[0002] The display substrate includes a driving backplane and multiple light-emitting components connected to the driving backplane. The driving backplane can provide driving signals to the light-emitting components so that the light-emitting components emit light, thereby realizing the display.

[0003] In related technologies, a light-emitting component includes a substrate and various light-emitting units of different colors located on the substrate. Typically, a first distance between each light-emitting unit and a first boundary of the substrate is different from a second distance between the light-emitting unit and a second boundary of the substrate.

[0004] However, due to the difference between the first distance and the second distance, the symmetry of the light emission brightness of the light-emitting unit on both sides of the light-emitting unit is poor, the uniformity of the brightness of the light-emitting component at different viewing angles is poor, and the display effect of the display substrate is poor.

[0065] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0066] Figure 1 This is a partial structural schematic diagram of a display substrate provided in an embodiment of this application. (Reference) Figure 1 As can be seen, the display substrate 100 includes a driving backplate 101, multiple light-emitting components 102, and a first light-shielding layer 103. Among them, Figure 1 Two light-emitting components 102 are shown. The first light-shielding layer 103 can be referred to as black glue or black film.

[0067] refer to Figure 1The light-emitting component 102 includes a transparent substrate 1021 and a first light-emitting unit 1022 located on the side of the transparent substrate 1021 near the driving back plate 101. Optionally, the transparent substrate 1021 can be glass. The transparent substrate 1021 includes a first side surface 1021a and a second side surface 1021b disposed opposite to each other, and the first side surface 1021a and the second side surface 1021b are arranged along a first direction X. The distance between the first light-emitting unit 1022 and the first side surface 1021a is smaller than the distance between the first light-emitting unit 1022 and the second side surface 1021b. Furthermore, a first light-shielding layer 103 is located at least between adjacent light-emitting components 102, and the first light-shielding layer 103 covers the first side surface 1021a and the second side surface 1021b.

[0068] Since the first light-shielding layer 103 covers the first side 1021a and the second side 1021b, when the light emitted by the first light-emitting unit 1022 shines on the first side 1021a or the second side 1021b, the light cannot be emitted. Therefore, the light emitted by the first light-emitting unit 1022 can only be emitted from the surface of the transparent substrate 1021 away from the first light-emitting unit 1022.

[0069] Because the distance between the first light-emitting unit 1022 and the first side surface 1021a is not equal to the distance between the first light-emitting unit 1022 and the second side surface 1021b, the angle of light emitted from a portion of the surface of the transparent substrate 1021 away from the first light-emitting unit 1022 near the first side surface 1021a differs from the angle of light emitted from a portion of the surface of the transparent substrate 1021 away from the first light-emitting unit 1022 near the second side surface 1021b. This may result in differences in the luminous brightness of the light-emitting component 102 when viewed from two different sides.

[0070] Optionally, when the light emitted by the first light-emitting unit 1022 exits from a portion of the surface of the transparent substrate 1021 away from the first light-emitting unit 1022 and near the second side 1021b (hereinafter referred to as the first light ray near the second side 1021b), the first light-shielding layer 103 has a weaker restriction on the angle of the light, and the brightness attenuation is not severe. When the light emitted by the first light-emitting unit 1022 exits from a portion of the surface of the transparent substrate 1021 away from the first light-emitting unit 1022 and near the first side 1021a (hereinafter referred to as the first light ray near the first side 1021a), the first light-shielding layer 103 has a stronger restriction on the angle of the light, and the brightness attenuation is more severe.

[0071] In this embodiment, to improve the brightness uniformity of the light-emitting component 102 under different viewing angles, it can be achieved by reducing the brightness attenuation of the first light ray near the first side 1021a or increasing the light intensity of the first light ray near the first side 1021a. Optionally, the light-emitting component 102 can satisfy one of the following three conditions to improve the problem of poor brightness uniformity of the light-emitting component 102 under different viewing angles and improve the display effect of the light-emitting component 102.

[0072] Condition 1: The relationship between the thickness H of the transparent substrate 1021 and the distance D1 between the first light-emitting unit 1022 and the first side surface 1021a satisfies: H / D1≤2 。

[0073] refer to Figure 2 With the thickness H of the transparent substrate 1021 fixed, the larger the distance D1 between the first light-emitting unit 1022 and the first side surface 1021a, the greater the angular limitation of the light emitted by the first light-shielding layer 103 on the first light-emitting unit 1022 (e.g., ...). Figure 2 The angle a2 is greater than the angle a1, which can prevent a large amount of light emitted by the first light-emitting unit 1022 from being absorbed by the first light-shielding layer 103, and reduce the brightness attenuation of the first light near the first side 1021a.

[0074] refer to Figure 3 When the distance D1 between the first light-emitting unit 1022 and the first side surface 1021a is a fixed value, the thinner the thickness H of the transparent substrate 1021, the greater the angle of light emitted from the transparent substrate 1021 away from the surface of the first light-emitting unit 1022, thus reducing the angle limitation of the first light-shielding layer 103 on the light emitted from the first light-emitting unit 1022 (e.g., Figure 3 The angle a3 is greater than the angle a1, which can prevent a large amount of light emitted by the first light-emitting unit 1022 from being absorbed by the first light-shielding layer 103, thereby reducing the brightness attenuation of the first light near the first side 1021a.

[0075] That is, in order to reduce the brightness attenuation of the first light ray near the first side 1021a, this can be achieved by increasing the distance D1 between the first light-emitting unit 1022 and the first side 1021a, and by reducing the thickness H of the transparent substrate 1021. For example, a ratio of the thickness H of the transparent substrate 1021 to the distance D1 between the first light-emitting unit 1022 and the first side 1021a to be less than or equal to 2 can ensure the improvement effect on the brightness attenuation of the first light ray from the first side 1021a, thereby improving the problem of poor brightness uniformity of the light-emitting component 102 from different viewing angles and improving the display effect of the light-emitting component 102.

[0076] Condition 2: The first side surface 1021a is inclined relative to the surface of the transparent substrate 1021 facing the first light-emitting unit 1022, and the included angle between the first side surface 1021a and the surface of the transparent substrate 1021 facing the first light-emitting unit 1022 is an obtuse angle. The light-emitting component 102 also includes a first reflective layer F1 covering the first side surface 1021a.

[0077] refer to Figure 4 Because the first side surface 1021a is inclined and is covered by a first reflective layer F1, when the light emitted by the first light-emitting unit 1022 shines on the inclined first side surface 1021a, the light can be reflected by the first reflective layer F1. This allows the light that was originally absorbed by the first light-shielding layer 103 to be emitted from the surface of the transparent substrate 1021 away from the first light-emitting unit 1022, increasing the amount of light from the first light source near the first side surface 1021a. Therefore, the amount of light from the first light source near the first side surface 1021a can be made similar to the amount of light from the first light source near the second side surface 1021b, thereby improving the problem of poor brightness uniformity of the light-emitting component 102 at different viewing angles and enhancing the display effect of the light-emitting component 102.

[0078] Condition 3: The relationship between the thickness H of the transparent substrate 1021 and the distance D1 between the first light-emitting unit 1022 and the first side surface 1021a satisfies: H / D1≤2. Furthermore, the first side surface 1021a is inclined relative to the surface of the transparent substrate 1021 facing the first light-emitting unit 1022, and the angle between the first side surface 1021a and the surface of the transparent substrate 1021 facing the first light-emitting unit 1022 is an obtuse angle. The light-emitting component 102 also includes a first reflective layer F1 covering the first side surface 1021a.

