Narrow Bezel OSD Switch Segmentation for Crosswise Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices face challenges in arranging OSD switches when the front bezel is narrow, leading to increased thickness or reduced design efficiency, as crosswise arrangements are not feasible and stick-type switches compromise operability.
Innovation Solution
The OSD switches are divided into two sides of the front bezel, allowing for up, down, left, and right disposition, mimicking a crosswise arrangement, with a rotation mechanism and on-screen key guides to enhance operability and visual correspondence.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If OSD switches are arranged in a crosswise direction on the front bezel, then operability is improved, but the front bezel width increases
Solution Approach 1:
The patent divides the OSD switches into two separate groups: a first set of switches arranged in a first direction (e.g., vertically) and a second set of switches arranged in a second direction (e.g., horizontally) on different portions of the front bezel. This segmentation allows crosswise operational capability without requiring a wide single-row arrangement, thus resolving the contradiction between operability and bezel width.
2Area of stationary object
If a stick type operation button is adopted, then space is saved and crosswise operation is enabled, but the thickness direction is increased
Solution Approach 1:
Instead of using a single stick-type button that requires thickness in the Z-direction, the patent segments the controls into multiple flat switches arranged in two directions on the front bezel surface. This maintains crosswise operation capability while keeping the device profile thin by utilizing the X-Y plane rather than adding Z-direction depth.
3Length of stationary object
If the front bezel is narrowed to save space, then design efficiency is improved, but crosswise arrangement of switches becomes impossible
Solution Approach 1:
The patent narrows the front bezel width while maintaining switch arrangement flexibility by segmenting the switches into two directional groups positioned at different locations. The first switches are arranged in a first direction and the second switches in a second direction, enabling crosswise operation within a compact narrow bezel design.
Solution Approach 2:
Instead of arranging all switches in a single row requiring wide bezel space, the patent utilizes two-dimensional arrangement by positioning switches in two different directions (vertical and horizontal) at different portions of the front bezel. This dimensional approach enables crosswise operation capability within a narrow bezel width constraint.

AI summary
A display device in the invention comprises an OSP section and OSD switches 10 configured to include a plurality of switches for performing various kinds of setting operations using the OSD section. In OSD switches 10, switches 10a and 10b are disposed on a right side of a front bezel 2 and switches 10c and 10d are disposed on a lower side of the front bezel 2. By that, the OSD switches can be disposed so that a switch operation can be visually performed without an uncomfortable feeling, without increasing the thickness of a front bezel even if the front bezel is narrow.
