Detailed Description
Various embodiments will be described hereinafter, and the spirit and principles of the invention should be readily understood by those skilled in the art by referring to the description taken in conjunction with the accompanying drawings. However, while certain specific embodiments are specifically illustrated herein, these embodiments are merely exemplary and are not to be considered in all respects as limiting or exhaustive. Accordingly, various changes and modifications to the invention will be apparent to those skilled in the art without departing from the spirit and principles of the invention.
First, a signal transmission device 10 according to an embodiment of the present invention will be described with reference to fig. 1. Fig. 1 shows a signal transmission device 10 according to an embodiment of the invention. The signal transmission device 10 includes a substrate layer 15, a first connection area 100 disposed on the substrate layer 15, a second connection area 200 disposed on the substrate layer 15, and a third connection area 300. The second connection area 200 of the signal transmission device 10 has a first contact block 210 electrically connected to the first connection area 100, and a second contact block 220 disposed adjacent to the first contact block 210 and electrically connected to the third connection area 300.
Specifically, referring to fig. 1, the first connection region 100 and the third connection region 300 are respectively located at two opposite sides of the second connection region 200. That is, the second connection region 200 is located between the first connection region 100 and the third connection region 300. In addition, the second connection region 200 includes a first contact block 210 and a second contact block 220 disposed adjacent to each other in parallel, which will be described in further detail below.
In the signal transmission device 10, the substrate layer 15 is provided with a plurality of contacts 25. As mentioned above, the plurality of contacts 25 are distributed in the first connection region 100, the second connection region 200, and the third connection region 300, respectively. That is, the respective connection regions may include one or more contacts 25, and the contacts 25 located in the separate connection regions may be electrically connected to each other using signal wires, respectively. Here, the contact 25 may be formed of a material such as gold, silver, copper, platinum, iridium, palladium, ruthenium, cadmium, nickel, indium, tin, or an alloy thereof. However, the present invention is not limited to the material that can be used for the contacts 25, as long as they can be used for the contacts.
Here, the signal conductors for connecting different contacts 25 may include a plurality of first signal conductors 111 arranged side by side and a plurality of second signal conductors 121 arranged side by side. The first signal wires 111 are grouped into a first signal wire group 110, and the second signal wires 121 are grouped into a second signal wire group 120. However, this is merely an example, and the plurality of first signal wires 111 or the plurality of second signal wires 121 may not be arranged side by side.
In the first signal conductive line group 110, each of the first signal conductive lines 111 has a first terminal 11 included in the first connection region 100 and a second terminal 12 included in the first contact block 210. In contrast, in the second signal conductive line group 120, each of the second signal conductive lines 121 has a third terminal 13 included in the second contact block 220 and a fourth terminal 14 included in the third connection region 300.
In this embodiment, the plurality of second end points 12 and the plurality of third end points 13 are disposed side by side, and a direction in which the first signal conducting wire 111 extends from the second end point 12 toward the first end point 11 may be different from a direction in which the second signal conducting wire 121 extends from the third end point 13 toward the fourth end point 14. For example, the direction of the first signal conducting line 111 extending from the second end point 12 to the first end point 11 may be opposite to the direction of the second signal conducting line 121 extending from the third end point 13 to the fourth end point 14. However, the directions of the signal wires corresponding to each other are only examples, and the direction of the first signal wire 111 extending from the second end 12 to the first end 11 and the direction of the second signal wire 121 extending from the third end 13 to the fourth end 14 may be varied in a variety of ways consistent with the spirit of the present invention. In the preferred embodiment, the second terminal 12 and the third terminal 13 are arranged along a direction transverse to the extension direction of the first signal conducting wire 111 or the second signal conducting wire 121. In addition, in this embodiment, the plurality of second endpoints 12 and the plurality of third endpoints 13 are arranged in a collinear side-by-side manner, and the cluster formed by the second endpoints 12 and the cluster formed by the third endpoints 13 are respectively located at two ends in the collinear direction. However, in different embodiments, the second end points 12 and the third end points 13 may be arranged side by side in a non-collinear manner, for example, the second end points 12 and the third end points may be respectively formed as straight lines spaced apart from each other and parallel to each other. In addition, the second terminal 12 and the third terminal 13 may be distributed in a staggered manner.
