Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display panels, mainly rectangular in shape, lack flexibility in design as they are fixed to either portrait or landscape orientations, limiting their adaptability to different video sources and display modes.
Innovation Solution
A pixel circuit design featuring a first and second switch circuit, driving circuit, and light-emitting elements with signal lines extending in orthogonal directions, allowing for the transmission of both gate scanning and data signals, enabling the display panel to switch between portrait and landscape modes, thereby increasing design flexibility and adaptability to various video sources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display panel uses a fixed rectangular design with dedicated portrait or landscape orientation, then the manufacturing process is simplified and production is easier, but the adaptability to different video sources and display modes is reduced
Solution Approach 1:
The patent makes the gate lines and data lines universally functional by enabling them to transmit both gate scanning signals and data signals. Specifically, first gate lines can transmit data signals and second data lines can transmit gate scanning signals, allowing the same physical lines to serve multiple functions depending on the display orientation, thus achieving multi-functionality without increasing physical line quantity
Solution Approach 2:
The patent introduces dynamic configurability to the display panel through controllable switch circuits that can dynamically change the function assignment of circuit lines based on the required display orientation. The switch circuits enable the system to adapt between portrait and landscape modes by dynamically routing signals through appropriate paths, making the panel flexible rather than fixed
2Adaptability or versatility
If the display panel is designed for a single orientation (portrait or landscape), then the circuit line arrangement is simpler and manufacturing precision is easier to maintain, but the freedom and flexibility of production design are reduced
Solution Approach 1:
The patent employs asymmetric routing strategies where first gate lines and second data lines extend along a first direction while second gate lines and first data lines extend along a second direction. This asymmetric yet systematic arrangement allows the same physical infrastructure to support multiple orientations by changing signal routing logic rather than physical layout, maintaining manufacturing precision while increasing design freedom
3Ease of manufacture
If the display panel uses separate dedicated lines for gate scanning and data signals in each orientation, then signal transmission is more reliable, but the manufacturing complexity and cost increase
Solution Approach 1:
The patent merges the functions of gate lines and data lines by enabling each type of line to carry both gate scanning signals and data signals through the use of controllable switch circuits. This consolidation reduces the total number of physical lines required while maintaining reliable signal transmission through proper signal routing control, thereby simplifying manufacturing without compromising reliability
