The present invention relates to an LED display clock, and more specifically, LED scales representing days, hours, minutes, and seconds indicate the current time by sequentially blinking or progressively lighting in a clockwise direction. Digital clock indicating remaining day / remaining time by inputting time and displaying hour or minute LED indicators or remaining indicators flashing or turning off sequentially in the opposite direction of current time It is about.

Conventional digital clocks that display time in numbers on the LCD window have been used a lot because anyone can easily determine the current time, but gradually became uncomfortable in other respects. In general, consumers don't just use the clock to determine the current time, but instead want to know the interval of time--how long has passed from a particular time, or how much time is left until that time. However, the digital clock which is displayed as a number in the conventional LCD window should read the time indicating the current time and subtract the specific time from the current time or vice versa to determine the time interval. It was difficult to grasp and easy to get wrong.

For example, as shown in FIG. 1, when the current time is 7:14:53, it is very easy to determine the current time. However, in order to determine how long the departure time has passed from 5:30, it is necessary to perform a subtraction calculation using the 60-degree method. It can be seen that it is about 1 hour and 45 minutes, and calculation is easy. It is also the same in calculating how much time is left for a scheduled appointment.

In addition, the conventional LCD clock or analog clock was not able to check the time properly in the dark, so the clock had to have a separate light.

On the other hand, consumers are no longer able to find the freshness of conventional digital clocks that express time in numbers, and they feel sick.

On the other hand, the LED display clock shown in Patent Publication No. 10-2003-0040247 Figures 2a and 2b can be referred to as a prior art, in FIG. 2a minute display LED scales are displayed in units of 5 minutes it is impossible to accurately determine the time In the case of expressing time in a bar graph format as shown in FIG. 2B, when the hour display scales representing 12 hours and the minute display scales representing 60 minutes are made of the same height, and the minute display scales are not 60, Accurate time grasping becomes difficult or impossible. In addition, the minute display scale 102 or the super display scale 103, which should be divided into 60 equal parts, is disposed inward than the time display scale 101, which is a 12th grade display, so that time grasp is very difficult. The applicant of the above-mentioned publication No. 10-2003-0040247 also acknowledges the fact in the application specification and is suitable for detecting rough time, and intends to implement the LED watch only for fashion. The LED display clock of the same manner as in FIG. 2B is more difficult to grasp time than a clock having time display scales arranged along its circumference with respect to the center of the time display.

In addition, conventional LED watches are not able to perform the date input, alarm function, timer function, and local time display function that can be added to the watch while emphasizing only the aesthetic sense. It did not meet. Conventional commercialized LED watches also had a problem in that the time setting must be updated every time the battery is replaced.

In addition, it was not possible to set up the scheduled time for managing the schedule or to display the remaining time or the remaining time from the current time to the specific time scheduled, so that the schedule could not be efficiently managed using the clock. It was not possible to input information about the place or the other party.

An object of the present invention is to solve the problems of the prior art.

The purpose of the present invention is to make it possible to quickly and easily grasp the elapsed time from a specific time and the remaining time up to a specific time as well as the present time, and to implement a more sophisticated LED display digital clock.

Another object of the present invention is to enable the setting and input of one or more scheduled dates / scheduled times, and to display the one or more remaining days / remaining time information according to the time display scales composed of LEDs for a refined and quick schedule. It is to implement manageable LED digital clock. In addition, it is possible to implement an LED digital clock that enables efficient schedule management by setting and inputting a scheduled place or counterpart information.

Another object of the present invention is easy to input the setting of various functions such as date input, alarm function, timer function, local time display function, and the function can be implemented, and there is no need to newly set the time when replacing the battery. Even if used, the LED digital clock has a low power consumption.

