  • Publication number: 20080238903
    Abstract: An exemplary on-screen display (OSD) controlling system (1) includes an extended display identification data integrated circuit (EDID IC, 12) and a scalar integrated circuit (IC, 13) electrically connected to the EDID IC. The EDID IC includes a read-write part (122). The scalar IC includes a micro-controller unit (MCU, 131). The MCU is configured for processing data of the read-write part of the EDID IC. Because the scalar IC is connected to the EDID IC and can process the data stored in the read-write part, individualized information can be inputted by a user and displayed. Thus, the OSD controlling system can satisfy the demand for customization of an OSD.
