Description

  The present invention relates to an LED display clock and a time display method thereof. More specifically, the present invention relates to an LED scale indicating a day of the week, an hour, a minute, and a second by sequentially blinking or progressively lighting in a clockwise direction. , Enter the scheduled date / time, and set the remaining date / remaining time confirmation settings so that the LED scale indicating the hour or minute or the LED scale indicating the remaining date blinks or goes off sequentially in the opposite direction of the current time. The present invention relates to a digital clock indicating a remaining date / time and a time display method thereof.

  Conventional digital clocks that display numbers in an LCD window have been used a lot because it is possible for anyone to easily grasp the current time, but they gradually feel inconvenient in other ways. became. In general, consumers do not simply use the clock to keep track of the current time, but rather the time interval, i.e. how much time has passed since a certain time, or how much time remains until a certain time. I want to know. However, digital clocks that are displayed numerically on the conventional LCD window must read the time indicating the current time and subtract the specific time from the current time, or vice versa, to grasp the time interval, In such a method, it was difficult to grasp the time interval immediately and quickly, and it was easy to make a mistake.

  For example, as shown in FIG. 1, when the current time is 7:14:53, it is very easy to grasp the current time, but how long the departure time has passed since 5:30 In order to grasp, it is possible to know that it is about 1 hour 45 minutes after subtraction in the 60-decimal system, and the calculation is easy to make mistakes. The same is true when calculating how much scheduled time remains.

  In addition, since the conventional LCD clock and analog clock cannot accurately check the time in a dark place, the clock must be provided with a separate light.

  On the other hand, consumers can no longer search for the freshness of traditional digital watches that show time in numbers, which makes them bitter.

  Meanwhile, as shown in FIGS. 2A and 2B, Korean Patent Publication No. 10-2003-0040247 discloses a conventional LED display watch. As shown in FIG. 2A, the minute display LED scale is provided in units of 5 minutes, and accurate time grasping is impossible, and even when the time is expressed in a bar graph format as shown in FIG. 2B. When the hour display scale indicating 12 hours and the minute display scale indicating 60 minutes are the same height, if the minute display scale is not formed with 60 pieces, accurate time grasping is difficult or impossible. . Further, when the minute display scale 102 and the second display scale 103 that should be divided into 60 equal parts are arranged on the inner side of the display scale 101 when the display is the 12th class display, it is very difficult to grasp the time. The applicant of the above-mentioned 10-2003-0040247 also recognizes such fact in the application specification and says that it is suitable for sensing the time approximately, but intends to implement an LED watch for fashion use. . The LED display timepiece of the type as shown in FIG. 2B is more difficult to grasp the time more reliably than a timepiece in which time display scales are arranged around the center of the time display portion.

In addition, the conventional LED clock emphasizes only the aesthetic sense, and since it cannot perform date input, alarm function, timer function, local time display function, etc. that can be added by the clock, it is diverse with sophisticated beauty. It did not meet the expectations of consumers trying to secure functionality. Conventional commercialized LED watches have a problem that the time setting must be renewed every time the battery is replaced.
In addition, there is no function to set and input the scheduled time so that the schedule can be managed, and to display the remaining time and the remaining date from the current time to the scheduled specific time. It was impossible to manage the schedule properly, and it was impossible to input information to the place and the other party according to the promised time.

An object of the present invention is to provide an LED display timepiece for solving the above-mentioned problems of the prior art.
Another object of the present invention is to make it possible to easily and quickly grasp not only the current time but also the elapsed time from the specific time and the remaining time until the specific time, and further refine the LED display digital clock. It is to implement.
Still another object of the present invention is to allow one or a plurality of scheduled dates / scheduled times to be set and input, whereby one or a plurality of remaining days / residual time information is displayed by LEDs. An LED digital clock that can be displayed on a scale and can be refined and quickly managed can be realized. Another object of the present invention is to implement an LED digital timepiece that can set and input a planned location or counterparty information and enables efficient schedule management.
Still another object of the present invention is to easily set and input various functions such as date input, alarm function, timer function, and local time display function, and the functions can be realized. Therefore, it is necessary to implement an LED digital timepiece that consumes less power even when LEDs are used.