The present invention is a digital clock comprising an input unit, a control unit and a time display unit, consisting of two to four buttons type is provided on the periphery of the time display unit, the clock side or the watch band and present time, date information, alarm An input unit for inputting part or all of a time, a timer, and a local time, an auxiliary power supply for supplying auxiliary power to a memory, a CPU, and a real time clock, time information obtained from the real time clock, and the input unit The time information obtained from the memory is aggregated and stored through the CPU, time information received from the real time clock, time information received from the input unit, time information obtained from the information stored in the memory, and feedback from the time display unit. The received time information is synthesized and a control signal containing the integrated time information is generated to display the time display part. A control unit including a CPU to transmit and control inter-information, and 12 or about 12 minutes around the center of the time display unit to include 12 hours, including some or all of AM / PM, alarm, timer, and local time identifiers. Hour display scales consisting of LEDs, minute display scales consisting of 59 or 60 LEDs in the same center as the above, so as to indicate 60 minutes; In addition to the minute display scale so as to indicate 60 seconds, the second display scales composed of 59 or 60 LEDs in the same center as the above, wherein the time display scales of hours, minutes, and seconds are not known. Some or all of the size, shape or color to be easily made, and also the LED (LED) is sequentially flashing clockwise by the time information received from the control unit To ensure that light up progressively relates to a digital watch, characterized in that comprising an time indicator that indicates the passage of time.

In the case of three or four, the current time, You can specify buttons to set and check some of date information, alarm time, timer, and local time, which makes button operation much more convenient.

The auxiliary power supply supplies the auxiliary power to some components of the memory, RTC, CPU, and time display when the battery used as the main power supply is depleted and needs to be replaced. This eliminates the need for setting and allows the clock to run for a while even if the main power supply battery runs out.

The real time clock (RTC) generates pulses at predetermined time intervals to provide time information to the CPU.

The control unit controls to display the time set by sound or vibration at the alarm time set in accordance with the alarm time, timer, or local time setting input from the input unit, or has a timer function or local time according to the time difference according to the region. It may include controlling to be displayed by the time display.

Some or all of the AM / PM, alarm, timer, and local time identifiers can be displayed on the LED display through the LED display or the LCD window can be displayed for easy identification. do.

The time scales composed of LEDs can vary in bar shape, round shape, square shape, and size and color.

The time display scales can be progressively lit to make it easier to grasp time information as time progresses to indicate the current time, or alternatively to reduce power consumption in LEDs. The hour, minute, and second scales representing the previous time can be displayed in sequence by flashing in such a way that the scales are turned off and the next scales are lit.

If the minute or second indication scales consist of 60 pieces, one (1) or 1 minute after the 60th scale is turned on, the scale (s) of the existing minute or second indicators are turned off and the first scale is turned on. If 1 second or 1 minute has elapsed after the 59th scale is turned on, the scale (s) of the lit state of the existing minute or second display is turned off and the first scale is turned on again after 1 second or 1 minute, and 59 or In any of the 60 cases, at the same time as 60 seconds or 60 minutes have elapsed, the next scale is turned on at the upper time scales. That is, when 60 scales are used, the next sequence of the upper time display scales turns on at the same time as the 60th scale turns on, but when the 59 scales are used, the 59th scale turns off and at the same time, the upper time scale Of the next sequence will light up.

The present invention also in the above invention, the time display portion may further include a day display scale consisting of six or seven LEDs that can represent the day of the week as the center of the time display portion, the minute display scales are Divided into 12 directions, stratified within each bearing, it is arranged radially to represent 4 minutes within the last 12th orientation when there are 59 5 minute or minute scales. As a result, the flow of time may be indicated by sequentially flashing or progressively lighting outwards.

On the other hand, the time display unit may further include a day display scale consisting of six or seven LEDs that can represent the day of the week as the center of the time display, the time display scales bar at a constant angle to the same center (bar The scales of the minute or second bar may be configured by changing the colors of the 5 minute or 5 second scales and the remaining scales.

The day, hour, minute, second display scales may be arranged in various shapes such as circular, hexagonal, decagonal, square, semicircle, circular shape with a part of the upper or lower part of the same center as other shapes.

In the case of seven LED scales representing the day of the week, each day of the week may be represented, and in the case of six, Sunday may be marked as all lights out.

Day or time indication scales can be arranged in bar-shaped bar scales that go at the same angle to the same center. In this case, the appearance of time progress is beautiful and more sophisticated.

