Detailed Description
As used herein, the terms "first," "second," …, etc., do not denote any order or sequence, nor are they used to limit the present invention, but rather are used to distinguish one element from another or from another element or operation described in the same technical language.
As used herein, the terms "comprising," "including," "having," "containing," and the like are open-ended terms that mean including, but not limited to. The following detailed description of the embodiments of the detection circuit according to the present invention is provided in conjunction with the accompanying drawings, which are not intended to limit the scope of the invention.
It will be understood that when an element such as a layer, film, region, or substrate is referred to as being "on" or "connected to" another element, it can be directly on or connected to the other element or intervening elements may also be present. In contrast, when an element is referred to as being "directly on" or "directly connected to" another element, there are no intervening elements present.
Fig. 2A is a schematic diagram of the light emitting module 10. The tiled light source device 1 includes a plurality of light emitting modules 10.
As shown in fig. 2A, the tiled light source apparatus 1 is divided into a plurality of sub-areas within a predetermined setting range S, and each sub-area is provided with one light emitting module 10. The light emitting modules 10 are arranged in an array, and the adjacent light emitting modules 10 are connected to each other.
For example, the light emitting modules 10 arranged along the first direction D1 are juxtaposed and abut against each other with the side edges perpendicular to the first direction D1; the light emitting modules 10 arranged along the second direction D2 abut against each other with the side edges perpendicular to the second direction D2, thereby forming the tiled light source device 1.
Fig. 2B is a schematic diagram of an embodiment of the light emitting module 10. Each light emitting module 10 includes a substrate 110, a light emitting unit 120, and a driving unit.
As shown in fig. 2B, the substrate 110 has a first surface 111, and the light emitting unit 120 is located on the first surface 111. The substrate 110 is, for example, a glass substrate. The light emitting unit 120 is, for example, a light emitting diode or a micro light emitting diode.
Fig. 2C is an enlarged sectional view of the light emitting module 10. As shown in fig. 2C, the substrate 110 has a first surface 111 and a second surface 112. The first surface 111 and the second surface 112 are located on opposite sides of the substrate 110. The driving unit 130 is located on the second surface 112 and electrically connected to the light emitting unit 120.
For example, as shown in fig. 2B and 2C, the substrate 110 has a plurality of through holes 114, and the through holes 114 penetrate through the first surface 111 and the second surface 112. The driving unit 130 may be electrically connected to the light emitting unit 120 through the through hole 114.
With this design, as shown in fig. 2B, the distance between the outermost light emitting unit 120 on the substrate 110 and the edge of the substrate 110 can be reduced, that is, the space of the light emitting module 10 originally reserved for the driving unit on the first surface 111 can be eliminated, thereby avoiding the problem of edge banding after the different light emitting modules 10 are spliced.
From another perspective, the space available for the light emitting units 120 on the first surface 111 of the substrate 110 is increased, so that the light emitting units 120 can be more uniformly distributed on the substrate 110. Further, such a design may provide a more uniform distribution of display brightness.
Fig. 3A, 3B and 3C are rear views of different embodiments of the light emitting module 10.
As shown in fig. 3A, the driving unit 130 is directly disposed on the second surface 112. For example, a Chip-On-Glass (COG) method is used to be disposed On the second side 112.
In addition, in this embodiment, each light emitting module 10 further includes a flexible circuit 140. The flexible circuit 140 is disposed on the second surface 112 and electrically connected to the driving unit 130. The flexible circuit 140 is, for example, a Flexible Printed Circuit (FPC) or a Flexible Flat Cable (FFC).
Further, the flexible circuit 140 is used for transmitting signals from a carrier module (not shown), and has one end fixed to the second surface 112 in a thermocompression manner and the other end connected to the carrier module.
As shown in fig. 3B, the second side 112 may be additionally provided with a driving unit 130 as required. As described above, the space available for the light emitting units 120 on the first surface 111 of the substrate 110 increases, which can increase the number of the light emitting units 120.
