Electronic Apparatus Hole Pattern Control for Light Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic apparatuses face challenges in efficiently managing hole patterns and hole lines to prevent external light interference and diffraction, particularly in regions surrounding electronic modules, which can lead to defects and reduced reliability.
Innovation Solution
The electronic apparatus incorporates a hole pattern control unit with transistors and a hole pattern design that is electrically insulated from hole lines, positioned closer to the base substrate than hole lines, and surrounded by the hole pattern, to minimize external light interference and enhance reliability.

1Object-affected harmful factors
If hole lines are positioned closer to the display region to improve light blocking, then light interference is reduced, but diffraction effects increase and reliability decreases
Solution Approach 1:
The patent divides the hole pattern structure into multiple components: a first hole pattern closer to the display region and a second hole pattern farther away, with hole lines positioned between them. This segmentation allows each component to perform its specific function - the first hole pattern blocks external light effectively, the hole lines maintain proper spacing to reduce diffraction, and the second hole pattern provides additional light blocking, collectively resolving the contradiction between light interference reduction and reliability maintenance.
Solution Approach 2:
The hole lines serve as an intermediary element positioned between the first hole pattern (closer to display region) and the second hole pattern (farther away). These hole lines act as a mediating structure that maintains appropriate spacing, preventing direct contact between the two hole patterns while still allowing both to function in blocking external light, thus reducing diffraction effects and maintaining display reliability.
2Reliability
If hole lines are electrically connected to improve conductivity, then electrical performance improves, but light interference and diffraction increase
Solution Approach 1:
The patent employs thin film insulation layers (first insulation layer and second insulation layer) that electrically isolate the hole lines from the hole patterns while maintaining optical transparency. These thin film structures allow the hole lines to be electrically connected for improved conductivity without directly contacting the hole patterns, thereby preventing light interference and diffraction while still achieving the desired electrical performance.
