Display Device Panel Driver Integration and Light Reflection Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices face limitations in minimizing thickness and enhancing aesthetic appearance due to structural properties, which result in increased thickness and a deteriorated appearance caused by the need for a case to cover the panel driver, leading to a height difference and wider bezel.
Innovation Solution
The display device incorporates a design where the panel driver is connected to the lower surface of the upper substrate, eliminating the need for an additional case, and features reflection-preventing layers on the upper substrate to minimize light reflection and improve picture quality, while a support member with a set cover contacts the lateral or lower surface of the upper substrate to maintain a flat front surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a case is formed above the upper substrate to cover the panel driver, then the panel driver is prevented from being exposed to the external, but the thickness of the display device is increased
Solution Approach 1:
The case and upper substrate are merged into a single integrated structure where the case is formed as an extension of the upper substrate. This eliminates the need for a separate case component and reduces the overall thickness while maintaining protection of the panel driver.
Solution Approach 2:
The panel driver is relocated from the traditional position below the lower substrate to the peripheral region of the upper substrate. This dimensional repositioning allows the driver to be covered by the case formed on the upper substrate, eliminating the need for increased thickness to protect the driver.
2Reliability
If a case is formed above the upper substrate to cover the panel driver, then the panel driver is prevented from being exposed to the external, but the aesthetic appearance is deteriorated due to height difference
Solution Approach 1:
The case and upper substrate are merged into a single integrated structure with a flush front surface. This eliminates the height difference and step between the case and upper substrate, creating a smooth, aesthetically pleasing appearance while still protecting the panel driver.
3Reliability
If the case is increased in width to prevent exposure of panel driver, then the panel driver is covered, but the bezel width is increased, deteriorating aesthetic appearance
Solution Approach 1:
The panel driver is repositioned to the peripheral region of the upper substrate, utilizing the existing boundary area. This allows the driver to be covered by the case without requiring an increase in case width or bezel width, maintaining a compact and aesthetically pleasing design.
