BACKLIGHT AND LIQUID CRYSTAL DISPLAY DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240255801 titled 'BACKLIGHT AND LIQUID CRYSTAL DISPLAY DEVICE

The abstract describes a backlight system with a prism sheet that has prisms on both surfaces, one facing the LEDs and the other facing away from them.

The prism sheet has a first prism on the surface facing the LEDs and a second prism on the opposite surface.
The first prism on the LED-facing surface has a first base and pitch, while the second prism on the opposite surface is scalene triangular in shape with a second base and angles.
The second base angle of the second prism is smaller than the first base angle of the first prism.
The length of the second base is smaller than the length of the first base.

Potential Applications: - This technology can be used in LCD displays to improve brightness and uniformity. - It can also be applied in automotive lighting for enhanced illumination.

Problems Solved: - Addresses issues with uneven lighting and glare in traditional backlight systems. - Improves light distribution and efficiency in various applications.

Benefits: - Enhanced brightness and uniformity in displays. - Reduced glare and improved energy efficiency. - Better overall performance and visual quality.

Commercial Applications: Title: Advanced Backlight System for Improved Display Performance This technology can be utilized in TVs, monitors, smartphones, and automotive displays to enhance visual quality and energy efficiency, catering to the consumer electronics and automotive industries.

Questions about the technology: 1. How does the prism sheet improve light distribution in the backlight system?

  The prism sheet redirects and diffuses light from the LEDs, resulting in more uniform illumination across the display.

2. What advantages does the scalene triangular shape of the second prism offer over traditional prism designs?

  The unique shape helps reduce glare and improve light efficiency compared to conventional prism configurations.
