OLED Display Case Slit Spacer Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In OLED display devices, the exposure of the driving circuit to the outside through a slit in the case can lead to malfunction and damage due to external forces, as the structural design creates a vacant space that allows the lower portion of the OLED panel to be pressed, causing the driving circuit to be exposed.
Innovation Solution
A display device design featuring a case with a slit that includes spacers or bent portions at both ends to support the display panel, eliminating the vacant space and preventing the driving circuit from being exposed, thereby maintaining the panel's integrity and functionality under external forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If a slit is formed in the case to expose the driving circuit, then the OLED device becomes slim, but the lower portion of the OLED panel is vulnerable to pressing and the driving circuit may be exposed outside the slit
Solution Approach 1:
A support structure (intermediary element) is introduced between the OLED panel and the case to prevent direct pressing of the panel through the slit. This mediator supports the lower portion of the OLED panel, distributing external forces and preventing the driving circuit from being exposed or damaged while maintaining the slim profile achieved by the slit design
2Reliability
If the case covers the OLED panel and driving circuit completely, then the driving circuit is protected, but the device becomes thicker and loses its slim profile
Solution Approach 1:
The case is segmented with a slit that exposes only the necessary portion for the driving circuit while maintaining overall coverage. The support structure is strategically positioned to provide protection only where needed (at the lower portion through the slit), allowing the rest of the case to remain thin and sleek while still providing adequate protection
3Device complexity
If no support structure is added at the slit, then the device remains simple and slim, but external forces cause pressing of the OLED panel and potential damage
Solution Approach 1:
Instead of adding comprehensive support throughout the entire device, the support structure is localized specifically at the lower portion where the slit exposes the driving circuit. This localized support provides targeted reinforcement against external pressing forces exactly where needed, maintaining device simplicity and slim profile while significantly improving resistance to damage at the vulnerable area

AI summary
A display device is disclosed that can prevent pressing of a substrate and exposure of D-IC to the outside. The display includes a display panel, a driving circuit on one side of a rear surface of the display panel, the driving circuit driving the display panel, and a case receiving the display panel and the driving circuit. The case includes a slit having a predetermined space to expose the driving circuit, and both ends of the slit include a spacer supporting a lower portion of the display panel.
