Abstract

The present application provides a light-field display apparatus. The apparatus includes: a display screen, the display screen including N display regions, each display region of the N display regions including M light-emitting points, and light-emitting points at a corresponding position of the N display regions being a light-emitting point group; driving circuits, configured to drive the light-emitting points to emit light; a lens group including at least one lens, the light-emitting points in the N display regions forming view zones corresponding one by one to the N display regions by the lens group, wherein light-emitting points belonging to a same light-emitting point group in the N display regions are driven by a same driving circuit, the N view zones are not overlapped with each other, and both N and M are positive integers greater than 1.

Claims (15)

1. A light-field display apparatus, comprising:

k display screens, and k is a positive integer greater than or equal to 1, wherein for each display screen of the k display screens, the each display screen including N display regions, each display region of the N display regions including M light-emitting points, and light-emitting points at a corresponding position of the N display regions being a light-emitting point group;

driving circuits, configured to drive the light-emitting points to emit light;

a lens group including at least one lens, wherein for the each display screen, the light-emitting points in the N display regions forming N view zones corresponding one by one to the N display regions by the lens group,

wherein light-emitting points belonging to a same light-emitting point group in the N display regions are driven by a same driving circuit, and for the each display screen, N view zones of the each display screen are not overlapped with each other, and both N and M are positive integers greater than 1,

wherein in a case where k is greater than 1, corresponding view zones of the N display regions of the k display screens overlapping with each other.

2. The light-field display apparatus of claim 1 , wherein

each light-emitting point is one pixel, each display region includes M pixels and the N display regions have M light-emitting point groups;

the N display regions form the N view zones by one lens, or form the N view zones by a plurality of lenses;

pixels of the N display regions are arranged in a same manner.

3. The light-field display apparatus of claim 1 , further comprising switches connecting at least one display region of the N display regions and the driving circuits of the display region and configured to turn on or turn off driving of the display region by the driving circuits.

4. The light-field display apparatus of claim 3 , wherein the connecting includes:

connecting the M light-emitting points in the display region to the corresponding driving circuits respectively by M switches.

5. The light-field display apparatus of claim 1 , wherein the each display screen includes M pixels, each pixel of the M pixels comprising N light-emitting points formed by a mask, the N light-emitting points of each pixel corresponding to one light-emitting point group, the each display screen comprising M light-emitting point groups, each display region of the N display regions is formed by the light-emitting points at corresponding positions in the M light-emitting point groups, wherein

the M pixels respectively correspond to M lenses, and the light-emitting points in the N display regions form N view zones corresponding to the N display regions one by one by the M lenses.
