Touch Region Display Panel for OSD Menu Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display technologies with physical OSD menu keys are cumbersome and complex, especially with increasing resolution and refresh rates, leading to reduced user experience due to the need for frequent key switching and increased adjustment time.
Innovation Solution
A display panel with a touch region that includes touch buttons and keys, allowing for touch operation to replace physical keys, featuring a timer control register, microcontroller, power management integrated circuit, and touch integrated circuit to manage touch signals and parasitic capacitance, enabling efficient parameter adjustment and improving user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If physical OSD menu keys are provided on the display frame, then users can adjust display parameters, but the operation becomes cumbersome and complex with increasing display functions
Solution Approach 1:
The patent replaces physical mechanical keys with a touch-sensitive display interface. The display panel includes a touch-sensitive layer that detects user touches directly on the screen to adjust OSD menu parameters, eliminating the need for separate physical buttons on the display frame. This substitution reduces mechanical complexity while improving ease of operation.
Solution Approach 2:
The display screen serves multiple functions: it displays visual content and simultaneously functions as the control interface for OSD menu operations. By integrating the control functionality into the display itself, the system reduces the number of separate components needed, simplifying the overall device structure while maintaining comprehensive control capabilities.
2Adaptability or versatility
If more physical keys are added to achieve complex functions, then more functions can be controlled, but the complexity and adjustment time of function selection increases
Solution Approach 1:
The patent transitions from a one-dimensional control approach (physical buttons arranged linearly on the frame) to a two-dimensional touch interface on the display screen. This allows multiple functions to be accessed simultaneously through on-screen menu options, reducing the sequential time required to access and adjust different display parameters.
Solution Approach 2:
The patent creates a virtual representation of the OSD menu controls directly on the display screen, allowing users to interact with graphical buttons and sliders that mirror traditional physical controls. This virtual interface consolidates multiple function controls into a single accessible location, reducing the time needed to adjust various display settings compared to searching for and switching between multiple physical keys.
3Ease of operation
If a full-screen touch display is implemented, then user interaction is simplified, but the cost increases significantly
Solution Approach 1:
The patent implements touch functionality only in specific localized regions of the display panel where OSD menu controls are needed, rather than making the entire screen touch-sensitive. This selective approach maintains simplified user interaction in critical control areas while significantly reducing manufacturing costs compared to a full-screen touch display implementation.
