Abstract
The invention discloses a method and device for automatically regulating flickers of a liquid crystal display module. A flicker measurement module is used for measuring the flicker value of the liquid crystal display module in real time, a main control module is used for judging the magnitude relation of the actual measured flicker value and a standard flicker value, if the actual measured flicker value is larger than the standard flicker value, parameters of a display drive chip of the liquid crystal display module are changed, if the actual measured flicker value is smaller than the standard flicker value, the current actual measured flicker value is used as a new standard flicker value, measurement is repeated until the actual measured flicker value is no longer smaller than the standard flicker value, and the current standard flicker value is fixed. The device is simple in structure, convenient to operate, and capable of replacing manual regulation, work efficiency is improved, workload of operators is lowered, accuracy of flicker value regulation is high, and the method and device are suitable for being popularized and used in a large range.
Description
Technical field
The present invention relates to technical field of liquid crystal display, particularly a kind of flicker automatic adjusting method and device of liquid crystal display module.
Background technology
Flicker value is one of important parameter of liquid crystal display module.Current present situation is that the flicker value of liquid crystal display module mostly is artificial adjustment, by manual adjustments register parameters, thereby realizes the adjustment of carrying out flicker value.This efficiency of adjusting mode is lower.
Summary of the invention
For the lower present situation of regulated efficiency of the flicker value of current liquid crystal display module, applicant, through Improvement, now provides a kind of flicker automatic adjusting method and device of liquid crystal display module, increases work efficiency, and alleviates the workload of operator.
Technical scheme of the present invention is as follows:
The invention provides a kind of flicker automatic adjusting method of liquid crystal display module, with flicker measurement module, measure in real time the flicker value of liquid crystal display module, and the flicker value recording is delivered to main control module; A default standard flicker value in main control module, by the magnitude relationship of main control module judgement actual measurement flicker value and standard flicker value; If actual measurement flicker value is greater than standard flicker value, main control module makes display control module action, to the display driver chip of liquid crystal display module, sends instruction, changes its parameter, and continues to measure the flicker value of liquid crystal display module; If actual measurement flicker value is less than standard flicker value, using current actual measurement flicker value as new standard flicker value, and the flicker value of liquid crystal display module is measured in continuation; Repeat above-mentioned steps, until actual measurement flicker value is no longer less than standard flicker value, by main control module, display control module is moved, to the display driver chip of liquid crystal display module, send instruction, burned current standard flicker value is as the setting flicker value of this liquid crystal display module.
The present invention also provides a kind of flicker automatic regulating apparatus of liquid crystal display module, comprises flicker measurement module, main control module and display control module; Described flicker measurement module connects liquid crystal display module and main control module, for reading the flicker value of liquid crystal display module and being delivered to main control module; Described main control module connects flicker measurement module and display control module, for judging the actual measurement flicker value sent here by flicker measurement module and the magnitude relationship of its internal preset standard flicker value, and to display control module, sends instruction according to judged result; Described display control module connects the display driver chip of main control module and liquid crystal display module, for make the parameter change of the display driver chip of liquid crystal display module according to the instruction of main control module, thus the flicker value of change liquid crystal display module.
Useful technique effect of the present invention is:
Apparatus structure of the present invention is simple, easy to operate, can replace artificial adjustment, increases work efficiency, and alleviates the workload of operator, and the accuracy of adjustment flicker value is high, is suitable for large application scope.
Advantage of the present invention will provide in embodiment description partly below, and part will become obviously from the following description, or recognize by practice of the present invention.
Accompanying drawing explanation
Fig. 1 is apparatus structure schematic diagram of the present invention.
Fig. 2 is method flow diagram of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described further.
Fig. 1 is apparatus structure schematic diagram of the present invention.As shown in Figure 1, apparatus of the present invention comprise: flicker measurement module 1, main control module 2 and display control module 3.The core of flicker measurement module 1 is flicker measuring sonde, and it connects object to be adjusted--liquid crystal display module 5 and main control module 2, for reading the flicker value of liquid crystal display module 4, and give main control module 2 by flicker value.The core of main control module 2 is Master control chip, it connects flicker measurement module 1 and display control module 3, for judging by the actual measurement flicker value sent here of flicker measurement module 1 and the magnitude relationship of its internal preset standard flicker value, and according to judged result, control display control module 3 and move.Display control module 3 connects the display driver chip of main control module 2 and liquid crystal display module 4, for make the parameter change of the display driver chip of liquid crystal display module 5 according to the instruction of main control module 2, thus the flicker value of change liquid crystal display module 4.Flicker measurement module 1 of the present invention, main control module 2 and display control module 3 are commercial goods.
Adopt process flow diagram that said apparatus realizes the inventive method as shown in Figure 2.First (step 1) is measured in real time the flicker value of liquid crystal display module 4 with flicker measurement module 1, and the flicker value recording is delivered to main control module 2.Then (step 2), in the interior preset standard flicker value of main control module 2, by the magnitude relationship of main control module 2 judgement actual measurement flicker value and standard flicker value; If actual measurement flicker value is greater than standard flicker value, main control module 2 makes display control module 3 action, to the display driver chip of liquid crystal display module 5, sends instruction, changes chip parameter, change register value wherein, and get back to the flicker value that step 1 continues to measure liquid crystal display module 4; If actual measurement flicker value is less than standard flicker value, current actual measurement flicker value is saved as to new standard flicker value, and get back to the flicker value that step 1 continues to measure liquid crystal display module 4.Repeatedly repeat above-mentioned steps 1～2, until follow-up actual measurement flicker value is all greater than standard flicker value, show that standard flicker value has reached minimum, (step 3) makes display control module 3 actions by main control module 2, display driver chip to liquid crystal display module 4 sends instruction, and burned current standard flicker value is as the setting flicker value of this liquid crystal display module 4.Fixing flicker value, and start display frame, for subsequent examination.
Above-described is only the preferred embodiment of the present invention, the invention is not restricted to above embodiment.Be appreciated that the oher improvements and changes that those skilled in the art directly derive or associate without departing from the basic idea of the present invention, within all should thinking and being included in protection scope of the present invention.
