Specific embodiment
In being described below, for illustration and not for limitation, the tool of such as particular system structure, technology etc is proposed
Body details, to understand thoroughly the embodiment of the present invention.However, it will be clear to one skilled in the art that there is no these specific
The present invention also may be implemented in the other embodiments of details.In other situations, it omits to well-known system, device, electricity
The detailed description of road and method, in case unnecessary details interferes description of the invention.
In order to illustrate technical solutions according to the invention, the following is a description of specific embodiments.
As shown in Figure 1, for a kind of step flow chart for showing data flaw detection method provided in an embodiment of the present invention, packet
It includes:
Step S101 obtains the detection data carried from the display signal that signal source generator is transmitted to display screen module
Style, and whether detect the detection data style consistent with the reference data style that prestores.
Specifically, the display screen in the embodiment of the present application is primarily referred to as liquid crystal display, also may include OLED or other
It is suitble to the display screen of this detection pattern.
Step S102, if the detection data style and the reference data style are inconsistent, according to the defect prestored
Examination criteria determines the accumulation display defect that signal is shown in the display screen viewing area to be detected.
Specifically, reference data style successively judges each single item of detection data style, if there is a Xiang Butong,
Think that detection data style and reference data style are inconsistent.In a specific embodiment, when each data are sent out in transit
It when raw abnormal, such as is interfered, data can change, such as become 0 from 1 or become 1 from 0.When detection data style and reference
Data style has inconsistent situation more afterwards, notes down the situation, can also further note down the generation of inconsistent data unit
Number.
Step S103 carries out display defect alarm if the accumulation display defect is more than preset display defect threshold value.
After adopting the above scheme, directly the detection data style shown in signal and reference data style can be carried out pair
Than display defect detection being carried out without suspending the display of viewing area, if comparison obtains detection data style and reference data formula
Sample is inconsistent, and the signal helped to detect between signal source (driving side) and display module (recipient) is transmitted either with or without appearance
It is abnormal, determine the accumulation display defect in viewing area, and alarm is carried out according to the concrete condition of accumulation display defect and reminds work
There are problems for personnel viewing area, real-time detection can show data in the case where not stopping viewing area and showing, improve display number
According to stability and accuracy, facilitate the use of onboard system user.
In addition, in a specific embodiment, carrying the detection data style in the blank area of the display signal.
Specifically, as shown in Fig. 2, viewing area is used to show the related data of onboard system, positioned at display screen to be detected
Central area, blank area are used to detect viewing area when viewing area shows the related data of onboard system, show signal
Display data can be written from left to right line by line from top to bottom, blank area is to show to be left white the time other than signal time.Letter
Number source generator is exported by preset detection data style output sequence from the display signal blank area of display screen to be detected
A kind of detection data style, reference data style are stored in the sequence controller (Timing in display screen display module to be detected
Controller, TCON) in IC (integrated circuit, integrated circuit).Wherein, in a specific example, aobvious
Show the right of the viewing area of signal source and following detection data style be added, that is to say, that the method will test data style with
Display signal is sent out at time point for arranging properly, specifically by preset detection data be added in every row show after signal or
After each column show signal, with display signal as the time is sent out, then by display module contrasting detection data style and reference
Inspection according to style, thus primary data is that there are data are unstable or interference problem.This method requires signal source IC and display module
Sequence controller (Timing Controller, TCON) IC be fitted also with support data style detection function, it may also be said to
Signal source IC and TCON IC have the function of that the detection data pattern for distinguishing over display signal can be recognized.In this embodiment,
All detection data styles and reference data style can be preset in the TCON in display source signal IC and display module respectively
In IC, without especially signal source hardware resource upgrade, it is simple and easy to use.
It is that its height and width are all distinguished by the resolution setting of display source signal generator in another specific example
Higher than the height and width of the fixed resolution.
