[0077] As Figure 1 shown, an embodiment of the present disclosure provides a display device, including a display panel and a light splitting component 13 disposed on the light emitting side of the display panel.

[0078] The display panel includes an angle customization structure 12 and a plurality of pixel islands arranged in an array in the row direction and the column direction.

[0079] In a specific implementation, the display panel may be one of a liquid crystal display panel (LCD), an organic light emitting diode (OLED) display panel, a quantum dot light emitting diode (QLED), a micro inorganic light emitting diode (micro LED) display panel, and a mini light emitting diode (mini LED) display panel.

[0080] As Figure 3A , Figure 3B , Figure 3C , Figure 3D shown, each pixel island includes a plurality of sub-pixel units 11. Among them, the sub-pixel unit 11 may include an R sub-pixel unit, a G sub-pixel unit, and a B sub-pixel unit, or may be other types of sub-pixel units, which are not limited in this embodiment.

[0081] As Figure 3A , Figure 3BAs shown in the figure, in this embodiment, each sub-pixel unit 11 includes a plurality of sub-sub-pixel units 111 arranged in at least one row along the row direction. Each sub-pixel unit 11 may include n sub-sub-pixel units, and the n sub-sub-pixel units may be arranged in m rows, where m = 1, 2, 3,.... That is, in this embodiment, the sub-sub-pixel units 111 of each sub-pixel unit 11 may be arranged in 1 row, with each row including n sub-sub-pixel units 111; or, the sub-sub-pixel units 111 of each sub-pixel unit 11 may be arranged in 2 rows, with each row including n / 2 sub-sub-pixel units 111; or, the sub-sub-pixel units 111 of each sub-pixel unit 11 may be arranged in m rows, with each row including n / m sub-sub-pixel units 111.

[0082] As Figure 3A shown, the sub-sub-pixel units 111 of each sub-pixel unit 11 are arranged in 3 rows. Among them, the 1st - 3rd rows are the sub-sub-pixel units included in the R sub-pixel unit, the 4th - 6th rows are the sub-sub-pixel units included in the G sub-pixel unit, and the 7th - 9th rows are the sub-sub-pixel units included in the B sub-pixel unit.

[0083] As Figure 3B shown, the sub-sub-pixel units 111 of each sub-pixel unit 11 are arranged in 2 rows. Among them, the 1st - 2nd rows are the sub-sub-pixel units included in the R sub-pixel unit, the 3rd - 4th rows are the sub-sub-pixel units included in the G sub-pixel unit, and the 5th - 6th rows are the sub-sub-pixel units included in the B sub-pixel unit.

[0084] Or, as Figure 3C 、 Figure 3D shown, in this embodiment, each sub-pixel unit 11 includes a plurality of sub-sub-pixel units 111 arranged in at least one column along the column direction. In this embodiment, each sub-pixel unit 11 may include n sub-sub-pixel units, and the n sub-sub-pixel units may be arranged in m columns, where m = 1, 2, 3,.... That is, in this embodiment, the sub-sub-pixel units 111 of each sub-pixel unit 11 may be arranged in 1 column, with each column including n sub-sub-pixel units 111; or, the sub-sub-pixel units 111 of each sub-pixel unit 11 may be arranged in 2 columns, with each column including n / 2 sub-sub-pixel units 111; or, the sub-sub-pixel units 111 of each sub-pixel unit 11 may be arranged in m columns, with each column including n / m sub-sub-pixel units 111.

[0085] As Figure 3C shown, the sub-sub-pixel units 111 of each sub-pixel unit 11 are arranged in 3 columns. Among them, the 1st - 3rd columns are the sub-sub-pixel units included in the R sub-pixel unit, the 4th - 6th columns are the sub-sub-pixel units included in the G sub-pixel unit, and the 7th - 9th columns are the sub-sub-pixel units included in the B sub-pixel unit.

[0086] As Figure 3D shown, the sub - sub - pixel units 111 of each sub - pixel unit 11 are arranged in 2 columns. Among them, the 1st - 2nd columns are the sub - sub - pixel units included in the R sub - pixel unit, the 3rd - 4th columns are the sub - sub - pixel units included in the G sub - pixel unit, and the 5th - 6th columns are the sub - sub - pixel units included in the B sub - pixel unit.