[0079] In this embodiment, condition 3 can be the union of conditions 1 and 2. That is, the ratio of the thickness H of the transparent substrate 1021 to the distance D1 between the first light-emitting unit 1022 and the first side surface 1021a is less than or equal to 2, which ensures the improvement effect on the brightness attenuation of the light from the first side surface 1021a. At the same time, the first side surface 1021a can be tilted and covered with the first reflective layer F1 so that the amount of light from the first light source near the first side surface 1021a is similar to the amount of light from the first light source near the second side surface 1021b. Thus, by reducing the brightness attenuation of the light from the first side surface 1021a and increasing the amount of light from the first side surface 1021a, the problem of poor brightness uniformity of the light-emitting component 102 from different viewing angles can be improved, thereby improving the display effect of the light-emitting component 102.

[0080] In summary, this application provides a display substrate including a driving backplate, multiple light-emitting components, and a first light-shielding layer. The ratio of the thickness of the transparent substrate in the light-emitting component to the distance between the first light-emitting unit and the first side surface is less than or equal to 2, thereby reducing the brightness attenuation of the first light rays near the first side surface. And / or, the first side surface is designed at an angle and covered with a first reflective layer to increase the light intensity of the first side surface, thereby making the light intensity of the first light rays near the first side surface and the light intensity of the first light rays near the second side surface similar. This improves the problem of poor brightness uniformity of the light-emitting components at different viewing angles, enhancing the display effect of the display substrate.

[0081] Optionally, the first light-shielding layer 103 includes a first portion located between adjacent light-emitting components 102, and a second portion located on the side of the light-emitting component 102 away from the driving backplate 101. The first and second portions are continuously distributed. This ensures that both the side surface of the light-emitting component and the surface away from the driving backplate have the first light-shielding layer 103, thus guaranteeing a consistent ink color on the display substrate.

[0082] Optionally, the portion of the first light-shielding layer 103 located on the side of the light-emitting component 102 away from the driving backplate 101 is at least light-transmitting, or the portion of the first light-shielding layer 103 located on the side of the light-emitting component 102 away from the driving backplate 101 has a certain transmittance. This can prevent the light-emitting effect of the light-emitting component 102 from being affected by the setting of the first light-shielding layer 103.

[0083] In this embodiment, the thickness H of the transparent substrate 1021 and the distance D1 between the first light-emitting unit 1022 and the first side surface 1021a can be less than or equal to 4 / 3, i.e., H / D1≤4 / 3. By further reducing the ratio of the thickness H of the transparent substrate 1021 to the distance D1 between the first light-emitting unit 1022 and the first side surface 1021a, the brightness attenuation of the first light near the first side surface 1021a can be further reduced.

[0084] Taking a transparent substrate 1021 with a thickness H of 80 μm as an example, the curves showing the change in luminance as a function of viewing angle when different distances D1 are selected are obtained. (Reference) Figure 5 It can be seen that when the distance D1 is 60 μm, the curve of the emission brightness changing with the viewing angle is symmetrical with respect to the 0 viewing angle. Furthermore, when the distance D1 is further increased to 70 μm or 80 μm, the curve of the emission brightness changing with the viewing angle is symmetrical with respect to the 0 viewing angle, and the curve hardly changes. Figure 5 In the figure, the curves of luminous intensity change with viewing angle at distances of 70 μm and 80 μm from D1 coincide.

[0085] Taking a distance D1 of 30 μm as an example, the curves showing the change in luminance as a function of viewing angle for different thicknesses H are obtained. (Reference) Figure 6 It can be seen that when the thickness H of the transparent substrate 1021 is reduced to 40 μm, the curve of the emission brightness changing with the viewing angle is symmetrical with respect to the 0-angle viewing angle. Furthermore, when the thickness H of the transparent substrate 1021 is further reduced to 30 μm or 20 μm, the curve of the emission brightness changing with the viewing angle is symmetrical with respect to the 0-angle viewing angle, and the curve hardly changes. Figure 6 In the figure, the luminous intensity curves of thicknesses H of 40μm, 30μm and 20μm as a function of viewing angle coincide.

[0086] As can be seen from the two examples above, when the ratio of the thickness H of the transparent substrate 1021 to the distance D1 between the first light-emitting unit 1022 and the first side surface 1021a is less than or equal to 4 / 3, the symmetry of the curve of light emission brightness changing with the viewing angle can be improved, thereby improving the brightness uniformity of the light-emitting component 102 at different viewing angles.

[0087] Since the ratio of the thickness H of the transparent substrate 1021 to the distance D1 between the first light-emitting unit 1022 and the first side surface 1021a affects the symmetry of the curve of light emission brightness changing with the viewing angle, when the ratio of thickness H to distance D1 is less than or equal to 2, the distance D1 between the first light-emitting unit 1022 and the first side surface 1021a can be reduced by thinning the thickness H of the transparent substrate 1021, thereby increasing the utilization rate of the transparent substrate 1021. In other words, reducing the thickness H of the transparent substrate 1021 is more conducive to improving the utilization rate of the transparent substrate 1021.

[0088] Optionally, the thickness of the transparent substrate 1021 can range from 20 μm to 700 μm. Since thinning the transparent substrate 1021H is more conducive to improving the utilization rate of the transparent substrate 1021, the thickness of the transparent substrate 1021 can further range from 20 μm to 80 μm, for example, the thickness of the transparent substrate 1021 can be 30 μm, 35 μm, 40 μm, 45 μm, 50 μm, 60 μm and 70 μm, etc.

[0089] Figure 7 This is a partial structural schematic diagram of another display substrate provided in an embodiment of this application. (Reference) Figure 7 The light-emitting component 102 further includes a second light-emitting unit 1023 located on the side of the transparent substrate 1021 near the driving back plate 101. The first light-emitting unit 1022 and the second light-emitting unit 1023 are arranged along the first direction X, and the distance between the second light-emitting unit 1023 and the second side surface 1021b is smaller than the distance between the second light-emitting unit 1023 and the first side surface 1021a.

[0090] Because the distance between the second light-emitting unit 1023 and the first side surface 1021a is not equal to the distance between the second light-emitting unit 1023 and the second side surface 1021b, the angle of light emitted from a portion of the surface of the transparent substrate 1021 away from the second light-emitting unit 1023 near the first side surface 1021a differs from the angle of light emitted from a portion of the surface of the transparent substrate 1021 away from the second light-emitting unit 1023 near the second side surface 1021b. This may result in differences in the luminous brightness of the light-emitting component 102 when viewed from two different sides.

[0091] Optionally, when the light emitted by the second light-emitting unit 1023 exits from a portion of the surface of the transparent substrate 1021 away from the second light-emitting unit 1023 and near the first side 1021a (hereinafter referred to as the second light near the second side 1021b), the first light-shielding layer 103 has a weaker restriction on the angle of the light, and the brightness attenuation is not severe. When the light emitted by the second light-emitting unit 1023 exits from a portion of the surface of the transparent substrate 1021 away from the second light-emitting unit 1023 and near the second side 1021b (hereinafter referred to as the second light near the first side 1021a), the first light-shielding layer 103 has a stronger restriction on the angle of the light, and the brightness attenuation is more severe.

[0092] Since the light-emitting component 102 includes multiple light-emitting units (such as the first light-emitting unit 1022 and the second light-emitting unit 1023), and the distances between the multiple light-emitting units and the first side 1021a, as well as the distances between the multiple light-emitting units and the second side 1021b, are different, color shift problems are likely to occur when the light emitted by the multiple light-emitting units is mixed.

