Fuman Micro obtains patents for image data output circuit, display circuit and method
div class content id article News on April 8, 2024, according to the announcement of the State Intellectual Property Office, Fumman Microelectronics Group Co., Ltd. has obtained a project called Image Data Output Circuit, Display Circuit and Method, with authorization announcement number CN110599951B, and the application date is October 2019. div class dpu8C 2kCxD p The patent summary shows that in the image data output circuit provided by the present invention, the output end of the grayscale counter is connected to an input end of the first comparator, the high M bits of the external input data are input to the other input end of the first comparator, the output end of the first comparator is connected to an input end of the OR gate; the output end of the subframe counter is connected to an input end of the second comparator, the low N bits of the external input data are input to the other input end of the second comparator, and the output end of the second comparator is connected to the other input end of the OR gate; the external input data is M N bit; the output terminal of the grayscale counter is connected to the clock terminal of the row counter, and the output terminal of the row counter is connected to the clock terminal of the subframe counter; the output terminal of the OR gate is connected to the column driver terminal of the LED screen. This circuit does not need to increase the display counting clock frequency, which is fully guaranteed It improves the characteristics of the original LED screen device, solves the flickering phenomenon, completely displays image data exceeding 10 bits, and improves the LED screen display effect. p div div class dpu8C 2kCxD p br p div div
