To facilitate an understanding of the present application, the present application will now be described more fully with reference to the accompanying drawings. Preferred embodiments of the present application are given in the accompanying drawings. This application may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the description of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.
Referring to fig. 1 to 12, the display module according to the embodiment of the present disclosure includes a light conversion layer 40, and a first display panel 10 and a second display panel 10a that are spliced together.
The first display panel 10 includes a first display region 101 and a first tiled display region 102 adjacent to the first display region 101, and the second display panel 10a includes a second display region 101a and a second tiled display region 102a adjacent to the second display region 101 a.
Specifically, referring to fig. 2, fig. 3, fig. 6 and fig. 7, the first display panel 10 is disposed adjacent to the second display panel 10a, the first tiled display area 102 is disposed adjacent to the second tiled display area 102a, and a seam area 800 is disposed between the first tiled display area 102 and the second tiled display area 102 a; at least a portion of the light conversion layer 40 is disposed on one side of the patchwork area 800.
Specifically, when the display module is spliced, the display module may include two, three, four, etc. display panels, for convenience of description, the first display panel 10 and the second display panel 10a are spliced as an example, and it should be understood by those skilled in the art that the splicing manner of any two adjacent display panels and the splicing manner of the first display panel 10 and the second display panel 10a may be the same.
The first display panel 10 and the second display panel 10a in the display module are adjacent to each other, and a gap formed by splicing is formed between the first display panel 10 and the second display panel, and the gap is the splicing region 800. The first tiled display area 102 of the first display panel 10 is adjacent to the second tiled display area 102a of the second display panel 10a, the other area of the first display panel 10 except the first tiled display area 102 is the first display area 101, and the other area of the second display panel 10a except the second tiled display area 102a is the second display area 101 a.
At least part of the light conversion layer 40 is disposed at one side of the seam region 800, that is, the light conversion layer 40 covers at least the seam region 800, and in this embodiment, the light conversion layer 40 covers the first tiled display area 102, the seam region 800 and the second tiled display area 102 a.
It can be seen that, the display module provided in the embodiment of the present application is provided with the light conversion layer 40 in the seam area 800 of the first display panel 10 and the second display panel 10a, and when the light conversion layer 40 covers the seam area, the light conversion layer also covers the first tiled display area 102 of the first display panel 10 and the second tiled display area 102a of the second display panel 10 a. The light conversion layer 40 can not only cover the gap, but also perform light conversion on the light emitted from the first tiled display area 102 and the light emitted from the second tiled display area 102a, so that the light conversion layer 40 can also perform image display, thereby making the gap at the tiled part invisible, increasing the continuity of the display screen, and improving the display effect. That is, the display module assembly that this application embodiment provided covers the gap of concatenation department through light conversion layer 40, and utilizes the light conversion characteristic of light conversion layer 40 to make concatenation seam area 800 department also can carry out image display, makes the gap of concatenation department invisible completely, improves the continuity of display image.
It will be understood by those skilled in the art that the first display area 101 and the first tiled display area 102 are both provided with first light emitting diodes and the second display area 101a and the second tiled display area 102a are both provided with second light emitting diodes. The first and second light emitting diodes include blue, red, and green light emitting diodes.
Specifically, the light conversion layer 40 has a characteristic of converting blue light into red light or green light, and therefore, the first light emitting diode of the first tiled display area 102 and the second light emitting diode of the second tiled display area 102a are both set as the blue light emitting diode 30, and the light exit surface (i.e., the surface away from the gap at the tiled location) of the light conversion layer 40 can emit the red light or the green light, so that the gap at the tiled location is changed into a part of a pixel, i.e., the pixel at the gap can also display an image. That is, since the gap is covered with the light conversion layer 40 and the image can be displayed by using the light conversion property of the light conversion layer 40, the gap at the joint is not visible at all and the image is not broken when the image is displayed.