[0087] In this embodiment, the number of rows or columns of the arrangement of the sub - sub - pixel units 111 included in the sub - pixel unit 11 can be determined based on the number of sub - sub - pixel units 111 included in the sub - pixel unit 11. When the number of sub - sub - pixel units 111 included in the sub - pixel unit 11 is large, the number of rows or columns of the arrangement of the sub - sub - pixel units 111 is also large.

[0088] In some embodiments, the maximum number of sub - sub - pixel units per row or per column can be set. When the number of sub - sub - pixel units included in the sub - pixel unit exceeds the maximum number of sub - sub - pixel units, the sub - sub - pixel units are arranged in multiple rows or multiple columns.

[0089] As Figure 2 shown, the angle customization structure 11 includes angle customization units 121 corresponding to each of the sub - sub - pixel units 111; the angle customization structure 11 is used to converge the outgoing light of the multiple sub - sub - pixel units 111 included in the same sub - pixel unit 11 to the central area of the beam splitting component 13 through the angle customization units 111.

[0090] In this embodiment, by arranging the multiple sub - sub - pixel units included in the sub - pixel unit in at least one row or at least one column, the multiple sub - sub - pixel units included in the sub - pixel unit are gathered together, improving the light - emitting effect and the display effect; by setting the angle customization units included in the angle customization structure to correspond one - to - one with the sub - sub - pixel units, the angle customization units can direct the outgoing light of the corresponding sub - sub - pixel units to the opening center of the beam splitting component, thereby improving the brightness gain and the display effect of the display device.

[0091] In some embodiments, the multiple sub - sub - pixel units are arranged in multiple rows along the row direction, and the adjacent two rows of sub - sub - pixel units are arranged in a staggered manner in the row direction. In this embodiment, when the multiple sub - sub - pixel units included in each sub - pixel unit are arranged in multiple rows along the row direction, the adjacent two rows of sub - sub - pixel units are arranged in a staggered manner in the row direction.

[0092] As Figure 3AAs shown, the multiple sub - sub - pixel units 111 included in each sub - pixel unit 11 are arranged in 3 rows in the row direction. The first - row sub - sub - pixel units 111 and the second - row sub - sub - pixel units 111 are arranged with a dislocation in the row direction, and the second - row sub - sub - pixel units 111 and the third - row sub - sub - pixel units 111 are arranged with a dislocation in the row direction. Thus, when the emitted light passes through the light - control component and is emitted, the emitted light seen by the human eye forms a continuous light - emitting area, thereby alleviating the moiré problem.

[0093] In some embodiments, the multiple sub - sub - pixel units are arranged in multiple columns in the column direction, and adjacent two - column sub - sub - pixel units are arranged with a dislocation in the column direction. In this embodiment, when the multiple sub - sub - pixel units included in each sub - pixel unit are arranged in multiple columns in the row direction, adjacent two - column sub - sub - pixel units are arranged with a dislocation in the column direction.

[0094] As Figure 3C shown, the multiple sub - sub - pixel units 111 included in each sub - pixel unit 11 are arranged in 3 columns in the row direction. The first - column sub - sub - pixel units 111 and the second - column sub - sub - pixel units 111 are arranged with a dislocation in the column direction, and the second - column sub - sub - pixel units 111 and the third - column sub - sub - pixel units 111 are arranged with a dislocation in the column direction. Thus, when the emitted light passes through the light - splitting component and is emitted, the emitted light seen by the human eye forms a continuous light - emitting area, thereby alleviating the moiré problem.

[0095] In some embodiments, each sub - pixel unit includes m rows of sub - sub - pixel units, and the dislocation distance between adjacent two rows of sub - sub - pixel units is P pixel1 / m, where P pixel1 represents the pixel pitch of the sub - sub - pixel units.

