This application claims priority to Chinese Patent Application No. 201610128661.1, filed on Mar. 7, 2016, the entire contents of which are incorporated herein by reference.
The present disclosure relates to the field of audio-visual equipment, and in particular, to a TV main board apparatus and a TV system.
In a conventional TV, the main board is generally integrated in the TV's rear casing.
As is evident from the above, in prior art, the TV main board is integrated in the TV's rear casing. Since there are many external ports on the main board, the TV's rear casing has to allow many leading-out wires that connect to external devices (see
In the prior art, there is an approach to the above problem: placing the TV main board outside the TV casing as an independent apparatus. But the approach makes it necessary to provide both the TV and the main board with a respective power supply line and provide a line to connect the TV to the main board. The complicated wiring leads to still inconvenient use and installation, and complicated and unsightly appearance.
In order to solve the above problems in the prior art, the present disclosure provides a TV main board apparatus and a TV system, which can be used and installed with more ease.
According to one aspect of the present disclosure, there is provided a TV main board apparatus, which comprises: a casing having at least one opening; a TV main board accommodated in the casing; a first interface exposed outside the casing via the opening, wherein the first interface is capable of connecting to a power supply so as to receive first electric power; a second interface exposed outside the casing via the opening, wherein the second interface is capable of connecting to a TV so as to transmit a multimedia signal from the TV main board and the first electric power to the TV and receive second electric power from the TV so as to supply the second electric power to the TV main board; and an interface connecting device configured to connect the first interface to the second interface so as to transmit the first electric power therebetween.
According to another aspect of the present disclosure, there is provided a TV system, which comprises the above TV main board apparatus, a connection apparatus, and a TV, wherein the connection apparatus connects the TV main board apparatus to the TV.
In each of the aspects of the present disclosure, the TV main board as an independent apparatus is separated from the TV, so the TV does not need to have a large number of leading-out wires, and the TV main board can be repaired and replaced with ease. Besides, in each of the aspects of the present disclosure, it is unnecessary to provide the TV and the main board with independent power supply lines. Instead, only connecting the first interface of the TV main board to a power supply and connecting the second interface to the TV make it possible to supply electric power to both the TV main board apparatus and the TV and transmit a signal therebetween. As a result, the whole system becomes less complicated, easier to use and install, and simple and attractive in appearance.
Additional features and aspects of the present disclosure will become apparent from the following description of exemplary examples with reference to the attached drawings.
The drawings, which are incorporated in and constitute part of the specification, together with the description, illustrate exemplary examples, features and aspects of the present disclosure and serve to explain the principles of the present disclosure.
a and 5b are schematic structural diagrams showing examples of an interface connecting device.
Various exemplary examples, features and aspects of the present disclosure will be described in detail with reference to the drawings. The same reference numerals in the drawings represent parts having the same or similar functions. Although various aspects of the examples are shown in the drawings, it is unnecessary to proportionally draw the drawings unless otherwise specified.
Herein the term “exemplary” means “used as an instance or example, or explanatory”. An “exemplary” example given here is not necessarily construed as being superior to or better than other examples.
Numerous details are given in the following examples for the purpose of better explaining the present disclosure. It should be understood by a person skilled in the art that the present disclosure can still be realized even without some of those details. In some of the examples, methods, means, units and circuits that are well known to a person skilled in the art are not described in detail so that the principle of the present disclosure become apparent.
This example separates a TV main board as an independent apparatus from a TV, so the TV does not need to have a large number of leading-out wires, and the TV main board can be repaired and replaced with ease. In this example, it is unnecessary to provide the TV and the main board with separate power supply lines. Instead, the TV main board apparatus is capable of supplying the first electric power to the TV via the second interface so as to supply electric power to the TV and receiving the second electric power from the TV via the second interface so as to supply electric power to itself. That way, only connecting the first interface to a power supply and connecting the second interface to the TV make it possible to supply electric power to both the TV main board apparatus and the TV and transmit a signal therebetween. As a result, the whole system becomes less complicated, easier to use and install, and simple and attractive in appearance.
As an example of the casing, the casing 201 may be in any desired shape such as a cuboid or a cube. The present disclosure is not intended to place any restrictions on the shape of the casing. The opening primarily serves to expose an interface (e.g., a power supply interface, an audio/video interface, a cable television interface, or a USB interface) that is within the casing outside the casing, and accommodate various components such as press keys, a remote-control signal receiver, and a display. The use, shape, number, location and the like of the opening may be decided in light of actual needs, and are not restricted by the present disclosure.
As an example, the opening accommodating the first interface 203 and the opening accommodating the second interface 204 may be located on the same side of the casing 201. However, the openings may be located on other parts of the casing (e.g., two opposite sides of the casing). The present disclosure is not intended to place any restrictions on the location.
The first interface 203 is connectable to a power supply so as to receive the first electric power. As an example of the first electric power, it may be AC power of 220V.
The second interface 204 is connectable to the TV so as to transmit the multimedia signal and the first electric power to the TV and receive the second electric power from the TV. As an example, the multimedia signal may be a multimedia signal input externally or a multimedia signal that is converted by the TV main board from a built-in signal (e.g., an audio signal, a video signal or a text) of the TV main board apparatus. Such a multimedia signal may be, for instance, a high definition multimedia interface (HDMI) signal.
As an example, the second electric power may be converted from the first electric power by the TV. For instance, it may be DC power obtained by performing an AC-DC conversion of AC power of 220V. The second electric power may serve to power the TV main board apparatus. The voltage of the second electric power may be set as the TV main board apparatus needs for power, such as 5V.
