[0031] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the specific technical solutions of the present application will be further described in detail below in combination with the drawings in the embodiments of the present application. The following embodiments are used to illustrate the present application, but not to limit the scope of the present application.

Therefore, the features defined with "first" and "second" can explicitly or implicitly include one or more of the features. In the description of the embodiments of the present application, unless otherwise specified, the meaning of "a plurality of" is two or more.

[0033] In addition, in the embodiments of the present application, the orientation terms such as "up", "down", "left" and "right" are defined with respect to the orientation of the components shown in the drawings, and it should be understood that these directional terms are relative concepts, which are used for relative description and clarification, and can be changed accordingly according to the change of the orientation of the components placed in the drawings.

[0034] In the embodiments of the present application, unless specifically defined and limited otherwise, the term "connection" should be interpreted broadly, for example, "connection" can be fixed connection, or detachable connection, or integral; can be directly connected, or indirectly connected through intermediate medium.

[0035] In the embodiments of the present application, the terms "comprising", "containing" or any other variant thereof are intended to cover non-exclusive inclusion, so that the process, method, article or apparatus including a series of elements not only includes those elements, but also includes other elements not explicitly listed, or further includes elements inherent to such process, method, article or apparatus. Without more limitation, the element defined by the sentence "including a…" does not exclude the presence of other identical elements in the process, method, article or apparatus including the element.

[0036] In the embodiments of the present application, the words "exemplary" or "for example" are used to mean serving as an example, instance, or illustration. Any embodiment or design described herein as "exemplary" or "for example" should not be construed as being preferred or advantageous over other embodiments or designs. Rather, the exemplary or for example embodiments are intended to convey concepts in a concrete manner.

[0037] The following references are cited below Figures 1-5 A display screen 10 is described according to the embodiments of the present application.

[0038] As shown in Figures 1-5 The present application provides a display screen 10, comprising: a plurality of spliced substrates 1, light-emitting LEDs 2, excitation LEDs 3 and the spliced substrates 1.

[0039] Specifically, as shown in Figures 1-5 The spliced substrates 1 are connected to each other, and each two adjacent spliced substrates 1 have a splicing seam 13; the light-emitting LEDs 2 are arranged on one side of the spliced substrates 1 in the thickness direction; the excitation LEDs 3 are arranged on the same side of the spliced substrates 1 in the thickness direction as the light-emitting LEDs 2, and the excitation LEDs 3 are arranged on both sides of each splicing seam 13; and the dot film assembly 4 is arranged opposite to the excitation LEDs 3 and the splicing seam 13 in the thickness direction of the spliced substrates 1.

[0040] It should be noted that the light-emitting LEDs 2 are disposed on the splicing substrate 1 and fixed to the splicing substrate 1 through a film-forming process, thereby enabling the light-emitting LEDs 2 to emit light. The light-emitting LEDs 2 can be red, green, or blue LEDs. Each splicing substrate 1 has multiple light-emitting LEDs 2, and multiple light-emitting LEDs 2 (red LEDs, green LEDs, and blue LEDs) are mixed in different proportions to produce almost all other colors. This mixing method is called additive color mixing. In additive color mixing, red, green, and blue light are mixed together, and the human eye can perceive a new color.

[0041] Specifically, red LEDs are made of semiconductor materials doped with gallium phosphide and emit red light; green LEDs are made of semiconductor materials doped with indium phosphide and emit green light; and blue LEDs are doped with materials such as gallium nitride or aluminum gallium nitride and emit blue light.

[0042] A red LED, a green LED, and a blue LED are arranged in a fixed order to form a pixel. Different colors can be mixed within each pixel by adjusting the brightness (i.e., the current) of the three LEDs. For example, when the brightness of the red LED and the green LED in a pixel is the same, the corresponding color displayed on the screen is yellow; when the brightness of the red LED increases while the brightness of the green LED decreases, various colors from red to orange can be mixed. In this way, a wide range of colors can be generated.