In the signal transmission device 10 of the present embodiment, the plurality of first terminals 11 of the first signal wire group 110 form a first connection area 100, the second terminal 12 of the first signal wire group 110 and the third terminal 13 of the second signal wire group 120 form a second connection area together, and the fourth terminal 14 of the second signal wire group 120 forms a third connection area. In particular, the respective plurality of terminals and the connected contacts 25 together define respective connection regions.
In practical applications, for example, the second connection region 200 may include 120 contacts 25 arranged side by side in a row, and the first contact 25 to the 80 th contact 25 are connected to the first connection region 100 by the first signal wire 111, and the 81 st contact 25 to the 120 th contact 25 are connected to the third connection region 300 by the second signal wire 121. However, the present invention is not limited thereto, and various numbers of contacts may be used. For convenience and brevity, the drawings and the contents thereof in the present invention will be described with a few contacts included. For example, referring to fig. 1, the second connection region 200 may include eight contacts 25 arranged side by side in a row, and the first to fourth contacts 25 to 25 are connected to the first connection region 100 by the first signal wire 111, and the fifth to eighth contacts 25 to 25 are connected to the third connection region 300 by the second signal wire 121. In the second connection area 200, the area including the contact 25 connected to the first connection area 100 is the first contact block 210, and the area including the contact 25 connected to the third connection area 300 is the second contact block 220. In view of the above, the first contact block 210 and the second contact block 220 connected to different regions are arranged in parallel without interfering with the wire connection therebetween.
In further detail, when the signal transmission device 10 shown in fig. 1 is used to transmit signals, the signal transmission direction of the first contact block 210 electrically connected with the first connection region 100 is away from the first contact block 210, and the signal transmission direction of the second contact block 220 electrically connected with the third connection region 300 is into the second contact block 220. However, the above is only an example, and it is also possible that the signal transmission direction of the first contact block 210 electrically connected with the first connection region 100 is into the first contact block 210, and the signal transmission direction of the second contact block 220 electrically connected with the third connection region 300 is out from the second contact block 220.
Under the above configuration, the signal transmission device 10 can integrate the configuration that originally needs to transmit signals respectively through different signal transmission devices and different connection interfaces, so that two or more signal transmission devices 10 and two or more connection interfaces respectively transmitting signals to different directions can be integrated, thereby improving the functions of the signal transmission device and the process and cost required by being installed on the electronic device.
In the signal transmission device 10, the substrate layer 15 may be a polyimide film (polyimide film), a polyester resin film (polyester resin film), a Polyethylene terephthalate film (Polyethylene terephthalate film), or the like. However, the above is merely an example, and the substrate layer 15 may be various material layers that can be used as a base layer, such as a material layer of a flexible printed circuit board, and the present invention is not limited to the material specifically shown herein.
Next, an aspect of a signal transmission apparatus according to various embodiments of the present invention will be described with reference to fig. 2A to 2B in combination with fig. 1.
In the signal transmission device 10 shown in fig. 1, the outline of the substrate layer 15 is designed to approximately match the area where the contacts 25 and the first and second signal lines 111 and 121 are distributed. With this design, the signal transmission device 10 can occupy less space and save materials for preparing the substrate layer 15.
However, in the signal transmission devices 20 and 20' shown in fig. 2A and 2B, the substrate layer 15 is designed to be larger than the area where the contacts 25 and the first and second signal wires 111 and 121 are actually distributed. As shown in fig. 2A and 2B, the substrate layer 15 may be designed to have a shape close to an L-shape or a rectangular shape. Accordingly, the substrate layer 15 having a regular shape can reduce warpage that may occur when the entire substrate layer 15 expands and contracts unevenly due to temperature changes. Furthermore, when the signal transmission device is installed, the difference gradient between the interface of the electronic device and the signal transmission device is not easy to generate, so that the risk of instability or falling off is reduced. In addition, the shape is also beneficial to the alignment during the installation, the alignment procedure during the installation process is simplified, and the operability and the accuracy of the alignment are further improved.
