1. A display assembly, comprising:
a dimming array and a pixel array which are stacked together,
wherein: the dimming array comprises a plurality of dimming units arranged in an array, the pixel array comprises a plurality of pixel units arranged in an array, each of the plurality of dimming units corresponds to at least one of the plurality of pixel units, and different dimming units correspond to different pixel units, respectively;
the display assembly further comprises: a first driver chip configured to drive the dimming array;
a number of output channels of the first driver chip is equal to a number of columns of dimming units in the dimming array, and each output channel of the first driver chip is connected to one column of dimming units; and
the display assembly further comprises a second driver chip configured to drive the pixel array, wherein: each of the plurality of pixel units comprises a plurality of sub-pixels; and a number of output channels of the second driver chip is equal to a number of columns of sub-pixels in the pixel array, and each output channel of the second driver chip is connected to one column of sub-pixels,
wherein: the first driver chip and the second driver chip are of a same type; and the number of output channels of the first driver chip is smaller than the number of output channels of the second driver chip,
wherein the display assembly further comprises a controller, and the controller is configured to: transmit a plurality of data signals to corresponding sub-pixels through the output channels of the second driver chip according to a to-be-displayed picture; convert the plurality of data signals into a plurality of dimming signals corresponding to the number of output channels of the first driver chip according to the ratio of the resolution of the dimming array to the resolution of the pixel array; and transmit the plurality of dimming signals to corresponding dimming units through the output channels of the first driver chip to adjust light transmittance of the dimming units, and
wherein the controller is configured to: process the plurality of data signals to extract information therein; combine the data signals of sub-pixels of a same color corresponding to a same column of dimming units, according to the number of input channels of the first driver chip, to form a plurality of dimming sub-signals; and pack three dimming sub-signals corresponding to a same column of dimming units to form the plurality of dimming signals.
