Therefore, display terminal provided by the invention, the duty (outer computer exports off signal or standby signal) of the touching signals that can input according to outside and outer computer, automatically control to open or close main power source module, thus control whether open or close display terminal mainboard, when the touching signals received be standby signal or from the signal of outer computer be off signal and standby signal time, enter holding state, control to close and run display terminal mainboard, automatic stopping is to display terminal main board power supply, therefore, the present invention compared with prior art, very little stand-by power consumption can be realized, without the need to driving display terminal mainboard, display terminal mainboard quits work when standby, the present invention just expends a small amount of electric energy to drive touch switch module, whether touching signals is have input to detect user, when ensureing the normal working signal receiving user's input, display terminal mainboard can be opened in time, realize menu display function.The experiment proved that, the power consumption of display terminal of the present invention when standby can maintain below 4mw.Specify in view of according to International Electrotechnical Commission's IEC standard: the stand-by power consumption of display terminal regards as 0w at below 5mw, therefore, display terminal of the present invention is the display terminal of a stand-by power consumption 0 watt, the present invention effectively can save the power consumption of display terminal when standby, economize energy, thus the daily economy expenditure reducing user, the product use sense strengthening display terminal user is subject to, offer convenience to the work of user and life, be of great practical significance.
In the present invention, described display terminal can comprise the device that any one such as display, projector and all-in-one have menu display function.Described outer computer can comprise various types of computing machines such as existing desktop computer, notebook computer, palm PC and panel computer.
In the present invention, in specific implementation, described main power source module 101 can be a power IC IC on display terminal.
In the present invention, in specific implementation, described touch switch module 103 comprises electric capacity and refers to touch switch, conducting film pressure-sensitive switch and other various types of touch switches, in specific implementation, can be only a common touch switch logical circuit.
It should be noted that, as shown in Figure 2, in the present invention, described energising control module 104 includes relay T and stand-by circuit, wherein:
Described relay T, be connected with external power source, touch switch module, main power source module respectively, for when receiving normal power supply signal (as a high level signal) of touch switch module or the transmission of display terminal mainboard, energising is closed, external power source and display terminal mainboard are conducted, open and run main power source module, thus drive display terminal mainboard normally to work by main power source module; And when receiving the signal of stopping power supply of touch switch module or the transmission of display terminal mainboard, external power source and display terminal mainboard are disconnected, main power source module out of service, thus main power source module stops driving display terminal main board work;
Voltage conversion circuit, is connected with external power source, touch switch module respectively, for the voltage transitions that exported by external power source to the operating voltage of touch switch module, for touch switch module provides work electricity consumption.
In specific implementation, see Fig. 3, described energising control module 104 comprises a voltage conversion circuit and a relay T, and described touch switch module is a touch switch K.
Described in Fig. 3, the live wire input end e of described voltage conversion circuit meets fuse F1, F2 successively, node between described fuse F1 and F2 connects with the voltage input end g of relay T, and the voltage output end h of described relay T is connected with the live wire input end b of main power source module; Described fuse F2 meets the zero line input end a of external power source S (being specifically as follows 110V ~ 220V AC power of outside input) and described main power source module successively;
The zero line input end d of described voltage conversion circuit connects with the zero line input end a of described main power source module, and the voltage output end c of described main power source module is connected with the voltage input end of display terminal mainboard;
The voltage output end f of described voltage conversion circuit is connected with one end of touch switch K, and the other end of described touch switch K connects with the signal output part J of display terminal mainboard, the coil control end i of relay T respectively.
In the present invention, when display terminal is in holding state, if user wants normally to start display terminal, so user presses touch switch, after touch switch is pressed by user, the voltage that voltage conversion circuit exports will make the coil control end i conducting of relay T, and under electromagnetic action, make relay T close (namely voltage input end g is connected with voltage output end h), main power source module is started working.After main power source module work, display terminal mainboard energising work will export normal power supply signal (being such as the control signal of a high level) to the relay T in energising control module, relay T is made to continue to remain closed connection, even if at this moment touch switch K user no longer presses, relay T still keeps "on" position, thus main power source module still can normally work, display terminal is in normal operating conditions.
It should be noted that, when display terminal is in normal operating conditions, user does not press touch switch, voltage conversion circuit will not have load, voltage conversion circuit enters into standby mode, now main power source module normally works, and to display terminal main board power supply, whole display terminal normally carries out data display.
When user carries out power-off operation to the outer computer that display terminal connects, display terminal mainboard receives the off signal that outer computer exports, so transmission is stopped power supply signal to relay T by display terminal mainboard, relay T will disconnect, main power source module and external power source are disconnected power and quit work, thus display terminal mainboard loses power supply also quits work, simultaneously, because touch switch does not operate, voltage conversion circuit remains on standby mode.Now display terminal of the present invention enters holding state, and therefore, the present invention can when shutting down computer main frame, initiatively display terminal is closed without the need to user, can automatically enter into holding state pattern, eliminate the switch display terminal operation of user, improve the convenience that user uses.