It is to be noted that the above description of the shape of the substrate layer 15 is merely an example, and the present invention is not limited thereto. For example, to match openings, mounting areas, or gradient differences in the electronic devices to be mounted, the substrate layer 15 may also be contoured to match the mounting areas or eliminate possible gradient drops, consistent with the teachings of the present invention.
In the above embodiments, although the signal transmission devices 10, 20 and 20' respectively include four contacts 25 in the first connection area 100, the first connection block 210 of the second connection area 200, the second connection block 220 of the second connection area 200 and the third connection area 300, the invention is not limited thereto. For example, according to other embodiments of the present invention, the signal transmission devices 10, 20 and 20' may include one or more contacts at the first connection area 100, the first connection block 210 of the second connection area 200, the second connection block 220 of the second connection area 200 and the third connection area 300, respectively. In other embodiments according to the present invention, the first contact block 210 and the second contact block 220 may have different numbers of contacts.
Next, a signal transmission device 30 according to still another embodiment of the present invention will be explained with reference to fig. 3.
In the signal transmission device 30, the difference from the signal transmission device 10 shown in fig. 1 is that the second connection region 200 further includes a third contact block 230. In detail, the second connection area 200 includes a first contact block 210, a second contact block 220 and a third contact block 230 arranged in parallel. For example, the second connection region 200 may include 13 contacts 25 arranged in a row, and the first to fourth contacts 25 to 25 may be a first contact block 210, the fifth to ninth contacts 25 to 25 may be a second contact block 220, and the tenth to thirteenth contacts 25 to 25 may be a third contact block 230. Here, the first contact block 210 and the third contact block 230 each include four contacts 25, and the second contact block 220 includes five contacts, but this is merely an example, and the number of contacts of each contact block or connection region of the signal transmission device of the present invention is not limited to the number specifically recited herein.
Like the first contact block 210, the third contact block 230 is electrically connected to the first connection region 100 by the first signal wire 111, and is disposed on two sides of the second contact block 220 with the first contact block 210. In addition, the signal transmission direction of the third contact block 230 electrically connected to the first connection region 100 is away from the third contact block 230. However, the invention is not limited thereto, and the signal transmission direction of the third contact block 230 electrically connected with the first connection region 100 may also be into the third contact block 230. That is, the signal transfer direction of the first and third contact blocks 210 and 230 of the second connection area 200 may be the output and the second contact block 220 is the input, or the signal transfer direction of the first and third contact blocks 210 and 230 of the second connection area 200 may be the input and the second contact block 220 is the output. With this arrangement, the lateral relative position of the third attachment area 300 with respect to the second attachment area 200 can be adjusted to correspond to the desired system-end attachment position of the third attachment area 300.
Next, a signal transmission device 40 according to still another embodiment of the present invention will be explained with reference to fig. 4.
In the signal transmission device 40, the difference from the signal transmission device 30 shown in fig. 3 is mainly that the second connection region 200 further includes a fourth contact block 240. In detail, the second connection area 200 includes a first contact block 210, a second contact block 220, a third contact block 230 and a fourth contact block 240 arranged in parallel. For example, the second connection region 200 may include 16 contacts 25 arranged in a row, and the first to fourth contacts 25 to 25 may be a first contact block 210, the fifth to eighth contacts 25 to 25 may be a second contact block 220, the ninth to twelfth contacts 25 to 25 may be a third contact block 230, and the thirteenth to sixteenth contacts 25 to 25 may be a fourth contact block 240. Here, the first contact block 210 to the fourth contact block 240 each include four contacts 25, however, this is merely an example, and the number of contacts of each contact block or connection region of the signal transmission device of the present invention is not limited to the number specifically recited herein.
