Method for conformity of bar code information and spreading display identification data

Abstract

The invention provides a method for integrating bar code information and extended display identification data (EDID). Firstly, the bar code information is input and stored in a first storage device temporarily. A prestored bar code rule and a prestored check code are read from a second storage device; the bar code rule defines the relevant data of a plurality of codes contained in the bar code information. The codes contained in the bar code information are respectively stored in corresponding storage space in the first storage device according to the bar code rule. Whether the specific code of the bar code information is in accordance with the check code is judged; when the specific code of the bar code information is in accordance with the check code, the EDID prestored by an EDID rewriter is read and integrated with the codes of the bar code information so as to generate new EDID. At last, a display is written according to the new EDID.

Description

technical field [0001] The invention relates to a data integration method, especially a method suitable for integrating barcode information and extended display identification data. Background technique [0002] With the popularization of computer technology, the function of plug and play has become an essential function of computer peripherals. In terms of displays, the Video Electronics Standards Association (VESA) is responsible for promoting and developing major display and display interface standards to ensure interoperability. Extended Display Information Data (EDID for short) is a standard data format formulated by Video Electronics Standards Association (VESA) for displays. EDID contains the basic data of a display, such as: vendor information, maximum image size, color characteristics, usage frequency restrictions, etc. The EDID is recorded in the display and used to communicate with a host computer to achieve the plug and play function. [0003] Over the past te...

Problems solved by technology

[0005] However, in the past, reading, writing, and editing EDIDs were performed by relying on the aforementioned bulky PC architecture, which not only caused troubles in terms of equipment costs and maintenance costs, but also caused EDIDs to be unable to be updated in real time in terms of storage media, and even data flow direction Serious management problems such as difficult to master

At the same time, for different types of monitors or monitors with different batch numbers, the factory workers need to prepare different barcode information and EDID, which not only increases the complexity of the operation, but also makes it difficult to prevent improper use of EDID from being burned into the monitor
