, and organic luminescence which is arranged in the internal side of the cover plate and the array substrate. The internal side of the cover plate is provided with multiple driving lines and multiple sensing lines. The internal side of the array substrate is provided with multiple signal pins which are corresponding to the multiple driving lines and the multiple sensing lines. Multiple conduction structures are arranged among the multiple driving lines, the multiple sensing lines and the multiple signal pins. The multiple driving lines, multiple scanning lines and the multiple signal pins are electrically connected respectively by one end of each of the multiple conduction structures. The other end of each of the multiple conduction structures is electrically connected with corresponding touch control signal transmission lines respectively.

Description

technical field [0001] The invention relates to the field of OLED display technology, in particular to an OLED display device with a built-in touch control structure. Background technique [0002] The organic light emitting diode (Organic Light Emitting Diode, OLED) display technology uses an organic material coating, which has the characteristic of self-luminescence. The OLED display screen has a large viewing angle and saves power, and has been widely used. With the development of touch technology, most portable display devices are equipped with a touch structure, so that users can directly operate it with a touch pen or fingers. [0003] However, in the prior art, the OLED display device plus a touch panel is generally realized through the process of attaching a touch panel on the outside of the OLED display device, and the device with an external touch panel has a large thickness and a touch structure. Vulnerable to damage and many other issues. Contents of the inven...
