Abstract
The utility model discloses a display for simplifying data information storage circuit. The display comprises a flash memory FLASH circuit. The FLASH circuit is connected with a host computer; and theflash memory FLASH circuit is used for storing the programs in the display and EDID information which is sent to the host computer by the display. The display for simplifying data information storagecircuit provided by the utility model directly utilizes the FLASH circuit for storing programs in the display to store the extended display identification data (EDID) information, thereby simplifyingthe EDID information storage circuit of the display, greatly lowering the production cost of the display, further improving the market competitiveness of the display, and having significant production and practical meaning.
Description
Technical field
The utility model relates to the display technology field, particularly relates to a kind of display of reduced data information storage circuit.
Background technology
Continuous development along with China's science and technology, domestic electric appliances such as computing machine, televisor, video camera, camera are more and more universal in people's daily life, people often use a computer and understand the information of outside and learn, and computing machine has become people's indispensable ingredient of living.
At present, all be equipped with computing machine in most of family,, on display, shown then, realized the purpose that allows people learn and use by on main frame, storing a large amount of message files.
To carry out good data between graphoscope and the main frame and communicate by letter in order to allow, display need be transferred to extending display identification data (the Extended DisplayIdentification Data of main frame, EDID) information, this EDID information is the normal data information that display is transferred to main frame, comprises data messages such as can receiving capable field frequency scope, production firm, date of manufacture, product ID, product type, typical display mode and parameter thereof.
At present, in graphoscope, storage scheme to EDID information is: use independent EEPROM (Electrically Erasable Programmable Read Only Memo) (Electrically Erasable Programmable Read-OnlyMemory, EEPROM) circuit is stored, providing main frame to write and read operation, this eeprom circuit complexity, cost is higher, increase the production cost of graphoscope, had influence on the market product competitive power of display.
Also do not occur a kind of graphoscope at present, it can simplify the EDID information storage circuit of display, thereby reduces the production cost of display.
The utility model content
In view of this, the purpose of this utility model provides a kind of display of reduced data information storage circuit, this display directly uses and is used for stored program flash memory FLASH circuitry stores EDID information in the display, simplified the extending display identification data EDID information storage circuit of display, greatly reduce the production cost of display, and then improved the market product competitive power of display, be of great practical significance.
For this reason, the utility model provides a kind of display of reduced data information storage circuit, include flash memory FLASH circuit, this FLASH circuit is connected with main frame, described flash memory FLASH circuit, the program that is used for iatron, and iatron need send to the EDID information of main frame.
Preferably, described flash memory Flash circuit includes:
The procedure stores electronic circuit is connected with main frame, is used for the program of iatron;
The sub-road of extending display identification data EDID information stores is connected with main frame, is used for the EDID information that iatron need send to main frame.
Preferably, described flash memory Flash circuit is connected by the main frame of a pressure drop diode with the outside.
The technical scheme that is provided by above the utility model as seen, compared with prior art, the utility model provides a kind of display of reduced data information storage circuit, this display directly uses and is used for stored program FLASH circuitry stores EDID information in the display, simplified the EDID information storage circuit of display, greatly reduce the production cost of display, and then improved the market product competitive power of display, be of great practical significance.
Description of drawings
The structural representation of the display of a kind of reduced data information storage circuit that Fig. 1 provides for the utility model.
Embodiment
In order to make those skilled in the art person understand the utility model scheme better, the utility model is described in further detail below in conjunction with drawings and embodiments.
The structural representation of the display of a kind of reduced data information storage circuit that Fig. 1 provides for the utility model.
Referring to Fig. 1, the utility model provides a kind of display of reduced data information storage circuit, and this display includes flash memory FLASH circuit 100, and this FLASH circuit 100 is connected with main frame;
Described flash memory FLASH circuit 100 be used for the program of iatron, and iatron need send to the EDID information of main frame.
On the specific implementation, flash memory Flash circuit 100 includes:
Procedure stores electronic circuit 101 is connected with main frame, is used for the program of iatron;
The sub-road 102 of extending display identification data EDID information stores is connected with main frame, is used for the EDID information that iatron need send to main frame.
Need to prove, requirement on the specific implementation, under the situation that display Monitor power supply is not powered, main frame needs still can to read EDID information, and the eeprom circuit of the existing storage EDID information 5V voltage that provides that uses a computer is powered; And for the technical solution of the utility model, owing to adopt flash memory Flash circuit 100 to come iatron need send to the EDID information of main frame, the 5V voltage that need earlier computing machine be provided is 3.3V by the pressure drop diode step-down of a 0.3V, give the Flash circuit then, therefore display Monitor of the present utility model also can give Flash circuit normal power supply under the unconnected situation of power supply, finishes reading and writing of EDID information.
In sum, compared with prior art, the utility model provides a kind of display of reduced data information storage circuit, this display directly uses and is used for stored program FLASH circuitry stores EDID information in the display, simplified the EDID information storage circuit of display, greatly reduce the production cost of display, and then improved the market product competitive power of display, be of great practical significance.
The above only is a preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