The minute scales may be arranged at an angle to the same center as the hour scales, or alternatively divided into 12 azimuths, the last 12th if there are 5 scales representing 5 minutes per bearing or 59 minute scales. In Eqs, you can also arrange radially so that four scales representing four minutes extend outwards. Arrangement divided into 12 directions is more clearly distinguished by 5 or 10 minutes rather than by arranging all the minute scales at regular intervals, so that the value representing the minute at the current time will be easily and accurately identified. .

On the other hand, the 5 minute or 5 second scales of the minute or second indication bar scales consist of LEDs having a different emission color from the remaining minute or second indication scales or by changing the color of the LED top cover. It will be divided into 5 seconds, making it easier, faster and more accurate.

The light emission of the LED may be made thin so that the light bleeding does not appear on the other scales, so that the accurate scale display without the light bleeding may be possible.

The present invention also in the above inventions, the buttons of the input unit may set and input one or a plurality of scheduled dates or scheduled time, may include a button for checking the remaining days / remaining time until the scheduled date or scheduled time When the input unit checks the remaining date / remaining time, the control unit may include one or more from one or more scheduled dates or scheduled time to a current date or current time which is changed according to time information transmitted from the real time clock and the memory. May be controlled to display information on the remaining day / remaining time of the time display unit, and the time display unit may further include a remaining day / remaining time identification unit. The time display scales are currently timed by one or a plurality of remaining time information from the controller. One or a plurality of remaining times may be indicated by sequentially blinking or extinguishing in the opposite direction to the row direction. On the other hand, when displayed as the remaining days on the time display unit, the hourly display graduations are controlled by the control unit. The minute indication scales arranged radially in the 12 directions are divided into 6 directions about the time display part, and each of the five layers, each of which has two graduations from the inside to the outside in each direction, is accumulated ( In the case of minute display scales that indicate the number of days or arranged at a constant angle around the time display part, the remaining days per two divisions are indicated, and the current time progression direction is reversed as one or more remaining days are passed. One or more remaining days may be indicated by flashing or turning off sequentially, and The LCD window may include one or a plurality of scheduled dates or a predetermined time input through the input unit, and may include a predetermined function setting and a remaining date / remaining time identification unit.

When the input setting for checking the remaining day / remaining time is made, the remaining day / remaining time will be displayed in the opposite direction to that of the present time. That is, in the case of minute display scales which are flashed or turned off in the opposite direction of the current time progress direction from the remaining day or the remaining time of the current reference, and particularly in the case of indicating the remaining time, the radial directions of the 12th direction are set to 12 degrees In the bearing, it will be sequentially flashed or turned off from the outside to the inside, and in the case of indicating the remaining days, the minute-division scales arranged radially in 12 directions are divided into the above 6 directions in each of the 5 directions. Will be flashed or turned off from outside to inside.

In the case of remaining days, twelve hour scales may represent the number of months remaining, and 59 or 60 minute scales may represent one day remaining per two graduations, in particular in a radial arrangement of 12 orientations. In the case of minute display scales, the five floors with two scales for each bearing represent one day for each floor, and the remaining days can be expressed up to 30 days. And remaining days.

Remaining day / remaining time display can be controlled to display the remaining day automatically if time minus current day / current time from scheduled date / scheduled time less than 12 hours or 24 hours or remaining day / remaining time The identification of the identification unit may be controlled to display the remaining days or the remaining time. Control criteria for displaying the remaining days or the remaining time may be predetermined or determined through a user's setting input. If the remaining time is more than 12 hours and less than 24 hours, and the remaining day / remaining time display control criterion is 24 hours, the identifier indicating the afternoon of the AM / PM identification part is turned on or displayed, and the remaining time is subtracted from 12 hours. Only time may be indicated in the timescales.

If a plurality of scheduled dates / scheduled times have been entered, the number may be displayed in the scheduled function setting identification unit, and in this case, if the setting of checking the remaining days / remaining time is set, the displayed scales are displayed in a progressive state. Instead of the display, only a plurality of corresponding scales may be turned on, respectively, and may be displayed in a state of sequentially blinking in the opposite direction of the current time progression direction as time passes.

