Description

A monitor apparatus for saving the power by analyzing the matrix of the headline information and the method for controling the same}

The present invention relates to a power-saving monitor device and a control method thereof. In particular, the brightness of a monitor is easily controlled by analyzing the type of a program currently being executed in a simple manner through a matrix value analysis for the headline of a currently running program. Thus, it relates to a monitor device and a control method for reducing the total consumed energy.

In general, the power consumption of a computer is reduced by turning off the screen in the standby mode (power saving mode) or the monitor power off mode while in use. At this time, the monitor screen is turned off, but the power to the monitor is continuously supplied to consume power. That is, standby power is continuously supplied to the control board of the monitor even when the screen is turned off, resulting in unnecessary standby power consumption.

Therefore, various studies have been conducted to prevent power waste by cutting off the power supply without removing the plug for supplying commercial power to the monitor. As an example, Korean Patent Publication No. 2013-0109060 ( The prior art disclosed in Standby Power Blocking Device) has a power switching unit at the front end of which power is supplied to the computer, and when the computer is turned off, power of the computer as well as the peripheral device (monitor) is cut off to cut off standby power.

That is, a power switching unit 20 that receives external commercial power and provides operating power for each internal component of the computer, an outlet power switching unit 19 for shutting off/supplying power to peripheral devices, and a peripheral device outlet ( 18), and when the computer enters the standby mode (power saving mode), the power outlet power switching unit 19 is controlled using the memory power to cut off power (AC power) supplied to the computer peripheral devices. Through this process, standby power is blocked to prevent waste of power saving.

However, the first prior art has the advantage of preventing power waste of peripheral devices when the computer is turned off or in a power saving mode, but the power switching unit 20, the power outlet power switching unit 19, and the peripheral device receptacle ( 18) has to be built-in, so the configuration of the computer is complicated, and the cost of implementing a device for power saving is high, so it is difficult to easily apply it to a real computer and peripheral devices.

As a second prior art for solving this problem, Korean Patent Publication No. 2015-0123435 (monitor standby power blocking device through computer interlocking) is disclosed. It automatically cuts off standby power of the monitor by using the VGA signal, and automatically supplies power to the monitor when the computer is running, minimizing the user's operation and improving the convenience. It provides a monitor standby power cut-off device through computer interlocking. will be.

That is, the second conventional technology allows the monitor to block standby power by using only the VGA signal transmitted from the existing computer to the monitor without adding a separate configuration for blocking the standby power of the monitor from the computer. It is to provide a monitor power cut-off device through a computer linkage to simplify the configuration to cut off the standby power of the device and to minimize the device implementation cost.

This will be described in detail with reference to FIGS. 2 and 3, and as shown in FIG. 2, the monitor standby power cutoff device through a computer linkage according to the second prior art includes an input device 10, a computer main body 100, and a monitor. Includes 200. The computer main body 100 serves to generate a digital interface signal (DVI signal) for controlling standby power of the monitor 200 and transmit it to the monitor 200. The computer main body 100 is an input/output board 110 that interfaces the input signal of the input device 10, a power supply unit 140 that supplies driving power to the computer main body 100, and outputs from the input/output board 110. A central processing unit (CPU) 120 that determines a computer's use or non-use state based on an input signal or a signal according to a switch operation, and controls the output of a digital interface signal according to the determined state of the computer, A VGA board 150 for generating a digital interface signal to the monitor 200 under the control of the central processing unit 120, and a memory 130 connected to the central processing unit 120.

Here, it is preferable that the computer main body 100 differentially generate the digital interface signal according to a power-on state, a power-off state, and a power-saving state.

In addition, the digital interface signal uses a VGA signal transmitted from the computer main body 100 to the monitor 200, and when the power is on, the VGA signal is generated as a high signal (5V), and the power off state Alternatively, in the power saving state, the VGA signal is generated as a low signal (0V).

The monitor 200 serves to cut off or supply power by using a digital interface signal generated from the computer main body 100 as a power control signal.

Such a monitor 200 is a video connector 220 for interfacing a digital interface signal (DVI; Digital Visual Interface) output from the computer body 100, switching according to the digital interface signal received from the video connector 220 DC voltage cut-off unit 230 for controlling power by blocking or supplying monitor operation power (DC12V) output from the mode power supply (SMPS) 210, and monitor operation power supplied by the DC voltage cut-off unit 230 It includes a monitor control board 240 for controlling the entire operation of the monitor by driving. Here, when the computer main body 100 and the video connector 220 are connected through a High-Definition Multimedia Interface (HDMI) method, the digital interface signal is replaced with an HDMI signal.

As shown in FIG. 2, the DC voltage blocking unit 230 includes a switching element Q1 that performs a switching operation according to a digital interface signal (DVI signal) output from the video connector 220; And a MOSFET 231 interlocking with the switching element Q1 to cut off or supply the monitor operation power.

The switching element Q1 uses a field effect transistor (FET), the digital interface signal is connected to the base of the field effect transistor Q1, and the gate of the MOSFET 231 is connected to the collector of the field effect transistor. The monitor operation power is connected to the source of the MOSFET 231 and the output terminal of the monitor operation power is connected to the drain of the MOSFET 231.

Thus, when power is normally supplied to the computer main body 100, and as a result of checking the input signal of the input device 10, the central processing unit 120 controls the VGA board 150 and is in a use mode other than the power saving mode. The digital interface signal (DVI5V) is generated normally (high signal). Here, the VGA board 150 generally transmits a digital interface signal to the monitor 200 using pin 9. The digital interface signal generated in this way is transmitted to the monitor 200 and transmitted to the DC voltage cut-off unit 230 through the video connector 220 of the monitor 200. Here, the video connector 220 transmits the input digital interface signal to the DC voltage blocking unit 230 using pin 14.

As shown in FIG. 3, the DC voltage cut-off unit 230 has a high potential base of the switching element Q1 by the high-level digital interface signal, so that the switch element Q1 is turned on. When the switching element Q1 is turned on, the potential of the gate of the P-type MOSFET 231 connected to the collector is lowered to turn on the MOSFET 231. When the MOSFET 231 is turned on, the monitor operation power (DC12V) output from the switching mode power supply 210 connected to the source of the MOSFET 231 flows to the drain and supplies the monitor operation power to the monitor control board 24. do. Accordingly, the monitor 200 operates normally and displays the corresponding data on the screen.

That is, when the computer main body 100 is operating normally, a VGA signal is normally generated and transmitted to the monitor 200, and the monitor 200 uses the transmitted normal VGA signal to operate the monitor generated by the switching mode power supply. Supply power to the monitor control board normally, so that the monitor operates normally.

On the contrary, when the power to the computer main body 100 is turned off or the input device 10 is in a power saving mode and is not in use as a result of checking the input signal of the input device 10, the central processing unit 120 cannot control the VGA board 150 normally. , The VGA board 150 cannot normally (high signal) the digital interface signal (DVI5V). That is, a low signal (0V) is generated electrically. Here, the VGA board 150 generally transmits a digital interface signal to the monitor 200 using pin 9. The resulting low-level digital interface signal is transmitted to the monitor 200 and transmitted to the DC voltage blocking unit 230 through the video connector 220 of the monitor 200. Here, the video connector 220 transmits the input low-level digital interface signal to the DC voltage blocking unit 230 using pin 14. When the digital interface method is an HDMI interface method, the video connector 220 outputs a digital interface signal using pin 18.