[0093] For example, the first light ray emitted by the first light-emitting unit 1022 near the first side 1021a is severely attenuated (lower light output), while the first light ray emitted near the second side 1021b is not severely attenuated (higher light output). Similarly, the second light ray emitted by the second light-emitting unit 1023 near the first side 1021a is not severely attenuated (higher light output), while the second light ray emitted near the second side 1021b is severely attenuated (lower light output). Therefore, the color of the light resulting from the mixture of the lower first light ray and the higher second light ray near the first side 1021a differs from the color of the light resulting from the mixture of the higher first light ray and the lower second light ray near the second side 1021b, leading to color shift when the light-emitting component 102 is viewed from different angles.

[0094] To improve the color shift problem, the brightness curve of the first light-emitting unit 1022 can be made approximately symmetrical with respect to the viewing angle, and the brightness curve of the second light-emitting unit 1023 can be made approximately symmetrical with respect to the viewing angle. This will result in better color uniformity after the light emitted by the first light-emitting unit 1022 and the light emitted by the second light-emitting unit 1023 are mixed at different viewing angles.

[0095] The design of the first light-emitting unit 1022 in the light-emitting component 102 can refer to the above embodiments.

[0096] For the second light-emitting unit 1023 in the light-emitting component 102, as an optional implementation, the relationship between the thickness H of the transparent substrate 1021 and the second distance D2 between the second light-emitting unit 1023 and the second side surface 1021b satisfies: H / D2≤2.

[0097] refer to Figure 8 With the thickness H of the transparent substrate 1021 fixed, the larger the distance D2 between the second light-emitting unit 1023 and the second side surface 1021b, the less the angle restriction of the light emitted by the first light-shielding layer 103 on the second light-emitting unit 1023 can be reduced (e.g., Figure 8 The angle b2 is greater than the angle b1, which can prevent a large amount of light emitted by the second light-emitting unit 1023 from being absorbed by the first light-shielding layer 103, thereby reducing the brightness attenuation of the second light near the second side 1021b.

[0098] refer to Figure 9 When the distance D2 between the second light-emitting unit 1023 and the second side surface 1021b is a fixed value, the thinner the thickness H of the transparent substrate 1021, the greater the angle of light emitted from the transparent substrate 1021 away from the surface of the second light-emitting unit 1023, thus reducing the angle limitation of the first light-shielding layer 103 on the light emitted by the second light-emitting unit 1023 (e.g., Figure 9 The angle b3 is greater than the angle b1, which can prevent a large amount of light emitted by the second light-emitting unit 1023 from being absorbed by the first light-shielding layer 103, thereby reducing the brightness attenuation of the second light near the second side 1021b.

[0099] That is, in order to reduce the brightness attenuation of the second light ray near the second side 1021b, this can be achieved by increasing the distance D2 between the second light-emitting unit 1023 and the second side 1021b, and by reducing the thickness H of the transparent substrate 1021. For example, a ratio of the thickness H of the transparent substrate 1021 to the distance D1 between the second light-emitting unit 1023 and the second side 1021b is less than or equal to 2, which can ensure the improvement effect on the brightness attenuation of the second light ray from the second side 1021b, thereby making the curve of the luminous brightness of the second light-emitting unit 1023 changing with the viewing angle approximately symmetrical with respect to the 0-angle viewing angle.

[0100] In this embodiment, the thickness H of the transparent substrate 1021 and the distance D2 between the second light-emitting unit 1023 and the second side surface 1021b can be less than or equal to 4 / 3, i.e., H / D2 ≤ 4 / 3. By further reducing the ratio of the thickness H of the transparent substrate 1021 to the distance D2 between the second light-emitting unit 1023 and the second side surface 1021b, the brightness attenuation of the second light near the second side surface 1021b can be further reduced.

[0101] In this embodiment, the distance D2 between the second light-emitting unit 1023 and the second side surface 1021b can be equal to the distance D1 between the first light-emitting unit 1022 and the first side surface 1021a. This further ensures good color uniformity after the light emitted by the first light-emitting unit 1022 and the light emitted by the second light-emitting unit 1023 are mixed from different viewing angles. Of course, the distance D2 between the second light-emitting unit 1023 and the second side surface 1021b can also be unequal to the distance D1 between the first light-emitting unit 1022 and the first side surface 1021a. This embodiment does not limit this, as long as H / D1≤2 and H / D2≤2 are satisfied.

[0102] Regarding the second light-emitting unit 1023 in the light-emitting component 102, as another optional implementation, refer to... Figure 10 The second side surface 1021b is inclined relative to the surface of the transparent substrate 1021 facing the first light-emitting unit 1022, and the included angle between the second side surface 1021b and the surface of the transparent substrate 1021 facing the first light-emitting unit 1022 is an obtuse angle. The light-emitting component 102 also includes a second reflective layer F2 covering the second side surface 1021b.

[0103] refer to Figure 11Because the second side 1021b is inclined and covered by a second reflective layer F2, when light emitted from the second light-emitting unit 1023 shines on the inclined second side 1021b, the light can be reflected by the second reflective layer F2. This allows light that was originally absorbed by the first light-shielding layer 103 to exit from the surface of the transparent substrate 1021 away from the second light-emitting unit 1023, increasing the amount of light from the second light source near the second side 1021b. Therefore, the amount of light from the second light source near the second side 1021b can be made similar to the amount of light from the second light source near the first side 1021a, thereby improving the problem of poor brightness uniformity of the second light-emitting unit 1023 at different viewing angles.

[0104] It should be noted that the light emitted by the first light-emitting unit 1022 will also illuminate the inclined second side 1021b. However, since the distance between the first light-emitting unit 1022 and the second side 1021b is relatively far, the light emitted by the first light-emitting unit 1022 to the second side 1021b will be attenuated due to the path. Even if the second reflective layer F2 on the second side 1021b can reflect the light from the first light-emitting unit 1022, the amount of light reflected is relatively small due to the light attenuation, and it will not have a significant impact on the light mixing effect.

[0105] In this embodiment of the application, reference is made to Figure 12 When the distance d between the light-emitting unit and the side is fixed, the thicker the transparent substrate 1021 is, the larger the reflection angle α of the side of the transparent substrate 1021 is, and the more light is reflected. This will cause the light emission brightness curve to rise, making it difficult to achieve symmetry.

[0106] For example, when the distance d between the light-emitting unit and the side is 30 μm and the thickness h of the transparent substrate 1021 is 80 μm, the reflection angle α of the side of the transparent substrate 1021 is approximately 69.4°. When the distance d between the light-emitting unit and the side is 30 μm and the thickness h of the transparent substrate 1021 is 40 μm, the reflection angle α of the side of the transparent substrate 1021 is approximately 53.1°.

[0107] Therefore, to avoid an upward tilt in the luminance curve, the thickness of the transparent substrate 1021 can be designed for different conditions. For example, when the thickness of the transparent substrate 1021 is greater than 45 μm, the second side 1021b is designed with an angle and covers the second reflective layer F2, while the first side 1021a can be designed by defining the relationship between the thickness H and the distance D1. That is, when the light-emitting component 102 satisfies condition 1, and the second side 1021b is designed with an angle and covers the second reflective layer F2, the thickness of the transparent substrate 1021 is greater than 45 μm.

