Detailed Implementation

[0054] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0055] like Figure 1 As shown, Figure 1 A schematic diagram of the structure of a display device according to an embodiment of this application is shown. Figure 2 A schematic diagram showing the structure of the switching component of a display device according to an embodiment of the present application in a second state is provided. Figure 3A schematic diagram showing the structure of the switching component of the display device according to another embodiment of this application in a second state is shown. Figure 4 A schematic diagram showing the structure of the switching component of the display device according to another embodiment of this application in a second state is shown.

[0056] like Figure 1-4 As shown, one aspect of this application provides a display device, which includes:

[0057] A pixel display area 100 has a plurality of first sub-pixels 110 and a plurality of second sub-pixels 120 arranged in a plurality of sorted configurations, wherein each first sub-pixel 110 and its corresponding second sub-pixel 120 are arranged adjacent to each other; and

[0058] The conversion component 200 is disposed on the pixel display area 100;

[0059] The conversion component 200 has a first state and a second state. In the first state, the conversion component 200 is transparent so that light can pass through it. In the second state, the conversion component 200 is opaque and set at a specified angle so that the light from each first sub-pixel 110 and the light from each second sub-pixel 120 are reflected to the corresponding area at different angles.

[0060] In this embodiment, the display device can be a central control display screen of an in-vehicle device, or a display screen in other scenarios. The pixel display layer is disposed on the display panel of the display screen, and the pixel display area 100 is part or all of the pixel display layer, in which a plurality of sub-pixels are arranged. These sub-pixels can be red sub-pixels, green sub-pixels, and blue sub-pixels. In this embodiment, the sub-pixels are not distinguished as red, green, and blue sub-pixels; instead, the pixel display area 100 is determined based on the arrangement of the sub-pixels.

[0061] For a pixel display area 100 containing several arranged sub-pixels, the sub-pixels of the pixel display area 100 are divided into first sub-pixels 110 and second sub-pixels 120. The method for determining the first sub-pixels 110 and second sub-pixels 120 is that each first sub-pixel 110 and at least one corresponding second sub-pixel 120 are set as adjacent. If the first sub-pixel of the pixel display area 100 is the first sub-pixel 110, then the second sub-pixel of the pixel display area 100 is the second sub-pixel 120. That is, sub-pixels with odd numbers are all first sub-pixels 110, and sub-pixels with even numbers are all second sub-pixels 120. Of course, the arrangement can also be reversed, that is, sub-pixels with even numbers are first sub-pixels 110, and sub-pixels with odd numbers are second sub-pixels 120. Each first sub-pixel 110 and each second sub-pixel 120 can output the same image signal, or they can output different image signals depending on the switching transistor of the driving circuit or the driving of different driving pixel circuits.

[0062] In this embodiment, the conversion component 200 has a first state and a second state, which can be switched according to actual conditions. For example, the conversion component 200 can be composed of magnetic particles, such as magnetic nanoparticles. The magnetic particles are nanoparticle materials, such as nano-iron-cobalt alloy dispersed in an aluminum fluoride medium. This structure can simultaneously utilize the strong magnetic properties of the iron-cobalt alloy and the light transmittance of aluminum fluoride. In the normal display state, the non-magnetic field state, the nanoparticles are transparent, which realizes the first state of the conversion component 200. In the dual-view display state, the magnetic field state, the nanoparticles are opaque. Because they contain metal particles, they have a certain degree of reflectivity, which realizes the second state of the conversion component 200. The nanoparticle material is made of a mixture of nano-scale magnetic metal particles (iron-cobalt alloy) and insulating material (aluminum fluoride). Dispersing the nano-iron-cobalt alloy in an aluminum fluoride medium allows the simultaneous utilization of the strong magnetic properties of the iron-cobalt alloy and the light transmittance of aluminum fluoride, exhibiting high light transmittance and strong magnetism at room temperature. The transparency of the material can be controlled by a magnetic field, which is also a novel magneto-optical effect.

[0063] Through the first and second states of the conversion component 200, in the first state, the conversion component 200 is transparent so that light can pass through it. In the first state, the driving circuit controls the first sub-pixel 110 and the second sub-pixel 120 to output the same image signal. The light from each of the first sub-pixels 110 and each of the second sub-pixels 120 can pass through the conversion component 200 and reach the viewer's eye, thereby allowing the viewer to see an image signal output from the front. In the second state, the magnetic particles of the conversion component 200 change their arrangement to become opaque and tilted to a specified angle, making the conversion component 200 reflective. The driving circuit controls each first sub-pixel 110 and each second sub-pixel 120 to output different image signals. For example, the driving circuit controls each first sub-pixel 110 to output a first image signal, and the driving circuit controls each second sub-pixel 120 to output a second sub-pixel 120 image. The switching transistor of the driving circuit controls the first sub-pixel 110 to light up in the first frame and the second sub-pixel 120 to not light up in the first frame; the first sub-pixel 110 to not light up in the second frame and the second sub-pixel 120 to light up in the second frame. Alternatively, two sets of pixel circuits can be used to realize that the first sub-pixel 110 and the second sub-pixel 120 are displayed separately without interfering with each other, thus meeting the dual-view requirement. The second-state conversion unit 200 can reflect the light output by each first sub-pixel 110 to a first designated area, so that a person in the first designated area can observe the first image displayed by each first sub-pixel. The second-state conversion unit 200 can also reflect the light output by each second sub-pixel 120 to a second designated area, so that a person in the second designated area can see the second image output by each second sub-pixel 120.

[0064] For example, when the vehicle is in motion, the passenger can enjoy entertainment through the first image output by each first sub-pixel 110 displayed on the central control screen. For driving safety, the driver needs to switch to navigation reminders that are conducive to driving safety. That is, the driver can view the navigation images displayed by each second sub-pixel 120 on the central control screen, thereby enabling safe driving.

[0065] The display device of this embodiment can truly achieve a dual-view effect. It can achieve both normal display and dual-view functionality using a single display device.

[0066] In this embodiment, the display device includes a pixel display area 100 and a conversion component 200 disposed on the pixel display area 100. The pixel display area 100 has a plurality of first sub-pixels 110 and a plurality of second sub-pixels 120 arranged in a plurality of configurations. Each first sub-pixel 110 and its corresponding second sub-pixel 120 are arranged adjacent to each other. Each first sub-pixel 110 and each second sub-pixel 120 can output the same image signal or output different image signals. The conversion component 200 has a first state and a second state. When the conversion component 200 is in the first state, it is transparent, i.e., it has high light transmittance. By controlling each first sub-pixel 110 and each second sub-pixel 120 to output the same image signal, only one display image is displayed on the display device, which is convenient for multiple people to watch and discuss the same video together. When the conversion component 200 is in its second state, it is opaque and set at a specified angle, meaning its light transmittance is reduced and its reflectivity is enhanced. At this angle, each first sub-pixel 110 and each second sub-pixel 120 outputs different image signals. The light output by each first sub-pixel 110 is reflected by the conversion component 200 to the first corresponding area, allowing a person in that area to see the first image output by the first sub-pixel 110. Similarly, the light output by each second sub-pixel 120 is reflected by the conversion component 200 to the second corresponding area, allowing a person in that area to see the second image output by the second sub-pixel 120. This allows a single display device to output two different images to viewers in corresponding areas, providing a better viewing experience. Viewers can freely adjust the image to their liking, enabling a single display device to truly achieve dual-view and normal display without interference between them, resulting in a superior display effect.