As shown in FIG. 2, the DC voltage cut-off unit 230 causes the base of the switching element Q1 to be in a low potential state by the low-level digital interface signal, and the switch element Q1 is turned off. When the switching element Q1 is turned off, a potential of the gate of the P-type MOSFET 231 connected to the collector increases, thereby turning off the MOSFET 231. When the MOSFET 231 is turned off, the monitor operation power (DC12V) output from the switching mode power supply 210 connected to the source of the MOSFET 231 does not flow to the drain, so that the monitor operation power is transferred to the monitor control board 24. Cut off the supply. As a result, the monitor 200 is turned off.

In this case, conventionally, only the monitor screen has been turned off, but the second prior art essentially cuts off power (monitor operation power) supplied to the monitor control board, thereby preventing power waste.

That is, when the computer main body 100 is not in use, a VGA signal is not generated, so a low-level digital interface signal is transmitted to the monitor 200, and the monitor 200 is in a switching mode using the transmitted low-level VGA signal. The monitor operation power generated by the power supply is blocked from being supplied to the monitor control board.

On the other hand, when the computer main body 100 returns to the normal state in a state in which the power, which is the monitor driving power, is turned off by itself as described above, the VGA board 150 is controlled by the control of the central processing unit 120 A high-level digital interface signal is generated and transmitted to the monitor 200. In addition, the monitor 200 supplies the monitor driving power (DC12V) generated by the switching mode power supply 210 to the monitor control board 240 again using the transmitted high-level digital interface signal to the monitor 200. Is operated again in a normal state.

As described above, the second conventional technology automatically supplies the power of the monitor (monitor operation power) using the VGA signal (digital interface signal) generated from the computer main body 100 to the monitor 200 without user manipulation. Or by blocking, it provides very convenience to the user. In particular, it is possible to control the standby power of the monitor by using only the VGA signal between the main body of the computer and the monitor without configuring a separate control device for power control of the monitor, thus minimizing the cost of implementing the device for power cutoff. It will be possible.

However, the second prior art also requires power consumption for the detection operation of the monitor in order to check the power state of the PC. Specifically, the power mode is largely'Power ON mode','Power saving mode (DPMS)', ' There is a'power off mode', and in the power saving mode, about 1.4W is generally consumed for the operation of the DC voltage cut-off unit 230 for detecting and checking this.

The screen is turned off, but only the inverter power is turned off for a state that can be turned on immediately, and power is supplied to an operation circuit such as the DC voltage cut-off unit 230.

Existing monitors such as CRTs require this technology because the screen appears longer, but the power-saving mode is hardly necessary because the monitor is activated immediately when the power is turned on for recent monitors, but nonetheless, there is still a factor that wastes more energy. Has become.

In order to solve the problems of the second prior art, the present inventors cut off the power to the converter as well as the control unit itself in a very simple and simple manner when a sleep mode entry event comes from the PC. A third prior art has been proposed in which only the minimum power supply for operating only the firmware of the control unit is supplied, so that there is little difference between the off mode and the power consumption, which is called "control device and method of a maximum power saving monitor in sleep mode" As a result, a patent application (Application No. 2016-168870) and a patent have been made (Patent No. 1744927).

The third prior art will be described with reference to FIGS. 4 to 7.

First, an apparatus and method for controlling a maximum power saving monitor in a sleep mode according to the third prior art will be described with reference to FIGS. 4 to 7.

4 is a block diagram of an apparatus for controlling a maximum power saving type monitor and a peripheral device in a sleep mode according to the third prior art, and FIG. 5 is a process of entering a sleep mode among the control methods of the power saving monitor according to the third prior art. 6 is an operation flow diagram of a process of returning from the sleep mode in the control method of the power saving monitor according to the third prior art, and FIG. 7 is a prior art and maximum power saving in which the maximum power saving technology in the sleep mode is not applied. This is a test report showing the difference in power consumption of the monitor according to the third prior art to which the technology is applied.

As shown in FIG. 4, the control device of the power saving monitor in the third conventional technology includes an SMPS 20 that supplies power to the monitor, an LED panel 80 that operates as a backlight of the monitor screen, and the SMPS. Inverter 70 for inverting the voltage from the LED panel 80 and supplying it to the LED panel 80, a monitor control unit 30 for controlling the operation of the monitor, a connector 40 for providing a monitor signal from the main board to the monitor control unit, and Including a key control unit 90 consisting of buttons for setting the operation of the monitor, the monitor control unit 30, the inverter 70 by emitting a'Low' signal to the'PIO_INV' in the sleep (Sleep) mode, When the power of inverters such as the audio amplifier 71 and the USB hub 72 are turned off, and a wake-up signal is not input within a certain time, a trigger signal for a certain period of time (for example,'PIO_PWR') 50ms' pulse wave) is generated and inverted for a short period of time as long as the time the power switch (POWER SW) of the KEY CONTROL 90 is pressed, and all but the firmware 38 are deactivated. Mode.

Therefore, in the sleep mode, the monitor controller (Scaler IC) 30 can receive an input signal with a minimum power of about 0.3W that operates only the firmware, and only when a wake up event comes in,'PIO_INV' The monitor power is turned on by generating a signal of'High' and a turn-on signal to'PIO_PWR'.

That is, the trigger signal for transitioning to the sleep mode is a state in which only firmware capable of checking the wake-up state from the main mode is activated, and the user powers the key control unit 90 to deactivate the rest of the monitor control unit. It becomes the same signal as the signal for pressing the off button (for example, an off signal of about 50ms).

Preferably, the first switching element 51 and the second switching element 52 are posted between the SMPS 20 and the inverter 70, and the'Low' signal of the'PIO_INV' in the sleep mode It is deactivated by and cuts off power and control signals to the inverter or the like. For example, the first switching element 51 is a switching element that cuts off a 12V or 19V operating power from the SMPS 20 to the inverter 70, and the second switching element 52 is the SMPS 20 It is a switching element that blocks an inverter on/off control signal and/or an inverter dimming control signal (ON/OFF/DIM) from the inverter 70 to the inverter 70.

Preferably, the switching unit 60 is connected to the input terminal of the power switch (POWER SW) of the key control unit 90, activated and automatically turned off by the trigger signal of the'PIO_PWR' in the sleep mode. As a result, a kind of pulse wave for triggering is provided, and a turn-off signal of the monitor control unit is applied to the input terminal of the power switch (POWER SW) of the key control unit 90.

Subsequently, the detailed circuit of the monitor control unit 30 will be described in detail with reference to FIG. 4.

First, the MCU 31 is a main body that performs the operation of the entire control unit, interfacing with the firmware 38, the flash memory 39, and the key control unit 90, while actually performing the sleep mode in the third prior art. It performs the control operation of the maximum power-saving monitor in.

Next, the dual interface engine 34 interfaces with connectors 40 such as an analog RGB connector 41, a DVI connector 42, and an HDMI connector 43, and the LVDS panel interface 35 is an inverter 70 And while interfacing with the LED panel 80, the control is performed, and the display processing engine 32 provides an inverter on/off control signal and an inverter dimming control signal to the SMPS 20, and the first and second A power and control signal blocking signal is emitted to the switching elements 51 and 52 through the'PIO_INV' terminal. Reference numeral '33' is an OSD, '36' is a power management, and '37' is a clock generator.

