Transparent Display Diode Arrangement for White Balance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transparent display apparatuses face challenges in adjusting white balance due to differences in light flux between red, green, and blue light emitting diode elements, leading to inefficient use and increased heat generation.
Innovation Solution
A display apparatus design featuring a light source unit with a larger number of red light emitting diode elements compared to green and blue elements, arranged along a side surface of a light guide panel, where the light flux of red light is lower than that of green and blue, allowing for efficient use and adjustment of luminance without significant decrease in output.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the luminance of light emitting diode elements is adjusted to compensate for differences in light flux between colors, then white balance can be maintained, but heat generation increases and element efficiency decreases
Solution Approach 1:
The patent applies local quality by arranging a greater number of red light emitting diode elements (which have lower light flux) compared to green and blue elements (which have higher light flux). This non-uniform distribution compensates for the inherent differences in light output across colors, achieving white balance without requiring excessive luminance adjustment from individual elements, thereby reducing heat generation and improving efficiency.
2Illumination intensity
If the luminance of light emitting diode elements is increased to compensate for lower light flux, then the desired color output can be achieved, but the elements are used at values lower than rated power output reducing efficiency
Solution Approach 1:
The patent implements local quality by creating a non-uniform arrangement where red light emitting diode elements (with lower light flux characteristics) are present in greater numbers than green and blue elements. This allows the system to achieve balanced color output by relying on quantity rather than pushing individual elements beyond their efficient operating range, thereby maintaining high element efficiency.
3Device complexity
If a single module contains all three light emitting diode elements, then device complexity is reduced, but differences in chromaticity make efficient use difficult
Solution Approach 1:
The patent resolves the contradiction between simplified module structure and element efficiency by maintaining a single-module design while applying local quality through non-uniform arrangement of individual diode elements within that module. Specifically, red elements are arranged in greater numbers to compensate for their lower light flux, allowing the system to achieve efficient operation without requiring complex multi-module structures.