  In order to achieve the above object, the present invention provides a digital timepiece having an input unit, a control unit, and a time display unit, which is composed of two to four buttons, and around the time display unit and the side of the clock. Or an input unit provided on the clock band for setting and inputting a part or all of the current time, date information, alarm time, timer, and local time, and auxiliary for supplying auxiliary power to the memory, CPU and real-time clock (RTC) A power supply device, a memory in which time information obtained from the real time clock and time information obtained from the input unit are integrated and stored through a CPU, time information transmitted from the real time clock, from the input unit The time information obtained from the time information obtained from the information stored in the memory and the time information fed back from the time display unit Including a control unit including a CPU for generating a control signal including information and transmitting and controlling time information to the time display unit, and a part or all of an AM / PM, alarm, timer, and local time identification unit, A time scale composed of 12 LEDs around the center of the time display unit so that the time can be indicated, and 59 or 60 LEDs at the same center as the outside of the time display scale. The minute display scale and the second display scale composed of 59 or 60 LEDs at the same center as the outer part of the minute display scale so as to indicate 60 seconds, The time display scale for minutes and seconds is different in size, shape, or hue so that the time can be easily grasped, and the LED is transmitted according to the time information transmitted from the control unit. And time display unit showing the flow of time so as to be sequentially flashing or progressively lit meter direction, a digital clock that characterized in that it comprises a.

  When the input unit is composed of two buttons, one button performs setting, input or confirmation, and timer stop function, and the other one performs direction movement and timer start function. In the case of three or four, it is also possible to specify buttons for setting and checking a part of the current time, date information, alarm time, timer, and local time, so it is more diverse and You can operate buttons conveniently.

  The auxiliary power supply replaces the battery by supplying auxiliary power to a part of the memory, RTC, CPU and time display unit when the battery serving as the main power supply device is exhausted and must be replaced. The time is not required to be set later, and the clock can be operated for a predetermined time even when the battery as the main power supply device is exhausted.

  A real time clock (RTC) provides time information to the CPU by generating pulses at predetermined time intervals.

  The control unit performs control so that the time set by sound or vibration can be displayed at the time of the alarm time set by the setting input of the alarm time, the timer, or the local time using the input unit. Alternatively, it may include a timer function, or control to display the local time on the time display unit so as to match the time difference depending on the region.

  Some or all of AM / PM, alarms, timers, and local time identification units can be shown in a lit state through the LED or equipped with an LCD window on the time display unit. Becomes easier.

  The time display scale composed of LEDs can be various shapes such as a bar shape, a circular shape, and a regular square shape, and the size and hue can be varied.

  The time display scale can be progressively lit to indicate the current time so that it is easier to grasp the time information as time progresses, or alternatively, it can be indicated by an LED. In order to be able to reduce power consumption, the hour, minute, and second scales indicating the previous time are turned off, and the time is displayed in such a manner that the next scale is turned on and blinks sequentially. be able to.

  When there are 60 minute or second display scales, after the 60th scale is lit, the existing minute or second display lit scale is extinguished and the first scale is lit when 1 second or 1 minute has passed. When the 59th scale is turned on, the scale of the existing minute or second display lighting state is turned off when one second or one minute has elapsed after the 59th scale has been turned on, and when one second or one minute has passed. The first scale is lit, and in either case of 59 or 60, the next scale is lit on the upper time display scale as soon as 60 seconds or 60 minutes have elapsed. . That is, when 60 scales are used, the next sequential scale among the upper time display scales is lit simultaneously with the lighting of the 60th scale, but when 59 scales are used, 59 At the same time as the second scale is turned off, the next sequential scale among the upper time display scales is turned on.