At this time, the upper power terminal of the switching unit 60 is directly connected to the VGA_5V of the connector 40 such as the analog RGB connector 41 and/or the DVI connector 42, and the lower power supply terminal is the key control unit 90 ) Is connected to the'POWER_SW' terminal, and the control terminal is connected to the'PIO_PWR' terminal of the firmware 38.

For reference, the PIO (Power Input/Output) control signals'PIO_INV' and'PIO_PWR' are controlled by a program of the firmware 38.

On the other hand, the VGA_5V of the connector 40 is directly connected to the power terminal (VDD) of the firmware 38 at the same time, so when the VGA_5V power is supplied from the main board of the computer, the firmware is activated, and in response, the power of the key control unit The switch is triggered, and soon the entire monitor control unit 30 is activated.

Now, the operation of the monitor control unit will be described in more detail with reference to FIGS. 5 and 6.

First, the third conventional method of controlling the maximum power saving monitor in the sleep mode is to turn off the inverter power through a'Low' signal to'PIO_INV' in the sleep mode, wait for a while, and then within a specific time. When the wake-up signal is not input, a trigger signal (e.g., a'H' pulse signal for 50 ms) is generated in the'PIO_PWR' and the time is short enough to power off the power switch (POWER SW) of the key control unit 90. During inversion, eventually all power except the firmware of the monitor control unit is turned off, almost all power of the monitor control unit is turned off, and the SMPS and the monitor control unit (Scaler IC) are effectively maintained at the minimum power (about 0.3W). It is turned off, and now when a wake-up event comes from the main board, the monitor power is turned on by generating a turn-on signal for the'PIO_INV' signal to'H' and the'PIO_PWR'.

Explaining this for each step, first, when the monitor power is'on' (S51), the monitor control unit 30 of the third prior art detects the state of the monitor and the PC power (S52), which is various as described above. This is done through a connector and a dual interface engine 34.

Thereafter, it is checked whether the sleep mode event has occurred (S53). If the sleep mode event has not occurred, it is checked continuously. If it does, the inverter 70, the audio amplifier 71 and the USB are set as PIO_INV ='L'. Power such as an inverter such as the hub 72 is turned off (S54).

After that, wait for a certain period of time (S55), check whether a wake-up has occurred (S56), and if a wake-up occurs, turn on the monitor power and start again from the beginning, otherwise (if the wake-up does not occur for a certain period of time) , By generating a trigger signal for a certain period of time (for example, a'H' pulse signal for 50 ms) in'PIO_PWR' (S57), it transitions to sleep mode in which all resources except the firmware 38 of the monitor control unit are deactivated. This is the same as the signal that the user presses the power off button in the key control unit 90 to deactivate the entire monitor control unit.

Thereafter, it checks whether a wakeup has occurred again (S58), and if a wakeup occurs, the monitor power is turned on and restarts from the beginning, otherwise (if the wakeup does not occur for a certain period of time), all processes are terminated ( S59).

For reference, even if the power is turned off, unless the monitor power plug is unplugged, the power is still connected to the SMPS to supply power to the monitor, so it consumes about 0.3W of power. It is different from the state in which the power plug of the monitor is finally unplugged, but this amount of power consumption is almost negligible.

On the other hand, in the sleep mode state in which almost all of the monitor power is turned off, the flow when a wake-up event occurs will be described with reference to FIG. 6.

In the case of the third prior art, even in a sleep mode in which almost all monitor power is turned off, the firmware checks whether a wake-up event has occurred (S61). When a wake-up event occurs from the main board of the computer, the Since the VGA_5V of the connector 40 is activated, a 5V operation power is applied to the upper power terminal of the switching unit 60, and an operation power VDD is also applied to the firmware 38 at the same time, so that the firmware is programmed. As it is, the'H' pulse of about 50 ms, for example, is applied to the'POWER_SW' terminal of the key control unit 90 through the PIO_PWR terminal (S62).

Eventually, the same effect as the power switch of the monitor is turned on, and the monitor control unit 30 is activated, the process proceeds to step S51 of FIG. 5, so that normal monitor control is performed (FIGS. 5 and 6). Refer to'A' in)

Therefore, in the case of the conventional monitor control unit, as shown in Fig. 7 (a), the power consumption of 1.4W was consumed even in the sleep mode, but the control device for the maximum power saving type monitor in the sleep mode of the third prior art and According to the method, as shown in (b) of FIG. 7, in the sleep mode, the power consumption of the conventional monitor is reduced from about 1.4W to 0.3W, and about 1.1W per PC can be saved. .

That is, according to the third prior art, when the computer enters the sleep mode, a sleep mode capable of reducing power consumption as much as possible by using the off function of all functions except for the firmware, and a control method of a maximum power saving monitor in an idle state. Will be able to provide.

However, even according to the third prior art, it is possible to save power only when a sleep mode is notified from the main board to the last, and the user is temporarily immersed in other tasks while using the computer (e.g., computer work In a state where the user hardly uses a computer, but is not in sleep mode (hereinafter referred to as'idle state'), the user is still in the third prior art. Since the monitor performs a full operation, there is an unnecessary energy consumption.

****

Furthermore, in order to solve the problems of the third prior art, the present inventors, in a very simple and simple manner, are recognized as sleep mode not only when a sleep mode entry event comes from the PC, but also the monitor itself, but are not in the sleep mode. Even in the idle state, the power to the converter as well as the control unit itself is cut off, supplying only the minimum power to operate only the firmware of the monitor control unit, so that there is little difference between the off mode and power consumption. A technology has been proposed, and it has been patented as Korean Patent No. 1953209 under the name of "Control Method of Hibernation Monitor in Sleep Mode and Idle State".

Hereinafter, the fourth prior art will be described with reference to FIGS. 8 to 12.

First, an apparatus for controlling a maximum power saving type monitor in a sleep mode and an idle state according to an embodiment of the fourth prior art will be described with reference to FIG. 8, which is almost similar to the device of the third prior art in FIG. 4. .

However, unlike the third prior art of FIG. 4, even if the monitor control unit 30 is not in the sleep mode, when it is determined that the monitor is in the idle state by self-inspection,'Low' is also displayed in'PIO_INV'. By emitting a'signal, the power of inverters such as the inverter 70, the audio amplifier 71, and the USB hub 72 is turned off, thereby further saving energy.

Therefore, in the sleep mode and in the idle state, the monitor controller (Scaler IC) 30 can receive an input signal with a minimum power of about 0.3W that operates only the firmware, and only when a wake up event comes in ' The monitor power is turned on by generating a turn-on signal in the PIO_INV' signal to'High' and the'PIO_PWR' signal.

That is, the trigger signal for performing the hibernation operation is a state in which only firmware capable of checking the wake-up state from the main mode is activated, and the user in the key control unit 90 deactivating the entire monitor control unit It becomes the same signal as the signal pressing the power-off button (for example, an off signal of about 50ms).

