Abstract
The present invention relates to a kind of method for burn-recording of liquid crystal display electricity consumption data, it is characterized by: by electricity consumption data and display function data compilation at same software, the software is burned onto flash chip again, after complete machine assembling, the flash chip is sent a command to by the control chip of mainboard, electricity consumption data is burned onto driving voltage chip.Present invention reduces manpowers and equipment cost, and reduce the risk of burning omission.
Description
Technical field
The present invention relates to a kind of method for burn-recording of liquid crystal display electricity consumption data.
Background technique
Use can compile driving voltage IC (Power IC) on present industry display pannel (Panel) circuit gradually
The IC of journey, because the technology can by 7 Power Data bytes to Power IC of burning come the driving of accurate fine tuning Panel
Voltage V_lcd, Vcom, Gamma voltage and horizontal-drive signal etc. realize the stabilization of performance.
Therefore, display producer is all currently to introduce the method for burning Power Data before panel production to realize
Burning function, the existing burning mode of industry have the following two kinds:
1, before Panel PCB carries out SMT patch, Power Data is burnt to Power IC with automatic recording device
Afterwards, it then fits on pcb board.
2, first Power IC progress SMT is fitted on pcb board, then by carrying out Power Data to every plank by hand
Burning.
However first method needs to develop automatic recording device, cost of equipment is high, it is also necessary to which a manpower goes to place
With remove chip, manpower and cost of equipment can not save；Although automatic recording device of the second method without developing valuableness,
Not only speed is slow for manual burning, it also occur that omitting, all has a great impact to production capacity and quality, if in order to adapt to a large amount of lifes
It produces, also needs to add manpower.
Summary of the invention
In view of this, reducing manpower the purpose of the present invention is to provide a kind of method for burn-recording of liquid crystal display electricity consumption data
And equipment cost, and reduce the risk of burning omission.
To achieve the above object, the present invention adopts the following technical scheme: a kind of method for burn-recording of liquid crystal display electricity consumption data,
It is characterized in that: electricity consumption data and display function data compilation is burned onto flash chip at same software, then by the software
In, after complete machine assembling, the flash chip is sent a command to by the control chip of mainboard, electricity consumption data is burned onto driving electricity
It presses in chip.
Further, the specific steps are as follows:
Step S1: the driving voltage chip of the electricity consumption data initial value of default 7 bytes is directly conformed into panel PCB
On；
Step S2: in mainboard assembling, by the electricity consumption data of 7 bytes with display function data compilation at same soft
Part, and the software is burned onto flash chip；
Step S3: it when complete machine assembles, to 220V alternating current on display, is sent a command to by the control chip of mainboard described
Flash chip reads the electricity consumption data of 7 bytes；
Step S4: the electricity consumption data of comparison 7 bytes and the electricity consumption data initial value of preset 7 bytes, if not
Together, the electricity consumption data of flash chip is burned onto driving voltage chip, otherwise the electricity consumption data in driving voltage chip is kept not
Become.
Compared with the prior art, the invention has the following beneficial effects: the present invention is not necessarily to without additional exploitation recording device
Increase this processing procedure of burning electricity consumption data in the production line, to reduce a large amount of manpower and equipment cost, and reduces burning
Record the risk omitted.
Detailed description of the invention
Fig. 1 is flow chart of the method for the present invention.
Specific embodiment
The present invention will be further described with reference to the accompanying drawings and embodiments.
The present invention provides a kind of method for burn-recording of liquid crystal display electricity consumption data, it is characterised in that: by electricity consumption data and display
Performance data is compiled into same software, then the software is burned onto flash chip, after complete machine assembling, by the control of mainboard
Chip sends a command to the flash chip and electricity consumption data is burned onto driving voltage chip.
Please refer to Fig. 1, the specific steps are as follows:
Step S1: the driving voltage chip of the electricity consumption data initial value of default 7 bytes is directly conformed into panel PCB
On, the burning of electricity consumption data is all no longer carried out to driving voltage chip before and after fitting, after fitting, carries out the welding of next step,
Then carry out liquid crystal display die set assembling, because driving voltage chip factory when built in 7 bytes electricity consumption data initial value,
So even if the electricity consumption data new without burning, will not influence the basic function of panel；
Step S2: in mainboard assembling, by the electricity consumption data of 7 bytes with display function data compilation at same soft
Part, and the software is burned onto flash chip；
Step S3: when complete machine assembles, 220V alternating current is plugged to display, institute is sent a command to by the control chip of mainboard
Flash chip is stated to read the electricity consumption data of 7 bytes and read the electricity consumption data initial value of preset 7 bytes simultaneously；
Step S4: the electricity consumption data of comparison 7 bytes and the electricity consumption data initial value of preset 7 bytes, if not
Together, the electricity consumption data of flash chip is burned onto driving voltage chip, otherwise the electricity consumption data in driving voltage chip is kept not
Become.
The foregoing is merely presently preferred embodiments of the present invention, all equivalent changes done according to scope of the present invention patent with
Modification, is all covered by the present invention.
Claims (1)
1. a kind of method for burn-recording of liquid crystal display electricity consumption data, it is characterised in that: by electricity consumption data and display function data compilation
