Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current OLED display technologies suffer from limited light emission flexibility and a small range of use scenarios due to light-emitting elements sharing a pixel circuit in the same row, leading to reduced resolution and flickering issues.
Innovation Solution
A display panel design where light-emitting elements in different rows share a pixel circuit and emit light in different time periods within a frame, allowing for flexible pixel arrangement modes and reducing flickering through staggered lighting techniques.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If light-emitting elements are arranged in the same row and share a pixel circuit, then device complexity is reduced, but display resolution deteriorates and flickering occurs
Solution Approach 1:
The patent transitions from horizontal arrangement (same row) to vertical arrangement (different rows) of light-emitting elements sharing a pixel circuit. This dimensional change allows multiple light-emitting elements to share one pixel circuit without reducing display resolution, as they are positioned at different vertical locations rather than occupying the same horizontal space.
Solution Approach 2:
The patent implements time-division multiplexing where light-emitting elements in different rows are driven alternately in different time periods within a frame. This periodic activation pattern reduces flickering by ensuring that not all shared light-emitting elements are on simultaneously, while still achieving the desired display resolution through sequential rendering.
2Ease of manufacture
If light-emitting elements share a pixel circuit in the same row, then ease of manufacture is improved, but adaptability of light emission patterns deteriorates
Solution Approach 1:
By arranging light-emitting elements in different rows rather than the same row, the patent enables diverse light emission patterns including column-based, row-based, and block-based arrangements. This spatial reconfiguration maintains manufacturing simplicity while significantly improving adaptability for various display modes and scenarios.
Solution Approach 2:
The patent introduces dynamic control where different groups of light-emitting elements are activated in different time periods based on display requirements. This temporal dynamics allows flexible adaptation to various use scenarios while maintaining a simple shared pixel circuit structure, enabling both static and dynamic display patterns.
3Productivity
If multiple light-emitting elements share a pixel circuit, then productivity increases, but harmful factors increase due to flickering
Solution Approach 1:
The patent employs periodic time-division multiplexing to control light-emitting elements in different rows at different time periods. This structured periodic activation prevents simultaneous operation of multiple shared light-emitting elements, thereby reducing flickering effects while maintaining high display efficiency through effective utilization of the shared pixel circuit resource.
Solution Approach 2:
The patent pre-organizes light-emitting elements into distinct row groups that can be activated in a predetermined sequence. This preliminary structuring allows the display system to systematically manage the activation of shared light-emitting elements, ensuring that flickering is minimized through planned temporal separation before actual display operation begins.
