Display Device Input State Detection and Dynamic Startup Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices project a confirmation image every time they start up when no image information is input, which is cumbersome for users familiar with the operation.
Innovation Solution
A method for controlling a display device that includes input determination to check if image information is input, displaying an input state image indicating whether image information is present or not, and switching to a display image or procedure image based on user interaction with the input state image.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the display device projects a confirmation image every time it starts up when no image information is input, then the user can confirm the connection status, but it becomes cumbersome for users familiar with the operation
Solution Approach 1:
The display device dynamically changes its startup behavior based on the detection result. When external equipment is detected, it projects the confirmation image; when not detected, it projects the home image directly. This dynamic adaptation resolves the contradiction by making the confirmation process conditional rather than fixed.
Solution Approach 2:
The system uses detection feedback from the external equipment to determine the startup display. The detection unit provides feedback about connection status, and the control unit adjusts the display accordingly, creating a feedback loop that optimizes user experience based on actual connection state.
2Loss of information
If the display device displays the confirmation image every time it starts up, then the user can always see the connection status, but it causes user annoyance and reduces operational efficiency
Solution Approach 1:
The display behavior is made dynamic based on detection results. The system adapts its startup sequence - either showing confirmation image or home image - based on whether external equipment is detected, thereby eliminating unnecessary delays while maintaining information visibility when needed.
Solution Approach 2:
The confirmation image display is extracted from the mandatory startup sequence and made conditional. By removing the compulsory nature of the confirmation image display, the system reduces startup time and user annoyance while still providing connection status information when actually connected.
3Ease of operation
If the display device provides detailed procedure images for cable connection, then users can easily connect external equipment, but it increases display complexity and user interaction steps
Solution Approach 1:
The procedure image is prepared in advance as a ready-to-display graphic that provides step-by-step connection guidance. By pre-preparing this visual guide, the system offers detailed connection instructions without requiring complex real-time processing or multiple interaction steps.
Solution Approach 2:
The procedure image acts as an intermediary between the system and the user during cable connection. Instead of requiring direct user-system interaction for connection guidance, the procedure image mediates by providing visual instructions that simplify the connection process while managing display content organization.

AI summary
A method of controlling a display device according to the present disclosure includes the steps of executing input determination on whether or not the image information is input to the input interface, making the display section display an input state image including one of an input image representing that the image information is input and a non-input image representing that the image information is not input in accordance with a result of the input determination, making the display section display a display image based on the image information when receiving an operation of designating the input image, and making the display section display a procedure image representing a procedure of inputting the image information to the input interface when receiving an operation of designating the non-input image.
