The line connecting the middle line of each sub-pixel unit 101211 extending along the first direction F1 and the middle line of the corresponding angle customization lens 103 extending along the first direction F1 away from the side of the substrate substrate 1011 points to the first middle axis u of the first lens close to the side of the substrate substrate 1011 along the first direction F1. Or it can be understood that the corresponding arrangement means that the light emitted by the sub-pixel unit 101211 can be irradiated to the first middle axis u of the first lens 10211 close to the side of the substrate substrate 1011 along the first direction F1 after passing through the corresponding angle customization lens 103. Of course, the corresponding arrangement does not mean that the middle line of the normal projection of the angle customization lens 103 on the substrate substrate 1011 overlaps the middle line of the normal projection of the corresponding sub-pixel unit 101211 on the substrate substrate 1011, but needs to meet a certain size relationship.

[0131] Optionally, in order to ensure the continuity of the display picture in the second direction F2, the width of each sub-pixel unit 101211 in the sub-pixel group 10121z in the second direction F2 can be greater than or equal to 1 / n of the period size of the plurality of sub-pixel units 101211 in the sub-pixel group 10121z. N can be used to represent the number of sub-pixel groups 10121z included in the pixel unit 10121. For example, the pixel unit 10121 includes two sub-pixel groups 10121z, and the width of the sub-pixel unit 101211 in the second direction F2 can be greater than or equal to 1 / 2 of the period size of the plurality of sub-pixel units 101211 in the sub-pixel group 10121z. Of course, the pixel unit 10121 can include a larger number of sub-pixel groups 10121z, and the number of sub-pixel groups 10121z included in the pixel unit 10121 is not limited in the present application.

[0132] Optionally, in the case where the width of the sub-pixel unit 101211 in the second direction F2 in the sub-pixel group 10121z is equal to 1 / n of the period size of the plurality of sub-pixel units 101211 in the sub-pixel group 10121z, the boundaries of the sub-pixel units 101211 in the first direction F1 in the plurality of sub-pixel groups 10121z can be sequentially abutted in the second direction F2. In this way, the display screen can be continuous in the second direction F2. Of course, the width of the sub-pixel unit 101211 in the second direction F2 in the sub-pixel group 10121z can also be greater than 1 / n of the period size of the plurality of sub-pixel units 101211 in the sub-pixel group 10121z, that is, the distance between the boundary of one sub-pixel unit 101211 in the first direction F1 in any one of the plurality of sub-pixel groups 10121z and the center line of a certain sub-pixel unit 101211 in the first direction F1 in another sub-pixel group 10121z in the second direction F2 is less than the distance between the boundary of the certain sub-pixel unit 101211 in the first direction F1 and the center line in the first direction F1 in the another sub-pixel group 10121z in the second direction F2.

[0133] It should be noted that the greater the width of the sub-pixel unit 101211 in the second direction F2 in the sub-pixel group 10121z, the smaller the interval between adjacent sub-pixel units 101211 in the sub-pixel group 10121z, and the greater the difficulty of preparation. Therefore, in order to reduce the difficulty of preparation of the sub-pixel unit 101211 while ensuring the continuity of the display screen, the width of the sub-pixel unit 101211 in the second direction F2 in the sub-pixel group 10121z can be preferably equal to 1 / n of the period size of the plurality of sub-pixel units 101211 in the sub-pixel group 10121z.

[0134] Reference Figure 10 The first lens 10211 includes a first plane a1 close to the display device 101 and a first curved surface a2 away from the display device 101. The light emitted by the display device 101 can change the light emission direction (light divergence) after being incident on the first central axis u extending in the first direction F1 on the first plane a1. Among them, Figure 10 The first central axis in the above is represented by a small white dot, which represents that the first central axis u is perpendicular to the current paper surface. The first curved surface a2 of the first lens 10211 is convexly arranged away from the display device 101. The reason why the light emitted by the display device 101 changes the light emission direction when being incident on the first plane a1 is that the refractive index of the first lens 10211 is different from the refractive index of the medium close to the display device 101. In Figure 10 The scheme shown in the above can use the first lens 10211 to control the light.

[0135] Reference Figure Figure 8, Figure 9 , Figure 11 and Figure 12 The light control unit 1021 further includes a second lens 10212 located on the side of the first lens 10211 away from the display device 101. The second lens 10212 also extends along the first direction F1. The second lens 10212 includes a second curved surface a3 close to the display device 101 and a second flat surface a4 away from the display device 101. After the light emitted by the display device 101 irradiates the first central axis u of the first curved surface a2 extending along the first direction F1, the light irradiates the second curved surface a3 and the second flat surface a4 in turn, and the light direction of the light at the second curved surface a3 and the second flat surface a4 changes. Among them, the light converges at the second curved surface a3 and diverges at the second flat surface a4. That is, the light can be emitted after diverging, converging and diverging in turn.

[0136] Optionally, when the light irradiates the second curved surface a3, the light can be refracted at the second curved surface a3 because the refractive index of the second lens 10212 is different from the refractive index of the medium between the first lens 10211 and the second lens 10212. At the same time, when the light irradiates the second flat surface a4, the light can also be refracted at the second flat surface a4 because the refractive index of the second lens 10212 is different from the refractive index of the medium on the side of the second lens 10212 away from the display device 101.

[0137] Optionally, referring to Figure 8 and Figure 11 The second curved surface a3 of the second lens 10212 is concavely arranged away from the display device 101. That is, in the scheme shown in Figure 8 and Figure 11 The light control unit 1021 can be a combination structure of one concave lens (second lens) and one convex lens (first lens). The light control device 102 can be obtained by bonding a concave lens array (a plurality of concave lenses) and a convex lens array (a plurality of convex lenses).

[0138] Alternatively, referring to Figure 9 and Figure 12 The second curved surface a3 of the second lens 10212 is convexly arranged close to the display device 101. That is, in the scheme shown in Figure 9 and Figure 12 The light control unit 1021 can be a combination structure of two convex lenses. The light control device 102 can be obtained by bonding two convex lens arrays (each convex lens array includes a plurality of convex lenses) in reverse.

[0139] In the embodiments of the present application, referring to Figure 1 and Figures 7 to 12It can be seen that the display unit 100 further comprises a spacer structure 104 between the display device 101 and the light control device 102. The spacer structure 104 can have a certain thickness, the light control device 102 can be arranged at a certain position of the display surface 101a of the display device 101 to achieve the light control effect of the light control device 102, and the spacer structure 104 can support the light control device 102. Optionally, the spacer structure 104 can be a spacer glass.

[0140] Optionally, in the scheme shown, Figures 4 to 6 In the scheme shown, the first direction F1 and the third direction F3 are parallel, and the second direction F2 and the fourth direction F4 are parallel. That is, the extension direction (length direction) of the light control unit 1021 can be parallel to the arrangement direction of the sub-pixel group 10121z and the extension direction of the sub-pixel unit 101211, and the width direction of the light control unit 1021 can be parallel to the arrangement direction of the plurality of sub-pixel units 101211.

[0141] Optionally, referring to Figure 13 The shape of the orthographic projection of the pixel island 1012 on the substrate 1011 can be a rectangle. Assuming that the periodic size of the pixel island 1012 in the second direction F2 is P, the effective area size of the pixel island 1012 is P / 2, the interval size between the effective areas of the pixel islands 1012 arranged in the second direction F2 is P / 2, the extension direction (length direction) of the light control unit 1021 is parallel to the arrangement direction of the sub-pixel group 10121z and the extension direction of the sub-pixel unit 101211, and the periodic size of the light control unit 1021 in the second direction F2 can be the same as the periodic size of the pixel island 1012 in the second direction F2, that is, the same column of pixel islands 1012 arranged in the first direction F1 can correspond to the same light control unit 1021. Figure 13 The gray solid line in indicates the outline of the light control unit 1021.

