Abstract

The invention provides a fingerprint identification module for a liquid crystal display panel, an array substrate, a manufacturing method of the array substrate and the liquid crystal display panel. The fingerprint identification module comprises an optical fingerprint identification sensor; and an insulating layer, wherein the insulating layer is arranged on the photosensitive surface of the optical fingerprint identification sensor, the insulating layer is in contact with the liquid crystal in the liquid crystal display panel, and the refractive index of the insulating layer is greater thanthe abnormal refractive index of the liquid crystal. When the fingerprint identification module is used in the liquid crystal display panel, more light reflected at the finger pressing position can beemitted into the optical fingerprint identification sensor, so that the utilization rate of reflected light during fingerprint identification is high, the detection precision of the optical fingerprint identification sensor is high, and the fingerprint identification function is well achieved; meanwhile, the direction of light emitted from the liquid crystal display panel is changed, so that thelight which should be emitted into the black matrix is emitted out of the liquid crystal display panel, the transmittance of the liquid crystal display panel is high, and a display picture is good.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a fingerprint recognition module, an array substrate and a manufacturing method thereof, and a liquid crystal display panel. Background technique [0002] In related technologies, the optical fingerprint recognition technology realizes fingerprint recognition by identifying the difference in the intensity of light reflected by the finger into the optical fingerprint recognition sensor due to the different reflectivity of the ridges or valleys on the surface of the finger after the light is irradiated on the finger. identify. However, when it is directly applied to the liquid crystal display panel, due to the low light transmittance of the backlight module, most of the light reflected by the finger cannot enter the optical fingerprint recognition sensor, so the fingerprint recognition cannot be well realized. function. [0003] Therefore, the related technology of fingerprint i...
