Anti-view Display Panel Reflective Layer Overlap
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current anti-view technologies in display devices reduce luminance efficiency due to the presence of anti-view sub-pixels, which interfere with normal display pixels, resulting in decreased brightness and efficiency.
Innovation Solution
A display panel design that includes a substrate with pixel units and an anti-view unit comprising a reflective layer, an anti-view light-emitting device, and an anti-view light-shielding layer, where the light-emitting layer of the anti-view device overlaps with the reflective layer, allowing for controlled light emission to enhance brightness and efficiency during anti-view displays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If anti-view sub-pixels are arranged in the display to interfere with normal display pixels, then anti-view functionality is achieved, but luminance efficiency is seriously reduced
Solution Approach 1:
The display panel segments the pixel structure into display pixels and anti-view pixels, with each serving distinct functions. The anti-view pixels are further segmented into reflective layers, light-emitting layers, and light-shielding layers, allowing independent control of anti-view and display functions to maintain luminance efficiency while achieving anti-view capability
Solution Approach 2:
Different regions of the anti-view pixel structure are assigned different optical properties: the reflective layer has high reflectivity, the light-emitting layer has specific emission characteristics, and the light-shielding layer has light-blocking properties. This local differentiation allows the anti-view function to be achieved without compromising the luminance efficiency of display pixels
2Reliability
If anti-view sub-pixels are arranged to interfere with display pixels, then anti-view capability is achieved, but display brightness is decreased
Solution Approach 1:
Instead of using light-absorbing or light-blocking materials traditionally, the patent uses a reflective layer that mirrors the structure of display pixels. This inverted approach allows the anti-view pixels to reflect light rather than absorb it, maintaining display brightness while achieving anti-view capability through structural interference
Solution Approach 2:
The anti-view pixel structure copies the basic organizational structure of display pixels but uses different material properties (reflective vs. emissive). This copying approach allows the anti-view function to be integrated without significantly altering the overall display brightness characteristics
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 effectively maintains high luminance efficiency while achieving anti-view functionality by controlling the light emission of the anti-view unit, ensuring that the display remains bright and readable from various angles, thus addressing the limitations of existing technologies.
Implementation Method 1
the orthographic projection of the light-emitting layer of the anti-view light-emitting device on the substrate overlaps at least partially with the orthographic projection of the reflective layer on the substrate