Above-mentioned two embodiment can be implemented in blank area, such as detection data formula is added with following on the right of viewing area
Sample, but in later embodiment, as shown in figure 3, the resolution ratio of display source signal IC setting calculates detection data style
It is interior, and the resolution ratio of TCON IC setting then remains unchanged.For example, the resolution ratio of script is 1280x720, display source signal is sent out
The resolution setting of raw device is 1284x722, and is fixed 1280x720 by the resolution setting of TCON IC, therefore TCON
IC can recognize 4 rows being on the right side of blank area outside viewing area when receiving from the signal of display source signal generator automatically
2 row horizontal pixel of vertical pixel and downside, it is only necessary to import automatic recognize in TCON IC and be located at blank area outside viewing area
Detection data style function, display source signal need to only cooperate TCON IC simply to set resolution ratio and change display driving software, inspection
Measured data style can increase or decrease according to actual needs, and flexibility is higher, and not need additionally to increase hardware configuration.
Difference is that the length of its valid data gating signal (DE) is different in above-mentioned two embodiment, and the DE is for distinguishing
Effectively display signal and other signals, corresponding data-signal can be considered as effectively showing letter during DE is in high potential
Number.In one embodiment, the length of DE signal is to set originally, i.e., the length is conveying effectively display signals to be taken
Between, so signal source needs the function of supporting detection data style.And in second method, resolution ratio is considering testing number
After style, DE signal is relatively extended.Horizontal DE and vertical DE is extended respectively corresponding to required for transmission detection data
Time.According to the method, also need that there is support and identification detection data formula in TCON IC and described one embodiment
The function of sample, and this function is not needed then in signal source, but only that being made in setting resolution ratio and display driving formula
Change, therefore data style can be modified to increase according to actual needs by formula and reduce or change, flexibility is higher.
After adopting the above scheme, the detection data style and ginseng that will directly can be exported in the display signal blank area of display screen
It examines data style to compare, carries out display defect detection without suspending the display of viewing area, if comparison obtains detection data
Style and reference data style are inconsistent, help to detect the letter between signal source (driving side) and display module (recipient)
Number transmission is abnormal either with or without occurring, and determines the accumulation display defect in viewing area, and according to the concrete condition of accumulation display defect
Carrying out alarm reminds driver/staff viewing area that there are problems, can examine in real time in the case where not stopping viewing area and showing
Display data are surveyed, the stability and accuracy of display data is improved, facilitates the use of onboard system user.
In addition, in a specific embodiment, the method also includes:
If the detection data style is consistent with the reference data style, acquisition is transmitted to aobvious from signal source generator
Another detection data style carried in the display signal of display screen mould group, using received detection data style as new detection
Data style re-executes the whether consistent step of reference data style stating detection data style described in the detection Yu prestoring
Suddenly.
Specifically, the viewing area for representing display screen to be detected is not deposited if detection data style is consistent with reference data style
In the corresponding failure of detection data style, then obtains and taken from the display signal that signal source generator is transmitted to display screen module
Another detection data style of band is held again then using the detection data style received as new detection data style
Whether detection data style is stated in row detection consistent with the reference data style that prestores, if unanimously, output is another again detects
Data style determines in the display screen viewing area to be detected according to the defects detection standard prestored if inconsistent and shows letter
Number accumulation display defect.Wherein, different detection data styles refers to is made of not the voltage for being applied to pieces of data line
Same pattern, detection data style can there are many, it is in a specific embodiment, including 12 kinds of detection data styles, specific to wrap
Having included can apply in RGB, openLDI (open LVDS display interface, LVDS (Low Voltage Differential
Signaling, Low Voltage Differential Signal)), eDP (embedded displayport, embedded display interface) and mini-
Detection data style in the display interface interface LVDS (miniature LVDS).
In addition, in a specific embodiment, being transmitted to the aobvious of display screen module in described obtain from signal source generator
Before showing another detection data style carried in signal, further includes:
Another detection data style of output is sent by prefixed time interval to instruct to the signal source generator.
