Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices with non-quadrangular shapes face challenges in design due to the unnecessary widening of the bezel and limitations in shaping, particularly when using traditional matrix forms of gate and data lines.
Innovation Solution
The display device incorporates radially disposed data lines and strategically positioned gate and emission driving circuits within the display area, allowing for varied shapes and reducing bezel size by optimizing the arrangement of pixel circuits, gate lines, and organic light-emitting diodes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional matrix forms of gate lines and data lines are used in free-shape display devices, then the display can be manufactured with standard processes, but the bezel becomes unnecessarily widened and design flexibility is limited
Solution Approach 1:
The gate driver is divided into multiple gate driving circuits that are distributed and disposed within the display area rather than concentrated in a single location. This segmentation allows the display to accommodate free shapes by placing driving circuits in non-overlapping areas throughout the display region, eliminating the need for a widened bezel while maintaining manufacturability.
Solution Approach 2:
The patent transitions from a traditional peripheral arrangement of driving circuits (requiring bezel space) to a distributed two-dimensional arrangement within the display area itself. By utilizing the display area in multiple dimensions and positions, the design achieves flexibility for various shapes without sacrificing ease of manufacture.
2Shape
If gate driving circuits are disposed outside the display area in a bezel, then the pixel circuits can be arranged in a regular matrix, but the bezel size increases unnecessarily
Solution Approach 1:
The gate driving circuits are extracted from the traditional peripheral bezel location and repositioned within the display area itself. This extraction eliminates the need for a widened bezel while the circuits continue to function independently, maintaining regular pixel circuit arrangements without increasing stationary object area.
Solution Approach 2:
The display area serves multiple functions: it displays pixel circuits for image output and simultaneously accommodates gate driving circuits for signal generation. This multi-functionality allows the same physical space to serve both display and driving purposes, eliminating the need for separate bezel space.
3Adaptability or versatility
If the display area is optimized for various free shapes, then design flexibility improves, but the arrangement of gate lines and data lines becomes more complex
Solution Approach 1:
The gate driving circuits are placed in specific local areas within the display region where they do not overlap with pixel circuits. This local quality approach allows different regions of the display area to have different functions (pixel regions vs. driving circuit regions), enabling free shape designs while maintaining relatively simple line arrangements in each local zone.
