Abstract
The present disclosure provides a display apparatus, including: a plurality of pixels, at least one of which includes a red sub-pixel, a green sub-pixel, a first blue sub-pixel and a second blue sub-pixel. Blue light emitted by the first blue sub-pixel has a wave band of 400˜540 nm and blue light emitted by the second blue sub-pixel has a wave band of 420˜580 nm. The red sub-pixel and the green sub-pixel are combined with the first blue sub-pixel or the second blue sub-pixel to perform a RGB three-primary-color display. The present disclosure further provides a display method for the display apparatus.