[0096] As Figure 3A shown, in some embodiments, the sub - sub - pixel units 111 of each sub - pixel unit 11 are set to 3 rows. Taking the sub - sub - pixel units included in the R sub - pixel units of the first - third rows as an example, the dislocation distance between the first - row R sub - sub - pixel units 111 and the second - row R sub - sub - pixel units 111 in the row direction is P pixel1 / 3, and the dislocation distance between the second - row R sub - sub - pixel units 111 and the third - row R sub - sub - pixel units 111 in the row direction is P pixel1 / 3. The dislocation distance between the G sub - sub - pixel units included in the fourth - row G sub - pixel unit and the third - row R sub - sub - pixel units 111 in the row direction is P pixel1 / 3, and the G sub - sub - pixel units included in the fourth - row G sub - pixel unit are aligned with the first - row R sub - sub - pixel units 111 in the row direction.

[0097] Or, in some other embodiments, as Figure 3BAs shown, each sub-pixel unit 11's sub-divided sub-pixel units 111 are set to two rows, and the misalignment distance between adjacent two rows of sub-divided sub-pixel units is P pixel1 / 3, P pixel1 represents the pixel pitch of the sub-divided sub-pixel units. Taking the sub-divided sub-pixel units included in the R sub-pixel units in the 1st - 2nd rows as an example, the misalignment distance between the 1st row R sub-divided sub-pixel units 111 and the 2nd row R sub-divided sub-pixel units 111 in the row direction is P pixel1 / 3, the 2nd row R sub-divided sub-pixel units 111 are aligned with the G sub-divided sub-pixel units included in the 3rd row G sub-pixel units in the row direction, the misalignment distance between the 3rd row G sub-divided sub-pixel units and the 4th row G sub-divided sub-pixel units in the row direction is P pixel1 / 3, the B sub-divided sub-pixel units included in the 5th row B sub-pixel units are aligned with the 1st row R sub-divided sub-pixel units 111 in the row direction.

[0098] Alternatively, each sub-pixel unit includes m columns of sub-divided sub-pixel units, and the misalignment distance between adjacent two columns of sub-divided sub-pixel units is P pixel1 / m, P pixel1 represents the pixel pitch of the sub-divided sub-pixel units, so that when the emitted light passes through the light splitting component and is emitted, the emitted light seen by the human eye forms a continuous light emitting area, thereby alleviating the moiré problem.

[0099] In this embodiment, to achieve large-size multi-person naked-eye 3D light field display, the number of sub-divided sub-pixel units included in each sub-pixel unit is relatively large. For example, it can include 300 sub-divided sub-pixel units. If the sub-divided sub-pixel units are arranged in a single row, the length of a single sub-pixel unit is too long, resulting in poor display effect. By setting the sub-divided sub-pixel units into multiple rows or columns, the sub-divided sub-pixel units included in the sub-pixel unit are gathered together, with better light emitting effect and better display effect.

[0100] In some embodiments, the display information of the multiple sub-divided sub-pixel units included in each sub-pixel unit can be independently controlled, and the sub-divided sub-pixel units can emit light continuously, as Figure 4A shown; or, the sub-divided sub-pixel units can also emit light discontinuously, as Figure 4B shown.

[0101] In some embodiments, the angle customization unit corresponding to one row or one column of sub-divided sub-pixel units gradually shrinks from both ends to the center, so that the principal ray of each pixel island points to the center of the opening of the light splitting component 13. As Figure 1 shown, its shrinking relationship satisfies Among them, the starting position of the angle customization unit located at the center of the angle customization structure in the first row or column satisfies The offset value Δx between adjacent two rows or two columns of angle customization units satisfies Among them, P pixel represents the pixel pitch, D pixel represents the pixel opening width, T represents the set height of the light splitting component 13 (including the arch height main surface), t represents the placement height of the angle customization structure 12, and h represents the arch height of the angle customization structure 12.

[0102] In some embodiments, as Figure 5 shown, the angle customization structure can be directly fabricated on the display panel or separately fabricated on the glass substrate.

[0109] As shown in Figure c, for a liquid crystal display panel, a glass substrate, i.e., the second glass 105, can be attached to the color filter glass of the display panel, and then an angle customization unit 121 is formed by surface etching on the second glass 105, thereby forming an angle customization structure 12. Among them, the convex structure of the angle customization unit 121 faces the array substrate 101.

[0119] In some embodiments, the angle customization structure includes: a liquid crystal lens disposed on a side of the encapsulation layer of the display panel away from the pixel island.

[0120] In some embodiments, the angle customization structure includes: a light valve disposed on a side of the encapsulation layer of the display panel away from the pixel island.

