Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a power supply apparatus and a display apparatus having the power supply apparatus.

In homes, offices, etc., people use electrical appliances such as televisions, fans, air conditioners, audio, computers, and so on. Such electric devices can be remotely controlled by a remote controller developed for the convenience of the user.

An electrical device is in standby mode when not in use while connected to a commercial AC power source, where the electrical device can not be completely isolated from the utility power source and thus consumes hundreds of mW or a few W of standby power. This standby power accounts for 11% of the household power consumption.

Particularly, an electric appliance that performs communication with a remote controller consumes a certain amount of standby power in order to receive a signal of the remote controller in the standby mode, and therefore requires a technique for reducing standby power.

Further, a technique for saving standby power is required for a display device in which a standby mode is operated for a long time, power consumption is high even during driving time, and various kinds of power sources are required.

Accordingly, various technologies are being developed to reduce standby power.

Among them, there are technologies using a switching mode power supply (SMPS) and a technique using a secondary battery.

In this case, the standby power is very small, but there is still a problem of consuming power because the SMPS internal transformer is continuously driven to supply the standby power. In addition, the transformer of SMPS supplies much lower power than rated power, so there is a problem that its efficiency is reduced.

A technique using a secondary battery is a technique of charging the secondary battery with electric power and using the electric power stored in the secondary battery in the standby mode as standby power.

In this case, the standby power can be removed, but there is a limitation in the amount of charge of the secondary battery. Therefore, there is a problem that the secondary battery is discharged after a certain period of time. Further, There is a problem that needs to be installed additionally.

The second switching unit 133 is turned on or off based on the control signal transmitted from the first control unit 139 and supplies the voltage adjusted by the voltage adjustment unit 132 to the first power conversion unit 134, .

More specifically, the second switching unit 133 is turned on so that standby power is supplied to the load 200 when the current mode of the load 200 is the normal mode.

This is because power is continuously supplied to the receiver for receiving the signal of the remote controller and the input for receiving the ON signal of the power button even when the load is in the normal mode.

The second switching unit 133 switches on and off driving based on the voltage of the charging unit 136 when the current mode of the load 200 is the standby mode.

The second switching unit 133 is turned on when the current mode is set to the standby mode and the charging unit 136 is charged when the voltage of the charging unit 136 during standby power supply to the load 200 is discharged below the first reference voltage. And is turned off in response to a command from the first control unit 139 when charging of the charging unit 136 is completed.

Here, the first reference voltage and the second reference voltage are set in advance.

In one example, when the current mode of the load is the normal mode, the power-saving power source unit 130 maintains the second switching unit 133 in the on-drive state, And if the current mode of the load is the standby mode, the charging unit 136 switches the second switching unit 133 and the third switching unit 135 to ON and OFF based on the voltage of the charging unit 136, To the load by the standby power.

If the voltage of the charging unit 136 is lower than the first reference voltage in a state where the current mode of the load is the normal mode, the power saving unit 130 turns on the third switching unit 135 to turn on the charging unit 136 It is also possible to charge the power.

Here, the communication unit performs communication with a nearby terminal through at least one of infrared communication, zigbee communication, radio frequency (RF) communication, and Bluetooth communication, or communicates with a remote terminal using a Wi-Fi It is possible.

That is, the second control unit 211 grasps a user command on the basis of the operation contents of the user transmitted from the remote control 2, controls the driving of the display panel 300 according to the user command, And controls the communication unit to control the Internet connection when the Internet request signal is received.

If the standby power is input from the second power conversion unit 159c, the second control unit 211 determines whether the standby mode is the deep sleep mode based on whether the standby power is maintained or not. If the standby mode is the deep sleep mode, The fourth switching unit 159c and the fifth switching unit 170 controls the on-driving of the fourth switching unit 159c and the fifth switching unit 170 so that the sleep mode is maintained in the sleep mode, It is also possible to maintain and control the off-driving of the switching element 170.

At this time, if the input of the standby power is maintained, the second controller 211 determines that the standby mode is the sleep mode and maintains the sleep mode. If the standby power is re-inputted, the second control unit 211 determines the standby mode as the deep sleep mode Controls the current mode to normal mode.

The second receiving unit 212 receives the power-off signal and the driving operation signal from the remote controller 2 in the normal mode.

The second receiving unit 212 receives standby power from the second power converting unit 155 when the standby mode is controlled to the sleep mode. That is, the second receiver 212 maintains the standby state in order to receive the power-off signal from the remote controller 2 in the control mode in the sleep mode.

The second receiving unit 212 does not perform the driving because the power supplied from the second power converting unit 159b is shut off during the control in the deep sleep mode.

