Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices, particularly those displaying 3D images, face significant crosstalk issues due to the insufficient response speed of electric optical active layers, leading to blurred and unclear images, especially in motion pictures.
Innovation Solution
A display device and method that utilize a display panel with optical effect layers and electrode sets, where the electrode sets sequentially affect different portions of the optical effect layer to create a moving light-blocking barrier section, minimizing crosstalk by controlling the transition region between frames.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the response speed of the electric optical active layer is increased, then crosstalk is reduced and image clarity is improved, but the manufacturing complexity and cost increase
Solution Approach 1:
The patent divides the optical effect layer into multiple independently controllable regions using multiple electrode sets. Each electrode set can be controlled separately to manage the transition timing in different areas, effectively segmenting the response control to reduce overall device complexity while improving response speed management.
Solution Approach 2:
The patent implements dynamic control of the optical effect layer by sequentially activating different electrode sets at different times. This dynamic approach allows the system to adapt the response timing of different regions, effectively managing crosstalk without requiring the entire layer to have uniformly high response speed, thus reducing manufacturing complexity.
2Reliability
If a light-blocking barrier is introduced to minimize crosstalk, then image clarity is improved, but the device structure becomes more complex
Solution Approach 1:
The patent uses the optical effect layer itself as an intermediary to create the light-blocking barrier effect. By controlling the optical properties of this existing layer through multiple electrode sets, the patent achieves crosstalk reduction without introducing separate physical barrier structures, thereby maintaining simpler device architecture.
3Reliability
If the transition region between frames is controlled more precisely, then crosstalk is minimized, but the control complexity increases
Solution Approach 1:
The patent segments the control of the transition region by dividing it into multiple zones controlled by different electrode sets. Each electrode set manages a specific temporal and spatial segment of the transition, allowing precise control of crosstalk without requiring complex centralized control of the entire frame transition.
Solution Approach 2:
The patent employs periodic sequential activation of electrode sets to control the transition region. By rhythmically activating electrodes in a predetermined sequence, the system achieves precise transition control through simple periodic control signals, reducing overall control complexity while maintaining effective crosstalk minimization.

AI summary
A display device includes a display panel configured to receive a first-frame image signal for displaying a first-frame image in a first frame. The display panel is further configured to receive a second-frame image signal for displaying a second-frame image in a second frame that immediately follows the first frame such that the display panel appears to display a transition region associated with a boundary between a portion of the first-frame image and a portion of the second-frame image and moving in a moving direction. The display device further includes an optical effect layer and electrode sets. The electrode sets respectively overlap different portions of the optical effect layer and are configured for sequentially starting affecting the different portions of the optical effect layer such that the optical effect layer appears to display a light-blocking section that moves in the moving direction and overlaps the transition region.
