Specific embodiment
In order to make the foregoing objectives, features and advantages of the present invention clearer and more comprehensible, with reference to the accompanying drawing to the present invention
Specific embodiment be described in detail.Many details are explained in the following description in order to fully understand this hair
It is bright.But the invention can be embodied in many other ways as described herein, those skilled in the art can be not
Similar improvement is done in the case where violating intension of the present invention, therefore the present invention is not limited by the specific embodiments disclosed below.
Illustrate the acquisition process of Mura offset data below in conjunction with Fig. 1 a.The system includes image collecting device 120, number
According to processing unit 130.Image collecting device 120 can be CCD camera.Wherein, data processing equipment 120 and image collecting device
Connection is established between 130.Image Acquisition is carried out simultaneously to the detection picture that display panel 110 is shown by image collecting device 120
It goes to extract corresponding brightness data, then, the brightness data of searching picture is sent to data processing by image collecting device 120
Device 130 is handled by brightness data of the data processing equipment 130 to the detection picture that display panel 110 is shown to obtain
To the corresponding offset data of detection picture.Obtained offset data is burned onto the flash memory of display panel 140 to be compensated
In.
In one embodiment, b referring to Figure 1, the application provides a kind of method for obtaining Mura offset data, with the party
Method is applied to be illustrated for the data processing equipment 130 in Fig. 1 a, and this approach includes the following steps：
S110, under preset gray scale, obtain display panel shown by detect picture brightness data, detection picture include
Secondary colour grey menu.
Wherein, display panel can be but not limited to Plasmia indicating panel, liquid crystal display panel (LCD), light-emitting diodes
Pipe display panel (LED) or organic LED display panel (OLED) are provided with the pixel of array arrangement on display panel,
One pixel is made of red R, green G, blue tri- sub-pixels of B.The light source of each sub-pixel can be shown not
Same gray scale, can be indicated with grayscale.Grayscale is represented by most secretly to the stratum level of different brightness most bright.Display
What the display data that each pixel is all based on RGB three primary colours in panel were shown, which can be pixel
Brightness data.Display panel can show secondary colour grey menu, can also show pure color grey menu.Secondary colour grey menu
Refer in RGB three primary colours the grey menu that at least two single primary colours are mixed and are shown.Secondary colour grey menu can be
Red indigo plant secondary colour grey menu, red green secondary colour grey menu, turquoise secondary colour grey menu or RGB secondary colour grayscale are drawn
Face.Pure color grey menu refers to that the grey menu that any list primary colours are shown in RGB three primary colours, pure color grey menu can be
Red grey menu is also possible to green grey menu, can also be blue grey menu.
Specifically, under preset gray scale, display panel display detection picture, by image collecting device to detection picture into
Row is taken pictures, and the image of detection picture is obtained.And to the corresponding brightness data of each pixel extraction of detection picture image.Image
The brightness data extracted is sent to data processing equipment by acquisition device, i.e. data processing equipment gets the bright of detection picture
Degree evidence.For example, detection picture can only include secondary colour grey menu, then the brightness data for detecting picture is secondary colour grayscale
The corresponding brightness data of picture.Detection picture also may include secondary colour grey menu and single primary colours grey menu, then detects picture
The brightness data in face is the corresponding brightness data of secondary colour grey menu brightness data corresponding with single primary colours grey menu.
S120, according to the preset luminance factor of the corresponding each single primary colours of secondary colour and brightness data, determine three primary colours
Brightness data.
Wherein, secondary colour refers to that at least two single primary colours are mixed and generated in RGB three primary colours, generate secondary colour
Each single primary colours be preset with corresponding luminance factor.Specifically, according to the preset brightness of the corresponding each single primary colours of secondary colour
Coefficient and the brightness data for detecting picture, determine the brightness data of three primary colours.For example secondary colour is generated by red and green mixing
, then the brightness data for detecting picture includes the brightness data of red green secondary colour grey menu and the brightness number of blue grey menu
According to.The corresponding red of the secondary colour is preset with red luma coefficient, and the corresponding green of the secondary colour is also preset with Green brightness system
Number.The brightness number of red grey menu can be determined according to red luma coefficient and the brightness data of red green secondary colour grey menu
According to according to the brightness data of the determining green grey menu of Green brightness coefficient and the brightness data of red green secondary colour grey menu.
The brightness of the brightness data of red grey menu, the brightness data of green grey menu and blue grey menu has been determined respectively
Data.
S130, the brightness data according to three primary colours determine the corresponding offset data of display panel.
In the ideal case, the brightness data and indigo plant of the brightness data of the red grey menu determined, green grey menu
The brightness data of color grey menu should be consistent with the brightness data under preset gray scale.Since technological level and raw material are pure
The reasons such as degree cause picture uneven and generate mura, and there are deviations for the pixel RGB three primary colours brightness data of actually detected picture.
For example, preset gray scale is 60, the corresponding R gradation value of actually detected picture, G gradation value and B gradation value are greater than
Or less than 60.Then according to the brightness data of red grey menu, the brightness data of green grey menu and blue grey menu
Brightness data determines the corresponding offset data of display panel, so that picture shown by display panel can achieve preset gray scale
Corresponding object brightness data.
In the present embodiment, by shooting secondary colour grey menu, and according to the bright of the corresponding each single primary colours of secondary colour
Degree coefficient obtains the brightness data of three primary colours, shortens the shooting time of CCD camera, reduces time cost, solves to obtain
When Mura offset data the technical issues of inefficiency.