The second receiving unit 212 receives the driving power from the second power converting unit 159b and receives the power-off signal and the driving operation signal from the remote controller 2 in the control in the normal mode.

At this time, the second receiving unit 212 receives the deep sleep mode or the sleep mode selection signal transmitted from the remote controller 2. [

The storage unit 213 stores updated and updated information in the normal mode and the sleep mode.

The light source unit (LED) 220 includes a plurality of light emitting diodes (LEDs) 220 disposed on a side or rear surface of a light guide plate (not shown) and driven according to a command of the second control unit 211 to output light to the light guide plate.

The remote controller 2 will be described in detail with reference to Fig.

The remote controller 2 is remotely located from the display device 1. [

The remote controller 2 is wirelessly connected to the display device 1 and is operated by a user to transmit a drive on-off signal and a drive control signal to the display device 1. [

The input unit 21 is operated by the user and transmits the operated signal to the third control unit 22. [ The input unit 21 includes a power key 21a for instructing power on or off and an operation key 21b for controlling the driving of the display device 1 and a signal corresponding to each key to a third control unit 22).

The power key 21a may be composed of two. At this time, one power key is a key for releasing the deep sleep mode, and the other power key is a key for releasing the sleep mode.

The input unit 21 is selected as a sleep mode or a deep sleep mode.

The third control unit 22 controls the driving of the first transmission unit 23 so that the on / off signal of the power key 21a transmitted from the input unit 21 is transmitted.

If there are two power keys, a code corresponding to each power key is generated and output.

The third control unit 22 generates a code corresponding to the operation signal of the operation key 21b transmitted from the input unit 21 and drives the second transmission unit 24 to transmit the drive control signal having the generated code .

The third control unit 22 controls the transmission of the signal corresponding to the selected sleep mode or the deep sleep mode.

The first and second transmitting units 23 and 24 comprise a light generating unit or an RF generating unit and transmit a signal having a code corresponding to the instruction of the third controlling unit 22. [

The first transmitting unit 23 transmits a signal corresponding to switching to the normal mode or switching to the deep sleep mode. At this time, the signal of the first transmitting unit 23 is received by the first receiving unit 157.

The second transmitting unit 24 transmits a signal corresponding to the switching to the normal mode or the switching to the sleep mode and also transmits the driving control signal in the normal mode.

The second transmitting unit 24 transmits a signal corresponding to the sleep mode or the deep sleep mode.

At this time, the signal of the second transmitting unit 24 is received by the second receiving unit 212.

The power supply corresponding to the signal transmitted from the remote controller 2 and the driving of the load will be described with reference to Figs. 9 to 12. Fig.

9 is a driving power flow chart between the power supply and the load when the display device 1 is performed in the normal mode.

An example of switching the display device from the deep sleep mode to the normal mode will be described.

The power supply switches the state of the display device from the standby mode to the normal mode when a signal input via the remote controller 2 is input. At this time, the power supply turns on the first switching unit 120.

The AC power of the input power source 110 is applied to the second rectifying part 152 regardless of the ON drive of the first switching part 120 and the AC power applied to the second rectifying part 152 is rectified, And converts the power applied to the first power conversion unit 153 into power for charging and outputs the power to the charging unit 155. [

If the charging unit 155 is in the buffered state, the second switching unit 154 is controlled to be turned off. If the charging unit 155 is in the discharging state, the second switching unit 154 is turned on, So that electric power is applied to the charging unit 155.

The first receiving unit 157 and the first controlling unit 158 are driven by the power supplied from the charging unit 155. The first control unit 158 driven by the power of the charger 155 maintains the first switching unit 120 in the ON state.

That is, the first standby power unit 150a supplies the driving power to each component by performing charging and discharging of the charging unit 155. [

The AC power of the input power source 110 is applied to the first and third rectifying sections 161 and 159a through the first switching section 120 by turning on the first switching section 120. [

Next, the third rectifying unit 159a rectifies the inputted external AC power, and outputs the rectified power to the second power converting unit 159b.

The second power conversion unit 159b converts the power to a predetermined level of the rectified power and outputs the converted power to the second control unit 211 via the second standby power output stage 159d. Here, the second standby power output terminal 159d of the second power conversion unit 159b and the second control unit 211 are electrically connected to each other.

When the power is inputted through the second standby power output terminal 159d of the second power conversion unit 159b, the second control unit 211 checks the mode stored in the storage unit 213 and determines whether the confirmed mode is the deep sleep mode . At this time, if the verified mode is the deep sleep mode, the fourth and fifth switching units 159c and 170 are turned on.

Thus, the power converted by the second power conversion unit 159b is output through the first standby power output stage 159d, and the power factor improving unit 162 is also turned on.

