Display Device Panel Driver Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
LCD devices face limitations in minimizing thickness and enhancing aesthetic appearance due to structural constraints, such as increased thickness, step height, and bezel width caused by the external exposure of panel drivers and the need for a separate case to cover them.
Innovation Solution
The LCD device design incorporates a panel driver adhered to the bottom of an extended upper substrate, eliminating the need for a separate case and reducing thickness, with a connection part on the upper substrate electrically connecting the panel driver to a pad on the lower substrate, allowing for a seamless front surface and minimized bezel width.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate case is added to cover the panel driver, then the panel driver is protected from external exposure, but the thickness of the LCD device increases
Solution Approach 1:
The patent merges the case structure with the upper substrate by forming a recess in the upper substrate that directly receives and houses the panel driver. This integration eliminates the need for a separate case component, thereby protecting the panel driver from external exposure while avoiding the thickness increase that would result from adding a separate case on top of the upper substrate.
2Reliability
If a separate case protrudes beyond the upper substrate to cover the panel driver, then the panel driver is protected, but a step height is formed at the front surface, decreasing aesthetic appearance
Solution Approach 1:
The case structure is merged into the upper substrate through the formation of a recess, allowing the panel driver to be housed within the substrate itself rather than protruding beyond it. This integration maintains a flat, seamless front surface appearance while still providing protection for the panel driver.
Solution Approach 2:
The panel driver is nested within a recess formed in the upper substrate, similar to how a doll is placed inside a nested container. This nesting approach allows the driver to be protected while remaining flush with the front surface, eliminating step heights and maintaining aesthetic appearance.
3Reliability
If the case width is increased to prevent panel driver exposure, then the panel driver is protected, but the bezel width increases, decreasing aesthetic appearance
Solution Approach 1:
The protective function previously requiring an extended case is merged into the upper substrate structure. The recess in the upper substrate provides the necessary protection for the panel driver without requiring additional width beyond the substrate edges, thereby preventing bezel width increase while maintaining aesthetic appearance.

AI summary
Disclosed is a display device. The display device includes an upper substrate; a lower substrate having gate and data lines, with exposing a part of the lower surface of the upper substrate; a sealant for adhering the upper substrate to the lower substrate; a panel driver connected to the part of a lower surface of the upper substrate; a pad formed on the lower substrate, for applying a signal to the gate and data lines; and a connection part formed on the upper substrate, for connecting the pad and the panel driver. Accordingly, the thickness of the display device decreases, and a step height is not formed at a front surface of the display device, whereby the present invention can obtain an aesthetic design effect in that the front surface of the display device is shown as one structure.
