Using reference color coordinate value as the longitudinal axis.
Step S204 obtains the level deviation of the predetermined level Yu the fiduciary level.
In one embodiment, actual color coordinate value is the difference ash parsed according to the picture that display panel is currently shown
Rank is worth the chromaticity coordinates value of corresponding image；Preset reference color coordinate value is in advance in display device storage inside and by colour temperature
The corresponding reference color coordinate value of the different grayscale values of correction.Since chromaticity coordinates value determines the colour temperature of image, identical chromaticity coordinates value
Reflect identical colour temperature, but when display device generation colour cast needs to be adjusted, identical chromaticity coordinates then corresponds to different
Grayscale value；The grayscale value of image is determined by the drive level of display panel；By the current practical color of the display panel parsed
Coordinate value is compared with the standard actual color coordinate value being stored in display device, corresponding available identical chromaticity coordinates
The corresponding grayscale value deviation of value further determines that the deviation of the level of driving display panel according to grayscale value deviation.
In one embodiment, red picture as shown in Figure 9 and Figure 10 and blue picture grayscale value and chromaticity coordinates value
The comparison of homologous thread, chromaticity coordinates value determine the colour temperature of image, in the case where guaranteeing that color temp is constant, identical chromaticity coordinates
Corresponding grayscale value generates deviation, then the level deviation of driving display panel is further determined that according to grayscale value deviation, described
Level deviation is the level for driving display panel and the corresponding level adjustment value of grayscale value deviation.
Step S205 adjusts the actual color coordinate value according to the level deviation.
In one embodiment, the drive level that display panel is adjusted according to level deviation, so that display panel was shown
Image complies with standard chromaticity coordinates value；Under level driving after adjustment, the adjusting of the chromaticity coordinates value to display image is realized, so that
The colour temperature effect of image is shown normally.
In one embodiment, the actual color coordinate of display panel displayed image is adjusted according to the level deviation
Value includes:
According to the level deviation, drive level corresponding with image gray-scale level value is adjusted；
Display panel is driven by the drive level after adjusting, the practical color of the image after obtaining corresponding adjust is sat
Scale value.
In one embodiment, level deviation is corresponded to according to each grayscale value of image to adjust shown by display panel not
With the actual color coordinate value of gray scale image.
Through this embodiment, multiple data points are acquired and analyze, carry out colour cast calibration that can be more accurate, in due course；?
When display device colour cast occurs after being used for a long time, user can star colour temperature automatic control program, complete the offline automatic of colour cast
Calibration, is not needing to return factory-run school just, reduces repair rate, the off-line calibration of colour cast can be completed in client, it is ensured that at television image
In the state of " Chang Xin "；Determine that image in the deviation of the corresponding drive level of identical chromaticity coordinates value, is adjusted by the parsing to image
The drive level of display panel is saved, and then adjusts the chromaticity coordinates value of display image, improves the picture display effect of display device, prolongs
The service life of long display device improves picture quality.
