DISPLAY APPARATUS AND LIGHT SOURCE DEVICE THEREOF WITH OPTICAL DOME - A simplified explanation of the abstract
This abstract first appeared for US patent application 18540999 titled 'DISPLAY APPARATUS AND LIGHT SOURCE DEVICE THEREOF WITH OPTICAL DOME
The patent application describes a display apparatus that includes a printed circuit board (PCB), a light emitting diode (LED) chip mounted on the PCB, an optical dome formed to enclose the LED chip, and a liquid crystal panel to control the light output from the LED chip.
- The display apparatus consists of a PCB, an LED chip, an optical dome, and a liquid crystal panel.
- The LED chip emits light, which is enclosed by the optical dome formed on top of it.
- The liquid crystal panel regulates the light output from the LED chip.
- The optical dome is designed to meet specific dimensional criteria to optimize light emission.
Potential Applications: This technology can be used in various display devices such as televisions, monitors, and digital signage.
Problems Solved: This technology addresses the need for efficient light emission and control in display devices.
Benefits: Improved brightness and color accuracy in display screens. Enhanced energy efficiency due to optimized light emission.
Commercial Applications: This technology can be applied in the consumer electronics industry for manufacturing high-quality display devices with superior performance.
Questions about the technology: 1. How does the optical dome impact the overall performance of the display apparatus? 2. What are the advantages of using liquid crystal panels in conjunction with LED chips in display devices?
Original Abstract Submitted
According to the disclosure, a display apparatus includes a printed circuit board (PCB), a light emitting diode (LED) chip mounted on the PCB and configured to emit light, an optical dome formed to enclose the LED chip by being dispensed on the LED chip, and a liquid crystal panel configured to block or pass light output from the LED chip, wherein the optical dome may be formed to satisfy 1.70<r1/r0<1.83 where r0 is a straight distance for light vertically emitted from the LED chip to reach a surface of the optical dome and r1 is a straight distance for maximum output light emitted from the LED chip to reach the surface of the optical dome.