[0067] like Figure 5 As shown, Figure 5 A schematic diagram of the structure of a switching component of a display device according to another embodiment of this application is shown.

[0068] In one embodiment, the conversion component 200 includes:

[0069] Multiple first conversion elements 210 are arranged on the pixel display area 100;

[0070] Multiple second conversion elements 220 are arranged on the side of the first conversion element 210 away from the pixel display area 100;

[0071] The first converter 210 and the second converter 220 both have a first state and a second state. When both the first converter 210 and the second converter 220 are in the second state, the first converter 210 is at a first specified angle and the second converter 220 is at a second specified angle. The first specified angle and the second specified angle are different angles.

[0072] In this embodiment, there are multiple first converters 210 and second converters 220. Each first converter 210 can be configured corresponding to a first sub-pixel 110, and each second converter 220 can be configured corresponding to a second sub-pixel 120. When both the first converters 210 and 220 are in a first state, the driving circuit controls the first sub-pixel 110 and the second sub-pixel 120 to output the same image signal. Light from the first sub-pixel 110 and the second sub-pixel 120 can pass through the transparent first converters 210 and 220 and reach the viewer's eye, allowing the viewer to see an image signal output from the front. In a second state, the magnetic particles of the first converters 210 and 220 change their arrangement, becoming opaque and tilted to a specified angle. The first converter 210 is at a first specified angle, and the second converter 220 is at a second specified angle; the first and second specified angles are different angles. The first converters 210 and 220 can reflect corresponding light into corresponding areas based on different specified angles. At this time, the driving circuit controls the first sub-pixel 110 and the second sub-pixel 120 to output different image signals. For example, the driving circuit controls the first sub-pixel 110 to output a first image signal, and the driving circuit controls the second sub-pixel 120 to output a second sub-pixel 120 image. The first sub-pixel 110 is lit in the first frame, and the second sub-pixel 120 is not lit in the first frame; the first sub-pixel 110 is not lit in the second frame, and the second sub-pixel 120 is lit in the second frame. Alternatively, two sets of pixel circuits can be used to achieve separate display of the first sub-pixel 110 and the second sub-pixel 120 without interference, thus meeting the dual-view requirement. In the second state, the first conversion element 210, set at a first angle, can reflect the light output by the first sub-pixel 110 to a first designated area, allowing a person in the first designated area to observe the first image displayed by the first pixel. In the second state, the second conversion element 220, set at a second designated angle, can reflect the light output by the second sub-pixel 120 to a second designated area, allowing a person in the second designated area to see the second image output by the second sub-pixel 120.

[0073] In this embodiment, the first conversion element 210 can correspond to a portion of the first sub-pixel 110, and the second conversion element 220 can correspond to a portion of the second sub-pixel 120. Similarly, the first conversion element 210 can correspond to a portion of the second sub-pixel 120, and the second conversion element 220 can correspond to a portion of the first sub-pixel 110. Both the first conversion element 210 and the second conversion element 220 are composed of magnetic particles, such as magnetic nanoparticles. These magnetic particles are nanoparticle materials, such as nano-iron-cobalt alloy dispersed in an aluminum fluoride medium. This structure can simultaneously utilize the strong magnetism of the iron-cobalt alloy and the light transmittance of aluminum fluoride. In normal display mode, in a non-magnetic field state, the nanoparticles are transparent, thus achieving the first state of the first conversion element 210 and the second conversion element 220. In dual-view display mode, in a magnetic field state, the nanoparticles are opaque. Because they contain metal particles, they have a certain degree of reflectivity, thus achieving the second state of the first conversion element 210 and the second conversion element 220.

[0074] In this embodiment, since the first conversion element 210 and the second conversion element 220 are considered to have the same specified angle in the second state, the first conversion element 210 and the second conversion element 220 cannot be placed on the same layer. The first conversion element 210 and the second conversion element 220 can have the same shape or different shapes. The second conversion element 220 is arranged on the side of the first conversion element 210 away from the pixel display area 100, so that the first conversion element 210 and the second conversion element 220 are arranged in layers. Under the action of corresponding magnetic fields, the first conversion element 210 can be set at a first specified angle, and the second conversion element 220 can be set at a second specified angle. This avoids the problem of magnetic field interference between the first conversion element 210 and the second conversion element 220, thereby effectively controlling the reflection angles of the first conversion element 210 and the second conversion element 220 respectively. This ensures that the light from the first sub-pixel 110 is reflected to the first specified area through the first specified angle of the first conversion element 210, and the light from the second sub-pixel 120 is reflected to the corresponding second specified area through the second specified angle of the second conversion element 220.

[0075] like Figure 5 As shown, in one embodiment, the display device further includes:

[0076] The first control unit 310 is disposed on either side of the first conversion member 210 and is used to generate a first magnetic field so that the first conversion member 210 is in a second state.

[0077] The second control unit 320 is disposed on either side of the second conversion member 220 and is used to generate a second magnetic field so that the second conversion member 220 is in a second state.

[0078] Both the first control unit 310 and the second control unit 320 can be coils, permanent magnets, or other devices capable of generating magnetic fields. In this embodiment, the first control unit 310 and the second control unit 320 can be coils. By controlling the magnetic field strength generated by the coils, the reflectivity and reflection angle of the first conversion element 210 and the second conversion element 220 can be controlled. The coil material can be ITO, Cu, etc. Transparent materials, represented by ITO, can be designed on the entire top of the screen. Opaque materials, represented by Cu, can be placed on the top, bottom, left, and right edges. The coils simultaneously realize NFC functionality. In normal display mode, the coils have NFC functionality. In dual-view display mode, that is, when the coils are activated and generate a magnetic field, the NFC functionality of the coils is turned off.

[0079] In this embodiment, there can be one or more first control units 310. If there is only one first control unit 310, it can be disposed on one side of the side bezel of the display device. The first control unit 310 generates a first magnetic field. Under the action of the first magnetic field, the first conversion element 210 switches from a first state to a second state. That is, the first conversion element 210 switches from a first state with transparent magnetic particles to a second state with opacity and a first specified angle under the action of the magnetic field. There can also be multiple first control units 310, arranged above or below the first conversion element 210. Each first control unit 310 can correspond one-to-one with the first conversion element 210, or one first control unit 310 can correspond to two first conversion elements 210, etc., so as to accurately control the emissivity and consistency of the first specified angle of the first conversion element 210 in the second state, so that each first conversion element 210 can maintain good reflectivity and the same first specified angle, thereby ensuring that the light of each first sub-pixel 110 can be reflected into the first corresponding area through the corresponding first conversion element 210, so that people in the area can clearly see the video image.