In detail, referring to fig. 1 and 5, the first display panel 10 includes a first driving backplane 20 and first light emitting diodes, and the first light emitting diodes include a blue light emitting diode 30, a red light emitting diode 31 and a green light emitting diode 32. On the surface of the first driving backplane 20, the first light emitting diodes on the first display area 101 are arranged in the order of the blue light emitting diodes 30, the red light emitting diodes 31, and the green light emitting diodes 32. The second display panel 10a includes a second driving back plate 20a and second light emitting diodes including blue light emitting diodes 30, red light emitting diodes 31, and green light emitting diodes 32. On the surface of the second driving back plate 20a, the second light emitting diodes on the second display area 101a are arranged in the order of the blue light emitting diode 30, the red light emitting diode 31, and the green light emitting diode 32.
The first led of the first tiled display area 102 is a blue led 30, and the second led of the second tiled display area 102a is also a blue led 30. Then, referring to fig. 2 and 6, the light conversion layer 40 is covered on the gap where the first display panel 10 and the second display panel 10a are spliced, and the light conversion layer 40 further extends to the blue light emitting diode 30 covered on the first tiled display area 102 and the second tiled display area 102 a. Therefore, the light conversion layer 40 can cover the gap at the joint, and the light conversion property of the light conversion layer 40 is used to convert the light of the blue light emitting diode 30 into red light or green light, so that the joint forms a complete pixel after the first display panel and the second display panel are jointed.
When the display modules are spliced, the display modules spliced under different requirements may have gaps in different directions. Taking the example that the display module includes four display panels, if the four display panels are spliced in a row and a column, the spliced display module has 3 longitudinal slits 80, that is, the splicing region 800 has a longitudinal slit at this time. If the four display panels are spliced in a row and four lines, the spliced display module has 3 transverse slits 80a, that is, the splicing region 800 has the transverse slits 80 a. If the four display panels are spliced in two rows and two columns, the spliced display module has 1 longitudinal gap 80 and 1 transverse gap 80a, that is, at this time, part of the spliced seam area 800 has the longitudinal gap 80, and the rest of the spliced seam area 800 has the transverse gap 80 a.
The arrangement of the light conversion layer 40 is different for the slits in two different directions, namely the transverse slit 80a and the longitudinal slit 80, and the two arrangements are described in detail below. Before explaining the arrangement of the light conversion layers 40 in both the lateral slits 80a and the longitudinal slits 80, the arrangement of the light emitting diodes on each display panel is explained.
In an alternative embodiment, the first display panel 10 and the second display panel 10a are spliced in two rows and two columns with a longitudinal slit 80 formed therebetween. The following details:
referring to fig. 1, the first display panel 10 includes a plurality of leds arranged in a matrix, and is now described by taking two rows and five columns of leds arranged locally as an example, where each row of the two rows of leds is distributed as follows: blue light emitting diode 30, red light emitting diode 31, green light emitting diode 32, blue light emitting diode 30; the distribution mode of each row of the five rows of light-emitting diodes is as follows: a first column of two blue light emitting diodes 30, a second column of two red light emitting diodes 31, a third column of two green light emitting diodes 32, a fourth column of two blue light emitting diodes 30, a fifth column of two blue light emitting diodes 30.
The second display panel 10a includes a plurality of leds arranged in a matrix, and is now described by taking two rows and four columns of leds arranged locally as an example, where the two rows of leds are distributed in the following manner: blue light emitting diodes 30, red light emitting diodes 31, green light emitting diodes 32; the four columns of leds are distributed in the following manner: a first column of two blue light emitting diodes 30, a second column of two blue light emitting diodes 30, a third column of two red light emitting diodes 31, a fourth column of two green light emitting diodes 32. That is, the first display panel 10 and the second display panel 10a include the same number of rows of light emitting diodes with respect to the longitudinal slit 80.