[0142] Optionally, referring to Figure 14The shape of the orthographic projection of the pixel island 1012 on the substrate 1011 can be a rectangle. Assuming that the periodic size of the pixel island 1012 in the second direction F2 is P, the effective area size of the pixel island 1012 is P / 2, the interval size between the effective areas of the pixel islands 1012 arranged along the second direction F2 is P / 2, the extension direction (long side direction) of the light control unit 1021 and the arrangement direction of the sub-pixel group 10121z and the extension direction of the sub-pixel unit 101211 are parallel, and the periodic size of the light control unit 1021 in the second direction F2 can be half of the periodic size of the pixel island 1012 in the second direction F2 (i.e., the periodic size is P / 2), that is, the same column of pixel islands 1012 arranged along the first direction F1 can correspond to two light control units 1021, one of which covers the pixel island 1012 and the other of which is located between the two adjacent pixel islands 1012. Figure 14 The gray solid line in FIG. 10B represents the outline of the light control unit 1021.

[0143] In order to make the light emitted by the sub-pixel unit 101211 pass through the corresponding angle customization lens 103 and then irradiate to the first lens 10211 of the light control unit 1021 close to the first central axis u of the side of the substrate 1011, the line connecting the center line of the sub-pixel unit 101211 and the center line of the angle customization lens 103 away from the side of the substrate 1011 can be directed to the first central axis u of the side of the first lens 10211 close to the substrate 1011. Wherein, the line connecting between two lines can be a line segment perpendicular to the two lines. Referring to FIG. 10B, Figure 15 Taking the light control unit 1021 as an example, the periodic size P of the angle customization lens 103 lens The following conditions can be met:

[0144]

[0145] In the above formula (1), T is the distance between the side of the light control unit 1021 close to the substrate 1011 and the light emitting surface of the sub-pixel unit 101211 away from the substrate 1011. t is the distance between the side of the angle customization lens 103 close to the substrate 1011 and the light emitting surface of the sub-pixel unit 101211 away from the substrate 1011. h is the height of the angle customization lens 103. P pixel is the periodic size of the sub-pixel unit 101211. Optionally, the above formula (1) can be derived from the triangle similarity theorem under the condition that the line connecting the center line of the sub-pixel unit 101211 and the center line of the angle customization lens 103 away from the side of the substrate 1011 is directed to the first central axis u of the side of the first lens 10211 close to the substrate 1011.

[0146] In the embodiments of the present application, referring to Figure 5 and Figure 6 The plurality of sub-pixel units 101211 in the pixel island 1012 are long strips, and the corresponding angle customization lenses 103 are also long strips. Each angle customization lens 103 corresponds to a sub-pixel unit 101211, and realizes independent control of the sub-pixel unit 101211. Optionally, the pixel unit 10121 includes at least two sub-pixel groups 10121z arranged along the third direction F3, and the plurality of angle customization lenses 103 corresponding to the pixel unit 10121 are also at least two angle customization lens groups 103z arranged along the third direction F3. Figure 6 Two sub-pixel groups 10121z and two angle customization lens groups 103z are shown in FIG.

[0147] In Figure 6 In the case where the angle customization lens 103 is provided, in order to ensure the continuity of the display picture, the width of the angle customization lens 103 in the angle customization lens group 103z along the second direction F2 can be greater than or equal to 1 / n of the period size of the plurality of sub-pixel units 101211 in the sub-pixel group 10121z. For example, the pixel unit 10121 includes two sub-pixel groups 10121z, and the width of the angle customization lens 103 along the second direction F2 can be greater than or equal to 1 / 2 of the period size of the plurality of sub-pixel units 101211 in the sub-pixel group 10121z.

[0148] Optionally, in the case where the width of the angle customization lens 103 in the angle customization lens group 103z along the second direction F2 is equal to 1 / n of the period size of the plurality of sub-pixel units 101211 in the sub-pixel group 10121z, the boundaries of the angle customization lenses 103 in the plurality of angle customization lens groups 103z along the first direction F1 can be sequentially and tightly arranged along the second direction F2. In this way, the continuity of the display picture along the second direction F2 can be ensured. Of course, the width of the angle customization lens 103 in the angle customization lens group 103z along the second direction F2 can also be greater than 1 / n of the period size of the plurality of sub-pixel units 101211 in the sub-pixel group 10121z, that is, the distance between the boundary of the angle customization lens 103 in any angle customization lens group 103z along the first direction F1 and the center line of the angle customization lens 103 in another angle customization lens group 103z along the first direction F1 along the second direction F2 is less than the distance between the boundary of the angle customization lens 103 in the angle customization lens group 103z along the first direction F1 and the center line of the angle customization lens 103 in the angle customization lens group 103z along the first direction F1 along the second direction F2.

[0149] It should be noted that the greater the width of the angle-tailored lens 103 in the angle-tailored lens group 103z along the second direction F2, the smaller the interval between adjacent angle-tailored lenses 103 in the angle-tailored lens group 103z, and the greater the difficulty of preparation. Therefore, in order to reduce the difficulty of preparation of the angle-tailored lens 103 while ensuring the continuity of the display screen, the width of the angle-tailored lens 103 in the angle-tailored lens group 103z along the second direction F2 can be equal to 1 / n of the periodic size of the plurality of angle-tailored lenses 103 in the angle-tailored lens group 103z.

[0150] Optionally, the angle-tailored lens 103 can be formed by a heat reflow process to form a lens surface of the lens material. It should be noted that the angle-tailored lens 103 can be formed by a heat reflow process to form a lens surface of the lens material. Figure 16 The side of the angle-tailored lens 103 away from the substrate 1011 can be covered by a medium layer J. The refractive index of the angle-tailored lens 103 can be greater than the refractive index of the medium layer J. For example, the refractive index of the angle-tailored lens 103 can be in the range of 1.5 to 1.7, such as 1.6. The refractive index of the medium layer J can be in the range of 1.4 to 1.6, such as 1.5. Optionally, the material of the medium layer J can be a low-refractive material.

[0151] Of course, the side of the angle-tailored lens 103 away from the substrate 1011 can also not be covered by the medium layer J. That is, the medium on the side of the angle-tailored lens 103 away from the substrate 1011 can be air.

[0152] Optionally, referring to Figure 2 The display device can be an organic light-emitting diode (OLED) display device. Alternatively, the display device can be a liquid crystal display (LCD) display device. Alternatively, the display device can be any appropriate display device.

[0153] If the display device is an OLED display device, the display device includes a substrate, a plurality of pixel islands arranged in an array on one side of the substrate, and an encapsulation film layer on the side of the plurality of pixel islands away from the substrate. The encapsulation film layer includes at least an inorganic material, and the angle-tailored lens 103 can be located on the side of the encapsulation film layer away from the substrate. That is, the angle-tailored lens 103 can be formed on the side of the encapsulation film layer away from the substrate by a heat reflow process.

[0154] If the display device is an LCD display device, the display device includes a substrate, a plurality of pixel islands arranged in an array on one side of the substrate, and a glass cover plate on a side of the plurality of pixel islands away from the substrate. The angle-tailored lens can be on a side of the glass cover plate away from the substrate. That is, the angle-tailored lens 103 can be formed on the side of the glass cover plate away from the substrate by a hot reflow process.

[0155] In the embodiments of the present application, referring to Figure 1 and Figure 17 , the display unit further includes a connecting structure 105 and a spacer structure 104. The connecting structure 105 has a projection on the substrate 1011 that is located in the interval between the projections of the adjacent pixel islands 1012 on the substrate 1011. One side of the connecting structure 105 is connected to the display device 101, and the other side of the connecting structure 105 is connected to one side of the spacer structure 104. The other side of the spacer structure 104 is connected to the light control unit 1021.

[0156] Optionally, referring to Figure 17 , the connecting structure 105 can be a strip-shaped structure extending along the first direction F1. Of course, the connecting structure 105 can also be other shapes, such as a polygonal block structure or a circular block structure. In addition, the connecting structure 105 can be periodic or non-periodic. The embodiments of the present application do not limit this. Optionally, the connecting structure 105 can be a sealant.

[0157] Optionally, in the case where the display unit 100 includes the angle-tailored lens 103, the thickness of the connecting structure 105 in the direction perpendicular to the display surface 101a of the display device 101 can be greater than or equal to the height of the angle-tailored lens 103, so that the connecting structure 105 can support the spacer structure 104 and avoid the spacer structure 104 affecting the angle-tailored lens 103.

