Display Device Polarizer Integration for Thinner Bezel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices face challenges in further reducing panel structure thickness and optimizing the display module structure for better viewing experiences, as the narrowing and thinning of frames have reached process limits.
Innovation Solution
The design includes a back frame with a cavity housing a display module and a polarizer extending into the non-display area, replacing the traditional front frame, with a light-shielding layer and high-viscosity layer for protection and seamless integration, increasing the screen-to-body ratio and reducing thickness.

Engineering Contradiction Analysis
1Area of stationary object
If the frame of the display module is narrowed and thinned, then the screen-to-body ratio is improved, but the manufacturing process reaches its limit and cannot be optimized further
Solution Approach 1:
The patent merges the front frame and back frame into a single integrated frame structure. The frame includes a front frame portion and a back frame portion that are formed as one piece, eliminating the need for separate assembly of front and back frames. This integration allows for further reduction of frame width and thickness while maintaining structural integrity and simplifying the manufacturing process.
Solution Approach 2:
The integrated frame structure serves multiple functions: it provides structural support, houses the display module, and maintains the narrow bezel design. The frame's unified structure allows it to perform both the protective function of a traditional front frame and the structural function of a back frame simultaneously.

If the back frame and front frame are narrowed and thinned, then the display module structure is optimized, but the manufacturing process cannot achieve further reduction
Solution Approach 1:
The patent combines the front frame and back frame into a single integrated frame structure. This unified design eliminates the need for separate manufacturing and assembly of front and back frames, allowing for further thickness reduction while maintaining structural strength. The integrated frame can be manufactured as a single component, overcoming the limitations of traditional multi-part construction.
3Area of stationary object
If the display module structure is optimized for narrower frames, then the viewing experience is improved, but the existing manufacturing process cannot achieve further optimization
Solution Approach 1:
The integrated frame structure simplifies the overall device complexity by eliminating the need for separate front and back frame assemblies. This unified structure makes it easier to optimize the display module layout and maximize the display area, as there are fewer structural components to accommodate and align during manufacturing.

AI summary
A display device is provided. The display device includes a back frame, a display module, and a polarizer. The back frame has a cavity, and the display module is disposed in the cavity. The polarizer is arranged on the display module and a body of the back frame surrounding the display module. The polarizer is extended to the back frame in the non-display area, thereby removing a front frame in the prior art, reducing a thickness of the display device, and increasing an area of the display area.