Based on the arrangement of the light emitting diodes, please refer to fig. 1, if the first display panel 10 and the second display panel 10a are spliced in a row and two columns, when the first display panel 10 and the second display panel 10a are spliced, the spliced gap is a longitudinal gap 80, the left side of the longitudinal gap 80 is two blue light emitting diodes 30 in the fifth column of the first display panel 10, and the right side is two blue light emitting diodes 30 in the first column of the second display panel 10 a. Then, as can be understood by those skilled in the art, referring to fig. 2, a longitudinal slit 80 is formed at the seam region 800 of the first display panel 10 and the second display panel 10a, a middle portion of the light conversion layer 40 covers the longitudinal slit 80, a left side covers the fifth column of two blue light emitting diodes 30 of the first display panel 10, and a right side covers the first column of two blue light emitting diodes 30 of the second display panel 10 a.
For the longitudinal slit 80, the light conversion layer 40 includes a first quantum dot film and a second quantum dot film; one side of the first quantum dot film and one side of the second quantum dot film are connected. The first quantum dot film covers the light-emitting side of the first tiled display area 102, the joint of the first quantum dot film and the second quantum dot film covers the patchwork area 800, and the second quantum dot film covers the light-emitting side of the second tiled display area 102 a. The first quantum dot film may be a red quantum dot film 41, and the second quantum dot film may be a green quantum dot film 42.
Specifically, please refer to fig. 2 and fig. 3, wherein the joint of the red quantum dot film 41 and the green quantum dot film 42 covers the longitudinal slit 80, the red quantum dot film 41 covers the two blue light emitting diodes 30 in the fifth row of the first display panel 10, and the green quantum dot film 42 covers the two blue light emitting diodes 30 in the first row of the second display panel 10 a. The red quantum dot film 41 converts light of the two blue light emitting diodes 30 of the fifth column of the first display panel 10 into red light, and the green quantum dot film 42 converts light of the two blue light emitting diodes 30 of the first column of the second display panel 10a into green light.
Then, at this time, for the first display panel 10, the two blue light emitting diodes 30, the red quantum dot film 41 and the green quantum dot film 42 of the fourth column of the first display panel 10 form one complete pixel; for the second display panel 10a, the red quantum dot film 41, the green quantum dot film 42, and the two blue light emitting diodes 30 of the second column of the second display panel 10a form a complete pixel.
As can be seen from the above, in this embodiment, the light conversion layer 40 covers the longitudinal gap 80, the blue light emitting diode of the first tiled display area 102, and the blue light emitting diode of the second tiled display area 102a, so as to cover the longitudinal gap 80 and display an image at the longitudinal gap 80, so that the longitudinal gap 80 at the tiled position of two adjacent display panels is invisible, which is beneficial to improving the continuity of display images and improving the display effect.
In yet another alternative embodiment, referring to fig. 5 to 7, the first display panel 10 and the second display panel 10a are spliced in a row and a column, and a transverse gap 80a is formed therebetween, which is described in detail below:
referring to fig. 5, the first display panel 10 includes three rows and six columns of leds, and the first row and the second row of leds are distributed as follows: blue light emitting diode 30, red light emitting diode 31, green light emitting diode 32, and all six light emitting diodes in the third row are provided as blue light emitting diode 30.

The second display panel 10a also comprises three rows and six columns of leds, the six leds of the first row all being arranged as blue leds 30, and the two following rows of leds each being distributed as follows: blue light emitting diode 30, red light emitting diode 31, green light emitting diode 32, blue light emitting diode 30, red light emitting diode 31, green light emitting diode 32. The distribution mode of each row of the six rows of the light-emitting diodes is as follows: a first column of three blue light emitting diodes 30, a second column of one blue light emitting diode 30 and two red light emitting diodes 31, a third column of one blue light emitting diode 30 and two green light emitting diodes 32, a fourth column of three blue light emitting diodes 30, a fifth column of one blue light emitting diode 30 and two red light emitting diodes 31, a sixth column of one blue light emitting diode 30 and two green light emitting diodes 32. That is, the first display panel 10 and the second display panel 10a have the same number of columns of light emitting diodes with respect to the transverse slit 80 a. For convenience of description, the number of rows of the light emitting diodes included in the first display panel 10 and the second display panel 10a are also set to be the same.
