Solution Overview
Problem
Conventional display apparatus user interfaces face challenges in providing intuitive and convenient function selection due to spatial limitations and reliability issues, especially with thin designs and metal bezels, which hinder button press accuracy and visibility.
Innovation Solution
A display apparatus incorporating a signal receiver, image processor, display unit, function selector with proximity and touch sensors, and a controller that displays an on-screen display (OSD) menu for function selection, allowing users to choose functions via proximity and touch operations, and operates selected functions accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a control panel with buttons is placed on the front side of the display apparatus, then function selection is directly accessible, but the edge design becomes narrow and spatial space is reduced
Solution Approach 1:
The patent transitions the control interface from a physical 2D button panel on the device edge to a 2D graphical user interface on the display screen itself. This dimensional shift allows function selection without consuming physical edge space, resolving the contradiction between accessibility and narrow edge design.
Solution Approach 2:
The patent creates a virtual copy of the control interface by displaying function selection options as graphical elements on the screen rather than using physical buttons. This virtual representation allows users to interact with controls without requiring physical space on the device edges.
2Area of stationary object
If a control panel is placed on the lateral side of the display apparatus, then spatial space is maintained, but the user cannot readily view the control panel
Solution Approach 1:
The patent makes the display screen serve multiple functions: both displaying content and providing the control interface. This multi-functionality eliminates the need for separate control panels on lateral sides, maintaining space while ensuring control visibility through the primary display area.
Solution Approach 2:
By moving controls to the display screen dimension, the patent ensures visibility from the user's viewing position while maintaining the spatial advantages of thin or lateral designs. The control interface becomes visible in the same plane as the display content.
3Area of stationary object
If a touch type control panel using electrostatic sensor is applied to a metal bezel, then spatial limitation is overcome, but reliability deteriorates due to noise
Solution Approach 1:
The patent introduces the display screen as an intermediary layer between the user's touch input and the control function execution. Instead of direct electrostatic sensing on the metal bezel, users interact with graphical elements on the screen, eliminating the noise interference issue while maintaining spatial flexibility.
Solution Approach 2:
The patent replaces the electrostatic sensing mechanism with a visual interaction system. Control functions are activated through graphical user interface elements displayed on the screen, substituting the unreliable electrostatic sensor approach with a more reliable visual-tactile interaction method.
4Ease of operation
If the control panel buttons are made large for ease of pressing, then usability is improved, but the thin design requirement is compromised
Solution Approach 1:
The patent creates a virtual copy of the control interface on the display screen, allowing large, easily pressable control elements without requiring physical thickness. The graphical representations of controls can be made as large as needed for ease of operation while the actual device remains thin.
Solution Approach 2:
The patent uses the display screen's graphical output as a temporary, virtual representation of controls that disappears or changes when not in use. This allows large control elements to appear only when needed, maintaining thin device design while providing ease of operation during interaction.
