Specific embodiment
Referring to Fig. 4, it is the structural representation that LCD data recording tool taken in conjunction of the present invention unifies preferred embodiment
Figure.LCD data recording tool parallel system of the invention mainly includes：Timing controller 41, SPI circuits 42, flash memory
43, and front end is used to connect two SPI connectors 441 and 442 of data recording tool；Timing controller 41 is via SPI
Circuit 42 connects flash memory 43 to read the data in flash memory 43, and the rear end of SPI connectors 441 and 442 is in parallel and via SPI circuits
42 connection flash memories 43 are with the data recordings that will be exported from data recording tool in flash memory 43；SPI connectors 441 and 442
Corresponding electric-controlled switch S1 and S2 is respectively equipped between rear end and SPI circuits 42 to control break-make, electric-controlled switch S1 and S2 origin
Controlled from the control signal A1 and A2 of the data recording tool for being connected to SPI connectors 441 and 442.
During work, coordinate the sequential working of data recording tool by the sequential of control signal A1 and A2, it is each automatically controlled to open
The ON time for closing S1 and S2 is separated from each other so that data recording tool distinguishes burning data, it is to avoid mutually existed between tool dry
Disturb and impedance problems；And there is each electric-controlled switch S1 and S2 the public turn-off time to be read for the timing controller 41
Data in flash memory 43, it is to avoid outside tool influences digital independent.
In this preferred embodiment, timing controller 41, SPI circuits 42 and SPI connectors 441 and 442 are arranged on PCB
On plate 410, flash memory 43 is arranged on XB (horizontal substrate) PCB430；P-gamma/ outside the front end connection of SPI connectors 441
VCOM tools 451, the De-mura tools 452 outside the front end connection of SPI connectors 442 are with burning corresponding data；SECO
Chip 41 is displayed on panel 46 after reading data from flash memory 43.
In this embodiment, the flash chip being parallel-connected to for two SPI connectors on XB is increased on pcb board, and
Each connector rear end will increase electric-controlled switch (S1 and S2), and electric-controlled switch is led when outside provides high level (3.3V voltages)
Turned off during logical, low level (0V voltages), one of connector connects P-gamma/VCOM tools, the connection of another connector
De-mura tools, two tools increase a GPIO (universal input/output) control signal (A1 and A2) respectively, for controlling
Electric-controlled switch.
As shown in Fig. 2 it is LCD data recording tool connection system operation irregularity schematic diagram in the prior art.With
Data recording is carried out to flash memory 23 after the tool 25 of burning data is connected with the SPI connectors 24 on pcb board, works as SECO
Chip 21 need from flash memory 23 read data when, in the case where tool 25 is not pulled out because the tool 25 of outside still with
Flash memory 23 is connected, and causes the impedance of SPI circuits 22 to produce change, and timing controller 21 cannot read correct data and lead
Cause LCD display abnormal, therefore need to pull out tool 25 during digital independent.The present invention also solves this problem simultaneously, this
By setting electric-controlled switch, when data are read, electric-controlled switch can be turned off for invention, it is to avoid outside tool influences digital independent.
The present invention increases the SPI connectors of parallel connection on pcb board, allows multiple SPI tools while being connected to flash memory, is
Avoid mutually there are interference and impedance problems between tool, each SPI connector end respectively increases electric-controlled switch, by it is outside it is high,
The conducting and shut-off of low level signal control parallel connection SPI circuits, by the sequential working of each tool of time cooperation.Need not be frequent
Plug, it is time-consuming, reduce and damage risk；And tool need not be pulled out during digital independent.
Referring to Fig. 6, it is the flow chart of LCD data recording tool parallel method of the present invention, and the method mainly includes：
Step 10, by timing controller via SPI connections flash memory reading the data in flash memory；
Step 20, at least two SPI connectors that front end is used to connect data recording tool rear end it is in parallel and via
SPI connections flash memory is with by data recording to flash memory；
Corresponding electric-controlled switch is respectively equipped between step 30, the rear end of the SPI connectors and SPI circuits to control to lead to
Disconnected, the electric-controlled switch is controlled by the control signal from the data recording tool for being connected to SPI connectors.
Referring to Fig. 5, it is the sequential signal of LCD data recording tool parallel method one of the present invention preferred embodiment
Figure, LCD data recording tool parallel method of the present invention can be better understood from reference to Fig. 4.
During work, the sequential working of the data recording tool is coordinated by the sequential of the control signal, it is each automatically controlled
The ON time of switch is separated from each other so that data recording tool distinguishes burning data, and each electric-controlled switch has public pass
The disconnected time reads the data in flash memory for the timing controller.Producing line can first carry out the tune of P-gamma/VCOM when producing
Entire data is write, and the write-in of De-mura data is then carried out again, and control sequential as shown in Figure 5, signal A1/A2 is at the beginning
Low level, S1/S2 is turned off；When the data after needing to be adjusted to flash chip write-in after the completion of P-gamma/VCOM adjustment,
P-gamma/VCOM tools control A1 signal outputs for high level, electric-controlled switch S1 conductings, and A1 is changed into low after the completion of data write-in
Level, S1 shut-offs；When the write-in of De-mura data is carried out, De-mura tools control A2 signal outputs for high level, automatically controlled to open
S2 conductings are closed, A2 is changed into low level, S2 shut-offs after the completion of data write-in；After being all written in flash chip etc. all data, S1/
S2 is off state, in the case where tool need not be pulled out, when timing controller reads data from flash memory again, and will not
Influenceed by any outside line and cause digital independent to fail.
To sum up, LCD data recording tool parallel method of the present invention and system allow different tools while connecting
It is time-consuming to pcb board, it is to avoid mutually there are interference and impedance problems between tool, and need not frequently plug, reduce and damage
Risk；And tool need not be pulled out during digital independent.
The above, for the person of ordinary skill of the art, can be with technology according to the present invention scheme and technology
Other various corresponding changes and deformation are made in design, and all these changes and deformation should all belong to appended right of the invention
It is required that protection domain.
