, can be to avoid there is the case where brightness irregularities after luminance compensation in domain in second direction.
Technical solution of the present invention is described further below with reference to specific embodiment:
Because electro-luminescence display device is current mode device, on the direction from close to driving circuit to far from driving circuit,
Electric current gradually decreases, and shows display area brightness and gradually decreases, the inconsistent of brightness occurs in the different location in display area
Property, affect the display effect of electro-luminescence display device.In order to be compensated to brightness irregularities situation, the invention proposes
A kind of luminance compensation scheme realizes the compensation to brightness irregularities situation using the data of existing DeMura circuit.
The luminance compensating mechanism of the present embodiment can be obtained independently of DeMura circuit with DeMura circuit connection
The data of DeMura circuit also can integrate in DeMura circuit.
DeMura circuit is carried out using display data of the demura technology to the sub-pix in electro-luminescence display device
When compensation, takes pictures first with CCD (charge-coupled device) camera to display area, obtain the original bright of each sub-pix
Degree evidence and mura information.It is calculated by the original luminance data to each sub-pix, obtains DeMura offset data.
The calculation formula of existing DeMura offset data is y1=ax1+b, wherein y1 is DeMura offset data, and a is
Preset compensating gain, b are DeMura deviant, and x1 is the average brightness data of the sub-pix of every block, DeMura
Deviant b is the existing common parameter of demura technology, and the present embodiment repeats no more the acquisition process of DeMura deviant.
When carrying out demura compensation, display area is generally divided into multiple smaller block, such as by viewing area
Domain is divided into the block of multiple 4*4, i.e., every block includes the sub-pix of 4 rows 4 column, since the block of division is smaller,
It is compensated mainly for mura, the brightness irregularities situation bigger for otherness cannot achieve compensation, therefore, this implementation
Example needs for be divided into display area multiple biggish compensatory zones, each benefit when compensating to brightness irregularities situation
Repaying region includes multiple block.
Due to the electric current of electro-luminescence display device be from close to the electro-luminescence display device driving circuit to
It is gradually decreased on first direction far from the driving circuit, therefore, the brightness of display area is gradually to drop in a first direction
Low, the brightness of display area is not in decline substantially in the second direction vertical with first direction, if in second direction
On mark off multiple compensatory zones arranged side by side, then the luminance compensation data of multiple compensatory zone may be not identical, root
The mesh that improvement brightness irregularities situation may be not achieved in luminance compensation is carried out to compensatory zone according to the different luminance compensation data
, therefore, display area is divided into multiple compensatory zones by the present embodiment in a first direction, and compensatory zone is in second direction
On length be equal to the length of the display area in this second direction, there is no arrange side by side in a second direction in this way
, can be to avoid there is the case where brightness irregularities after luminance compensation in multiple compensatory zones of cloth in second direction.
By taking the resolution ratio of display area is 1440 × 2560 as an example, i.e., display area includes 1440 × 2560 sub-pixes,
Display area can be divided into 16 1440 × 160 compensatory zones, i.e., each compensatory zone includes 1440 × 160 Asias
Pixel.Certainly, the number of compensatory zone is not limited to 16, can be adjusted according to the actual situation.
Specifically, each benefit can be calculated using following formula on the basis of calculating the formula of DeMura offset data
Repay the luminance compensation data in region: y=ax+b+c, wherein y is luminance compensation data, and a is preset compensating gain, and b is
DeMura deviant, x are the average brightness data of the sub-pix of each compensatory zone, and c is luminance compensation deviant.
Wherein it is possible to which the average brightness data x1 of the multiple block for including according to each compensatory zone obtains the compensation
The average brightness data x in region, specifically, the average brightness data x of each compensatory zone are equal to the average brightness of multiple block
The number for the block that the sum of data x1 includes divided by the compensatory zone.
Wherein, luminance compensation deviant c can be to refer to DeMura deviant b, in a specific example, can calculate every
The average value of the DeMura deviant for multiple block that one compensatory zone includes, using its value as luminance compensation deviant,
It can be after the average value of DeMura deviant for multiple block that each compensatory zone includes be calculated, according to setting
Rule obtains luminance compensation deviant after converting to the average value.Specifically, the deviant of each compensatory zone can be 8
Bit data.
Certainly, in the calculation formula for calculating luminance compensation data y, y=ax+b+c, x can also be each compensatory zone
Central point sub-pix original luminance data, can from DeMura circuit obtain each sub-pix original luminance data
The original luminance data of the sub-pix of the central point of the middle each compensatory zone of determination.
In the luminance compensation data for obtaining each compensatory zone, can according to luminance compensation data to each compensatory zone into
Row luminance compensation.
In the present embodiment, the original luminance data of sub-pix is obtained from DeMura circuit, according to the original bright of sub-pix
Degree carries out brightness benefit to each compensatory zone according to the luminance compensation data for calculating each compensatory zone, according to luminance compensation data
It repays, can be in the case where not increasing the hardware cost of electro-luminescence display device, while realizing that demura is compensated and to brightness
The compensation of uneven situation, saves time cost and economic cost.
Further, all there is (ax+b) in the formula due to calculating luminance compensation data and DeMura offset data, because
This, can further save calculating process, and luminance compensation data are directly determined using DeMura offset data.Specifically, may be used
To calculate the luminance compensation data y of each compensatory zone according to formula y=k+c, wherein k is average DeMura offset data, and c is
Luminance compensation deviant.
Wherein it is possible to which the DeMura offset data of the multiple block for including according to each compensatory zone obtains the compensation
The average DeMura offset data in region, specifically, the average DeMura offset data of each compensatory zone are equal to multiple block
The sum of the DeMura offset data block that includes divided by the compensatory zone number.
Wherein, luminance compensation deviant c can be to refer to DeMura deviant b, in a specific example, can calculate every
The average value of the DeMura deviant for multiple block that one compensatory zone includes, using its value as luminance compensation deviant,
It can be after the average value of DeMura deviant for multiple block that each compensatory zone includes be calculated, according to setting
Rule obtains luminance compensation deviant after converting to the average value.Specifically, the deviant of each compensatory zone can be 8
Bit data.
In the present embodiment, DeMura offset data is obtained from DeMura circuit, is calculated according to DeMura offset data every
The luminance compensation data of one compensatory zone carry out luminance compensation to each compensatory zone according to luminance compensation data, can be not
In the case where the hardware cost for increasing electro-luminescence display device, while realizing that demura is compensated and to brightness irregularities situation
Time cost and economic cost are saved in compensation.
