Detailed Description

Hereinafter, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. In the case of conflict, the embodiments of the present disclosure and the features of the embodiments may be arbitrarily combined with each other.

The steps illustrated in the flow charts of the figures may be performed in a computer system such as a set of computer-executable instructions. Also, while a logical order is shown in the flow diagrams, in some cases, the steps shown or described may be performed in an order different than here.

Unless otherwise defined, technical or scientific terms used herein shall have the ordinary meaning as understood by one of ordinary skill in the art to which this disclosure belongs.

In the drawings, the size of each component, the thickness of layers, or regions may be exaggerated for clarity. Therefore, the embodiments of the present disclosure are not necessarily limited to the dimensions, and the shapes and sizes of the respective components in the drawings do not reflect a true scale. Further, the drawings schematically show ideal examples, and the embodiments of the present disclosure are not limited to the shapes or numerical values shown in the drawings.

The ordinal numbers such as "first", "second", "third", etc., in this disclosure are provided to avoid confusion among the constituent elements, and do not indicate any order, number, or importance.

In the present disclosure, for convenience, terms indicating orientation or positional relationship such as "middle", "upper", "lower", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like are used to explain positional relationship of constituent elements with reference to the drawings, only for convenience of description and simplification of description, and do not indicate or imply that the device or element referred to must have a specific orientation, be configured in a specific orientation, and be operated, and thus, should not be construed as limiting the present disclosure. The positional relationship of the components is changed as appropriate in accordance with the direction in which each component is described. Therefore, the words described in the disclosure are not limited thereto, and may be replaced as appropriate.

In this disclosure, the terms "mounted," "connected," and "connected" are to be construed broadly unless otherwise specifically stated or limited. For example, it may be a fixed connection, or a removable connection, or an integral connection; can be a mechanical connection, or an electrical connection; either directly or indirectly through intervening components, or both may be interconnected. The specific meaning of the above terms in the present disclosure can be understood by those of ordinary skill in the art as appropriate.

In the present disclosure, "parallel" means a state in which an angle formed by two straight lines is-10 ° or more and 10 ° or less, and therefore, includes a state in which the angle is-5 ° or more and 5 ° or less. The term "perpendicular" refers to a state in which the angle formed by two straight lines is 80 ° or more and 100 ° or less, and therefore includes a state in which the angle is 85 ° or more and 95 ° or less.

Based on the principle of reflection of light, an object can be imaged in a plane mirror. For the imaging of the object combined by the two plane mirrors, the number of the imaging can be changed according to the different positions of the object and the different angles between the two plane mirrors, and a symmetrical three-dimensional display effect can be formed.

The number of images formed by the combination of the two flat mirrors is illustrated in fig. 1. When the internal included angle of the two plane mirrors M1 and M2 is alpha, the common number of the object entity and the virtual image is 360 degrees/alpha. When the internal included angle between the two plane mirrors M1 and M2 is 60 °, virtual images of M1 and M2 are formed in the mirrors based on the imaging principle. When an object P is within the included angle of the two plane mirrors, virtual images P1, P2, P3, P4 and P5 of the object P are formed. The number of the object entities and the virtual images is 360/60 degrees or 6.

When the object P is close to the mirror surface on one side, the position of the virtual image is also moved correspondingly according to the mirror axis symmetry principle. When the object P is positioned on the surface of the mirror, the virtual images which are originally close to each other are superposed, so that when the object P is positioned on the surface of the mirror, the number of the images formed by the entity and the virtual images is 360 degrees/alpha/2.

When the object P is on the surface of one of the two flat mirrors, an axisymmetric pattern appears as the angle between the two flat mirrors is adjusted within a certain range. When a plurality of imaging objects are distributed on the surface of a certain mirror, the pattern presents a three-dimensional feeling due to the fact that the distance between the plurality of objects and the junction of the two mirrors, namely the distance between the two symmetrical axes, is different. Accordingly, a three-dimensional figure can be designed according to this manner.

When the included angle between the two plane mirrors M1 and M2 is 90 °, the number of images formed by the solid and virtual images is 2, and a stereoscopic image can be set according to the method.

