1. A display device, comprising:
a plurality of ordinary pixels, respectively including a first color sub-pixel;
an auxiliary pixel, including a plurality of first color sub-pixels, wherein a light-emitting area in each of the plurality of first color sub-pixels in the auxiliary pixel and a light-emitting area in the first color sub-pixel of each of the plurality of ordinary pixels are the same with each other;
a frame, configured to define an active area in a non-rectangular shape, wherein the plurality of ordinary pixels and the auxiliary pixel are arranged in the active area; and
a driving chip, configured to receive a display data, wherein the display data includes a first color grayscale value configured to assign a first target luminance of the first color sub-pixel to one of the ordinary pixel;
wherein in response to the one of the ordinary pixel and the auxiliary pixel each receives display data with identical first color grayscale value, the driving chip is configured to generate one or more processed first color grayscale values according to the first color grayscale value, the one or more processed first color grayscale values are configured to assign a luminance to each of the plurality of first color sub-pixels of the auxiliary pixel, and the sum of the luminance of the plurality of first color sub-pixels of the auxiliary pixel is substantially equal to the first target luminance.
