Grid Dimming Film Control for Smoother Display Transitions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display systems face challenges in improving display performance by effectively managing external light transmission and attenuation to enhance image visibility.
Innovation Solution
A dimming device with a dimming film and controller that adjusts dimming states in a two-dimensional grid pattern, allowing for dynamic control of light transmission and attenuation based on user inputs, and temporarily switching grids between on and off states to align with display changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the dimming film and display device change patterns simultaneously, then the system maintains synchronized operation, but the noticeable difference in response speed between the dimming film and display device becomes apparent, causing user discomfort
Solution Approach 1:
The controller temporarily sets at least some grids to a dimming off state before changing the pattern of the two or more grids. This preliminary action allows the dimming film to prepare for the upcoming pattern change, reducing the noticeable difference in response speed between the dimming film and display device during transitions.
2Manufacturing precision
If the dimming film uses a grid structure for control, then the dimming pattern can be precisely adjusted, but the resolution difference between the grid-based dimming film and the display device becomes noticeable
Solution Approach 1:
The controller temporarily sets at least some grids to a dimming off state during pattern transitions. This partial action smooths out the visual appearance of individual grid boundaries by creating a temporary uniform state, thereby reducing the noticeable resolution difference between the grid-based dimming film and the display device.
3Productivity
If the controller changes the dimming pattern directly without temporary adjustment, then the operation is simple and fast, but the image transition causes user discomfort
Solution Approach 1:
The controller performs a preliminary step by temporarily setting at least some grids to a dimming off state before executing the pattern change. This preliminary action creates a smoother transition that reduces user discomfort during image changes, while the overall operation remains efficient due to the automated control sequence.
Data Source
AI summary
A dimming device according the present disclosure includes a dimming film, and a controller. In the dimming film, a plurality of grids are two-dimensionally arranged. In the memory, a program is stored. The controller is configured to set two or more grids among the plurality of grids to a dimming on state. The controller is configured to, when changing a pattern of the dimming on state according to a request, temporarily set at least some grids of the two or more grids to a dimming off state in middle of the changing.
