Abstract
A display apparatus. The display apparatus includes a back light module; a light transmission direction controller on a light emitting side of the back light module; and a plurality of subpixels on a side of the light transmission direction controller away from the back light module, each individual one of the plurality of subpixels including a light transmissive part and a light blocking part. The back light module is configured to emit light toward the plurality of subpixels. The light transmission direction controller is configured to independently adjust a grayscale of each individual one of the plurality of subpixels by independently controlling a light distribution ratio between a first portion of light transmitted through the light transmissive part and a second portion of light blocked by the light blocking part in each individual one of the plurality of subpixels.
