Display Device Driver Overlap and Diagonal Light Shielding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In signage display devices, the frames around display devices create visual divisions and obstruct the display image, limiting the display quality due to the presence of light-shielding films and other components, necessitating a reduction in frame size to enhance image clarity and seamless integration of multiple displays.
Innovation Solution
The configuration of display devices includes a driver, pixel circuits, and relay lines that allow pixel electrodes to overlap the driver and light-shielding portions, with a relay line system that connects pixel circuits and electrodes efficiently, enabling a more compact design and improved display quality by minimizing the non-display areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a frame light-shielding film is provided in the frame area to shade drivers and dummy electrodes, then the reliability of the display device is improved by preventing light leakage, but the frame width increases creating visual divisions and obstructing the display image
Solution Approach 1:
The light-shielding function is extracted from the frame area and relocated to the non-display area. The frame light-shielding film is positioned to overlap the drivers and dummy electrodes in the non-display area, separating the light-shielding function from the frame structure itself, thereby reducing frame width while maintaining light shielding effectiveness.
Solution Approach 2:
The light-shielding film is arranged in a diagonal direction extending from the display area toward the corner of the non-display area, rather than following the conventional horizontal/vertical frame orientation. This diagonal arrangement allows the light-shielding film to cover the necessary areas while minimizing its projection into the frame area, thus reducing perceived frame width.
2Illumination intensity
If the frame width is reduced to improve display quality and seamless integration, then the visual obstructions are reduced, but the light shielding effectiveness may be compromised
Solution Approach 1:
A diagonal light-shielding film is introduced as an intermediary element that bridges the protection of drivers/dummy electrodes and the reduction of frame width. This film is positioned to overlap the non-display area components while extending diagonally, providing light shielding without requiring a wide horizontal frame, thus maintaining display clarity while protecting sensitive components.
