Problems solved by technology

[0003] At present, most AMOLED touch sensor sensors are located on the upper or lower surface of packaging glass, packaging film or circular polarizer, at least an additional layer of touch sensor sensor is required, and fingerprint recognition components need to be made on the back cover or front cover of the device. , when it is made on the front cover, it needs to open a hole or dig a groove, and it can only be identified in a specific area, which greatly limits the user experience

Abstract

The invention discloses an AMOLED display with integrated full-screen fingerprint identification and touch control. The AMOLED display comprises a touch control part, a fingerprint identification part and a TFT substrate. The surface of the TFT substrate is provided with an organic layer. The organic layer is provided with a transparent anode conductive Layer, a thin film encapsulation layer, a circular polarizer layer, an optical adhesive layer and a protective panel successively. The touch control part shares the transparent anode conductive layer with the fingerprint identification part. The transparent anode conductive layer is connected to a touch control and fingerprint identification integrated IC via a wire. The transparent anode conductive layer is an arrayed transparent anode pattern for simultaneously realizing touch control and full-screen fingerprint identification. The AMOLED display with integrated full-screen fingerprint identification and touch control uses In-cell technology, does not requires a layer of sensor, integrates a touch control IC and a fingerprint identification IC, achieves full-screen fingerprint recognition, and touch control and fingerprint recognition integration.

Description

Technical field [0001] The invention belongs to the technical field of touch display devices, and particularly relates to an AMOLED display integrating full-screen fingerprint recognition and touch control. Background technique [0002] Compared with traditional liquid crystal displays, AMOLED displays have the advantages of lighter and thinner, fast response speed, wide viewing angle, and ultra-high brightness. At the same time, lanthanide metal-doped IZO metal oxide TFTs are used to replace traditional a-Si. Low-temperature polysilicon (poly Si) TFTs. Among them, a-Si TFTs have low electron mobility and are difficult to meet high-resolution display. Low-temperature polysilicon TFTs have high electron mobility, but their large area uniformity is poor, the preparation process is complicated, and the cost is high . The metal oxide TFT has a high mobility: 5-50 cm2 / (V s), its manufacturing process is simple, the cost is low, and the large area uniformity is good. [0003] At presen...