Based on the above led arrangement, if the first display panel 10 and the second display panel 10a are spliced in a row and a column, the spliced gap is a horizontal gap 80a, the upper side of the horizontal gap 80a is the six blue leds 30 in the third row of the first display panel 10, and the lower side is the six blue leds 30 in the first row of the second display panel 10 a. Then, as can be understood by those skilled in the art, referring to fig. 6 and 7, after the first display panel 10 and the second display panel 10a are spliced to form the transverse slit 80a, the middle of the light conversion layer 40 covering the slit covers the transverse slit 80a, the upper side covers the six blue light emitting diodes 30 in the third row of the first display panel 10, and the lower side covers the six blue light emitting diodes 30 in the first row of the second display panel 10 a.
For the lateral slit 80a, the light conversion layer includes a first quantum dot film and a second quantum dot film; one side of the first quantum dot film and one side of the second quantum dot film are connected. The first quantum dot film and the second quantum dot film both cover the light-emitting side of the first tiled display area 102, the seam area 800, and the light-emitting side of the second tiled display area 102 a. The first quantum dot film may be a red quantum dot film 41, and the second quantum dot film may be a green quantum dot film 42.
Specifically, with continued reference to fig. 6 and 7, when the stitching slit is a transverse slit 80a, the light conversion layer 40 includes two red quantum dot films 41 and two green quantum dot films 42. Wherein, a strip of red quantum dot film 41 is covered on the blue light emitting diodes 30 of the third row and the second column of the first display panel 10a, and covered on the blue light emitting diodes 30 of the first row and the second column of the second display panel 10 a; a green quantum dot film 42 overlies the blue light emitting diodes 30 of the third row and third column of the first display panel 10 and overlies the blue light emitting diodes 30 of the first row and third column of the second display panel 10 a. Another red quantum dot film 41 is covered on the blue light emitting diodes 30 of the third row and the fifth column of the first display panel 10a, and covered on the blue light emitting diodes 30 of the first row and the fifth column of the second display panel 10 a; another green quantum dot film 42 is overlaid on the blue light emitting diodes 30 of the third row and the sixth column of the first display panel 10a and overlaid on the blue light emitting diodes 30 of the first row and the sixth column of the second display panel 10 a.
Since the red quantum dot film 41 can convert the light of the blue light emitting diode 30 covered therewith into red, and the green quantum dot film 42 can convert the light of the blue light emitting diode 30 covered therewith into green, the red quantum dot film 41, the green quantum dot film 42, and the blue light emitting diode form a complete pixel. Thus, at the transverse slit 80a, there are also full pixels available for displaying the image.
As can be seen from the above, in this embodiment, the light conversion layer 40 covers the transverse slit 80a and the light emitting diodes of the two adjacent display panels, which are respectively adjacent to the transverse slit 80a, so as to cover the transverse slit 80a and display images at the transverse slit 80a, so that the transverse slit 80a at the joint of the two adjacent display panels is invisible, which is beneficial to improving the continuity of the display image and improving the display effect.
Continuing with the first display panel 10 and the second display panel 10a in fig. 5 as an example, since the blue leds 30 in the third row, the first column and the third row, the fourth column of the first display panel 10 need to provide blue light, and the blue leds 30 in the first row, the first column and the first row, the fourth column of the second display panel 10a need to provide blue light, the blue leds 30 at these positions do not need to be optically converted, and therefore, the red quantum dot film 41 and the green quantum dot film 42 only need to cover the blue leds that need to be optically converted.