[0158] In the embodiments of the present application, referring to Figure 18 , the display device 101 can include a plurality of sub-display devices 101v arranged in an array in the first direction F1 and the second direction F2. The shape of the sub-display device 101 can be rectangular. The light-emitting area of the display device 101 includes oppositely arranged first and second boundaries c1 and c2, and oppositely arranged third and fourth boundaries c3 and c4. The first and second boundaries c1 and c2 of the display device 101 are parallel to the first direction F1, and the third and fourth boundaries c3 and c4 of the display device 101 are parallel to the second direction F2. That is, the display device 101 can be formed by splicing a plurality of sub-display devices 101v in the first direction F1 and the second direction F2.

[0159] Of course, the display device 101 can also not be spliced by multiple sub-display devices 101v, but be a large-size independent display device 101. Embodiments of the present application do not limit this.

[0160] In the embodiments of the present application, referring to Figure 19 , the plurality of pixel islands 1012 can include first pixel islands 1012a and second pixel islands 1012b arranged along the second direction F2 and adjacent to each other. The first pixel islands 1012a and the first light control units 1021a are correspondingly arranged, and the first light control units 1021a are used to control the light emission direction of the first pixel islands 1012a. The second pixel islands 1012b and the second light control units 1021b are correspondingly arranged, and the second light control units 1021b are used to control the light emission direction of the second pixel islands 1012b. Among them, the first pixel islands 1012a and the second pixel islands 1012b are any two pixel islands 1012 arranged along the second direction F2 and adjacent to each other in the plurality of pixel islands 1012.

[0161] In order to avoid the light of the first pixel island 1012a irradiating to the second light control unit 1021b and affecting the light control effect of the second light control unit 1021b, referring to Figure 19 , the display device 101 can also include a first barrier wall portion 106 located between the first pixel island 1012a and the second pixel island 1012b. That is, the orthographic projection of the first barrier wall portion 106 on the substrate 1011 can be located in the non-light-emitting area of the pixel island 1012, avoiding the influence of the first barrier wall portion 106 on the normal light emission of the first pixel island 1012a.

[0162] Optionally, the first barrier wall portion 106 is used to shield the light of the first pixel island 1012a irradiating to the second light control unit 1021b, and the height h1 of the first barrier wall portion 106 can satisfy:

[0163] h1≥x1*tanα1 Formula (2)

[0164] In the above formula (2), x1 is the distance between the side of the first barrier wall portion 106 away from the second pixel island 1012b and the side of the first pixel island 1012a away from the second pixel island 1012b. α1 is the included angle between the first line k1 and the display surface 101a of the display device 101, and the first line k1 is the line connecting the side of the first pixel island 1012a away from the second pixel island 1012b and the side of the second light control unit 1021b close to the first light control unit 1021a.

[0165] Similarly, in order to avoid the light of the second pixel island 1012b irradiating to the first light control unit 1021a and affecting the light control effect of the first light control unit 1021a, referring to Figure 19The display device 101 can further include a second barrier wall portion 107 between the first pixel island 1012a and the second pixel island 1012b.

[0166] Optionally, the second barrier wall portion 107 is configured to shield the light emitted by the second pixel island 1012b from the first light control unit 1021a. The height h2 of the second barrier wall portion 107 can satisfy the following formula (3):

[0167] h2≥x2*tanα2 Formula (3)

[0168] In the above formula (3), x2 represents the distance between the side of the second barrier wall portion 107 away from the first pixel island 1012a and the side of the second pixel island 1012b away from the first pixel island 1012a. α2 represents the angle between the second connecting line k2 and the display surface 101a of the display device 101. The second connecting line k2 is the connecting line between the side of the second pixel island 1012b away from the first pixel island 1012a and the side of the first light control unit 1021a close to the second light control unit 1021b.

[0169] In the above Figure 19 , the grid-shaped filled strip structure represents the pixel island 1012, the dot-shaped filling above the pixel island 1012 represents the medium (such as air) between the pixel island 1012 and the display device 101, the white-filled rectangle represents the spacer layer 103, and the arc-shaped curve above the spacer layer 103 represents the light control unit 1021. Optionally, the material of the connecting structure 105 can be a light-shielding material with adhesion. The material of the connecting structure 105 with adhesion can achieve reliable connection between the display device 101 and the spacer layer 103. Referring to Figure 20 , the material of the connecting structure 105 is a light-shielding material, which can make the connecting structure 105 multiplexed as the first barrier wall portion 106 and / or the second barrier wall portion 107, so that the connecting structure 105 can achieve the function of shielding light, i.e., the connecting structure 105 can act as a barrier wall portion between the pixel islands.

[0170] It should be noted that the first barrier wall portion 106 and the second barrier wall portion 107 between the first pixel island 1012a and the second pixel island 1012b can share a barrier wall portion, which can simultaneously shield the light emitted by the first pixel island 1012a towards the second light control unit 1021b and the light emitted by the second pixel island 1012b towards the first light control unit 1021a.

[0171] In the embodiments of the present application, in order to ensure that the light emitted by each sub-pixel unit 101211 in the pixel island 1012 can irradiate to the corresponding light control unit 1021 and will not irradiate to the light control unit 1021 corresponding to the adjacent pixel island 1012, the third barrier portion 108 can be arranged between the sub-pixel units 101211 adjacent to each other in the pixel island 1012 along the fourth direction F4.

[0172] Optionally, referring to Figure 21 , taking the fourth pixel island 1012d, the third pixel island 1012c and the fifth pixel island 1012e as any three pixel islands 1012 arranged along the second direction F2, and taking the third pixel island 1012c and the third light control unit 1021c corresponding to each other, the fourth pixel island 1012d and the fourth light control unit 1021d corresponding to each other, and the fifth pixel island 1012e and the fifth light control unit 1021e corresponding to each other as an example.

[0173] For the third pixel island 1012c, the light of the plurality of sub-pixel units 101211 on the side of the third pixel island 1012c close to the fourth pixel island 1012d (or can be referred to as the side away from the fifth pixel island 1012e) is more likely to irradiate to the fourth light control unit 1021d corresponding to the fourth pixel island 1012d than the light of the plurality of sub-pixel units 101211 on the side of the third pixel island 1012c away from the fourth pixel island 1012d (or can be referred to as the side close to the fifth pixel island 1012e). Similarly, the light of the plurality of sub-pixel units 101211 on the side of the third pixel island 1012c close to the fifth pixel island 1012e (or can be referred to as the side away from the fourth pixel island 1012d) is more likely to irradiate to the fifth light control unit 1021e corresponding to the fifth pixel island 1012e than the light of the plurality of sub-pixel units 101211 on the side of the third pixel island 1012c away from the fifth pixel island 1012e (or can be referred to as the side close to the fourth pixel island 1012d).

[0174] Therefore, as Figure 21 indicated, taking the center of the third light control unit 1021c corresponding to the third pixel island 1012c as a boundary line, the third barrier portion 108 between the adjacent sub-pixel units 101211 of the plurality of sub-pixel units 101211 on the side of the third pixel island 1012c close to the fourth pixel island 1012d and the third barrier portion 108 between the adjacent sub-pixel units 101211 of the plurality of sub-pixel units 101211 on the side of the third pixel island 1012c close to the fifth pixel island 1012e are respectively designed.

[0175] Optionally, the third barrier wall portion 108 between the plurality of sub-pixel units 101211 on the side of the third pixel island 1012c close to the fourth pixel island 1012d has a setting rule that: one of the closest sub-pixel units 101211 on the side of the third barrier wall portion 108 close to the fourth pixel island 1012d is close to the edge of the third barrier wall portion 108, and the edge of the third light control unit 1021c close to the fifth light control unit 1021e is connected (referred to as the third connecting line k3); one of the closest sub-pixel units 101211 on the side of the third barrier wall portion 108 close to the fifth pixel island 1012e is away from the edge of the third barrier wall portion 108, and the edge of the fourth light control unit 1021d close to the third light control unit 1021c is connected (referred to as the fourth connecting line k4). The cooperation relationship between the width and the height of the third barrier wall portion 108 needs to meet: the top end of the side of the third barrier wall portion 108 close to the fourth pixel island 1012d is lower than the third connecting line k3, and the top end of the side of the third barrier wall portion 108 close to the fifth pixel island 1012e is higher than the fourth connecting line k4.

