Specific implementation mode
In order to solve it is existing in the prior art can not weaken/or reduce laser repairing after dim spot display defect skill
Art problem, the embodiment of the present invention propose a kind of method and device of adjustment OLED display pixel, below by attached drawing and
Specific embodiment is described in detail technical solution of the present invention, it should be understood that the specific spy in the embodiment of the present invention and embodiment
Sign is the detailed description to technical solution of the present invention, rather than to the restriction of technical solution of the present invention, the case where not conflicting
Under, the technical characteristic in the embodiment of the present invention and embodiment can be combined with each other.
Embodiment one：
In the embodiment of the present application, it is proposed that a method of adjustment OLED display pixel.
Fig. 1 is please referred to below, and specific implementation process is as follows：
S101 detects the current value of each pixel of OLED display.
S102 determines the display location of the dim spot pixel in OLED display according to the current value detected.
S103 concentrates the related pixel pattern for determining dim spot pixel from pattern of pixels.
Wherein, pattern of pixels concentrates the display location of each pattern of pixels, between the display location of dim spot pixel
Distance meets preset distance.
S104 will constitute the display gray scale tune of at least one of the OLED display of related pixel pattern related pixel
Height, to compensate the gray scale of dim spot pixel.
Specific implementation process is described below.
Method in the embodiment of the present invention is suitable for OLED display.Although OLED display has done laser repairing,
In OLED display or many idle stains or dim spot can be left, therefore, after OLED display carries out laser repairing,
Detect the current value of each pixel of OLED display.
Because in the full frame work of OLED display, display brightness is more uniform, passes through each pixel in OLED display
Electric current all relatively.As a result, can by " in detection OLED display the current value of each pixel whether occur compared with
Big variation " comes whether the detection pixel pixel has defect.
And the defect of OLED display mainly has two aspects, i.e. fleck defect and DSD dark spot defect.Fleck defect is by OLED
In display there are bright spot pixel caused by, if in addition there is continuous multiple bright spot pixels, bright line can be constituted；DSD dark spot defect be by
In OLED display there are dim spot pixel caused by, if there is continuous multiple dim spot pixels, concealed wire can be constituted.
On the other hand, due in OLED display each pixel by red sub-pixel, blue subpixels, green sub-pixels three
Person is constituted；Or it is made of red sub-pixel, blue subpixels, green sub-pixels, white sub-pixels.Therefore, bright spot lacks
It falls into or DSD dark spot defect is essentially behave as：Constitute the sub-pixel defect of bright spot pixel or the sub-pixel defect of dim spot pixel.With
For DSD dark spot defect, if the red sub-pixel in some pixel of composition OLED display is damaged, then this pixel would not
There is red sub-pixel to shine, the brightness of pixel and coloration will be partially dark, and cause current anomaly, become dim spot pixel.If
White sub-pixels do not work, and situation becomes apparent.If by taking fleck defect as an example, if in some pixel of composition OLED display
White sub-pixels light emission luminance is excessively high, then the display brightness of the pixel can be significantly hotter than the pixel of surrounding, becomes bright spot pixel.
Certainly, bright spot pixel can be changed into dim spot pixel, and dim spot pixel can mainly obtain in terms of two, when by
Bright spot pixel transition forms.Second is that being obtained by detecting.
Before executing S102 steps, it can first detect and obtain bright spot pixel, process is as follows：
First, by the current value detected, the bright spot pixel of OLED display is obtained.
Then, control bright spot pixel is stopped, to be changed into dim spot pixel.
In electric current of the detection by each pixel, implement particular by periodic operation monitoring programme.Specifically,
This monitoring programme is integrated with hardware and software.It is made into an automatic control module, is placed on TCON or complete machine mainboard
With the mode of time triggered（Periodic operation, such as half a year are a cycle etc.）Call operation.
And since the electric current of each pixel is closer to, there are one indicate the normal current threshold model of current value for meeting
It encloses, such as 3mA ~ 5mA（It is only limitted to illustrate, similarly hereinafter）If the electric current for passing through some pixel is more than the range, then indicating the picture
It is known as defect.
Further, judge that the step of picture element flaw is bright spot pixel is then as follows：
It will be periodically compared by the current value of each pixel and predetermined current threshold range in OLED display.If having
When current value is higher than the peak of current threshold range, it is determined that the corresponding pixel of current value higher than peak is bright spot picture
Element.