[0043] It is understandable that the dot film assembly 4 and the splicing seam 13 are arranged opposite to each other in the thickness direction of the splicing substrate 1, which can serve to block the splicing seam 13. Furthermore, since the excitation LED 3 and the dot film assembly 4 are arranged opposite to each other in the thickness direction of the splicing substrate 1, the excitation LED 3 can excite the quantum dot material in the dot film assembly 4, thereby enabling the quantum dot material in the dot film assembly 4 to emit light. This allows the display screen 10 to display normally at the position of the splicing seam 13, improving the display continuity of the display screen 10 and thus improving the display effect.

[0044] Furthermore, such as Figures 1-5 As shown, the display screen 10 also includes a support column 14, which is inserted into the splicing seam 13 along the thickness direction of the splicing substrate 1. One end of the support column 14 is adapted to abut against the dot film assembly 4, thereby improving the installation stability of the dot film assembly 4.

[0045] The display screen 10 provided by the embodiment of the present application has the following advantages. The excitation LED 3 is arranged on the same side of the splicing substrate 1 in the thickness direction of the splicing substrate 1 as the light-emitting LED 2. The excitation LED 3 is arranged on both sides of each splicing seam 13. The dot film assembly 4 is arranged opposite to the excitation LED 3 and the splicing seam 13 in the thickness direction of the splicing substrate 1, so that the dot film assembly 4 can shield the splicing seam 13, and the excitation LED 3 can excite the quantum dot material in the dot film assembly 4, so that the quantum dot material in the dot film assembly 4 emits light, and the display screen 10 can normally display at the position of the splicing seam 13, thereby improving the display effect.

[0046] In a possible implementation of the present application, as shown in Figures 1-5 The splicing substrate 1 includes a body part 11 and a connecting part 12. The light-emitting LED 2 is arranged on the body part 11. The connecting part 12 is adapted to be connected with the connecting part 12 of the adjacent splicing substrate 1. The connecting part 12 of the two adjacent splicing substrates 1 facing each other has a splicing seam 13. In the thickness direction of the splicing substrate 1, the end surface of the connecting part 12 facing the light-emitting LED 2 is lower than the end surface of the body part 11 facing the light-emitting LED 2. The excitation LED 3 is arranged on the side of the connecting part 12 facing the light-emitting LED 2. The dot film assembly 4 is arranged on the side of the excitation LED 3 away from the connecting part 12. In the thickness direction of the splicing substrate 1, the dot film assembly 4 is flush with the light-emitting LED 2.

[0047] It can be understood that, since the end surface of the connecting part 12 facing the light-emitting LED 2 is lower than the end surface of the body part 11 facing the light-emitting LED 2, the position of the excitation LED 3 can be lower than the position of the light-emitting LED 2, so that the dot film assembly 4 can be arranged opposite to the excitation LED 3 in the thickness direction of the splicing substrate 1 while being flush with the light-emitting LED 2, thereby further improving the display effect of the display screen 10.

[0048] In a possible implementation of the present application, as shown in Figures 1-3 A plurality of splicing substrates 1 are connected in a first direction (for example, the a direction as shown in Figure 1 A plurality of groups of splicing substrates 1 are arranged in a second direction. The dot film assembly 4 is arranged in the first direction. Each dot film assembly 4 extends in the second direction (for example, the b direction as shown in Figure 2 The thickness direction of the splicing substrate 1, the first direction and the second direction are perpendicular to each other in pairs.

[0049] It can be understood that a plurality of spliced substrates 1 are connected to form a group of spliced substrates 1 in the first direction, a plurality of spliced seams 13 are arranged in the first direction, and the plurality of dot film assemblies 4 are arranged in the first direction, and the plurality of dot film assemblies 4 are arranged one by one with the plurality of spliced seams 13, so that the plurality of spliced seams 13 in the first direction can be blocked by the dot film assembly 4, thereby further improving the display continuity of the display screen 10, thereby improving the display effect.

