US 9,286,857 B2 · Display apparatus and method for transforming color thereof

Abstract

A display apparatus and a method for transforming color thereof are provided. The display apparatus includes a display panel having a red sub-pixel, a blue sub-pixel, a green sub-pixel and a white sub-pixel, a driver circuit for driving the red sub-pixel, the blue sub-pixel, the green sub-pixel and the white sub-pixel, and a data processing unit. The data processing unit receives a red original data, a blue original data and a green original data to produce a red reference data, a green reference data and a white reference data to the driver circuit as a red data, a green data and a white data, and regulate a produced blue reference data thereof according to a blue component brightness corresponding to the white reference data to provide the a blue data to the driver circuit.
