In order to ensure that technical solutions of the embodiments of the disclosure may be understood readily and better by those skilled in the art, a naked-eye three-dimensional display method, a naked-eye three-dimensional display device, and a terminal equipment according to embodiments of the disclosure may be described in detail hereinafter by referring to the drawings.

According to a general inventive concept of the embodiments of the disclosure, as illustrated in FIG. 1(a) to FIG. 3, a panel positioning assembly, which is used for a panel 2, is provided in an embodiment of the disclosure, comprising: a side frame 1 at least partially provided at a periphery of the panel 2; and a plurality of positioners 3 (such as positioning blocks, and the like) detachably provided on the side frame 1 and configured to position the panel 2.

By providing the plurality of positioners 3 which are detachable, a same backlight module may match with (e.g, be in positive fit with) different positioners 3 which are adapted to differently sized panels 2, and be assembled together; as such, when an original panel 2 is replaced by a different panel 2 having a different size, it is only required to exchange positioners 3 so as to change specific size of a bearing region of the side frame 1 for bearing the panel 2, without replacing the backlight module, thus saving the cost.

There may be various specific structural forms of the positioners 3, as long as the positioners 3 may implement an appropriate positioning of a panel 2 of corresponding size on the side frame 2. In the embodiment of the disclosure, as illustrated in FIG. 1(a), the side frame is provided with four sides, with a corresponding one of the plurality of positioners being provided on each of the four sides.

And specific amounts and specific structural forms of the positioners 3 on each side may also be provided depending on practical requirements.

In an embodiment, by way of example, as illustrated in FIG. 1(a), the plurality of positioners 3 are provided respectively at corners of the side frame 1 which corners function as junctions of adjacent sides of the side frame 1 abutting against each other, respectively.

As illustrated, at least one positioner of the plurality of positioners 3 comprises a first connection block 31 and a second connection block 32. Each of the first connection block and the second connection block extends respective widths in directions as indicated by corresponding arrows, specifically as illustrated in FIG. 1(a), a width of the first connection block 31 refers to a measure of a dimensional scope thereof in which the first connection block 31 extends in a ‘Y’ direction as illustrated, and a width of the second connection block 32 refers to a measure of a dimensional scope thereof in which the second connection block 32 extends in a ‘X’ direction as illustrated. In an exemplary embodiment, each of the first connection block and the second connection block is configured to be defined/restricted within (i.e., failing to go beyond) respective width range defined collectively by both an inner wall and an outer wall of a respective side of the side frame 1 on which it is located; for example, each of the first connection block and the second connection block is arranged to be aligned with the respective side of the side frame 1 on which it is located; and more specifically, by way of example, an orthographic projection of each of the first connection block and the second connection block on the panel falls within an orthographic projection of the respective side of the side frame 1 on which it is located, on the panel. By changing a width of at least one of the first connection block and the second connection block provided on at least one of the plurality of positioners 3 in a form of L shape, the size of the bearing region of the side frame 1 for bearing the panel 2 is then changed, so as to facilitating inserting/embedding and bearing differently sized panels 2 into the side frame 1.

A Specific size of the first connection block 31 may for example be set to be the same as or different from a specific size of the second connection block 32, such that they are adapted to positioning of differently sized panels 2.
