Embodiment Construction

[0009] The present invention will be further described below in conjunction with the accompanying drawings and implementation examples.

[0010] Such as figure 2 As shown, the present invention provides a display EDID burning method, which is characterized in that: when the display EDID is burning, first send the VGA EDID data of the display to the display MCU software, when the VGA EDID data received by the MCU, the data After saving to the corresponding storage location, modify the bytes with differences between the VGA EDID data and DVI EDID data to DVI EDID data, and copy the modified DVI EDID data to the EDID storage location of the DVI interface.

[0011] The VGA EDID data of the display is sent to the MCU software of the display through I2C communication.

[0012] In a preferred implementation example of the present invention, the liquid crystal display of the PHILIPS 220E1 model has two interfaces of VGA and DVI, and the EDID data of VGA and DVI provided by the custo...

Abstract

The invention relates to a method for recording a display EDID, which is characterized in that when the display EDID is recorded, the VGA EDID of a display is transmitted to display MCU software; when an MCU receives the VGA EDID and stores the data in the corresponding storage position, a different byte between the VGA EDID and DVI EDID is modified into DVI EDID, and the modified DVI EDID is copied to the position on a DVI interface, where the EDID is stored. The invention simplifies the EDID recording process and improves the production efficiency and the quality of the display.

Description

technical field [0001] The invention relates to the application of a display EDID burning method and the field of display production. Background technique [0002] As is known, if the display has multiple input sources, each source needs to burn the corresponding EDID (Extended Display Identification Data Standard) data. For a monitor with VGA, DVI and HDMI, both the VGA interface and DVI interface need to burn the corresponding EDID data. The burning process is as follows: figure 1 shown. In the manufacturing process of the display factory, it takes about 3S to burn the EDID. The time required for multiple interfaces is (3s*number of interfaces), which affects the production efficiency of the production line. And when programming each interface, make sure that the output SN numbers are consistent. Contents of the invention [0003] In order to overcome the deficiencies of the above-mentioned technologies, the object of the present invention is to provide a method for ...