[0108] For example, when the thickness of the transparent substrate 1021 is less than or equal to 45 μm, the second side 1021b is designed to be tilted and cover the second reflective layer F2, and the first side 1021a is designed to be tilted and cover the first reflective layer F1. That is, when the light-emitting component 102 satisfies condition 2, and the second side 1021b is designed to be tilted and cover the second reflective layer F2, the thickness of the transparent substrate 1021 is less than or equal to 45 μm.

[0109] In this embodiment, taking a transparent substrate 1021 with a thickness of 40 μm (the first side 1021a is designed with an inclination and covering the first reflective layer F1, and the second side 1021b is designed with an inclination and covering the second reflective layer) as an example, the luminance variation curves of the first light-emitting unit 1022 with the viewing angle at different tilt angles are obtained. The luminance variation curve of the second light-emitting unit 1023 with the viewing angle is similar to that of the first light-emitting unit 1022.

[0110] Wherein, the tilt angle b refers to the included angle between the side of the transparent substrate 1021 away from the driving back plate 101 and either the first side surface 1021a or the second side surface 1021b. In this embodiment, the included angle between the side of the transparent substrate 1021 away from the driving back plate 101 and the first side surface 1021a is equal to the included angle between the side of the transparent substrate 1021 away from the driving back plate 101 and the second side surface 1021b.

[0111] refer to Figure 13 and Figure 14 It can be seen that when the tilt angle is between 90° and 87°, the symmetry of the curve showing the change in luminance with the viewing angle relative to the 0-angle view is poor. When the tilt angle is between 86° and 81°, the symmetry of the curve showing the change in luminance with the viewing angle relative to the 0-angle view is good. That is, when the thickness of the transparent substrate 1021 is 40μm, the tilt angle can be in the range of 81° to 86°.

[0112] In this embodiment, taking a transparent substrate 1021 with a thickness of 45 μm (the first side 1021a is designed with an inclination and covering the first reflective layer F1, and the second side 1021b is designed with an inclination and covering the second reflective layer F2) as an example, the luminance variation curves of the first light-emitting unit 1022 with the viewing angle at different tilt angles are obtained. The luminance variation curve of the second light-emitting unit 1023 with the viewing angle is similar to that of the first light-emitting unit 1022.

[0113] refer to Figure 15It can be seen that when the tilt angle is in the range of 75° to 86°, the curve of the change in luminance with the viewing angle has good symmetry with respect to the 0-angle viewing angle. That is, when the thickness of the transparent substrate 1021 is 45μm, the tilt angle can be in the range of 75° to 86°.

[0114] This application embodiment uses a transparent substrate 1021 with a thickness of 80 μm (the first side 1021a is designed with an inclination and covers the first reflective layer F1, while the second side 1021b does not require special design) as an example to derive the luminance variation curve of the first light-emitting unit 1022 with the viewing angle at different tilt angles. "The second side 1021b does not require special design" means that the second side 1021b can be perpendicular to the surface of the transparent substrate 1021 away from the driving backplate 101, or the second side 1021b can be tilted relative to the surface of the transparent substrate 1021 away from the driving backplate 101, but without covering the reflective layer.

[0115] refer to Figure 16 It can be seen that when the tilt angle is between 90° and 89°, the curve of luminous intensity changing with the viewing angle has poor symmetry relative to the 0-angle due to the brightness attenuation of the first ray near the first side 1021a. When the tilt angle is between 85° and 80°, the curve of luminous intensity changing with the viewing angle has poor symmetry relative to the 0-angle due to the curve curving upwards.

[0116] refer to Figure 17 It can be seen that the curve of luminous intensity changing with the viewing angle is relatively symmetrical when the tilt angle is in the range of 88° to 86°. That is, the thickness of the transparent substrate 1021 is 80μm, and the first side 1021a is designed with tilting and covering the first reflective layer F1. Without special design, the tilt angle of the second side 1021b can be in the range of 86° to 88°.

[0117] In this embodiment of the application, taking a transparent substrate 1021 with a thickness of 80 μm, a tilt angle of 86° for the first side 1021a, and a distance D2 of 60 μm between the second side 1021b and the second light-emitting unit 1023 as an example, the curves of the luminous brightness of the first light-emitting unit 1022 and the second light-emitting unit 1023 as a function of the viewing angle are obtained.

[0118] Figure 18 This is a schematic diagram showing the change in luminance of a first light-emitting unit as a function of viewing angle, according to an embodiment of this application. Figure 19 This is a schematic diagram showing the change in luminance of a second light-emitting unit as a function of viewing angle, according to an embodiment of this application. (Reference) Figure 18 and Figure 19It can be seen that the luminance curve of the first light-emitting unit 1022 changes with the viewing angle has good symmetry, and the luminance curve of the second light-emitting unit 1023 changes with the viewing angle also has good symmetry. This ensures good color uniformity when the light emitted by the first light-emitting unit 1022 and the light emitted by the second light-emitting unit 1023 are mixed at different viewing angles.

[0119] It should be noted that in the various luminance variation curves described in the above embodiments, the horizontal axis represents the viewing angle, which can range from -100° to 100°, and the vertical axis represents the luminance, with units of candela per square meter (cd / m²). 2 The curves show overlap at some points of view, so a single curve is used to represent them.

[0120] In this embodiment, the refractive index of the transparent substrate 1021 and the first light-shielding layer 103 can be greater than the refractive index of air. Therefore, the light emitted by the first light-emitting unit 1022 can only exit from the surface of the transparent substrate 1021 away from the driving back plate 101 when the angle of the light emitted by the first light-emitting unit 1022 is less than the angle of total internal reflection, and the light emitted by the second light-emitting unit 1023 can only exit from the surface of the transparent substrate 1021 away from the driving back plate 101 when the angle of the light emitted by the second light-emitting unit 1023 is less than the angle of total internal reflection.

[0121] Taking a transparent substrate 1021 and the first light-shielding layer 103 with a refractive index of 1.5, air with a refractive index of 1, and the distance between the first light-emitting unit 1022 and the first side surface 1021a being 30 μm, and the thickness of the transparent substrate 1021 being 80 μm as an example, the total internal reflection angle can be equal to arcsin(1 / 1.5) >> 41.8.

[0122] If the design is not based on the scheme of this application, then refer to Figure 20 When the light emitted by the first light-emitting unit 1022 exits from near the first side 1021a, light rays with an angle greater than 20.5° are absorbed by the first light-shielding layer 103 and cannot be emitted; only light rays with an angle less than or equal to 20.5° can be emitted. When the light emitted by the first light-emitting unit 1022 exits from near the second side 1021b, light rays with an angle less than the total internal reflection angle (41.8°) can be emitted, while light rays with an angle greater than the total internal reflection angle are totally internally reflected within the transparent substrate 1021 and cannot be emitted. That is, the angle range of the first light rays near the first side 1021a is smaller than the angle range of the first light rays near the second side 1021b. This results in poor uniformity of light emission brightness at different viewing angles, and consequently, color shift problems may occur even when the light-emitting component 102 includes multiple light-emitting units.