Preferably, the first switching element 51 and the second switching element 52 are posted between the SMPS 20 and the inverter 70, and the'PIO_INV' of the'PIO_INV' in a sleep mode and an idle state It is deactivated by the'Low' signal and cuts off the power and control signals to the inverter. As an example, the first switching element 51 is a switching element that cuts off the operating power of 19V as an example from the SMPS 20 to the inverter 70, and the second switching element 52 is the SMPS 20 It is a switching element that blocks an inverter on/off control signal and/or an inverter dimming control signal (ON/OFF/DIM) from the inverter 70 to the inverter 70.

Preferably, the switching unit 60 is connected to the input terminal of the power switch (POWER SW) of the key control unit 90, activated and automatically turned off by the trigger signal of the'PIO_PWR' in the sleep mode. As a result, a kind of pulse wave for triggering is provided, and a turn-off signal of the monitor control unit is applied to the input terminal of the power switch (POWER SW) of the key control unit 90.

Subsequently, the operation of the monitor control unit will be described with reference to FIGS. 9 and 10.

First, the control method of the hibernation monitor in sleep mode and idle state is to turn off the inverter power through a'Low' signal to'PIO_INV' in sleep mode and idle state, and wait for a while and then within a specific time. When the wake-up signal is not input, a trigger signal (e.g., a'H' pulse signal for 50 ms) is generated in the'PIO_PWR' and the time is short enough to power off the power switch (POWER SW) of the key control unit 90. During inversion, eventually all power except the firmware of the monitor control unit is turned off, almost all power of the monitor control unit is turned off, and the SMPS and the monitor control unit (Scaler IC) are effectively maintained at the minimum power (about 0.3W). It is turned off, and now when a wake-up event comes from the main board, the monitor power is turned on by generating a turn-on signal for the'PIO_INV' signal to'H' and the'PIO_PWR'.

Explaining this step by step, first, by the user, ① when the monitor power is turned on by clicking the key control unit 90 (S11), ② the monitor control unit 30 detects the status of the monitor and PC power. The bar S12, as described above, is achieved through various connectors and dual interface engines 34.

Thereafter, it checks whether the sleep mode event has occurred (S13), ③ If the sleep mode event has not occurred, it branches to the monitor screen search sub-process (S21 to S29) of Fig. 10, and ④ PIO_INV if the sleep mode event has occurred. ='L' to turn off the 19V power source such as the inverter 70, the audio amplifier 71 and the inverter such as the USB hub 72 (S14).

After that, ⑤ wait for a certain period of time (S15), check whether a wakeup occurs (S16), and ⑥ if wakeup does not occur (if wakeup does not occur for a certain period of time), a trigger signal for a certain period of time in'PIO_PWR' (For example, a'H' pulse signal for 50 ms) is generated (S17), and transitions to the software off mode in which all resources except the firmware 38 of the monitor control unit are deactivated, which is the key to deactivate the entire monitor control unit. It is almost the same as the signal that the user presses the power off button in the control unit 90. However, in the software off state, it is desirable to check the wake-up from the main board while consuming only a minimum amount of power, unlike the hardware off step in which the user actually turns off the power by pressing the power button.

⑦ On the other hand, as a result of the determination in the wakeup check step (S16), if the wakeup has occurred, PIO_INV ='H' and inverters such as the inverter 70, the audio amplifier 71, and the USB hub 72 The 19V power source, such as the lamp, is turned on, and it starts again from step S12 (S19).

For reference, even if the power is turned off, unless the monitor power plug is unplugged, the power is still connected to the SMPS to supply power to the monitor, so it consumes about 0.3W of power. It is different from the state in which the power plug of the monitor is finally unplugged, but this amount of power consumption is almost negligible.

On the other hand, as a result of the determination in the sleep mode event occurrence check step (S13), ③ if the sleep mode event does not occur, the branch goes to the monitor screen search subprocess (S21 to S29). do.

First, the MCU 31 of the monitor control unit initializes the repetition count check parameter N while making a monitor screen search request (S21). For reference, the reason for using the number of repetition check parameter (N) is that even if it is determined that it is temporarily idle, if the user temporarily recognizes it as an idle state between the boards for another task or a moment, and shifts to the deep sleep mode, the dip It is rather absurd because the switch between the sleep mode and the normal operation mode is too frequent, and there is no change in the monitor for a while in an unexpected state, but it is caused by an unintended transition to the deep sleep mode in case the user is using the system. This is to improve certainty by solving possible problems. That is, even if it is tentatively concluded that it is a non-operation state by checking various operation/non-operation patterns, it is to shift to the deep sleep mode only when it is repeated No times or more. The No is preferably about 10 to 100, more preferably about 20 to 60, and most preferably about 50, but is not necessarily limited thereto. Even if'No=50', it is only tens of seconds, so it is not a big sacrifice from the point of view of energy saving.

Thereafter, the input frame is captured by taking a snapshot, and the changed screen block is also captured by taking a snapshot (10 times as an example) (S22).

Thus, it is checked whether the change in the input is less than x% (for example, 5%) (S23), and if the change in the input is more than x%, the user is using the computer normally. If the change of is less than x%, there is little change in the screen, but to determine whether the user is in a special use situation such as a document writing status, or simply in a status such as a flash advertisement (idle status), an analysis of the screen change pattern below S24 is performed. Will run.

For reference, when the screen changes, the changed screen is captured a certain number of times (for example, 10 times), and then the change is checked, and the monitor recognizes the change of each pixel. In addition, since the sync (H_sync, V_sync) comes up when each screen starts, location information can also be grasped.

In addition, some typical patterns for input changes are previously databaseized, and these are stored in the database as'DB1','DB2','DB3','DB4', ...'DBn'.

For example,'DB1' is a database that stores a typical change pattern when the screen change amount of the captured image is more than 5% and there is no identical screen. If the screen change corresponds to'DB1', the current screen is a moving image. Is recognized as running.

Similarly,'DB2' is a database that stores a typical change pattern in the case where the image change is repetitive (for example, when the image changes 5 times and the same image is repeatedly progressed after a few seconds of pause), and the screen change is' In the case of'DB2', it is recognized that the current screen is executing a flash advertisement.

Continuing,'DB3' is a database that stores a typical change pattern when the image changes in the horizontal direction, and when the screen change corresponds to'DB3', the current screen is recognized as being in SNS chat or document creation. do.

In addition,'DB4' is a database in which a typical change pattern is stored when a small block repeatedly changes at a specific location of an image, and when the screen change corresponds to'DB4', the current screen is displayed as a clock or pop-up advertisement. Is recognized as displaying.

In this way, the typical screen change pattern from'DB1' to'DBn' is made into a database, and by contrasting with it, it is possible to quickly and easily grasp exactly what state the current monitor screen is changing with little resources.

Now, as a result of the determination in step S23, if the input change is less than x%, the database file'Screen Change Pattern.DBF' is called from the'DB1' to'DBn' so that the analysis of the screen change pattern can be started. Do (S24).

First, is the current screen change a'DB1' pattern screen? Whether or not it is judged (S25), if the currently captured screen change is a screen of the'DB1' pattern, since the video is currently being executed, it returns to step S22 (provisionally concluded that it is not in the idle state), and the current If the captured screen change is not the screen of the'DB1' pattern, the current video is not currently being executed. Therefore, from the viewpoint of running the video, it is tentatively concluded that the video is in an idle state, and the next step is taken for counting.

