Description

System and Method for operating of Image display device

The present invention relates to a method and system for driving a video display device that shows a user a fast power-on function to enable a user to view an image more quickly.

In the recent home theater era, the popularization of 40-inch or larger projection TVs or projectors used in general companies or public buildings has made it possible for general households to watch broadcasts through such projection display devices.

As such, projectors and projection TVs have been widely used in general households, and their development and production have increased as products using LCDs to increase brightness and clarity. Since the lamp is the decisive factor that determines the brightness and size of the projector and the projection TV, there is a demand for miniaturization and high brightness of the lamp.

In the home use of the projection TV, the reliability, lifespan, and stability must be ensured above all, and when performing frequent power on / off functions, the start-up and restart operations must be performed quickly. It is essential to perform the cooling function for lamp life and correct operation at lamp on.

1 is a flowchart illustrating a method of driving a conventional video display device.

Referring to FIG. 1, the video display device determines whether power is on in a standby mode state (S100).

When the power is turned on in the standby mode as a result of the determination of step 100, the video display device drives the cooling fan for a predetermined time (S102).

Then, the video display device determines whether the predetermined predetermined time has elapsed (S104).

If the predetermined time elapses as a result of the determination in step 104, the video display device turns on the lamp (S106) and then displays the video signal (S108).

After performing step 108, the video display device determines whether the power is turned off (S110), and when the power is turned off, the step ends.

However, the conventional video display device as described above is to rotate the cooling fan for a predetermined time when the power is supplied to cool the inside of the set, and then to turn on the lamp, so that the user can watch the TV until the lamp is turned on There is an inconvenience to wait a long time.

In addition, when a user wants to watch TV, regardless of whether the previous state is normally powered off or abnormally powered off, the unnecessary time is wasted by driving the fan for a predetermined time and then lighting the lamp. There is a problem of increasing power consumption.

Accordingly, it is an object of the present invention to provide a method and system for driving a video display device that enables a user to view an image more quickly by showing a quick power on key on a remote control in a projection TV using a lamp.

Another object of the present invention is to provide a method and a system for driving a video display device to efficiently use a power source when the video display device is powered on.

Figure 2a is a block diagram schematically showing the configuration of a TV system according to an embodiment of the present invention.

Referring to FIG. 2A, the TV system is divided into a TV area 200 and a remote control area 250.

First, the TV area 200 will be described.

The TV area 200 includes a lamp 202, a microcomputer 204, an IR transmitter 206, an IR receiver 208, a storage 210, and a power unit 212.

In addition, the microcomputer 204 checks the time by driving a timer when the TV lamp 202 is turned off and in a standby state.

Accordingly, the microcomputer 204 determines whether the obtained time difference is greater than or equal to a preset time by obtaining a difference between the current time and the powered off time when the TV system is powered off. If the determined time difference is greater than or equal to the preset time, the microcomputer 204 transmits a lamp ready signal to the remote controller area 250.

Here, the lamp ready signal is a signal saying that the lamp 202 is cooled to an appropriate temperature, and indicates that it is in a fast power-on mode.

The IR transmitter 206 transmits a lamp ready signal transmitted from the microcomputer 204 to the remote controller 250, and the IR receiver 208 transmits a power control signal transmitted from the remote controller 250. To 204.

The key input unit 252 transmits the key selection information input by the user to the microcomputer 256. In particular, the key input unit 252 includes a fast power on key and a general power on key. If the fast power on key is a lamp ready signal is transmitted from the TV area 200 and the LED 260 is in a light emitting state, the user recognizes the fast power on mode and uses the quick power on key to power without driving the cooling fan. You can turn on immediately.

If the user selects the general power on key, the lamp 202 is turned on after the cooling fan is driven for a predetermined time.

The IR receiver 258 transmits a lamp ready signal transmitted from the TV area 200 to the microcomputer 256.

The IR transmitter 254 transmits a command input by the user through the key input unit 252 to the TV area 200.

The microcomputer 256 transmits a light emission signal to the LED 260 in response to the lamp ready signal transmitted from the IR receiver 258.

The LED 260 emits light corresponding to the emission signal transmitted from the microcomputer 256.

According to another embodiment of the present invention, the LED may be installed in the TV area 200.

Hereinafter, the operation of the TV system configured as described above will be described.

After the TV system is powered off, the microcomputer 204 of the TV area 200 obtains a time difference between the current time and the power off time stored in the storage 210, and then determines whether the time difference is greater than or equal to a preset time. Determine whether or not.

If the determined time difference is greater than or equal to a preset time, the lamp preparation signal is transmitted to the IR transmitter 206.

Then, the IR transmitter 206 transmits the lamp ready signal to the microcomputer 256 through the IR receiver 258 of the remote controller 250. The microcomputer 256 emits the LED 260 in response to the lamp ready signal, and determines whether fast power-on selection information is received from the user through the key input unit 252.

As a result of the determination, when the fast power-on selection information is received from the user, the microcomputer 256 transmits the fast power-on selection information to the IR receiver 208 of the TV area 200 through the IR transmitter 254.

Then, the IR receiver 208 transmits the transmitted fast power on selection information to the microcomputer, and the microcomputer 204 turns on the relay according to the fast power on selection information and then turns on the power.

Figure 2b is a block diagram schematically showing the configuration of a TV system according to another embodiment of the present invention.

Referring to FIG. 2B, the TV system is divided into a TV area 200 and a remote control area 250.
