Touch Display Panel OSD Menu Trigger via Multiplexer Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display devices with physical keys for on-screen display (OSD) menu functions become complex and inconvenient as the number of keys increases, occupying hardware space and complicating operations.
Innovation Solution
A display device that triggers the OSD menu function using a touch display panel, reducing the need for physical keys by detecting touch inputs to set parameters, with a multiplexer and touch screen controller facilitating the transition between normal and screen adjustment modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If physical keys are used to control OSD menu, then parameter adjustment function is achieved, but device complexity and hardware space increase
Solution Approach 1:
The patent replaces the mechanical physical key system with a touch-based control system. The touch display panel detects touch coordinates and patterns to trigger OSD menu functions, eliminating the need for physical keys while maintaining parameter adjustment capability. This substitution reduces hardware complexity and space requirements.
Solution Approach 2:
The touch display panel serves multiple functions: it displays images normally and also serves as the control interface for OSD menu when touch patterns are detected. This multi-functionality eliminates the need for separate physical keys, as the same hardware component performs both display and control roles.
2Adaptability or versatility
If multiple physical keys are added to increase functions, then more parameters can be adjusted, but operation complexity increases
Solution Approach 1:
The patent transitions from one-dimensional physical key presses to two-dimensional touch coordinate detection on the display panel. By detecting the position, duration, and pattern of touch inputs, the system can differentiate between multiple commands using a single interface, thereby increasing versatility without increasing operational complexity.
Solution Approach 2:
The system creates virtual representations of control functions on the touch display panel. Instead of physical keys, touch-sensitive zones replicate the functionality of physical keys through software control, allowing multiple parameters to be adjusted through touch patterns rather than multiple physical components.
3Ease of operation
If physical keys are configured, then OSD menu control is achieved, but hardware space is occupied
Solution Approach 1:
The patent merges the display function and control function into a single integrated interface. The touch display panel combines the visual output function with the input control function, eliminating the need for separate physical key hardware. This merging reduces the overall hardware footprint while maintaining full OSD menu control capability.

AI summary
A display device having an on-screen display (OSD) menu function is provided, which includes a touch display panel, a touch screen controller, a display circuit, and a multiplexer. The touch display panel includes a display layer and a touch layer. The touch screen controller detects the touch layer and outputs a first detection result. The display circuit displays a first image of a first image source on the display layer, and the display circuit has the OSD menu function. In a normal display mode, the multiplexer transmits the first detection result of the touch screen controller to the first image source. If the first detection result complies with a predetermined pattern, the OSD menu function of the display circuit is triggered, and the display circuit enters a screen adjustment mode, and the multiplexer transmits the first detection result of the touch screen controller to the display circuit.
