Mouth region 22 may insure the presence for no matter being bonded tolerance or ink printing tolerance in this way, and the theoretical viewing area of the application can
Open region 22 is covered, that is, no matter is bonded tolerance and ink printing tolerance are how many, in the Region Theory in open region 22 all
It can be shown.So the influence of fitting tolerance and ink printing tolerance for display panel is avoided.Another party
Face, open region 22 cover actual displayed area BB, and by above-mentioned driving method, the position of actual displayed area BB is to pass through test
What image determined, so actual displayed area BB can guarantee not to be blocked, and can be said according to test image practical aobvious
Show that the centre of open region 22 is arranged in the position in area, it is sufficient to guarantee the consistency of production.
The driving method of the application display panel is illustrated by step below:
S1: it provides in test image 300 to the theoretical viewing area AA of display panel；Fig. 2 and Fig. 4 are please referred to, Fig. 4 is this Shen
Please another embodiment displaying panel driving method schematic diagram；
It provides and is specifically included in test image 300 to the theoretical viewing area AA of display panel:
S11: the image information of the test image is determined；The theoretical viewing area that test image 300 arrives display panel is provided
The purpose of AA is the position for wanting to determine open region 22.Firstly the need of can make that CCD camera is allowed to detect and calculate using one
Picture be transferred to theoretical viewing area AA.CCD camera can capture the luminance information of pixel scale, accordingly, it is determined that the survey
Attempt picture image information include: the test image 300 include one detection column, the detection column pixel show the first brightness,
Other pixels in the test image 300 show that the second brightness, first brightness are different from second brightness.Detection column
It is arranged in the theoretical viewing area for xth；It is equivalent in the present embodiment using theoretical viewing area AA as referential, in input test
It is 301 that we, which design first of test image, when image, and tail is classified as 302, and detection is classified as 305, wherein detection is classified as this
Xth column in referential.And the brightness of column and the difference of other column are detected, therefore detection can be captured by CCD camera and be listed in
Relativeness in test image determines the information of open region.
Further, in order to reduce calculation amount, the difficulty of detection is reduced, error is reduced
If the columns of the theory viewing area is odd number, it is centre one that the detection, which is listed in the theoretical viewing area,
Column；
If the columns of the theory viewing area is even number, it is that centre two arranges that the detection, which is listed in the theoretical viewing area,
In any one column.
Such as: the resolution ratio of theoretical viewing area AA is the display panel of 1920*1200, is arranged using rendered pixel, is wrapped
1200*2 column are included, can be by the 1200th column or the 1201st column as detection column, detection column in this way are generally within display panel
Middle position, when CCD camera face detects column shooting picture, to test image 300 first 301 and tail column 309
Distance it is similar, the distortion of camera lens is also similar, can reduce error, reduces the workload of distortion correction.
For another example: the resolution ratio of theoretical viewing area AA is the display panel of 1920*1199, is arranged using rendered pixel,
It is arranged including 1199*3, it can be by the 1799th column as detection column, likewise, centre of the detection column generally within display panel in this way
Position, CCD camera face detect column shooting picture when, to test image 300 first 301 and tail column 309 away from
Deviation is few, and the distortion of camera lens is also similar, can reduce error, reduces the workload of distortion correction.
S12: determine the test image in the position of the theoretical viewing area；Determine the test image in the theory
The position of viewing area specifically includes: the edge of test image 300 is shown at the edge of the open region and the theoretical viewing area
Between the edge in area.Namely test image 300 first 301 and tail column 309 must exceed open region 22, but fall in theory
Viewing area first 101 and tail column 109 between can guarantee in this way show information do not spill over, data are accurate.And test image
300 first 301 and tail column 309 it is big in the area ratio open region 22 for also just representing test image 300 beyond open region 22, opening
Luminance information is centainly had in area, just can ensure that the position of open region 22 can be accurately determined in this way.
In order to guarantee that the edge of test image 300 has two between the edge of open region 22 and the edge of theory viewing area AA
Kind method.
