Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display devices require separate driving units for each panel, leading to increased weight, size, and complexity, and often necessitate additional devices like glasses for stereoscopic viewing.
Innovation Solution
A display device configuration where two display panels are operated by a single driving unit, utilizing a driving signal with periodicity and a gamma voltage signal based on a linear gamma string, allowing for efficient image display and recognition of three-dimensional stereoscopic images without external aids.

Engineering Contradiction Analysis
1Reliability
If separate driving units are used for each display panel, then each panel can be independently controlled, but the weight, size, and complexity of the display device increase
Solution Approach 1:
The patent combines two separate driving units into a single integrated driving unit that can control both display panels. This merging reduces the overall weight and complexity while maintaining the capability to independently control each panel through separate driving signals generated by the unified driving unit.
Solution Approach 2:
The single driving unit is designed with multi-functionality to control both display panels independently. It generates separate driving signals for each panel and can operate them at different frequencies, effectively replacing multiple specialized driving units with one universal controller.
2Reliability
If separate driving units are used for each display panel, then each panel can be independently controlled, but the size and complexity of the display device increase
Solution Approach 1:
The patent merges multiple driving units into one integrated driving unit, reducing the number of components and simplifying the overall system architecture. This single unit handles control for both panels, reducing structural complexity while maintaining independent control through software or signal-level separation.
Solution Approach 2:
The driving unit is designed as a universal controller capable of managing multiple display panels with different requirements. It implements multi-functionality by generating different driving signals for each panel, including different frequencies and timing, within a single integrated system.
3Ease of operation
If conventional driving signals are used, then display panels can be operated, but stereoscopic image perception requires additional devices like glasses
Solution Approach 1:
The patent applies periodic action by driving the two display panels at different frequencies (e.g., one panel at 60Hz and the other at 120Hz). This frequency differentiation creates temporal separation in image display, enabling the human visual system to perceive stereoscopic images directly without requiring external optical devices like glasses.
Solution Approach 2:
The patent changes the driving frequency parameter of each display panel to achieve stereoscopic effect. By setting different refresh rates for the two panels and utilizing the persistence of vision, the system enables natural stereoscopic perception through parameter variation rather than through additional optical equipment.
