Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display panels lack the ability to autonomously adjust to external environmental conditions, resulting in inadequate image visibility in varying light intensities, with issues of being too dark in sunlight and too bright in darkness.
Innovation Solution
A display panel comprising a substrate with a switch assembly made of indium gallium zinc oxide (IGZO) and a light-sensing assembly that automatically adjusts brightness and contrast based on external light intensity, utilizing a P-type, intrinsic, and N-type semiconductor layers, and a transparent conducting layer to regulate the display's settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional display panel is used, then manufacturing process is simple, but display panel cannot automatically adjust to external environment causing poor visibility in varying light conditions
Solution Approach 1:
The patent combines the light-sensing assembly with the switch assembly into an integrated structure, where the light-sensing assembly includes a P-type semiconductor layer, intrinsic semiconductor layer, and N-type semiconductor layer that work together with the IGZO-based switch assembly to automatically adjust display parameters based on ambient light conditions
Solution Approach 2:
The display panel is designed with multi-functionality by incorporating both display functions and light-sensing functions into a single device. The light-sensing assembly can detect ambient light intensity and automatically trigger brightness and contrast adjustments, eliminating the need for separate manual control mechanisms
2Illumination intensity
If display brightness is increased for dark environments, then visibility in darkness improves, but power consumption increases
Solution Approach 1:
The display panel implements dynamic brightness adjustment through the light-sensing assembly that continuously monitors ambient light conditions and automatically modifies display brightness and contrast parameters accordingly. This dynamic adaptation ensures optimal visibility while minimizing power consumption by adjusting brightness only when necessary
Solution Approach 2:
The light-sensing assembly provides feedback about ambient light intensity to the control system, which then adjusts the display parameters. This feedback mechanism enables automatic adaptation to environmental conditions, optimizing both visibility and energy efficiency by increasing brightness only when ambient light is insufficient
