Image transmitting interface 22 is used to obtain Mura compensating image data from GPU data processing module 11 and be fitted by SPI
Orchestration 5 is burned onto the Flash IC41 of mould group 4.
GPU data processing module 11 is obtained using the parallel processing capability of GPU according to the brightness value matrix of positioning image frame
The picture mapping relations of camera 3 Yu mould group 4 are taken, and calculate the Mura assessed value of picture to be repaired according to picture mapping relations, are sentenced
Whether the gray-scale intensity of picture to be repaired of breaking meets the requirements, and calculates the Mura offset data matrix of picture to be repaired.
GPU image synthesis module 12 is used for the brightness of the Mura offset data matrix of picture to be repaired and picture to be repaired
Value matrix synthesis, forms Mura compensating image data.
GPU image output interface 13 is sent to mould group 4 for Mura compensating image data to be converted to picture signal.GPU
The interface type of image output interface 13 determines by the model and specification of GPU1, including but not limited to DP, VGA, HDMI, DVI.
As shown in Fig. 2, the step of realizing the mould group color spot restorative procedure based on PC GPU using apparatus of the present invention is as follows:
1) data flow for the positioning picture that the image zooming-out module 21 of CPU2 is shown from the mould group 4 that camera 3 obtains shooting, and
Data flow is decoded, the brightness value matrix of positioning picture is generated, then the brightness value matrix for positioning picture is sent to GPU number
According to processing module 11.
2) GPU data processing module 11 calculates camera 3 according to the brightness value matrix of positioning picture and maps to 4 end picture of mould group
Relationship.Mapping mode includes angle point mapping and puts to mapping.
3) data flow for the picture to be repaired that the image zooming-out module 21 of CPU2 is shown from the mould group 4 that camera 3 obtains shooting,
And be decoded data flow, the brightness value matrix of picture to be repaired is generated, then the brightness value matrix of picture to be repaired is sent
To GPU data processing module 11.
3 shooting picture of camera includes positioning picture and picture to be compensated, and the resolution ratio of image frame data is 3840*
2160.Positioning picture refers to that the picture for calculating camera to mould group end picture mapping relations, picture to be compensated refer to certain
One grayscale pure color picture.It should be noted that the image frame data can be gray-value image data, it is mono- to be also possible to RGB
Color image data.
4) GPU data processing module 11 turns the brightness value matrix of the picture to be repaired of acquisition according to picture mapping relations
It is changed to panel end brightness value matrix.
5) GPU data processing module 11 calculates Mura assessed value, and Mura assessed value is a class value, represents different judgements and refers to
Mark, system determine that process continues to walk downward or terminates according to whether assessed value meets index.
6) within preset range, if reparation terminates Mura assessed value, step 11 is gone to；If Mura assessed value is not default
Within range, step 7) is gone to.
7) GPU data processing module 11 calculates Mura offset data square according to the panel end brightness value matrix of picture to be repaired
Battle array.The specific steps are first subtract background data and obtain defective data, repair parameter multiplied by Demura with defective data, obtain
Mura offset data matrix.It can be a certain reparation Coefficient m that Demura, which repairs parameter, be also possible to be with defective data same order
Matrix number.
8) GPU image synthesis module 12 receives the panel end brightness value matrix and Mura offset data square of picture to be repaired
Battle array, Mura offset data matrix is synthesized with panel end brightness value matrix, is formed Mura and is compensated image.Compensating image signals can be with
It is generated in such a way that the Mura offset data matrix of multiple and different grayscale is according to linear interpolation.
Such as:
The corresponding grayscale of Mura offset data matrix 1 is 50, and the submatrix of its a 3*3 size is
- 1,5,6
3,2,0
6,7,8
The corresponding grayscale of Mura offset data matrix 2 is 100, and the submatrix of its same position is
3,7,8
7,2,0
8,9,6
If the submatrix of brightness value same position is
75,75,75
75,75,75
75,75,75
In the way of linear interpolation, the brightness value of the Mura compensation image same position of generation is
Mura offset data matrix group is also possible to default in the Demura Table of BlockSize, i.e. Mura compensates number
According to matrix group set.
9) Mura compensation image is converted to picture signal video stream to mould group 4 by GPU image output interface 13.
10) camera 3 continues to shoot the mould group 4 after color spot is repaired and shows that picture as picture to be repaired is sent to CPU2
Image zooming-out module 21.Return step 1) until repairing in step 6) terminates.
11) Mura offset data matrix, then be sent to by the Mura offset data matrix if it exists of GPU data processing module 11
The SPI interface 22 of CPU2, Mura compensating image data that SPI interface 22 will acquire simultaneously are burned onto mould group by SPI adapter 5
Flash IC41 solidifies.
In the prior art, as shown in figure 3, repairing the SPI22 that calculated Mura offset data matrix passes through CPU2 every time
Interface is sent to Flash IC41, then picture of the display of mould group 4 by reparation.And Mura offset data matrix is burnt to
The time of Flash IC41 is longer, debugs one piece of mould group and needs repeatedly to repair, generally requires time-consuming 60s/ piece.
And in the present invention, the GPU image output interface that calculated Mura offset data matrix passes through GPU1 is repaired every time
13 are sent directly to mould group 4, picture of the display of mould group 4 by reparation, it is not necessary that Mura offset data matrix is burnt to Flash
IC41 only need to will be burnt to Flash IC41 solidification by the Mura offset data matrix assessed after the completion of reparation.Utilize this
Invention, debugs one piece of mould group and needs 30s/ piece.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the principle of the present invention, it can be devised by several improvement, these improvement also should be regarded as the present invention
Protection scope.
The content that this specification is not described in detail belongs to the prior art well known to professional and technical personnel in the field.
