Provided is a liquid-crystal display device including a display panel, a backlight module, and a fingerprint identification module. The display panel includes a display region. The display region includes a first display region and a second display region. The second display region also serves as a light sensing element region. The backlight module is configured to provide a backlight for the display panel and is provided with a via penetrating through the backlight module. The fingerprint identification module is disposed inside the via and includes a fingerprint identification sensor, a light plate, and a quantum dot film. The light plate is disposed between the fingerprint identification sensor and the quantum dot film. The quantum dot film is disposed between the light plate and the display panel. The quantum dot film includes at least one quantum dot set. The at least one quantum dot set includes infrared quantum dots.

Liquid-crystal display device

A light-emitting structure, a backlight module, a display module, and a display device are provided. The light-emitting structure includes a circuit substrate, including a first surface and a second surface sequentially arranged along a light-exiting direction of the light-emitting structure. The circuit substrate also includes a light-transparent substrate and a wiring structure located on a side of the light-transparent substrate in a thickness direction. The light-emitting structure also includes a plurality of light-emitting elements, arranged in an array on one of the first surface or the second surface of the circuit substrate. The plurality of the light-emitting elements is electrically connected to the wiring structure. The light-emitting structure also includes a heat sink, located on a side of the first surface of the circuit substrate. The heat sink is configured for dissipating heat generated by the plurality of the light-emitting elements.