In particular, when displaying a plurality of remaining times that are less than 12 hours or 24 hours, the hour and minute indication scales indicating the remaining time of the same contents among the time indication scales in which the remaining times are displayed are different from each other, for example, By differently representing the blinking time or the blinking time interval, it will be possible to confirm the plurality of remaining times, in which case it would be desirable to keep the seconds indication scales OFF.

Of course, even when a plurality of remaining days are displayed, the scales of the months and the remaining days indicating the same content may be displayed in the same manner as described above, and in the case where the plurality of remaining days are all within 30 days, there are no flickers. It can also be indicated by the lighting state of.

In addition, when the scales of the time display display the remaining day / remaining time, the LCD window may display the current time information, and on the contrary, the LCD window displays the remaining date / remaining time information and the time display scales display the current time. It can also be set to display.

The present invention also in the above inventions, the input unit may further include a button for setting and setting a predetermined place or counterpart information, the LCD (LCD) window of the time display unit is one that is input through the input unit Alternatively, a plurality of predetermined places or counterpart information may be displayed.

If there are two buttons in the input section, consonants and vowels are stored in the memory so that you can enter the location or counterpart information with the direction movement function, setting and input function, and each button itself increases as the number of buttons increases. It can be easily entered by allowing unique consonants and vowels to be assigned. If there are too many buttons, the shape of time may not be refined, so if you have three buttons for displaying consonants and three buttons for displaying vowels with cheonjiin (·, ＿, |), the appropriate number for place input It could be a button.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. The technical spirit and scope of the present invention will not be limited by the embodiments of the present invention.

Figure 3 shows a plan view of the time display of the LED display clock according to an embodiment of the present invention.

The time display unit 30 has twelve hourly display scales 31 arranged at a constant angle near the LCD window 40 and its surroundings at the center thereof, and 60 times arranged at a constant angle outside the scales at the same center. It is composed of the minute display scales 32 and the 60 second display scales 32 arranged at an angle outside the minute display scales, and the time display scales can be displayed as LED bar scales. have. In FIG. 3, the current time of 7:14:53 and the 24th date are displayed in the LCD window 40. FIG.

The 5 minute scales 32a and 5 second scales 33a are composed of LEDs that differ in emission color from the remaining minute or second display scales, or on top of the LEDs, so that time information of minutes and seconds can be easily and quickly obtained. The cover may be configured to be different in color with a cover of a different colored crystal or the like.

4A illustrates a plan view of a time display unit of an LED display watch according to another embodiment of the present invention.

The time display units 30a and 30b have an LCD window 40 at the center thereof, and six day display scales 34 arranged at regular intervals around the closest center thereof to indicate Monday to Saturday, Twelve hour display scales 31 arranged at regular intervals around the periphery of the day display scales 34 and 12 layers around the periphery of the city display scales 31 divided into five layers for each orientation. 60 minute display scales 32, which are easily distinguished by 5 minute units and represent 60 minutes in total, and are arranged at regular intervals to represent seconds around the periphery of the minute display scales 32. It is composed of sixty second indication scales 33.

The day display scales 34 and the time display scales 31, 32, and 33 are composed of LEDs to indicate the current time according to the lighting state. In FIG. 4A, all of the day display graduations 34 are not lit, indicating Sunday.

For example, the lighting state of the time display units 30a and 30b representing the current time of 7:14:53 is progressively lighted 35a of the hour, minute, and second display scales 31, 32, and 33. It may be the time display part 30a of the state, or the time display part 30b in which only the hour, minute, and second display scales corresponding to the current time are turned on. The minute display scales 32 are divided into 12 azimuths and 5 minutes for each bearing, unlike the hour or second display scales, so that the user can grasp the accurate time much more easily and accurately. In addition, when the boundary is 10 minutes, that is, the two directions will be more effective time grasp will be possible. On the other hand, in the case of the time display unit 30b expressing the present time so that only the corresponding time is progressive, the lighting number of the LED (LED) is reduced, so that much lower power will be consumed. Although not shown, the shapes of the time display units 30a and 30b may have various shapes such as a rectangle and a hexagon.

