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.

Abstract: A mini light emitting diode (LED) backlight panel is provided, which includes a plurality of backlight sub-panels in a docking way. A light-filling region is disposed between the arbitrary adjacent two backlight sub-panels. Fluorescent powder or quantum dots are filled in the light-filling region. The mini LED backlight panel emits light to excite material of the light-filling region to emit light. Secondly, adopting design solutions of large and small light emitting angles in mixed arrangement on different heights of the light emitting surfaces in the mini LED backlight panel, improving brightness on the splicing position, thereby improving quality of light emitted from the mini LED backlight panel, and meanwhile is advantageous for an ultra-thin design of the backlight module.
