Projector Display Controller Activation Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face inconvenience as they cannot determine the status of image supply or projector activation until video images are displayed, leading to insufficient convenience.
Innovation Solution
A display apparatus with a connector for an image outputting device, an activation instructor, a detector, and a display controller that displays different images based on the activation status of the image outputting device, ensuring users are informed of the activation progress.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the projector waits for image supply from the image supplying apparatus before displaying anything, then it ensures proper image transmission setup, but the user cannot grasp the activation status leading to insufficient convenience
Solution Approach 1:
The projector displays a predetermined image (such as a startup screen or loading indicator) before the image supplying apparatus is fully activated. This preliminary visual feedback allows users to understand that the system is initializing, improving convenience without compromising the reliability of the subsequent image transmission setup.
Solution Approach 2:
The projector provides visual feedback to the user during the activation process by displaying a predetermined image. This feedback mechanism informs users about the system's status, reducing uncertainty and improving ease of operation while the image transmission setup is being established in the background.
2Ease of operation
If the projector displays a predetermined image during activation, then user convenience is improved through visual feedback, but additional control functions are required increasing device complexity
Solution Approach 1:
The control section performs multiple functions: it manages the activation of the image supplying apparatus, controls the display of the predetermined image during initialization, and handles the subsequent image transmission. By making the control section multi-functional, the patent improves user convenience without requiring additional dedicated components, thus avoiding increased device complexity.

AI summary
A projector includes a projection section, a first connector to which an image outputting apparatus that outputs first image information is connectable, an activation instructor that instructs activation of the image outputting apparatus, a detector that detects that the activation of the image outputting apparatus has been completed, an image storage that stores second image information, and a display controller that causes the projection section to display a second image corresponding to the second image information when the detector does not detect that the activation of the image outputting apparatus has been completed and causes the projection section to display a first image corresponding to the first image information when the detector detects that the activation of the image outputting apparatus has been completed.
