Display Module Slim Border Design via Extended Polarizer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display modules face challenges in achieving a slim border design due to the need for a larger non-displaying region to accommodate connection circuits, which limits space design flexibility and reduces the display area.
Innovation Solution
A display module design featuring a first polarized plate extending beyond the display panel, with an adhesive tape adhering to the frame, reduces the non-displaying region by protruding the polarized plate's edge, thereby increasing the display area and conforming to slim border requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the non-displaying region is reduced to achieve slim border design, then the displaying region increases, but the connection circuit space becomes insufficient
Solution Approach 1:
The first polarized plate extends beyond the display panel in the lateral direction, utilizing the space dimension outside the traditional display area to provide attachment space for the adhesive tape and connection circuits, thereby resolving the space conflict without reducing the displaying region
Solution Approach 2:
The adhesive tape serves as an intermediary element that connects the extended first polarized plate to the frame, enabling the connection circuit to be routed through the extended region rather than requiring additional space within the display panel boundaries
2Reliability
If the first polarized plate extends beyond the display panel, then the adhesive tape can be properly adhered, but the manufacturing complexity increases
Solution Approach 1:
The first polarized plate is pre-configured to extend beyond the display panel during the manufacturing process, establishing the attachment surface for the adhesive tape before final assembly, which simplifies the overall manufacturing workflow despite the extended geometry
Solution Approach 2:
The extended first polarized plate serves multiple functions: it maintains its optical polarization function over the display area and simultaneously provides an attachment surface for the adhesive tape and connection circuits in the extended region, eliminating the need for separate structural components

AI summary
A display module includes a display panel, a first polarized plate, a second polarized plate, a backlight module, a frame and an adhesive tape. The display panel has a first surface and a second surface opposite to the first surface. The first polarized plate is disposed on the first surface, in which the first end of the first polarized plate extends beyond the display panel. The second polarized plate is disposed on the second surface. The backlight module is disposed under the second polarized plate. The frame surrounds the display panel and carries the backlight module. The adhesive tape is adhered to the first end of the first polarized plate and a side surface of the frame. In addition, an electronic device with the above-mentioned display module is also disclosed.