The first:
The resolution ratio of test image 300 is arranged to consistent with the theoretical resolution ratio of viewing area AA.Test image first
301 for theoretical viewing area first 101, the tail column 309 of test image are the tail column 109 of theoretical viewing area, be may insure in this way
Test image 300 is beyond open region 22 but without departing from theoretical viewing area AA.
Second:
Estimate the open region 22 in the position of the theoretical viewing area；
It specifically includes:
First for determining the design position of the open region 22 arranges in the theory viewing area AA for a, and tail is listed in institute
It states in theoretical viewing area AA and is arranged for b；
Determine fitting tolerance p column；
Determine ink printing tolerance q column；
First of the test image is located at before the a-p-q column of the theory viewing area AA, the test image
Tail column are after the b+p+q column of the theory viewing area AA.
Above calculation method calculates the extreme value that design position is deviateed in open region 22, when fitting tolerance and ink printing are public
When difference deviates to the same direction, open region 22 first be a-p-q, as long as therefore make test image 300 first
When 301 the 1st column in theoretical viewing area are between a-p-q column, then test image 300 is bound to exceed the left side of open region 22
Edge.Likewise, the tail of open region 22 is b+p+q when being bonded tolerance and ink printing tolerance deviates to the same direction,
As long as therefore make test image 300 first 301 when the b+p+q of theoretical viewing area is arranged between tail column 309, test
Image 300 is bound to exceed the right hand edge of open region 22.When the edge of test image 300 namely first 301 and tail column 309 it is same
When meeting condition above, ensure that all have test image 300 in open region 22, it is ensured that CCD camera can be accurate
Detect the position in theoretical viewing area AA of open region 22.
S13: the test image is transferred to the theoretical viewing area；It is being determined that test image 300 needs to show
Specific image and display image the specific location in theoretical viewing area AA after, so that it may test image 300 is transferred to
It is tested in theoretical viewing area AA.
Further,
S2: determine actual displayed area BB first 401 and tail column 409；Fig. 1, Fig. 2, Fig. 5 and Fig. 6 are please referred to, Fig. 5 is this
Apply for the displaying panel driving method schematic diagram of another embodiment；Fig. 6 is that the display panel of another embodiment of the application drives
Dynamic method schematic diagram；
Determine that first and the tail column in actual displayed area specifically include:
S21: position of the open region in the theoretical viewing area is determined；It can be determined open according to the test image of S1
Position of the mouth region 22 in theoretical viewing area AA；
It specifically includes:
With CCD camera acquire optical data, mark the light emitting region first to it is described detection column distance be b1 arrange,
It is b2 column that the tail of the light emitting region, which is arranged to the distance of the detection column,；The light emitting region is the open region, needs to illustrate
The detection image 300 provided according to front S1, detection image 300 exceeds open region 22, due to being provided with oil outside open region 22
Ink assembly 21, ink assembly 21 can block the detection image 300 outside open region 22, therefore CCD camera acquired image
Information is image in open region 22.Also, CCD camera is able to detect the brightness data of pixel scale, is collected according to CCD camera
Optical data can determine detection column 305 (detection column luminance information and other arrange Bu Tong therefore can identify) extremely opening
(because being located at the edge of open region, there is luminance information in one side to first and the tail column in area 22, and side does not have brightness for first and tail column
Information by CCD camera so can be detected) distance.This distance can be calculated divided by the width of each column pixel and be fallen out
Number b1 and b2.
Since detection column 305 in the position of theoretical viewing area AA are setting value x, it can be with according to the detected value of front
First of setting open region 22 arranges in the theoretical viewing area for x-b1, and the tail of the open region is listed in the theoretical viewing area
In for x+b2 arrange；
S22: the actual displayed is determined according to position of the multiple open regions of measurement in the theoretical viewing area
The columns in area；Since the ink assembly of each display panel there can be printing tolerance when printing, and print tolerance all
Not identical, this results in the size of the open region 22 of each display panel to be actually different.Therefore, it is necessary to according to multiple aobvious
Show that the open region 22 of panel determines the columns of actual displayed area BB in the position of theoretical viewing area AA.If shown using single
Show panel to determine that the open area that may cause other panels is fewer than the columns for the actual displayed area BB that we set, thus
Can be blocked by ink assembly 21, the display panel for causing same batch or different batches to produce it is not of uniform size.This implementation
The mode of example avoids the generation of above situation by the principle of statistics and probability theory.It is further ensured that and produces display surface
The consistency of plate.