Like the second contact block 220, the fourth contact block 240 is electrically connected to the third connection region 300 through the second signal wire 121, and is disposed on two sides of the third contact block 230 with the second contact block 220. In addition, the signal transmission direction of the fourth contact block 240 electrically connected to the third connection area 300 is to enter the fourth contact block 240. However, the present invention is not limited thereto, and the signal transmission direction in which the fourth contact block 240 is electrically connected to the third connection region 100 may also be away from the fourth contact block 240. That is, the signal transfer direction of the first and third contact blocks 210 and 230 of the second connection area 200 may be the output and the second and fourth contact blocks 220 and 240 may be the input, or the signal transfer direction of the first and third contact blocks 210 and 230 of the second connection area 200 may be the input and the second and fourth contact blocks 220 and 240 may be the output. However, the embodiment described above with reference to fig. 4 is merely an example, and the present invention is not limited thereto. For example, the first contact block 210 to the fourth contact block 240 may be designed such that the signal transmission directions of the three contact blocks are the same, or may be designed to implement various input/output aspects according to the actual signal transmission requirement.
Next, a display device 1000 including the signal transmission device 20' shown in fig. 2B and a signal transmission method thereof will be described with reference to fig. 5A and 5B.
Referring to fig. 5A, the display device 1000 includes a display panel 400 having a first signal connection portion 1010, a control circuit 500 having a second signal connection portion 1020 and a processing device 1030 (e.g., an arithmetic processing chip), and a signal transmission device 20'. Wherein, the first end 11 of the first connection region 100 of the signal transmission device 20' is connected to the first signal connection portion 1010 for signal transmission; the second end 12 and the third end 13 of the second connection region 200 are connected to the second signal connection portion 1020 for signal transmission. In addition, the display device 1000 may further include a system 600 connected to the fourth end 14 of the third connection area 300, or the display device 1000 may be additionally connected to an external system 600 through the fourth end 14 of the third connection area 300. Here, the first terminal 11 can be directly connected to the first signal connecting portion 1010 or indirectly connected to the first signal connecting portion 1010 through the contact 25; the second terminal 12 and the third terminal 13 can be directly connected to the second signal connection portion 1020 or indirectly connected to the second signal connection portion 1020 through the contact 25; and the third terminal 13 may be directly connected to the system 600 or indirectly connected to the system 600 by a contact 25 or other signal connection, without being particularly limited to the configuration example shown in fig. 5A.
Under the above configuration, when the system 600 sends a signal through the fourth terminal 14, and the second signal connection portion 1020 receives an input signal from the second contact block 220 (i.e., one or more third terminals 13) and transmits the input signal to the processing device 1030 for processing, the processing device 1030 generates an output signal for transmission from the first contact block 210 (i.e., one or more second terminals 12) to the first terminal 11 of the first connection region 100 through the second signal connection portion 1020. For example, the external system 600 may input a gray-scale signal for displaying an image from the third connection area 300 of the signal transmission device 20', the gray-scale signal is input to the second contact block 220, the second signal connection portion 1020 connected to the second contact block 220 receives the gray-scale signal and transmits the gray-scale signal to the processing device 1030 to be processed into an image signal, and the generated image signal is transmitted from the first contact block 210 to the first connection area 100 through the second signal connection portion 1020 and received by the first signal connection portion 1010, so as to display a desired image on the display panel 400.
However, the signal transmission method described above is merely an example, and the signal transmission method of the display device 1000 including the signal transmission device 20' of the present invention is not limited thereto. For example, in the case that the display panel 400 is a touch-operable display panel 400, the capacitance-induced signal generated when the finger touches the display panel 400 may also be transmitted to the processing device 1030 sequentially through the first signal connection portion 1010, the first connection portion 100, the first end 11, the second end 12, the first contact block 210, and the second signal connection portion 1020, and the processing device 1030 converts the capacitance-induced signal into an operation signal and transmits the operation signal to another device of the external system 600 capable of executing the operation signal sequentially through the second signal connection portion 1020, the second contact block 220, the third end 13, the fourth end 14, and the third connection portion 300.