It should be noted that, when display terminal is in stand-by operation state, just voltage conversion circuit remains on standby mode, main power source module and display terminal mainboard do not work, touch switch is also in because not having external pressing the state of flicking, and just there is voltage conversion circuit a small amount of power consumption in the standby state.
In the present invention, it should be noted that, for described main power source module, existing various types of display terminal power supply all can use.For main power source module, the zero line side that a end is external power source input, the live wire end that b end is external power source input; C end is voltage output end, for the operating voltage of output display terminal mainboard.A, b, c tri-ports are the voltage input and output side of main power source module, only work when normal work, when display terminal is standby, because relay T disconnects, therefore, described main power source module zero line input end b is without input, zero line input end a cannot form loop, then main power source module quits work, and voltage output end c stops output voltage, therefore main power source module not power consumption.Relay T, only after inline fuse F2, when main power source module short circuit, plays to main power source module the effect that disconnecting circuit protects.
In the present invention, for described voltage conversion circuit, d end is the zero line side of external power source input, and e end is the live wire end of external power source input, and f is the voltage output end of voltage conversion circuit.These three ports of d, e, f are the voltage input and output side of voltage conversion circuit, all work with during normal work standby.D end and e hold the input end for external power source, as long as there is input outside, these two ports at any time equal conducting form loop, then voltage conversion circuit is always in running order, f end keeps voltage to export, after touch switch K is pressed, f holds output voltage that relay T is closed, main power source module work after relay T is closed, then display terminal main board work, display terminal mainboard exports the normal power supply signal of high level to relay T, relay T is made to continue closed maintenance conducting, now the finger of user leaves touch switch K, relay T continues to keep conducting under the control of the normal power supply signal of display terminal mainboard.When user needs standby, can by the standby signal of display terminal mainboard output low level (such as 0V) or off signal to relay T, the closing end contact of relay T (i.e. voltage input end g and voltage output end h) is separated, main power source module is closed, and display terminal mainboard also quits work.
In the present invention, also it should be noted that, described external power source S can be 110V ~ 220V AC power of outside input, fuse F1 and F2 plays excess current safeguard protection effect, be specially: fuse F2 fuses when main power source module short circuit, such circuit disconnects, and prevents security incident; Fuse F1 fuses when the short circuit of standby power integrated circuit (IC), and such circuit disconnects, and prevents security incident.

It should be noted that, shown in Fig. 2, Fig. 3, for display terminal provided by the invention, when display terminal normally works, namely, when the touching signals that touch switch module receives is normal working signal, touch switch module sends normal power supply signal to energising control module, triggers startup optimization main power source module by energising control module, thus external power source and display terminal mainboard are conducted, for display terminal mainboard provides operating voltage.Be specially: after touch switch module is pressed, voltage conversion circuit output voltage in energising control module is to relay T, thus relay T closes, thus open operation main power source module, main power source module normally works and provides work electricity consumption to display terminal mainboard, export normal power supply signal to relay T after display terminal mainboard, guard relay is in closed on-state, thus display terminal still can normally work after touch switch is upspring.Therefore, display terminal complete machine can normally show, and is in normal operating conditions.
In addition, when user carries out performing power-off operation to outer computer, when at this moment needing display terminal to enter standby mode, outer computer exports off signal to display terminal mainboard, so display terminal mainboard can forward off signal to touch switch module, touch switch module is after receiving off signal, transmission be stopped power supply signal to relay T, relay T is disconnected, therefore main power source module out of service, thus external power source and display terminal mainboard are disconnected, display terminal mainboard is stopped power supply, no longer work, display terminal enters holding state.
After display terminal enters holding state, for the present invention, main power source module turns off, display terminal mainboard is stopped power supply and no longer works, only now that voltage conversion circuit needs to keep stand-by operation state, continue only for these parts of touch switch module provide work electricity consumption by voltage conversion circuit, therefore, display terminal of the present invention can change prior art when standby still to the mode of display terminal main board power supply, can thoroughly close display terminal mainboard, make voltage conversion circuit just for these parts of touch switch module provide work electricity consumption, do not start shooting when normally working and there is no load, extremely low power consumption can be realized.The experiment proved that, voltage conversion circuit only needs 4mW stand-by power consumption of having an appointment, specify according to International Electrotechnical Commission's IEC standard: the stand-by power consumption of display terminal regards as 0w at below 5mv, therefore, display terminal of the present invention can be described as the display terminal of a stand-by power consumption 0 watt, it effectively can save the power consumption of display terminal when standby, economize energy.