Next, as a result of the determination in step S25, if the currently captured screen change is not the screen of the'DB1' pattern, since the current video is not being executed, it moves to the next check step, and the current screen change is the screen of the'DB2' pattern. is it? Whether or not it is determined (S26), if the currently captured screen change is a screen of the'DB2' pattern, since the flash advertisement is currently being displayed, the next check step S27 is proceeded (provisionally concluded that it is not in an operating state). If the currently captured screen change is a screen of the'DB2' pattern, it is temporarily concluded that the current flash advertisement display is in a tentative state of operation, and the process returns to step S22.

Subsequently, as a result of the determination in step S26, if the currently captured screen change is a screen of the'DB2' pattern, it is highly likely to be a current flash advertisement, so the next check step is performed, and the current screen change is the'DB3' pattern. Is it a screen? It is determined whether or not (S27), if the currently captured screen change is a screen of the'DB3' pattern, it is currently being typed for chatting or document writing, so it returns to step S22 (provisionally concluded that it is not an idle state). If the currently captured screen change is not the screen of the'DB3' pattern, it is not currently being typed for chat or document writing, so from the point of view of the typing operation, it is tentatively concluded that it is in an idle state. Move on to the next step.

Subsequently, as a result of the determination in step S27, if the currently captured screen change is not the screen of the'DB3' pattern, at least the current typing operation is not performed, so the next check step is performed, and the current screen change is the'DB4' pattern. Is it the screen of? Whether or not it is judged (S28), if the currently captured screen change is a'DB4' pattern screen, the current display operation is a clock display or pop-up advertisement that is irrelevant to the user's intention, so the next step (S29) (Temporarily concluded that it is not in an operating state), and if the currently captured screen change is a screen of the'DB4' pattern, it is temporarily concluded that it is in an operating state temporarily from the viewpoint of the current pop-up advertisement display, and the process returns to step S22. do.

Now, as a result of the determination in step S28, if the currently captured screen change is a screen of the'DB4' pattern, it is determined that it is in an idle state by checking the'DB1' to'DB4' patterns. The inverter power supply may be turned off (the monitor power supply is switched to the deep sleep mode), but for more certainty, the repetition number parameter'N' is incremented (S29), and the repetition number parameter'N' is the reference value. (No) It is checked whether it is exceeded (S30).

Thus, as a result of the determination in step S30, if the repetition number parameter'N' is less than or equal to the reference value (No), the process returns to step S22 again, and when the repetition number parameter'N' exceeds the reference value (No), the next step When the current screen change is over y% (e.g. 5%), it is finally checked again, and if the current screen change is over y% (e.g. 5%), the idle state determination sub-process starts. It returns to step (S21) and checks again from the beginning. If the current screen change is still less than y% (for example, 5%), the sub-process is finally terminated, and the process proceeds to step S14 of FIG. 9. That is, PIO_INV ='L' to turn off the 19V power supply of inverters such as the inverter 70, the audio amplifier 71, and the USB hub 72 (S14), and then to the main routine of steps S14 to S19. Will proceed.

Now, for another example of the sub-process corresponding to FIG. 10, referring to FIGS. 8 and 9 with auxiliary reference, and mainly referring to FIG. 11, only steps S45 to S48, steps S25 to S28 of the first embodiment. Since it is different from the steps, descriptions of the remaining steps are omitted for simplicity.

After the'screen change pattern.DBF' is called in step S24 of FIG. 11 and analysis of the screen change pattern is started, does the pixel information of the current screen continue to change? It is determined whether or not (S45), if the pixel information of the current screen continues to change, since the current video or game is being executed, the process returns to step S22 (provisionally concluded that the current screen is not in an idle state). If the pixel information is not constantly changing, it is tentatively concluded that it is temporarily idle from the point of view of playing the video, and moves to the next step for counting.

Next, as a result of the determination in step S45, if the pixel information of the current screen is not continuously changing, since the video is not currently being executed, the next check step is performed, and does the pixel information of the current screen change in a constant vertical, horizontal, or horizontal direction? ? Whether or not it is determined (S46), if the pixel information of the current screen changes in a constant vertical, horizontal, or horizontal direction, since the document is currently being written, the process returns to step S22 (a tentative conclusion is made that it is not an idle state), If the pixel information on the current screen does not change in a constant direction, from the perspective of writing a document, it is tentatively concluded that it is in a tentatively idle state, and the next step is taken for counting.

Subsequently, as a result of the determination in step S46, if the pixel information on the current screen does not change in a constant direction, it is highly likely that the document is not currently being created, so the next check step is performed, and the color of the current screen is changed. Is less than z colors (for example, z=10)? Whether or not it is determined (S47), if the color change of the current screen is less than z colors (for example, z=10), there is a high possibility that the current user is reading an e-book, so the process proceeds to step S22. It returns (provisionally concludes that it is not in the idle state), and if the color change of the current screen is more than z colors (for example, z=10), it is tentatively concluded that it is temporarily idle in terms of e-book execution, Go to the next step for counting.

Subsequently, as a result of the determination in step S47, if the color change of the current screen is more than z colors (for example, z=10), at least the electronic book is not currently being executed, so it moves to the next check step and changes the current image. Is it repetitive at a specific location? It is determined whether or not (S48), if the change of the current image is repetitive at a specific position, the current display operation is not displaying a clock or pop-up advertisement irrelevant to the user's intention, and thus the next step (S29) is performed. (Temporarily concluded that the current image is not in an operating state), if the change in the current image is not repetitive at a specific position, it is temporarily concluded that the current pop-up advertisement display is in a tentative state, and the process returns to step S22.

Now, as a result of the determination in step S48, if the change of the current image is repetitive at a specific position, it is determined to be in an idle state by a series of checks in steps S45 to S48, so that the power of the inverter in step S14 is immediately turned off. (The monitor power is switched to the deep sleep mode), but for more certainty, the repetition number parameter'N' is also incremented (S29), and the repetition number parameter'N' exceeds the reference value (No). Whether or not it is checked (S30), and if the repetition number parameter'N' exceeds the reference value (No), the process proceeds to the next step. It is determined whether the current screen change is y% (for example, 5%) or more. If the current screen change is still less than y% (for example, 5%), the sub-process is finally terminated, and the process proceeds to step S14 of FIG. 9. That is, PIO_INV ='L' to turn off the 19V power supply of inverters such as the inverter 70, the audio amplifier 71, and the USB hub 72 (S14), and then to the main routine of steps S14 to S19. Will proceed.

Now, for another example of the sub-process corresponding to FIG. 10, referring to FIGS. 8 and 9 with auxiliary reference, and mainly referring to FIG. 12, only steps S55 to S58, steps S25 to S25 of the first embodiment Since step S28 (and step S45 to step S48 of the second embodiment) is different, the description of the remaining steps is omitted for simplicity.

After the'screen change pattern.DBF' is called in step S24 of FIG. 12 and analysis of the screen change pattern is started, does the sum of the horizontal/vertical values of the pixel color information of the current screen change block continue to change? Whether or not it is determined (S55), in such a case, since the video or game is currently being executed, the process returns to step S22 (provisionally concluded that the video is not in an idle state). From the point of view, it concludes that it is tentatively idle, and moves to the next step for counting.