When the included angle between the two plane mirrors M1 and M2 is 90 °, a reflective area and a non-reflective area may be provided on the mirror surface, and only the reflective area may form a mirror-symmetric pattern according to the mirror-symmetric property. As shown in fig. 2, fig. 2 has a solid 1 and a corresponding virtual image 1. Because the pattern formed by mirror symmetry has equidistant symmetry properties. Therefore, when the included angle between the two mirror surfaces is 90 °, the entity 1 and the virtual image 1 can form a pattern a, that is, the pattern a can be determined first during design, the pattern a is divided axisymmetrically, half of the divided pattern is placed on the surface of the mirror body M1, and a reflection region is arranged in a corresponding region (axisymmetric region) of the other mirror body M2.

In order to achieve the stereoscopic effect, a pattern B may be disposed on the other mirror M2, and the pattern B may be disposed with or without a reflective region at a position corresponding to the mirror M1 as required. The graphic B may have the effect of being spatially placed on the overall graphic a (e.g. the overall graphic a formed by the solid 1 and the virtual image 1 is a island and the graphic B is the sun suspended in the sky), as shown in fig. 3.

In the embodiment of the disclosure, the switching between the display state and the mirror state can be realized by liquid crystal dimming, and the mirror interaction is realized by using double screens.

As shown in fig. 4, the embodiment of the present disclosure provides a display device, which may have two display areas, a first display area 100 and a second display area 200, wherein at least one of the first display area 100 and the second display area 200 includes at least one sub-area, the sub-area may be switched between a display state and a mirror state, and an included angle between the first display area 100 and the second display area 200 is variable.

According to the scheme provided by the embodiment, when the sub-area is in the mirror surface state, the display content of another display area can be imaged to form display information including an entity and a virtual image, and the display information can be changed along with the change of the included angle between the first display area 100 and the second display area 200 (the included angle between the mirror surface and the entity is changed, and the position of the virtual image can be correspondingly changed), so that an interactive display effect is realized. The scheme that this embodiment provided carries out the mirror surface interactive for using paper, and interactive effect can dynamic adjustment, can provide multiple interactive content, need not to use the camera, has privacy protection's effect.

The display state refers to normal display of the display area, and the mirror state refers to the display area presenting a mirror.

In an exemplary embodiment, the first display area 100 and the second display area 200 may be switched between a display state and a mirror state. That is, all of the first display area 100 and the second display area 200 can be switched between the display state and the mirror state. However, the embodiments of the present disclosure are not limited thereto, and only one display region may be switchable between a display state and a mirror state, and the other display region may only support the display state.

In an exemplary embodiment, the display device includes a first display module and a second display module, a display area of the first display module is the first display area 100, and a display area of the second display module is the second display area 200; or, first display area 100 with second display area 200 is the different display area of same display module assembly, can use the different display area of same display screen, realizes the mirror surface interdynamic through buckling the display screen, perhaps, can use two independent display screens to realize the mirror surface interdynamic. The scheme provided by the embodiment of the disclosure can be applied to display equipment with mirror display, which can adjust the angle between two screens such as two separate screens, a folding screen (the folding screen can be two screens, or one screen is folded), a double-screen notebook and the like.

As shown in fig. 5, in an exemplary embodiment, the display module may include: the display screen comprises a display screen module 10 and a mirror switching screen 20, wherein the mirror switching screen 20 can switch a transmission mode and a reflection mode in a display area.

In an exemplary embodiment, the display module 10 may be a self-luminous display module, such as an OLED display module, or a liquid crystal display module. At this time, the display module may further include a backlight module 30, and the backlight module 30 is disposed on a side of the display screen module 10 away from the mirror switching screen 20.

In an exemplary embodiment, as shown in fig. 6, the mirror switching screen 20 may include: a transflective film 21, a polarizer 27, an electrode structure and a liquid crystal layer 24 disposed between the polarizer 27 and the transflective film 21; the display screen module 10 may be located on a side of the transflective film 21 away from the liquid crystal layer 24, and a light-emitting surface of the display screen module 10 faces the transflective film 21, wherein the electrode structure is configured to control liquid crystal molecule deflection in the liquid crystal layer 24; when the liquid crystal layer 24 is in the first state, the light incident from the polarizer 27 may pass through the transflective film 21; when the liquid crystal layer 24 is in the second state, light incident from the polarizer 27 is reflected by the transflective film 21.

In an exemplary embodiment, when the liquid crystal layer 24 is not energized, since the liquid crystal has refractive index anisotropy, the polarization plane is twisted with the twist of the liquid crystal molecules when light passes through the liquid crystal layer 24, and the polarization plane is rotated by 90 ° when light exits the liquid crystal layer 24. When the liquid crystal layer 24 is energized, the plane of polarization is unchanged as light passes through the liquid crystal layer 24.

