Referring to FIG. 12A, in some embodiments, when a curve 1306 of the lens curved-surface 110 (not shown in the figure, referring to FIGS. 1A and 2 to 4B) formed on the cross section of the lens 100 is the hyperbola, the lens curved-surface 110 may face the pixel 300. Referring to FIG. 12B, in some embodiments, when a curve 1307 of the lens curved-surface 110 (not shown in the figure, referring to FIGS. 1A and 2 to 4B) formed on the cross section of the lens 100 is the ellipse, the lens curved-surface 110 may face away from the pixel 300. Optionally, an orientation relationship between the lens curved-surface 110 and the pixels 300 may be considered according to actual conditions such as process requirements.

In some embodiments, the pixel 300 may be a pixel for 3D display. Optionally, the pixel 300 may be set according to actual conditions such as process requirements, so that the pixel 300 may provide support in the aspect of display, for example, providing support for 2D display, 3D display and the like.

In some embodiments, the display panel 700 may realize 2D or 3D display. Optionally, all or part of the display panel 700 may realize 2D or 3D display; for example, all of the display panel 700 may realize 2D or 3D display; or, part of the display panel 700 may realize 2D or 3D display.

Referring to FIG. 13, embodiments of the present disclosure further provide a display 800, comprising the display panel 700.

In some embodiments, the display 800 may further comprise other components for supporting normal operation of the display 800, such as at least one of a communication interface, a framework, a control circuit and the like.

In some embodiments, whether the lens 100 comprises the lenticular lens 101 or the spherical lens 102 or has other shapes, at least one curve of a surface of the lens 100 macroscopically may be of a circular or noncircular shape, such as ellipse, hyperbola, parabola and other shapes. Optionally, at least one curve of the surface of the lens 100 microscopically may be of a noncircular shape, such as polygon and other noncircular shapes. Optionally, the shape of the lens 100 may be determined according to actual conditions such as process requirements, for example, the shape of the surface of the lens 100.

By adopting the lens, the grating, the display panel and the display provided by embodiments of the present disclosure, the shape of the lens curved-surface can be flexibly determined according to characteristics of the lens in the aspect of display, so that the shape of the lens curved-surface is no longer fixed and single, and is related to the characteristics of the lens in the aspect of display, thereby contributing to the improvement of display effect.

The above description and drawings sufficiently illustrate the embodiments of the present disclosure to enable those skilled in the art to practice them. Other embodiments may comprise structural, logical, electrical, process, and other changes. The embodiments represent only possible changes. Unless expressly required, individual components and functions are optional and the order of operations may be changed. Parts and features of some embodiments may be included in or substituted for parts and features of other embodiments. The scope of the disclosed embodiments includes the full scope of the claims, and all available equivalents of the claims. When used in the present disclosure, although the terms of “first”, “second”, etc. may be possibly used in the present disclosure to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another. For example, without changing the meaning of the description, a first element may be called as a second element, and similarly, the second element may be called as the first element, as long as all of “the first elements” that appear are consistently renamed and all of “the second elements” that appear are consistently renamed. The first element and the second element are both elements, but may not be the same element. Moreover, the terms used in the present disclosure are used to describe the embodiments only and not to limit the claims. As used in the illustration of the embodiments and the claims, unless clearly indicated in the context, the singular forms “a”, “an” and “the” are also intended to include the plural forms. Similarly, the term “and/or” as used in the present disclosure is meant to include any and all possible combinations of one or more of the associated listings. In addition, when used in the present disclosure, the term “comprise” and its variations “comprises” and/or “comprising”, etc., refer to the presence of stated features, integers, steps, operations, elements, and/or components, but does not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components and/or groupings of these. Without further limitations, an element limited by the phrase “comprises a . . . ” does not preclude the presence of additional identical elements in the process, method or device that includes the element. Herein, the difference of each embodiment from each other may be the focus of explanation. The same and similar parts among all of the embodiments may be referred to each other. For the method and product disclosed by the embodiments, if the method and product correspond to a method part disclosed by the embodiments, the description of the method part can be referred to for the related part.

Those skilled in the art may recognize that the units and algorithm steps of each example described in conjunction with the embodiments disclosed herein can be implemented in electronic hardware, or a combination of computer software and electronic hardware. Whether these functions are performed in hardware or software may depend on the specific application and design constraints of the technical solution. Those skilled in the art may use different methods for implementing the described functions for each particular application, but such implementations should not be considered beyond the scope of the embodiments of the present disclosure. Those skilled in the art may clearly understand that, for the convenience and brevity of description, the corresponding processes in the above method embodiments may be referred to for the working processes of the above systems, devices and units, which will not be repeated here.

In the embodiments disclosed herein, the disclosed method and product (including, but not limited to the apparatus and the device) may be realized in other ways. For example, the device embodiments described above are merely schematic. For example, the division of the units may be only a logical functional division, and may be an additional division manner in actual realization. For example, multiple units or components may be combined or integrated into another system, or some features may be ignored or not executed. In addition, the displayed or discussed mutual coupling or direct coupling or communication connection may be indirect coupling or communication connection through some interfaces, devices or units, and may be electrical, mechanical or other forms. The units described as separate components may or may not be physically separated, and the components shown as the units may or may not be physical units, that is, may be located in one place, or may be distributed on multiple network units. The present embodiments may be implemented by selecting some or all of the units according to actual needs. In addition, each functional unit in the embodiments of the present disclosure may be integrated into one processing unit, or each unit may exist physically alone, or two or more units may be integrated into one unit.