At this time, by turning on the power factor improving unit 162, the first rectifying unit 161 and the driving power converting unit 163 can be electrically connected.

That is, the first rectifier 161 rectifies the AC power of the input power source 110. This rectification converts AC power into DC power.

The power rectified by the first rectifying unit 161 is corrected by the power factor improving unit 162 because the first rectifying unit 161 is electrically connected to the driving power converting unit 163 and then the driving power converting unit 163 .

The driving power conversion section 163 converts the power whose power factor is corrected to a power of a certain level and supplies the converted power to the load 200. [ In other words, the output terminal of the drive power conversion section 163 is connected to various loads.

The second controller 211 turns on the sixth switch 180 and communicates with the first controller 158. In addition, the second controller 211 turns on the sixth switching unit 180 when the sleep mode is selected.

As described above, the second standby power unit 150b receives AC power from the input power source 110 because the first switching unit 120 is on-driven, rectifies and converts the supplied power, As shown in Fig.

In addition, when switching from the normal mode to the standby mode, an OFF signal can be transmitted to the first receiving unit 157 or an OFF signal can be transmitted to the second receiving unit 212 according to the power key operation of the remote control 2. [ At this time, it is possible to switch to the deep sleep mode when the OFF signal is received through the first receiver 125, and to switch to the sleep mode when the OFF signal is received through the second receiver 212. [

Also, when the second control unit 211 deactivates the first receiving unit 157 in the normal mode, the second control unit 211 may transmit the switching command to the first control unit 158 to the standby mode.

Also, when an OFF signal is received to the second receiving unit 212, the second control unit 211 may transmit the switching command to the first control unit 158 to the standby mode.

10 is a driving power flow chart between the power supply and the load when the display device 1 is performed in the deep sleep mode.

The power supply switches the state of the display device from the normal mode to the standby mode when an OFF signal is input via the remote controller 2. [ At this time, the mode stored in the storage unit 213 is checked, and if the verified mode is the deep sleep mode, the standby mode of the display device is controlled to the deep sleep mode.

First, the power supply turns off the first switching unit 120.

As a result, the power supplied from the input power source 110 to the load 200 is cut off, and the second standby power unit 150b does not generate power. That is, the components in the 'A' area are not driven.

In addition, regardless of the off-driving of the first switching unit 120, the first standby power unit 150a performs charging / discharging of the charging unit 155 to supply driving power to the respective components.

More specifically, the AC power of the input power source 110 is applied to the second rectifying part 152, the AC power applied to the second rectifying part 152 is rectified and then output to the first power converting part 153, The power applied to the first power conversion unit 153 is converted into electric power for charging and then output to the charging unit 155. [

If the charging unit 155 is in the buffered state, the second switching unit 154 is controlled to be turned off. If the charging unit 155 is in the discharging state, the second switching unit 154 is turned on, So that electric power is applied to the charging unit 155.

The first receiving unit 157 and the first controlling unit 158 are driven by the power supplied from the charging unit 155. The first control unit 158 driven by the power of the charger 155 maintains the first switching unit 120 in the ON state.

In this way, the first standby power unit 150a supplies standby power to the first control unit 158 and the first receiving unit 157 by performing charging and discharging of the charging unit 155. At this time, the first control unit 158 And controls the charging of the charging unit 155 based on the voltage of the charging unit 155. [

11, the power supply compares the detected voltage with a reference voltage, and keeps the second switching unit 154 in the off state when the detected voltage is equal to or higher than the reference voltage, while if the detected voltage is lower than the reference voltage The second switching unit 154 is turned on to allow the charging unit 155 to be charged and the voltage of the charging unit 155 is re-detected while the charging unit 155 is being charged to compare the re-detected voltage with the buffer voltage, If the detected voltage is equal to or higher than the buffering voltage, the second switching unit 154 is turned off to stop charging.

It can be seen that the power of the charger 155 is increased when the second switching unit 154 is turned on and the power of the charger 155 is discharged as time elapses.

The charging unit 155 supplies an average of 4 mW of power to the first control unit 158 and the first receiving unit 157 as standby power and notifies that the charging is performed when the power of the charging unit is maintained at a minimum power of 2 mW for a predetermined time .

If the power-on signal of the remote control 2 is received by the first receiving unit 157 during the deep sleep mode, the first receiving unit 157 transmits a power-on signal to the second controlling unit 211. [ At this time, the first control unit 158 turns on the first switching unit 120 so that the AC power of the input power source 110 is applied to the second and third rectifying units 150 and 170, and then the third and fourth switching units 160 And 165 are turned on to output the converted power through the second power conversion unit 159b and the driving power conversion unit 163. [

12 is a flow chart of driving power between the power supply and the load when the display device 1 is performed in the sleep mode.

