Window Bezel Reduction via Chromatic Barcode Printing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display devices face challenges in minimizing the bezel area to enhance the display area and aesthetic appeal, as existing fabrication methods are insufficient in reducing the bezel region effectively.
Innovation Solution
A window structure with a base substrate, a light-blocking layer, and a printing layer is implemented, where the printing layer with a chromatic barcode pattern is disposed on the light-blocking layer, which is extended along the bezel region, allowing for a reduced bezel area and increased display area by utilizing a barcode pattern carved in an intaglio manner.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the bezel area is reduced to enhance display area, then the display area is improved, but the structural stability and light blocking performance deteriorate
Solution Approach 1:
The light-blocking layer is divided into multiple segments (first light-blocking layer, second light-blocking layer, third light-blocking layer) with different widths and positions. Each segment blocks light from specific angles, collectively providing comprehensive light blocking performance even with reduced bezel area.
Solution Approach 2:
Different regions of the light-blocking layer have different properties - the first light-blocking layer has greater width for strong light blocking, while subsequent layers have reduced widths. The printing layer is positioned specifically in regions where light blocking is less critical, maintaining overall performance while reducing material usage.
2Area of stationary object
If the bezel area is reduced to enhance display area, then the display area is improved, but the manufacturing complexity increases
Solution Approach 1:
The barcode pattern is integrated directly into the printing layer that is already part of the window structure. This combines the aesthetic function (printing) with the identification function (barcode) into a single layer, eliminating the need for separate barcode application processes.
Solution Approach 2:
The printing layer serves multiple functions: it provides aesthetic appearance, contains the barcode pattern for device identification, and works in conjunction with the light-blocking layer to maintain bezel performance. This multi-functionality reduces the need for additional specialized components.
3Shape
If a printing layer with barcode pattern is added to reduce bezel area, then the appearance quality is improved, but the number of layers and structural complexity increases
Solution Approach 1:
The barcode pattern is embedded within the printing layer rather than being a separate component. This merging of identification functionality into the aesthetic layer adds visual appeal and device identification capability without requiring additional structural layers.
Solution Approach 2:
The barcode pattern is nested within the printing layer structure. The intaglio barcode pattern is carved into the printing layer, creating a nested structure where the functional element (barcode) is contained within the aesthetic element (printing layer), maximizing space efficiency.

AI summary
A window including a base substrate, which includes a transmission region and a bezel region in a plan view and includes a front surface and a rear surface that are opposite to each other in a thickness direction, a light-blocking layer, which is disposed on the rear surface of the base substrate and is overlapped with the bezel region, and a printing layer, which is disposed on the light-blocking layer and has a target surface, in which a barcode pattern is formed. The printing layer may have a chromatic color, and a width of the printing layer may be less than a width of the light-blocking layer.
