Bendable Light-Transmissive Layer for Narrow Bezel Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional non-self-luminous display devices require a thick sealant to ensure structural stability, leading to a thicker bezel due to increased contact area, which complicates the achievement of a narrow-bezel design and increases costs.
Innovation Solution
A display device incorporating a bendable light-transmissive layer that covers the display panel and backlight module from above and side, eliminating the need for a thick sealant and allowing for a direct connection without additional adhesive layers, thereby reducing bezel thickness and simplifying the manufacturing process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a thick sealant is used to ensure structural stability, then the reliability is improved, but the bezel thickness increases
Solution Approach 1:
The patent extracts the sealing function from the traditional thick sealant and relocates it to the peripheral edges of the display panel and backlight module. This is achieved by providing sealing layers at the edges that extend laterally, allowing the main body of the device to have reduced thickness while maintaining sealing integrity through the peripheral sealing structure.
Solution Approach 2:
The patent transitions from a vertical sealing approach (thick sealant in the thickness direction) to a lateral sealing approach (sealing layers extending in the lateral direction). By changing the dimension of sealing from vertical to horizontal, the patent achieves reliable sealing while reducing the overall bezel thickness of the display device.
2Reliability
If a thick sealant is used to ensure structural stability, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The patent merges the sealing function with the edge structure of the display panel and backlight module. Instead of using a separate thick sealant layer, the sealing layers are integrated into the peripheral edges, combining structural support and sealing functions into a single integrated structure that simplifies manufacturing.
Solution Approach 2:
The patent employs thin sealing layers at the peripheral edges instead of thick rigid sealant. These thin sealing films provide sufficient sealing capability while being easier to apply and integrate into the manufacturing process, reducing overall device complexity.

AI summary
Disclosed is a display device comprising a display panel, a backlight module and a bendable light-transmissive layer. The display panel comprises a light incident surface and a light exit surface opposite to each other and a plurality of panel sides connecting the light incident surface with the light exit surface. The backlight module is located on the light incident surface of the display panel and comprises a first surface facing the light incident surface, a second surface opposite to the first surface, and a plurality of module sides connecting the first surface with the second surface. The bendable light-transmissive layer at least partially covers the light exit surface of the display panel, the plurality of panel sides and the plurality of module sides to fix the display panel and the backlight module.
