Display Apparatus Link Training and Data Validation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display apparatuses connected via interfaces like DISPLAYPORT may experience distorted displays when image data does not meet the set transmission conditions, leading to unsatisfactory display quality and requiring complex user settings to resolve.
Innovation Solution
A display apparatus with a connection control unit that executes link training based on the DISPLAYPORT standard to set transmission conditions, a determination unit that checks if incoming image data satisfies these conditions, and a display control unit that maintains a predetermined display state if the data does not meet these conditions, preventing distorted image display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If automatic connection control is performed to simplify user settings, then ease of operation is improved, but reliability deteriorates when image data does not satisfy transmission conditions
Solution Approach 1:
The determination unit continuously monitors whether image data satisfies the transmission conditions that were automatically set during connection control. When the image data does not meet the conditions, the display control unit receives feedback and changes the display state accordingly, preventing distorted display while maintaining automatic operation.
Solution Approach 2:
The display apparatus automatically performs connection control to set transmission conditions without user intervention. The system then autonomously determines whether incoming image data satisfies these conditions and self-adjusts the display state, eliminating the need for manual user settings while ensuring display quality.
2Manufacturing precision
If transmission conditions are strictly enforced to prevent distorted display, then display quality is improved, but adaptability deteriorates when image data formats vary
Solution Approach 1:
The display apparatus dynamically adjusts its operation based on whether image data satisfies transmission conditions. When conditions are met, normal display operates; when not met, the display state changes to prevent distortion. This dynamic response maintains display quality while adapting to different image data formats and sources.

AI summary
When image data which does not satisfy set conditions is input from a device which outputs image data, a display apparatus prevents a distortion of display. The display device includes a display unit that displays an image based on image data input from the PC, a connection control unit that executes connection control of setting transmission conditions including transmission line capacity of the image data to be output from the PC by transmitting and receiving control information to and from the PC, an input data determination unit that determines whether or not the image data to be input from the PC satisfies the transmission conditions, after the connection control, and a display control unit that sets a display state with the display unit as a predetermined display state, when it is determined that the image data to be input from the PC does not satisfy the transmission conditions.