Specifically, the digit position (R0-B7) for having received bout just has received a kind of data style for it.Accordingly, it
The interval time between every kind of detection data style is calculated, first has to look at whether the pixel of every a line shows that signal is all added
A kind of detection data style is just added in detection data style, or the certain number of line number in interval.If it is the latter, detection data
Style then be about two detection data styles between row shared by the time.It, can be by the component part of a frame if it is the former
Subdivision considers, as shown in Fig. 2, the time of a frame includes vertical timing: Vsync+VBP+VAdr+VFP, it is each in vertical timing
Row includes: again Hsync+HBP+Hadr+HFP.Wherein Hadr is timing and a line of the effective pixel data in start and ending
Middle valid pixel number, HBP (horizontal synchronization pulse starts timing, Horizontal back porch) indicate horizontal synchronization arteries and veins
It washes the Duan Shixu before starting that begins to the effective pixel data of a line open, also illustrates that the picture that effective pixel data is not shown before starting
Plain number, HFP (horizontal synchronization pulse terminates timing, Horizontal front porch) indicate the effective pixel data of a line
After start to next horizontal synchronizing pulse before timing, the number of pixels not shown after also illustrating that effective pixel data.
Detection data style is occupied to can be whole/part HBP or HFP time in fact, shows signal in the pixel of every a line
In the case where detection data style all is added, such as a kind of detection data style is fallen on the right side of blank area, and occupying is
(R0-B7), the interval of detection data style is exactly the remaining HFP of Hsyc+HBP+Hadr+ of a line.For example, at one point
Rate rate is in 1920X1200 custom liquid crystals display screen, and the frame per second of display is 60Hz, so needed for sending out a kind of detection data style
Time is about 1/60=16ms, Vsync=3, VBP=5, VFP=8 and Vadr=1200；Hsync=12, HBP=16, HFP=
26, Hadr=960, so every row takes 13.7 μ s.The detection data fallen on the right side of blank area accounts for 7 pixels of HFP, so often
In the case that all detection data style is added in row, the interval between data style is about 13.6 μ s twice.Detection data style institute
The time that can also be the Hadr in the VFP of whole/part occupied, e.g. one or more detection data styles fall in blank
On the downside of area, continuous detection data style can be added in the Hadr in VFP in the case of this, continuous detection data style of going together it
Between interval time can be considered 0, and the detection data style of the adjacent rows in VFP is then separated by the time of Hsyc+HBP+HFP.By
There is larger space on the downside of viewing area, can be used and repeat detection data style, make long period and careful detection.
In addition, in a specific embodiment, passing through the number between the signal source generator and the display screen module
The detection data style is conveyed according to line.
In addition, in a specific embodiment, the detection data style is is applied to the signal source generator and institute
State the combination of the voltage style of the data line between display screen module.
In addition, in a specific embodiment, the detection data style for being applied to data line is low level voltage data formula
The opposite data style of the detection data style voltage of sample, high-order voltage data style or adjacent data line.
Specifically, in addition, in a specific embodiment, R0, G0, B0 are blank areas after the effective display pixel of a line finishes
One of three detection data units of head in detection data, followed by data unit R1, G1, B1；R2,G2,
B2 ... Rn, Gn, Bn depend on the length of used detection data.Since the detection data style is by data line from signal
Source is transmitted to display screen module, and the distribution of data unit on the data line depends on used data line interface type, such as
Bis- 8 lines of above-mentioned OpenLDI VESA, so data style also reflects data line and transmits corresponding voltage when the detection data
Just.Fig. 4 shows multiple detection data styles as an example: detection data style 1: full low level (being indicated with full 0), i.e., with low
Position voltage is applied to all data lines；Detection data style 2: overall height position (indicates) with complete 1, i.e., is applied to high-order voltage all
Data line；Detection data style 3 and 4 is the example used in RGB display interface interface: RGB Alt.1 and RGB Alt.2,
Voltage between i.e. adjacent data line is opposite, that is to say, that the high-order voltage between data line replaces implementation with low level voltage；
Detection data style 5 to 8 is the detection data style applied by VESA format in LVDS display interface interface.Wherein, it is examining
In measured data style 5 and 6, the voltage of adjacent data line be it is identical, in detection data style 7 and 8, adjacent data line
Voltage is opposite, that is to say, that the high-order voltage between data line replaces implementation with low level voltage.Detection data style 9 to 12 is
The detection data style applied by JEIDA format in OpenLDI display interface interface.Wherein, in detection detection data style 9
Into 10, the voltage of adjacent data line is identical (identical is high/low position voltage), in detection detection data style 11 to 12
In, the voltage of adjacent data line is opposite, that is to say, that the high-order voltage between data line replaces implementation with low level voltage.
