Display Apparatus Ambient Temperature Image Contrast Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional liquid crystal display technologies face challenges in improving image contrast due to limitations in backlight diffusion, leading to increased manufacturing costs and complexity.
Innovation Solution
A display apparatus with two panels and a controller that adjusts image data based on ambient temperature and brightness by dividing it into blocks or performing binary processes to generate adjusted image data, which is then used to drive the second display panel, thereby enhancing contrast and display quality.

Engineering Contradiction Analysis
1Illumination intensity
If light guide plates and complicated backlight module control mechanisms are adopted to increase the contrast of the image, then the contrast is improved, but the manufacturing cost is increased
Solution Approach 1:
The patent changes the control parameters from physical hardware modifications to software-based image processing parameters. By adjusting brightness and contrast parameters through image data processing, the system achieves improved image contrast without requiring additional light guide plates or complicated backlight control mechanisms, thereby avoiding increased manufacturing costs
Solution Approach 2:
The patent replaces the mechanical/optical system (light guide plates and backlight control mechanisms) with an information processing system (image data processing). Instead of physically controlling light distribution, the system processes image data to achieve contrast enhancement, substituting mechanical complexity with computational simplicity

Solution Approach 2:
The patent makes the existing display system perform multiple functions: it displays images while simultaneously processing image data to enhance contrast. The same display device handles both normal image rendering and contrast enhancement through software processing, eliminating the need for separate dedicated contrast control mechanisms
