Bent Non-Display Area Display Module Reducing Bezel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In display devices with multiple modules, the bezel areas between them can lead to poor image visibility due to the large non-display areas, which reduce the overall display surface efficiency.
Innovation Solution
The display module design includes a display panel with a non-display area that is bent, allowing a light blocking member to contact the curved area, reducing the bezel area and increasing the display area by using a supporting member, circuit boards, and a thin film encapsulation layer to manage the display and non-display regions effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a large number of display modules are used to create a large display surface, then the display area increases, but the bezel area between modules increases causing poor image visibility
Solution Approach 1:
The non-display area is bent along a curved surface to reduce the visible bezel area. The bending creates a curved transition from the display area to the rear surface, making the non-display area less prominent and improving image visibility across multiple display modules.
Solution Approach 2:
The non-display area is extended into a third dimension by bending it along a curved surface. This dimensional change allows the non-display area to be positioned in a different spatial plane, reducing its impact on the overall display surface appearance while maintaining electrical connectivity.
2Object-affected harmful factors
If the non-display area is bent to reduce bezel area, then image visibility improves, but the structural complexity increases
Solution Approach 1:
The display panel utilizes a flexible thin film structure that can be bent along a curved surface. This flexible construction allows the non-display area to be curved without requiring complex rigid structural components, achieving bezel reduction while maintaining relatively simple overall device architecture.
3Area of stationary object
If the non-display area is bent and contacted by a light blocking member, then the bezel area is reduced, but the manufacturing precision requirements increase
Solution Approach 1:
The light blocking member is positioned to contact the bent non-display area in advance during the assembly process. This preliminary positioning ensures proper alignment and fixation of the light blocking member on the curved surface, maintaining manufacturing precision while achieving bezel area reduction.

AI summary
A display module including a display panel, a supporting member, a first circuit board, and a light blocking member. The display panel includes a display area and a non-display area. The non-display area is bent. The supporting member includes a first surface overlapping the display area; a second surface opposite to the first surface; and a third surface configured to connect the first surface to the second surface. The first circuit board faces the second surface and is electrically connected to the non-display area. The light blocking member contacts a bent area of the non-display area.