Assuming that current threshold ranging from 3mA ~ 5mA, then can will then pass through the current value of each pixel of OLED display
It is compared with it, if there is the current value of some pixel to be higher than 5mA, illustrates pixel light emission exception, and can determine the picture
Element is bright spot pixel.
Further, due to being that the mode of " point by point scanning " is used to carry out in each pixel in detecting OLED display
Scanning, i.e., mode from top to bottom, from left to right scan, and therefore, if some pixel is abnormal, can further know that this is different
The position of normal pixel.
And detect certain pixel for after bright spot pixel, can control bright spot pixel is stopped, it is made to be changed into dim spot
Pixel.
In addition, the detailed process for detecting dim spot pixel in S102 is as follows：
It will be periodically compared by the current value of each pixel and predetermined current threshold range in OLED display.If
When thering is the current value of pixel to be less than the minimum of current threshold range in OLED display, then the current value pair of minimum is will be less than
The pixel answered is determined as dim spot pixel.Then the position of dim spot pixel is recorded.
Assuming that current threshold ranging from 3mA ~ 5mA, then if it is detected that the current value for carrying out some pixel is less than 3mA, then
It can then determine that the pixel is dim spot pixel.Detect dim spot pixel display location with it is above-mentioned similar, details are not described herein.
Certainly, other than current threshold range, the current value that some is determined can also be used as normal value, go forward side by side one
Step judges bright spot pixel and dim spot pixel using the normal value.Under request in person referring specifically to Fig. 2.
Fig. 2 is the curent change schematic diagram of OLED display bright spot and DSD dark spot defect.
Wherein, A indicates normal current value.If there is current value to be higher than normal value, then its corresponding pixel is bright spot picture
Element.If there is current value to be less than normal value, then its corresponding pixel is dim spot pixel.
After determining the position of dim spot pixel, then the step in S103 can be executed.
In the specific implementation process of S103, pattern of pixels, which is concentrated, to be had in a variety of pattern of pixels, such as Fig. 3 A- Fig. 3 F
Several pattern of pixels.
By taking Fig. 3 A as an example, black region is dim spot pixel in figure；The pattern that white area is constituted is one kind of pattern of pixels；
And gray area is normal pixel.
And the display location of each of which pattern of pixels and the distance between the display location of dim spot pixel meet it is predetermined
Distance, preset distance specifically please refer to Fig. 4.
Stain in Fig. 4 is dim spot pixel, it is assumed that and preset distance is the distance apart from two pixels of dim spot pixel,
The distance of virtual row frame in so Fig. 4 is then preset distance, the pixel within the preset distance（I.e. in white portion
Pixel）The pattern of composition all can serve as related pixel pattern.
Further, how to determine related pixel pattern, then there is following mode：
First, the priority orders of pattern of pixels are concentrated according to pattern of pixels, determine the pattern of pixels of highest priority
As related pixel pattern.
In specific implementation process, the pattern of pixels that pattern of pixels is concentrated has priority orders, such as Fig. 3 A-
Pattern of pixels in Fig. 3 F is numbered according to the sequence of priority.That is the highest priority of Fig. 3 A, the priority of Fig. 3 F is most
It is low.
It is determined at this time according to priority orders, then Fig. 3 A can be determined as to related pixel pattern.
Second, the pattern of pixels that control pattern of pixels is concentrated is in a manner of poll, according to prefixed time interval successively conduct
Related pixel pattern.
In specific implementation process, prefixed time interval is assumed to be 5 seconds, then being concentrated in pattern pixel, with poll
Mode, every five seconds for example can determine whether out a pattern of pixels as related pixel pattern.
During determination, a related pixel pattern can be determined according to the priority of pattern of pixels, every five seconds for example.
Can also every five seconds for example from pattern of pixels concentrate at random determine a pattern of pixels as related pixel pattern.
Such way then can be to avoid some related pixel pattern of adjustment during lightening related pixel pattern
The problem of leading to pixel ageing, damage, the service life of OLED display can be extended.
Further, after determining related pixel pattern, then the step in S104 can be executed.
It in specific implementation process, is illustrated with the related pixel pattern in Fig. 3 A, during adjusting gray scale, can be referred to
The display gray scale of pixel script in related pixel pattern, by the display gray scale tune of at least one of related pixel pattern pixel
It is high.