  In the present invention, the time display unit may further include a day of the week display scale composed of six or seven LEDs capable of indicating a day of the week at the center of the time display unit. If it is divided into azimuths, layered in each azimuth and has 5 minutes or 59 minute display scales, they are arranged radially to show 4 minutes in the last 12th azimuth, Within each azimuth, the time flow can be shown by sequentially flashing or progressively turning outward in accordance with time information.

  Meanwhile, the time display unit may further include a day display scale composed of six or seven LEDs capable of indicating a day of the week at the center of the time display unit, and the time display scale is in the same center. The minute or second display bar scale can have a color different from the 5 minute or 5 second unit scale and the remaining scale colors.

  The day, hour, minute, and second display scales have various shapes such as a circle, a hexagon, a dodecagon, a rectangle, a semicircle, and a circle whose upper end or lower end is partially opened. Can be arranged.

  When there are seven LED scales indicating the day of the week, each day of the week can be indicated. When there are six LED scales, Sunday can be displayed when all are off.

  The day or time display scale can be arranged in a thin bar-shaped bar scale at a predetermined angle with respect to the same center. In this case, it is possible to look beautiful and refined in a tidy form of time progression.

  The minute display scales can also be arranged at a predetermined angle with respect to the same center as the hour display scale, and alternatively, five scales that are equally divided into 12 directions and show 5 minutes per direction, or If the minute display scale is 59, the four scales representing 4 minutes in the last 12th can be arranged radially so as to extend outward. Arranging in 12 orientations makes it easy to determine the value of the minute at the current time, because the minute display scale is arranged at regular intervals, so that the division in units of 5 minutes or 10 minutes becomes clear. To be able to grasp.

  On the other hand, the 5-minute or 5-second scale of the minute or second display bar scale is composed of LEDs having emission colors different from the remaining minute or second display scales, or the LED upper cover color is different. Thus, the time is divided in units of 5 minutes or 5 seconds, and the time can be grasped more easily and quickly.

  In the present invention, the time display unit may include an LCD window at the center of the time display unit or the lower part of the outermost time display scale in the front part of the timepiece, and the LCD window is provided by the auxiliary power supply device. Auxiliary power is supplied and time or date information set and input through the input unit can be indicated, and can be shown including part or all of the AM / PM, alarm, timer, and local time identification unit. it can.

  By providing an LCD window, it is possible to easily check the input state at the input unit and the states of various identification units, and by supplying auxiliary power to the LCD window, various types displayed on the LCD window The information shown on the identification display is fed back to the CPU even when the battery is replaced.

  The LCD window has a function OFF identification unit, and the operation of the second display scale or a part of the display state of another time display unit can be maintained in the operation OFF state by setting input of the input unit. In addition, setting input of other functions can be included, and the state of such functions can be expressed by the LCD window.

  In the present invention, a block for blocking the spread of light may be formed between the scale and the scale on the back surface of the scale plate on which the day of the week or the time display scale is displayed.

  The button of the input unit can set and input one or more scheduled dates or scheduled times, and can include a button for confirming the remaining date / time remaining until the scheduled date or scheduled time, and the control unit 1 to the one or more scheduled dates or scheduled times from the current date or the current time changed according to the time information transmitted from the real time clock and the memory when the input unit confirms the remaining date / time. One or a plurality of remaining days / remaining time information can be controlled to be displayed on the time display unit, and the time display unit can further include a remaining date / remaining time identifying unit, When displayed as a remaining time on the display unit, the time display scale is sequentially turned in the opposite direction of the current time according to one or more remaining time information from the control unit. Alternatively, one or a plurality of remaining times can be indicated so as to be turned off. On the other hand, when the remaining time is displayed on the time display unit, the time display scale is controlled by the control unit. The minute display scales indicating the number of months and arranged radially in the 12 azimuth directions are divided into 6 azimuths centering on the time display portion, and within each azimuth, 2 scales are collected 2 from the inside toward the outside. Each of the layers indicates the number of remaining days, or in the case of a minute display scale arranged at a predetermined angle around the time display portion, indicates one remaining day per two scales, and one or more One or a plurality of remaining days may be indicated by sequentially flashing or turning off in the opposite direction of the current time as the remaining days elapse, and the LCD window of the time display unit may include the input unit. Through been able to show one or more of date or scheduled time is input may include a schedule function setting and residual date / remaining time identifying unit.

