OLED Display Frame Structure for Thin, Rigid Heat-Dissipating Assemblies
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge is to reduce the thickness and volume of display devices while enhancing structural rigidity and reducing weight, particularly in display devices using organic light emitting diodes (OLEDs).
Innovation Solution
The display device incorporates a front frame and a rear frame with specific structural configurations, including seating portions, inserts, and clips, which are mechanically bonded or welded, to support the display panel and create a convective heat dissipation space, thereby reducing thickness and weight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a touch screen display device includes a touch sensor, display device, and touch controller, then the device can detect and process touch input, but the connection between components requires separate connection lines that complicate the overall structure and reduce reliability
Solution Approach 1:
The patent combines the display signal transmission function and touch signal transmission function into a single connection interface between the touch controller and display device. The connection lines are integrated such that the same physical connection carries both display data signals and touch sensor signals, eliminating the need for separate dedicated touch signal lines and reducing overall connection complexity.
Solution Approach 2:
The connection interface is designed to serve multiple functions simultaneously: it transmits both display rendering signals from the controller to the display panel and touch sensor signals from the touch sensor to the controller. This multi-functional connection reduces the number of separate connections needed and simplifies the overall system architecture.
2Reliability
If the touch controller is integrated with the display device, then signal transmission distance is reduced and reliability improves, but the manufacturing process becomes more complex
Solution Approach 1:
The touch controller is integrated within the display device structure, with the touch sensor layer positioned above the display panel in a stacked configuration. The controller unit is housed within the same housing as the display device, creating a nested arrangement where the touch functionality is embedded within the display structure without requiring separate external components.
3Ease of manufacture
If the display device has fixed aspect ratio dimensions, then manufacturing is simplified, but the device cannot adapt to different screen size requirements
Solution Approach 1:
The patent makes the aspect ratio of the display panel adjustable rather than fixed. The controller unit is configured to receive adjustment information that changes the aspect ratio parameter, allowing the display to dynamically adapt its display area proportions based on the mounting surface characteristics. This enables the same display device to be used in different applications requiring different aspect ratios.
Solution Approach 2:
The aspect ratio parameter of the display panel is made changeable through software control. The controller unit receives adjustment information that modifies the display area parameters, allowing the effective display dimensions to be adjusted while maintaining the same physical panel. This enables adaptation to different mounting surfaces and application requirements without changing the physical hardware.