[0176] In this way, for the plurality of sub-pixel units 101211 on the side of the third pixel island 1012c close to the fourth pixel island 1012d, the light emitted by the sub-pixel units 101211 can irradiate to the third light control unit 1021c, and will not irradiate to the fourth light control unit 1021d due to the shielding of the third barrier wall portion 108.

[0177] Similarly, the third barrier wall portion 108 between the plurality of sub-pixel units 101211 on the side of the third pixel island 1012c close to the fifth pixel island 1012e has a setting rule that: one of the closest sub-pixel units 101211 on the side of the third barrier wall portion 108 close to the fifth pixel island 1012e is close to the edge of the third barrier wall portion 108, and the edge of the third light control unit 1021c close to the fourth light control unit 1021d is connected (referred to as the fifth connecting line k5); one of the closest sub-pixel units 101211 on the side of the third barrier wall portion 108 close to the fourth pixel island 1012d is away from the edge of the third barrier wall portion 108, and the edge of the fifth light control unit 1021e close to the third light control unit 1021c is connected (referred to as the sixth connecting line k6). The cooperation relationship between the width and the height of the third barrier wall portion 108 needs to meet: the top end of the side of the third barrier wall portion 108 close to the fifth pixel island 1012e is lower than the fifth connecting line k5, and the top end of the side of the third barrier wall portion 108 close to the fourth pixel island 1012d is higher than the sixth connecting line k6.

[0178] In this way, for the plurality of sub-pixel units 101211 on the side of the third pixel island 1012c close to the fifth pixel island 1012e, the light emitted by the sub-pixel units 101211 can irradiate to the third light control unit 1021c, and will not irradiate to the fifth light control unit 1021e due to the shielding of the third barrier wall portion 108.

[0179] Optionally, in order to make the top end of the third barrier wall part 108 between the plurality of sub-pixel units 101211 located on the side of the third pixel island 1012c close to the fourth pixel island 1012d lower than the side of the fourth pixel island 1012d close to the third barrier wall part 108, the third barrier wall part 108 between the first sub-pixel unit y1 (referred to as the first sub-pixel unit y1) and the second sub-pixel unit y2 (referred to as the second sub-pixel unit y2) close to the fourth pixel island 1012d in the third pixel island 1012c can be designed, and the height h31 of the third barrier wall part 108 satisfies: Figure 21 and Figure 22 Optionally, in order to make the top end of the third barrier wall part 108 between the plurality of sub-pixel units 101211 located on the side of the third pixel island 1012c close to the fourth pixel island 1012d lower than the side of the fourth pixel island 1012d close to the third barrier wall part 108, the third barrier wall part 108 between the first sub-pixel unit y1 (referred to as the first sub-pixel unit y1) and the second sub-pixel unit y2 (referred to as the second sub-pixel unit y2) close to the fourth pixel island 1012d in the third pixel island 1012c can be designed, and the height h31 of the third barrier wall part 108 satisfies:

[0180] h31≤x31*tanα31 Formula (4)

[0181] Wherein, x31 is the distance between the side of the third barrier wall part 108 between the first sub-pixel unit y1 and the second sub-pixel unit y2 close to the first sub-pixel unit y1 and the side of the first sub-pixel unit y1 close to the third barrier wall part 108. The first sub-pixel unit y1 and the second sub-pixel unit y2 are the first sub-pixel unit y1 and the second sub-pixel unit y2 close to the first arrangement edge among the plurality of sub-pixel units 101211 arranged along the fourth direction F4. Optionally, the first arrangement edge is the edge of the plurality of sub-pixel units 101211 in the third pixel island 1012c close to the fourth pixel island 1012d. α31 is the included angle between the third connecting line k3 and the display surface 101a, and the third connecting line k3 is the connecting line of the edge of the first sub-pixel unit y1 close to the third barrier wall part 108 and the edge of the light control unit 1021 corresponding to the first sub-pixel unit y1 close to the side of the second sub-pixel unit y2.

[0182] In order to make the top end of the third barrier wall part 108 between the plurality of sub-pixel units 101211 located on the side of the third pixel island 1012c close to the fourth pixel island 1012d higher than the side of the fourth pixel island 1012d close to the fifth pixel island 1012e, the third barrier wall part 108 between the first sub-pixel unit y1 (referred to as the first sub-pixel unit y1) and the second sub-pixel unit y2 (referred to as the second sub-pixel unit y2) close to the fourth pixel island 1012d in the third pixel island 1012c can be designed, and the height h31 of the third barrier wall part 108 satisfies:

[0183] h31≥(x32-d)*tanα32 Formula (5)

[0184] Wherein, x32 is the distance between the side of the third barrier wall 108 close to the first sub-pixel unit y1 and the side of the second sub-pixel unit y2 away from the third barrier wall 108. a32 is the included angle between the fourth connecting line k4 and the display surface 101a, the fourth connecting line k4 is the connecting line of the edge of the second sub-pixel unit y2 away from the third barrier wall 108 and the other light control unit 1021 (such as the fourth light control unit 1021d) of the light control unit 1021 (such as the third light control unit 1021c) close to the first sub-pixel unit y1. d is the width of the third barrier wall 108.

[0185] In the case of known x31, x32, a31 and a32, the height h31 of the third barrier wall 108 can be determined according to the above formula (4) and formula (5) in the embodiment of the application. The third barrier wall 108 thus determined will not affect the light emitted by the plurality of sub-pixel units 101211 close to the fourth pixel island 1012d in the current third pixel island 1012c to the third light control unit 1021c, and can block the light emitted by the plurality of sub-pixel units 101211 close to the fourth pixel island 1012d in the fourth pixel island 1012d to the fourth light control unit 1021d, avoiding the influence of the light of the third pixel island 1012c on the light control of the fourth light control unit 1021d.

[0186] In the embodiment of the application, the top end of the third barrier wall 108 close to the fifth pixel island 1012e between the plurality of sub-pixel units 101211 close to the fifth pixel island 1012e in the third pixel island 1012c is lower than the fifth connecting line k5, which can refer to the above-mentioned design that the top end of the third barrier wall 108 close to the fourth pixel island 1012d between the plurality of sub-pixel units 101211 close to the fourth pixel island 1012d in the third pixel island 1012c is lower than the third connecting line k3. Similarly, the top end of the third barrier wall 108 close to the fourth pixel island 1012d between the plurality of sub-pixel units 101211 close to the fifth pixel island 1012e in the third pixel island 1012c is higher than the sixth connecting line k6, which can refer to the above-mentioned design that the top end of the third barrier wall 108 close to the fifth pixel island 1012e between the plurality of sub-pixel units 101211 close to the fourth pixel island 1012d in the third pixel island 1012c is higher than the fourth connecting line k4. The embodiment of the application will not be described here.

[0187] In the embodiment of the present application, since the plurality of sub-pixel units 101211 in the third pixel island 1012c are located at different positions in the fourth direction F4, the angle (a31) between the third connecting line k3 formed by the two adjacent and different sub-pixel units 101211 and the display surface 101a is different, and the angle (a32) between the fourth connecting line k4 formed by the two adjacent and different sub-pixel units 101211 and the display surface 101a is also different.

[0188] Similarly, since the plurality of sub-pixel units 101211 in the third pixel island 1012c are located at different positions in the fourth direction F4, the angle between the fifth connecting line k5 formed by the two adjacent and different sub-pixel units 101211 and the display surface 101a is different, and the angle between the sixth connecting line k6 formed by the two adjacent and different sub-pixel units 101211 and the display surface 101a is also different.

[0189] That is, the height of the third barrier wall part 108 actually needs to be different between any two adjacent sub-pixel units 101211, but in order to improve the uniformity of the product, the height of each third barrier wall part 108 can be the same. For example, the height of each third barrier wall part 108 can be the same height in the range determined according to the above formula (4) and formula (5).

[0190] Alternatively, the height h31 of the third barrier wall part 108 between any two adjacent sub-pixel units in the plurality of sub-pixel units on the side of the third pixel island 1012c close to the fourth pixel island 1012d can be designed as h31=x31*tan a31 and h31=(x32-d)*tan a32. That is, x31*tan a31=(x32-d)*tan a32.

