Description

CROSS-REFERENCE TO RELATED APPLICATIONS This application is a continuation of International Application No. PCT/CN2021/092082 filed on May 7, 2021, which claims priority to Chinese Patent Application No. 202010422318.4 filed on May 15, 2020. The disclosures of the aforementioned applications are hereby incorporated by reference in their entireties. TECHNICAL FIELD This disclosure relates to the field of image processing and display, and in particular, to a display apparatus, system, and method. BACKGROUND In an image display scenario, three dimensional (3D) display can provide a more real image to a viewer than two dimensional (2D) display. Currently, the viewer needs to wear an auxiliary device such as special glasses or a helmet while watching a common 3D movie or 3D television in the market. Viewing images of a left eye and a right eye are separated by using the auxiliary device, so that a brain of a user can combine a stereoscopic image with a feeling of depth, thereby generating a stereoscopic 3D movie viewing effect. A naked-eye 3D technology can control a display to generate different image sources to the left eye and the right eye of the viewer without requiring the user to wear the auxiliary device, thereby generating a 3D viewing effect. In a naked-eye 3D technology based on binocular parallax, because of a vision difference between the left eye and the right eye, different areas of a display panel can be respectively viewed by the left eye and the right eye within a specific observation range and at a specific observation angle, and visual images of the left eye and the right eye of the viewer are separated, that is, images that simultaneously enter the two eyes of the user are different. The display panel separately displays corresponding image sources in viewing ranges of the left eye and the right eye, and a 3D display effect is implemented by using corresponding depth information that is generated by processing of a human brain. The image sources seen by the left eye and the right eye are still 2D image sources, and the 3D movie viewing effect originates from a difference between two 2D images that is perceived by the human brain. Focuses of the human eyes are still on one plane, and are not at different distances like actually viewing a 3D object in reality, and focal lengths of the human eyes also have a relative distance. Therefore, real depth information cannot be generated, and a problem of a poor 3D display effect exists. In addition, the display panel separates the left eye and the right eye by dividing an area. Therefore, a problem that a final display image resolution is low exists. SUMMARY Embodiments of this disclosure provide a display apparatus, system, and method, where a 3D image is displayed based on real depth information, so as to improve a display effect of the 3D image and a resolution of the 3D image. To resolve the foregoing technical problems, the embodiments of this disclosure provide the following technical solutions: According to a first aspect, an embodiment provides a display apparatus, including a multi-focus image generation unit and a time sequence control unit. The multi-focus image generation unit is connected to the time sequence control unit. The time sequence control unit is configured to generate a plurality of time sequence instructions that belong to a first switching period, and send the plurality of time sequence instructions that belong to the first switching period. The multi-focus image generation unit is configured to receive the plurality of time sequence instructions that belong to the first switching period from the time sequence control unit, and generate a plurality of corresponding three-dimensional (3D) image blocks at different distances based on the plurality of time sequence instructions, where the plurality of 3D image blocks respectively have different depth information, and the plurality of 3D image blocks belong to a 3D image for display in the first switching period. The display apparatus provided in this embodiment of this application includes a multi-focus image generation unit, where the multi-focus image generation unit may generate a plurality of 3D image blocks with depth information based on time sequence control. Therefore, a 3D image formed by the apparatus has real depth distribution, and a display effect of the 3D image is better than that of a 3D technology based on 2D binocular parallax. In addition, in this embodiment of this application, the 3D image block is generated by the apparatus only based on time sequence control, and a resolution of an image source is not reduced. Therefore, a resolution of the 3D image is better than an image resolution of the 3D technology based on 2D binocular parallax. In a possible implementation, the time sequence control unit is further configured to generate a plurality of time sequence instructions that belong to a second switching period, and sends the plurality of time sequence inst