[0121] As shown in FIG. h, for an organic light-emitting diode display panel, a liquid crystal lens or a light valve can be fabricated as the angle customization structure 12, and then the liquid crystal lens or the light valve is attached to the thin film encapsulation (TFE) layer 202 of the organic light-emitting diode display panel.

[0122] In some embodiments, as Figure 6A shown, the light splitting component 13 includes a plurality of first lens units 131, each of the first lens units 131 is correspondingly disposed with an opening area of a pixel island, and multi-person naked-eye light field display is realized through the respective first lens units 131 of the light splitting component 13. At the same time, as Figure 1 shown, the angle customization structure 12 is used to converge the emitted light of a plurality of the sub-pixel units 111 included in the same sub-pixel unit 11 to the central area of the first lens unit 131 corresponding to the sub-pixel unit 11, so as to improve the brightness gain and make the light emission of the display panel meet the usage requirements.

[0123] As Figure 7A shown, when the light splitting component 13 only includes the first lens units 131 correspondingly disposed with the opening areas of the pixel islands, the multi-person naked-eye viewing requirements can be met within the optimal viewing area. At the same time, by setting dummy pixels in the display panel to compensate for the alignment deviation, the thick black stripes formed by viewing away from the optimal area can be improved.

[0124] In some embodiments, as Figure 6BAs shown, the beam splitting component 13 further includes a plurality of second lens units, and each second lens unit is correspondingly arranged with a non-opening area of a pixel island. The angle customization structure is used to converge the outgoing light of a plurality of the sub-pixel units included in the same sub-pixel unit to the central area of the first lens unit or the second lens unit corresponding to the sub-pixel unit. That is, in this embodiment, the beam splitting component 13 includes a first lens unit 131 correspondingly arranged with the opening area of the pixel island and a second lens unit 132 correspondingly arranged with the non-opening area of the pixel island, so as to realize multi-person naked-eye light field display through the first lens unit 131 and the second lens unit 132.

[0125] As Figure 7B shown, when the beam splitting component 13 is provided with both the first lens unit 131 and the second lens unit 132 at the same time, the multi-person naked-eye viewing requirements can be met whether in the optimal viewing area or far from the optimal viewing area, and there will be no black thick lines. Therefore, there is no need to set dummy pixels, and there is no need to set alignment deviation in the horizontal direction.

[0126] In some embodiments, as Figure 8A shown, the beam splitting component 13 can be a single lens; or, as Figure 8B shown, the beam splitting component 13 can be a lens group, for example, it can be a positive and negative lens group. Among them, compared with a single lens, the positive and negative lens group has smaller aberration and stronger light control ability, and can greatly improve the crosstalk phenomenon as the angle increases in the large main lobe scenario.

[0127] In some embodiments, the angle of the beam splitting component is the same as the angle of the sub-pixel unit. In this embodiment, when the beam splitting component includes the first lens unit 131, the angle of the first lens unit 131 is the same as the angle of the sub-pixel unit; when the beam splitting component includes the first lens unit 131 and the second lens unit 132, the angles of both the first lens unit 131 and the second lens unit 132 are the same as the angle of the sub-pixel unit, so as to minimize the crosstalk of the light field display view of the display device.

[0128] As Figure 6A 、 Figure 6B shown, when the direction of the sub-pixel unit is arranged along the row direction, the first lens units are also arranged along the row direction, so as to minimize the crosstalk between the light field display views of the display device.

[0129] When the direction of the sub-pixel unit is arranged along the column direction, the first lens units are also arranged along the column direction, so as to minimize the crosstalk between the light field display views of the display device.

[0130] As Figure 6CAs shown, when the sub - pixel unit is obliquely arranged, the first lens unit is also obliquely arranged.

[0131] In some embodiments, the long - side direction of the sub - pixel unit has a preset angle with the normal direction of the long - side of the pixel island.

[0132] As Figure 9 shown, the effective viewing area of the human eye is within 30°. Within this effective viewing area, one can view naturally without shaking the head and can effectively process the viewed picture information. However, to satisfy a person's sense of presence and surrounding feeling, a viewing range of 100° is required. Currently, the largest naked - eye 3D display on the market is 110 inches (length 243.53 cm, width 136.98 cm). When viewed at a normal viewing distance of 3 meters, the viewing angle is less than 50°, far less than the 100° sense of presence required for the human eye to view information. In addition, it cannot meet the resolution requirements of a 3D Retina screen.