  When the input setting for confirming the remaining date / remaining time is made, the remaining date / remaining time is displayed in the opposite direction to displaying the flow of the current time. That is, in the case of the minute display scale arranged in a radial direction of the 12 directions in the case of flashing or extinguishing in the opposite direction of the current time from the current reference remaining date or remaining time, particularly in the case of indicating the remaining time, the 12 directions In each of the azimuths, when blinking or extinguishing sequentially from the outside to the inside and indicating the remaining days, when the minute display scale arranged in 12 azimuths is divided into the six azimuths, It is displayed so as to blink or turn off from the outside to the inside in each direction.

  When displayed as a remaining day, the 12 hour display scale may indicate the number of remaining months, and the 59 or 60 minute display scale may indicate one remaining day per two scales. In particular, in the case of a minute display scale arranged radially in 12 directions, 5 layers are divided into 6 directions and 2 scales are collected for each direction so that one day is shown for each layer. Thus, the remaining number of days can be expressed up to a maximum of 30 days, and in the case of more than that, it can be expressed by the number of remaining months and the number of remaining days by an inverse calculation method.

  The display of the remaining date / remaining time is controlled so that the time display unit automatically displays the remaining date when the time obtained by subtracting the current date / current time from the scheduled date / scheduled time is 12 hours or 24 hours or more. Or it can be controlled to display the remaining date or remaining time through confirmation of the remaining date / remaining time identifier. The control criteria to be displayed by the remaining date or the remaining time can be determined in advance or can be determined through a user setting input. When the remaining time is 12 hours or more and less than 24 hours, and the remaining day / residual time display control standard is 24 hours, the identification unit indicating the afternoon of the AM / PM identification unit is turned on or displayed. Only the remaining time obtained by subtracting 12 hours from the remaining time can be displayed on the time display scale.

  When a plurality of scheduled dates / scheduled times are input, the number can be displayed in the scheduled function setting identification unit. In this case, if the remaining date / remaining time confirmation is set and input, the display scale is changed. The remaining date / time is not displayed in a progressive state, and only a plurality of scales corresponding to the remaining date / time are lit, and sequentially flashed in the opposite direction of the current time as the time passes. it can.

  When displaying a plurality of remaining times of 12 hours or less than 24 hours, among the time display scales where the remaining time is displayed, the time when displaying the remaining time of the same content and the lighting state of the minute display scales are shown differently, for example, It is possible to check multiple remaining times by being lit, blinking, or by showing different blinking time intervals, in which case the second display scale is in the OFF state It is preferable to do so.

  When a large number of remaining days are displayed, the scale of the number of months and the number of remaining days showing the same contents can be displayed in the above-described manner, and when the plurality of remaining days are all within 30 days, It is also possible to indicate only a number of lighting states that do not sparkle.

  When the scale of the time display section displays the remaining date / remaining time, the LCD window can display the information of the current time, and on the contrary, the LCD window displays the remaining date / remaining time information and displays the time. The scale of the part can also be set to display the current time.

  In the present invention, the input unit may further include a button for setting and inputting a planned location or opponent information, and the LCD window of the time display unit is one or a plurality of planned locations that are input through the input unit. Or the other party information can be shown.

  When there are two buttons on the input unit, consonants and vowels are stored in the memory, and the planned location or the other party information can be input with the direction moving function and the setting and input function. As the number increases, unique consonants and vowels can be assigned to each button itself, and can be easily input. If there are too many buttons, a refined shape can not be obtained, so if you have three buttons for displaying consonants and three buttons for displaying vowels equivalent to heaven, earth and people, It can be an appropriate number of buttons to enter a location.
