Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional light grating films on LED display panels cause black images when viewed from the side at certain angles, affecting the overall image quality of splicing display panels due to high side view brightness.
Innovation Solution
A display panel design featuring a light grating layer with light gratings arranged at intervals along intersecting directions, integrated on the display panel main body to reduce side view brightness and thickness, allowing for a thinner panel structure that minimizes side visibility while maintaining visibility at larger viewing angles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a conventional light grating film is attached to an LED display panel, then side view brightness is reduced, but the display panel thickness increases and black images appear at certain viewing angles
Solution Approach 1:
The light grating layer is integrated directly onto the display panel main body, merging the light control function with the panel structure itself. This eliminates the need for separate attached films, thereby reducing overall thickness while maintaining the light control function.
Solution Approach 2:
The light gratings are arranged in a two-dimensional grid pattern with intervals along both first direction (horizontal) and second direction (vertical). This multi-directional arrangement controls light propagation in three-dimensional space, reducing side view brightness while preventing black images at specific angles through spatial distribution.
2Illumination intensity
If a conventional light grating film is attached to an LED display panel, then side view brightness is reduced, but black images appear at certain viewing angles affecting overall image quality
Solution Approach 1:
The light gratings are arranged in a two-dimensional grid pattern with intervals along both first direction (horizontal) and second direction (vertical). This multi-directional arrangement controls light propagation in three-dimensional space, reducing side view brightness while preventing black images at specific angles through spatial distribution.
Solution Approach 2:
The light grating layer uses different structures or parameters in different regions to optimize performance. By varying the light grating configuration locally, the patent maintains consistent image quality across different viewing angles while effectively reducing side view brightness.
3Illumination intensity
If light gratings are arranged densely to reduce side view brightness, then viewing angle is restricted, but visibility at larger viewing angles is maintained
Solution Approach 1:
The light gratings are arranged in a two-dimensional grid pattern with intervals along both first direction (horizontal) and second direction (vertical). This multi-directional arrangement controls light propagation in three-dimensional space, reducing side view brightness while preventing black images at specific angles through spatial distribution.
Solution Approach 2:
The light gratings are arranged at intervals rather than continuously, providing partial light control action. This intervalled arrangement is sufficient to reduce side view brightness to acceptable levels while preserving adequate viewing angle range, avoiding excessive restriction of light propagation.