[0080] In this embodiment, there may be one or more second control units 320. If there is only one second control unit 320, it can be disposed on the other side of the side bezel of the display device. In order to avoid conflict between the first magnetic field generated by the first control unit 310 and the second magnetic field generated by the second control unit 320, the first control unit 310 and the second control unit 320 can be disposed separately, that is, disposed on the left and right sides of the bezel respectively, thereby effectively reducing the mutual interference between the first magnetic field and the second magnetic field.

[0081] A second magnetic field is generated by the second control unit 320. Under the action of the second magnetic field, the first conversion element 210 switches from a first state to a second state. That is, the first conversion element 210 switches from a first state with transparent magnetic particle arrangement to a second state with opacity and a first specified angle under the action of the magnetic field. There can also be multiple second control units 320, arranged above or below the second conversion element 220. Each second control unit 320 can correspond one-to-one with the second conversion element 220, or one second control unit 320 can correspond to two second conversion elements 220, etc., so as to accurately control the emissivity and consistency of the second specified angle of the second conversion element 220 in the second state. This ensures that each second conversion element 220 can maintain good reflectivity and the same second specified angle, thereby ensuring that the light of each second sub-pixel 120 can be reflected by the corresponding second conversion element 220 into the second corresponding area, so that people in that area can clearly see the video image.

[0082] like Figure 5 As shown, in one embodiment, the display device further includes:

[0083] A dielectric shielding layer 250 is disposed between the first conversion element 210 and the second conversion element 220 to isolate the first magnetic field and the second magnetic field.

[0084] The dielectric shielding layer 250 is disposed between the first converter 210 and the second converter 220. The dielectric shielding layer 250 isolates the magnetic fields acting on the first converter 210 and the second converter 220, so that the first magnetic field only affects the first converter 210 and the second magnetic field only affects the second converter 220. This avoids the first magnetic field affecting the second converter 220 and causing the second specified angle of the second converter 220 to be not configured properly. Similarly, it avoids the second magnetic field affecting the first converter 210 and causing the first specified angle of the first converter 210 to be not configured properly.

[0085] like Figure 5 , Figure 8 and Figure 9 As shown, in one embodiment,

[0086] Multiple first control units 310 are arranged between the first conversion element 210 and the medium isolation layer;

[0087] Multiple second control units 320 are arranged between the second conversion element 220 and the medium isolation layer.

[0088] In this embodiment, there are multiple first control units 310 and second control units 320. Each first control unit 310 can correspond one-to-one with a first conversion element 210, or one first control unit 310 can correspond to two first conversion elements 210, etc. Similarly, each second control unit 320 can correspond one-to-one with a second conversion element 220, or one second control unit 320 can correspond to two second conversion elements 220, etc. Both the first control unit 310 and the second control unit 320 can be coils, permanent magnets, or other devices capable of generating magnetic fields. In this embodiment, both the first control unit 310 and the second control unit 320 can be coils. Since both the first control unit 310 and the second control unit 320 are located above the pixel display area 100, the display of both the first control unit 310 and the second control unit 320 can be made of transparent materials, such as transparent coils, which can be made of ITO material.

[0089] The first control unit 310 can be housed within a corresponding carrier, which can be made of transparent materials such as PET or PI, without affecting the light transmission of the first sub-pixel 110 and the second sub-pixel 120. By placing the first control unit 310 between the first converter 210 and the dielectric isolation layer, more precise control of the first converter 210 can be achieved. The first magnetic field generated by the first control unit 310 corresponds one-to-one with the magnetic particles of the first converter 210, ensuring that the magnetic particles of each first converter 210 are of the same size. This ensures that the light from each first sub-pixel 110 can be reflected through the corresponding first converter 210 into the first corresponding area, allowing people in that area to clearly view the video image.

[0090] The second control unit 320 can be housed within a corresponding carrier, which can be made of transparent materials such as PET or PI, without affecting the light transmission of the first sub-pixel 110 and the second sub-pixel 120. By placing the second control unit 320 between the second conversion element 220 and the dielectric isolation layer, more precise control of the second conversion element 220 can be achieved. The second magnetic field generated by the second control unit 320 corresponds one-to-one with the magnetic particles of the second conversion element 220, ensuring that the magnetic particles of each second conversion element 220 are of the same size. This ensures that the light from each second sub-pixel 120 can be reflected through the corresponding second conversion element 220 into the corresponding area, allowing people in that area to clearly view the video image.

[0091] In this embodiment, a first conversion element 210, a first control unit 310, a dielectric shielding layer 250, a second conversion element 220, and a second control unit 320 are sequentially externally attached to the prepared pixel display area 100. Specifically, the external attachment process can be achieved by nano-transfer printing.

[0092] like Figure 6 and Figure 7 As shown, in one embodiment, the display device further includes:

[0093] The first border area 130 is located on one side of the pixel display area 100, the first conversion element 210, and the second conversion element 220, and the first control unit 310 is disposed on the first border area 130.

[0094] The second border area 140 is located on the side of the pixel display area 100, the first conversion element 210 and the second conversion element 220 away from the first border area 130, and the second control unit 320 is disposed on the second border area 140.

[0095] In addition to the pixel display area 100, the display device also has bezel areas on the left and right sides of the pixel display area 100. For example, the left side of the pixel display area 100 is the first bezel area 130, and the right side is the second bezel area 140. By placing the first control unit 310 on the first bezel area 130 and the second control unit 320 on the second bezel area 140, the distance between the first control unit 310 and the second control unit 320 is relatively large. The first magnetic field generated by the first control unit 310 and the second magnetic field generated by the second control unit 320 are also relatively large, and the magnetic field weakens with distance. Therefore, the interference between the first magnetic field and the second magnetic field is reduced.

[0096] In some embodiments, to enable the first control unit 310 located in the first border area 130 and the second control unit 320 located in the second border area to control the first conversion element 210 and the second conversion element 220, the size of the first conversion element 210 can be gradually increased in the direction gradually moving away from the first control unit 310. That is, the size of the magnetic particles is largest at the position away from the first control unit 310 and smallest at the position close to the first control unit 310. This ensures that under the action of the first control unit 310, each first conversion element 210 can undergo equal or small-error deflection under the action of the first magnetic field of the first control unit 310, thereby ensuring that the light of the first sub-pixel 110 can be reflected to the corresponding first designated area through the corresponding first conversion element 210, so that a person in the first designated area can view the corresponding first image. Similarly, the size of the second conversion element 220 can be gradually increased in the direction gradually moving away from the second control unit 320. That is, the size of the magnetic particles is largest at the position away from the second control unit 320 and smallest at the position close to the second control unit 320. This method ensures that, under the action of the second control unit 320, each second conversion element 220 undergoes the same or small-error deflection under the action of the second magnetic field of the second control unit 320, thereby ensuring that the light of the second sub-pixel 120 can be reflected to the corresponding second designated area through the corresponding second conversion element 220, so that a person in the second designated area can view the corresponding second image.

