Light Chip has been granted a patent for its Micro LED display chip, pixel driving method, and related electronic devices. This patent, titled “Micro-LED Display Chip, Pixel Driving Method for the Chip, and Electronic Devices Using the Same,” was granted by the National Intellectual Property Administration (NIPA) with patent number CN119229796B, and the application was filed in November 2024. The patent highlights Light Chip’s in-depth exploration and innovation in the field of Micro-LED display technology.
Patent Overview
The invention pertains to the field of microdisplay technologies and introduces a Micro-LED display chip, along with a pixel driving method and related electronic devices. The chip’s driving circuit uses digital scanning to drive LED light-emitting elements for display. The digital scanning technique employs PWM (Pulse Width Modulation) signals to control the switching of LED light-emitting elements, achieving grayscale for display images.
A significant feature of this invention is the addition of LED driving current during the high-bit data scanning process, which lowers the pixel clock frequency required during the driving scan. This innovation reduces the performance demands on the surrounding driving circuits of the Micro-LED display chip, enhancing overall system efficiency.
