Abstract

The invention provides an array substrate and a display panel. The array substrate comprises a substrate body, a thin film transistor layer and a fingerprint recognition assembly. According to the invention, the switching element and the fingerprint identification element of the fingerprint identification assembly are horizontally arranged in the thin film transistor layer, the fingerprint identification element and the switching element can be prepared together when the thin film transistor layer is prepared, the thickness of the panel can be reduced, and the structure is simple and not complex. Specifically, when the first semiconductor and the second semiconductor are prepared, after the corresponding patterns are patterned, phosphorane and borane gases can also be introduced to preparethe doped region together, and extra gas does not need to be introduced, so the cost is saved. Compared with a traditional LTPS manufacturing process, only the mask plate needed by the first P+ dopedregion and the mask plate of the photosensitive layer need to be added, and the manufacturing cost is low.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an array substrate and a display panel. Background technique [0002] Fingerprint identification technology has been widely used in small and medium-sized panels, mainly including capacitive, ultrasonic and optical methods. Compared with capacitive and ultrasonic fingerprint recognition technologies, optical fingerprint recognition has good stability, strong antistatic ability, good penetration ability and low cost. Optical fingerprint recognition technology uses the principle of refraction and reflection of light. When the light is irradiated on the finger, it is received by the photosensitive sensor after being reflected by the finger. After receiving the photosensitive sensor, the optical signal can be converted into an electrical signal for reading. Due to the different light reflections of fingerprint valleys and ridges, the reflected light intensity received by the sensor...
