Description
Technical field
The present invention relates to OLED display field, especially a kind of OLED TV guard method.
Background technique
OLED (Organic Light-Emitting Diode) TV is taken as all new generation OLED display screen skill
The TV of art has not needed backlight module, and rgb color signal is directly shown by OLED diode, in the institute for possessing LED television
While having characteristics and advantages, also with gorgeous color more true to nature, broader angle of visibility, the performance of more ultimate attainment black field and
Unlimited contrast, and the blue optical band generated is concentrated mainly at 460nm, is not belonging to harmful blue light, energy is smaller, to people
Eye harm is very little.
But the limitation of the self-luminous organic material used due to oled panel and the limitation of manufacture craft, there are following two
Aspect problem: if abnormal or short circuit occurs in the diode of 1. OLED screen curtains, if being easy to cause screen since its characteristic continues to use
Permanent damage even burn-in, therefore if detect screen it is abnormal if need locking system, light screen can not, return repair in shop
It can just be continued to use after multiple exception.2. during use, right if playing tableaux, high brightness picture, height for a long time
Than degree picture, ghost will be left on the screen, and with using the time longer, this ghost phenomena can be increasingly severe.
Summary of the invention
In view of this, the purpose of the present invention is to propose to a kind of OLED TV guard method, it being capable of effective protection screen.
The present invention is realized using following scheme: a kind of OLED TV guard method, specifically includes the following steps:

Enter step S2；It is more than the first preset time when the continuous use time for detecting screen, then enters step S3；Otherwise continue to screen
Curtain carries out real-time monitoring, until shutdown；
Step S2: it is default to judge whether exceptional condition meets, system enters standby mode if meeting, and locks system；
Step S3: the continuous use time of current screen is judged whether more than the second preset time, if so, carrying out to screen high
The ghost of grade is eliminated；Otherwise primary ghost is carried out to screen to eliminate.
Further, the system is that the background service program of self-starting realizes the reality to screen state by design booting
When monitor.
Further, step S2 specifically includes the following steps:
Step S21: judge that last time using whether there is exception, if then entering step S22, otherwise enables anomalous counts device reset；
Step S22: judging whether that detecting screen within continuous 1 second has Error signal, if then entering step S26, otherwise enters step
Rapid S24；Wherein the detecting of Error signal can be realized by the thread created in system software；
Step S24: judging whether booting more than 10 seconds, if then entering step S25, otherwise return step S22；
Step S25: judge whether that continuous 500ms detects the abnormal signal of ON RF Done, if so, entering step S26；It is no
Then return step S22；Wherein, the abnormal signal of the ON RF Done is " ready for " signal, that is, detects inside screen
After each condition is ready for, chip could export VBO signal to screen；
Step S26: anomalous counts device cumulative 1 is enabled；
Step S27: judging whether anomalous counts device is more than or equal to 3, if so, locking television system and shutting down；Otherwise it directly closes
Machine.
Further, first preset time is 4 hours, and second preset time is 1200 hours.
Further, described that primary ghost elimination is carried out to screen in step S3 specifically: control remote controler shutdown,
System executes the control to the driving voltage of screen transistor, using the ergodic algorithm to each pixel, carries out fast charging and discharging,
To achieve the purpose that eliminate slight ghost, system enters really standby after being finished.
Further, described that advanced ghost elimination is carried out to screen specifically: remote controler shutdown, system in step S3
The image compensation to screen is executed, screen cooling first, and screen temperature is detected by screen built-in sensors, when temperature reaches
When preset value, screen transistor is carried out charge and discharge and resetted to operate, to reach the mesh for eliminating serious ghost, after being finished
System enters really standby.
Preferably, the present invention using Dynamic Search Algorithm to OLED TV carry out abnormity detecting, if systems scan to extremely,
Then screen locking, to prevent screen from permanent damage occur and ensure product and user security.The present invention is adjusted using adaptive simultaneously
Whole algorithm carries out the compensation of screen ghost and amendment to OLED TV, and it is right to solve broadcasting tableaux, high brightness picture, height for a long time
Than ghost caused by degree picture.It improves the service life of screen and guarantees the lasting clarity of screen.
Compared with prior art, the invention has the following beneficial effects: method provided by the invention can thoroughly avoid screen
There is permanent damage and the TV use of OLED is allowed to become safer.The compensation for eliminating OLED video screen ghost is provided simultaneously
Modification method by detecting real-time user using the time that uses of screen, and does the residual of primary to screen as judgment basis
Shadow is eliminated or advanced ghost is eliminated, still shining so as new after screen long-time use to guarantee.