Next, as a result of the determination in step S55, if the sum of the horizontal/vertical values of the pixel color information of the current screen change block does not continuously change, the current video is not currently being executed, and thus the next check step is performed. Is the change block reduced by one and the average change is more than w% (eg 3%)? It is determined whether or not (S56), in that case, since it is currently being typed, it returns to step S22 (a tentative conclusion is made that it is not idle), and if not, it is temporarily idle from the point of view of typing. It concludes a tentative conclusion that it is in a state, and proceeds to the next step for counting.

Subsequently, as a result of the determination in step S56, if the sum of the horizontal/vertical values of the pixel color information of the current screen change block does not continuously change, it is highly likely that the user is not currently typing. Is the pixel color information of the current screen changing block changing beyond a certain level? Whether or not it is determined (S57), if the pixel color information of the current screen change block does not change very much, it is highly likely that the current user is typing or reading an e-book, so the step S22 (Temporarily conclude that it is not idle), and if the pixel color information of the current screen change block is changing beyond a certain level, it is temporarily concluded that typing and e-book are not being executed, and counting is performed. To the next step.

Subsequently, as a result of the determination in step S57, if the pixel color information of the change block of the current screen is changing to a certain level or more, at least typing or e-book is not currently being executed, so the next check step proceeds to the current screen. Is the sum of the horizontal/vertical values of the pixel color information of the block of change in the matched pattern? Whether or not it is judged (S58), in that case, since the current display operation is in flash advertisement that is irrelevant to the user's intention, it proceeds to the next step (S29) (provisionally concluded that it is not in the operation state). If not, it is determined that the current flash advertisement is in a tentative state of operation, and the process returns to step S22.

Now, as a result of the determination in step S58, if the sum of the horizontal/vertical values of the pixel color information of the current screen change block matches the pattern, it is determined to be in the idle state by a series of checks in steps S55 to S58, Immediately, the inverter power in step S14 may be turned off (the monitor power is switched to the deep sleep mode), but for more certainty, the repetition number parameter'N' is also incremented (S29), and the number of repetitions is It is checked whether the parameter'N' exceeds the reference value (No) (S30), and if the repetition number parameter'N' exceeds the reference value (No), the process proceeds to the next step, and the current screen change is y%. It is checked once again whether it is more than (for example 5%), and if the current screen change is still less than y% (for example, 5%), the sub-process is finally terminated, and the process proceeds to step S14 of FIG. 9. That is, PIO_INV ='L' to turn off the 19V power supply of inverters such as the inverter 70, the audio amplifier 71, and the USB hub 72 (S14), and then to the main routine of steps S14 to S19. Will proceed.

In more detail with respect to the MCU 31 of the monitor control unit 30, the main control unit 31a turns on the second switching element 52 through a power control signal PWR_CTRL while being activated by a DDC signal from the main board. As an example, 3VSB standby power is applied to the 1.2V voltage regulator 50 so that the entire MCU 31 is activated, and an inverter control signal (INV_CTRL) is issued to the time controller 32', and the time controller 32' 19V operating power such as an inverter such as the inverter 70, the audio amplifier 71, and the USB hub 72 by turning on/off the first switching element 51 through the inverter ON/OFF control signal INV_ON from While turning on/off, the brightness of the monitor is controlled by the inverter dimming control signal PWM_CTRL from the time controller 32' at the same time.

That is, in the sleep mode, a'Low' control signal (INV_CTRL) is issued to the time controller 32' to turn off the first switching element 51 to turn off the inverter 70, the audio amplifier 71, and the USB hub ( 72) turns off the power of the inverter, etc., and furthermore, if the wake-up signal is not input within a specific time, a trigger signal for a certain period of time through the'SLEEP ON' control signal to the trigger switching unit 60 (example , A pulse wave of about 50 ms) is generated and inverted for a short time as long as the time the power switch (POWER SW) of the key control unit (90) is pressed, excluding only the main control unit (31a). A sleep mode in which all are deactivated is performed, and even if it is not in the sleep mode, when it is determined that it is in an idle state, the (maximum) power saving operation as described above is also performed.

Above all, the MCU 31 in the present invention analyzes the type of program currently being executed, assigns a dimming control level (brightness level) of each program in advance, and performs dimming control accordingly, thereby saving power even during program execution. However, this is simply performed by analyzing the matrix value of the app recognition mark or the headline block. Now, the configuration for analyzing the matrix value of the headline of the execution program in the present invention of the MCU 31 In detail, the app recognition mark of the program currently being executed in the app recognition mark/headline block extraction unit 31d by receiving the monitor data input from the input image analysis unit 31e (for example, the Excel program mark in FIG. ) And/or the headline block (for example, the left part of the Hangul program headline in FIG. 18), and analyzing and data decoding the app recognition mark and/or the headline block extracted from the calculation unit 31c to obtain a matrix value. After calculating, the app recognition mark/headline block matrix value comparison unit 31b compares it with the matrix value previously stored in the app recognition mark/headline block matrix value storage unit 39', and is currently executed. By simply grasping the kind of program there is, appropriate dimming control is performed according to the type of application program. That is, when the inverter control signal (INV_CTRL) is issued to the time controller 32', the time controller 32' calculates the on/off time interval for PWM control and transmits the PWM control signal (PWM_CTRL) to the panel interface 35. As a result, the power factor of the PWM signal to the inverter 70 is ultimately controlled, so that the monitor dimming control of the LED panel 80 can be properly and efficiently performed. The decoding into the matrix value will be described later with reference to FIG. 17.

) 를 말하며, '헤드라인블록'이란, 도 18에서 보는 바와 같이, 응용프로그램의 상단에 표시되는 독특한 고유의 리본 메뉴의 적어도 일부 (일례로 한글 프로그램의 경우의

)를 말한다.For reference, in this specification, the'app recognition mark' is displayed on the upper left of the application program (simply referred to as'App.'or'app'), as shown in Fig. 17(a). Unique recognition mark (for example, in the case of an Excel program,

), and the'headline block' means at least a portion of the unique unique ribbon menu displayed on the top of the application program (for example, in the case of a Korean program), as shown in FIG.

).

On the other hand, depending on the running application, there may be cases where there is no unique app recognition mark. Even in such a case, a unique ribbon menu is arranged according to each program being executed, and the head of the screen of the program being executed. Each line has its own pattern or value. In the end, if there is no unique app recognition mark, the headline block corresponding to the left part of the headline of the executed program screen is captured (see Fig. 18), and the program Make it easier to recognize the type of The recognition method in this case is also mostly the same as the method through the above-described app recognition mark identification through matrix value analysis, but only the headline block matrix value is replaced with the app recognition mark matrix value. In the end, since the app recognition mark also exists in the headline block, the former can be interpreted as a special case of the latter, and in the former case, the program type can be grasped by a simpler operation than the latter case. .

In addition, the MCU 31 in the present invention analyzes the screen change pattern of the currently executed program in the same manner as in the prior art, and the change pattern analysis unit 31f for determining whether to control the dimming step of the currently executed program. And it analyzes whether the current user is using the computer itself, so that it additionally has a computer usage analysis unit (31g) to enter the off state from the idle state, and which application program (app) in the firmware controls the dimming at which stage The screen change pattern DB and the headline block DB, which pre-defined whether it is a stage, are stored in advance.

