Description
Technical field
The present invention relates to a kind of liquid crystal display EDID method for burn-recording.
Background technology
Liquid crystal display EDID burning is necessary production process in production process of liquid crystal displays, due to liquid crystal display
The difference of interface, recordable time can be different.The complicated display of current function gets more and more, and interface at most recordable time is long,
Excessive manpower and erect-position can be taken, production cost is higher.
Content of the invention
In view of this, it is an object of the invention to provide a kind of liquid crystal display EDID method for burn-recording, manpower, lifting are reduced
Reduce production cost while efficiency.
For achieving the above object, the present invention adopts the following technical scheme that：A kind of liquid crystal display EDID method for burn-recording, it is special
Levy and be, comprise the following steps：
Step S1：To treating electricity on the liquid crystal display of burning, carry out the first time burning of EDID data；
Step S2：The described liquid crystal display treating burning is connected to main frame, described main frame transmits Sequence Number and week in time does not believe
Cease to the described liquid crystal display treating burning, the described LCDs treating burning carry out second burning of EDID data, more
The serial number of new EDID data and week in time other information；
Step S3：Main frame sends the instruction obtaining serial number and week in time other information, described band to the liquid crystal display treating burning
The LCDs of burning return serial number and week in time other information to main frame after receiving instruction；
Step S4：The serial number of the serial number of main frame contrast transmission and week in time other information and passback all other information with the time, if
Identical, then carry out step S5, otherwise point out burning failure and return to step S1；
Step S5：Prompting burning success, carries out the burning of next liquid crystal display.
Further, in described step S1, treat that the liquid crystal display of burning prestores EDID data.
Further, the Serial No. main frame in described step S2 passes through online reading bar code acquisition, does not believe in week in time
Cease and be transformed by the date being manually entered for main frame.
Further, described main frame is industry PC.
The present invention compared with prior art has the advantages that：
1st, prior art transmits all EDID data, and volume of transmitted data is big, transfer sequence number of the present invention and week in time other Information Number
Little according to measuring；
2nd, when transmitting many parts of EDID data, transmission time is long, and no matter the present invention transmits how many parts of EDID data for prior art, passes
The defeated time is all the same, and more shorter than prior art；
3rd, prior art is in burning multiple EDID interface, less efficient, needs more manpower and erect-position, and the present invention only transmits one
Part serial number and week in time other information, efficiency is higher.
Brief description
Fig. 1 is prior art burning process schematic.
Fig. 2 is present invention first time burning process schematic.
Fig. 3 is second burning process schematic of the present invention.
Fig. 4 is the complete EDID schematic diagram data of one embodiment of the invention.
Specific embodiment
Below in conjunction with the accompanying drawings and embodiment the present invention will be further described.
Refer to Fig. 1, in prior art, industry PC reads, by parallel port, the renewal that bar code carries out EDID data, and will
All of EDID data sends to treats that the liquid crystal display of burning carries out burning.During being somebody's turn to do, the data volume of transmission is excessive, takes
Longer.
The present invention provides a kind of liquid crystal display EDID method for burn-recording, comprises the following steps：
Step S1：Refer to Fig. 2, to treating electricity on the liquid crystal display of burning, carry out the first time burning of EDID data, wherein,
Treat that the liquid crystal display of burning prestores EDID data；
Step S2：Refer to Fig. 3, the described liquid crystal display treating burning is connected to main frame, described main frame passes through online reading
Bar code obtains serial number and sends it to described after the main frame date being manually entered is converted into week in time other information
Treat the liquid crystal display of burning, the described LCDs treating burning carry out second burning of EDID data, update EDID number
According to serial number and week in time other information；
Step S3：Main frame sends the instruction obtaining serial number and week in time other information, described band to the liquid crystal display treating burning
The LCDs of burning return serial number and week in time other information to main frame after receiving instruction；
Step S4：The serial number of the serial number of main frame contrast transmission and week in time other information and passback all other information with the time, if
Identical, then carry out step S5, otherwise point out burning failure and return to step S1；
Step S5：Prompting burning success, carries out the burning of next liquid crystal display.
Further, described main frame is industry PC.
It is noted that the application and technology contrast before, do not increase equipment, but treat the liquid crystal display of burning
The function of device and industry PC claims：
A, ISP card：Also it is burning jig, be that PC is communicated with liquid crystal display（Burning）Interface hardware, major function is by
Level conversion and interface expand；Interface mainly has LPT（Connect PC）, VGA mouth（It is connected with the liquid crystal display of VGA mouth）、
DVI mouth, HDMI mouth.During communication, voltage and liquid crystal display due to PC interface can be inconsistent, during communication, need IC to carry out turning
Change；Its hardware components is not changed in substantially；
B, treat the liquid crystal display of burning：Software is required to enable following function：All EDID data can be stored；Can be for the first time
The EDID of automatic burning total interface during upper electricity；The serial number of EDID can be updated according to the requirement of industry PC and not believe in week in time
Breath；
C, industry PC：Using parallel port simulation IIC communication, hardware components its be not changed in.
EDID data explanation：VGA is 128Byte, and DVI has two kinds of 128Byte and 256Byte, and HDMI exists for 256Byte.
In production of liquid crystal displays, every display record recordable time of customer requirement and serial number, substantially adopt in producing at present
The mode of online burning（Add serial number during online wanding, update EDID）.
Prior art burning all EDID data, the application first powers on also burning all EDID data（But it is not required to people
Power and erect-position）；
This motion only needs burning low volume data (to be specifically shown in the double underline part of Fig. 4, wherein " * " representative in second burning
Variable part), VGA is 19Byte/128Byte, and DVI is 19Byte/128Byte or 19Byte/256Byte, and HDMI is
19Byte/256Byte.
It is compared with the prior art table for the application described in table 1 below（Required manpower, equipment and erect-position are with 600/hour for mark
Quasi- calculating）
Table 1：
| Burning data amount | Averagely every part HDMI recordable time | Burning total time | Need manpower | Need equipment | Erect-position | |
| Prior art | 768Byte | 2.4s | 7.2s | 3 people | 3 ISP cards, 3 industry PCs | 3 stations |
