Image data refers to that the digital signal being input in sequence controller TCON, image data input frame by frame, to this
Image data analyzing obtains raw pixel data, in a kind of existing technology, in the raw pixel data, that is, picture element matrix
Each sub-pixel is input to the pixel value of each sub-pixel by being input to TCON in the specific pixel value of the corresponding display of each frame
In image data directly determine, raw pixel data is not handled, such mode is led by the polar influence of sub- picture element
Sub- picture element polarity is caused to be easy to produce crosstalk, the negative effects such as bright concealed wire.
And in the present embodiment, by the way that raw pixel data is handled, obtain further first luma data and
