Latest Patents

One of his latest patents is for an electronic device and associated signal processing method. This invention includes a decoder circuit, an image processing circuit, a detection circuit, a transmission interval determination circuit, an auxiliary data extraction circuit, and an encoder circuit. The decoder circuit decodes an input signal to generate a decoded signal, while the image processing circuit performs image processing on this signal to produce processed image data. The detection circuit identifies the timing of an active display area and a vertical synchronization signal in the processed image data, generating a detection result. The transmission interval determination circuit then establishes a transmission interval for the processed image data based on this result. Additionally, the auxiliary data extraction circuit extracts auxiliary data from the decoded signal, and the encoder circuit integrates this data into the transmission interval of the processed image data, performing encoding to generate an output signal.

Another significant patent is for a backlight control device designed to manage multiple backlight sources. This device features timing control circuitry and local-dimming control circuitry. The timing control circuitry generates a transmission packet according to a first customized content specification, which includes control information and brightness information. It incorporates a differential circuit that transmits the packet based on a differential voltage level. The local-dimming control circuitry includes a receiving circuit that is electrically coupled to the differential circuit, allowing it to receive the transmission packet. This circuitry is responsible for transmitting a light source control signal based on the control and brightness information.