In the mirror switching screen 20, when the electrode structure controls the liquid crystal layer 24 to be in the first state, the light (light in the direction a) incident from the polarizer 27 may penetrate through the transflective film 21 and be absorbed by an object on a side of the transflective film 21 away from the liquid crystal layer 24, for example, the light may be absorbed by the display screen module 10, when the display screen module 10 is placed on a side of the transflective film 21 away from the liquid crystal layer 24 and the light-emitting surface faces the transflective film 21, the light (light in the direction B) emitted from the display screen module 10 may sequentially penetrate through the transflective film 21, the liquid crystal layer 24 and the polarizer 21 to be incident to the eyes of a user, at this time, the mirror switching screen 20 does not reflect light, and the user may observe the picture displayed by the display screen module 10, as shown in fig. 7; when the electrode structure controls the liquid crystal layer 24 to be in the second state, the light incident from the polarizer 27 (light incident in the direction a) is reflected by the transflective film 21 to the eyes of the user, and the mirror switching panel 20 now has a mirror function for the user, as shown in fig. 8.

In an exemplary embodiment, the mirror switching screen 20 may further include: a first transparent substrate 22 positioned between the liquid crystal layer 24 and the transflective film 21; and a second transparent substrate 26 positioned between the liquid crystal layer 24 and the polarizer 27.

In an exemplary embodiment, at least one of the first transparent substrate 22 and the second transparent substrate 26 may have touch lines distributed thereon, and the touch screen 20 may be used to control the display device.

In an exemplary embodiment, the first transparent substrate 22 and the second transparent substrate 26 may be glass substrates or other transparent material substrates having a bearing function.

The positional relationship between the transmission axis of polarizer 27 and the transmission axis of transflective film 21 may be various, for example, in the embodiment shown in fig. 7 and 8, the transmission axis of polarizer 27 and the transmission axis of transflective film 21 may be perpendicular. For example, the transmission axis of the polarizer 27 may be 0 °, and the transmission axis of the transflective film 21 may be 90 °. When the electrode structure is not energized, as shown in fig. 7, the light incident in the direction a passes through the polarizer 27 with a transmission axis of 0 °, the natural light becomes 0 ° polarized light, and enters the liquid crystal layer 24, and due to the deflection of the liquid crystal layer 24, the 0 ° polarized light becomes 90 ° polarized light, and can pass through the transflective film 21 with a transmission axis of 90 °, and irradiate onto the display module 10 (for example, a circuit board or a substrate of the display module 10). When natural light or polarized light (for example, light emitted from the display screen module 10) in the direction B passes through the

transflective film

21, 0 ° polarized light is reflected to the environment, 90 ° polarized light enters the liquid crystal layer 24, the liquid crystal layer 24 controls light deflection, and the 90 ° polarized light is changed into 0 ° polarized light, so that the 0 ° polarized light can be transmitted to the outside (the side away from the liquid crystal layer 24) through the 0 ° polarizer 27.

When the electrode structure is energized, as shown in fig. 8, the liquid crystal molecules in the liquid crystal layer 24 do not deflect the incident light, and the natural light in the direction a irradiates the polarizer 27, a 0 ° polarized light is generated and enters the liquid crystal layer 24, and the liquid crystal molecules in the liquid crystal layer 24 do not substantially deflect the optical axis of the light, i.e., the light emitted from the liquid crystal layer 24 is regarded as the 0 ° polarized light, and after the 0 ° polarized light reaches the transflective film 21, the optical axis is perpendicular to the optical axis of the transflective film 21 (the transmission axis is 90 °), and cannot transmit but is reflected by the transflective film 21, and at this time, the light is still 0 ° polarized light, so that the light can also pass through the liquid crystal layer 24 and the polarizer 27 and emit to the environment to form a mirror image. The light from the B direction passes through the transflective film 21 having a transmission axis of 90 ° to become 90 ° polarized light, and the 90 ° polarized light passes through the liquid crystal layer 24, remains as 90 ° polarized light, and is then absorbed by the polarizer 27 having a transmission axis of 0 °. Since the mirror switching screen 20 mainly reflects light and is almost opaque, the mirror mode of the mirror switching screen 20 may be referred to as a mirror state of the display device for the entire display device, and the display screen module 10 may not emit light or display black in the mirror state.

