Definitions

  • the present invention relates to an image display device that is automatically turned on when connected to the mains for the first time, instead of initiating stand-by state.
  • an image display device such as a TV set from the mains until the next time the image display device is to be powered.
  • the image display device When powered the next time, however, the image display device typically goes in stand-by mode and the user will need to take another step to activate the device, typically by way of pushing a respective turn-on button on the remote control or on the device’s front panel. Therefore, a noticeably extended period of time can be in question before all the components including the display panel of the image display device are activated, which may in turn cause discontent among users.
  • an image display device that is disconnected from the mains to save power instead of remaining in stand-by mode during inactive hours, should be conveniently and quickly turned on after being re-connected to the mains.
  • CN 101334644 discloses a power control turn-on/off circuit which takes a dual-coil dual-stable keeping relay as the kernel and comprises a turn-on micro-switch, a dual-coil dual-stable keeping relay, a booting coil driving circuit and a shutdown coil driving circuit.
  • the present invention provides a method for operating an image display device that can be quickly activated after being connected to the mains for the first time, as provided by the characterizing features defined in Claim 1.
  • Primary object of the present invention is to provide a method for operating an image display device according to which, a reduced activation time is imparted to the image display device.
  • the present invention proposes a method for operating an image display device, the latter having a power manager microcontroller, an electronic control unit and peripheral components such as the display panel and speakers.
  • the method for operating an image display device comprises the steps of a) connecting an image display device to an electrical power supply for the first time, that is after remaining disconnected therefrom for a certain time duration, b) maintaining power supply to the electronic control unit instead of cutting power to the same as is applicable in the case of stand-by mode, c) automatically performing the following sequence of actions without any such command from the user: loading the TV boot software, loading the TV operating software and loading the TV interface software, d) waiting for a corresponding control command from the user for preferably one minute to drive the display panel and speakers. Otherwise, i.e. if the intention of the user is not to turn on the TV, the image display device returns to stand-by mode.
  • Fig. 1 demonstrates a general flow diagram of the conventional sequence of actions performed when an image display device is connected to the power supply for the first time.
  • Fig. 2 demonstrates a general flow diagram of the sequence of actions performed when an image display device is connected to the power supply for the first time according to the present invention.
  • the present invention proposes a method for operating an image display device, the latter typically having a soft on/off switch, serving to the purpose of turning the device on and off.
  • a power manager microcontroller cuts power supply to respective components of the device, including the electronic control unit. This stand-by situation is maintained until a user attempts to energize the image display device using the same button associated with said soft on/off switch.
  • a soft on/off switch does therefore not directly interrupt power supply to the load.
  • a soft on/off switch is a momentary action switch that is released when the user removes his/her finger from the associated button.
  • the power manager microcontroller As the power manager microcontroller remains powered during stand-by mode, it still involves active power dissipation although no such indication is noticeable to the users. Due to the fact that zero stand-by power dissipation is only achievable if the power manager microcontroller remains disconnected from the power supply during stand-by mode, users generally tend to manually disconnect the image display device from the power supply until the next time the device will be used.
  • the image display device When a user connects the image display device to the power supply, the image display device typically goes in stand-by mode, i.e. power supply to the electronic control unit is cut and the user will need to take another step to activate the device, typically by way of pushing a respective turn-on button on the remote control or on the device’s front panel. Only then will the power manager microcontroller initiate activation of the image display device and the electronic control unit will be powered, which may accordingly take a noticeable time period which is by no means an immediate reaction and can therefore lead to discontent among users.
  • the device when the image display device is connected to the supply for the first time, i.e. after being disconnected for a certain period or the next day it is operated, the device enters in stand-by mode.
  • This situation originates from the fact that it might be the case that the device is disconnected from the mains due to a power failure, and that power is restored independently from the user so that actually no user action was taken to turn on the device.
  • the power manager microcontroller of the device waits for a respective signal from the user to initiate activation of the device and if the intention of the user is to turn on the image display device, he/she presses the respective turn-on button.
  • the device when the image display device is connected to the power for the first time, i.e. after being disconnected and reconnected, the device enters in a so-called command mode instead of stand-by mode.
  • the operational state of the device is maintained in command mode for a predetermined duration, during which all the routine actions for turning on the device are executed with the exception that the display panel and the speakers are not driven.
  • the visible operational state of the image display device at this stage is not different from the stand-by mode and the actual command mode is therefore not noticeable to the users.
  • the image display device therefore has two different operational modes. In the event that the device is energized for the first time, the device enters in command mode instead of stand-by mode and if a user presses the button associated with the soft on/off switch, a substantially reduced screen-on time is obtained as the electronic control unit already started activation procedure and the device can quickly respond to a screen-on command.
  • the present invention therefore proposes a method for operating an image display device according to which, when connected to the mains for the first time, the device automatically enters in a command mode instead of stand-by mode for a predetermined time duration.
  • the image display device When the image display device is powered for the first time, power supply to the electronic control unit is maintained and the following sequence of actions are automatically performed without waiting for user interaction: a) Loading of the boot software, b) Loading of the operating system and c) Loading of the TV interface software.
  • the power manager microcontroller waits for a respective signal from the user for a predetermined time duration to fulfill complete activation of the device.
  • peripheral components such as display panel and speakers are activated. Otherwise, that is, upon completion of the allotted time duration with no user interaction, power supply to the electronic control unit is cut and the device enters in stand-by mode.
  • the present invention proposes a method for operating an image display device, said image display device comprising a power manager microcontroller, an electronic control unit, a display panel and at least one speaker, said method for operating an image display device comprises the steps of:
  • the method for operating an image display device further comprises the step of driving said display panel and at least one speaker upon receipt of a corresponding control command from the user during said pre-specified time period.
  • the power manager microcontroller in the event that no interaction is sensed by the power manager microcontroller within the allotted time duration, i.e. if no user command is received, the power supply to the electronic control unit is cut and the image display device enters in stand-by mode.
  • the image display device can generate a sound indication upon termination of the allotted time duration, such sound indication serving to the purpose of providing a second time duration to the users before returning to the stand-by mode, i.e. before deenergizing the electronic control unit.
  • This second time duration is helpful in situations where the image display device remained in stand-by mode during which a loss of power occurred and power to the device was not manually shut off.
  • the image display device upon restoration of power, the image display device will typically execute the same method and enter in command mode in association with the method for operating the image display device according to the invention.
  • the second time duration preferably shorter than the first duration, such as fifteen seconds, is helpful to remind the users that instant screen-on function is currently active.
  • the sound indication in this case is a non-intrusive one in terms of the level, duration and character of the same.
  • said image display device if no user command is received within the pre-specified time period, said image display device generates a sound indication and the command mode is maintained for a second pre-specified time period being shorter than the first period.
  • the method of the present invention is advantageous in that a substantially quicker response time can be achieved by making the main components of the image display device operable in the background before a corresponding user command is received.
  • the command mode will remain active for a certain time duration such as one minute and the image display device will return to stand-by mode if no such user request is made.