Such as in Fig. 3 A, related pixel pattern includes two pixels, and tonal gradation is all 128 when normally showing, that
When adjustment shows gray scale, the display gray scale of one of pixel can be adjusted to 144；Or the display ash of two pixels
It spends while being adjusted to 144.
In general, the pixel in display gray scale and related pixel pattern when dim spot pixel works normally originally is being adjusted
Display gray scale before whole is similar.The display gray scale for adjusting pixel in related pixel pattern at this time, can be based on " dim spot picture
Plain display gray scale when working normally originally " is adjusted, and can also be based on that " pixel in related pixel pattern is in adjustment
Preceding display gray scale " is adjusted.
Certainly, in a practical situation, the pixel in display gray scale and related pixel pattern when dim spot pixel works normally
Display gray scale before adjustment can also have larger difference.The display gray scale of pixel in related pixel pattern is adjusted at this time,
It can be adjusted based on " the display gray scale of pixel before adjustment in related pixel pattern ".
Specifically, when setting shows gray scale, adjusted according to display level, the pixel value difference of a grade is
16。
It should be noted that being adjusted to preferred embodiment according to difference 16, the present invention can also set other
Value.
In general, the display gray scale of at least one related pixel of related pixel pattern, the ash shown than normal pixel
At least high one of degree arrives three grades.
Further, the tonal gradation of each pixel adjustment in related pixel pattern can differ, that is, the picture set
The display gray scale of plain compensation point can be different.Such as the display gray scale of a pixel in Fig. 3 A could be provided as 144,
The display gray scale of one other pixel could be provided as 160.
More specifically, since in OLED display, each pixel can be by red, blue and green three sub-pixels
It constitutes；Or four red, blue, green and white sub-pixels are constituted.It, can be with so when the pixel to surrounding is adjusted
Defect based on sub-pixel is targetedly adjusted.
It is configured to example with red, blue, green and white four sub-pixels.
If the red sub-pixel display in certain pixel is abnormal, and then causes the pixel to be dim spot pixel, then in adjustment phase
During closing pattern of pixels, then the red sub-pixel in related pixel pattern at least one pixel can be adjusted, is shown
Gray scale is turned up.
And if the white sub-pixels display in certain pixel it is abnormal when, can be with other than adjustment mode like above
According to the display characteristic of true color mode, when white sub-pixels show exception, white sub-pixels do not work, it is turned up at this time
The display gray scale of his three sub-pixels is compensated in a manner of simulating white sub-pixels and shining.
Specifically, true color mode is OLED colorization modes, specifically includes RGB（Red, green, blue）Three colors
Light emitting structure and colour change structure（White light+colored filter）.
In above-mentioned implementation process, in the presence of having dim spot pixel, just determined and dim spot pixel from pattern of pixels concentration
Then relevant related pixel pattern will constitute the aobvious of at least one of the OLED display of related pixel pattern related pixel
Show that gray scale is turned up.The advantage of doing so is that grey level compensation can be done using related pixel pattern, with decrease/or dim spot picture is reduced
The harmful effect that element is brought in itself.
In addition, the above method is also applied for bright line（Multiple continuous bright spot pixel compositions）And concealed wire（By multiple continuous dim spots
Pixel forms）, by the pixel compensation point for setting higher gray scale up and down in concealed wire（Display is adjusted i.e. in related pixel pattern
The pixel of gray scale）, the harmful effect of concealed wire can be mitigated.
Further, in the display ash that will constitute at least one of the OLED display of related pixel pattern related pixel
After degree is turned up, also there is following step：To constitute at least one of OLED display of related pixel pattern related like
The driving frequency of element is turned up.
If OLED display some pixel when showing tableaux has DSD dark spot defect, when by its is corresponding " related like
At least one of the OLED display of sketch map case related pixel "（That is pixel compensation point）Display gray scale be turned up after, may be used also
To increase the driving frequency of pixel compensation point so that the display number of pixel compensation point at the same time increases, for compensating
Dim spot pixel makes the viewing effect of user more preferably to the collimation error caused by user.
If OLED display some pixel when showing dynamic menu has DSD dark spot defect, pixel compensation point can be set
Driving frequency increases at multiple, i.e. the driving frequency of pixel compensation point is the multiple of DSD dark spot defect driving frequency, to compensate dim spot
Pixel makes the viewing effect of user more preferably to the collimation error caused by user.
