Solution Overview
Problem
Existing display devices face challenges in reducing the bezel area while maintaining the integrity of electronic connections and preventing short circuits or noise interference during bending.
Innovation Solution
The design incorporates a display panel with a circuit layer and display element layer, featuring intersecting bending lines in the non-display area that allows for bending without interfering with electronic connections, using insulation layers and noise shielding elements to prevent interference, and a connection signal line that overlaps the display and non-display areas to maintain functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the bezel area is reduced by making the display panel flexible and bendable, then the display area can be increased relative to the total device area, but the electronic connections and circuitry in the non-display area may be damaged or interfered with during bending
Solution Approach 1:
The non-display area is divided into multiple bent regions with different bending directions. Specifically, a first non-display area is bent along a first bending line, while a second non-display area is bent along a second bending line that intersects the first bending line. This segmentation allows each region to be bent independently in optimal directions, reducing stress on electronic connections while maintaining the reduced bezel area design.
2Area of stationary object
If the non-display area is bent to reduce the bezel area, then the display area ratio is improved, but bending stresses may concentrate and cause short circuits or noise interference
Solution Approach 1:
The patent employs asymmetric bending by introducing intersecting bending lines that create non-uniform bending patterns. The first and second bending lines intersect at different locations and angles, creating asymmetric bent regions that distribute bending stresses more evenly across the non-display area, preventing stress concentration that could lead to short circuits or noise interference.
Solution Approach 2:
The patent introduces a second bending dimension by adding the second bending line that intersects the first bending line. This transforms the bending from a single-dimensional operation to a two-dimensional operation, allowing stresses to be distributed across multiple planes and directions, thereby reducing stress concentration in any single location.
3Adaptability or versatility
If intersecting bending lines are used to reduce bezel area, then the flexibility and bendability are improved, but the complexity of the circuit layer design increases
Solution Approach 1:
The patent applies local quality by configuring the circuit layer with different structures in different regions. The first non-display area and second non-display area have different bending characteristics and circuit arrangements tailored to their specific bending directions. This localized optimization allows each region to handle bending stresses appropriately while maintaining overall system functionality, managing complexity through regional specialization rather than uniform design.
