Abstract
The utility model relates to a display device with EDID information stored in an MCU, which comprises the MCU and a VGA card of the display device, and is characterized in that the MCU is connected with the VGA card via an I2C bus; and a flash memory module used for storing the EDID information is arranged in the MCU. The utility model has the EDID information stored in the MCU in the display device, thereby reducing an external EEPROM of the display device and related circuits, lowering the cost, and resulting in higher marketable value.
Description
Technical field
The utility model relates to a kind of EDID data and is located at display device among the MCU.
Background technology
As shown in Figure 1, existing LCD machine EDID is placed among the plug-in EEPROM, during burning EDID by EDID replication tool and EEPROM direct communication.There is following shortcoming like this: 1, plug-in EEPROM is set causes cost to increase; 2, interface EDID such as VGA/DVI need distinguish burning, increases during worker; 3, circuit is established plug-in EEPROM, the miniaturization of restriction mainboard, and many parts can cause bad risk to increase.
Summary of the invention
In order to overcome above-mentioned defective, the purpose of this utility model provides a kind of EDID data and is located at display device among the MCU, and this device utilizes the flash memory module storage EDID data among the MCU, has saved the Peripheral storage circuit of display device.
For achieving the above object, the utility model adopts following scheme to solve: a kind of EDID data is located at the display device among the MCU, comprises the MCU and the display card of display device, it is characterized in that: described MCU is connected with display card by the I2C bus; Described MCU is built-in with the flash memory module that is used to deposit the EDID data.
The beneficial effects of the utility model are:
1, special-purpose EEPROM and peripheral loop thereof of depositing EDID, the waste of having saved EEPROM and peripheral loop materials and parts thereof have been cancelled;
2, interface EDID of burning, other interface EDID changes by FW, saves processing procedure man-hour;
3, mainboard line design cancellation EEPROM point position is easy to the pcb board miniaturization, reduces bad risk.
Description of drawings
Fig. 1 be habit display device partial circuit principle schematic.
Fig. 2 is the utility model partial circuit principle schematic.
Embodiment
Below in conjunction with drawings and Examples the utility model is described further.
As shown in Figure 2, the utility model provides a kind of EDID data to be located at display device among the MCU, comprises the MCU and the display card of display device, it is characterized in that: described MCU is connected with display card by the I2C bus; Described MCU is built-in with the flash memory module that is used to deposit the EDID data.
Specifically, the utility model in MCU, has effectively been saved the programming of EDID data to be specifically designed to and has been deposited EEPROM and peripheral loop thereof by the flash memory module that the MCU in described display device is provided for depositing the EDID data.
In addition, in the utility model preferred embodiment, described display device comprises LCD and liquid crystal TV set.
The above only is preferred embodiment of the present utility model, and all equalizations of being done according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
