Filed: 2020-12-24
Abstract: A pixel structure, which is applied to a self-light-emitting display panel. The pixel structure comprises: a plurality of sub-pixels, wherein at least one of the plurality of sub-pixels comprises a plurality of sub-sub-pixels, and a partition layer is arranged between two adjacent sub-sub-pixels; and the light emission of the plurality of sub-sub-pixels is independently controlled. Where the display grayscale is relatively low, the density of a current flowing through a light-emitting device is also relatively low, and only some of sub-sub-pixels are controlled to emit light; since the light emission area of sub-sub-pixels is less than the light emission area of sub-pixels, the current density of the sub-sub-pixels is greater than the current density of the sub-pixels, and when a current density is relatively large, the stability of a light emission spectrum is better, and a displayed color is more accurate; and since a current density increases, the influence of electric leakage on the problem of uneven display is reduced, such that the problem of uneven display is greatly alleviated.