[0097] In one embodiment, the display device further includes:

[0098] The driving circuit is electrically connected to the first sub-pixel 110 and the second sub-pixel 120. The driving circuit has a switching transistor, which is used to control the first sub-pixel 110 and the second sub-pixel 120 to light up respectively.

[0099] In the embodiments of this application, under normal display conditions, the first sub-pixel 110 and the second sub-pixel 120 output the same image, and the switching transistor of the driving circuit does not need to operate. When dual-view functionality is required, the switching transistor of the driving circuit illuminates the first sub-pixel 110 and the second sub-pixel 120 separately. For example, the driving circuit controls the first sub-pixel 110 to output a first image signal, and the driving circuit controls the second sub-pixel 120 to output a second sub-pixel 120 image. The first sub-pixel 110 is illuminated in the first frame, and the second sub-pixel 120 is not illuminated in the first frame; the first sub-pixel 110 is not illuminated in the second frame, and the second sub-pixel 120 is illuminated in the second frame, etc. This allows for the control of outputting different images to the first sub-pixel 110 and the second sub-pixel 120, achieving dual-view image output. This ensures that a viewer in a first designated area can clearly see the first image output by the first sub-pixel 110, and a viewer in a second designated area can clearly see the second image output by the second sub-pixel 120.

[0100] In one embodiment, the display device further includes:

[0101] The first pixel circuit is electrically connected to the first sub-pixel 110 and is used to control the first sub-pixel 110 to output a first signal.

[0102] The second pixel circuit is electrically connected to the second sub-pixel 120 and is used to control the second sub-pixel 120 to output a second signal.

[0103] In the embodiments of this application, under normal display conditions, the first sub-pixel 110 and the second sub-pixel 120 output the same image, and the first pixel circuit and the second pixel circuit output the same image signal, so that the viewer can view the image displayed by the display device from the front.

[0104] In dual-view mode, the first pixel circuit controls the first sub-pixel 110 to output a first image signal, enabling a viewer in the first designated area to clearly see the first image output by the first sub-pixel 110. The second pixel circuit controls the second sub-pixel 120 to output a second image, enabling a viewer in the second designated area to clearly see the second image output by the second sub-pixel 120. By driving the corresponding first sub-pixel 110 and second sub-pixel 120 respectively through the first pixel circuit and the second pixel circuit, the image signals of the first sub-pixel 110 and the second sub-pixel 120 can be easily controlled, thereby ensuring that the display of the first sub-pixel 110 and the display of the second sub-pixel 120 do not interfere with each other, achieving a better dual-view effect.

[0105] In one embodiment, the display device further includes:

[0106] Multiple black bodies 400 are disposed between the conversion unit 200 and the pixel display area 100, and are respectively located above the adjacent first sub-pixel 110 and second sub-pixel 120.

[0107] In this embodiment, the blackbody 400 is made of a light-shielding black material, which can be a BM material with high light absorption or other materials with high light absorption, without limitation; the position of the blackbody 400 can be set on the package, or made on the same layer as the BM of the COE or on a different layer, or it can be made on the FMLOC touch screen, etc.

[0108] The blackbody 400 in this embodiment can absorb the light emitted by the first sub-pixel 110 and the second sub-pixel 120, thereby limiting the output viewing angle of the light from the first sub-pixel 110 and the second sub-pixel 120 and avoiding crosstalk between the first sub-pixel 110 and the second sub-pixel 120 in the case of dual view.

[0109] There are multiple black bodies 400. One or more black bodies 400 can be set at corresponding positions adjacent to each first sub-pixel 110 and second sub-pixel 120. The black bodies 400 are set between the conversion unit 200 and the pixel display area 100, so that the light output from the first sub-pixel 110 and the second sub-pixel 120 between the first sub-pixel 110 and the second sub-pixel 120 can be absorbed by the black bodies 400, thereby achieving the purpose of limiting the output viewing angle of the light from the first sub-pixel 110 and the second sub-pixel 120.

[0110] In one embodiment, the conversion component 200 further includes:

[0111] The first carrier 230 is arranged on the pixel display area 100, and each first conversion element 210 is disposed on the first carrier 230;

[0112] The second carrier 240 is arranged on the side of the first conversion element 210 away from the pixel display area 100, and each second conversion element 220 is disposed on the second carrier 240.

[0113] In this embodiment, both the first carrier 230 and the second carrier 240 can be made of PET or PI material and are transparent. The first conversion member 210 is disposed on the first carrier 230, specifically within the first carrier 230. The first carrier 230 supports and fixes the first conversion member 210, and the structure of the forming layer can be disposed on the pixel display area 100. The second conversion member 220 is disposed on the first carrier 230, specifically within the second carrier 240. The second carrier 240 supports and fixes the second conversion member 220, and the structure of the forming layer can be disposed on the pixel display area 100.

[0114] Multiple first conversion elements 210 are arranged on a first carrier 230, which is disposed on the pixel display area 100. Light emitted from each first sub-pixel 110 can pass through the first carrier 230 and illuminate the corresponding first conversion element 210. Multiple second conversion elements 220 are arranged on a second carrier 240, which is disposed on the pixel display area 100. Light emitted from each second sub-pixel 120 can pass through the second carrier 240 and illuminate the corresponding second conversion element 220.

[0115] When both the first converter 210 and the second converter 220 are in the first state, the light output from each first sub-pixel 110 and each second sub-pixel 120 can pass through the corresponding first converter 210, dielectric shielding layer 250, second carrier 240, and second converter 220 and be output to the observer's eye. Alternatively, the light output from each first sub-pixel 110 and each second sub-pixel 120 can pass through the corresponding first converter 210, first control unit 310, dielectric shielding layer 250, second carrier 240, second converter 220, and second control unit 320 and be output to the observer's eye.

[0116] When the first conversion element 210 is in the second state, the light emitted by each first sub-pixel 110 can pass through the corresponding first conversion element 210, be reflected by the first deflector 210 and emitted at a predetermined angle, and then pass through the dielectric shielding layer 250 and the second carrier 240 before being emitted into the eye of an observer in the first designated area. Alternatively, the light emitted by each first sub-pixel 110 can pass through the corresponding first conversion element 210, be reflected by the first deflector 210 and emitted at a predetermined angle, and then pass through the first control unit 310, the dielectric shielding layer 250, the second carrier 240 and the second control unit 320 before being emitted into the eye of an observer.

[0117] When the second conversion element 220 is in the second state, the light emitted by each second sub-pixel 120 passes through the first carrier 230 and the dielectric shielding layer 250 and then illuminates the corresponding second conversion element 220. Reflected by the corresponding second deflector 220, the light is emitted at a predetermined angle and delivered to the observer's eye in the first designated area. Alternatively, the light emitted by each second sub-pixel 120 passes through the first carrier 230, the first control unit 210, and the dielectric shielding layer 250 and then illuminates the corresponding second conversion element 220. Reflected by the second deflector 220, the light is emitted at a predetermined angle and delivered to the observer's eye via the second control unit 320.