In the above embodiments, the transmission axis of the polarizer 27 and the transmission axis of the transflective film 21 are perpendicular to each other only as an example, and the embodiments of the present disclosure are not limited thereto.

For example, the transmission axis of the polarizer 27 may be parallel to the transmission axis of the transflective film 21. Then when the electrode structure is turned off, that is, when the liquid crystal layer 24 is not energized, after the light passes through the polarizer 27, the optical axis of the light is parallel to the optical axis of the transflective film 21 (because the transmission axis of the polarizer 27 may also be parallel to the transmission axis of the transflective film 21), but during the process that the light passes through the liquid crystal layer 24 and is transmitted to the transflective film 21, the optical axis is deflected by 90 degrees by the liquid crystal molecules of the liquid crystal layer 24, is perpendicular to the transmission axis of the transflective film 21, cannot pass through the transflective film 21, and is reflected, which is called the mirror mode of the mirror switching screen 20, and for the whole display device, it can be called the mirror state of the display device.

When the electrode structure is powered up, the optical axis of the light emitted by the polarizer 27 is parallel to the transmission axis of the transflective film 21, the light is hardly deflected in the process of entering the transflective film 21 through the liquid crystal layer 24, and the optical axis is still parallel to the transmission axis of the transflective film 21, so that the light is absorbed by the display screen module 10, and the light emitted by the display screen module 10 can sequentially pass through the transflective film 21, the liquid crystal layer 24 and the polarizer 27 to be emitted, because the mirror face switching screen 20 mainly embodies the light transmission function at the moment, the light is hardly reflected, which is called as the transmission mode of the mirror face switching screen 20, and for the whole display device, which can be called as the display state of the display device.

In an exemplary embodiment, the liquid crystal layer 24 may deflect incident light when the liquid crystal layer 24 is energized, and the liquid crystal layer 24 may not deflect incident light when the liquid crystal layer 24 is not energized.

In an exemplary embodiment, as shown in fig. 6, the electrode structure may include a first electrode 23 and a second electrode 25 distributed on two sides of the liquid crystal layer 24, wherein the first electrode 23 may be disposed on a side of the first transparent substrate 22 close to the liquid crystal layer 24, the second electrode 25 may be disposed on a side of the second transparent substrate 26 close to the liquid crystal layer 24, and an electric field may be formed between the first electrode 23 and the second electrode 25.

In an exemplary embodiment, the electrode structure may be distributed on the same side of the liquid crystal layer 24, for example, the electrode structure may include a plurality of electrode blocks disposed at intervals, a potential difference exists between adjacent electrode blocks, and an electric field is formed between adjacent electrode blocks, and the electrode structure may specifically be disposed on a side of the first transparent substrate 22 close to the liquid crystal layer 24, or on a side of the second transparent substrate 26 close to the liquid crystal layer 24.

In an exemplary embodiment, the display panel module 10 may include an upper polarizer, the transmission axis of the upper polarizer of the display panel module 10 may be 90 °, and the upper polarizer may be adjacent to the transflective film 21. When the display module 10 is a liquid crystal display, the display module may further include a lower polarizer and an upper polarizer, which are respectively located at two sides of the liquid crystal layer of the display module 10, and a transmission axis of the lower polarizer may be 0 °. Here, the light transmission axis of the display module 10 may be at other angles, which is only an example.

The display module can be divided into a full mirror mode, a common display mode and a partial area mirror mode. In the full mirror mode, the first display area 100 and the second display area 200 are in a mirror state and can be used as a normal mirror, and in the normal display mode, the first display area 100 and the second display area 200 are displayed normally and are consistent with a normal display. In the partial mirror mode, the display area of the display device can partially present a display state, and partially present a mirror state, so that mirror three-dimensional interaction can be realized. The display device can be switched among a full mirror mode, a common display mode and a partial mirror mode, and the switching method comprises but is not limited to key switching, touch screen switching, remote control instruction switching and the like.

In an exemplary embodiment, the display apparatus may further include a processor configured to:

In an exemplary embodiment, the transmitter and the receiver may be infrared sensors, but are not limited thereto, for example, when a direction sensor is configured in the display device, the included angle may be calculated according to parameters of the direction sensor, and the like.

In an exemplary embodiment, the display device may further include other modules, such as one or a combination of a power supply, a control module, a storage module, a sound module, and the like.
