Display Device Touch Input Cursor Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In digital TV services, the distinction between touch inputs and mouse inputs is not effectively managed during screen mirroring, leading to unnecessary display of a mouse cursor when a touch input is received, causing confusion and resource inefficiency.
Innovation Solution
A display device with a wireless communication unit that receives a first video signal from a terminal and transmits a packet without a mouse cursor parameter when a touch input is detected, preventing the display of a mouse cursor and allowing natural control operations based on touch inputs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the TV displays a mouse cursor when receiving touch input during screen mirroring, then the terminal can control the TV interface, but the touch input and mouse input are not distinguished and unnecessary cursor display occurs
Solution Approach 1:
The patent extracts the mouse cursor parameter from the UIBC packet transmission when touch input is detected. The control unit determines the input type and selectively includes or excludes the mouse cursor parameter based on whether the input is from a touch interface or mouse device, thereby preventing unnecessary cursor display while maintaining functional control capability.
2Reliability
If the TV transmits and displays mouse cursor coordinates for every input, then cursor control functionality is maintained, but data resources are wasted and user experience is complicated
Solution Approach 1:
The patent implements dynamic adjustment of data transmission based on input type. The control unit dynamically determines whether to include the mouse cursor parameter in UIBC packets based on real-time detection of input source (touch interface versus mouse), thereby optimizing data resource consumption while maintaining reliable control functionality when needed.
Solution Approach 2:
The patent changes the parameter composition of UIBC packets based on input type. When touch input is detected, the mouse cursor parameter is excluded from the packet; when mouse input is detected, the parameter is included. This parameter adjustment optimizes data transmission efficiency and reduces unnecessary resource consumption.
3Adaptability or versatility
If the TV supports both touch UIBC and mouse cursor functions, then versatile input methods are provided, but the distinction between input types becomes ambiguous
Solution Approach 1:
The patent segments the control functionality based on input type. By detecting whether the input originates from a touch interface or a mouse device, the system applies different processing paths: touch inputs trigger UI control without cursor display, while mouse inputs trigger cursor display. This segmentation maintains versatility while eliminating ambiguity in input differentiation.

AI summary
According to an embodiment of the present disclosure, a display device may include a wireless communication unit configured to wirelessly receive a first video signal based on a first video being displayed by a terminal, a display unit configured to display a first mirroring video based on the first video signal, and a control unit configured to receive a user input while the first mirroring video is being displayed, and transmit, to the terminal, a packet that does not include a mouse cursor parameter for requesting coordinates of a mouse cursor when the received user input is a touch input.
