The embodiment of the invention discloses a display device and fingerprint identification equipment, and relates to the technical field of display. The display device comprises a backlight module and a display panel, the backlight module comprises a back plate, an optical film layer, a function module and a switching device, the back plate is provided with an opening area, the function module is arranged in the opening area, and the switching device can control light emitted by a detection light source in the function module to reach the display panel. Reflection coatings are arranged on the sides, facing the display panel, of the back plate and the switching device. When the switching device is turned on, the function module emits detection light, and the detection light is reflected by fingers on the display panel and received by the function module. When the switching device is turned off, the reflecting coatings on the back plate and the switch device are connected into a whole, and the display device can be normally used. The fingerprint identification equipment comprises the display device and a control module, the function module in the display device is a fingerprint identification module, and the control module can control on or off of a switch. According to the embodiment of the invention, the problem that the application of an under-screen function module, especially a fingerprint identification technology, is difficult to use in an LCD display mode is solved, and the display effect and the use experience are considered at the same time.
Description
technical field [0001] The embodiments of the present application relate to the field of display technology, and more specifically, to a display device and a fingerprint identification device. Background technique [0002] Fingerprint identification technology has the advantages of high security and convenient and quick operation, and is widely used in electronic products. The realization of fingerprint imaging technology includes optical imaging, capacitive imaging, ultrasonic imaging and other imaging methods. Among them, optical fingerprint recognition technology has the characteristics of strong penetration ability and simple product structure design, and has gradually become the mainstream of fingerprint recognition technology. Current fingerprint recognition technology is mainly applied in electronic devices. [0003] When the optical fingerprint identification module is installed in the display screen, the normal situation is to install the fingerprint identification...
