Description
Technical field
The present invention relates to the display production field, relate in particular to a kind of intelligent EDID method for burn-recording.
Background technology
Two big types of burning display EDID (Extended Display Identification Data Standard of main existence in the prior art; The extending display identification data) method: one, embedded EDID data in display software the inside; Do not carry out online burning during plant produced, or just upgrade wherein partial information.Two, online through each interface line burning one by one.Wherein first method requires the display software engineer to understand the relevant regulations and the EDID data layout of factory fully.Facts have proved to require the slip-stick artist to understand the regulation of numerous factories and be not easy to accomplish, and cause error easily; Second method is the method for present main flow, but along with the increasing of present monitor signal interface, the workload of production line also correspondingly increases.Such as before display have only a VGA (Video Graphic Array, show drawing array) interface, only need burning once; And present display generally has two or three interfaces (like VGA interface, DVI interface, HDMI interface etc.), and then wants burning two to three times, and the time of cost is elongated relatively, influences production efficiency.
Summary of the invention
In order to improve the efficient of display production line burning EDID, the present invention proposes a kind of intelligent EDID method for burn-recording.
The technical scheme that the present invention adopts is that a kind of intelligent EDID method for burn-recording is characterized in that, comprising:
Last electro-detection step, the line and the power-up state of detection liquid crystal display drive plate;
Analytical procedure is analyzed the group number of the EDID data of treating burning and the difference of respectively organizing between the EDID data and whether is met the known difference rule;
The burning step is selected corresponding burning scheme according to analysis result and is carried out burning;
Checking procedure carries out verification to the data after the burning completion.
Said known difference rule comprises:
Each is organized the EDID data and has only simulation/Data Labels position and verification different with the position;
Each is organized the EDID data and has only name of product position and verification different with the position;
Each is organized the EDID data and has only rise time position and verification different with the position;
Each is organized the EDID data and has only serial number bit and verification different with the position;
More than all situations that permutation and combination produced of four kinds of situation.
Last electro-detection step specifically comprises:
Computing machine sends sense command and gives liquid crystal display driver plate, if do not receive the response message of liquid crystal display drive plate feedback, then points out corresponding information;
If can receive the response message of liquid crystal display drive plate feedback, then execution analysis step.
Analytical procedure specifically comprises:
Computing machine is at first analyzed the EDID data of treating burning and whether is had only one group, if having only one group, directly carries out the burning step;
If surpass one group, whether the difference of then analyzing between several groups of EDID data treating burning meets the known difference rule, carries out the burning step again.
The burning step specifically comprises:
Have only one group if treat the EDID data of burning, then these EDID data are write corresponding storer;
Surpass one group if treat the EDID data of burning, and the difference between several groups of EDID data do not meet the known difference rule, then write corresponding storer to the EDID data one by one;
If the EDID data of treating burning are above one group; And the difference between several groups of EDID data meets the known difference rule; Then one group of EDID data is write corresponding storer, and this rule is sent to master chip, master chip loads the EDID data in the aforementioned memory; Generate new data after changing difference-byte according to rule, and write in other corresponding storeies.
In the said burning step; If the EDID data of treating burning are above one group; And the difference between several groups of EDID data does not meet the known difference rule, then through an interface several groups of EDID data is transferred to master chip one by one, indirectly the EDID data is write corresponding storer one by one by master chip.
In whole EDID data burning process, computing machine only is connected with an interface of liquid crystal display drive plate.
Adopt the communication modes of IIC or DDC/CI between computing machine and liquid crystal display drive plate.
Intelligent EDID method for burn-recording of the present invention utilizes Computer Analysis to treat the EDID data of burning, selects corresponding burning scheme to carry out burning according to the different situations of treating burning data, and the applicability of method for burn-recording is more extensive, makes the burning production line intelligent more.When one group of EDID data burning behind storer; Master chip through the liquid crystal display drive plate upgrades the data of burning; Write then in other corresponding storeies, reduced harsh requirement, drop to the Data Update fault rate of distinct interface minimum the software engineer; And only need use the once burning task that just can accomplish total interface of interface burning; Removed the loaded down with trivial details step that will connect total interface and carry out burning one by one from, reduced the working time of burning work, the reliability of production efficiency and burning is significantly improved.
