Display Frame Light Guide for Brightness Uniformity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The placement of electronic components in display devices, such as camera modules, creates dark areas due to blocked light from side-entry sources, leading to uneven brightness and affected display effects.
Innovation Solution
A display panel design featuring a side light source and a frame around receiving holes, where the frame includes a light-facing portion and a backlight portion acting as a light guide to redirect light to the light-shielding region, improving brightness uniformity without additional structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a receiving hole is provided in the display screen to place electronic components, then the screen ratio is improved, but dark areas appear causing uneven brightness
Solution Approach 1:
The frame acts as an intermediary light guide structure between the side light source and the light-shielding region. It captures light from the side light source and redirects it to illuminate areas that would otherwise be dark, thereby resolving the brightness uniformity issue while maintaining the receiving hole for electronic components
Solution Approach 2:
The patent transitions from conventional top-entry or bottom-entry backlight designs to a side-entry light source configuration. This dimensional change in light entry allows the frame to function as a light guide around the receiving hole, effectively distributing light to previously dark areas without compromising screen ratio
2Illumination intensity
If a frame with light guide structure is added around the receiving hole, then brightness uniformity is improved, but device complexity increases
Solution Approach 1:
The frame serves multiple functions simultaneously: it provides structural support for the display assembly, acts as a light guide to improve brightness uniformity, and defines the receiving hole for electronic components. This multi-functionality reduces the need for additional dedicated light guide structures, thereby limiting the increase in device complexity
Solution Approach 2:
The patent merges the frame structure with the light guide function by integrating the light guide properties directly into the frame material or design. This consolidation eliminates the need for separate light guide components, maintaining structural simplicity while achieving improved brightness uniformity

Function Achieved in This Case
The solution enhances brightness uniformity and display effect by guiding light to previously dark areas, reducing panel thickness and manufacturing costs while maintaining a simple structure.
Implementation Method 1
the backlight portion is provided as a light guide to guide the lights emitted from the side light source toward the frame to the light-shielding region
Implementation Method 2
the backlight portion is provided as a light guide to guide the lights emitted from the side light source toward the frame to the light-shielding region

AI summary
The present application provides a display panel and a display device. The display panel includes a frame. The frame includes a light-facing portion and a backlight portion, wherein the backlight portion faces a light-shielding region and is provided as a light to guide the lights emitted from the side light source toward the frame to the light-shielding region. The backlight portion of the frame is provided as a light guide to guide the lights to the light-shielding region to improve the brightness of the light-shielding region on the display screen, so that the overall brightness of the display screen is more uniform and the display effect is improved.