[0133] In this embodiment, by setting the long - side direction of the sub - pixel unit to have a preset angle with the normal direction of the long - side of the pixel island, and this angle is less than ±90° with respect to the vertical direction. That is, the sub - pixel units are arranged obliquely, thereby improving the viewing angle of 3D display.

[0134] In some embodiments, this angle can be 60°.

[0135] In this embodiment, taking this angle as 60° as an example, the principle of the present disclosure for obliquely arranging sub - pixel units to improve the viewing angle of 3D display is described in detail.

[0136] As Figure 10 shown, the included angle between the sub - pixel unit 111 and the vertical direction is 60°, and the tilt angle of the light - splitting component 13 is the same as that of the sub - pixel unit 111, which is also 60°. Among them, the main lobe angle of the sub - pixel unit 111 along the vertical direction of the light - splitting component 13 is 30°. According to trigonometric functions, the horizontal angle = the main lobe angle of the light - splitting component 13 in the vertical direction / sin30° = 60°. That is, the main lobe angle of 3D display can reach 60°, compared with the existing main lobe angle of 30°, the viewing angle of 3D display is improved. In some embodiments, the bonding of the dimming component and the display panel can adopt surface - bonding and frame - bonding processes. In the frame - bonding process, a sealant 14 can be made at the spacing between the sub - pixel units of the display panel, and silicon balls are incorporated into the sealant for support. In addition, during the manufacturing process of the dimming component, pillars can also be made between the second lens units for support, as Figure 11 shown.

[0137] In some embodiments, the display device further includes a first barrier rib. The first barrier rib is disposed between two adjacent sub-pixel units, and the height of the first barrier rib is determined based on the pitch between the sub-pixel units and a first distance between the pixel unit and the light-dimming component.

[0138] As Figure 12A shown, the first barrier rib is disposed between two adjacent sub-pixel units, that is, between pixel islands, serving as an inter-island barrier rib. By providing the first barrier rib, it is ensured that light only exits within the main lobe angle and does not exit outside the main lobe angle, thereby improving the moiré phenomenon and enhancing the display effect.

[0139] As Figure 12A shown, the height of the first barrier rib can be P AA × tanθ, where P AA is the pitch between the sub-pixel units, and tanθ can be determined based on the first distance between the pixel unit and the light-splitting component.

[0140] In some embodiments, the display device further includes a second barrier rib. The second barrier rib is disposed between two adjacent sub-sub-pixel units, and the height of the second barrier rib is determined based on the pitch between the sub-sub-pixel units and a second distance between the sub-sub-pixel unit and the light-splitting component.

[0141] As Figure 12B shown, the second barrier rib is disposed between two adjacent sub-sub-pixel units, serving as an intra-island barrier rib. By providing the second barrier rib, it is ensured that light only exits within the main lobe angle and does not exit outside the main lobe angle, thereby improving the moiré phenomenon and enhancing the display effect.

[0142] As Figure 12B shown, the height of the intra-island barrier rib is P pixel × tanθ, where P pixel is the pitch between the pixel units, and tanθ can be determined based on the second distance between the sub-sub-pixel unit and the light-control component. By providing the second barrier rib, it is ensured that light only exits within the main lobe angle and does not exit outside the main lobe angle, thereby improving the moiré phenomenon and enhancing the display effect.

[0143] Based on the same inventive concept, corresponding to the display device described in any of the above embodiments, the present disclosure further provides a tiled display device, which includes a plurality of display devices, and the plurality of display devices are tiled and displayed in a preset arrangement order. Among them, the display device is used to achieve autostereoscopic 3D display.

[0144] In the related art, a common autostereoscopic 3D display device is a single screen, which can support a maximum of 110 inches (243.53 cm in length and 136.98 cm in width), and cannot meet the viewing field range of multiple people.

[0145] In this embodiment, by splicing and displaying multiple display devices capable of realizing naked-eye 3D display in a preset arrangement order, large-size naked-eye 3D display is achieved, which can meet the viewing field ranges of multiple people.