That is, when it is difficult to analyze even with the app recognition mark matrix value and the headline block matrix value, supplementary power saving is performed by analyzing the general monitor usage pattern of the fourth prior art and whether a computer is used as shown in FIGS. 10 to 12. It is also possible to do it.

Therefore, unlike the third prior art of FIG. 4, the control device for a power-saving monitor according to an optimal embodiment of the present invention, even if the monitor control unit 30 is not in a sleep mode, is self-irradiated and the monitor is in an idle state. If it is determined that there is, it is possible to further save energy by turning off the power of inverters such as the inverter 70, the audio amplifier 71 and the USB hub 72 by emitting a'Low' signal to'INV_CTRL'. do. After all, in the sleep mode and the idle state, the monitor controller (Scaler IC) 30 can receive an input signal with the minimum power by operating only the main controller 31a among the MCU 31, and a wake up event. B. When VGA_5V is turned on, the power control signal (PWR_CTRL) and the inverter control signal (INV_CTRL) are issued, and the 19V monitor power is turned on with the'INV_ON' signal through the time controller 32' and the entire inverter control unit is controlled with the'PWR_CTRL' signal. Activate it. That is, the trigger signal for performing the hibernation operation is a state in which only the main control unit capable of checking the wake-up state from the main mode is activated, and the user in the key control unit 90 deactivating the rest of the monitor control unit. Becomes the same signal as the signal for pressing the power-off button (for example, an off signal of about 50ms).

More preferably, a first switching element 51 and a time controller 32 ′ are provided between the SMPS 20 and the inverter 70 to provide power to the inverter or the like in a sleep mode and an idle state. And while blocking the control signal, the PWM control signal (PWM_CTRL) is issued to the panel interface 35 according to the program being executed while the application program is being executed to perform PWM control of the inverter, thereby providing the brightness of the monitor suitable for the type of application program. Dimming control.

Reorganizing the various switching units, the first switching element 51 is a switching element that cuts off the operating power of 19V as an example from the SMPS 20 to the inverter 70, the second switching element 52 It is a switching element that cuts off the 1.2V standby power from the SMPS 20 to the MCU 31, and as described above, a trigger switching unit 60 is connected to the input terminal of the power switch (POWER SW) of the key control unit 90 , In the sleep mode, a kind of pulse wave for triggering is provided by being activated and automatically turned off by the'SLEEP_ON' trigger signal of the main control unit 31a. The power switch of the key control unit 90 (POWER SW) The monitor control unit turn-off signal is applied to the input terminal. At this time, the upper power terminal of the switching unit 60 is directly connected to VGA_5V of a connector such as the analog RGB connector and/or a DVI connector, and the lower power terminal is connected to the'POWER_SW' terminal of the key control unit 90. , The control terminal is connected to the'SLEEP_ON' terminal of the main controller 31a.

Meanwhile, the DDC of the connector is directly connected to the power supply terminal (VDD) of the main control unit 31a at the same time through the'DDC_ON_CTRL' signal line of the dual interface engine 34. Therefore, when the DDC power is supplied from the main board of the computer, the The main control unit 31a is activated, and in response to this, the power switch of the key control unit is triggered, and then, through the first switching element 52 and the voltage regulator 50, the entire MCU 31 and the entire monitor control unit 30 Is activated.

(Example of control method of power saving monitor)

Now, the operation of the monitor control unit will be described in more detail with reference to FIG. 13 and mainly with reference to FIGS. 14 to 18.

First, the control method of the energy-saving monitor device by analyzing the matrix value of the headline of the execution program of the present invention is, first, by the user, when the monitor power is'on' by clicking the key control unit 90 (S11 ), the monitor control unit 30 of the present invention detects the state of the monitor and PC power (S12), which is achieved through various connectors and dual interface engines 34 as described above.

After that, it checks whether the sleep mode event has occurred (S13). If the sleep mode event has not occurred, the monitor is in normal operation, so it branches to the monitor screen search sub-process (S21 to S29) in the next stage, and the sleep mode event occurs. If this occurs, by setting INV_CTRL ='L' and setting INV_ON_RATE ='L' from the time controller 32', the 19V power supply such as inverter 70, audio amplifier 71, and inverter such as USB hub 72 is turned on. While being turned off, the 3V standby power to the voltage regulator 50 is cut off by setting PWR_CTRL ='L' at the same time, so that the 1.2V standby power of the entire MCU 31 is cut off (S14).

Thereafter, it is checked whether a wakeup occurs within a certain time (S15), and if the wakeup occurs within a certain time, it returns for the first time, and if the wakeup does not occur for a certain time, it is checked whether VGA_5V ='H'. (S16).

Thus, if the wakeup does not occur for a certain period of time and VGA_5V ='L', a trigger signal for a certain period of time (for example, a'H' pulse signal for 50 ms) is generated at'SLEEP ON', and the MCU 31 of the monitor control unit is ), the software shifts to the software off mode in which all resources except the main control unit 31a are deactivated, which is almost the same as a signal that the user presses the power off button in the key control unit 90, which deactivates the entire monitor control unit. However, in the software off state, it is desirable to check the wake-up from the main board while consuming only a minimum amount of power, unlike the hardware off step in which the user actually turns off the power by pressing the power button.

On the other hand, if the determination result in the wakeup check step (S15), if a wakeup occurs, or even if the wakeup does not occur, if the determination result in the step S16 is'Y' (when a monitor signal comes in) , Similar to step S15, returning for the first time (to step S12), but activates INV_CTRL ='H' and PWR_CTRL ='H' so that power is applied to the entire MCU 31 while INV_ON_CTRL ='H ', the inverter 70, the audio amplifier 71, and the inverter such as the USB hub 72 turn on the 19V power, and it starts again from the step S12 (S19).

For reference, even if the power is turned off, unless the monitor power plug is unplugged, the power is still connected to the SMPS to supply power to the monitor, so it consumes about 0.3W of power. It is different from the state in which the power plug of the monitor is finally unplugged, but this amount of power consumption is almost negligible.

On the other hand, as a result of the determination in the sleep mode event occurrence check step (S13), if the sleep mode event does not occur, the process branches to the monitor screen search sub-processes (S21 to S29), which will be described in detail.

First, the main control unit 31a of the MCU 31 of the monitor control unit makes a monitor screen search request to the input image input unit 31e (S21).

Thereafter, the input image is received and analyzed by the input image input unit 31e, which is possible, for example, by analyzing monitor data from the main board (S22). At this time, the screen change pattern DB and the headline block DB are called from the firmware 38, and the app recognition mark/headline block matrix value is also called from the app recognition mark/headline block matrix value storage unit 39'.

Thereafter, it is checked whether the running app execution window is in the full window mode (S23), and if it is in the full window mode, the app recognition mark and/or the headline block are immediately extracted, and the corresponding portion of the monitor data is decoded to form a matrix ( S24).

