Abstract

The invention discloses an expanded display and identification data recording method and a display device. The expanded display and identification data recording method is suitable for the display device. The display device is provided with at least one expanded display and identification data chip, a microcontroller chip, a flash memory chip and an electronic erasable and programmable read only memory. The method comprises the steps that first expanded display and identification data corresponding to the expanded display and identification data chip is read in a firmware stored by the flash memory chip; the display device is powered; and the microcontroller chip automatically reads the first expanded display and identification data in the firmware in the corresponding expanded display and identification data chip to become second expanded display and identification data. The method and the display device can reduce the manpower, save the recording time and lower the cost.

Description

technical field [0001] The present invention relates to a recording method, and in particular, to a recording method and a display device of extended display identification data. Background technique [0002] In order to support the Extended Display Identification Data (EDID) standard of the Video Electronics Standards Association (VESA), the general practice is to use the projector, monitor, and Each input terminal of a display device such as a digital television uses an electronically erasable programmable read only memory (EEPROM for short) to store the extended display identification data content table of the corresponding input terminal . In the process of mass production, in order to speed up the operation, part of the information required to expand the display identification data content table, such as the manufacturing date and serial number of the display device, are read from the barcode, and then burned to the EEPROM together with other content, but Different mo...