[0123] In the embodiments of this application, reference is made to Figure 21If both the first side surface 1021a and the second side surface 1021b are tilted and covered with reflective layers, when the light emitted by the first light-emitting unit 1022 exits from near the first side surface 1021a, light rays with an angle greater than 20.5° will strike the first reflective layer F1 on the first side surface 1021a and be reflected by the first reflective layer F1 before exiting. When the light emitted by the first light-emitting unit 1022 exits from near the second side surface 1021b, light rays with an angle greater than the total internal reflection angle may also strike the second reflective layer F2 on the second side surface 1021b after total internal reflection within the transparent substrate 1021 and be reflected by the second reflective layer F2 before exiting. That is, the angular range of the first light ray near the first side 1021a can be increased. Since the distance between the second side 1021b and the first light-emitting unit 1022 is relatively large, the light ray from the first light-emitting unit 1022 to the second side 1021b will experience some attenuation due to the path, thus not significantly increasing the angular range of the first light ray near the second side 1021b, and having a smaller impact on the light mixing effect. Similarly, when the light emitted by the second light-emitting unit 1023 exits from near the second side 1021b, light rays with an angle greater than 20.5° will strike the second reflective layer F2 on the second side 1021b and be reflected by the second reflective layer F2 before exiting. When the light emitted by the second light-emitting unit 1023 exits from near the first side 1021a, light rays with an angle greater than the total internal reflection angle may also strike the first reflective layer F1 on the first side 1021a after total internal reflection within the transparent substrate 1021, and be reflected by the first reflective layer F1 before exiting. That is, the angle range of the second light rays near the second side 1021b can be increased. Since the distance between the first side 1021a and the second light-emitting unit 1023 is relatively far, the light rays from the second light-emitting unit 1023 to the first side 1021a will be attenuated due to the path. Therefore, the angle range of the second light rays near the first side 1021a will not be significantly increased, and the effect on the mixing effect of the light is small.

[0124] refer to Figure 22 If the first side surface 1021a is tilted and covered with a reflective layer, when the light emitted by the first light-emitting unit 1022 exits from near the first side surface 1021a, light rays with an angle greater than 20.5° will strike the first reflective layer F1 on the first side surface 1021a and be reflected by the first reflective layer F1 before exiting. When the light emitted by the first light-emitting unit 1022 exits from near the second side surface 1021b, light rays with an angle greater than the total internal reflection angle are totally internally reflected within the transparent substrate 1021 and absorbed by the first light-shielding layer 103. That is, the angular range of the first light rays near the first side surface 1021a can be increased. This can improve the uniformity of the luminous brightness of the first light-emitting unit 1022 under different viewing angles.

[0125] If the first side 1021a is tilted and covered with a reflective layer, and the second side 1021b satisfies the condition: H / D2 = 4 / 3. (Reference) Figure 23 When the light emitted by the first light-emitting unit 1022 exits from near the first side surface 1021a, light rays with an angle less than 20.5° are emitted directly, while light rays with an angle greater than 20.5° are reflected by the first reflective layer F1 on the first side surface 1021a before exiting. When the light emitted by the first light-emitting unit 1022 exits from the second side surface 1021b, light rays with an angle less than the total internal reflection angle (41.8°) are emitted, while light rays with an angle greater than the total internal reflection angle (41.8°) are absorbed by the first light-shielding layer 103. (Reference) Figure 24 The brightness curve of the first light-emitting unit 1022 as a function of the viewing angle is approximately symmetrical with respect to the 0-angle viewing angle. When the light emitted by the second light-emitting unit 1023 exits from near the second side 1021b, light rays with angles less than arctan4 / 3 >> 36.87° will be emitted, while light rays with angles greater than 36.87° will be absorbed by the first light-shielding layer 103. When the light emitted by the second light-emitting unit 1023 exits from the first side 1021a, light rays with angles less than the total internal reflection angle (41.8°) will be emitted, while light rays with angles greater than the total internal reflection angle (41.8°) will strike the first reflective layer F1 on the first side 1021a and be reflected by the first reflective layer F1 before exiting. (Reference) Figure 19 The luminance curve of the second light-emitting unit 1023 as a function of the viewing angle is approximately symmetrical with respect to the 0-angle viewing angle.

[0126] That is, the symmetry of the luminance curve of the first light-emitting unit 1022 with the viewing angle relative to the 0-angle view, and the symmetry of the luminance curve of the second light-emitting unit 1023 with the viewing angle relative to the 0-angle view are both relatively good. As a result, the color uniformity of the light emitted by the first light-emitting unit 1022 and the light emitted by the second light-emitting unit 1023 after mixing the light at different viewing angles is relatively good.

[0127] Figure 25 This is a top view of a light-emitting component provided in an embodiment of this application. (Reference) Figure 25 The length of the first light-emitting unit 1022 along the second direction Y is greater than the length of the second light-emitting unit 1023 along the second direction Y. The second direction Y intersects the first direction X, for example, the second direction Y is perpendicular to the first direction X. Furthermore, the light-emitting component 102 may also include a third light-emitting unit 1024 located on the side of the transparent substrate 1021 near the driving backplate 101. The emission color of the third light-emitting unit 1024 is different from the emission color of the first light-emitting unit 1022, and also different from the emission color of the second light-emitting unit 1023.

[0128] For example, the first light-emitting unit 1022 emits green light (green, G), meaning the first light-emitting unit 1022 can be called a green light-emitting unit. The second light-emitting unit 1023 emits blue light (blue, B), meaning the second light-emitting unit 1023 can be called a blue light-emitting unit. The third light-emitting unit 1024 emits red light (red, R), meaning the third light-emitting unit 1024 can be called a red light-emitting unit.

[0129] refer to Figure 25 The third light-emitting unit 1024 and the first light-emitting unit 1022 are arranged along the first direction X, and the third light-emitting unit 1024 and the second light-emitting unit 1023 are arranged along the second direction Y. That is, the first light-emitting unit 1022, the second light-emitting unit 1023 and the third light-emitting unit 1024 can form a triangular arrangement.

[0130] Optionally, the orthographic projections of the first light-emitting unit 1022, the second light-emitting unit 1023, and the third light-emitting unit 1024 onto the transparent substrate 1021 can all be rectangular. Of course, they can also be other shapes, such as circles, ellipses, and polygons, etc.

[0131] For example, the orthographic projection of the first light-emitting unit 1022 onto the transparent substrate 1021 along the first direction X can be 80 μm, and the orthographic projection of the first light-emitting unit 1022 onto the transparent substrate 1021 along the second direction Y can be 130 μm. The orthographic projection of the second light-emitting unit 1023 onto the transparent substrate 1021 along both the first direction X and the second direction Y is 80 μm. The orthographic projection of the third light-emitting unit 1024 onto the transparent substrate 1021 along both the first direction X and the second direction Y is 80 μm. The distance between the orthographic projections of the first light-emitting unit 1022 and the second light-emitting unit 1023 onto the transparent substrate 1021, and the distance between the first light-emitting unit 1022 and the third light-emitting unit 1024 onto the transparent substrate 1021, can both be 25 μm. The distance between the orthographic projections of the second light-emitting unit 1023 and the third light-emitting unit 1024 onto the transparent substrate 1021 can also be 25 μm. It should be noted that the dimensions mentioned above are for illustrative purposes only.

[0132] Optionally, the third distance D3 between the third light-emitting unit 1024 and the second side 1021b can be equal to the second distance D2 between the second light-emitting unit 1023 and the second side 1021b, and the distance between the third light-emitting unit 1024 and the first side 1021a can be equal to the distance between the third light-emitting unit 1024 and the first side 1021a. In this case, the curve of the luminance of the third light-emitting unit 1024 changing with the viewing angle can be approximately the same as the curve of the luminance of the second light-emitting unit 1023 changing with the viewing angle, that is, the curve of the luminance of the third light-emitting unit 1024 changing with the viewing angle is approximately symmetrical with respect to the 0-angle view. This results in better color uniformity of the light emitted by the first light-emitting unit 1022, the second light-emitting unit 1023, and the third light-emitting unit 1024 after mixing at different viewing angles.

