First, 6 liquid crystal displays are selected with 55 cun of liquid crystal display random samplings of batch from 3000 of arrival certain companies；It will take out
6 liquid crystal displays that sample goes out are assembled into 6 complete machines, and model machine is checked as this batch initial workpiece.
As shown in figure 3, data acquisition is carried out in special darkroom, by CCD camera, PC, Special Signal-generator group heterodyne
Lighting system runs dedicated De-Mura processing routines by PC machine and takes pictures, and gradually completes 6 complete machines in basic, normal, high ash
Raw data acquisition when rank signal.
As shown in figure 4, every complete machine initial data is divided into mn block by same size, each block initial data is by bright
Information Y is spent, color coordinate information (Cx, Cy is used to indicate) composition corresponds to complete machine initial data after the combination of mn blocks.
The mn block datas of the present embodiment 1-6 platform complete machines are expressed as Y1_mn, Cx1_mn, Cy1_mn/ .../Y6_mn,
Cx6_mn, Cy6_mn, this batch mn block typical case mura data are obtained using mean value method：
Wherein, i is that this batch initial workpiece checks that model machine quantity, value are 1~6；Mn is the number of blocks of every model machine, according to
Precision difference value is different, and m, n value range are 1~m, 1~n, and the equal value 16 of the present embodiment shares 256 blocks, similarly hereinafter.
After each block typical case mura data of this batch obtain and the correspondence block typical data of last batch uses differential technique
It is compared, if in control threshold range, without compensation data, data and software organization are achieved by upper batch for difference
Batch production；If difference carries out compensation data beyond control thresholding, using De-Mura algorithms.
ΔYMN=this crowd of YTypical mnAbove criticize YTypical mn
ΔCXMN=this crowd of CX typical case mnAbove criticize CX typical case mn
ΔCYMN=this crowd of CY typical case mnAbove criticize CY typical case mn

It holds as complete machine highlights block；Marginal zone is brightness lowermost extent, by De-Mura algorithms and compensation data, realizes that marginal zone is arrived
The brightness linear of center is promoted, and is ensured picture uniformity, is prevented jump in brightness, influence user experience.
YK=YMarginal zone+K*ΔY
A certain block brightness of the YK between marginal zone, center, K value ranges area between 1~marginal zone, center
Block sum；
Chromaticity coordinates data CX/CY is controlled by a certain range, and brightness number is carried out under conditions of ensureing uniformity of chromaticity
According to compensation.
Interpolated value operation is carried out to the brightness of each block and colouring information using De-Mura algorithms, peak load shifting passes through
It repeatedly takes pictures after cycle and confirms with subjective effect, ultimately form this batch effective compensation data.
As shown in fig. 6, in the present embodiment main program write-in emmc memories, De-Mura offset datas write-in eeprom is deposited
In reservoir, main program calls offset data when machine system works, and forms special liquid crystal screen drive signal, realizes complete machine De-
Mura functions.
The present embodiment reserved space in complete machine configuration file is used for offset data, can carry out batch compensation as needed
Data update；Corresponding eeprom storages are written by special journey tooling of writing before batch production in updated complete machine configuration file
Device realizes complete machine batch De-Mura for batch complete machine software transfer.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
All any modification, equivalent and improvement etc., should all be included in the protection scope of the present invention made by within refreshing and principle.