For the above reasons, in the case where the patchwork area 800 presents the transverse slit 80a, the light conversion layer 40 further includes the color resist 43, and the color resist 43 is connected to the first quantum dot film on the side away from the second quantum dot film. The color resist 43 covers the light-emitting side of the first tiled display area 102, the seam area 800, and the light-emitting side of the second tiled display area 102 a. At this time, the light conversion layer rendering resistors 43, the red quantum dot films 41, the green quantum dot films 42, the color resistors 43, the red quantum dot films 41 and the green quantum dot films 42 are arranged, wherein one color resistor 43 covers the blue light emitting diodes 30 of the third row and the first column of the first display panel 10 and covers the blue light emitting diodes 30 of the first row and the first column of the second display panel 10 a; another color resist 43 covers the third row and fourth column of blue leds 30 of the first display panel 10 and covers the first row and fourth column of blue leds 30 of the second display panel 10 a. Specifically, the color resist 43 may be a blue color resist or a transparent color resist.
That is, in the case where the stitching slit is the transverse slit 80a, none of the blue light emitting diodes 30 in the third row, the first column and the third column of the first display panel 10 and the blue light emitting diodes 30 in the first row, the first column and the first row, the fourth column of the second display panel 10a are covered by the red quantum dot film 41 or the green quantum dot film 42. In order to cover the gap at the position and improve the display effect, the color resistor 43 can be covered on the blue light emitting diode 30 which is positioned at the two sides of the transverse gap 80a but does not need to perform light conversion, the color resistor 43 can cover the rest gap, and the generation of mixed light at the splicing position can be avoided.
Fig. 10 shows a case where the first display panel 10 and the second display panel 10a both include three rows and twelve columns of light emitting diodes, where the blue light emitting diodes 30 of the third row of the first display panel 10 and the blue light emitting diodes 30 of the first row of the second display panel 10a are covered by the light conversion layer 40, and the light conversion layer 40 includes four sets of the color resistors 43, the red quantum dot films 41, and the green quantum dot films 42 which are repeatedly arranged.
In an alternative embodiment, the first tiled display area 102 and the second tiled display area 102a include at least one pixel area. That is, for the longitudinal slit, referring to fig. 2, the first tiled display area 102 may include only the fifth row of blue leds 30, and the second tiled display area 102a includes only the first row of blue leds, where the first tiled display area 102 and the second tiled display area 102a are tiled to form a complete pixel area.
Or as shown in fig. 9, the first tiled display area 102 includes four light emitting diodes in the second to fifth rows, and of course, the four light emitting diodes are all set as blue light emitting diodes 30; the second tiled display area 102a includes a first column of blue light emitting diodes. At this time, the first tiled display area 102 and the second tiled display area 102a are tiled into two complete pixel areas. Of course, the second tiled display area 102a can also be configured to include multiple columns of blue LEDs. The number of pixel areas formed by splicing the first spliced display area 102 and the second spliced display area 102a is increased, so that the splicing difficulty is reduced, and the display effect is improved.
It should be understood that the above expressions of the number of rows and the number of columns of the light emitting diodes in each display panel are merely exemplary illustrations of the arrangement of the light emitting diodes in a part of each display panel, and are not limited by the number.
Of course, when the first display panel 10 and the second display panel 10a are spliced to form the transverse slit 80a, the light conversion layer 40 may be extended to cover ten pixel regions, so as to increase the convenience of splicing.
It will be appreciated by those skilled in the art that the fourth column of blue leds of the first display panel needs to emit blue light at this time, and does not need to convert the layer to red or green light, and then the color resist 43 may be disposed to cover the fourth column of blue leds 30 of the first display panel 10 at this time. At this time, the light conversion layer 40 is formed by arranging a red quantum dot film 41, a green quantum dot film 42, a color resist 43, a red quantum dot film 41, and a green quantum dot film 42. That is, for the longitudinal slit 80, if there are more pixels displayed in the first tiled display area 102 and the second tiled display area 102a, the color-resisting member 43 may be disposed, and the color-resisting member 43 may be a blue color-resisting or a transparent color-resisting. The color resistor 43 can prevent the generation of mixed light, and can make the light-emitting surface of the light conversion layer 40 flat, thereby increasing the display effect.