[0118] like Figure 10 As shown, Figure 10A flowchart illustrating a method for manufacturing a display device according to another embodiment of this application is provided. As another aspect of this application, this application provides a method for manufacturing a display device, the method comprising:

[0119] S110: Prepare a pixel display area 100. The pixel display area 100 has a plurality of first sub-pixels 110 and a plurality of second sub-pixels 120 arranged in a row. Each first sub-pixel 110 and its corresponding second sub-pixel 120 are arranged adjacent to each other.

[0120] S120: A conversion component 200 is prepared on the pixel display area 100. The conversion component 200 has a first state and a second state. In the first state, the conversion component 200 is transparent so that light can pass through the conversion component 200. In the second state, the conversion component 200 is opaque and set at a specified angle so that the light from the first sub-pixel 110 and the light from the second sub-pixel 120 are reflected to the corresponding areas at different angles.

[0121] The display device of the above embodiment can be prepared by the preparation method of the display device in this embodiment. The preparation of the conversion component 200 on the pixel display area 100 can be achieved by nano-transfer printing.

[0122] In this embodiment, the display device can be a central control display screen of an in-vehicle device, or a display screen in other scenarios. The pixel display layer is disposed on the display panel of the display screen, and the pixel display area 100 is part or all of the pixel display layer, in which a plurality of sub-pixels are arranged. These sub-pixels can be red sub-pixels, green sub-pixels, and blue sub-pixels. In this embodiment, the sub-pixels are not distinguished as red, green, and blue sub-pixels; instead, the pixel display area 100 is determined based on the arrangement of the sub-pixels.

[0123] For a pixel display area 100 containing several arranged sub-pixels, the sub-pixels of the pixel display area 100 are divided into a first sub-pixel 110 and a second sub-pixel 120. The first sub-pixel 110 and the second sub-pixel 120 are determined by setting them adjacent to each other. If the first sub-pixel of the pixel display area 100 is the first sub-pixel 110, then the second sub-pixel of the pixel display area 100 is the second sub-pixel 120. That is, sub-pixels with odd numbers are all first sub-pixels 110, and sub-pixels with even numbers are all second sub-pixels 120. Of course, they can also be arranged in reverse, that is, sub-pixels with even numbers are first sub-pixels 110, and sub-pixels with odd numbers are second sub-pixels 120. The first sub-pixel 110 and the second sub-pixel 120 can output the same image signal, or they can output different image signals depending on the switching transistor of the driving circuit or the driving of different driving pixel circuits.

[0124] In this embodiment, the conversion component 200 has a first state and a second state, which can be switched according to actual conditions. For example, the conversion component 200 can be composed of magnetic particles, such as magnetic nanoparticles. The magnetic particles are nanoparticle materials, such as nano-iron-cobalt alloy dispersed in an aluminum fluoride medium. This structure can simultaneously utilize the strong magnetic properties of the iron-cobalt alloy and the light transmittance of aluminum fluoride. In the normal display state, the non-magnetic field state, the nanoparticles are transparent, which realizes the first state of the conversion component 200. In the dual-view display state, the magnetic field state, the nanoparticles are opaque. Because they contain metal particles, they have a certain degree of reflectivity, which realizes the second state of the conversion component 200. The nanoparticle material is made of a mixture of nano-scale magnetic metal particles (iron-cobalt alloy) and insulating material (aluminum fluoride). Dispersing the nano-iron-cobalt alloy in an aluminum fluoride medium allows the simultaneous utilization of the strong magnetic properties of the iron-cobalt alloy and the light transmittance of aluminum fluoride, exhibiting high light transmittance and strong magnetism at room temperature. The transparency of the material can be controlled by a magnetic field, which is also a novel magneto-optical effect.

[0125] Through the first and second states of the conversion component 200, in the first state, the conversion component 200 is transparent so that light can pass through it. In the first state, the driving circuit controls the first sub-pixel 110 and the second sub-pixel 120 to output the same image signal. The light from the first sub-pixel 110 and the second sub-pixel 120 can pass through the conversion component 200 and reach the viewer's eye, so that the viewer can see an image signal output from the front. In the second state, the magnetic particles of the conversion component 200 change their arrangement, becoming opaque and tilted to a specified angle, making the conversion component 200 reflective. The driving circuit controls the first sub-pixel 110 and the second sub-pixel 120 to output different image signals. For example, the driving circuit controls the first sub-pixel 110 to output a first image signal, and the driving circuit controls the second sub-pixel 120 to output a second sub-pixel image. The first sub-pixel 110 is lit in the first frame, and the second sub-pixel 120 is not lit in the first frame; the first sub-pixel 110 is not lit in the second frame, and the second sub-pixel 120 is lit in the second frame. Alternatively, two sets of pixel circuits can be used to achieve separate display of the first sub-pixel 110 and the second sub-pixel without interference, satisfying the dual-view requirement. In the second state, the conversion component 200 can reflect the light output by the first sub-pixel 110 to a first designated area, allowing a person in the first designated area to observe the first image displayed by the first pixel. Similarly, the conversion component 200 can reflect the light output by the second sub-pixel 120 to a second designated area, allowing a person in the second designated area to see the second image output by the second sub-pixel 120.

[0126] For example, when the vehicle is in motion, the passenger can enjoy entertainment through the first image output by the first sub-pixel 110 displayed on the central control screen. For driving safety, the driver needs to switch to navigation reminders that are conducive to driving safety. That is, the driver can view the navigation image displayed by the second sub-pixel 120 on the central control screen, thus enabling safe driving.

[0127] The display device of this embodiment can truly achieve a dual-view effect. It can achieve both normal display and dual-view functionality using a single display device.

[0128] In this embodiment, the display device includes a pixel display area 100 and a conversion component 200 disposed on the pixel display area 100. The pixel display area 100 has a plurality of first sub-pixels 110 and a plurality of second sub-pixels 120 arranged in a plurality of configurations, with the first sub-pixels 110 and second sub-pixels 120 arranged adjacent to each other. The first sub-pixels 110 and second sub-pixels 120 can output the same image signal or output different image signals. The conversion component 200 has a first state and a second state. When the conversion component 200 is in the first state, it is transparent, i.e., it has high light transmittance. By controlling the first sub-pixels 110 and second sub-pixels 120 to output the same image signal, only one display image is displayed on the display device, facilitating multiple people to watch and discuss the same video together. When the conversion component 200 is in its second state, it is opaque and set at a specified angle, meaning its light transmittance is reduced and its reflectivity is enhanced. The first sub-pixel 110 and the second sub-pixel 120 output different image signals. The light output by the first sub-pixel 110 is reflected by the conversion component 200 to the first corresponding area, allowing the viewer in that area to see the first image output by the first sub-pixel 110. Similarly, the light output by the second sub-pixel 120 is reflected by the conversion component 200 to the second corresponding area, allowing the viewer in that area to see the second image output by the second sub-pixel 120. This allows a single display device to output two different images to viewers in corresponding areas, providing a better viewing experience. Viewers can freely adjust the image to their liking, enabling the display device to truly achieve dual-view and normal display without interference between them, resulting in a superior display effect.

