FUNCTIONAL SAFETY DISPLAY CONTROLLER - A simplified explanation of the abstract
This abstract first appeared for US patent application 18302272 titled 'FUNCTIONAL SAFETY DISPLAY CONTROLLER
Simplified Explanation
The patent application describes a method for controlling a functional safety display controller by rendering test data in a defined test area of a display device during synchronization phases of the raster scan, generating a checksum of the rendered test data, and comparing it with a previously generated checksum to verify the functionality of the display controller.
- Visible display area defined in display controller
- Test area rendered with test data during synchronization phases
- Checksum generated and compared to verify functionality
Potential Applications
The technology described in the patent application could be applied in various industries where functional safety display controllers are used, such as automotive, aerospace, industrial automation, and medical devices.
Problems Solved
This technology helps ensure the proper functionality of display controllers in critical systems by providing a method to verify their performance during operation.

Potential Commercial Applications
Safety-critical industries such as automotive, aerospace, and medical devices could benefit from implementing this technology in their display controllers to enhance the safety and reliability of their systems.
Possible Prior Art
One possible prior art could be the use of checksums in data transmission protocols to verify data integrity, but the specific application of generating and comparing checksums in a display controller during synchronization phases of a raster scan may be novel.
What is the impact of this technology on display controller performance?
The technology described in the patent application aims to improve the functionality and reliability of display controllers in safety-critical applications by providing a method to verify their performance during operation. By rendering test data in a defined test area and generating checksums during synchronization phases, the display controller's functionality can be verified, leading to increased system safety and performance.
How does this technology contribute to overall system safety?
This technology contributes to overall system safety by ensuring the proper functionality of display controllers in critical systems. By verifying the performance of the display controller through the generation and comparison of checksums, potential errors or malfunctions can be detected and addressed, leading to a safer operational environment for the system as a whole.
Original Abstract Submitted
A method for controlling a functional safety display controller including defining in a display controller, a visible display area of a display device, wherein the display device is configured to raster scan a series of pixel intensity data, the raster scan including at least one synchronization phase. A test area of the display device is defined to be mutually exclusive of the visible display area. A test data is rendered in the test area to generate a rendered test data during the at least one synchronization phase of the raster scan. A checksum of the rendered test data is generated. The checksum is compared with a previously generated checksum to verify a functionality of the display controller.