Or, for example, the first surface 111 uses the light emitting units 120 with smaller size, and the second surface 112 may be provided with additional driving units 130A according to the increase of the number of the light emitting units 120. In other words, this design is more flexible in operation of the driving unit 130 as well as the light emitting unit 120.
As shown in fig. 3C, the flexible circuit 140 is disposed on the second surface 112. The driving unit 130 is disposed on the flexible circuit 140 and electrically connected to the flexible circuit 140.
For example, the driving unit 130 is disposed On the second surface 112 in a Chip-On-Film (COF) manner. Therefore, when one end of the flexible circuit 140 is fixed on the second surface 112 by hot pressing, the flexible circuit 140 and the driving unit 130 are simultaneously disposed, and the manufacturing process can be simplified.
In addition, similar to the example shown in fig. 3B, the number of the driving units 130 on the flexible circuit 140 may also be increased according to the requirement.
Fig. 4 is a rear view of an embodiment of the tiled light source device 1. For convenience of illustration of the relationship between the light emitting module 10 and the carrier module 20, the through holes are not shown in fig. 4 and the similar figures.
As shown in fig. 4, the tiled light source apparatus 1 includes a carrier module 20 and a plurality of light emitting modules 10. Carrier board module 20 is disposed on second side 112 and covers a portion of second side 112. The carrier module 20 is electrically connected to each light emitting module 10,
in this embodiment, the carrier board module 20 includes a circuit carrier board 21 and a control carrier board 23. The circuit carrier 21 is disposed on the second surface 112 and electrically connected to the light emitting module 10.
As shown in fig. 4, the circuit carrier 21 has nine connecting portions 142, eight of which are electrically connected to the driving units 130 of different light emitting modules 10 via the flexible circuits 140, and another connecting portion 142A is used for electrically connecting to the control carrier 23. It is understood that the number and form of the connecting portions (142, 142A) are not limited thereto. The control carrier 23 may contain, for example, components and lines for supplying power, and may be transferred to different light emitting modules 10 via the circuit carrier 21.
Since each light emitting module 10 has the driving unit 130, when it is found that the driving unit 130 of a light emitting module 10 is damaged, the light emitting module 10 is only required to be detached from the connecting portion 142 of the circuit carrier 21 and replaced with a new light emitting module, so that the operation of the split type light source device is easier to maintain.
It should be noted that, in the example of fig. 4, the driving unit 130 and the flexible circuit 140 are as shown in fig. 3A, and in other embodiments, the driving unit and the flexible circuit may also be as shown in fig. 3C. In addition, the tiled light source device 1 can further include a protective glass (not shown) on one side of the first surface of the substrate 110 for fixing the relative position of each light emitting module 10, so that the edges of the light emitting modules 10 are aligned.
Fig. 5A-1 is a rear view of another embodiment of the tiled light source apparatus 1A. The difference from the tiled light source apparatus 1A of fig. 4 is that a fastening component is disposed on the carrier module 20.
As shown in fig. 5A-1, a second engaging member 220 is disposed on a surface (opposite to the second surface 112) of the circuit carrier 21 opposite to the light emitting module 10. The second engaging member 220 is, for example, a bayonet mechanism, and is used for electrically connecting with the control carrier. On the other hand, please refer to the enlarged sectional view of the light emitting module 10 in fig. 5A-2.
As shown in fig. 5A-2, the carrier module 20 further includes a first engaging member 210 disposed on a surface of the circuit carrier 21 facing the substrate 110. The first engaging member 210 may have a plurality of positions corresponding to the light emitting modules 10. The light emitting module 10 further includes a first engaging portion 150 corresponding to the first engaging member 210.
Therefore, each light emitting module 10 can be combined with the first engaging member 210 on the circuit carrier 21 by the first engaging portion 150, so as to fix the relative position of each light emitting module 10, and align the edges between the light emitting modules 10.
