DISPLAY APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 17968500 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 and multiple light emitting diode (LED) groups placed on the substrate. Each LED group comprises a red, green, and blue LED, with each LED having a light emitting layer and a distributed Bragg reflector (DBR) on top. The reflectivities of the DBRs for the red, green, and blue LEDs are within the same range based on the incident angle of light.
- The display apparatus includes a liquid crystal panel and a backlight unit.
- The backlight unit consists of a substrate and multiple LED groups.
- Each LED group contains a red, green, and blue LED.
- Each LED has a light emitting layer and a distributed Bragg reflector (DBR).
- The reflectivities of the DBRs for the red, green, and blue LEDs are within the same range based on the incident angle of light.
Potential Applications
This technology can be applied in various display devices, such as:
- Televisions
- Computer monitors
- Mobile devices (smartphones, tablets)
- Gaming consoles
- Digital signage
Problems Solved
The patent addresses the following problems:
- Uneven color reproduction in displays due to variations in reflectivity.
- Inconsistent brightness levels across different colors.
- Limited viewing angles resulting in color distortion.
- Inefficient use of backlighting, leading to higher energy consumption.
Benefits
The technology offers the following benefits:
- Improved color accuracy and uniformity in displays.
- Consistent brightness levels across different colors.
- Enhanced viewing angles with reduced color distortion.
- Energy-efficient backlighting, resulting in lower power consumption.
Original Abstract Submitted
A display apparatus includes a liquid crystal panel; and a backlight unit configured to provide light to the liquid crystal panel, wherein the backlight unit includes: a substrate; and a plurality of light emitting diode groups provided on an upper surface of the substrate, wherein each of the plurality of light emitting diode groups includes a red light emitting diode, a green light emitting diode, and a blue light emitting diode, wherein each of the red light emitting diode, the green light emitting diode, and the blue light emitting diode includes: a light emitting layer; and a distributed Bragg reflector (DBR) provided on the light emitting layer, and wherein reflectivities of the distributed Bragg reflectors of the red light emitting diode, the green light emitting diode, and the blue light emitting diode are within a same range of reflectivity according to an incident angle of light incident on the distributed Bragg reflectors.
