Display Device Non-Transmitting Edge Shielding for Frame Concealment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In display devices with metal frames, positional shifts between the liquid crystal display panel and the display plate can cause the metal frame to be visually exposed, degrading the appearance and merchantability when viewed straight on.
Innovation Solution
A display device design featuring a light transmitting board with a non-transmitting part that overlaps with the peripheral edge of the display area, ensuring the frame body remains hidden by matching the color tone of the non-transmitting part with the pixels inside the peripheral edge, even if the display plate shifts during assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the display plate is joined with the liquid crystal display panel using a light transmitting spacer, then the display device can be assembled efficiently, but the position of the display plate may shift during assembly, causing the metal frame to be visually exposed and degrading appearance quality
Solution Approach 1:
The patent applies local quality by creating a non-transmitting part (light shielding layer) at the specific peripheral edge region of the display plate where the metal frame is located. This localized modification allows the majority of the display plate to remain transparent for viewing purposes while the specific edge region blocks light to conceal the metal frame, thus resolving the appearance issue without affecting overall assembly efficiency
Solution Approach 2:
The non-transmitting part acts as an intermediary element between the metal frame and the viewer. It mediates the visual conflict by blocking the unwanted view of the metal frame while maintaining the transparency needed for display functionality, thus solving the position alignment issue without requiring precise assembly
2Reliability
If the light shielding layer is formed to completely overlap with the metal frame, then the metal frame can be hidden, but any position shift causes the frame to be exposed through the visualization area, degrading merchantability
Solution Approach 1:
The patent applies preliminary action by extending the light shielding layer beyond the expected position of the metal frame into the display area. This anticipatory positioning ensures that even if the display plate shifts during assembly, the light shielding layer will still cover the metal frame, thus providing tolerance for position alignment variations without requiring high precision
Solution Approach 2:
The non-transmitting part is strategically positioned at the peripheral edge of the display area where it serves dual purposes: maintaining the overall transparency of the display plate while locally blocking the view of the metal frame. This localized approach allows the system to tolerate position shifts without exposing the frame
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration enhances merchantability by preventing the metal frame from being visually exposed, maintaining a consistent and appealing appearance regardless of minor positional shifts during assembly.
Implementation Method 1
a light transmitting spacer (a transparent resin) filled in a gap formed between the liquid crystal display panel and the display plate
Implementation Method 2
a frame-shaped light shielding layer which corresponds to a region outside the display area and which does not transmit light is formed

AI summary
Provided is a display device that can increase merchantability. The display device has a display means (30) having display elements (31), which provide a display area (R1) that can display prescribed information, and a display plate (14) that covers this display means (30) joined by a transparent resin (40) filled into a gap formed between the display means (30) and the display plate (14). The display plate (14) is provided with a light transmitting substrate (14b) used as a base material therefor and a non-transmitting part (14c) formed on the light transmitting substrate (14b) so as to cover a peripheral edge part (S1) of the display area (R1) when the display device is viewed straight on from the viewer side.