[0129] In one embodiment, the conversion component 200 includes:

[0130] Multiple first conversion elements 210 are arranged on the pixel display area 100;

[0131] Multiple second conversion elements 220 are arranged on the side of the first conversion element 210 away from the pixel display area 100;

[0132] The first converter 210 and the second converter 220 both have a first state and a second state. When each of the first converters 210 and each of the second converters 220 is in the second state, the first converter 210 is at a first specified angle and the second converter 220 is at a second specified angle. The first specified angle and the second specified angle are different angles.

[0133] In this embodiment, there are multiple first conversion elements 210 and second conversion elements 220. The first conversion element 210 can be configured corresponding to the first sub-pixel 110, and the second conversion element 220 can be configured corresponding to the second sub-pixel 120. In the first state, the driving circuit controls the first sub-pixel 110 and the second sub-pixel 120 to output the same image signal. Light from the first sub-pixel 110 and the second sub-pixel 120 can pass through the transparent first conversion elements 210 and 220 and reach the viewer's eye, allowing the viewer to see an image signal output from the front. In the second state, the magnetic particles of the first conversion elements 210 and 220 change their arrangement, becoming opaque and tilted to a specified angle. The first conversion element 210 is at a first specified angle, and the second conversion element 220 is at a second specified angle; the first and second specified angles are different angles. The first conversion element 210 and the second conversion element 220 can reflect corresponding light into corresponding areas based on different specified angles. At this time, the driving circuit controls the first sub-pixel 110 and the second sub-pixel 120 to output different image signals. For example, the driving circuit controls the first sub-pixel 110 to output a first image signal, and the driving circuit controls the second sub-pixel 120 to output a second sub-pixel 120 image. The first sub-pixel 110 is lit in the first frame, and the second sub-pixel 120 is not lit in the first frame; the first sub-pixel 110 is not lit in the second frame, and the second sub-pixel 120 is lit in the second frame. Alternatively, two sets of pixel circuits can be used to achieve separate display of the first sub-pixel 110 and the second sub-pixel 120 without interference, thus meeting the dual-view requirement. In the second state, the first conversion element 210, set at a first angle, can reflect the light output by the first sub-pixel 110 to a first designated area, allowing a person in the first designated area to observe the first image displayed by the first pixel. In the second state, the second conversion element 220, set at a second designated angle, can reflect the light output by the second sub-pixel 120 to a second designated area, allowing a person in the second designated area to see the second image output by the second sub-pixel 120.

[0134] In this embodiment, the first conversion element 210 can correspond to a portion of the first sub-pixel 110, and the second conversion element 220 can correspond to a portion of the second sub-pixel 120. Similarly, the first conversion element 210 can correspond to a portion of the second sub-pixel 120, and the second conversion element 220 can correspond to a portion of the first sub-pixel 110. Both the first conversion element 210 and the second conversion element 220 are composed of magnetic particles, such as magnetic nanoparticles. These magnetic particles are nanoparticle materials, such as nano-iron-cobalt alloy dispersed in an aluminum fluoride medium. This structure can simultaneously utilize the strong magnetism of the iron-cobalt alloy and the light transmittance of aluminum fluoride. In normal display mode, in a non-magnetic field state, the nanoparticles are transparent, thus achieving the first state of the first conversion element 210 and the second conversion element 220. In dual-view display mode, in a magnetic field state, the nanoparticles are opaque. Because they contain metal particles, they have a certain degree of reflectivity, thus achieving the second state of the first conversion element 210 and the second conversion element 220.

[0135] In this embodiment, since the first conversion element 210 and the second conversion element 220 are considered to have the same specified angle in the second state, the first conversion element 210 and the second conversion element 220 cannot be placed on the same layer. The first conversion element 210 and the second conversion element 220 can have the same shape or different shapes. The second conversion element 220 is arranged on the side of the first conversion element 210 away from the pixel display area 100, so that the first conversion element 210 and the second conversion element 220 are arranged in layers. Under the action of corresponding magnetic fields, the first conversion element 210 can be set at a first specified angle, and the second conversion element 220 can be set at a second specified angle. This avoids the problem of magnetic field interference between the first conversion element 210 and the second conversion element 220, thereby effectively controlling the reflection angles of the first conversion element 210 and the second conversion element 220 respectively. This ensures that the light from the first sub-pixel 110 is reflected to the first specified area through the first specified angle of the first conversion element 210, and the light from the second sub-pixel 120 is reflected to the corresponding second specified area through the second specified angle of the second conversion element 220.

[0136] In one embodiment, the display device further includes:

[0137] The first control unit 310 is disposed on either side of the first conversion member 210 and is used to generate a first magnetic field so that the first conversion member 210 is in a second state.

[0138] The second control unit 320 is disposed on either side of the second conversion member 220 and is used to generate a second magnetic field so that the second conversion member 220 is in a second state.

[0139] Both the first control unit 310 and the second control unit 320 can be coils, permanent magnets, or other devices capable of generating magnetic fields. In this embodiment, the first control unit 310 and the second control unit 320 can be coils. By controlling the magnetic field strength generated by the coils, the reflectivity and reflection angle of the first conversion element 210 and the second conversion element 220 can be controlled. The coil material can be ITO, Cu, etc. Transparent materials, represented by ITO, can be designed on the entire top of the screen. Opaque materials, represented by Cu, can be placed on the top, bottom, left, and right edges. The coils simultaneously realize NFC functionality. In normal display mode, the coils have NFC functionality. In dual-view display mode, that is, when the coils are activated and generate a magnetic field, the NFC functionality of the coils is turned off.

[0140] In this embodiment, there can be one or more first control units 310. If there is only one first control unit 310, it can be disposed on one side of the side bezel of the display device. The first control unit 310 generates a first magnetic field. Under the action of the first magnetic field, the first conversion element 210 switches from a first state to a second state. That is, the first conversion element 210 switches from a first state with transparent magnetic particles to a second state with opacity and a first specified angle under the action of the magnetic field. There can also be multiple first control units 310, arranged above or below the first conversion element 210. Each first control unit 310 can correspond one-to-one with the first conversion element 210, or one first control unit 310 can correspond to two first conversion elements 210, etc., so as to accurately control the emissivity and consistency of the first specified angle of the first conversion element 210 in the second state, so that each first conversion element 210 can maintain good reflectivity and the same first specified angle, thereby ensuring that the light of each first sub-pixel 110 can be reflected into the first corresponding area through the corresponding first conversion element 210, so that people in the area can clearly see the video image.

