Patent number: 11747676Abstract: 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.Type: GrantFiled: July 13, 2022Date of Patent: September 5, 2023Inventors: Ji-Soon Oh, Cheol-Woo Park, Yeoun-Jei Jung, Jung-Mok Lee, Keum-Young Oh

Patent number: 10627669Abstract: An optical film includes a prism part having a plurality of prism patterns obliquely arranged in rows on a multilayer-structured reflective polarizing part. The reflective polarizing part is configured to reflect light from a first polarization axis and transmit light through a second polarization axis perpendicular to the first polarization axis. The rows of the prism patterns are arranged at a predetermined angle of inclination relative to the second polarization axis to reduce a Moiré phenomenon. The optical film may be adopted in a liquid crystal display device including a backlight unit to transmit light to a liquid crystal panel. A first polarizing plate is disposed between the optical film and the liquid crystal panel, and has a transmission axis that coincides with the second polarization axis of the reflective polarizing part to maximize light transmission from the backlight unit to the liquid crystal display.Type: GrantFiled: August 30, 2016Date of Patent: April 21, 2020Assignee: LG Display Co., Ltd.Inventor: Yeoun-Jei Jung
