Directional Manipulation Panel for Direct Channel Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display apparatuses face challenges in providing an efficient channel selection mechanism due to limited space, especially in modern designs with narrower bezels, where users must sequentially navigate through channels using minimal buttons, making it inconvenient to select non-adjacent channels.
Innovation Solution
Incorporating a manipulation panel with a plurality of direction keys (top, bottom, left, and right) on the lateral or side of the display apparatus, allowing users to input commands to move within a number keypad interface, enabling direct selection of channel numbers and improving user interface functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the manipulation panel is provided with minimal buttons arranged in a row, then the device complexity is reduced and the design is simpler, but the ease of operation deteriorates because users must sequentially navigate through channels making it inconvenient to select non-adjacent channels
Solution Approach 1:
The patent transforms the one-dimensional linear arrangement of buttons into a two-dimensional directional key layout (up, down, left, right). This dimensional change allows users to navigate channel numbers more efficiently by directly inputting desired channels rather than sequentially navigating, thus improving ease of operation while maintaining simple device complexity
Solution Approach 2:
The directional keys are designed to serve multiple functions: they can be used for channel selection, volume control, and other navigation tasks within the user interface. This multi-functionality allows the manipulation panel to provide enhanced operational capabilities without adding dedicated buttons for each function, thereby maintaining device complexity at an acceptable level
2Ease of operation
If the manipulation panel is provided in the front or lateral side of the display apparatus, then the ease of operation is improved, but the device complexity increases and the aesthetic design is compromised due to narrower bezels
Solution Approach 1:
The manipulation panel is strategically positioned in specific locations (front side, lateral side, upper side, or lower side) of the display apparatus where it can be easily accessed by users. This localized placement optimizes operational convenience while adapting to the narrow bezel design constraints, avoiding the need for complex integration throughout the entire device structure
3Device complexity
If the manipulation panel has only two channel-change buttons arranged side by side, then the device complexity is minimized, but the productivity deteriorates because users must repeatedly manipulate buttons to change to non-adjacent channels
Solution Approach 1:
By arranging keys in a directional pattern (up, down, left, right) rather than a linear sequence, the patent enables users to more efficiently navigate and select channel numbers. This dimensional reorganization allows for faster channel selection without increasing the total number of keys, thus improving productivity while maintaining minimal device complexity

AI summary
A display apparatus and a control method which receives a user's input by using a manipulation panel are provided. The display apparatus includes: an image processor; a display unit; a user input unit which includes a manipulation panel; and a controller which controls the display unit to display a user interface (UI) including a number keypad upon receiving a preset user's input from the user input unit and receives a user's selection to select a channel number from the number keypad according to a user's input to the direction key. Thus, the direction keys are provided in the manipulation panel installed in a front or lateral side of the display apparatus and a user may input a desired channel number without difficulty when selecting channels through the manipulation panel.