As for the app recognition mark matrixing, as shown in FIG. 17, as an example, when it is assumed that the block size of the app recognition mark is "18 pixels * 25 pixels" in the horizontal direction in the A direction and the vertical in the B direction, it is in use. The general data throughput per second when checking whether or not is theoretically "horizontal number x color temperature number x RGB x vertical number x 60Hz = number of data processing per second", so "18 x 256 x 3 x 24 x 60 = 19,906,560 pieces" (See Fig. 17(a)) In the present invention, as shown in Fig. 17(b), in the block of the app recognition mark, the case where the RGB value of each pixel is more than a certain value is set to '1', and a certain value The following cases are given as '0' (you may decide by changing to a simple gray scale, or you may decide by assigning a weight to each color), and add the pixel values of each column along the A direction (horizontal direction). , Again, the value obtained by adding the pixel values of each row along the B direction (vertical direction) is made into one string as it is. For example, the matrix value of the app recognition mark for Excel becomes "01835610121066101086422000014310965646446566681021600".

That is, in the case of the application recognition mark matrixing according to the method of the present invention, as in (b) of FIG. 17, the matrix value is "(number of widths + number of lengths) x 60Hz", and "42 x 60 = 2,520 pcs." Invar, it is converted into dB and saved in advance, and the running'App Recognition Mark Check' is judged as the case where the number of the matrix values coincide. In particular, the analysis is completed after comparing only with the simple addition value '272' of each matrix value. If you do, in the end, you can save 8,228 times more resources with simple calculation.

Returning to FIG. 14 again, continuing the description of the control method of the energy-saving monitor device through the analysis of the matrix value of the headline of the execution program according to the present invention, the matrix value of the app recognition mark extracted in the same manner as described above. Which value of the app recognition mark matrix value DB previously stored in the app recognition mark matrix value storage unit 39' matches? Whether or not it is checked (S25).

Thus, as a result of the determination in step S25, if there is no, the process proceeds to the next step (S26), and if there is, it is determined which program is the currently executed application program (App.). S27) is performed, which will be described with reference to FIG. 15.

First, is the extracted app recognition mark corresponding to'document work'? Whether or not it is checked (S41). Thus, if the extracted app recognition mark is an app recognition mark corresponding to a'document work' such as Excel or Korean,'dimming control level 1'is given with the darkest monitor screen brightness (S42), and accordingly, the main control unit 31a transmits an inverter control signal INV_CTRL corresponding thereto to the time controller 32', and performs dimming control again through the inverter dimming control signal PWM_CTRL.

Then, in the program recognition subroutine (S27), is the extracted app recognition mark an app recognition mark corresponding to'Internet, e-book use'? Whether or not it is checked (S43). Thus, if the extracted app recognition mark is an app recognition mark corresponding to Internet or e-book use, a'dimming control level 2'having a brighter monitor screen brightness is given (S44), and accordingly, the main control unit 31a [0105] The next step of dimming control is performed through the inverter dimming control signal PWM_CTRL, which is output to the time controller 32' corresponding to the inverter control signal INV_CTRL.

Subsequently, in the program recognition subroutine (S27), is the extracted app recognition mark corresponding to the'movie or game mode' app recognition mark? Whether or not it is checked (S45). Thus, if the extracted app recognition mark is an app recognition mark corresponding to a movie or game mode,'dimming control level 3'with the brightest monitor screen brightness is given (S46), and accordingly, the main control unit 31a A corresponding inverter control signal INV_CTRL is issued to the controller 32', and the brightest dimming control is performed again through the inverter dimming control signal PWM_CTRL.

In some cases, in the program recognition subroutine (S27), is the extracted app recognition mark any other app recognition mark? Whether or not it is checked (S47), in such a case, a'dimming control level 4'is given (S48), and then the process returns to S30 of FIG. For this, it is desirable to allow the user to set an arbitrary level.

Meanwhile, as a result of the determination in step S25 of FIG. 14, the matrix value of the app recognition mark extracted in the manner described above is the app recognition mark matrix value previously stored in the app recognition mark matrix value storage unit 39'. If it does not match any of the DB values, the extracted app recognition mark is an unregistered app recognition mark or an application program that does not have an app recognition mark, so the extracted headline block is a matrix value storage unit 39' Which value of the headline block matrix value DB previously stored in is matched? Whether or not it is checked (S26). As an example, the headline block designates a block from (0, 0) pixels to (100, 100) pixels and decodes the monitor data in the corresponding block, and then in a similar manner as in FIG. 17(b). Make sure that the matrixed value is used.

Thus, as a result of the determination in step S26, it is determined which program is the currently executed application program (App.), and thus, the limited program recognition subroutine (S28) is performed on the identified headline block. , As in FIG. 15, is performed.

On the other hand, if there is no result of the determination in step S26, the process proceeds to the known program recognition subroutine (S29) as in the fourth prior art, and then proceeds to step S30, where it is determined whether or not a new app is executed. Bar, if a new app is running, it returns to step S21 and performs a new monitor screen search sub-process. On the other hand, if a new app is not running, to check whether it is in the idle state, the screen pattern is in an unused state. is it? Whether or not it is determined (S31).

Thus, as a result of the determination in step S31, if the state is not in use, steps S30 and S31 are repeatedly performed, and if the state is not in use, step S14 proceeds to the idle mode.

Now, finally, referring to FIG. 16, as a result of the determination in step S23 of the main process of FIG. 14, for matrixing when the running application program (App) is not in the full window mode, referring to FIG. , Explain.

As shown in Fig. 16, if the execution window of the currently running application program is not in full window mode while working with several windows open in the window, once a specific first window is selected (S51), app recognition Is the color temperature of the background next to the mark and/or headline block darker than the standard value, for example, by 10% or more? Whether or not it is checked (S52), the reason for such a check is that a background brighter than a standard value is a currently running'TOP Window'. That is, it is to check whether the first randomly selected window is the currently running'TOP Window'.

Thus, as a result of the determination in step S52, if not, since the currently selected first window is the currently running'TOP Window', the app recognition mark and/or headline block based on the currently selected first window After extracting and decoding the corresponding part of the monitor data (S54), after that, as shown in FIG. 17, the application recognition mark matrixing is performed.

On the other hand, as a result of the determination in step S52, in such a case, since the currently selected first window is not the currently running'TOP Window', the next window is selected and performed again from the step S52, and the currently running ' It repeats until it finds'TOP Window'.

As described above, according to the'energy-saving monitor device and its control method through the analysis of the matrix value of the running program's headline' of the present invention, i) the application of the currently running application program (App) primarily only with the app recognition mark matrix value. By simply grasping the type and performing monitor dimming control appropriate for it, monitor power consumption can be performed in a simple manner, and ii) The application currently being executed with the headline block matrix value even if the app recognition mark does not exist or is not registered. By simply grasping the type of program (App) and performing monitor dimming control appropriate thereto, monitor power consumption can also be performed in a simple manner, and iii) simple switching elements 51, 52, 60 in idle mode or in a state where a computer is not used. ), it is possible to cut off the power of the inverter by switching off the power of the inverter or cut off the standby power of all the monitor control units except the main control unit of the MCU to maximize the power consumption of the monitor.

In the above, the present invention has been described according to an embodiment of the present invention, but changes and modifications within the scope not departing from the spirit of the present invention by those of ordinary skill in the art belong to the present invention. Of course.