As shown in figure 5, the detection data style combination referred to the time for the embodiment of detection data style combination
And change/certain detection data style is kept, or specific a variety of detection data styles are used alternatingly.That is, with regard to this hair
For bright, data style is data unit (the high-order voltage/low level electricity statically listed in digit position (such as R0-B7)
Pressure), and the data unit that the combination of data style is dynamically listed in each digit position changes with time.And both with
The data line of transportation data is associated.Wherein, data style combination i indicates that all data lines are all kept whithin a period of time
Low level voltage, and data style combination ii indicates that all data lines all keep high-order voltage whithin a period of time.Data style
Iii and iv is combined, data style combines v and vi, and data style combination vii and viii is illustrated respectively in RGB, OpenLDI VESA
And the data line in the display interface interface of OpenLDI JEIDA replaces between high-order voltage and low level voltage at any time.Number
It is various data style combination according to style combination ix, such as voltage level can be kept for a period of time, and can be in another a period of time
Apply alternate high-order and low level voltage, helps and test out random disturbances, such as ESD, EMI.Preferably, this random test is suitable
The case where being added on the right side of blank area together in detection data style.It is helped using different data style combined test and tests out data line
Different abnormal problems, some abnormal conditions can not be detected in a kind of combination of data style but can be in another data types
It is found in sample combination.
In addition, in a specific embodiment, if the detection data style and the reference data style are different
It causes, further includes: record the number that the inconsistent detection data style and the reference data style occur.
In addition, in a specific embodiment, if the detection data style and the reference data style are different
It causes, further includes: record the digit position of error, the data style and data style placement location of mistake occurs, and be stored in and post
In reservoir.
Specifically, can record the digit position (R0-B7) of error, the data style that mistake occurs, data style places position
It sets, accumulate it and is stored in storage device, and further pass through related data judging questions and prospect.Digit position can correspond to
Data line (supply line), it is different according to different display interfaces, such as in bis- 8 lines of OpenLDI VESA, first group of data
Line transmits G0, R5, R4, R3, R2, R1, R0, and second group of data line transmits B1, B0, G5, G4, G3, G2, G1, third group data line
Transmit 0 (or DE), 0 (or Vsyc), 0 (or Hsyc), B5, B4, B3, B2, the 4th group of data line transmission 0, B7, B6, G7, G6, R7,
R6.Therefore, when knowing data exception by detection data style, corresponding data line can be found out and gone wrong, can push away
Calculating the display data that the data line is conveyed may also go wrong.
As it can be seen that the threshold value standard can only consider it is inconsistent whether there is or not occurring when being added a kind of detection data style every time
Situation, then calculate detected in a period of time how many data style occur it is inconsistent.Such as it is all showing in a frame
Detection data is added in the right side of every a line in area, if accumulating there are inconsistent detection data is more than 100 times in three seconds,
Then it is more than threshold value (three seconds 100 times record events).The threshold value standard is also conceivable to that number occurs in each detection data style
According to the inconsistent situation of unit, the total data unit hair in each data style being added in a period of time is then calculated
Raw inconsistent number.For example, same setting, calculating the accumulation in three seconds, whether there are inconsistent data units more than 700
It is secondary.