The power supply turns on the first switching unit 120 in the sleep mode.

In addition, regardless of the on-driving of the first switching unit 120, the first standby power unit 150a may supply the driving power to the first control unit and the first receiving unit 157 by performing charging and discharging of the charging unit 155 , The first receiving unit 157 is deactivated because it is performing the sleep mode.

Therefore, the on-signal of the remote controller for releasing the standby mode can be received through the second receiver.

The AC power of the input power source 110 is applied to the first and third rectifying sections 161 and 159a through the first switching section 120 by turning on the first switching section 120. [

Next, the third rectifying unit 159a rectifies the inputted external AC power, and outputs the rectified power to the second power converting unit 159b.

The second power conversion unit 159b converts the power to a predetermined level of the rectified power and outputs the converted power to the second control unit 211 through the second output stage 159d. Here, the second output terminal 159d of the second power conversion unit 159b and the second control unit 211 are electrically connected to each other.

When the power is inputted through the second output terminal 159d of the second power conversion unit 159b, the second control unit 211 checks the mode stored in the storage unit 213 and determines whether the confirmed mode is the deep sleep mode .

At this time, if the determined mode is the sleep mode, the second controller 211 controls the sixth switch 180 to maintain the inactive state of the first receiver 157 and maintain the on state of the first switch 120, (158).

If the signal from the remote controller 2 is not received while the confirmed mode is the sleep mode, the second controller 211 keeps the third and fourth switching units 160 and 165 in the off state, So that the converted power is not outputted through the power conversion units 155 and 180. That is, the components in the 'B' region are not driven.

If the power-on signal of the remote controller 2 is received by the second receiver 212 during the sleep mode, the second receiver 212 transmits a power-on signal to the second controller 211. At this time, the second control unit 211 turns on the fourth switching unit 159c and the fifth switching unit 170 so that the converted power is outputted through the second power conversion unit 159b and the driving power conversion unit 163 do.

The power output of the second power converting unit 159b and the driving power converting unit 163 according to the on-driving of the fourth switching unit 159c and the fifth switching unit 170 is the same as that described with reference to FIG. 10

13 is a detailed configuration diagram of a power supply according to another embodiment.

The power supply 100 according to another embodiment includes an input power source 110, a first switching unit 120, a power saving power source unit 150, and a driving power source unit 160.

The power supply according to another embodiment performs the standby mode and the normal mode.

Here, the standby mode includes only the deep sleep mode.

The first control unit 158 controls the first switching unit 120 in the deep sleep mode and turns on the first switching unit 120 in the sleep mode and the normal mode. This causes power supplied to the load to be cut off in the deep sleep mode, and power is supplied to at least one load in the normal mode and the sleep mode.

The first control unit 158 compares the voltage of the charging unit 155 with the first reference voltage and turns on the second switching unit 154 when the voltage of the charging unit 155 is less than the first reference voltage, The second switching unit 154 is turned off.

The first receiving unit 157 receives power from the charger 155 and waits for reception of a power on / off signal transmitted from the remote controller 2 while performing a deep sleep mode.

The first standby power unit 150a generates standby power using the power on the primary side before the power conversion based on the second power conversion unit 159b and the driving power conversion unit 163, 150b generate drive power using the power of the secondary side after the power conversion based on the second power conversion section 159b and the drive power conversion section 163.

As described above, the standby power can be zeroized by supplying the electric power charged to the super capacitor serving as the charging unit 155 with the driving power of the first receiving unit 157 and the first control unit 158 for receiving the on / off signal of the remote controller .

A brief description of the load supplied from the power supply according to another embodiment is as follows.

The second control unit 211 receives the power converted by the second power conversion unit 159b in the normal mode and controls the fourth switching unit 159c and the fifth switching unit 170 to control the second power conversion unit And the driving power conversion unit 163 are supplied to the driving unit 230, the light source unit 220, the second control unit 211, and the second receiving unit 212, respectively.

The second control unit 211 controls driving of the driving unit 230 and the light source unit 220 based on a driving command transmitted from the second receiving unit 212 in the normal mode.

The second controller 211 controls the fourth switch 159c and the fifth switch 170 to turn on the deep sleep mode when the power is re-inputted while the power is off . So that the power converted by the second power converting unit 159b and the driving power converting unit 163 is supplied to the driving unit 230 and the light source unit 220.

The second controller 211 maintains the sleep mode when the standby power is continuously inputted through the second power converter.

Although the display device of the present embodiment has been described as an example, the present invention can be applied to electric devices that receive power on / off and drive commands through a remote controller.