[0191] In order to ensure that the light of any sub-pixel unit 101211 can irradiate the corresponding light control unit 1021 and not irradiate other light control units 1021 when the height of the third barrier wall part 108 is a fixed height, the setting position of the third barrier wall part 108 between the two adjacent sub-pixel units 101211 can be changed.

[0192] Alternatively, referring to Figure 23For example, the first sub-pixel unit y1, the second sub-pixel unit y2, the third sub-pixel unit y3 and the fourth sub-pixel unit y4 in the plurality of sub-pixel units 101211 located at one side of the fourth pixel island 1012d close to the third pixel island 1012c are taken as an example. The first sub-pixel unit y1, the second sub-pixel unit y2, the third sub-pixel unit y3 and the fourth sub-pixel unit y4 are respectively the first sub-pixel unit y1, the second sub-pixel unit y2, the third sub-pixel unit y3 and the fourth sub-pixel unit y4 close to the first arrangement edge in the plurality of sub-pixel units 101211 arranged along the fourth direction F4. It can be understood that the third barrier wall part 108 is also arranged between the second sub-pixel unit y2 and the third sub-pixel unit y3.

[0193] It is assumed that the third barrier wall part 108 between the first sub-pixel unit y1 and the second sub-pixel unit y2 is called the first third barrier wall part 108a, and the third barrier wall part 108 between the third sub-pixel unit y3 is called the second third barrier wall part 108b. The included angle α31 between the first third barrier wall part 108a and the third light control unit 1021c close to the fifth light control unit 1021e edge connecting line (the first third connecting line k31) and the display surface 101a is smaller than the included angle α31' between the third sub-pixel unit y3 close to the first third barrier wall part 108a edge and the third light control unit 1021c close to the fifth light control unit 1021e edge connecting line (the second third connecting line k32) and the display surface 101a. And, the included angle α32 between the second sub-pixel unit y2 far from the edge of the first third barrier wall part 108a and the fourth light control unit 1021d close to the third light control unit 1021c edge connecting line (the first fourth connecting line k41) and the display surface 101a is greater than the included angle α32' between the fourth sub-pixel unit 101211 far from the edge of the second third barrier wall part 108b and the fourth light control unit 1021d close to the third light control unit 1021c edge connecting line (the second fourth connecting line k42) and the display surface 101a.

[0194] Similarly, it can be deduced that the plurality of sub-pixel units 101211 located on the side of the third pixel island 1012c close to the fourth pixel island 1012d gradually increase the included angle between the third connecting line k3 formed by the plurality of sub-pixel units 101211 and the display surface 101a and gradually decrease the included angle between the fourth connecting line k4 formed by the plurality of sub-pixel units 101211 and the display surface 101a as the plurality of sub-pixel units 101211 are closer to the center of the third pixel island 1012c. Furthermore, it can be understood that, for the plurality of sub-pixel units 101211 located on the side of the third pixel island 1012c close to the fourth pixel island 1012d, if the setting positions of the third barrier portions 108 at different positions between the adjacent two sub-pixel units 101211 are unchanged, the height of the third barrier portion 108 closer to the center of the third pixel island 1012c can be higher. In the case where the heights of the third barrier portions 108 at different positions are unchanged, the third barrier portion 108 closer to the center of the third pixel island 1012c can be closer to the one of the adjacent two sub-pixel units 101211 away from the center of the third pixel island 1012c. That is, x31 gradually decreases and x32 can gradually increase.

[0195] Similarly, it can be deduced that the plurality of sub-pixel units 101211 located on the side of the third pixel island 1012c close to the fifth pixel island 1012e gradually increase the included angle between the fifth connecting line k5 formed by the plurality of sub-pixel units 101211 and the display surface 101a and gradually decrease the included angle between the sixth connecting line k6 formed by the plurality of sub-pixel units 101211 and the display surface 101a as the plurality of sub-pixel units 101211 are closer to the center of the third pixel island 1012c. Furthermore, it can be understood that, for the plurality of sub-pixel units 101211 located on the side of the third pixel island 1012c close to the fifth pixel island 1012e, if the setting positions of the third barrier portions 108 at different positions between the adjacent two sub-pixel units 101211 are unchanged, the height of the third barrier portion 108 closer to the center of the third pixel island 1012c can be higher. In the case where the heights of the third barrier portions 108 at different positions are unchanged, the third barrier portion 108 closer to the center of the third pixel island 1012c can be farther away from the one of the adjacent two sub-pixel units 101211 closer to the center of the third pixel island 1012c.

[0196] Supposing that the heights of the third barrier portions 108 are calculated by the above formula (4) and formula (5), the distance between the third barrier portion 108 and the target sub-pixel unit between the adjacent sub-pixel units 101211 included in the plurality of sub-pixel units 101211 in the third pixel island 1012c can gradually decrease as the target direction W gradually decreases. The target sub-pixel unit refers to the one of the adjacent two sub-pixel units 101211 close to the fourth pixel island 1012d, and the target direction W can be the direction in which the fourth pixel island 1012d points to the fifth pixel island 1012e.

[0197] Optionally, the third barrier wall portion 108 can be arranged at a position such that the height of the third barrier wall portion 108 is just enough to satisfy the included angle between the third light transmission line k3 or the fifth light transmission line k5 and the display surface 101a, and is just enough to satisfy the included angle between the fourth light blocking line k4 or the sixth light blocking line k6 and the display surface 101a.

[0198] In the embodiment of the present application, the distance x33 between the side of the third barrier wall portion 108 far away from the fifth pixel island 1012e and the side of the one of the two sub-pixel units 101211 far away from the fifth pixel island 1012e and close to the fifth pixel island 1012e can be determined according to the height of the third barrier wall portion 108.

[0199] Optionally, referring to Figure 24 The third barrier wall portion 108 between the two sub-pixel units 101211 of the third pixel island 1012c closest to the fifth pixel island 1012e is referred to as a third third barrier wall portion 108c. The third third barrier wall portion 108c is arranged at a position such that the height h31 of the third third barrier wall portion 108c is less than the distance between the edge of the one of the nearest sub-pixel units 101211 close to the third third barrier wall portion 108c and the edge of the third light control unit 1021c close to the fourth light control unit 1021d along the fifth light transmission line k5, and is greater than or equal to the distance between the edge of the one of the nearest sub-pixel units 101211 far away from the third third barrier wall portion 108c and the edge of the fifth light control unit 1021e close to the third light control unit 1021c along the sixth light blocking line k6.

[0200] Therefore, the distance x33 can satisfy:

[0201]

[0202] wherein α33 is the included angle between the sixth light blocking line k6 and the display surface 101a, d pixel The width of the sub-pixel unit 101211 can be referred to as d.

[0203] Further, the period size P d satisfies:

[0204]

[0205] wherein, in the above formula (7), P pixel is a periodic size between two adjacent sub-pixel units 101211 of the plurality of sub-pixel units 101211 arranged along the fourth direction F4, and Q is a number of the plurality of sub-pixel units 101211 arranged along the fourth direction F4. x33 is a distance between a side of the third barrier portion 108 close to the Q-1th sub-pixel unit 101211 and a side of the Q-1th sub-pixel close to the third barrier portion 108. Wherein, the Q-1th sub-pixel unit 101211 and the Qth sub-pixel unit 101211 are respectively a second sub-pixel unit y2 and a first sub-pixel unit y1 close to a second arrangement edge of the plurality of sub-pixel units 101211 arranged along the fourth direction F4. Wherein, the first arrangement edge and the second arrangement edge can be respectively edges of two ends of the plurality of sub-pixel units 101211 arranged. Alternatively, the second arrangement edge can be an edge of the plurality of sub-pixel units 101211 close to the fifth pixel island 1012e in the third pixel island 1012c.

[0206] In the embodiments of the present application, the first barrier portion 106 and the second barrier portion 107 can be barrier portions between pixel islands, and the third barrier portion 108 can be a barrier portion within a pixel island. Since the spacing between pixel islands is greater than the spacing between sub-pixel units 101211 within a pixel island, the width of the first barrier portion 106 and the second barrier portion 107 can be greater than the width of the third barrier portion 108.

