Polarizer-Guide Panel Display Structure for Slim Bezels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices face challenges with increased cost, weight, and thickness due to the use of cover glass, and light leakage issues at the top of the guide panel, which affect the aesthetic design.
Innovation Solution
The use of a polarizer or optical film instead of cover glass, combined with a light shielding layer and foam pad, to minimize the width of the front edge and block light leakage, while enhancing adhesive strength and shock resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cover glass is used in the display device, then the display device has improved protection and durability, but the cost, weight, and thickness increase
Solution Approach 1:
The patent removes the cover glass component from the display device structure, extracting the protective function to alternative components such as the extended polarizer and guide panel, thereby reducing thickness while maintaining protection
Solution Approach 2:
The polarizer is extended beyond the display panel boundaries to serve multiple functions: it acts as both an optical component for the display and a protective/structural element that replaces the traditional cover glass function, reducing the need for separate protective components
2Shape
If the width of the front edge is reduced to improve aesthetics, then the design is improved, but light leakage toward the top of the guide panel occurs
Solution Approach 1:
The solution addresses the light leakage problem not by widening the front edge horizontally, but by extending the polarizer vertically beyond the guide panel top surface, using the vertical dimension to block light leakage paths while maintaining the narrow horizontal bezel for aesthetic purposes
Solution Approach 2:
The extended polarizer acts as an intermediary element that blocks light leakage paths between the guide panel and the external environment, preventing harmful light from reaching areas it should not while maintaining the desired narrow front edge design
3Length of moving object
If a film such as polarizer or optical film is used instead of cover glass, then the thickness is reduced for slim design, but the adhesive strength and shock resistance may be compromised
Solution Approach 1:
The patent combines the polarizer with the guide panel structure by extending the polarizer to the top surface of the guide panel and removing the step, merging these components into an integrated structure that maintains strength while achieving slim design
Solution Approach 2:
The solution creates a composite structure where the polarizer film is integrated with the guide panel and foam pad, combining materials with different properties to achieve both the slim profile of a film-based design and the structural strength of the rigid guide panel

AI summary
A display device can include a polarizer disposed on an uppermost layer of the display device; a display panel having a upper surface attached to the polarizer; a light shielding layer formed on an edge of a rear surface of the polarizer; a bottom cover disposed under the display panel and accommodating the display panel; and a guide panel disposed on a rear surface and a side surface of the display panel. The guide panel includes a horizontal portion and a side portion, the horizontal portion protruding from the side portion. The polarizer extends to a top surface of the side portion of the guide panel. By doing this, the overall thickness of the display device is reduced to implement a slim design.
