Embodiment
In order to make object of the present invention clearly understand, 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, be not intended to limit the present invention.
As shown in Figure 1, in the method flow diagram that solution display screen display of the present invention is abnormal, display screen is the display screen of handheld device, and the method is based on detection decision circuitry, detect the display screen that decision circuitry comprises main control module and is connected with main control module, the method comprises the following steps:
The TE signal end of a GPIO mouth and display screen that can be configured to middle fracture of S1, selection main control module is connected;
S2, this main control module of initialization, be configured to middle fracture by this GPIO mouth;
The TE signal end of S3, this display screen exports the GPIO mouth that TE signal sends main control module to; This TE signal (English for Tearing effect output signal) represents feedback signal when display screen normally works, and the pulse signal of to be frequency be 60Hz, can test this signal with oscillograph;
S4, the main control module pulse signal to this GPIO mouth counts;
The data of record compare with pre-set threshold value by S5, main control module in Preset Time, if the data of record are less than pre-set threshold value, think that display screen is abnormal, perform step S6;
S6, reset operation is carried out to display screen.
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, think that display screen is without exception, then return step S4 and continue to detect.
Further, further comprising the steps of after step S6:
S7, return step S4 continue detect.
Further, the Preset Time during the data of record compare with pre-set threshold value by main control module in Preset Time can be arranged according to actual needs, usually Preset Time can be set to 2 seconds.
Further, main control module in Preset Time, the data of record are compared with pre-set threshold value in pre-set threshold value be definite value.User can arrange this decision threshold as required, usually this pre-set threshold value can be set to 50.
In specific works process, display screen is when normally working, TE signal is exported to the GPIO mouth of main control module by TE signal end, the pulse data of this main control module to this GPIO mouth counts, and in Preset Time, the data of record are compared with pre-set threshold value, if the data of record are less than pre-set threshold value, think that display screen is abnormal, then this main control module carries out reset operation to display screen, if the data of record are more than or equal to pre-set threshold value, think that display screen normally works, proceed to detect.Adopt the method can when display screen is subject to electrostatic or other interference occur blank screen by judging that the state of current display screen determines whether to carry out display screen the method for reset operation, solve display screen be interfered there is blank screen after must by user pull out battery re-power or carry out that switchboard operation could recover normally to show without Consumer's Experience, user is made to obtain better Consumer's Experience, and do not need in the method to judge that whether display screen abnormal by reading the relevant register value of display screen, can reduce and take cpu resource.
As shown in Figure 2, in the system that solution display screen display of the present invention is abnormal, comprise main control module 10, and the display screen 20 be connected with main control module 10; This main control module 10 is connected by the TE signal end of a GPIO mouth and display screen 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 of display screen exports the GPIO mouth that TE signal sends main control module to, this TE signal (English is Tearing effect output signal) represents feedback signal when display screen normally works, the pulse signal of to be frequency be 60Hz, can test this signal with oscillograph; The pulse signal of main control module to this GPIO mouth counts, in Preset Time, the data of record are compared with pre-set threshold value, if the data of record are less than pre-set threshold value, think that display screen is abnormal, main control module carries out reset operation to this display screen, and namely the reset terminal of main control module sends steering order and carries out reset operation to the reset terminal of display screen to display screen.
Further, main control module, detecting that the data of record are more than or equal to pre-set threshold value and then think that display screen is without exception, continues to detect display screen.
Further, the Preset Time during the data of record compare with pre-set threshold value by main control module in Preset Time can be arranged according to actual needs, by Preset Time being set to 2 seconds.
Further, main control module in Preset Time, the data of record are compared with pre-set threshold value in pre-set threshold value be definite value.User can arrange this decision threshold as required, usually this pre-set threshold value can be set to 50.Namely when main control module detects that the TE signal pulse quantity that display screen sends in Preset Time is less than 50, then illustrate that display screen is abnormal, if be more than or equal to 50, then illustrate that display screen normally works.
In specific works process, display screen is when normally working, TE signal is exported to the GPIO mouth of main control module by TE signal end, the pulse data of this main control module to this GPIO mouth counts, and in Preset Time, the data of record are compared with pre-set threshold value, if the data of record are less than pre-set threshold value, think that display screen is abnormal, then this main control module carries out reset operation to display screen, if the data of record are more than or equal to pre-set threshold value, think that display screen normally works, proceed to detect.Adopt the method can when display screen is subject to electrostatic or other interference occur blank screen by judging that the state of current display screen determines whether to carry out display screen the method for reset operation, solve display screen be interfered there is blank screen after must by user pull out battery re-power or carry out that switchboard operation could recover normally to show without Consumer's Experience, user is made to obtain better Consumer's Experience, and do not need in the method to judge that whether display screen abnormal by reading the relevant register value of display screen, can reduce and take cpu resource.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