Figure 4b is a plan view of the LCD window 40 in the center of the time display portion of the LED display clock of an embodiment of the present invention.

In the LCD window 40, the AM / PM identification unit 41, the timer setting identification unit 42, the alarm setting identification unit 43, the scheduled date / scheduled time setting identification unit 44, the remaining day / remaining time identification unit 45, the local time setting identifying unit 46, the OFF function identifying unit 47, and the input status plate / time display plate 48 may be displayed.

The display of the identification units or the display of the input status plate / time display plate 48 may be set or input by the setting input buttons 10 in FIG. 5 or displayed on the LCD window 40 by the control of the controller. When there is a color display on the display of the identification unit, it may indicate that the mode is set, and the identification display modes that are not set differently from the illustration may not appear in the LCD window 40.

The OFF function identification unit 47 indicates an indication that the user has changed some functions of the present invention to the OFF mode by the setting input of the setting input buttons 10, and the setting input buttons 10 set the OFF function. You can enter For example, it is possible to set the states of the superdisplay scales to OFF, and to adjust other functions or the display state to the OFF state. Unlike in FIG. 4B, only some of the above identification units may be displayed in the LCD window according to a setting input like the LCD window 40 in FIG. 4C. Many functions not mentioned above, such as entering a scheduled location, can be displayed in the LCD window.

Figure 4c shows a time display unit for displaying the remaining days / remaining time in the LED display clock of an embodiment of the present invention.

For example, when the remaining time is displayed, the time display scales 31, 32, and 33 of the time display unit 30c have the same time display functions as the time display scales indicating the current time, but only the control of the controller. By the direction of progress of the lighting state is the opposite direction to the current time progress, in the case of minute display scales 32 can be displayed to turn off sequentially from the outside inward in each of the 12 azimuths. For example, if the current time displayed on the input status plate / time display 48 is 07:14:53 and the scheduled time (schedule) is 12 o'clock on the same day, the remaining time is 4 hours 45 minutes and 7 seconds. Although not shown, the hour, minute, and second display scales corresponding to the remaining time may be sequentially flashed in the reverse direction of the current time progress direction according to the control information.

In addition, in the time display unit 30d in the case of indicating the remaining days, the time display divisions indicating the current time under the control of the controller will be scales indicating the remaining months and the remaining days. That is, the hour display scales 31 will be changed to scales 31b representing the remaining months, and the minute display scales 32 will be changed to scales 32b representing the remaining days. In this case, it is preferable that the existing second indication scales are turned off. The scales 32b representing the remaining days are divided into six directions and within each orientation can consist of five layers, one layer per two graduations, and two graduations on the same floor within the same orientation are dependent upon the change in the remaining days. At the same time, the lights turn on or off at the same time, and according to the decrease of the remaining days according to the remaining time information from the controller, the present time is sequentially flashed or turned off from floor to floor in each direction, and the current time is decreased by 5 days in all six directions. It will proceed in the opposite direction. Seven days of remaining days are shown in the remaining time display section 30d. Although not shown, the months and remaining days display scales 31b and 32b are not progressive, and only the display scale corresponding to the corresponding month or day may be displayed in a lit state, in which case a plurality of remaining days may be displayed. Will be done. In the case of indicating the remaining days / remaining time, it can be seen that the minute indication deposits are divided into six directions and turned on or off by two scales for each floor within each direction, and the remaining days / remaining periods are checked in the LCD window 40. It may be easily distinguished from indicating the present time by whether or not the indicating unit 45, for example, the display 45 of "RES" is shown. Alternatively, when the current time displayed on the input status plate / time display 48 of the LCD window 40 and the time indicated by the time display scales are different, the display of the time display scales may be recognized as the remaining day / remaining time display.

Figure 5 shows a perspective view of the LED display wrist watch of an embodiment of the present invention.

There is an input 10 around the time display, and four buttons are shown. For example, the lower left button 10a may be a button for setting a mode, the lower right button 10b may be a button for confirming or inputting a selected mode, and the upper two buttons 10c and 10d may be buttons. Each may be a directional button, or each of the buttons 10a, 10b, 10c, and 10d may have other functions such as text input.
