Display Apparatus Adjustable Spacing Mechanism Narrow Bezel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display apparatuses with narrow bezel structures face challenges in maintaining optimal display quality due to the pressure exerted on optical sheets, which can impair image display.
Innovation Solution
A display apparatus design featuring a bottom receiving member with protrusions and an intermediate frame with distance adjusting grooves allows for adjustable spacing between the cover portion and the backlight unit, preventing the optical sheet from being pressed against the cover and enhancing display quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a narrow bezel structure is adopted to minimize the width of the non-active area, then the display apparatus achieves a more compact and modern appearance, but the optical sheet is pressed against the cover portion which impairs image display quality
Solution Approach 1:
A distance adjusting portion (groove) is introduced as an intermediary element between the cover portion and the optical sheet. This groove receives a protrusion from the bottom receiving member, creating a mechanical intermediary that controls and maintains the spacing between the cover portion and the optical sheet, preventing direct contact and pressure on the optical sheet while enabling narrow bezel design
2Volume of moving object
If the cover portion is positioned close to the backlight unit to achieve narrow bezel, then the overall device size is reduced, but the optical sheet cannot maintain optimal spacing which degrades display quality
Solution Approach 1:
The distance adjusting portion (groove) and protrusion form a self-adjusting mechanical interface that automatically maintains the correct spacing between components. During assembly, the protrusion fits into the groove, and the geometry of this interface self-regulates the distance between the cover portion and the optical sheet, ensuring precise spacing without requiring complex external adjustment mechanisms
Solution Approach 2:
The invention changes the geometric parameters of the distance adjusting portion (groove dimensions, depth, and shape) and the corresponding protrusion to precisely control the spacing between components. By optimizing these geometric parameters, the design achieves both compact size and precise spacing control, resolving the contradiction between miniaturization and manufacturing precision
3Device complexity
If fixed spacing structure is used between cover portion and backlight unit, then assembly is simplified, but adjustment of optical sheet position is impossible which reduces adaptability
Solution Approach 1:
The distance adjusting portion transforms the static fixed spacing structure into a dynamic adjustable structure. The groove-protrusion interface allows for controlled movement and positioning adjustments while maintaining stability during operation. This dynamic feature enables adaptability in spacing adjustment without significantly increasing overall device complexity, as the adjustment mechanism is integrated into the existing structural components

AI summary
A display apparatus includes a backlight unit generating light, a bottom receiving member including a bottom portion and a first sidewall portion extending from the bottom portion to define a receiving space accommodating the backlight unit, an intermediate frame coupled to the bottom receiving member including a second sidewall portion facing the first sidewall portion and a cover portion extending inward from the second sidewall portion to cover an upper edge of the backlight unit, and a display panel on the cover portion for receiving the light from the backlight unit and displaying an image. The bottom receiving member includes a protrusion protruding outward from the first sidewall portion, and the intermediate frame includes a distance adjusting portion in an inner side surface of the second sidewall portion engaged with an outer surface of the protrusion to move the cover portion along a z-axis direction away from the bottom portion.