As an example, the first interface may have a terminal configured to transmit the first electric power, such as a live wire terminal and a neutral wire terminal.
As an example, a terminal configured to transmit the first electric power, a terminal configured to transmit the second electric power, and a terminal configured to transmit the multimedia signal may be integrated in the second interface 204. Due to such integrated configuration, only one line is needed between the TV main board apparatus and the TV, making it possible to supply electric power to both the TV main board apparatus and the TV and transmit the multimedia signal therebetween. As a result, the whole system looks simple and attractive and is easy to use and install.
As an example of the second interface 204, the terminal configured to transmit the second electric power and the terminal configured to transmit the multimedia signal are conductively connectable to the TV main board, and the terminal configured to transmit the first electric power is conductively connectable, via the interface connecting device 205, to a terminal of the first interface 203 that is configured to transmit the first electric power and is electrically isolated from the TV main board 202. That way, the first electric power does not pass through the TV main board, thereby avoiding interference with the main board's operation and even damage to the main board.
As an example, the first interface 203 may be a plug interface (also known as male connector), and the second interface 204 may be a socket interface (also known as a female connector). Consequently, after the first interface 203 connects to the first electric power, the second interface as the female connector would not have its conductive portions (e.g., its terminals) exposed outside, thus ensuring safety.
As an example, the terminals of the first interface 203 and those of the second interface 204 can be fixed at their respective seats, the seat of the first interface 203 can be fixedly connected to the casing 201. The seat of the second interface 204 can be fixedly connected to the casing 201 or to the TV main board 202.
As an example, the second interface may have an HDMI. The HDMI may have more than 19 pins, and for instance, preferably 29 or 30 pins. A part of the pins (e.g., 13 pins, or any other number as needed) may serve to transmit a high definitional multimedia signal, and another part of the pins (e.g., 6 pins, or any other number as needed) may serve to transmit the second electric power (e.g., DC power of 5V). Some of the pins may serve to transmit a control signal or any other desired signal.
The terminals of the second interface may be arranged in the form of an array of any profile in light of needs.
The second interface 204 may further have a live wire terminal and a neutral wire terminal that are configured to transmit the first electric power (e.g., electric power of 220V).
Besides, the location relationship between the HDMI and the live wire and neutral wire terminals, and the profile of the second interface may be decided by a person skilled in the art in light of actual needs. The present disclosure is not meant to place restrictions on them.
a and 5b are schematic structural diagrams showing examples of an interface connecting device.
The connection apparatus exemplified as such integrates the transmission of a multimedia signal, the transmission of first electric power and the transmission of second electric power with each other. In appearance, only one connection line makes it possible to supply electric power to both a TV and a TV main board apparatus and transmit a multimedia signal. As a result, the whole system becomes less complicated, easier to use and install, and simple and attractive in appearance.
For more details of the first electric power, second electric power and multimedia signal, Example 1 could be referred to.
As an example, the first connection section 802 can be compatible with and connectable to the second interface 204 of the TV main board apparatus in Example 1. The second connection section 803 can be compatible with and connectable to the corresponding interface of the TV.
As an example, a terminal configured to transmit the first electric power, a terminal configured to transmit the second electric power, and a terminal configured to transmit the multimedia signal may be integrated in the first connection section 802 and second connection section 803 respectively. Correspondingly, the connection line 801 may comprise a connection line configured to transmit the first electric power, a connection line configured to transmit the second electric power, and a connection line configured to transmit the multimedia signal.
For instance, the first and second connection sections may be of configuration similar to that shown in
It should be understood by a person skilled in the art that
Each of the transmission lines in the connection line may correspond to and conductively connect to each of the terminals of the first and second connection sections.
The TV exemplified as such does not have a built-in TV main board. Instead, the TV main board apparatus is independent of the TV, so the TV does not need to have a large number of leading-out wires, and the TV main board can be repaired and replaced with ease. Besides, in this example, the transfer apparatus serves to supply electric power to both the TV and the TV main board apparatus and transmit a multimedia signal. That way, when the TV is to be used, it only needs to connect to the TV main board apparatus and does not need additional power cords. As a result, the whole system becomes less complicated, easier to use and install, and simple and attractive in appearance.
For more details of the first electric power, second electric power and multimedia signal, Example 1 could be referred to.
As an example of the power supply board 1002, it may convert the first electric power into fourth electric power for powering the transfer apparatus. For instance, the fourth electric power may be obtained by performing an AC-DC conversion of AC power of 220V (the first electric power). The voltage of the fourth electric power may be set as the transfer apparatus needs for power, such as 12V.
As an example, the power supply board 1002 may include an AC-DC converter that converts the first electric power into the second or fourth electric power.
As an example, the backlight system of the TV may be a backlight bar. In this case, the third electric power may be a driving voltage for the backlight bar. The voltage of the third electric power may be decided by a person skilled in the art in light of actual application scenarios.
As an example, the TV may further comprise a time sequence controller (T-CON). The transfer apparatus may provide the T-CON with a multimedia signal (e.g., a video signal) so as to drive a display to display the multimedia signal. The transfer apparatus may comprise, for instance, a V-by-One (VBO, a signaling standard) interface, or a 51 Pin low voltage differential signaling (LVDS) interface, so as to supply a multimedia signal to the T-CON.
As an example, the transfer apparatus 1001 may further comprise an interface component. The interface component can be compatible with and connectable to the second connection section 803 of the above connection apparatus. A terminal configured to transmit the first electric power, a terminal configured to transmit the second electric power, and a terminal configured to transmit the multimedia signal may be integrated in the interface component. The interface component may be of configuration similar to that shown in
