Display System Luminance Segmentation for Emphasis Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display systems face complexity in adjusting luminance to effectively emphasize certain information while allowing user-preferred brightness settings, often resulting in inadequate emphasis of critical information due to cumbersome control mechanisms.
Innovation Solution
A display system comprising a liquid crystal element, a backlight, an adjustment unit, a light source control unit, and a liquid crystal control unit, where the light source luminance and liquid crystal tone levels are adjustable to maintain emphasis luminance greater than or equal to normal luminance levels, even as overall screen luminance adjusts, ensuring critical information is prominently displayed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the luminance of the backlight and the tone of the display element are adjusted for each mode to provide desired visible luminance, then the visible luminance can be adjusted based on user preference, but the display control becomes complicated
Solution Approach 1:
The patent segments the display area into normal information regions and emphasis information regions, allowing independent control of luminance for each segment. This enables different luminance levels to be applied to different parts of the display simultaneously, achieving both user preference adaptation and effective emphasis without requiring complex overall control mechanisms.
Solution Approach 2:
The patent applies local quality by allowing the emphasis information region to have a fixed higher luminance level while the normal information region adjusts according to user preferences. This local differentiation ensures that critical information remains prominently visible regardless of the overall display brightness setting, resolving the contradiction between adaptability and control complexity.
2Adaptability or versatility
If the luminance of the backlight is adjusted to change visible luminance, then the overall brightness can be adapted, but the emphasis display of critical information may be compromised
Solution Approach 1:
The patent divides the backlight control into separate segments corresponding to normal and emphasis information regions. The emphasis region receives dedicated backlight control that maintains high luminance independently of the overall backlight adjustment, ensuring that critical information remains visually prominent even when the user lowers the overall display brightness.
Solution Approach 2:
The patent implements local quality by applying different luminance characteristics to different regions of the display. The emphasis information region maintains a fixed higher luminance level that is independent of the user-adjustable brightness settings applied to the normal information region, thereby preserving emphasis effectiveness while allowing overall brightness adaptation.
3Ease of operation
If the tone of the display element is adjusted to modify visible luminance, then the display can be customized for user preference, but the emphasis information visibility may be reduced
Solution Approach 1:
The patent segments the display element control into separate tone adjustment mechanisms for normal and emphasis information regions. The emphasis region's tone is controlled independently to maintain sufficient contrast and visibility, while the normal region tone is adjusted according to user preferences, preventing loss of emphasis information visibility during customization.
Solution Approach 2:
The patent applies local quality by allowing different tone characteristics in different regions of the display element. The emphasis information region maintains a tone setting that ensures high visibility and contrast, while the normal information region tone is freely adjustable according to user preference, thereby preventing the loss of emphasis information visibility during user customization.

AI summary
A display system that includes a liquid crystal element, a backlight, an adjustment unit, a light source control unit, and a liquid crystal control unit. The light source control unit operates the backlight to change a light source luminance level of light. The liquid crystal control unit operates a first plurality of pixels of the liquid crystal element to display normal information with a normal tone level. The liquid crystal control unit operates a second plurality of pixels of the liquid crystal element to display emphasis information with an emphasis tone level. When an adjustment value changes within a predetermined changeable range, the luminance level gradually changes with a change of the adjustment value, the normal tone level gradually changes with the change of the adjustment value, and simultaneously the emphasis tone level is maintained to correspond to brightness equal to or greater than brightness of the normal tone level.