[0050] Further, as shown in Figure 1 , each group of spliced substrates 1 has a support 5 at both ends in the first direction, and the support 5 is arranged to stably mount the spliced substrate 1.

[0051] In a possible implementation of the present application, as shown in Figure 1 and Figure 2 , the dot film assembly 4 includes two quantum dot films 41, and the two quantum dot films 41 are arranged in the first direction. The quantum dot film 41 is a green dot film or a red dot film, and the excitation LED 3 is a blue LED. It should be noted that the blue LED has high energy and short wavelength, and the excitation LED 3 is a blue LED, so that the quantum dot material in the quantum dot film 41 can be better excited, thereby improving the display effect.

[0052] When the quantum dot film 41 is two, the excitation LED 3 corresponding to one dot film assembly 4 is two arranged in the first direction, and the two excitation LEDs 3 are arranged one by one with the two quantum dot films 41, so that the excitation LED 3 can better excite the corresponding quantum dot film 41.

[0053] Or, as shown in Figure 1 and Figure 3 , the dot film assembly 4 includes at least three quantum dot films 41 and at least one color resistance 42 arranged in the first direction. There is one color resistance 42 every two quantum dot films 41, and the color resistance 42 is a blue color resistance 42. For example, as shown in Figure 3 , the color resistance 42 is one, and the quantum dot film 41 is four.

[0054] It can be understood that the blue color resistance 42 can only allow blue light to pass through. When the number of quantum dot films 41 in the dot film assembly 4 is greater than two, without the blue color resistance 42, since the quantum dot film 41 is a green dot film or a red dot film, the three adjacent quantum dot films 41 cannot form a pixel point (one pixel point requires red, blue and green colors). By having one color resistance 42 every two quantum dot films 41, the dot film assembly 4 can form a complete pixel point, thereby further improving the display effect of the display screen 10.

[0055] In a possible implementation of the present application, as shown in Figures 1-3As shown in the group of spliced substrates 1, the light-emitting LEDs 2 on each spliced substrate 1 are arranged in the first direction. In the first direction, the colors of any two adjacent quantum dot films 41 are different, the colors of any three adjacent light-emitting LEDs 2 are different, the colors of any two adjacent light-emitting LEDs 2 and one quantum dot film 41 or color resistance 42 are different, the colors of any adjacent one light-emitting LED 2 and two quantum dot films 41 are different, and the colors of any adjacent one light-emitting LED 2, one quantum dot film 41 and one color resistance 42 are different.

[0056] It can be understood that one light-emitting LED 2 is one sub-pixel unit, one quantum dot film 41 is one sub-pixel unit, and one color resistance 42 is one sub-pixel unit. Through the arrangement of the colors of any two adjacent quantum dot films 41, the colors of any three adjacent light-emitting LEDs 2, the colors of any two adjacent light-emitting LEDs 2 and one quantum dot film 41 or color resistance 42, the colors of any adjacent one light-emitting LED 2 and two quantum dot films 41, and the colors of any adjacent one light-emitting LED 2, one quantum dot film 41 and one color resistance 42 in the first direction, the colors of any three adjacent sub-pixel units are different, the colors of the sub-pixel units are red, blue or green, and the three adjacent sub-pixel units with different colors can form a complete pixel point, so that the display screen 10 can be displayed completely, and the display effect is improved.

[0057] In a possible implementation of the present application, as shown in Figure 4 and Figure 5 A plurality of spliced substrates 1 are connected in the second direction to form a group of spliced substrates 1, a plurality of groups of spliced substrates 1 are arranged in the first direction, the dot film assemblies 4 are spaced apart in the second direction, the dot film assemblies 4 are arranged in the first direction, and the thickness direction of the spliced substrate 1, the first direction and the second direction are perpendicular to each other.