[0207] Alternatively, the width of the first barrier portion 106 and the second barrier portion 107 can range from 0.5 mm (millimeter) to 10 mm, such as 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, and 9 mm, etc. The width of the third barrier portion 108 can range from 10 μm (micrometer) to 100 μm, such as 20 μm, 30 μm, 40 μm, 50 μm, 60 μm, 70 μm, 80 μm, and 90 μm, etc.

[0208] Alternatively, the third barrier portion 108 within a pixel island can be a barrier portion between sub-pixel units 101211 within a pixel island, or a barrier portion on both sides of a pixel island. For example, referring to Figure 21The third barrier wall portion 108 is arranged on one side of the one sub-pixel unit 1012 11 of the third pixel island 1012c closest to the fourth pixel island 1012d. The third barrier wall portion 108 is arranged on one side of the one sub-pixel unit 1012 11 of the third pixel island 1012c closest to the fifth pixel island 1012e. That is, two third barrier wall portions 108 are arranged on both sides of the whole of the sub-pixel units 1012 11 in the third pixel island 1012c.

[0209] The embodiments of the present application can separately arrange the barrier wall portions between the pixel islands, separately arrange the barrier wall portions in the pixel islands, or simultaneously arrange the barrier wall portions between the pixel islands and the barrier wall portions in the pixel islands. The embodiments of the present application do not limit this.

[0210] In the embodiments of the present application, referring to Figure 25 The light-emitting device layer b2 can include, in sequence from the direction away from the substrate substrate 1011, an anode layer b21, a pixel definition layer b22, a light-emitting layer b23, and a cathode layer b24. The material of the pixel definition layer b22 can be a light-blocking material, for example, a black light-blocking material.

[0211] Optionally, the anode layer b21 includes a plurality of anode patterns, the pixel definition layer b22 includes a pixel definition main body portion b221 and a third barrier wall portion 108 on one side of the pixel definition main body portion b221 away from the substrate substrate. The orthographic projection of the third barrier wall portion 108 on the substrate substrate 1011 is located in the orthographic projection of the pixel definition main body portion b221 on the substrate substrate 1011, and the area of the orthographic projection of the third barrier wall portion 108 on the substrate substrate 1011 is smaller than the area of the orthographic projection of the pixel definition main body portion b221 on the substrate substrate 1011. The pixel definition main body portion includes a plurality of hollow regions, each of which exposes at least part of the anode pattern, the light-emitting layer includes a plurality of light-emitting patterns, the light-emitting patterns are connected through the hollow regions and the anode patterns, and the cathode layer b24 is connected with the light-emitting patterns.

[0212] Since the material of the pixel definition layer b22 is a light-blocking material, the third barrier wall portion 108 is arranged as part of the pixel definition layer, so that the third barrier wall portion 108 can block light. Optionally, the pixel definition layer can be prepared by using a halftone mask (HTF).

[0213] In summary, the display unit provided by the embodiments of the present application includes a display device, an angle customization lens located at the display surface of the display device, and a light control device. Since the display unit includes the angle customization lens which can converge the light emitted by the display device, the angle range of the light passing through the angle customization lens and entering the light control device can be small, so that the light control device can control the light in a small range, ensure the light control effect of the light control device, and improve the display effect of the display unit.

[0214] Figure 26 is a structural schematic diagram of a spliced display device provided by the embodiments of the present application. Figure 27 is a structural schematic diagram of another spliced display device provided by the embodiments of the present application. Referring to Figure 26 and Figure 27 The spliced display device 00 includes a display side 00a and a non-display side 00b, and the display side 00a can be used to display images. The spliced display device 00 includes a plurality of display units 100 as described in the above embodiments. The display surfaces 101a of the plurality of display devices 101 all face the display side 00a, and the non-display surfaces 101b of the plurality of display devices 101 all face the non-display side 00b.

[0215] Figure 28 is a schematic diagram of the display surfaces of a plurality of display devices provided by the embodiments of the present application. Referring to Figure 28 It can be seen that the plurality of display units 100 can be arranged in an array in a fifth direction F5 and a sixth direction F6, and the fifth direction F5 and the sixth direction F6 intersect.

[0216] Among them, referring to Figure 26 The display side of the spliced display device 00 formed by splicing the plurality of display units 100 is a plane, that is, the spliced display device 00 can be a flat spliced display device. Alternatively, referring to Figure 27 The display side of the spliced display device 00 formed by splicing the plurality of display units 100 is a curved surface, that is, the spliced display device 00 can be a curved spliced display device.

[0217] Optionally, referring to Figure 27 In the case where the spliced display device 00 is a curved spliced display device, the fifth direction F5 can be an arc line, and the sixth direction F6 can be a straight line, so that the spliced display device 00 formed by the plurality of display units 100 is a curved surface column type display device. The display side 00a of the spliced display device 00 formed by the display surfaces 101a of the plurality of display units 100 of the spliced display device 00 is a curved surface. Optionally, the normal line of the surface close to the display surface 101a of each display unit can point to the curvature center axis of the curved surface. Figure 27 The normal lines of the surfaces close to the display surfaces 101a of the three display units 100 are schematically shown by dashed lines.

[0218] Optionally, the length of the orthographic projection of the curved tiled display device on the reference plane S along the seventh direction F7 is less than the arc length of the curved tiled display device along the fifth direction F5. The reference plane S is parallel to the sixth direction F6 and parallel to the line between the two boundaries of the curved tiled display device at the two ends of the fifth direction F5. The seventh direction F7 is parallel to the reference plane S and perpendicular to the sixth direction F6.

[0219] Since the length of the orthographic projection of the curved tiled display device on the reference plane S along the seventh direction F7 is less than the arc length of the curved tiled display device along the fifth direction F5, the curved tiled display device can occupy a smaller width, and thus the eyebox at the edge can be reduced. When a user watches from a larger distance, the viewing distance and viewing angle of the edge and the middle part are substantially consistent, and the viewing effect is ensured.

[0220] Reference Figure 28 The plurality of display units 100 includes a plurality of display unit groups 100z arranged along the fifth direction F5, and each display unit group 100z includes a plurality of display units 100 arranged along the sixth direction F6. The plurality of display units 100 included in each display unit group 100z are coplanar on one side close to the display surface 101a. That is, the plurality of display units 100 included in each display unit group 100z are on the same plane on one side close to the display surface 101a. The plurality of display units 100 on one side close to the display surface 101a in any two adjacent display unit groups 100z in the plurality of display unit groups 100z intersect. That is, the plurality of display units 100 on one side close to the display surface 101a in the adjacent two display unit groups 100z are on different planes. It should be understood that, Figure 28 In order to facilitate understanding, a gap is drawn between each display unit group 100z, which may not actually exist.

[0221] In the embodiment of the present application, the radius of curvature of the arc surface formed by the side of the display unit 100 close to the non-display surface 101b in the plurality of display unit groups 100z is greater than the radius of curvature of the arc surface formed by the side of the display unit 100 close to the display surface 101a in the plurality of display unit groups 100z. That is, the middle part of the display side 00a of the tiled display device 00 is concave towards the non-display side 00b.

[0222] Since the display side 00a of the tiled display device 00 is curved after the array arrangement of the plurality of display units 100, the viewing angle at any position can be smaller compared to the case where the display side 00a is flat, which can make the tiled display device 00 better adapt to different viewing angles, and thus the tiled display device 00 can obtain better display effect.

[0223] In the embodiments of the present application, the angle between the side of the display unit 100 in the display unit group 100z close to the display surface 101a and the reference plane S can gradually increase as the distance between the display unit group 100z and the second median axis m of the spliced display device 00 increases. The second median axis m extends along the sixth direction F6.

[0224] Optionally, the smaller the distance between the display unit group 100z and the second median axis m, the smaller the angle between the side of the display unit 100 in the display unit group 100z close to the display surface 101a and the reference plane S; the greater the distance between the display unit group 100z and the second median axis m, the greater the angle between the side of the display unit 100 in the display unit group 100z close to the display surface 101a and the reference plane S.

[0225] In the embodiments of the present application, the reference Figure 28 , the plurality of display unit groups 100z can include a plurality of first display unit groups 100z1, a plurality of second display unit groups 100z2 and at least one third display unit group 100z3. The at least one third display unit group 100z3 is located between the plurality of first display unit groups 100z1 and the plurality of second display unit groups 100z2. That is, the first display unit group 100z1 is farther away from the second median axis m than the third display unit group 100z3, and the second display unit group 100z2 is farther away from the second median axis m than the third display unit group 100z3.