That is, when the second signal connection portion 1020 receives the input signal from the first contact block 210 and transmits the input signal to the processing device 1030 for processing, the processing device 1030 generates an output signal, and the output signal is transmitted from the second contact block 220 to the third connection area 300 through the second signal connection portion 1020.
Next, the integration of the simplified connection interface in the display device 1000 shown in fig. 5A will be described with reference to fig. 5B.
As shown in fig. 5B, in the display device 1000, the display panel 400, the control circuit 500 and the connection interface of the system 600 are integrated into one connection interface 150. The simplified connection interface is integrated, so that the design and installation between the whole display device and the corresponding signal transmission device become simpler. Here, the arrow direction represents an exemplary signal transmission direction, and the present invention is not limited to this illustrated example. In addition, in practical applications, the control circuit 500 and the signal transmission device 20' may be formed on the same substrate together, so as to save process steps and materials.
Hereinafter, a simplified connection interface integrated in a signal transmission apparatus and a display apparatus including the same according to other embodiments of the present invention will be described with reference to fig. 6A to 7B.
Fig. 6A to 6C illustrate a display device 2000 including the signal transmission device 30 shown in fig. 3 and a signal transmission method thereof. Here, the same or similar configuration as that described above with reference to fig. 5A and 5B will not be described again, and differences from fig. 5A and 5B will be mainly described hereinafter.
According to the above, the signal transmission device 30 further includes a third contact block 230 for connecting to the first connection region 100. As described above, when the display device 2000 is configured, the signal transmission between the display panel 400 and the control circuit 500 can be performed by the first contact block 210 and the third contact block 230 respectively, and the signal transmission is integrated with the connection interface 150 as in fig. 5A and 5B. Under this configuration, referring to fig. 6B, the signal transmission between the display panel 400 and the control circuit 500 can be performed in the same transmission direction by the first contact block 210 and the third contact block 230, respectively. In addition, referring to fig. 6C, the signal transmission between the display panel 400 and the control circuit 500 may also be performed in different transmission directions by the first contact block 210 and the third contact block 230, respectively. For example, fig. 6C shows a state where the gray-scale signal input from the system 600 is processed to be an image signal, and the image signal is transmitted to the display panel 400 and the capacitive sensing signal is received from the display panel 400. In addition, the display device 2000 shown in fig. 6A may also include other signal transmission directions, and the above is only an example.
Fig. 7A to 7C illustrate a display device 3000 including the signal transmission device 40 shown in fig. 4 and a signal transmission method thereof. Here, the same or similar configuration as that described above with reference to fig. 6A to 6C will not be described again, and differences from fig. 6A to 6C will be mainly described hereinafter.
According to the above, the signal transmission device 40 further includes a fourth contact block 240 for connecting the third connection area 300. As described above, when the display device 3000 is configured, the signal transmission between the system 600 and the control circuit 500 can be performed by the second contact block 220 and the fourth contact block 240 respectively, and as shown in fig. 6A to 6C, the signal transmission is integrated in the connection interface 150. Under this configuration, referring to fig. 7B, signal transmission between the display panel 400 and the control circuit 500 may be performed in the same transmission direction by the first contact block 210 and the third contact block 230, respectively, and signal transmission between the system 600 and the control circuit 500 may be performed in the same transmission direction by the second contact block 220 and the fourth contact block 240, respectively. At this time, the signal transmission direction between the display panel 400 and the control circuit 500 is different from or opposite to the signal transmission direction between the system 600 and the control circuit 500.