[0141] In this embodiment, there may be one or more second control units 320. If there is only one second control unit 320, it can be disposed on the other side of the side bezel of the display device. In order to avoid conflict between the first magnetic field generated by the first control unit 310 and the second magnetic field generated by the second control unit 320, the first control unit 310 and the second control unit 320 can be disposed separately, that is, disposed on the left and right sides of the bezel respectively, thereby effectively reducing the mutual interference between the first magnetic field and the second magnetic field.

[0142] A second magnetic field is generated by the second control unit 320. Under the action of the second magnetic field, the first conversion element 210 switches from a first state to a second state. That is, the first conversion element 210 switches from a first state with transparent magnetic particle arrangement to a second state with opacity and a first specified angle under the action of the magnetic field. There can also be multiple second control units 320, arranged above or below the second conversion element 220. Each second control unit 320 can correspond one-to-one with the second conversion element 220, or one second control unit 320 can correspond to two second conversion elements 220, etc., so as to accurately control the emissivity and consistency of the second specified angle of the second conversion element 220 in the second state. This ensures that each second conversion element 220 can maintain good reflectivity and the same second specified angle, thereby ensuring that the light of each second sub-pixel 120 can be reflected by the corresponding second conversion element 220 into the second corresponding area, so that people in that area can clearly see the video image.

[0143] In one embodiment, the display device further includes:

[0144] A dielectric shielding layer 250 is disposed between the first conversion element 210 and the second conversion element 220 to isolate the first magnetic field and the second magnetic field.

[0145] The dielectric shielding layer 250 is disposed between the first converter 210 and the second converter 220. The dielectric shielding layer 250 isolates the magnetic fields acting on the first converter 210 and the second converter 220, so that the first magnetic field only affects the first converter 210 and the second magnetic field only affects the second converter 220. This avoids the first magnetic field affecting the second converter 220 and causing the second specified angle of the second converter 220 to be not configured properly. Similarly, it avoids the second magnetic field affecting the first converter 210 and causing the first specified angle of the first converter 210 to be not configured properly.

[0146] In one implementation,

[0147] Multiple first control units 310 are arranged between the first conversion element 210 and the medium isolation layer;

[0148] Multiple second control units 320 are arranged between the second conversion element 220 and the medium isolation layer.

[0149] In this embodiment, there are multiple first control units 310 and second control units 320. Each first control unit 310 can correspond one-to-one with a first conversion element 210, or one first control unit 310 can correspond to two first conversion elements 210, etc. Similarly, each second control unit 320 can correspond one-to-one with a second conversion element 220, or one second control unit 320 can correspond to two second conversion elements 220, etc. Both the first control unit 310 and the second control unit 320 can be coils, permanent magnets, or other devices capable of generating magnetic fields. In this embodiment, both the first control unit 310 and the second control unit 320 can be coils. Since both the first control unit 310 and the second control unit 320 are located above the pixel display area 100, the display of both the first control unit 310 and the second control unit 320 can be made of transparent materials, such as transparent coils, which can be made of ITO material.

[0150] The first control unit 310 can be housed within a corresponding carrier, which can be made of transparent materials such as PET or PI, without affecting the light transmission of the first sub-pixel 110 and the second sub-pixel 120. By placing the first control unit 310 between the first converter 210 and the dielectric isolation layer, more precise control of the first converter 210 can be achieved. The first magnetic field generated by the first control unit 310 corresponds one-to-one with the magnetic particles of the first converter 210, ensuring that the magnetic particles of each first converter 210 are of the same size. This ensures that the light from each first sub-pixel 110 can be reflected through the corresponding first converter 210 into the first corresponding area, allowing people in that area to clearly view the video image.

[0151] The second control unit 320 can be housed within a corresponding carrier, which can be made of transparent materials such as PET or PI, without affecting the light transmission of the first sub-pixel 110 and the second sub-pixel 120. By placing the second control unit 320 between the second conversion element 220 and the dielectric isolation layer, more precise control of the second conversion element 220 can be achieved. The second magnetic field generated by the second control unit 320 corresponds one-to-one with the magnetic particles of the second conversion element 220, ensuring that the magnetic particles of each second conversion element 220 are of the same size. This ensures that the light from each second sub-pixel 120 can be reflected through the corresponding second conversion element 220 into the corresponding area, allowing people in that area to clearly view the video image.

[0152] In this embodiment, a first conversion element 210, a first control unit 310, a dielectric shielding layer 250, a second conversion element 220, and a second control unit 320 are sequentially externally attached to the prepared pixel display area 100. Specifically, the external attachment process can be achieved by nano-transfer printing.

[0153] In one embodiment, the display device further includes:

[0154] The first border area 130 is located on one side of the pixel display area 100, the first conversion element 210, and the second conversion element 220, and the first control unit 310 is disposed on the first border area 130.

[0155] The second border area 140 is located on the side of the pixel display area 100, the first conversion element 210 and the second conversion element 220 away from the first border area 130, and the second control unit 320 is disposed on the second border area 140.

[0156] In addition to the pixel display area 100, the display device also has bezel areas on the left and right sides of the pixel display area 100. For example, the left side of the pixel display area 100 is the first bezel area 130, and the right side is the second bezel area 140. By placing the first control unit 310 on the first bezel area 130 and the second control unit 320 on the second bezel area 140, the distance between the first control unit 310 and the second control unit 320 is relatively large. The first magnetic field generated by the first control unit 310 and the second magnetic field generated by the second control unit 320 are also relatively large, and the magnetic field weakens with distance. Therefore, the interference between the first magnetic field and the second magnetic field is reduced.

[0157] In some embodiments, to enable the first control unit 310 located in the first border region 130 and the second control unit 320 located in the second border region 140 to control the first conversion element 210 and the second conversion element 220, the size of the first conversion element 210 can be gradually increased in the direction gradually moving away from the first control unit 310. That is, the size of the magnetic particles is largest at the position away from the first control unit 310 and smallest at the position close to the first control unit 310. This ensures that under the action of the first control unit 310, each first conversion element 210 can undergo equal or small-error deflection under the action of the first magnetic field of the first control unit 310, thereby ensuring that the light of the first sub-pixel 110 can be reflected to the corresponding first designated area through the corresponding first conversion element 210, so that a person in the first designated area can view the corresponding first image. Similarly, the size of the second conversion element 220 can be gradually increased in the direction gradually moving away from the second control unit 320. That is, the size of the magnetic particles is largest at the position away from the second control unit 320 and smallest at the position close to the second control unit 320. This method ensures that, under the action of the second control unit 320, each second conversion element 220 undergoes the same or small-error deflection under the action of the second magnetic field of the second control unit 320, thereby ensuring that the light of the second sub-pixel 120 can be reflected to the corresponding second designated area through the corresponding second conversion element 220, so that a person in the second designated area can view the corresponding second image.