[0226] Optionally, the plurality of first display unit groups 100z1 and the plurality of second display unit groups 100z2 are symmetrically arranged relative to the second median axis m of the spliced display device 00. Alternatively, it can be understood that the number of first display unit groups 100z1 can be the same as the number of second display unit groups 100z2, and the plurality of first display unit groups 100z1 and the plurality of second display unit groups 100z2 are symmetrically arranged one by one.

[0227] Optionally, the at least one third display unit group 100z3 is symmetrically arranged relative to the second median axis m of the spliced display device 00. That is, the plurality of display unit groups 100z of the spliced display device 00 are symmetrically arranged relative to the second median axis m, so that the display uniformity of the two parts of the spliced display device 00 located on both sides of the second median axis m is better.

[0228] As a possible case, the reference Figure 28When the number of the plurality of display unit groups 100z included in the plurality of display units 100 is an odd number, the plurality of display unit groups 100z can include one third display unit group 100z3 in which the display surfaces 101a of the plurality of display units 100 are parallel to the reference plane S. The second median axis m is a median axis of the plurality of display units 100 in the third display unit group 100z3 extending in the sixth direction F6.

[0229] Optionally, the side of the display unit 100 in the first display unit group 100z1 close to the display surface 101a and the reference plane S have an acute angle and an obtuse angle, and the acute angle and the obtuse angle are complementary. The acute angle between the first display unit group 100z1 and the reference plane S is closer to the third display unit group 100z3 than the obtuse angle between the first display unit group 100z1 and the reference plane S.

[0230] Optionally, the angle (herein referred to as the acute angle, and the acute angle is indicated in the following text unless otherwise specified) between the side of the display unit 100 in the first display unit group 100z1 close to the display surface 101a and the reference plane S gradually increases in an arithmetic progression as the distance between the first display unit group 100z1 and the second median axis m of the tiled display device 00 increases.

[0231] Optionally, the side of the display unit 100 in the second display unit group 100z2 close to the display surface 101a and the reference plane S have an acute angle and an obtuse angle, and the acute angle and the obtuse angle are complementary. The acute angle between the second display unit group 100z2 and the reference plane S is closer to the third display unit group 100z3 than the obtuse angle between the second display unit group 100z2 and the reference plane S. Optionally, the acute angle between the side of the display unit 100 in each second display unit group 100z2 close to the display surface 101a and the reference plane S is the same as the acute angle between the side of the display unit 100 in the corresponding first display unit group 100z1 close to the display surface 101a and the reference plane S.

[0232] Optionally, the angle (herein also referred to as the acute angle) between the side of the display unit 100 in the second display unit group 100z2 close to the display surface 101a and the reference plane S gradually increases in an arithmetic progression as the distance between the second display unit group 100z2 and the second median axis m of the tiled display device increases.

[0233] Assuming that the plurality of display units 100 comprises N display unit groups 100z, and N is an odd number, and the acute angle between one first display unit group 100z1 farthest from the second median axis m of the N display unit groups 100z and the reference plane S is θ, the acute angles between the plurality of first display unit groups 100z1 arranged in turn in the direction away from the second median axis m and the reference plane S are in turn wherein, i is used to represent the i-th first display unit group 100z1 of the plurality of first display unit groups 100z1 arranged in turn in the direction away from the second median axis m.

[0234] Therefore, the common difference of the acute angle between the side of the display unit 100 close to the display surface 101a and the reference plane S in the plurality of first display unit groups 100z1 can be

[0235] Correspondingly, the acute angle between one second display unit group 100z2 farthest from the second median axis m of the N display unit groups 100z and the reference plane S is θ, and the acute angles between the plurality of second display unit groups 100z2 arranged in turn in the direction away from the second median axis m and the reference plane S are in turn wherein, j is used to represent the j-th second display unit group 100z2 of the plurality of second display unit groups 100z2 arranged in turn in the direction away from the second median axis m. Wherein, j is equal to i.

[0236] Therefore, the common difference of the acute angle between the side of the display unit 100 close to the display surface 101a and the reference plane S in the plurality of second display unit groups 100z2 can be

[0237] For example, referring to Figure 27 and Figure 28 , assuming that the plurality of display units 100 comprises 11 display unit groups 100z, i.e. N = 11, and the acute angle between one first display unit group 100z1 farthest from the second median axis m of the 11 display unit groups 100z and the reference plane S is θ, the acute angles between the plurality of first display unit groups 100z1 arranged in turn in the direction away from the second median axis m and the reference plane S are in turn That is, the common difference of the acute angle between the side of the display unit 100 close to the display surface 101a and the reference plane S in the plurality of first display unit groups 100z1 can be

[0238] Correspondingly, the acute angle between the plurality of second display unit groups 100z2 arranged in sequence in the direction away from the second central axis m and the reference plane S is in sequence That is, the common difference of the arithmetic sequence of the acute angle between the side of the display unit close to the display surface 101a and the reference plane S in the plurality of second display unit groups 100z2 can be

[0239] As another possible case, referring to Figure 29 and Figure 30 The number of the plurality of display unit groups 100z included in the plurality of display units 100 is even, and the plurality of display unit groups 100z can include two third display unit groups 100z3, the display surface 101a of the plurality of display units 100 in the two third display unit groups 100z3 intersects the reference plane S. The second central axis m is located between the two third display unit groups 100z3.

[0240] Optionally, the first third display unit group 100z31 of the two third display unit groups 100z3 is arranged close to the plurality of first display unit groups 100z1, and the second third display unit group 100z32 is arranged close to the plurality of second display unit groups 100z2.

[0241] Optionally, the side of the display unit 100 close to the display surface 101a in the first third display unit group 100z31 and any display unit group 100z of the plurality of first display unit groups 100z1 has an acute angle and an obtuse angle with the reference plane S, and the acute angle and the obtuse angle are complementary. The acute angle between any display unit group 100z and the reference plane S is closer to the second central axis m than the obtuse angle between the display unit group 100z and the reference plane S.

[0242] Optionally, the angle between the display surface 101a of the display device 101 in the first third display unit group 100z31 and the reference plane S gradually increases in an arithmetic sequence as the distance between the display unit group 100z and the second central axis m of the 3D display device increases.

[0243] Optionally, the side of the display unit 100 close to the display surface 101a in the second third display unit group 100z32 and the plurality of second display unit groups 100z2 has an acute angle and an obtuse angle with the reference plane S, and the acute angle and the obtuse angle are complementary. The acute angle between any display unit group 100z and the reference plane S is closer to the second central axis m than the obtuse angle between the display unit group 100z and the reference plane S.

[0244] Optionally, the acute angle between the side of the display unit 100 close to the display surface 101a and the reference plane S in each second display unit group 100z2 is the same as the acute angle between the side of the display unit 100 close to the display surface 101a and the reference plane S in the corresponding first display unit group 100z1, the acute angle between the side of the display unit 100 close to the display surface 101a and the reference plane S in the first third display unit group 100z31 is the same as the acute angle between the side of the display unit 100 close to the display surface 101a and the reference plane S in the second third display unit group 100z32.

[0245] Optionally, the angles between the side of the display unit 100 close to the display surface 101a and the reference plane S in the second third display unit group 100z32 and the plurality of second display unit groups 100z2 gradually increase in an arithmetic progression as the distance between the display unit group 100z and the second central axis m increases.

[0246] Supposing that the plurality of display unit groups 100z include N display unit groups 100z, and N is an even number, the acute angle between the first display unit group 100z1 farthest from the second central axis m and the reference plane S is θ, the acute angles between the plurality of first display unit groups 100z1 and the third display unit groups 100z3 arranged in turn in the direction away from the second central axis m and the reference plane S are in turn wherein, i is used to represent the i-th display unit group 100z in the plurality of first display unit groups 100z1 and the first third display unit group 100z31 arranged in turn in the direction away from the second central axis m.

