Therefore, the present application is intended to cover modifications and changes of the present application that fall within the scope of the corresponding claims (technical solutions for protection) and their equivalents. It should be noted that the implementation methods provided in the embodiments of the present application can be combined with each other without contradiction.

[0036] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0037] As described in the background technology section, how to improve the luminous efficiency of the Micro-LED display, reduce the reflectivity of the display surface of the Micro-LED display, and improve the display quality of the display has become a research hotspot in this field.

[0038] In view of this, an embodiment of the present application provides a display panel, such as Figure 1 As shown, the display panel includes:

[0039] A first substrate 10 and a second substrate 20 are arranged opposite to each other, wherein the first substrate 10 is an array substrate;

[0040] A plurality of LEDs 30 located on a side of the array substrate facing the second substrate 20;

[0041] A light shielding layer located on the side of the second substrate 20 facing the first substrate 10, the light shielding layer includes a plurality of light shielding units 40, in a first direction X, the light shielding units 40 have a first surface and a second surface opposite to each other, the first surface contacts the second substrate 20, the second surface contacts the first substrate 10, and the area of ​​the first surface is larger than the area of ​​the second surface, and the light shielding units 40 are at least partially located in the gap between adjacent LEDs 30; wherein the first direction X is perpendicular to the first substrate 10;

[0042] The reflecting unit 50 is at least located on a portion of the surface of the shading unit 40. Optionally, the reflecting unit 50 is a metal layer, but the present application does not limit this, and it depends on the specific situation.

[0043] Optionally, in one embodiment of the present application, the light-shielding layer may be an ink layer, but the present application does not limit this and it depends on the specific circumstances.

[0044] It should be noted that, in the embodiment of the present application, since the first substrate 10 is an array substrate, the side of the second substrate 20 away from the first substrate 10 is the light emitting surface of the display panel, that is, the display surface of the display panel.

[0045] Optionally, in one embodiment of the present application, Figure 2 As shown, a plurality of pixel circuits 11 are disposed in the array substrate, and the pixel circuits 11 are used to control the light emitting state of the LED 30, thereby controlling the display of the display panel.

[0046] In the display panel provided in the embodiment of the present application, the shading layer includes a plurality of shading units 40, wherein the shading units 40 are at least partially located in the gaps between adjacent LEDs 30, and at least partially provided with reflecting units 50 on the surfaces of the shading units 40, so that the reflecting units 50 can be utilized to reflect the light emitted from the side of the LED 30, and at least partially reflect the light emitted from the side of the LED 30 toward the display surface of the display panel, thereby improving the light utilization rate of the LED 30, and further improving the light emission rate of the display panel under the premise of the same driving voltage, so as to improve the luminous efficiency of the display panel.

[0047] It should be noted that the reflecting unit 50 not only reflects the light emitted from the side of the LED 30, but also reflects other light incident on its surface. In the display panel provided in the embodiment of the present application, in the first direction X, the shading unit 40 has a first surface and a second surface relative to each other, and the first surface is in contact with the second substrate 20, so that the contact surface between the shading unit 40 and the second substrate 20 can be used to absorb part of the ambient light irradiated to the display surface of the display panel, thereby preventing the reflecting unit 50 from reflecting the ambient light incident on the display panel, reducing the amount of light reflected on the display surface of the display panel, and improving the display quality of the display panel.

[0048] It should be noted that the array substrate is provided with a variety of metal traces, and the ambient light is incident on the metal traces and reflected by the metal traces to the display surface of the display panel, which will also affect the display quality of the display panel. In the display panel provided in the embodiment of the present application, the first surface of the shading unit 40 is in contact with the second substrate 20, and the contact surface between the shading unit 40 and the second substrate 20 can also be used to absorb part of the light reflected by the metal traces in the array substrate and irradiated on the second substrate 20, thereby further reducing the light emission on the display surface of the display panel and improving the display quality of the display panel.

[0049] It can be seen that the display panel provided in the embodiment of the present application can improve the luminous efficiency of the display panel, and can reduce the amount of reflection of ambient light on the display surface of the display panel, thereby improving the display quality of the display panel.

[0050] It should be noted that, in the embodiments of the present application, Figure 1 As shown, the first surface of the shading unit 40 contacts the second substrate 20, and the second surface of the shading unit 40 contacts the first substrate 10. The shading unit 40 can also be used to support the space between the first substrate 10 and the second substrate 20, thereby reducing the probability of the second substrate 20 collapsing during the use of the display panel.

[0051] Optionally, based on the above embodiment, in one embodiment of the present application, continue as follows Figure 1 As shown, in the first direction X, the first surface of the shading unit 40 overlaps with the LED 30, so that the shading unit 40 can be used to block the gaps between adjacent LEDs 30 in the first direction X, thereby maximally absorbing the ambient light that finds the display surface of the display panel and the amount of light reflected by the metal wiring in the array substrate to the second substrate 20, reducing the reflected light on the display surface of the display panel and improving the display quality of the display panel.

[0052] In another embodiment of the present application, Figure 3 As shown, in the first direction X, the first surface of the shading unit 40 does not overlap with the LED 30, so that the setting of the shading unit 40 does not affect the light emitting area of ​​the LED 30, thereby improving the utilization rate of the light emitted by the LED 30.

