The present invention relates to a method of displaying the current time when the VCR is powered off, and more particularly, to all VCRs to which an FLT or LCD (hereinafter, an LCD is applied) is applied to the LCD when the power is turned off. The present invention relates to a display method capable of adding a lift date, a lunar date and a day of the week on an LCD by controlling a timer control means by using a time point.

In the conventional VCR, the current time display method displayed when the power is turned off on the function display window made of the LCD is performed when the user turns off the power according to the current time on the OSD screen through a key input means provided in the remote control or the VCR set. Since the power supplied to the power supply is cut off and power is supplied only to the timer control means, the timer control means supplies power to the function display window through the LCD output port indicating the current time. The technology could only know the current time, not the date and day of the week.

The present invention has been made to complement the prior art as described above is an object of the present invention when displaying the current time on the LCD through the function display window and the solar calendar date and lunar date corresponding to the current time when input on the OSD screen And input the day of the week and add an output port to control the date and day of the week in the timer control means, so that the current time, as well as the solar date, lunar date, day of the week to display the function display window To provide a time display method.

A feature of the present time display method when the VCR is powered off according to the present invention for achieving the above object is to sequentially input time / date / day by searching for a menu selection key for selecting OSD display contents and functions. A second step of displaying an OSD guide screen; and a second step of receiving and storing a current time / date / day in the OSD guide screen display state of the first step and displaying the OSD guide screen again; When the power is turned off by detecting the status, turn off the power to all other functions, supply power to the function display window from the timer control means, and display the current time on the LCD. When the content change key is pressed, the display content is selected and displayed on the LCD in the order of current time / solar date (lunar date) / day depending on the number of times the content change key is pressed. Claim is made of an in 4 steps.

Hereinafter, a preferred embodiment of the present time display method when the VCR is powered off according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a block circuit diagram schematically showing a part of a configuration for implementing a current time display method when a VCR is powered off according to the present invention. As shown in the drawing, menu selection for selecting OSD display contents and functions from the outside is shown. A key input unit (1) having a display content switching key and a plurality of digit keys for switching keys and LCD display contents, and a key selection signal controlled by the key input unit to search the OSD processing unit and the timer control unit to supply power. A main controller 3 which checks the state and controls the power supplied to the timer controller, and a timer controller which stores and counts the current time / date / day given by the control signal of the main controller and controls the power supplied to the LCD display. (5), an OSD processing unit (7) for processing the corresponding display contents in accordance with the control signal output from the main control unit (7), and the timer It was composed of a LCD display (9) for selectively displaying a current time / date / day of by the unit.

2 is an operation flowchart showing an embodiment of a method for displaying the current time when the VCR is powered off according to the present invention. As shown in the drawing, the first step includes a menu selection key for selecting OSD display contents and functions. Searching step (S11), checking whether the time input function selection key is pressed (S12), and when the check result time input function selection key is pressed, the current time / date / day of the week can be sequentially inputted. Displaying an OSD guide screen (S13), the second step is to check whether the current time / date / day is input in the OSD guide screen display state of the first step (S14), and the check As a result, when the current time / date / day is input, it is received and memorized and displayed again on the OSD guide screen and the LCD (S15). The third step includes detecting a power supply state (S16), and checking Result power If so, the power supply to all other functions is cut off, and power is supplied from the timer control means to the function display window to display the current time on the LCD (S17). In step S18, when the search result display key is pressed, the corresponding display content is selected and displayed on the LCD in the order of the current time / the lunar date (lunar date) / day of the week according to the number of times the display content switch key is pressed. Preferably, step S19.

Referring to the configuration as described above when the operation of the present time display method when the VCR power off according to the present invention will be described.

First, when the user operates the VCR using the menu selection key (time input function selection key) of the key input unit 1 of the remote control or the VCR set to input the time / date / day (Y branch of S12), While the VCR is operating, the main controller 3 controls the OSD processing unit 7 to display an OSD guide screen for sequentially inputting time / date / day of the week to the screen of the TV (S13). Next, when the user presses the digit key of the key input unit 1 to match the current date (including the lunar and lunar calendar) and the day of the week and the day of the week (Y branch in S14), the main control unit 3 At the same time, the control unit 5 controls the timer control unit 5 to store and count the currently set data, and also sends the currently set data to the LCD display unit 9 so that the LCD display unit 9 automatically outputs the current data (S15). ) Next, when the power is turned off (Y branch in S16), the main controller 3 detects the power off state, cuts off the power supplied to all other functions, and controls the timer control unit 5 so that the timer control unit 5 controls the timer control unit 5. Power is supplied to the LCD display unit 9, which is a function display window, and the current time is displayed on the LCD (S17). Then, the main control unit 3 searches for the key control state by the external user through the key input unit 1, and when the display content switching key is pressed (Y branch of S18), the current time according to the number of times the display content switching key is pressed. By selecting the display content in the order of / lunar date (lunar date) / day of the week (S19), you can check the time / solar date (lunar date) / day of the week according to the operation of the display content switch key .

As described above, according to the present time display method of powering off the VCR according to the present invention, an output port for inputting a solar date and a lunar date and day corresponding to the current time and controlling the date and the day of the week in a timer control means is provided. By adding, the solar power date and the lunar date and the day of the week as well as the current time at the time of power off can be displayed alternately to the function display window to provide convenience to the user.
