Problems solved by technology

[0003] The disadvantage of the above method is that as the image signals that the display device can support become more and more diversified, more and more electronically erasable read-only memories need to be embedded in the display device, which may lead to an increase in cost or It is a problem showing that there are too many parts in the device

Abstract

An integrated circuit capable of providing extension display sign data based on image signals is suitable for a display comprising a plurality of image input ports. Each image input port is used for receiving one of various image signals sent by an electronic device. The integrated circuit comprises an extension display sign data storage unit used for storing a plurality of extension display sign data corresponding to the various image signals, a plurality of switches which are respectively connected with the image input ports through buses and a switch control unit used for judging states of the image input ports and recognizing types of the image signals. When the image input ports are in action states, the switch control unit can open the switches connected with the image input ports of the received image signals according to the types of the image signals to enable the electrode device to read extension display sign data corresponding to the image signals from the extension display sign data storage unit through the image input ports and the switches.

Description

technical field [0001] The invention relates to an integrated circuit, in particular to an integrated circuit providing extended display sign data based on image signals. Background technique [0002] In the past, in order to allow electronic devices (for example, computer hosts) to obtain information such as the signal range allowed by the connected display devices (for example, liquid crystal displays), display device manufacturers would embed several electronic erasable Read-only memory (Electrically-Erasable Programmable Read-Only Memory, EEPROM). Each EEPROM is respectively used for storing an Extended Display Identification Data (EDID). Each extended display logo data corresponds to a video signal, such as a Digital Visual Interface (DVI) signal or a High Definition Multimedia Interface (HDMI) signal. The logo data of each extended display includes information such as screen resolution and scanning frequency that the display device can support. [0003] The disadvan...
