    Abstract: A display apparatus including: a display screen including multiple light-emitting points and a first side, wherein light generated by the light-emitting points emits from the first side; and a microlens array provided on the first side of the display screen, the microlens array includes multiple microlenses arranged in an array, an orthographic projection of the microlens array on the display screen covers the display screen, and the display screen is provided on a focal surface of the microlens array. The focal lengths of the multiple microlenses increase sequentially from the center of the microlens array to the edge of the microlens array, so that a beam width of the light that is emitted from each light-emitting point of the display, transmits through the microlens array and is incident into a pupil of a human eye is less than a preset threshold.

    Abstract: The present disclosure relates to a display assembly, a display device and a driving method. The display assembly includes: a display panel provided with a plurality of pixel islands distributed in an array, any one of the pixel islands including sub-pixels continuously arranged along a set direction; and a lens layer arranged on a light exit surface of the display panel and including lenses arranged along the set direction. A lenticular lens pitch is not greater than a size of an opening of each pixel island in the set direction, and along the set direction, a sub-pixel pitch in each of the pixel islands is smaller than a half of the lenticular lens pitch. The lenticular lens pitch is equal to a sum of a size of each lenticular lens in the set direction and a distance between two adjacent ones of the plurality of lenticular lenses.
