Abstract: A fingerprint and palmprint image collector with a honeycomb structure and a terminal device are provided. The image collector includes a light guide plate, and a light source for emitting at least part of light into the light guide plate. A surface of the light guide plate is provided with a honeycomb plate. A plurality of vias parallel to each other are densely disposed on the honeycomb plate. The diameter of each via is in a range from 0.5 micrometer to 50 micrometers, and the size of an acquired fingerprint or palmprint is equal to the size of an acquired image. The thickness of the honeycomb plate is more than five times of the diameter of the via. The distance between centers of adjacent vias is less than or equal to 50.8 micrometers. The other surface of the honeycomb plate is provided with an image sensor. The image collector can be integrated into the terminal device.

Abstract: An image acquisition apparatus, a terminal device, a liquid crystal terminal device and an image acquisition method are provided according to the disclosure. The image acquisition apparatus includes an imaging plate and an image sensor disposed to be spaced apart from one side of the imaging plate. The imaging plate is provided with an imaging pinhole corresponding to the image sensor. The liquid crystal terminal device includes an LCD panel and a backlight element. The image acquisition apparatus is disposed at a position corresponding to the LCD panel within the backlight element. The image acquisition method includes acquiring an image of an object to being scanned by the image sensor through the imaging pinhole at a side of the imaging panel. An ultrathin fingerprint scanner can be formed based on pinhole imaging principle in the disclosure, and can be further combined with an LCD screen to accomplish fingerprint acquisition function.