In addition, referring to fig. 7C, the signal transmission between the display panel 400 and the control circuit 500 may also be performed in different transmission directions by the first contact block 210 and the third contact block 230, respectively, and the signal transmission between the system 600 and the control circuit 500 may also be performed in different transmission directions by the second contact block 220 and the fourth contact block 240, respectively. For example, fig. 7C shows a state in which a gray-scale signal is input from the system 600, processed, and then converted into an image signal, and then transmitted to the display panel 400, and a capacitive sensing signal is received from the display panel 400, processed, and then converted into an operation signal, and then transmitted to the system 600. In addition, the display device 3000 shown in fig. 7A may also include other signal transmission directions, and the above is only an example.
Next, another embodiment of the signal transmission device and the display device including the same according to the present invention will be described with reference to fig. 8 and 9.
Referring to fig. 8, the display device 4000 may include the display panel 400, the control circuit 500, and the system 600 disposed parallel to each other but not on the same plane. For example, the display panel 400, the system 600, and the control circuit 500 may be respectively disposed in parallel according to a gravity direction, wherein the display panel 400 may partially overlap with the system 600 and be staggered from the control circuit 500 when the surface of the display panel 400 is viewed from the gravity direction. In view of the above, the signal transmission device 20' shown in fig. 2B can simultaneously connect the display panel 400, the control circuit 500 and the system 600 arranged above and below through bending and bending, thereby achieving substantially the same or similar connection configuration on a three-dimensional level as shown in fig. 5A. That is, one end of the signal transmission device 20' can be connected to the display panel 400, the other end is connected to the system 600, and the control circuit 500 is connected to the second connection region disposed in the middle. Here, the signal transmission device 20' may be a flexible printed circuit board, and details thereof that have been specifically described in the above embodiments are omitted for convenience of describing the three-dimensional structure.
Referring to fig. 9, in a display device 5000 according to another embodiment of the present invention, a signal transmission device 90 may be implemented in combination with a specific three-dimensional structure.

In the display device 5000, the system 600 has an opening 75 at one side or corner of the system, thereby exposing the back surface 401 of the underlying display panel 400.
In this embodiment, the signal transmission device 90, which may be a flexible printed circuit board according to an embodiment of the present invention, is designed in a U shape, the first connection region 100 and the third connection region 300 are respectively located at two ends of the U shape, and the first contact block 210 and the second contact block 220 of the second connection region 200 are located at a turning point of the U shape. For example, the second connection region 200 may include contacts 25 arranged in a row, and the first to second contacts 25 to 25 may be a first contact block 210, and the third to fourth contacts 25 to 25 may be a second contact block 220. Further, the contact 25 located in the first contact block 210 may be connected to the first connection region 100 through the first signal wire 111, and the contact 25 located in the second contact block 220 may be connected to the third connection region 300 through the second signal wire 121.
Here, the first connection region 100 of the U-shaped signal transmission device 90 may be coupled to the rear surface 401 of the display panel 400 exposed by the opening 75 (i.e., to a specific signal processing device, circuit or element disposed on the rear surface 401 of the display panel 400), the second connection region 200 may be additionally connected to the separate control circuit 500, and the third connection region 300 may be directly coupled to the system 600 on the rear surface 401 of the display panel 400, thereby accomplishing a stereoscopic configuration and achieving the purpose of integrating different connection interfaces to improve the configuration of the signal transmission device in conformity with the spirit of the present invention.

Then, the image signal is outputted from the first contact block 210 of the second connection area 200 to the first connection area 100 through the first signal wire 111, and then received by a specific signal processing device, circuit or element on the back surface 401 of the display panel 400, and even further processed to display a desired image on the display surface 402 of the display panel 400. However, the signal transmission directions described herein are merely examples, and the signal transmission direction of the display apparatus 5000 according to the embodiment shown in fig. 9 may have various changes as in the other embodiments described above.
It is to be noted that, in the display device described above with reference to fig. 8 to 9, details that have been specifically described in the other embodiments are omitted for convenience of describing different stereoscopic configurations.
