Liquid crystal display device for under-screen identification scheme
View Patent ↗The present invention provides a liquid crystal display (LCD) device for an under-screen identification scheme. The LCD device for the under-screen identification scheme comprises a liquid crystal module, a backlight module, an under-screen sensor, and a micro light emitting diode (LED) module. The liquid crystal module defines a liquid crystal module operable region and a digging region adjacent to the liquid crystal module operable region. Therefore, there is no display interruption and discontinuous boundaries in the vision, and can achieve a complete full-screen design.
