  • Patent number: 11747676
    Abstract: Disclosed is a display device. The display device achieves a slim bezel by forming a through hole at a bottom portion of a cover, and changing a connection structure of a sub-FPCB to be connected to a main FPCB such that the connection structure extends through the cover without extending along the outside of the cover. The display device achieves a reduction in the thickness of the display device and an enhancement in picture quality through change of an installation direction of an LED module constituted by a main FPCB and LED elements disposed at one surface of the main FPCB. The display device can reduce a space where a sensor unit is disposed in conventional cases by mounting the sensor unit on the LED module, and can realize an additional function such as skin care or sterilization in accordance with the kind of the sensor unit.