[0133] In this embodiment, the light-emitting component 102 includes light-emitting pixels, and each light-emitting pixel includes a light-emitting unit. Optionally, when the light-emitting component 102 includes green light-emitting pixels (green, G), blue light-emitting pixels (blue, B), and red light-emitting pixels (red, R), the light-emitting component 102 can be an RGB three-in-one light-emitting chip. In this embodiment, the light emission color of a light-emitting unit can refer to the light emission color of the light-emitting pixel to which the light-emitting unit belongs. For example, if a green light-emitting pixel includes a first light-emitting unit 1022, meaning the light-emitting pixel to which the first light-emitting unit 1022 belongs is a green light-emitting pixel, and the light emission color of the green light-emitting pixel is green, then the light emission color of the first light-emitting unit 1022 can be considered to be green. If a blue light-emitting pixel includes a second light-emitting unit 1023, meaning the light-emitting pixel to which the second light-emitting unit 1023 belongs is a blue light-emitting pixel, and the light emission color of the blue light-emitting pixel is blue, then the light emission color of the second light-emitting unit 1023 can be considered to be blue. The red light-emitting pixel includes the third light-emitting unit 1024. That is, the light-emitting pixel to which the third light-emitting unit 1024 belongs is the red light-emitting pixel. The light-emitting color of the red light-emitting pixel is red. Therefore, the light-emitting color of the third light-emitting unit 1024 can be considered to be red.

[0134] When the light-emitting component 102 does not include the color conversion unit 1025, the first distance D1 between the first light-emitting unit 1022 and the first side surface 1021a can refer to the distance between the side of the first light-emitting unit 1022 closest to the transparent substrate 1021 and the first side surface 1021a. The second distance D2 between the second light-emitting unit 1023 and the second side surface 1021b can refer to the distance between the side of the second light-emitting unit 1023 closest to the transparent substrate 1021 and the second side surface 1021b. The third distance D3 between the third light-emitting unit 1024 and the second side surface 1021b can refer to the distance between the side of the third light-emitting unit 1024 closest to the transparent substrate 1021 and the second side surface 1021b.

[0135] Figure 26 This is a schematic diagram of the structure of another display substrate provided in the embodiments of this application. Figure 27 yes Figure 26 The diagram shows a schematic representation of the light-emitting component in the display substrate. (Reference) Figure 26 and Figure 27 The light-emitting component 102 may further include a color conversion unit 1025 located between the transparent substrate 1021 and the first light-emitting unit 1022. When the light-emitting component 102 also includes a second light-emitting unit 1023 and a third light-emitting unit 1024, the color conversion unit 1025 is located on the side of the second light-emitting unit 1023 and the third light-emitting unit 1024 closest to the transparent substrate 1021. That is, the first light-emitting unit 1022, the second light-emitting unit 1023, and the third light-emitting unit 1024 can all be located on the side of the color conversion unit 1025 furthest from the transparent substrate 1021. In this case, the light emitted from the first light-emitting unit 1022, the second light-emitting unit 1023, and the third light-emitting unit 1024 can all be directed towards the color conversion unit 1025 and then emitted after passing through the color conversion unit 1025.

[0136] For example, the first light-emitting unit 1022, the second light-emitting unit 1023, and the third light-emitting unit 1024 may include a first semiconductor layer A1 and three light-emitting functional layers A2. Each light-emitting functional layer may include a light-emitting layer and a second semiconductor layer stacked along a direction perpendicular to and away from the transparent substrate 1021.

[0137] Optionally, the first semiconductor layer A1 may include a first sub-layer and a second sub-layer stacked along a direction away from the transparent substrate 1021. The first sub-layer may be made of gallium nitride buffer layer, and the second sub-layer may be made of N-type gallium nitride (denoted as N-GaN). The light-emitting layer may be made of multiple quantum well (MQW), and the second semiconductor layer may be made of P-type gallium nitride (denoted as P-GaN).

[0138] In this configuration, the light-emitting layer in each light-emitting functional layer can be connected to the first semiconductor layer. Here, the first semiconductor layer is located on the light-emitting side of each light-emitting functional layer, and the first semiconductor layer A1 is closer to the transparent substrate 1021 than each light-emitting functional layer A2. Therefore, the first semiconductor layer A1 can contact the side of the light-emitting layer in each light-emitting functional layer A2 that is away from the second semiconductor layer.

[0139] In addition, each light-emitting unit may also include a first electrode and a second electrode. The first electrode A3 is connected to the light-emitting functional layer A2, and the second electrode (not shown in the figure) is connected to the first semiconductor layer. The second electrodes of the multiple light-emitting units included in the light-emitting component 102 can be shared. Furthermore, the first electrode A3 and the second electrode are also connected to the driving backplate 101. The driving backplate 101 provides driving signals to the first electrode A3 and the second electrode to drive the light-emitting units to emit light.

[0140] Optionally, each light-emitting unit, composed of each light-emitting functional layer and the first semiconductor layer, is used to emit a first light, which includes at least one of blue light and ultraviolet light. Under the action of the color conversion unit 1025, the light-emitting component 102 can emit at least one of red light, green light, and blue light.

[0141] refer to Figure 27 The color conversion unit 1025 includes: a second light-shielding layer 10251, a limiting dam layer 10252, an optical functional layer 10253, and a filter layer 10254.

[0142] The second light-shielding layer 10251 in the color conversion unit 1025 can be located on one side of the transparent substrate 1021. This second light-shielding layer 10251 can have a light-transmitting hole K. When the light-emitting component 102 includes multiple light-emitting units, the second light-shielding layer 10251 can have multiple light-transmitting holes K corresponding to the multiple light-emitting units. Each light-transmitting hole K can be correspondingly disposed with a corresponding light-emitting unit. Optionally, the orthographic projection of each light-transmitting hole K on the transparent substrate 1021 can overlap with the orthographic projection of the light-emitting functional layer of the corresponding light-emitting unit on the transparent substrate 1021. For example, the orthographic projection of the light-emitting functional layer in the light-emitting unit on the transparent substrate 1021 can be located within the orthographic projection of the corresponding light-transmitting hole K on the transparent substrate 1021.

[0143] The defining dam layer 10252 in the color conversion unit 1025 can be located on the side of the second light-shielding layer 10251 facing away from the transparent substrate 1021. The defining dam layer 10252 has an opening region Q corresponding to the light-transmitting hole K, and the orthographic projection of the opening region Q on the transparent substrate 1021 overlaps with the orthographic projection of the corresponding light-transmitting hole K on the transparent substrate 1021. When the light-emitting component 102 includes multiple light-emitting units, the defining dam layer 10252 can have multiple opening regions Q corresponding one-to-one with the multiple light-transmitting holes K, and these opening regions Q can also correspond one-to-one with the multiple light-emitting functional layers of the multiple light-emitting units. Here, the orthographic projection of each opening region Q in the defining dam layer 10252 on the transparent substrate 1021 can overlap with the orthographic projection of the corresponding light-transmitting hole K on the transparent substrate 1021, and can also overlap with the orthographic projection of the light-emitting functional layer of the corresponding light-emitting unit on the transparent substrate 1021. For example, the light-emitting side of the light-emitting functional layer in the light-emitting unit can all face the corresponding opening area Q, and the orthographic projection of the light-emitting functional layer of the light-emitting unit on the transparent substrate 1021 can be located within the orthographic projection of the corresponding opening area Q on the transparent substrate 1021. The orthographic projection of each opening area Q in the limiting dam layer 10252 on the transparent substrate 1021 can be located within the orthographic projection of the corresponding light-transmitting hole K on the transparent substrate 1021.

