Window Panel Light-Blocking Layer for Display Boundary Definition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices face challenges in minimizing boundary recognition errors between the display area and non-display area, leading to imperfect image presentation.
Innovation Solution
A display device design featuring a window panel with decoration printed layers and a light-blocking layer, where the boundary between the display and non-display areas is defined by the inner surface of the light-blocking layer, and the pixel area is aligned geometrically with the display area using this boundary, with specific layer configurations and colors to enhance recognition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple window panel structure is used, then manufacturing complexity is reduced, but boundary recognition accuracy between display and non-display areas deteriorates
Solution Approach 1:
The patent applies a light-blocking printed layer with black color on the window panel to create a visually distinct boundary between the display area and non-display area. This color-based differentiation enables accurate boundary recognition without complicating the overall panel structure, directly resolving the contradiction between simplicity and recognition accuracy.
Solution Approach 2:
The light-blocking printed layer serves as an intermediary element that clearly demarcates the boundary between display and non-display areas. This intermediate layer with specific optical properties (light-blocking) provides a visual reference that improves boundary recognition accuracy while maintaining structural simplicity.
2Shape
If multiple decoration printed layers are added to improve appearance, then aesthetic quality is enhanced, but manufacturing complexity increases
Solution Approach 1:
The patent combines multiple functions into the window panel structure: the light-blocking printed layer simultaneously serves as a decorative element (providing aesthetic quality with black color) and a boundary definition element (enabling accurate boundary recognition). This merging of functions enhances appearance while avoiding the need for separate decorative components, thus controlling manufacturing complexity.
3Measurement precision
If the boundary line is defined by the inner surface of the light-blocking printed layer, then boundary recognition accuracy is improved, but manufacturing precision requirements increase
Solution Approach 1:
The light-blocking printed layer defines its own boundary (inner surface) that serves as the reference for alignment between the window panel and display panel. This self-defined boundary provides a clear visual and physical reference that improves boundary recognition accuracy while the adhesive layer accommodates minor positioning variations, reducing the stringency of manufacturing precision requirements.

AI summary
A display device includes a window panel including a display area and a non-display area including a first non-display area and a second non-display area and a display panel including a pixel area generating an image to be displayed in the display area and a non-pixel area surrounding the pixel area. The window panel includes a window glass, decoration printed layers disposed on the window glass in the first and second non-display areas, and a light-blocking printed layer disposed on the window glass and the decoration printed layers to cover the decoration printed layers in the first non-display area and having a black color. A boundary line corresponding to a boundary between the display area and the non-display area is an inner surface of the light-blocking printed layer and the display area corresponds to the pixel area at the boundary line.
