Display updating system using usb interface for program codes
The granted patent US12046216B2 outlines a system designed for managing display program codes through a USB interface. The system comprises a display that includes a display panel, a USB hub for receiving multiple display program codes, and a display control circuit that connects the display panel and USB hub. This control circuit is responsible for receiving and storing the display program codes. Additionally, an electronic device is linked to the display via the USB interface, featuring a memory for storing these codes, a USB driver circuit, and a calculation circuit that manages the transmission of the display program codes through the USB interface.
Further claims detail the integration of multiple displays within the system, allowing for a second display that operates similarly to the first. This second display includes its own panel, USB hub, and control circuit, which are interconnected with the first display's components. The claims also specify the use of an Inter-Integrated Circuit (I2C) bus interface for communication between the USB hub and display control circuits. Overall, the patent emphasizes a modular approach to display management, enabling efficient code storage and transmission across multiple displays through a unified USB interface.
