DISPLAY DEVICE AND METHOD FOR MANUFACTURING SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 18388058 titled 'DISPLAY DEVICE AND METHOD FOR MANUFACTURING SAME
Simplified Explanation
The patent application describes a display device with a backlight unit that includes a Light Emitting Diode (LED) surrounded by a refractive cover. The refractive cover has three surfaces: a first refractive surface, a second refractive surface, and a third refractive surface.
- The first refractive surface is positioned above the LED on the substrate and is either parallel or slightly inclined from the LED's axis.
- The second refractive surface is a curved surface that increases in angle from the first refractive surface towards the LED's axis.
- The third refractive surface is perpendicular to the LED's axis and connected to the second refractive surface.
Potential applications of this technology:
- LCD displays
- LED TVs
- Computer monitors
- Mobile devices
Problems solved by this technology:
- Improved light distribution
- Enhanced brightness and clarity
- Reduction of glare and reflection
Benefits of this technology:
- Better image quality
- Energy efficiency
- Longer lifespan of the display device
Original Abstract Submitted
A display device includes a backlight unit including: a substrate; a Light Emitting Diode (LED) disposed on a surface of the substrate; and a refractive cover configured to surround the LED. The refractive cover includes: a first refractive surface to: be spaced apart from the LED by a preset distance, be positioned on the upper surface of the substrate, be parallel to an axis of the LED or be inclined within one angle from the axis of the LED; a second refractive surface to be a curved surface in which an angle between a tangent line and the axis of the LED increases from a region connected to another upper portion of the first refractive surface toward a direction of the axis of the LED; and a third refractive surface to be connected to an portion of the second refractive surface and be perpendicular to the axis of the LED.
