Grooved Substrate OLED Display Thickness Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional organic light emitting diode (OLED) displays are thick due to the thickness of the OLED and sealant, which increases the overall thickness and may lead to deformation and damage from external factors.
Innovation Solution
The OLED display design includes a first substrate with grooves for the OLED and sealant, and a second substrate with a sealant and getter, where the OLED is partially disposed in the first groove and the sealant is partially in the second groove, forming a strong bond between the substrates to reduce thickness and prevent external damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a sealant is used to couple the first substrate and the second substrate together, then the OLED is protected from external contaminants, but the overall thickness of the display is increased
Solution Approach 1:
The substrate structure is segmented by introducing grooves that divide the substrate into distinct regions. The first groove receives the OLED and the second groove receives the sealant, allowing the sealant to be positioned in a recessed area rather than adding to the overall thickness. This segmentation enables the sealant to perform its protective function while minimizing its contribution to the display's thickness.
2Length of stationary object
If the OLED and sealant thickness are reduced, then the overall display thickness is decreased, but the structural integrity and protection capability may be compromised
Solution Approach 1:
The sealant is nested within the second groove of the substrate, and the OLED is nested within the first groove. This nesting arrangement allows the sealant to be housed within the substrate structure itself, eliminating the need for additional thickness to accommodate the sealant while maintaining its protective function and the overall structural integrity of the display.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration results in a thinner OLED display that is more resistant to deformation and external damage, while maintaining the structural integrity and protecting the OLED from contaminants and moisture.
Implementation Method 1
a sealant at least partially disposed in the second groove... The sealant couples the first substrate and the second substrate together to seal the organic light emitting element

AI summary
An organic light emitting diode display includes a first substrate, an organic light emitting element, a sealant, and a second substrate. The first substrate includes a first groove disposed in a display area of the organic light emitting diode display and a second groove disposed outside the display area. The organic light emitting element is at least partially disposed in the first groove. The sealant is at least partially disposed in the second groove. The second substrate is disposed on the first substrate. The organic light emitting element is sealed between the first substrate and the second substrate via at least the sealant.
