Displays with Direct-lit Backlight Units - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240272476 titled 'Displays with Direct-lit Backlight Units

The patent application describes a display with a pixel array, illuminated by a direct-lit backlight unit consisting of LED lights and various layers for light spreading and color conversion.

• Pixel array with liquid crystal pixels
• Direct-lit backlight unit with LED array on a printed circuit board
• Light spreading layers for uniform illumination
• Color conversion layer for improved color accuracy
• Brightness enhancement films for increased display brightness

Potential Applications: - High-quality displays for TVs, monitors, and mobile devices - Enhanced color accuracy for professional graphic design and photo editing - Improved brightness for outdoor digital signage

Problems Solved: - Uneven illumination in displays - Limited color accuracy in traditional displays - Low brightness levels in certain lighting conditions

Benefits: - Crisp and vibrant display quality - Accurate color reproduction - Enhanced visibility in various lighting environments

Commercial Applications: Title: Advanced Display Technology for Enhanced Visual Experience This technology can be used in the development of high-end displays for consumer electronics, professional monitors, and digital signage, catering to industries such as entertainment, advertising, and design.

Prior Art: Readers can explore prior patents related to display backlighting technology, LED arrays, and color conversion layers to understand the evolution of this innovation.

Frequently Updated Research: Stay updated on advancements in LED technology, color science, and display manufacturing processes to enhance the performance of this display technology.

Questions about Display Backlighting Technology: 1. How does the use of LED arrays improve display brightness and energy efficiency? LED arrays provide uniform illumination across the display, resulting in enhanced brightness levels while consuming less power compared to traditional backlighting methods.

2. What role do color conversion layers play in improving color accuracy in displays? Color conversion layers help to convert the light emitted by the LEDs into a wider range of colors, resulting in more accurate and vibrant color reproduction on the display.

Original Abstract Submitted

a display may have a pixel array such as a liquid crystal pixel array. the pixel array may be illuminated with backlight illumination from a direct-lit backlight unit. the backlight unit may include an array of light-emitting diodes on a printed circuit board. the backlight unit may include first, second, and third light spreading layers formed over the array of light-emitting diodes. a color conversion layer may be formed over the first, second, and third light spreading layers. first and second brightness enhancement films may be formed over the color conversion layer.
