First embodiment
In the mura compensation display methods that first embodiment of the invention is provided, display is needed to terminal device realizing Image to be displayed carry out mura compensation display before, it is necessary to prestore mura pixel compensation data in terminal device. When follow-up mura compensates the execution each time of display methods, the mura pixel compensations data prestored using this are completed pair Mura compensates the execution of display methods.It is understood that after mura pixel compensation data are prestored, in follow-up mura compensation During the execution each time of display methods, without prestoring mura pixel compensation data again.
Referring to Fig. 2, Fig. 2 shows that a kind of mura that first embodiment of the invention is provided compensates the method stream of display methods Journey.Mura compensation display methods shown in Fig. 2 is the method flow that mura pixel compensation data are prestored in terminal device, Specifically, mura compensation display methods includes:Step S100, step S200 and step S300.
Step S100:Obtain in each target gray scale value, the brightness of each pixel in the default display picture Data.
When terminal device is analyzed and processed to shown default display picture, the default display picture must be obtained first Face.In the present embodiment, can by high definition camera to the RGB component of the default display picture shown by terminal device not With target gray scale value when taken pictures, and the photo taken is sent to terminal device, existed so that terminal device is obtained Default display picture during each target gray scale value.Wherein, the default display picture can be pattern patterns, but not limit, It can voluntarily set default display picture according to the actual requirements.In addition, each target gray scale value is that can be used as multiple specific GTGs Value, for example:16th, 32,48,64,94 and 128 etc..
Terminal device is got after the default display picture in each target gray scale value, and terminal device is in each target gray scale Default display picture during value is parsed.Due to acquired in terminal device being same default display picture in different GTGs Under state, and then terminal device obtains each brightness number of the pixel in each target gray scale value in the default display picture According to for example, pixel (1.1) exists:Brightness data of the brightness data of 16 GTGs, the brightness data of 32 GTGs and 48 GTGs etc.. It is understood that brightness data of each pixel in each target gray scale value can be the bright of the red component of the pixel The brightness data of degrees of data, the brightness data of blue component or green component.
In addition, for ease of follow-up processing, terminal device in the default display picture is obtained each pixel each After brightness data during target gray scale value, brightness number of the terminal device to each pixel of acquisition in each target gray scale value Handled according to smooth, denoising scheduling algorithm is carried out, the interference signal in data to filter out acquisition.
Step S200:According to brightness data of each pixel in each target gray scale value, extract described The mura regions in default display picture in each target gray scale value.
Because mura regions are for the normal region of surrounding, the brightness in mura regions has certain mutation, but not Directly it can be handled by the way of Threshold segmentation, this is due to the display screen reason itself or high definition camera pair of terminal device Terminal device carries out the angle reason of seat in the plane during default display picture collection, causes the brightness model in mura regions and normal region Enclosing may have overlapping, therefore directly using rim detection or Threshold segmentation, often segmentation rate is higher by mistake, therefore needed before segmentation Background estimating is carried out to complicated varying background and background suppresses.
In the present embodiment, default display picture when terminal device is to each target gray scale value carries out background estimating, i.e., Brightness data of the terminal device according to each pixel in each target gray scale value, obtains the pixel in each target gray scale value When brightness data corresponding to object brightness data.The algorithm that terminal device obtains object brightness data can be according to actual conditions Selected, if for example, default display picture can select surface polynomial fitting algorithm for the luminance background of smooth variation.
Terminal device will be offseted in the background estimating and default display picture of each target gray scale value, you can be obtained each Background during target gray scale value suppresses, i.e., terminal device by brightness data of each pixel in each target gray scale value with it is right The object brightness data answered are offseted, to obtain brightness data of each pixel in each target gray scale value and corresponding target Difference data between brightness data.It is understood that when the difference data of pixel is within preset range, then the pixel In normal region, when the difference data of pixel is beyond preset range, then the pixel is in mura regions.If for example, Preset range is -2 to 2, and when target gray scale value is 32, the brightness data and object brightness data of pixel (1.1) are 30, then Difference data is 0, and then pixel (1.1) is located at normal region.In another example, if preset range is -2 to 2, target gray scale value is When 32, pixel (3.3) brightness data and object brightness data are respectively 30 and 33, then difference data is -3, and then pixel (3.3) it is located at mura regions.Judgement by background suppression and terminal device to difference data, terminal device is tentatively extracted The default mura region of the display picture in each target gray scale value.Mura regions now can be by the side of bianry image Formula is showed, i.e., mura regions be 1, normal region is 0, or vice versa it is as the same.
