Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified:
With reference to shown in Figure 1; A kind of low-power consumption standby that present embodiment discloses and the television circuit that wakes up; Comprise display screen, television drive chip 3, power circuit 4, remote control circuit 5, key control circuit 6, standby start control module MCU 7 and testing circuit 8, display screen comprises display panel control circuit 1 and backlight 2; Remote control circuit 5 comprises remote control circuit first signal output port; Key control circuit 6 comprises key control circuit first signal output port and key control circuit secondary signal output port; Television drive chip 3 comprises television drive chip first signal output port, television drive chip secondary signal output port, television drive chip first signal input port, television drive chip secondary signal input port, television drive chip the 3rd signal input port and television drive chip current input terminal mouth; Power circuit 4 comprises the first current output terminal mouth, the second current output terminal mouth and power circuit signal input port; Display panel control circuit 1 is provided with the display panel control circuit signal input port; Backlight 2 is provided with the backlight current input port; Standby start control module MCU 7 is provided with standby start control module MCU first signal input port, standby start control module MCU secondary signal input port, standby start control module MCU the 3rd signal input port, standby start control module MCU first signal output port and standby start control module MCU secondary signal output port; Testing circuit 8 is provided with testing circuit signal input port and testing circuit signal output port; Wherein, remote control circuit first signal output port is connected with standby start control module MCU the 3rd signal input port and television drive chip the 3rd signal input port signal; Key control circuit first signal output port is connected with the standby start control module MCU first signal input port signal, and key control circuit secondary signal output port is connected with the television drive chip first signal input port signal; Television drive chip secondary signal input port is connected with the standby start control module MCU first signal output port signal; Television drive chip first signal output port is connected with display panel control circuit signal input port signal; Television drive chip secondary signal output port is connected with testing circuit signal input port signal, and the first current output terminal mouth of television drive chip current input terminal mouth and power circuit electrically connects; Second current output terminal mouth of power circuit and said backlight current input port electrically connect; The power circuit signal input port is connected with standby start control module MCU secondary signal output port signal, and the testing circuit signal output port is connected with standby start control module MCU secondary signal input port signal.In addition, television drive chip is the MST6M16JS chip, and standby start control module MCU is the MC9RS08KA2 chip.
To shown in Figure 4, at first, the standby start control module MCU conversion of signals of importing is become the discernible level signal of MC9RS08KA2 chip with reference to Fig. 2.The circuit of Fig. 2 is input as the capable field sync signal of PC passage, VGA_CHECK pin output 5V and 0V voltage signal.When the row field synchronization all existed, the VGA_CHECK pin was 0V; When the row field synchronization had one tunnel no signal or two-way all not to have signal, the VGA_CHECK pin was 5V.The MC9RS08KA2 chip that this level signal directly inputs among Fig. 3 detects.
Secondly, through the MC9RS08KA2 chip large scale panel TV main board system power supply is controlled.As shown in Figure 3, CN1 is the input of television drive chip power supply, and 5Vstb is the holding state power supply ,+12V and+power supply when 5V_2 is system's operate as normal, STB be+12V and+5V_2 power supply control pin.When MC9RS08KA2 chip controls pin PTA3 output high level, STB is a high level, and+12V begins the power supply to system, television drive chip operate as normal with+5V_2 power supply; Otherwise ,+12V and+5V_2 dump, system's power supply stops to get into holding state.This shows that under the holding state, basic only the need gets final product for the MC9RS08KA2 chip power supply through 5Vstb.Therefore, realized design to system's super low-power consumption.
At last, the realization of television drive chip arousal function.When the MC9RS08KA2 chip detects the VGA_CHECK signal and is low level through the PTA0 pin; Think that television drive chip has the signal input; As this moment at the PC passage and at standby mode, will remove to control power supply through the STB signal that PTA3 exports high level, complete machine will get into normal operating conditions.
Simultaneously, the MC9RS08KA2 chip can be imported remote controller IR signal and keypad KEY_POWER signal, and system mode is controlled.Single-chip microcomputer is only discerned the POWER control signal of IR signal, and other controlled function are carried out by the MST6M16JS chip.The state of system when the data that the MC9RS08KA2 chip reads EEPROM 24C32 through iic bus SDA and SCL go to differentiate shutdown, waken system whether when signal being arranged with decision PC.Because when the holding state of non-PC passage, need not carry out the PC arousal function.This EEPROM and system are shared, can not increase system cost.
