Narrowing Display Frame Width via Circuit Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices with irregular shapes face challenges in narrowing the frame when two types of drive circuits are arranged, as previous methods only addressed single-type drive circuits.
Innovation Solution
A display device configuration where either scanning circuits or emission circuits are arranged on a second side, with wiring lines extending from these circuits to connect with scanning lines or light emission control lines at the corner portions, allowing for a narrower frame width.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If both scanning circuits and emission circuits are arranged in the corner portion of the display panel, then the drive circuit coverage is complete, but the frame width cannot be narrowed
Solution Approach 1:
The drive circuits are segmented into two types: scanning circuits and emission circuits. By dividing the drive circuit functionality into separate modules, the patent enables flexible arrangement where only one type of circuit is placed in the corner portion, while the other type is arranged on the side portions, thus narrowing the frame width while maintaining complete drive circuit coverage.
Solution Approach 2:
The patent transitions from a two-dimensional arrangement where both circuit types occupy the same corner space to a three-dimensional distribution across different spatial zones. Scanning circuits are arranged in corner portions while emission circuits are arranged on side portions (or vice versa), utilizing the frame's extended areas to reduce corner portion width.
2Length of stationary object
If only one type of drive circuit is arranged in the corner portion, then the frame width is narrowed, but the other drive circuit functionality must be extended through wiring
Solution Approach 1:
One type of drive circuit is extracted from the corner portion and relocated to the side portions of the frame. This extraction reduces the complexity of wiring in the corner portion, as only one type of circuit needs to be connected to the display region, while the other circuit type is positioned where it can directly interface with the display region without requiring extensive wiring extensions.
3Volume of moving object
If the display panel uses a regular rectangular shape, then the frame structure is simple, but the device size cannot be reduced for portable applications
Solution Approach 1:
The patent employs asymmetric arrangement of drive circuits within the frame structure. By placing scanning circuits and emission circuits in different spatial locations (corner portions versus side portions), the design accommodates irregular display panel shapes while maintaining systematic circuit organization, enabling size reduction for portable devices without compromising structural simplicity.

AI summary
To provide a display device including a display panel having an irregular shape capable of narrowing the frame even in a case where two types of drive circuits are arranged.In a display panel having an irregular shape including a frame formed from straight line regions and curved line regions, scanning circuits and emission circuits are separated. Then, the separated scanning circuits are arranged in a first corner portion, which is the curved line region of the display panel, while being shifted along an outer peripheral edge of a display region, and the emission circuits are arranged in a row on a second side, which is the straight line region.
