OLED Display Frame Covering Border Gaps Without Exterior Case
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional OLED display devices require additional exterior cases to improve appearance, which increases weight, reduces portability, and increases fabrication costs and time due to assembly complexities and border gaps between components.
Innovation Solution
An OLED display device with a dual-structured main frame comprising a body frame and a cap frame that modularizes the OLED panel, bottom frame, and window, eliminating the need for an additional exterior case by covering border gaps and enhancing assembly efficiency through a fitting and sliding mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If an additional exterior case is used to cover the border gap and improve appearance, then the appearance quality is improved, but the weight and thickness of the device increase
Solution Approach 1:
The patent merges the border gap covering function into the main frame structure itself. The main frame includes a first frame body and a second frame body that are coupled together to form a unified structure that inherently covers the border gap between the OLED panel and the main frame, eliminating the need for a separate exterior case.
Solution Approach 2:
The main frame is designed to serve multiple functions simultaneously: it provides structural support, covers the border gap for aesthetic purposes, and maintains the thin profile of the device. The dual-frame body structure achieves both structural integrity and appearance quality without requiring additional components.
2Shape
If an additional exterior case is used to cover the border gap, then the appearance quality is improved, but the fabrication cost and fabrication time increase
Solution Approach 1:
The patent combines the border gap covering function into the main frame structure itself. The main frame includes a first frame body and a second frame body that are coupled together to form a unified structure that inherently covers the border gap between the OLED panel and the main frame, eliminating the need for a separate exterior case.
Solution Approach 2:
The main frame is divided into a first frame body and a second frame body that can be manufactured separately and then coupled together. This segmentation allows for easier manufacturing and assembly while still achieving the unified appearance quality without additional exterior cases.
3Reliability
If a gap space is required among the OLED panel, main frame and bottom frame to prevent crack during thermal impact test, then the reliability is improved, but a border gap is generated that deteriorates appearance
Solution Approach 1:
The patent merges the border gap covering function into the main frame structure itself. The main frame includes a first frame body and a second frame body that are coupled together to form a unified structure that inherently covers the border gap between the OLED panel and the main frame, eliminating the need for a separate exterior case.

Function Achieved in This Case
The solution results in a lightweight, thin-profile OLED display device with improved appearance and reduced fabrication costs and time, while maintaining reliability and durability without the need for additional exterior casing.
Implementation Method 1
The organic emitting layer emits a light due to transition of an exciton generated by combination of the hole and the electron in the organic emitting layer from an excited state to a ground state

AI summary
An organic light emitting display assembly (200) includes a body frame (210) and a cap frame (220) that are assembled to secure an organic light emitting diode display panel (110) between the assembled body frame (210) and cap frame (220). A tolerance gap (G) is present between the perimeter edge of the organic light emitting diode display panel (110) and the body frame (210) to allow for convenient placement of the OLED display panel (110) in the frame. The cap frame (220), attached over the body frame (210) via an insertion groove (215), includes a cap horizontal portion (221) that covers the top surface of a body vertical portion (211) of the body frame (210). One side surface (221b) of the cap horizontal portion (221) of the cap frame (220) covers the gap (G) between the organic light emitting diode display panel (110) and the body frame (210).
