Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing driving structures for display panels, such as mini LED or micro LED display panels, require scan lines, which increases the complexity of the display panel structure.
Innovation Solution
A driving structure for display panels that eliminates the need for scan lines by using a series-connected driving group with multiple drivers receiving input data at different times, allowing each driver to control a display component with unique pixel data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If scan lines are disposed on the display panel to drive display components, then the display panel can be driven using prior art driving structures, but the structure complexity of the display panel increases
Solution Approach 1:
The patent extracts and removes the scan lines from the display panel structure. By eliminating the scan lines entirely and using a different driving approach (serially connected drivers that receive data at different times), the invention maintains display functionality while removing the complex scan line infrastructure, thus reducing structure complexity while preserving adaptability to modern display panels
2Speed
If multiple drivers receive input data simultaneously to drive multiple display components, then the driving speed is fast, but scan lines are required which increases structure complexity
Solution Approach 1:
The patent implements periodic action by having multiple drivers receive input data at different times in a sequential manner. Each driver is activated at specific time intervals to receive and process data, then drives its corresponding display component. This time-division multiplexing approach maintains driving speed while eliminating the need for simultaneous data transmission through complex scan line structures
Solution Approach 2:
The patent transitions from spatial parallelism (multiple drivers receiving data simultaneously through spatially distributed scan lines) to temporal parallelism (multiple drivers receiving data sequentially at different times). By moving the differentiation from spatial dimension to temporal dimension, the invention achieves efficient multi-component driving without requiring the complex spatial infrastructure of scan lines