[0058] It can be understood that a plurality of spliced substrates 1 are connected in the second direction to form a group of spliced substrates 1, and a plurality of spliced seams 13 are arranged in the second direction. Through the dot film assemblies 4 being spaced apart in the second direction, the plurality of dot film assemblies 4 are arranged one by one with the plurality of spliced seams 13, so that the plurality of spliced seams 13 in the second direction can be shielded by the dot film assemblies 4, thereby further improving the display continuity of the display screen 10, and improving the display effect.

[0059] Further, as shown in Figure 1 Each group of spliced substrates 1 has a support 5 at both ends in the second direction. The support 5 is arranged to stabilize the installation of the spliced substrate 1.

[0060] In a possible implementation of the present application, as shown in Figure 4 andFigure 5 As shown, each splicing substrate 1 is provided with multiple light-emitting LEDs 2 arranged along a first direction, and the multiple light-emitting LEDs 2 and multiple dot film assemblies 4 arranged opposite each other along a second direction are of the same color. This allows the dot film assembly 4 to adapt to the colors of different columns of light-emitting LEDs 2, thereby further improving the display effect of the display screen 10.

[0061] In one possible implementation of this application, such as Figure 4 and Figure 5 As shown, among the multiple dot film components 4 arranged along the first direction, some dot film components 4 include a quantum dot film 41, and some dot film components 4 include a color resist 42. The color resist 42 is a blue color resist 42, and the quantum dot film 41 is a green or red dot film. The excitation LED 3 is a blue LED. It should be noted that blue LEDs have high energy and short wavelength. Using a blue LED as the excitation LED 3 facilitates better excitation of the quantum dot material in the quantum dot film 41, thereby improving the display effect.

[0062] Understandably, along the second direction, when a column of LEDs 2 is a blue LED, the dot film assembly 4 on this column includes a color resist 42, which is blue and only allows blue light to pass through; when a column of LEDs 2 is a red LED, the dot film assembly 4 on this column includes a quantum dot film 41, which is a red dot film; when a column of LEDs 2 is a green LED, the dot film assembly 4 on this column includes a quantum dot film 41, which is a green dot film.

[0063] Therefore, by setting it in the above manner, the dot film assembly 4 can adapt to the colors of different columns of light-emitting LEDs 2, thereby further improving the display effect of the display screen 10.

[0064] In one possible implementation of this application, such as Figures 1-5 As shown, the width of the dot film assembly 4 along the connection direction of the splicing substrate 1 is equal to the sum of the widths of the corresponding plurality of excitation LEDs 3 along the connection direction of the splicing substrate 1 and the width of the splicing seam 13 along the connection direction of the splicing substrate 1. This allows the dot film assembly 4 to completely cover the corresponding plurality of excitation LEDs 3, thereby reducing light leakage. Simultaneously, it allows the dot film assembly 4 to completely cover the corresponding splicing seam 13, thereby improving display continuity.

[0065] In summary, the width of the film assembly along the connection direction of the splicing substrate 1 is equal to the sum of the width of the corresponding multiple excitation LEDs 3 along the connection direction of the splicing substrate 1 and the width of the splicing seam 13 along the connection direction of the splicing substrate 1, which can further improve the display effect of the display screen 10.

[0066] For example, Figures 1-3As shown, when the connecting direction of the spliced substrate 1 is the first direction, the width of the point film assembly 4 along the first direction is equal to the sum of the width of the corresponding plurality of excitation LEDs 3 along the first direction and the width of one splicing seam 13 along the first direction.

[0067] For example, as shown in Figure 4 and Figure 5 As shown, when the connecting direction of the spliced substrate 1 is the second direction, the width of the point film assembly 4 along the second direction is equal to the sum of the width of the corresponding plurality of excitation LEDs 3 along the second direction and the width of one splicing seam 13 along the first direction.

The above is only the preferred embodiment of the present application, and does not limit the patent scope of the present application. Any equivalent structure or equivalent flow conversion, or direct or indirect application in other related technical fields, is also included in the patent protection scope of the present application.