[0247] Thus, the common difference of the arithmetic progression of the acute angles between the display surface 101a of the display device 101 and the reference plane S in the first third display unit group 100z31 and the plurality of first display unit groups 100z1 can be

[0248]

[0249] Correspondingly, the acute angle between the second display unit group 100z2 farthest from the second central axis m and the reference plane S in the N display unit groups 100z is θ, the acute angles between the plurality of second display unit groups 100z2 and the second third display unit group 100z32 arranged in turn in the direction away from the second central axis m and the reference plane S are in turn wherein, j is used to represent the jth display unit group 100z in the second third display unit group 100z32 and the plurality of second display unit groups 100z2 arranged in sequence along the direction away from the second central axis m. Wherein, j is equal to i.

[0250] Thus, the tolerance of the arithmetic sequence of the acute angle between the side of the display unit 100 close to the display surface 101a and the reference plane S in the second third display unit group 100z32 and the plurality of second display unit groups 100z2 can be

[0251] For example, referring to Figure 29 and Figure 30 , assuming that the plurality of display unit groups 100 includes 12 display unit groups 100z, i.e. N = 12, and the acute angle between the first display unit group 100z1 farthest from the second central axis m and the reference plane S is θ, the acute angle between the first third display unit group 100z31 and the reference plane S arranged in sequence along the direction away from the second central axis m can be That is, the tolerance of the arithmetic sequence of the acute angle between the side of the display unit 100 close to the display surface 101a and the reference plane S in the first third display unit group 100z31 and the plurality of first display unit groups 100z1 can be

[0252] Correspondingly, the acute angle between the second third display unit group 100z32 and the reference plane S arranged in sequence along the direction away from the second central axis m can be That is, the tolerance of the arithmetic sequence of the acute angle between the side of the display unit 100 close to the display surface 101a and the reference plane S in the second third display unit group 100z32 and the plurality of second display unit groups 100z2 can be

[0253] As a first optional implementation, referring to Figure 6 , the third direction F3, the first direction F1 and the sixth direction F6 are parallel to each other, and the second direction F2 and the fourth direction F4 are parallel. That is, the arrangement direction of the sub-pixel group 10121z in the pixel unit 10121 of the pixel island 1012, the extension direction of the sub-pixel unit 101211, and the arrangement direction of the plurality of display units 100 in the display unit group 100z are parallel to each other.

[0254] Referring to Figure 31, assuming that the viewing space in the direction perpendicular to the sixth direction F6 and parallel to the display surface 101a (for example, the horizontal direction) when the display unit 100 is not rotated is L1, then the reference Figure 32 , when the display unit is rotated by 100 degrees Afterwards, the viewing space of the display unit 100 in the horizontal direction can be expanded to L2. The viewing space of the display unit 100 in the horizontal direction after rotation can be 1 / 4 of the viewing space of the display unit 100 in the horizontal direction before rotation. That is, by rotating the display unit 100, the viewing space of the display unit 100 in the horizontal direction can be increased. Figure 31 and Figure 32 The g in is used to represent the pupil distance of the human eye in the horizontal direction. The range can be 0° to 360°.

[0255] In order to expand the viewing space of the display unit in the horizontal direction, the following second optional implementation manner and third optional implementation manner may be included:

[0256] As a second optional implementation, refer to Figure 33 , Figure 34 and Figure 35 , the extension direction of the sub-pixel unit 101211 is tilted, and the extension direction of the light control unit 1021 is also tilted. The tilt angle of the sub-pixel unit 101211 can be the same as the tilt angle of the light control unit 1021. The first direction F1 and the sixth direction F6 intersect. Figure 34 yes Figure 33 Schematic diagram of pixel islands in . Figure 35 yes Figure 34 Schematic diagram of area B.

[0257] Optionally, one of the third direction F3 and the fourth direction F4 may be parallel to the sixth direction F6. Figures 33 to 35 For example, the fourth direction F4 is parallel to the sixth direction F6, and the third direction F3 is perpendicular to the sixth direction F6. In this case, the second direction F2, the third direction F3, and the fourth direction F4 all intersect. Figure 33 In the illustrated solution, the grey solid line represents the contour line of the light control unit 1021 in the long side direction, and the grey dotted line represents the central axis of the light control unit 1021 along the long side direction.

[0258] In the first and second implementations above, Figure 33 Can be used to represent a display device 101, or Figure 33The display device 101 can be one of a plurality of sub-display devices 101v included in the display device 101, and the display device 101 can be formed by splicing a plurality of sub-display devices 101v.

[0259] Referring to Figure 36 In a case where the display device 101 is formed by splicing a plurality of sub-display devices 101v, the plurality of sub-display devices 101v in the display device 101 can be arranged in an array in the third direction F3 and the fourth direction F4. The light-emitting region of the display device 101 can include a first boundary c1 and a second boundary c2 arranged oppositely, and a third boundary c3 and a fourth boundary c4 arranged oppositely. Referring to Figure 36 The first boundary c1 and the second boundary c2 of the display device 101 are parallel to the third direction F3, and the third boundary c3 and the fourth boundary c4 of the display device 101 are parallel to the fourth direction F4.

[0260] Regardless of which of the above two implementations, one of the third direction F3 and the fourth direction F4 is parallel to the sixth direction F6, so that the plurality of sub-display devices 101v included in the display device 101 can be arranged in an array such that two boundaries of the display device 101 formed by the plurality of sub-display devices 101v are parallel to the sixth direction F6. In this way, the splicing of a plurality of display units 100 in the sixth direction F6 in the display unit group 100z including the display device 101 can be facilitated. Further, the splicing display apparatus 00 formed by splicing a plurality of display unit groups 100z can be facilitated to be a display apparatus of a curved surface column type.

[0261] As a third optional implementation, referring to Figure 37 The display device 101 and the light control unit 1021 are arranged in a whole body in an inclined manner. The inclination angle of the display device 101 can be the same as the inclination angle of the light control unit 1021. The third direction F3 is parallel to the first direction F1, and both the third direction F3 and the first direction F1 intersect the sixth direction F6. The second direction F2 is parallel to the fourth direction F4, and both the second direction F2 and the fourth direction F4 intersect the sixth direction F6.

[0262] Optionally, the light emitting region of the display device 101 comprises a first boundary c1 and a second boundary c2 arranged oppositely, and a third boundary c3 and a fourth boundary c4 arranged oppositely. The first boundary c1 and the second boundary c2 of the display device 101 are parallel to the sixth direction F6, and the third boundary c3 and the fourth boundary c4 of the display device 101 are perpendicular to the sixth direction F6. Although the display device 101 and the light control unit 1021 are arranged obliquely as a whole, in order to facilitate the splicing of multiple display units 100 in the display unit group 100z including the display device 101 in the sixth direction F6, two boundaries in the display device 101 can be made parallel to the sixth direction F6, and the other two boundaries can be made perpendicular to the second boundary c2.

[0263] Optionally, the display device 101 comprises a plurality of sub-display devices 101v, and the plurality of sub-display devices 101v are arranged in an array in the third direction F3 and the fourth direction F4. In this case, in order to make the four boundaries of the display device 101 satisfy the above conditions, the display device 101 can comprise a light shielding part 1013. The light shielding part 1013 can cover at least part of the light emitting region of the peripheral part sub-display device 101v of the array structure formed by the plurality of sub-display devices 101v. Figure 38

[0264] Optionally, the light shielding part 1013 comprises a first light shielding part 10131 extending along the sixth direction F6 and a second light shielding part 10132 extending along a direction perpendicular to the sixth direction F6. The first light shielding part 10131 and the second light shielding part 10132 enclose the boundaries of the light emitting region of the display device 101.

[0265] For the third implementation manner, since two boundaries of the light emitting region of the display device 101 are parallel to the sixth direction F6, this can facilitate the splicing of multiple display devices 101 in the display unit group 100z in the sixth direction F6. Furthermore, the spliced display device formed by splicing the multiple display unit groups 100z can be a curved surface column type display device.

[0266] In summary, the embodiments of the present application provide a spliced display device. The display unit comprises a display device, an angle customization lens located at the display surface of the display device, and a light control device. Since the angle customization lens included in the display unit can converge the light emitted by the display device, the angle range of the light after passing through the angle customization lens and entering the light control device can be small, and thus the light control device can control the light in a small range, thereby ensuring the light control effect of the light control device and improving the display effect of the display unit.
