Description of drawings
The invention will be further described below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is that solution display screen of the present invention shows unusual method flow diagram;
Fig. 2 is that solution display screen of the present invention shows unusual system architecture diagram.
Embodiment
In order to make purpose of the present invention clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, is not intended to limit the present invention.
As shown in Figure 1, show that at solution display screen of the present invention display screen is the display screen of handheld device in the unusual method flow diagram, and the method is based on detecting decision circuitry, detect decision circuitry and comprise main control module and the display screen that is connected with main control module, the method may further comprise the steps:
A GPIO mouth that can be configured to middle fracture of S1, selection main control module is connected with the TE signal end of display screen;
S2, this main control module of initialization are configured to middle fracture with this GPIO mouth;
The TE signal end output TE signal of S3, this display screen sends the GPIO mouth of main control module to; Feedback signal during the normal operation of this TE signal (English is Tearing effect output signal) expression display screen is that frequency is the pulse signal of 60Hz, can test this signal with oscillograph;
S4, main control module are counted the pulse signal of this GPIO mouth;
S5, main control module in Preset Time with data and the pre-set threshold value of record relatively, if the data that record are less than pre-set threshold value then think that display screen is unusual, execution in step S6;
S6, display screen is carried out reset operation.
Further, step S5 is further comprising the steps of:
If the data of S51 record are more than or equal to pre-set threshold value then think that display screen without unusually, then returns step S4 and continues to detect.
Further, further comprising the steps of behind the step S6:
S7, return step S4 and continue to detect.
Further, main control module can arrange data and the Preset Time of pre-set threshold value in relatively of record in Preset Time according to actual needs, usually can be set to 2 seconds by Preset Time.
Further, main control module is definite value with data and the pre-set threshold value of pre-set threshold value in relatively of record in Preset Time.The user can arrange this decision threshold as required, usually can this pre-set threshold value be set to 50.
In the specific works process, display screen is when normal operation, by the GPIO mouth of TE signal end output TE signal to main control module, this main control module is counted the pulse data of this GPIO mouth, and in Preset Time, data and the pre-set threshold value that records compared, if the data of record are less than pre-set threshold value then think that display screen is unusual, then this main control module carries out reset operation to display screen, if the data of record more than or equal to pre-set threshold value then think display screen normal operation, are proceeded to detect.Adopt the method can when display screen is subject to static or other interference and blank screen occurs, determine whether display screen is carried out the method for reset operation by the state of judging current display screen, having solved is interfered at display screen must pull out that battery re-powers or carry out the switchboard operation and could recover normally experiencing without the user of demonstration by the user after blank screen occurring, so that obtaining better user, the user experiences, and do not need in the method to judge by reading the relevant register value of display screen whether display screen is unusual, can reduce to take cpu resource.
As shown in Figure 2, show in the unusual system at solution display screen of the present invention, comprise main control module 10, and the display screen 20 that is connected with main control module 10; This main control module 10 is connected with the TE signal end of display screen by a GPIO mouth that can be configured to middle fracture, and the reset terminal of this main control module connects the reset terminal of display screen; The TE signal end output TE signal of display screen sends the GPIO mouth of main control module to, feedback signal during the normal operation of this TE signal (English is Tearing effect output signal) expression display screen, be that frequency is the pulse signal of 60Hz, can test this signal with oscillograph; Main control module is counted the pulse signal of this GPIO mouth, data and pre-set threshold value with record in Preset Time compare, if the data of record are less than pre-set threshold value then think that display screen is unusual, main control module carries out reset operation to this display screen, and namely the reset terminal of main control module sends steering order and to the reset terminal of display screen display screen carried out reset operation.
Further, main control module thinks then that more than or equal to pre-set threshold value display screen without unusually, continues display screen is detected in the data that detect record.
Further, main control module can arrange data and the Preset Time of pre-set threshold value in relatively of record in Preset Time according to actual needs, by being set to 2 seconds by Preset Time.
Further, main control module is definite value with data and the pre-set threshold value of pre-set threshold value in relatively of record in Preset Time.The user can arrange this decision threshold as required, usually can this pre-set threshold value be set to 50.Namely when main control module detects TE signal pulse quantity that display screen sends and is less than 50 in Preset Time, illustrate that then display screen is unusual, if more than or equal to 50, the display screen normal operation is described then.
In the specific works process, display screen is when normal operation, by the GPIO mouth of TE signal end output TE signal to main control module, this main control module is counted the pulse data of this GPIO mouth, and in Preset Time, data and the pre-set threshold value that records compared, if the data of record are less than pre-set threshold value then think that display screen is unusual, then this main control module carries out reset operation to display screen, if the data of record more than or equal to pre-set threshold value then think display screen normal operation, are proceeded to detect.Adopt the method can when display screen is subject to static or other interference and blank screen occurs, determine whether display screen is carried out the method for reset operation by the state of judging current display screen, having solved is interfered at display screen must pull out that battery re-powers or carry out the switchboard operation and could recover normally experiencing without the user of demonstration by the user after blank screen occurring, so that obtaining better user, the user experiences, and do not need in the method to judge by reading the relevant register value of display screen whether display screen is unusual, can reduce to take cpu resource.
The above only is preferred embodiment of the present invention, not in order to limiting the present invention, all any modifications of doing within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