[0146] In some embodiments, as Figure 13A shown, multiple display devices can be spliced to realize a naked-eye light field display device with an ultra-large size and an ultra-wide viewing field.

[0147] In some embodiments, multiple said display devices are spliced in an arc. Among them, by rotating the display device by a preset angle in the horizontal direction, the arc splicing of multiple display devices is realized.

[0148] As Figure 13B shown, in this embodiment, multiple display devices adopt an arc splicing method to reduce edge crosstalk, limit the maximum crosstalk angle within the main lobe angle, and improve the viewing experience of viewers.

[0149] Among them, the designed viewing distance is the center of the circle. If the number of spliced display devices is odd, the central display device needs not to rotate, the edge display devices rotate by an angle θ, and the other display devices rotate according to the rotation angle of: N is the number of display devices, a positive integer. If the number of spliced display devices is even, the edge display devices need to rotate by an angle θ, and the other display devices rotate according to the rotation angle of: N is the number of display devices, a positive integer.

[0150] As Figure 13C shown, by splicing the display device rows, an ultra-large-size and ultra-wide-viewing-field naked-eye light field display is realized.

[0151] In some embodiments, the binding wiring of the display device adopts a glass side wiring technology, and the binding is carried out behind the glass, so as to achieve a seamless splicing effect of the spliced display device.

[0152] In some embodiments, the spliced display device includes the display device described in any one of the above embodiments, so that while realizing an ultra-large-size and ultra-wide-viewing-field naked-eye light field display, the brightness gain can be improved and the display effect of the display device can be enhanced.

[0153] In some embodiments, as Figure 14A 、 Figure 14B shown, the effective light-emitting area of the display device can be set to one-fourth of the size of the entire display device. After splicing, the light-emitting area accounts for one-half in both the horizontal and vertical directions, and the splicing seam also accounts for one-half in both the horizontal and vertical directions, which can meet the seamless splicing effect.

[0154] Based on the same inventive concept, corresponding to the splicing display device described in any of the above embodiments, the present disclosure further provides a display system, including a plurality of splicing display devices as described in the above embodiments, a human eye tracking module, a content generation module, and a driving module, as Figure 15A shown.

[0155] The human eye tracking module is used to obtain the fixation point position of the human eye on the splicing display device. Among them, the human eye tracking module may include a camera group and a CPU processing unit. The camera group is used to provide the position of the human eye in space relative to the splicing display device and the fixation point position of the human eye on the splicing display device. The CPU processing unit is used to process relevant information. The camera can use a binocular camera or a TOF (Time of flight) camera for tracking, and can use a combination of multiple TOF cameras, or a combination of a TOF camera and an RGB camera or a grayscale camera.

[0156] The content generation module is used to generate first multi-viewpoint image data according to the fixation point position, and segment the first multi-viewpoint image data based on the splicing manner of the display devices in the splicing display device to obtain second multi-viewpoint image data, as Figure 15C shown.

[0157] The driving module is used to arrange the second multi-viewpoint image data according to the splicing manner of the display device, and transmit the data after arrangement to the splicing display device to perform image display on the splicing display device based on the fixation point position.

[0158] Among them, as Figure 15B shown, the driving module includes a PC (high-speed hard disk, high-speed DDR, and processor), a sending card, and a receiving card (Tcon, etc.). Among them, data is transmitted between the sending card and the receiving card using Ethernet or optical fiber. Among them, the data can use a compression algorithm to reduce the data volume. As Figure 15D shown, all multi-viewpoint video sources are stored on the hard disk. The processor program will make a judgment and decision for each frame according to the front-end human eye tracking coordinates, and directly select the required viewpoint video sources from the hard disk for transmission. Fast reading speed is achieved through a high-speed hard disk and high-speed DDR. In addition, if it is an image video source or a short-duration video source, all multi-viewpoint video sources can be pre-loaded into the memory in advance, and no front-end resources are required.

[0159] In some embodiments, after generating the second multi-viewpoint image data, the content generation module compresses the second multi-viewpoint image data, and then transmits the compressed data to the driving module. The driving module decompresses the data and then performs data compensation, and then performs data arrangement.