Further, since now there may also be the influence of noise etc., there are some isolated points in the mura regions extracted, and then It can be post-processed using mathematical Morphology Algorithm, to reduce isolated point so that the default display picture is in each target gray scale Mura regions during value are more accurate.
It should be noted that each object brightness data of the pixel in each target gray scale value can be pixel every During individual target gray scale value, the object brightness data of red component, the object brightness data of blue component or the target of green component Brightness data.
Step S300:According to the brightness data of each default mura pixels, generate and store the mura pixels Offset data, wherein, the default mura pixels are located at the mura areas corresponding at least one described target gray scale value In domain.
Target gray scale value in the present embodiment is multiple, and each target gray scale value corresponds to mura regions.Default mura pictures Element is to be located in the mura regions corresponding at least one target gray scale value.For example, target gray scale value is 16 mura regions There is pixel A, but pixel A in except target gray scale value for the mura regions of 16 other target gray scale values positions not Occur, but pixel A is still default mura pixels.
Terminal device obtains this pre- according to the brightness data in each target gray scale value of each default mura pixels If the preset gray scale data in each target gray scale value of mura pixels.Specifically, in terminal device to each default Mura pixels set up the coordinate system of the default mura pixels, the coordinate representation of x-axis each target gray scale value, the seat of y-axis Mark illustrates the default mura pixels brightness data corresponding in each GTG, to obtain the coordinate point of the pixel Cloth.For example, the coordinate distribution of the pixel can be:(16.17), (32.36), (48.45) and (64.64) etc..Terminal device The coordinate distribution of the default mura pixels of this in coordinate system is connected, then obtains each color component of the default mura pixels Brightness curve.Wherein, when the poor linearity of brightness curve, being fitted of brightness curve can also be handled.Now, terminal Equipment is by the brightness curve of each default mura pixels, searching the default mura pixels in each target gray scale value Object brightness data in numerical value of the brightness curve correspondence in x-axis, each numerical value is the default mura pixels right Preset gray scale data during the target gray scale value answered, and then each default mura pixels are obtained in each target gray scale Corresponding preset gray scale data during value.It should be noted that each preset gray scale data can be the pixel red component The preset gray scale data of preset gray scale data, the preset gray scale data of the pixel blue component or the pixel green component. Each target gray scale value can be target gray scale value, the target gray scale value of blue component or the target of green component of red component Grey decision-making.
Now, the preset gray scale data according to each default mura pixels in each target gray scale value, then generation should The preset gray scale offset data of default mura pixels.Specifically, terminal device obtain the numerical value of each preset gray scale data with Difference between the target gray scale value of matching, each difference is the offset of the default mura pixels..For example, default Preset gray scale data of the mura pixels A when target gray scale value is 16 are 17, and the difference then obtained is 1, and then this is default Mura pixels A is preset gray scale value 16 for 16 preset gray scale compensation subdata in target gray scale value, and offset is 1.It is logical The above method is crossed, terminal device obtains preset gray scale compensation of each default mura pixels in each target gray scale value Data, each preset gray scale of each default mura pixels compensates at least one interval value that subdata is constituted, and also constitutes The preset gray scale offset data of the default mura pixels.Also for example, default mura pixels A preset gray scale offset data Can be:Preset gray scale value 16, offset is 1;Preset gray scale value 32, offset is 0;Preset gray scale value 48, offset is 3; Preset gray scale value 64, offset is -1.Wherein, preset in mura pixels A preset gray scale offset data, at least one is interval Value is (16-32), (32-48) and (48-64).
Terminal device by the preset gray scale offset data Unified coding to each default mura pixels to nbit, and then Generate mura pixel compensation data, i.e. mura pixel compensations data and number is compensated by the preset gray scale of multiple default mura pixels Constituted according to Unified coding.Now, then by the data compression of mura pixel compensations it is stored in the storage element of terminal device.