In an alternative embodiment, referring to fig. 3, fig. 4, fig. 7 and fig. 8, the first tiled display area 102 is provided with a first groove, and the second tiled display area 102a is provided with a second groove; the first light emitting diode of the first tiled display area 102 is arranged in the first groove, and the second light emitting diode of the second tiled display area 102a is arranged in the second groove; the light conversion layer 40 covers the first light emitting diode, the patchwork area 800 and the second light emitting diode. Therefore, the light emitting surfaces of the four areas, namely the first display area 101, the first spliced display area 102, the second display area 101a and the second spliced display area 102a, are flush, and the display effect is improved. Of course, the first and second leds are blue leds 30.
That is, referring to fig. 3, the right side of the surface of the first driving backplate 20 of the first display panel 10 is provided with a first groove, the left side of the surface of the second driving backplate 20a of the first display panel 10 is provided with a second groove, the rightmost blue led 30 of the first display panel 10 is located in the first groove, and the leftmost blue led 30 of the second display panel 10a is located in the second groove. At this time, the positions of the rightmost blue led 30 of the first display panel 10 and the leftmost blue led 30 of the second display panel 10a slightly sink, so that the light-emitting surface of the light conversion layer 40, the light-emitting surface of the first display area 101, and the light-emitting surface of the second display area 101a are arranged to be flush with each other, and thus the light-emitting surface of the entire display module is relatively flat, thereby improving the light-emitting stability and preventing bright lines or hidden lines from appearing during image display. Of course, when the first tiled display area 102 and the second tiled display area 102a display a plurality of pixel regions, all the leds covered by the light conversion layer are set to be sunk as shown in fig. 9.
In an alternative embodiment, referring to fig. 4, 8 and 9, the display module further includes a supporting pillar 50, the supporting pillar 50 is disposed in the seam region 800, and a vertical projection of the light conversion layer 40 in the seam region 800 at least partially covers the supporting pillar 50.
Specifically, the supporting posts 50 may be disposed in the gap formed by splicing the two display panels, and the supporting posts 50 may be disposed in the gap formed by splicing the two display panels, so as to support the light conversion layer 40. That is, by providing the supporting pillars 50, the supporting pillars 50 are filled in the gaps under the light conversion layer 40, and the light conversion layer 40 can be supported, so that the light conversion layer 40 is more stable.
In an alternative embodiment, both ends of the light conversion layer 40 extend out of the seam region 800, and the display module further includes a support frame 60. One end of the supporting frame 60 is connected to the display screen box, and the other end of the supporting frame 60 supports the end of the light conversion layer 40 extending to the outside of the splicing region 800.
Specifically, before the first display panel 10 and the second display panel 10a are spliced, the light conversion layer 40 is placed on the display cabinet, in order to enhance the stability of the light conversion layer 40, the support frame 60 is fixed on the display cabinet, and then the light conversion layer 40 is fixed on the support frame 60. Of course, it is understood by those skilled in the art that two ends of the light conversion layer 40 are respectively supported by a support frame. Fig. 11 shows a schematic structural diagram of the support frame 60 supporting the light conversion layer 40 in fig. 2.
Referring to fig. 12, taking an example that the display module includes 16 display panels, and the 16 display panels are spliced in four rows and four columns, the 16 display panels form three longitudinal slits 80 and three transverse slits 80 a. Correspondingly, three longitudinally extending light conversion layers 40 are required to be provided to cover the three longitudinal slits 80, and three laterally extending light conversion layers 40 are required to be provided to cover the three lateral slits 80 a. To ensure the stability of the light conversion layers 40, a support bracket 60 is disposed at each of the two ends of each light conversion layer 40 to support the two ends of each light conversion layer 40.
