Hikvision applies for patent for phase anomaly detection method of LED display

News on March 4, according to an announcement from the State Intellectual Property Office, Hangzhou Hikvision Digital Technology Co., Ltd. applied for a project called "Phase anomaly detection methods, equipment and computer program products for LED displays", with the public number CN117636768A, and the application date is December 2023.

The patent abstract shows that this embodiment provides a phase anomaly detection method, equipment and computer program product for an LED display screen. This embodiment sets a hardware connection method on the LED display screen. Specifically, the hardware connection method can be: the FPGA is connected to the first driver IC among the N driver ICs through the middleware, and the last driver IC among the N driver ICs is connected to the FPGA through the middleware. After that, by setting the above hardware connection method, the original mechanism of the last driver IC not outputting is improved. In this embodiment, the last driver IC returns the processed data signal to the FPGA, which enables the FPGA to use the data signal sent through this hardware connection method. signal and clock signals, as well as the data signals and clock signals received through this hardware connection method to automatically implement phase anomaly detection on the LED display.