[0158] In one embodiment, the display device further includes:

[0159] The driving circuit is electrically connected to the first sub-pixel 110 and the second sub-pixel 120. The driving circuit has a switching transistor, which is used to control the first sub-pixel 110 and the second sub-pixel 120 to light up respectively.

[0160] In the embodiments of this application, under normal display conditions, the first sub-pixel 110 and the second sub-pixel 120 output the same image, and the switching transistor of the driving circuit does not need to operate. When dual-view functionality is required, the switching transistor of the driving circuit illuminates the first sub-pixel 110 and the second sub-pixel 120 separately. For example, the driving circuit controls the first sub-pixel 110 to output a first image signal, and the driving circuit controls the second sub-pixel 120 to output a second sub-pixel 120 image. The first sub-pixel 110 is illuminated in the first frame, and the second sub-pixel 120 is not illuminated in the first frame; the first sub-pixel 110 is not illuminated in the second frame, and the second sub-pixel 120 is illuminated in the second frame, etc. This allows for the control of outputting different images to the first sub-pixel 110 and the second sub-pixel 120, achieving dual-view image output. This ensures that a viewer in a first designated area can clearly see the first image output by the first sub-pixel 110, and a viewer in a second designated area can clearly see the second image output by the second sub-pixel 120.

[0161] In one embodiment, the display device further includes:

[0162] The first pixel circuit is electrically connected to the first sub-pixel 110 and is used to control the first sub-pixel 110 to output a first signal.

[0163] The second pixel circuit is electrically connected to the second sub-pixel 120 and is used to control the second sub-pixel 120 to output a second signal.

[0164] In the embodiments of this application, under normal display conditions, the first sub-pixel 110 and the second sub-pixel 120 output the same image, and the first pixel circuit and the second pixel circuit output the same image signal, so that the viewer can view the image displayed by the display device from the front.

[0165] In dual-view mode, the first pixel circuit controls the first sub-pixel 110 to output a first image signal, enabling a viewer in the first designated area to clearly see the first image output by the first sub-pixel 110. The second pixel circuit controls the second sub-pixel 120 to output a second image, enabling a viewer in the second designated area to clearly see the second image output by the second sub-pixel 120. By driving the corresponding first sub-pixel 110 and second sub-pixel 120 respectively through the first pixel circuit and the second pixel circuit, the image signals of the first sub-pixel 110 and the second sub-pixel 120 can be easily controlled, thereby ensuring that the display of the first sub-pixel 110 and the display of the second sub-pixel 120 do not interfere with each other, achieving a better dual-view effect.

[0166] In one implementation, the method further includes:

[0167] A plurality of black bodies 400 are prepared between the conversion component 200 and the pixel display area 100, wherein the black bodies 400 are respectively located above the adjacent first sub-pixel 110 and second sub-pixel 120.

[0168] In this embodiment, the blackbody 400 is made of a light-shielding black material, which can be a BM material with high light absorption or other materials with high light absorption, without limitation; the position of the blackbody 400 can be made on the package, or made on the same layer as the BM of the COE or on a different layer, or it can be made on the FMLOC touch screen, etc.

[0169] The blackbody 400 in this embodiment can absorb the light emitted by the first sub-pixel 110 and the second sub-pixel 120, thereby limiting the output viewing angle of the light from the first sub-pixel 110 and the second sub-pixel 120 and avoiding crosstalk between the first sub-pixel 110 and the second sub-pixel 120 in the case of dual view.

[0170] There are multiple black bodies 400. One or more black bodies 400 can be set at corresponding positions adjacent to each first sub-pixel 110 and second sub-pixel 120. The black bodies 400 are set between the conversion unit 200 and the pixel display area 100, so that the light output from the first sub-pixel 110 and the second sub-pixel 120 between the first sub-pixel 110 and the second sub-pixel 120 can be absorbed by the black bodies 400, thereby achieving the purpose of limiting the output viewing angle of the light from the first sub-pixel 110 and the second sub-pixel 120.

[0171] In one embodiment, the conversion component 200 further includes:

[0172] The first carrier 230 is arranged on the pixel display area 100, and each first conversion element 210 is disposed on the first carrier 230;

[0173] The second carrier 240 is arranged on the side of the first conversion element 210 away from the pixel display area 100, and each second conversion element 220 is disposed on the second carrier 240.

[0174] In this embodiment, both the first carrier 230 and the second carrier 240 can be made of PET or PI material and are transparent. The first conversion member 210 is disposed on the first carrier 230, specifically within the first carrier 230. The first carrier 230 supports and fixes the first conversion member 210, and the structure of the forming layer can be disposed on the pixel display area 100. The second conversion member 220 is disposed on the first carrier 230, specifically within the second carrier 240. The second carrier 240 supports and fixes the second conversion member 220, and the structure of the forming layer can be disposed on the pixel display area 100.

[0175] Multiple first conversion elements 210 are arranged on a first carrier 230, which is disposed on the pixel display area 100. Light emitted from each first sub-pixel 110 can pass through the first carrier 230 and illuminate the corresponding first conversion element 210. Multiple second conversion elements 220 are arranged on a second carrier 240, which is disposed on the pixel display area 100. Light emitted from each second sub-pixel 120 can pass through the second carrier 240 and illuminate the corresponding second conversion element 220.

[0176] When both the first converter 210 and the second converter 220 are in the first state, the light output from each first sub-pixel 110 and each second sub-pixel 120 can pass through the corresponding first converter 210, dielectric shielding layer 250, second carrier 240, and second converter 220 and be output to the observer's eye. Alternatively, the light output from each first sub-pixel 110 and each second sub-pixel 120 can pass through the corresponding first converter 210, first control unit 310, dielectric shielding layer 250, second carrier 240, second converter 220, and second control unit 320 and be output to the observer's eye.

[0177] When the first conversion element 210 is in the second state, the light emitted by each first sub-pixel 110 can pass through the corresponding first conversion element 210, be reflected by the first deflector 210 and emitted at a predetermined angle, and then pass through the dielectric shielding layer 250 and the second carrier 240 before being emitted into the eye of an observer in the first designated area. Alternatively, the light emitted by each first sub-pixel 110 can pass through the corresponding first conversion element 210, be reflected by the first deflector 210 and emitted at a predetermined angle, and then pass through the first control unit 310, the dielectric shielding layer 250, the second carrier 240 and the second control unit 320 before being emitted into the eye of an observer.

[0178] When the second conversion element 220 is in the second state, the light emitted by each second sub-pixel 120 passes through the first carrier 230 and the dielectric shielding layer 250 and then illuminates the corresponding second conversion element 220. Reflected by the corresponding second deflector 220, the light is emitted at a predetermined angle and delivered to the observer's eye in the first designated area. Alternatively, the light emitted by each second sub-pixel 120 passes through the first carrier 230, the first control unit 210, and the dielectric shielding layer 250 and then illuminates the corresponding second conversion element 220. Reflected by the second deflector 220, the light is emitted at a predetermined angle and delivered to the observer's eye via the second control unit 320.