In other embodiments, the positions of the first engaging member 210 and the first engaging portion 150 may be interchanged, that is, the first engaging member 210 is disposed on the second surface 112, and the first engaging portion 150 is disposed on a surface of the circuit carrier 21 facing the substrate 110.
In the example of fig. 5A-1, the driving unit 130 and the flexible circuit 140 are as shown in fig. 3A, but in other embodiments, the driving unit and the flexible circuit can also be as shown in fig. 3C.
In another embodiment, the first engaging member 210 and the first engaging portion 150 can serve as an interface for electrical connection, that is, the driving unit 130 and the circuit carrier 21 of the carrier module 20 can be electrically connected by the combination of the first engaging portion 150 and the first engaging member 210, and at this time, the flexible circuit can be omitted.
Fig. 5B is a rear view of another embodiment of the tiled light source device 1A. As shown in fig. 5B, the control carrier 23 is disposed on a surface of the circuit carrier 21 opposite to the light emitting module 10, and the control carrier 23 is inserted into the second engaging member 220 shown in fig. 5A-1 to complete the assembly of the tiled light source apparatus 1A. Since each light emitting module 10 has the driving unit 130, when the driving unit 130 of a light emitting module 10 is found to be damaged, the light emitting module 10 is only required to be detached from the connecting portion 142 and the engaging member of the circuit carrier 21 and replaced with a new light emitting module, so that the operation of the splicing type light source device 1A is easier to maintain.
Fig. 6A-1 is a rear view of another embodiment of the light module 10. As shown in fig. 6A-1, the light emitting modules 10 are distributed in an array, and the second surface 112 of the substrate 110 is provided with a driving unit 130.
Fig. 6A-2 is a schematic diagram of another embodiment of the carrier board module 20. As shown in fig. 6A-2, in this embodiment, the carrier module 20 is a control integrated carrier having a plurality of openings 230 corresponding to each of the driving units 130 on the light emitting module 10.
Fig. 6A-3 are rear views of another embodiment of the tiled light source arrangement 1B. As shown in fig. 6A-3, the carrier module 20 is disposed on the second surface 112 of the light emitting module 10 to complete the assembly of the tiled light source apparatus 1B. Carrier module 20 covers a portion of second side 112. For example, the position of the light emitting module 10 corresponding to the driving unit 130 is not covered, and the driving unit 130 can be exposed to the carrier module 20 through the opening 230. The carrier board module 20 is thereby electrically connected with each of the light emitting modules 10, and the relative position of each of the light emitting modules 10 is fixed such that the edges between the light emitting modules 10 are aligned.
Fig. 6B is an enlarged sectional view of the light emitting module 10. In the example of fig. 6B, the light emitting module 10 for fig. 6A-1 and 6A-3 is presented.
The difference from the previous embodiment is that, as shown in fig. 6B, in this embodiment, the light emitting module 10 is provided with a conductive adhesive on one side of the second surface 112 for electrically connecting with the carrier module 20. Specifically, each light emitting module 10 has a bump 160 on the second surface 112 for transmitting a signal to the driving circuit 130, and a conductive adhesive 170 (e.g., an anisotropic conductive adhesive) is disposed between the bump 160 and the carrier module 20, so that the light emitting module 10 can be fixed on the carrier module 20 by a pressing method and electrically connected to the carrier module 20.
With this design, when it is found that the driving unit 130 of one light emitting module 10 is damaged, only the conductive adhesive 170 on the light emitting module 10 needs to be removed to detach the light emitting module 10 from the carrier board module 20 and replace the light emitting module 10 with a new one, so that the operation of the split-type light source device 1B is easier to maintain.
The present invention has been described in relation to the above embodiments, which are only exemplary of the implementation of the present invention. It must be noted that the disclosed embodiments do not limit the scope of the invention. On the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the invention as defined by the appended claims.