It should be noted that each preset gray scale of the default mura pixels in each target gray scale value compensates subdata Can be the pre- of the preset gray scale compensation subdata, the preset gray scale of blue component compensation subdata and green component of red component If gray scale compensation subdata.
In the present embodiment, due to obtaining the pre- of each default mura pixels by the object brightness data of background estimating If gray scale compensation data, it is contemplated that the influence of background fluctuations, the gray scale compensation scope to mura regions can further reduce, The data package size of mura pixel compensation data also reduces accordingly.Further, since each being preset in mura pixel compensation data The preset gray scale compensation of mura pixels is difference data, thus it is big to effectively reduce the packet of mura pixel compensation data It is small, further reduce being taken up space in memory cell.
Referring to Fig. 3, Fig. 3 shows that a kind of mura that first embodiment of the invention is provided compensates the method stream of display methods Journey.Mura compensation display methods shown in Fig. 3 is that kind of a side for mura compensation displays is carried out to the image to be displayed in terminal device Method flow.Specifically, mura compensation display methods includes:Step S400, step S500 and step S600.
Step S400:Obtain the luma data of each pixel in image to be displayed.
Terminal device is before image to be displayed is shown on a display screen, and terminal device is firstly the need of acquisition figure to be shown The luma data of each pixel of picture.Specifically, terminal device is by parsing image to be displayed, wait to show to obtain this The luma data of each pixel in diagram picture.
Step S500:By the mura pixel compensation Data Matchings that the luma data of each pixel is equal and prestores, obtain The gray scale compensation data of each mura pixels in the image to be displayed are taken, wherein, the mura pixel compensations data are institute The preset gray scale offset data of each default mura pixels in the mura regions for the default display picture for stating terminal device.
Terminal device is got after the luma data of each pixel, and terminal device is just by the luma data of each pixel With the mura pixel compensation Data Matchings prestored.It is understood that the mura pixel compensation data prestored be before basis Preset the data that display picture is acquired and stores.Just the luma data of each pixel and is prestored when terminal device During mura pixel compensation Data Matchings, if the pixel does not exist and the pixel in the mura pixel compensation data prestored The default mura pixels matched somebody with somebody, then terminal device judge the pixel as the pixel normally shown.If the pixel is prestoring Mura pixel compensation data in exist and the pixel Point matching default mura pixels, then terminal device judge the pixel For mura pixels.And then terminal device is then corresponded to and obtained according to the preset gray scale offset data of the default mura pixels of matching Get the gray scale compensation data of the mura pixels.Therefore, by being matched to each pixel, terminal device is then obtained The gray scale compensation data of each mura pixels into image to be displayed.
Step S600:The ash of the mura pixels is updated according to the gray scale compensation data of each mura pixels Exponent number evidence, the image to be displayed is shown.
Terminal device in display when image is shown, it is necessary to will each normal pixel and it is each carry out mura compensation after Mura pixels shown.First, terminal device is in each normal pixel of display, and terminal device will each just Normal pixel, will each with the base of the luma data of the unmatched pixel of mura pixel compensation data as the pixel Quasi- data.Wherein, the luma data when reference data of each pixel is the display pixel.In addition, terminal device will also The gray scale compensation data of each mura pixels are superimposed with the luma data of the mura pixels, to update the mura pixels Luma data, and then realize the gray scale compensation to each mura pixels.Terminal device is in the GTG to each mura pixels After compensation, using each mura pixels update after luma data as the mura pixels reference data.
It should be noted that the luma data of each pixel can for the red component of the pixel luma data, The luma data of blue component or the luma data of green component.To the gray scale compensation of each mura pixels, being will be with this The red component preset gray scale compensation subdata of the default mura pixels of mura pixel Point matchings is added to the mura pixels The red component luma data on, the blue component gray scale compensation subdata and green component GTG of the mura pixels are mended Repay subdata also similarly, be just not repeated.
When terminal device encourages luma data after each mura pixels update as the reference data of the mura pixels Afterwards, terminal device will can be treated according to the reference data of each mura pixels and the reference data of each pixel, and then just Display image is accurately shown.
