The channel value of the object pixel can be increased to 1.92 times, for example, the channel value of tri- chrominance channel object pixel RGB be (0, G,
0) channel value of tri- chrominance channel object pixel RGB after, then adjusting is (0,1.92G, 0), meanwhile, it is corresponding to close white channel
Sub- display unit, alternatively, the channel value of white channel is determined as 0.And if object pixel is multichannel pixel, it can be first
The minimum value channel value of the white channel of object pixel being determined as in the channel value of multiple primary color channels, then again will be multiple
The channel value of white channel is individually subtracted in the channel value of primary color channels, for example, the channel value of tri- chrominance channel object pixel RGB is
(R, G, B), then the channel value W=MIN (R, G, B) of white channel, channel value Rt, Gt, Bt of three chrominance channels after determining distinguish
Are as follows: Rt=R-W, Gt=G-W, Bt=B-W.
Mode three obtains the channel value of multiple primary color channels of object pixel in image to be displayed；If object pixel is
Single channel pixel adjusts multiple primary colours of object pixel then according to the light transmittance of the corresponding sub- display unit of each color channel
