DISPLAY APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18195534 titled 'DISPLAY APPARATUS
Simplified Explanation
The patent application describes a display apparatus that includes a liquid crystal panel and a backlight unit. The backlight unit consists of a substrate, a light emitting diode (LED), a refractive cover, and a lens.
- The substrate extends along a first direction.
- The LED is placed on the substrate to emit light.
- A refractive cover is provided on the LED to refract the emitted light.
- A lens is placed on the substrate and the refractive cover.
- The lens has a bottom surface with a shorter length in the first direction compared to a longer length in a second direction perpendicular to the first direction.
Potential applications of this technology:
- LCD televisions and monitors
- Mobile devices such as smartphones and tablets
- Automotive displays
- Virtual reality and augmented reality headsets
Problems solved by this technology:
- Enhances the efficiency of light emission from the LED by using a refractive cover and lens.
- Provides a more uniform distribution of light across the liquid crystal panel.
- Reduces the thickness and weight of the display apparatus.
Benefits of this technology:
- Improved image quality with better brightness and color uniformity.
- Energy-efficient design with enhanced LED light emission.
- Thinner and lighter display devices for improved portability and aesthetics.
Original Abstract Submitted
Disclosed herein is a display apparatus. The display apparatus includes: a liquid crystal panel; and a backlight unit configured to emit light to the liquid crystal panel. The backlight unit includes: a substrate extending along a first direction; a light emitting diode provided on the substrate; a refractive cover provided on the light emitting diode to refract light emitted from the light emitting diode; and a lens provided on the substrate and the refractive cover, the lens comprising a bottom surface having a first length in the first direction that is less than a second length in a second direction perpendicular to the first direction.