[0053] Optionally, in one embodiment of the present application, Figure 4 As shown, in the first direction X, the first surface of the shading unit 40 is close to the side boundary A of the LED 30 located around it and is flush with the side boundary B of the LED 30 close to the shading unit 40, so as to absorb the ambient light irradiating the display surface of the display panel and the light reflected by the metal wiring in the array substrate to the second substrate 20 to the maximum extent without affecting the light emission area of ​​the LED 30, thereby reducing the reflected light on the display surface of the display panel and improving the display quality of the display panel. However, this application is not limited to this, and it depends on the specific situation.

[0054] Based on any of the above embodiments, in one embodiment of the present application, continue as follows Figure 4As shown, in the first direction X, the shading unit 40 includes a first component 41 and a second component 42, and the first component 41 is located on the side of the second component 42 facing the second substrate 20. In this embodiment, in the second direction Y, the size of the second component 42 is smaller than the size of the first component 41, and the second direction Y is parallel to the plane where the first substrate 10 is located, so that the second component 42 can be at least partially located in the gap between adjacent LEDs 30, and the first component 41 has a larger contact area with the second substrate 20, absorbs more reflected light, and improves the display quality of the display panel.

[0055] Based on any of the above embodiments, in one embodiment of the present application, continue as follows Figure 1-Figure 4 As shown, in the first direction X, the cross-sectional view of the second component 42 is rectangular, so as to reduce the amount of light reflected by the reflection unit 50 located on the side of the second component 42 and emitted to the first substrate 10 side.

[0056] In another embodiment of the present application, Figure 5 As shown, in the first direction X, the cross-sectional view of the second component 42 is a trapezoid, and the area of ​​the second component 42 facing the first component 41 is larger than the area of ​​the second component 42 facing the first substrate 10, so as to reduce the process difficulty of the second component 42. In other embodiments of the present application, such as Figure 6 As shown, in the first direction X, when the cross-sectional view of the second component 42 is a trapezoid, the area of ​​the second component 42 facing the first component 41 may also be smaller than the area of ​​the second component 42 facing the first substrate 10, so as to increase the amount of light reflected by the reflection unit 50 located on the side of the second component and emitted to the side of the second substrate 20, thereby further improving the light emission rate of the LED 30.

[0057] In another embodiment of the present application, Figure 7As shown, the overall surface composed of the side surface of the second component 42 and the second surface (i.e., the surface of the shading unit 40 facing the first substrate 10) is an arc-shaped surface, and on the arc-shaped surface, along the direction away from the first component 41, the angle between the tangent of each point on the arc-shaped surface and the second substrate 20 gradually decreases, so that the angle between the surface of the second component 42 away from the first component 41 (i.e., the second surface) and the second substrate 20 is small or even a plane, thereby facilitating the contact between the second surface and the first substrate 10, thereby improving the stability of the shading unit 40 between the first substrate 10 and the second substrate 20.

[0058] It should be noted that, compared to the second component 42 having a flat surface or an inclined surface, the second component 41 and the second surface form an overall surface that is an arc-shaped surface, and the second component 42 can provide more reflection angles, so that the reflection unit 50 located on the side of the second component 42 can reflect more light, thereby improving the luminous efficiency of the display panel. Compared to the second component 42 and the second surface having an overall surface that is an arc-shaped surface, the second component 41 has a flat surface or an inclined surface, and the process of the light shielding unit 40 is relatively simple.

[0059] Specifically, in one embodiment of the present application, when the surface of the second component 42 is a plane or an inclined surface, the shading unit 40 can be formed by a double-layer film forming and developing process, that is, formed by two developing and etching processes, or can be formed by a half-tone mask by one developing and etching process. The present application does not limit this, and it depends on the specific situation. Optionally, in this embodiment, the manufacturing process of the display panel includes: manufacturing the shading layer (that is, the shading unit 40) on the second substrate 20; fixing the LED 30 on the first substrate 10; and bonding the second substrate 20 and the first substrate 10.

[0060] Optionally, in one embodiment of the present application, Figure 5 and Figure 7 As shown, the angle between the tangent line of the contact position between the second component 42 and the first component 41 and the second substrate 20 is in the range of 10° to 85°, so that the reflected light on the side of the second component 42 has a good reflection effect on the light emitted from the side of the LED 30, and the process difficulty is relatively low. It should be noted that in this embodiment, if the side of the second component is an inclined surface, such as Figure 5As shown, the angle between the tangent of the contact position between the second component 42 and the first component 41 and the second substrate 20 is the angle α1 between the side surface of the second component 42 and the contact surface between the second component 42 and the first component 41; if the overall surface formed by the second component 42 and the second surface is an arc surface, the angle between the tangent of the contact position between the second component 42 and the first component 41 and the second substrate 20 is the angle α2 between the tangent of the contact point between the side surface of the second component 42 and the first component 41 and the surface of the second component 42 facing the first component.