Specifically, the columns in design phase design actual displayed area is s column；
When the columns b1+b2 of the multiple open region 22 of measurement is all larger than or is equal to s, the actual displayed is determined
The columns t in area is s；The columns of the open region 22 of namely all display panels may insure often when being both greater than design value s
A open region 22 is both greater than design value, and the driving method using the application is then centainly not in hair the case where being blocked by ink
It is raw.Therefore, the columns t in actual displayed area can be determined as design value s.
When there is any one to be less than s column in the columns b1+b2 of the multiple open region 22 of measurement, the reality is determined
The columns t of viewing area is the minimum value in the columns b1+b2 of all open regions；The namely opening of at least one display panel
The columns in area 22 is less than design value s.If it is determined that the columns of actual displayed area BB is the reality of the design value s then display panel
Viewing area can then be blocked by ink.It is happened in order to avoid such, the columns t of actual displayed area BB is determined as these and is opened
The minimum value of 22 columns of mouth region ensures that the actual displayed area of each display panel does not have in this way and is blocked by ink assembly 21
It happens.
Further, to make the position in actual displayed area be that vision is placed in the middle in each display panel,
S23: adjusting position of the actual displayed area in the open region, so that the actual displayed area is positioned at described
The centre of open region.
It specifically includes:
First position in the theoretical viewing area for determining the actual displayed area is xth-b1+ (b1+b2-t)/2
Column；
The position for determining that the tail in the actual displayed area is listed in the theoretical viewing area is xth+b2- (b1+b2-t)/2
Column.
The principle designed in this way is, is t according to the columns in the test actual displayed area of front, and the columns of open region 22 is
B1+b2 then has the column of b1+b2-t without being shown, is exactly " black surround " that we are commonly called as, in order to guarantee actual displayed area
Vision it is placed in the middle, then the left and right side in actual displayed area should respectively have the black surround (b1+b2-t)/2 of half；The head of open region 22
Xth-b1 column are classified as, therefore first of actual displayed area should be x-b1+ (b1+b2-t)/2；The tail of open area be classified as xth+
B2 column, then the tail column of actual displayed area BB should be x+b2- (b1+b2-t)/2.It can guarantee actual displayed area BB distance in this way
The edge of open region 22 is the placed in the middle of equal realization vision.
Further, it is determined that first of actual displayed area needs for these information to be written to driving core later with tail column
Piece, and adjust the display information of driving chip.
S3: the display information in adjustment driving chip；
Specifically:
By first information x-b1+ (b1+b2-t)/2 and tail column information x+b2- (b1+b2-t)/2 in the actual displayed area
In storage area register；
Driving chip reads first described information and the tail column information, redefines data line columns.Write-in letter in this way
The data line of only actual displayed area BB can receive data line signal realization display after breath, and the stabilization for realizing display panel is aobvious
Show.And accomplish narrow frame as far as possible in the case where capable of meeting the requirements of the customers.
Further,
The driving chip reads first described information and the tail column information, redefines data line columns and specifically wraps
It includes: setting high-impedance state for the data line being located at other than first and tail column in the theoretical viewing area.
S4: data adjusted are transferred to the display panel.It finally will be into chip tune of overdriving in actual displayed
Data after whole are transferred to display panel and are shown.It will show that image has been adapted to the resolution ratio in actual displayed area in advance, realize
The display of complete information.And the technical effect of narrow frame is reached.
It should be noted that the described column of the application are opposite positional relationship, column described in the application are also possible to go,
Upper and lower or left and right described in the application.The application can be or adopting said method or row and column on pixel column
All narrow frames on four sides of adopting said method realization.
The driving method of the display panel of the application determines actual displayed area by providing test image to theoretical viewing area
Position, and write information into driving chip, display image is transferred to display panel, the application after driving chip processing
