Display Panel Barrier Layer and Color Filter Aperture Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multi-view display panels require higher luminance backlights due to light blocking by barrier layers, leading to increased power consumption, which is undesirable for applications needing heat dissipation, such as in-car displays.
Innovation Solution
Optimizing the widths of openings in the barrier layer and black matrix structures in the color filter layer to maximize the product of their aperture ratios, allowing for efficient light transmission while minimizing overlap and crosstalk, and incorporating array metals to further enhance light utilization and reduce power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a barrier layer is used to achieve multiple views, then multiple view capability is improved, but light is blocked and requires higher luminance backlight, increasing power consumption
Solution Approach 1:
The patent optimizes the aperture ratio parameter of the barrier layer by adjusting the width of openings and the pitch between them. By changing these geometric parameters, the barrier layer allows more light to pass through while still maintaining multiple view capability, thereby reducing the required backlight luminance and power consumption
Solution Approach 2:
The patent introduces a color filter layer with black matrix structures that extend in the vertical dimension (thickness direction). These black matrix structures block light from reaching certain areas, creating multiple views through vertical dimension control while the barrier layer handles the horizontal dimension, achieving multiple views with reduced light blocking overall
2Use of energy by moving object
If the aperture ratio of the barrier layer is increased to reduce light blocking, then power consumption is reduced, but the multiple view capability may be compromised
Solution Approach 1:
The patent divides the light control function into two segments: the barrier layer handles the primary light transmission and multiple view direction control through its openings, while the color filter layer with black matrix structures handles secondary light blocking to enhance view separation. This segmentation allows each layer to be optimized independently for its specific function
Solution Approach 2:
The patent creates a composite structure combining the barrier layer with the color filter layer containing black matrix structures. This composite design integrates two different light control mechanisms working together, achieving both high aperture ratio for low power consumption and effective multiple view capability through the combined action of both layers
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution results in a display panel with elevated aperture ratios and reduced power consumption, effectively addressing the need for lower power usage in multi-view displays while maintaining effective light output.
Implementation Method 1
The openings of the barrier layer output the light within specified zones, thereby cooperate with other elements of the panel to generate multiple views
Implementation Method 2
the barrier layer would block a portion of the light