[0061] Based on any of the above embodiments, in one embodiment of the present application, Figure 8 As shown, the reflection unit 50 is located on the side of the second component 42. Optionally, the reflection unit 50 covers the side of the second component 42, so as to reflect all the light emitted from the LED 30 to the side of the second component 42, thereby improving the luminous efficiency of the display panel.

[0062] It should be noted that in the above embodiments, Figure 8 As shown, the reflecting unit 50 may be located only on the side of the second component 42. Figure 1 As shown, it can also extend to cover a portion of the surface area of ​​the first component 41 facing the first substrate 10, and the present application does not limit this, and it depends on the specific situation.

[0063] Optionally, in one embodiment of the present application, continue as Figure 7 As shown, if the overall surface formed by the second component 42 and the second surface is an arc-shaped surface, the reflection unit 50 can also extend to cover at least a portion of the surface of the first component 41 facing the first substrate 10, so as to reduce the process complexity of the reflection unit 50. Figure 7 As shown, the reflection unit 50 extends to cover a partial area of ​​the first component 41 facing the surface of the first substrate 10, and also extends to cover the entire area of ​​the first component 41 facing the surface of the first substrate 10. The present application does not limit this, and it depends on the specific circumstances.

[0064] Based on any of the above embodiments, in one embodiment of the present application, Figure 8 and Fig. 9As shown, in the first direction X, the height h1 of the second component 42 is not less than the height h2 of the LED 30, so that when the reflection unit 50 is only located on the side of the second component 42, all the light emitted from the side of the LED 30 can be reflected, so as to increase the light emission of the display panel under the same driving voltage, thereby improving the luminous efficiency of the display panel.

[0065] Optionally, in one embodiment of the present application, continue as Fig. 9 As shown, in the first direction X, the height h1 of the second component 42 is greater than the height h2 of the LED 30, so that in the first direction X, the first component 41 is located on the side of the LED 30 facing the second substrate 20, so that even if the size of the first component 41 in the second direction Y is larger, it will not affect the arrangement of the LED 30. It should be noted that the embodiment of the present application does not limit the size of the second component 42 in the second direction Y, as long as it can meet the requirements of the supporting performance of the first substrate 10 and the second substrate 20.

[0066] Based on any of the above embodiments, in one embodiment of the present application, Fig. 9 and Fig.10 As shown, the plurality of LEDs 30 include LEDs 31 of a first color, LEDs 32 of a second color, and LEDs 33 of a third color, and the LEDs 31 of the first color, LEDs 32 of the second color, and LEDs 33 of the third color are periodically arranged on the first substrate 10, so that the display panel can achieve full-color display. Optionally, in this embodiment, the LEDs 31 of the first color are red LEDs, the LEDs 32 of the second color are green LEDs, and the LEDs 33 of the third color are blue LEDs, but this application does not limit this, and it depends on the specific situation.

[0067] In another embodiment of the present application, Fig.11 As shown, the multiple LEDs 30 are LEDs of the same color, that is, all LEDs 30 in the display panel are LEDs of the same color. Optionally, the multiple LEDs 30 may all be LEDs of a first color, or may all be LEDs of a second color, or may all be LEDs of a third color or a fourth color. The present application does not impose any limitation on this, and it depends on the specific circumstances.

[0068] The display panel provided in the embodiment of the present application is described below by taking the case where the multiple LEDs are all LEDs of a third color, such as blue LEDs, as an example.

[0071] Based on the above embodiments, in one embodiment of the present application, Fig.13 As shown, the display panel further includes: a fourth light modulating unit 71 located in the first display area and located on a surface of the reflecting unit 50 on a side away from the shading unit 40, wherein the fourth light modulating unit 71 emits light of the first color based on the light emitted by the LED 33 of the third color, so as to modulate the light emitted from the side of the LED 33 of the third color into the light of the first color and then reflect it;

[0072] The fifth light modulation unit 72 is located in the second display area and on the surface of the side of the reflection unit 50 away from the shading unit 40. The fifth light modulation unit 72 emits light of the second color based on the light emitted by the LED 33 of the third color, so as to modulate the light emitted from the side of the LED 33 of the third color into light of the second color and then reflect it.

[0074] It should be noted that when the fourth light modulation unit 71 or the fifth light modulation unit 72 is not provided on the surface of the reflecting unit 50 away from the shading unit 40, for the first display area, the light emitted from the side of the LED 33 of the third color is directly emitted to the reflecting unit 50, and the reflecting unit 50 reflects the light of the third color, and the reflected light of the third color is converted into the light of the first color when passing through the first light modulation unit 61 and emitted from the display panel. Similarly, for the second display area, the light emitted from the side of the LED 33 of the third color is directly emitted to the reflecting unit 50, and the reflecting unit 50 reflects the light of the third color, and the reflected light of the third color is converted into the light of the second color when passing through the second light modulation unit 62 and emitted from the display panel.

[0075] When the fourth light modulation unit 71 or the fifth light modulation unit 72 is set on the surface of the reflecting unit 50 away from the shading unit 40, for the first display area, the third color light emitted from the side of the LED 33 of the third color is first emitted to the fourth light modulation unit 71, converted into the first color light and then reflected by the light of the reflecting unit 50.