[0144] When the light-emitting component 102 includes a first light-emitting unit 1022, a second light-emitting unit 1023, and a third light-emitting unit 1024, the light-emitting functional layer of the first light-emitting unit 1022, the light-emitting functional layer of the second light-emitting unit 1023, and the light-emitting functional layer of the third light-emitting unit 1024 are all used to emit first light in the working state.

[0145] Accordingly, the multiple opening regions Q in the defined dam layer 10252 may include: a first opening region, a second opening region, and a third opening region. The first opening region may be positioned opposite to the light-emitting functional layer of the first light-emitting unit 1022, the second opening region may be positioned opposite to the light-emitting functional layer of the second light-emitting unit 1023, and the third opening region may be positioned opposite to the light-emitting functional layer of the third light-emitting unit 1024.

[0146] The optical functional layer 10253 in the color conversion unit 1025 can be located inside the opening area Q of the defining dam layer 10252. At least a portion of the optical functional layer 10253 is used to convert the color of light entering the optical functional layer 10253. Here, the light emitted from the light-emitting unit can be directed towards the optical functional layer 10253, and after the optical functional layer 10253 converts the color of the light, it is emitted after passing through the light-transmitting hole K of the second light-shielding layer 10251.

[0147] Optionally, the optical functional layer 10253 in the color conversion unit 1025 may include a first color conversion section, a second color conversion section, and a third color conversion section. The first color conversion section may be located within a first opening region, the second color conversion section may be located within a second opening region, and the third color conversion section may be located within a third opening region.

[0148] In this configuration, the first light emitted from the light-emitting functional layer of the first light-emitting unit 1022 can be directed towards the first color conversion unit, and the first light can either pass through the first color conversion unit or be converted by the first color conversion unit. The first light emitted from the light-emitting functional layer of the second light-emitting unit 1023 can be directed towards the second color conversion unit, and the second color conversion unit converts the first light emitted from the light-emitting functional layer of the second light-emitting unit 1023 into light of another color. The first light emitted from the third light-emitting functional layer of the third light-emitting unit 1024 can be directed towards the third color conversion unit, and the third color conversion unit converts the first light emitted from the light-emitting functional layer of the third light-emitting unit 1024 into light of another color.

[0149] The first color conversion unit is used to convert the first light beam into green light. For example, the first color conversion unit includes green quantum dots that convert the first light beam into green light; preferably, the first color conversion unit also includes scattering particles for scattering the light. Here, the first light beam emitted from the light-emitting functional layer of the first light-emitting unit 1022, after striking the first color conversion unit distributed within the first opening area, is converted into green light by the green quantum dots, and the first light beam and green light are scattered by the scattering particles. This ensures that more of the first light beam can be converted into green light by the green quantum dots, and that the converted green light has a large emission angle, thus ensuring a large viewing angle for the display substrate integrating the light-emitting component 102. In this case, the green light-emitting pixel may include the first light-emitting unit 1022 and the first color conversion unit.

[0150] The second color conversion section is used to convert the first light into blue light or maintain blue light emission. For example, when the first light contains only blue light, the second color conversion section can be a transparent section or can include blue quantum dots (QDs). The transparent section allows direct transmission of the first light, while the blue quantum dots can be used to convert the first light into blue light with a wavelength different from the first light. Preferably, the second color conversion section also includes scattering particles that scatter the light. Here, the first light emitted from the light-emitting functional layer of the second light-emitting unit 1023, after striking the second color conversion section distributed in the second opening area, is scattered by the scattering particles to ensure a large blue light emission angle, thereby ensuring a large viewing angle for the display substrate integrating the light-emitting component 102. For another example, when the first light contains ultraviolet light, the second color conversion section includes blue quantum dots that convert the first light into blue light, or the second color conversion section simultaneously contains scattering particles for scattering light and blue quantum dots for converting ultraviolet light into blue light. Here, the first light emitted from the light-emitting functional layer of the second light-emitting unit 1023, after striking the second color conversion section distributed in the second opening area, converts the ultraviolet light in the first light into blue light through blue quantum dots. The first light and blue light are then scattered by scattering particles, ensuring that more ultraviolet light is converted into blue light by the blue quantum dots and that the converted blue light has a large emission angle, thus ensuring a large viewing angle for the display substrate integrating the light-emitting component 102. In this case, the blue light-emitting pixel may include the second light-emitting unit 1023 and the second color conversion section.

[0151] The third color conversion unit is used to convert the first light beam into red light. For example, the third color conversion unit includes red quantum dots that convert the first light beam into red light; preferably, the third color conversion unit also includes scattering particles for scattering the light. When the first light beam emitted from the light-emitting functional layer of the third light-emitting unit 1024 is incident on the third color conversion unit distributed within the third opening region, the red quantum dots convert the first light beam into red light, and the scattering particles scatter both the first light beam and the red light, ensuring that more of the first light beam can be converted into red light by the red quantum dots, and ensuring that the converted red light has a large emission angle, thus ensuring a large viewing angle for the display substrate integrating the light-emitting component 102. In this case, the red light-emitting pixel may include the third light-emitting unit 1024 and the third color conversion unit.

[0152] A filter layer 10254 may be located between a transparent substrate 1021 and an optical functional layer 10253. The filter layer 10254 includes filter units corresponding to light-transmitting holes K. The orthographic projection of the filter unit on the transparent substrate 1021 overlaps with the orthographic projection of the corresponding light-transmitting hole K on the transparent substrate 1021. Optionally, the filter layer 10254 may include multiple filter units corresponding one-to-one with multiple light-transmitting holes K, wherein the orthographic projection of each filter unit on the transparent substrate 1021 may overlap with the orthographic projection of the corresponding light-transmitting hole K on the transparent substrate 1021.

[0153] For example, the multiple filter units in the filter layer 10254 may include a first filter unit, a second filter unit, and a third filter unit. Here, the first filter unit may be configured corresponding to the first color conversion unit, the second filter unit may be configured corresponding to the second color conversion unit, and the third filter unit may be configured corresponding to the third color conversion unit.

[0154] For example, the first light emitted by the light-emitting functional layers of the first light-emitting unit 1022, the second light-emitting unit 1023, and the third light-emitting unit 1024 is all blue light. The first filter unit can be a green color block, which can transmit green light and absorb other colors of light. In this way, the light emitted from the first color conversion unit can pass through the first filter unit before exiting, and the first filter unit can filter out light of colors other than green light, so as to ensure that the green sub-pixel G in the light-emitting component 102 can filter out the blue light component. It should be noted that in other possible implementations, the first filter unit can also be a film layer for transmitting green light and reflecting blue light. In this way, after the light emitted from the first color conversion unit hits the first filter unit, the green light in these rays can pass through the first filter unit before exiting, while the blue light in these rays can be reflected back to the first color conversion unit by the first filter unit, so that the green quantum dots in the first color conversion unit can excite this blue light into green light again, thus further improving the excitation efficiency of the green quantum dots. In this case, the green light-emitting pixel may include a first light-emitting unit 1022, a first color conversion unit, and a first filter unit.

