Abstract: A display device is provided with a backlight module, a lower polarizing plate, a liquid crystal display panel, and an upper polarizing plate. In the display device of the present disclosure, when MicroLED luminescent units are turned on, a normal display is realized within a transparent display area. At the same time, images are collected through the transparent display area anytime and then sensed by an under-screen sensor. The transparent display area and the main display area are seamlessly connected so that there is no visual display interruption and discontinuous boundary, and a complete full-screen design is achieved.

Abstract: The present invention provides a display device which includes a display panel, a light shielding member, and an electronic element. The display panel includes a first display region and a second display region disposed corresponding to the electronic element, and a light transmittance of the second display region is greater than a light transmittance of the first display region. When the electronic element is in operation, the light shielding member is opened to open a light-transmitting channel between the electronic element and the second display region. When the electronic element is not in operation, the light shielding member is closed to close the light-transmitting channel. When the electronic element needs to be used, the light shielding member is opened. When the electronic element is not needed, the light shielding member shield the electronic element to hide it.

Abstract: A liquid crystal display (LCD) device and an organic light-emitting diode (OLED) display device are disclosed. The LCD device includes a base substrate, a display module, and a liquid crystal lens layer. The display module includes a fingerprint recognition sensor. The OLED display device includes a base substrate, a fingerprint recognition sensor, a two-layered liquid crystal lens layer, and an OLED display. The liquid crystal lens layer is configured to be switchable between a non-lens state and a lens state. By adopting liquid crystal lenses with holes, utilization of reflected light reflected by a fingerprint can be improved and imaging quality can be optimized.
