Liquid Crystal Display Metal Resin Frame Overlap Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid crystal display devices face challenges in further reducing size due to the limitations of the current metal and resin frame structures, which do not effectively overlap to minimize the overall device dimensions.
Innovation Solution
A liquid crystal display device design featuring a metal frame with a first base portion and a first wall portion, and a resin frame with a second base portion and second wall portion, where the liquid crystal display panel is supported on the resin frame's upper surface, allowing the peripheral edge to be positioned above the metal frame's wall portion, thereby reducing the metal frame's size and the device's overall dimensions.

Engineering Contradiction Analysis
1Volume of moving object
If the resin frame is positioned above the cutout of the wall portion of the metal frame, then the device size can be reduced, but further size reduction is limited by the current structural configuration
Solution Approach 1:
The patent transitions from a two-dimensional planar arrangement where the resin frame sits beside the metal frame to a three-dimensional overlapping configuration. The resin frame is positioned to overlap the metal frame in the vertical dimension, with its peripheral edge extending beyond the metal frame's wall portion. This dimensional change allows the device size to be reduced by eliminating the horizontal gap between frames while maintaining structural integrity through vertical layering.
Solution Approach 2:
The resin frame is nested within the boundary defined by the metal frame's wall portion, with its peripheral edge extending beyond the wall portion to provide support. This nesting arrangement allows the smaller resin frame to be positioned within the larger metal frame structure, optimizing space utilization and reducing overall device dimensions while maintaining the cushioning function.
2Volume of moving object
If the metal frame size is reduced by overlapping the liquid crystal display panel, then the device size decreases, but the structural integrity and support function may be compromised
Solution Approach 1:
The resin frame acts as an intermediary element between the metal frame and the liquid crystal display panel. It is positioned to overlap the metal frame's wall portion, with its peripheral edge extending beyond the wall portion to provide direct support to the panel's peripheral edge. This intermediary arrangement allows the metal frame to be smaller while maintaining structural integrity through the resin frame's support function.
Solution Approach 2:
The patent employs a composite frame structure combining metal and resin materials with different properties. The metal frame provides rigidity and protection, while the resin frame provides cushioning and direct panel support. This composite arrangement allows optimization of each material's function, enabling reduced metal frame size while maintaining overall structural integrity through the complementary resin frame.

AI summary
A metal frame includes a first base portion and a first wall portion rising from the first base portion at a position excluding sections of a peripheral edge portion of the first base portion. A resin frame includes a second base portion arranged so as to extend from a region on a central side of the first wall portion of the first base portion to the plurality of sections of the peripheral edge portion, and a second wall portion rising from the second base portion above the plurality of sections. A liquid crystal display panel is supported on an upper surface of the second base portion of the resin frame. A peripheral edge of the liquid crystal display panel is positioned above the first wall portion. The second wall portion of the resin frame is positioned outside the peripheral edge of the liquid crystal display panel.