[0155] For example, the first light emitted by the light-emitting functional layers of the first light-emitting unit 1022, the second light-emitting unit 1023, and the third light-emitting unit 1024 is all blue light. The second filter unit can be a blue color block that can transmit blue light and absorb other colors of light. In this way, the light emitted from the second color conversion unit can pass through the second filter unit before exiting, and the second filter unit can filter out light of colors other than blue light, so as to ensure that the blue sub-pixel B in the light-emitting component 102 can emit relatively pure blue light. In this case, the blue light-emitting pixel may include the second light-emitting unit 1023, the second color conversion unit, and the second filter unit.

[0156] For example, the first light emitted by the light-emitting functional layer of the first light-emitting unit 1022, the light-emitting functional layer of the second light-emitting unit 1023, and the light-emitting functional layer of the light-emitting unit are all blue light. The third filter unit can be a red color resist, which can transmit red light and absorb other colors of light. In this way, the light emitted from the third color conversion unit can pass through the third filter unit before being emitted, and the third filter unit can filter out light of colors other than red light, so as to ensure that the red sub-pixel R in the light-emitting component 102 can filter out the blue light component. It should be noted that in other possible implementations, the third filter unit can also be a film layer for transmitting red light and reflecting blue light. In this way, after the light emitted from the third color conversion unit is incident on the third filter unit, the red light in these rays can pass through the third filter unit before being emitted, while the blue light in these rays can be reflected back to the third color conversion unit by the third filter unit, so that the red quantum dots in the third color conversion unit can excite this blue light into red light, thereby further improving the excitation efficiency of the red quantum dots. In this case, the red light-emitting pixel may include a third light-emitting unit 1024, a third color conversion unit, and a third filter unit.

[0157] It should be noted that the film structure of the first filter unit and the third filter unit can be the same and can be prepared by the same process; for example, both the first filter unit and the third filter unit are films that transmit red and green light and reflect blue light.

[0158] It should be noted that since the orthographic projection of each filter unit in the filter layer 10254 onto the transparent substrate 1021 overlaps with the orthographic projection of the corresponding light-transmitting hole K in the second light-shielding layer 10251 onto the transparent substrate 1021, a portion of the second light-shielding layer 10251 is distributed between two adjacent filter units in the filter layer 10254 in the direction parallel to the extension surface of the transparent substrate 1021. In this way, light emitted from the side of a filter unit in the filter layer 10254 can be absorbed by the second light-shielding layer 10251, thereby ensuring that the light intensity emitted by each sub-pixel towards adjacent sub-pixels is low, effectively reducing the probability of color crosstalk in the light-emitting component 102.

[0159] Further reference Figure 27 The color conversion unit 1025 includes a first encapsulation layer 10255, which can be located on the side of the limiting dam layer 10252 facing away from the transparent substrate 1021. The first encapsulation layer 10255 can encapsulate the limiting dam layer 10252, the optical functional layer 10253, and the filter layer 10254 to prevent water and oxygen in the external environment from penetrating the limiting dam layer 10252 and eroding the optical functional layer 10253 or the filter layer 10254. This ensures that the optical functional layer 10253 can stably convert the color of light, resulting in high reliability of the optical functional layer 10253.

[0160] refer to Figure 27 The color conversion unit 1025 may further include a second encapsulation layer 10256 located between the first light-shielding layer 103 and the defining dam layer 10252. Both the optical functional layer 10253 and the defining dam layer 10252 in the color conversion unit 1025 may be located on the side of the second encapsulation layer 10256 facing away from the transparent substrate 1021, and the second encapsulation layer 10256 needs to cover at least the outer surface of the second light-shielding layer 10251 and the side of the second light-shielding layer 10251 facing away from the transparent substrate 1021. In this case, the second encapsulation layer 10256 can encapsulate the second light-shielding layer 10251, preventing water and oxygen from the external environment from eroding the optical functional layer 10253 through the second light-shielding layer 10251 and the defining dam layer 10252.

[0161] The first encapsulation layer 10255 can be a film layer structure that is continuously distributed at all locations. Similarly, the second encapsulation layer 10256 can also be a film layer structure that is continuously distributed at all locations. Furthermore, the orthographic projections of the defining dam layer 10252 and the optical functional layer 10253 onto the transparent substrate 1021 are both within the orthographic projection of the first encapsulation layer 10255 onto the transparent substrate 1021, and also within the orthographic projection of the second encapsulation layer 10256 onto the transparent substrate 1021. Simultaneously, the second encapsulation layer 10256 is in contact with the first encapsulation layer 10255, so that the cooperation between the first encapsulation layer 10255 and the second encapsulation layer 10256 can completely encapsulate the defining dam layer 10252 and the optical functional layer 10253. Here, the area where the second encapsulation layer 10256 contacts the first encapsulation layer 10255 is distributed around the defining dam layer 10252. Thus, through the cooperation of the first encapsulation layer 10255 and the second encapsulation layer 10256, the encapsulation effect of the optical functional layer 10253 is ensured to be good, and the reliability of the optical functional layer 10253 is further improved.

[0162] In this embodiment of the application, each light-emitting unit in the light-emitting component 102 and the color conversion unit 1025 can be bonded together by a connecting layer 1026. That is, a connecting layer 1026 for bonding the two together is distributed between each light-emitting unit and the color conversion unit 1025.

[0163] Additionally, refer to Figure 27 The light-emitting component 102 also includes a barrier structure 1027 surrounding each light-emitting unit, which protects the light-emitting unit. The light-emitting component 102 also includes a first insulating layer 1028 located on the side of each light-emitting functional layer A2 away from the transparent substrate 1021. A first electrode is connected to a second semiconductor layer of the light-emitting functional layer A2 through a via in the first insulating layer 1028, and a second electrode is connected to the first semiconductor layer through a via in the first insulating layer 1028. The light-emitting component 102 also includes a second insulating layer 1029 located on the side of the first electrode A3 and the second electrode away from the transparent substrate 1021. The second insulating layer 1029 can expose at least a portion of the first electrode A3 and each of the second electrodes for connection to the driving backplate 101.

[0164] When the light-emitting component 102 includes a color conversion unit 1025, the first distance D1 between the first light-emitting unit 1022 and the first side surface 1021a can be the distance between the side of the light-transmitting hole K corresponding to the first light-emitting unit 1022 near the transparent substrate 1021 and the first side surface 1021a in the second light-shielding layer 10251. The second distance D2 between the second light-emitting unit 1023 and the second side surface 1021b can be the distance between the side of the light-transmitting hole K corresponding to the second light-emitting unit 1023 near the transparent substrate 1021 and the second side surface 1021b in the second light-shielding layer 10251. The third distance D3 between the third light-emitting unit 1024 and the third side surface can be the distance between the side of the light-transmitting hole K corresponding to the third light-emitting unit 1024 near the transparent substrate 1021 and the second side surface 1021b in the second light-shielding layer 10251.

[0165] In summary, this application provides a display substrate including a driving backplate, multiple light-emitting components, and a first light-shielding layer. The ratio of the thickness of the transparent substrate in the light-emitting component to the distance between the first light-emitting unit and the first side surface is less than or equal to 2, thereby reducing the brightness attenuation of the first light rays near the first side surface. And / or, the first side surface is designed at an angle and covered with a first reflective layer to increase the light intensity of the first side surface, thereby making the light intensity of the first light rays near the first side surface and the light intensity of the first light rays near the second side surface similar. This improves the problem of poor brightness uniformity of the light-emitting components at different viewing angles, enhancing the display effect of the display substrate.
