Display Apparatus Thru-Hole Coupling for Thin Profile
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display apparatuses are hindered by increased thickness due to the placement of printed circuit boards under the display panel, which also leads to potential separation issues during assembly, resulting in bulkier and less efficient designs.
Innovation Solution
The display apparatus features a top chassis with thru-holes that securely couple with the printed circuit board using a coupling member, allowing the board to be positioned alongside the display panel without overlapping it, thereby reducing overall thickness and preventing separation, while a light guide plate and light source enhance image display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the printed circuit board is disposed under the display panel, then the electrical connection is achieved, but the thickness of the display apparatus increases
Solution Approach 1:
The patent transitions from a vertical stacking arrangement (PCB under display panel) to a horizontal side-by-side arrangement. The PCB is repositioned to the side of the display panel, and through-holes are created in the chassis to allow coupling members to pass through and secure the PCB laterally, eliminating the need for vertical thickness accommodation.
Solution Approach 2:
The PCB is extracted from its conventional position underneath the display panel and repositioned to a lateral location. This extraction removes the conflict between the PCB and display panel in the vertical dimension, allowing both components to coexist without increasing overall thickness.
2Ease of manufacture
If the printed circuit board is separated from the display panel during assembly, then the assembly process is simplified, but the coupling stability is reduced
Solution Approach 1:
The chassis is pre-formed with through-holes positioned to align with mounting features on the PCB during assembly. This preliminary preparation of the chassis structure enables straightforward insertion and securing of the PCB through the through-holes, simplifying the assembly process while ensuring stable coupling.
Solution Approach 2:
The coupling function is merged into the chassis structure itself through the integration of through-holes. The chassis not only provides structural support but also incorporates the coupling mechanism, combining multiple functions into a single component and simplifying the overall assembly.
3Length of stationary object
If the overall thickness is reduced by repositioning the printed circuit board, then the display apparatus becomes thinner, but the structural complexity increases
Solution Approach 1:
The chassis is segmented into regions with different thicknesses to accommodate the through-holes and coupling mechanisms. The side portion of the chassis includes a first region with a first thru-hole and a second region with a second thru-hole, creating localized structural variations that enable PCB coupling without affecting the overall thin profile.
Solution Approach 2:
The coupling members are nested within the through-holes of the chassis, with the PCB positioned laterally against the display panel. This nesting arrangement secures the PCB within the chassis structure while maintaining a compact, thin overall configuration.

Function Achieved in This Case
This configuration minimizes the overall thickness of the display apparatus and ensures secure coupling of components, achieving a lightweight, thin-shaped, and low-power consumption design with improved assembly stability and image quality.
Implementation Method 1
a light guide plate under the display panel. The light guide plate guides the light emitted from the light source to the display panel
Implementation Method 2
The first thru-hole includes a first screw mountain and a first screw valley on an inner wall of the first thru-hole, and the coupling member includes a second screw valley and a second screw mountain, which are coupled with the first screw mountain and the first screw valley, respectively

AI summary
A display apparatus includes a display panel which receives a light and displays an image, a bottom chassis which accommodates the display panel, and a top chassis which faces the bottom chassis with the display panel therebetween. The top chassis overlaps a portion of the display panel and includes a first thru-hole which extends through a thickness of a side portion thereof. The display apparatus includes a printed circuit board and a coupling member. The printed circuit board applies an electrical signal to the display panel, is under the side portion, and includes a second thru-hole which corresponds to the first thru-hole. The coupling member extends through the first thru-hole and the second thru-hole, and couples the top chassis and the printed circuit board to each other.
