Liquid crystal terminal equipment and fingerprint acquisition device

The utility model discloses a piece of liquid crystal terminal equipment and a fingerprint acquisition device. According to the utility model, an ultrathin fingerprint acquisition instrument of any size can be formed based on the pin-hole imaging principle, and the ultrathin fingerprint acquisition instrument can be further combined with a liquid crystal display screen to realize the fingerprint acquisition function. The liquid crystal terminal equipment comprises a liquid crystal display assembly. The liquid crystal display assembly is at least composed of a liquid crystal board and a backlight module. The backlight module at least comprises a reflector plate and a backboard. The reflector plate and/or the backboard is provided with one or more imaging holes. Photovoltaic conversion sensors are arranged at positions corresponding to the positions of the imaging holes. According to the utility model, by performing structure improvement on the liquid crystal display screen according to the pin-hole imaging principle, the liquid crystal display screen can be used in fingerprint acquisition for supporting the terminal equipment to complete operations, such as screen unlocking, account verification, etc., in which personal identity authentication is needed through fingerprint identification.
