Background Art

[0002] Light field display technology is a technology that reproduces an original object by recording the three-dimensional position information of object information in the propagation process and has richer image information. At the current stage, due to the sense of reality brought by three-dimensional display and depth information, more people are researching it, enriching our lives, and enabling observers to view the three-dimensional information of each side of an object as if they were looking at the actual scenery without the need to use any tools.

The drawings of the embodiments of this disclosure relate only to the structures relating to the embodiments of this disclosure; for other structures, conventional designs may be referenced.

[0031] The proportions in the drawings in this disclosure may, but are not limited to, those shown in the drawings for reference in actual processes. For example, the ratio of channel width to length, the thickness and spacing of each film layer, and the width and spacing of each signal line may be adjusted according to actual requirements. The number of pixels on the display substrate and the number of subpixels in each pixel are not limited to those shown in the drawings, and the drawings described in this disclosure are merely schematic diagrams of the structure. One aspect of this disclosure is not limited to the shapes or numerical values ​​shown in the drawings.

This is for the purpose of describing and simplifying this specification, and is not intended to indicate or suggest that the described apparatus or element has a specific orientation or must be configured and operated in a specific orientation. Therefore, it is not intended to limit this disclosure. The positional relationships of the components may be appropriately changed depending on the direction in which each component is described. Therefore, the terms used may be appropriately changed in some cases, not limited to those described in the specification.

[0034] In this specification, unless explicitly stated or limited, the terms “attach,” “connect,” and “connect” should be understood broadly. For example, this could be a fixed connection, a removable connection, or an integrated connection; a mechanical connection, or an electrical connection; a direct connection, an indirect connection via a linker, or internal communication between two elements. Those skilled in the art will understand the specific meaning of these terms in this disclosure depending on the specific context.

[0035] In this specification, "electrically connected" includes cases where components are connected via an element having an electrical function. The "element having an electrical function" is not particularly limited and only needs to be capable of transmitting and receiving electrical signals between the connected components. Examples of "elements having an electrical function" include not only electrodes and wiring, but also switching elements such as transistors, resistors, inductors, capacitors, and elements with various other functions.

[0036] In this specification, "parallel" refers to a state in which the angle formed by two straight lines is between -10° and 10°, and therefore also includes a state in which the angle is between -5° and 5°.

For example, the materials used to form the precursors of multiple types of structures placed in the same layer may be the same, and the materials used to form the final structures may be the same or different.

[0039] In this specification, triangles, rectangles, trapezoids, pentagons, or hexagons are not strictly defined and may be approximate triangles, rectangles, trapezoids, pentagons, or hexagons, and may have small deformations due to tolerances, as well as chamfers, arcs, and other deformations.

[0040] In this disclosure, "approximately" means that the boundary is not strictly defined and that numerical values ​​within the error range of the process and measurement are permitted.

[0041] The imaging device in optical field display products needs to have functions such as human gaze tracking, human image recognition, and human guidance, which complicates the structure of the imaging device and makes installation difficult. Therefore, embodiments of this disclosure provide a camera assembly.

As shown in Figure 1, the camera assembly 10 according to an embodiment of the present disclosure may include a circuit board 11 and at least one first camera 12 and at least one second camera 13 mounted on the circuit board.
