Description

All-optical scale display with LCD display panel {LCD ELECTRO-OPTIC SCALED CLOCK}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display clock, and more particularly, to an all-optical display that displays current time by driving hour, minute, and second display scales using a liquid crystal display panel.

In general, there are two types of devices that show the change of time: the hour hand, minute hand, and second hand clocks that display the time by rotating the hour hand, and the digital all-optical clock that displays the time directly in Arabian numbers through the display panel. Watches are widely known.

All-optical digital clocks have been used a lot because they are easy to grasp the current time, but gradually became uncomfortable in other ways. Instead of simply using the clock to determine the current time, consumers want to know the interval of time: how much time has elapsed from a certain time, or how much time is left until a certain time.

However, the conventional all-optical clock should read the time indicating the current time and subtract a certain time from the current time or vice versa to determine the time interval. This method is difficult to determine the immediate and rapid time interval and is wrong. It was easy.

The liquid crystal display panel 100 and the circuit board 168 are connected by the zebrago 161, and the light source 166 and the circuit board 168 are connected by the light source terminal 167. Although zebragomu is used as the light source terminal 167, a spring may be used.

The battery 164 is fixed to the circuit board 168 so that the battery 164 becomes an energy source of the all-light graduation display clock 30 including the liquid crystal display panel 100. In addition, a circuit board 168 may be provided with a flexible printed circuit board (FPC) (not shown) for a switch, and a switch board (not shown) having a button such as a power switch button may be further connected to the FPC.

In addition, an LCD controller driver chip 205 for applying a predetermined signal to the signal electrode 102 and the data electrode 105 may be provided by the chip-on-glass mounting method. Each signal electrode or data electrode of the dot matrix display unit (display area) 113 or the segment display unit 40 is connected to the LCD controller driver chip 205 by a signal electrode connection electrode (not shown), and the LCD controller driver chip ( It is driven by the applied voltage supplied from 205. In addition, the LCD controller driver chip 205 is connected to the circuit board 168 through a connection line 207.

As shown in FIG. 5, the signal electrode 102 is electrically disposed on the signal electrode connection electrode provided on the second substrate 104 through an anisotropic conductive adhesive prepared by dispersing conductive grains in the sealing material 109. In addition, as shown in FIG. 2, a signal electrode for driving the segment display unit 40 may be disposed on the second substrate 104 through an anisotropic conductive adhesive. The external signal of the LCD controller driver chip 205 is input through an input electrode (not shown) provided on the second substrate 104.

The liquid crystal module including the LCD controller driver chip 205, the liquid crystal display panel 100, the circuit board 168, the light source 166, and the holding frame 210 is installed in the watch case 261. The liquid crystal module is shielded by the front cover 262 and the rear cover 263 to be protected from the external environment. The front cover 262 is a support member 262-1 fixed to or fastened to or detachably attached to the watch case 261, and a transparent member 262-2 fastened to the support member 262-1. ). On the front surface of the support member 262-1, twelve Arabian numerals indicating time are described at regular intervals. The transparent member 262-2 is made of a transparent material such as glass to externally recognize the current time displayed on the liquid crystal display panel 100.

As shown in FIG. 1, regions other than the region where the segment display unit 40 and the dot matrix display unit 113 are to be formed are distinguished from the current time displayed on the segment display unit 40 and the dot matrix display unit 113, respectively. It needs to be processed in a black state or a white state.

To this end, one proposed method is to implement the segment display unit 40 and the dot matrix display unit 113 in separate pixel arrays. In this case, each pixel array is simultaneously implemented in the liquid crystal display panel 100. Of course, a plurality of pixel units 107 are provided in the pixel array to display the current time. In this method, the regions between the segment display section 40 and the dot matrix display section 113 are substantially spaced apart from each other at regular intervals, and since no pixel portion displaying three primary colors is provided in this region, the black state is subject to the processing. Or white.

Alternatively, the segment display unit 40 and the dot matrix display unit 113 may be implemented in one pixel array, and the segment display unit 40 and the dot matrix display unit 113 may be formed on the pixel array corresponding to the area between the segment display unit 40 and the dot matrix display unit 113. As described above, the shielding layer 136 is formed. In this case, the shielding layer 136 may be formed in parallel with the color filter 103 as shown in FIG. 5. In addition, the shielding layer 136 may be formed on the same layer as the color filter 103. The shielding layer 136 may be formed in a line shape or a circle according to the shape of a watch as shown in FIG. 3. It may also be formed in the form of a bar or dot. The double dot form is suitable for use in the case of treating the area between the respective graduations in a black state.

These methods can also be applied to processing the area between the time display divisions 31, the division display divisions 32, and the super display divisions 33 formed in the dot matrix display section 113 in a black state or a white state. Can be. For example, the shielding layer 136 is formed in the region between the time display scales 31, the minute display scales 32, and the initial display scales 33, as shown in FIG. The area between the time scales 31, the minute display scales 32, and the second display scales 33 may be controlled to be maintained in a black state so that the three primary colors are not displayed.

In the same manner as the black state or white state processing method described above, three primary colors are displayed between the respective graduations of the time display divisions 31, the division display divisions 32, and the super display divisions 33. The shielding layer for blocking the thing may be provided in the form of a dot. In this case, the shielding layer may be disposed on the same layer as the color filter 103 or disposed above the color filter 103. Such a shielding layer may use any material that blocks light to block the display of three primary colors. For example, there is using chromium (Cr) having a property of blocking light with a shielding layer.

On the other hand, as a method of not using the shielding layer, there is a method of controlling the driving method. In other words, all of the graduations are simultaneously illuminated by the liquid crystal display panel 100, and the current time may be distinguished by differently expressing colors of the remaining graduations and the colors indicating the current time. In other words, the scales indicating the current time are displayed in red when fully lit, and the remaining scales are displayed in a color distinguishable from the scales displaying the current time, such as black or white when fully lit. This method can be applied not only to the respective scales but also to the area between the time display scales 31, the minute scales 32, and the initial display scales 33. FIG.

In addition, in order to provide the user with a reading of the current time more quickly, each of the five divisions of the division scales 32 and the sub-division scales 33 are different in color or in contrast to be dark or light. It may be provided to be displayed in color. For example, four scales (1 to 4) are sequentially controlled to be displayed in the same color, and the next scale, the fifth scale, is controlled to be displayed in a different color. In this way, the minutes and seconds of the current time can be classified every 5 minutes or 5 seconds to further improve the discrimination.

The all-optical scale display clock 30 according to the embodiment of the present invention configured as described above is clockwise in response to a signal selectively provided between the signal electrode 102 and the data electrode 105 from the LCD controller driver chip 205. The current etching information is displayed through the respective scales of the time display divisions 31, the division display divisions 32, and the second display divisions 33 which are sequentially illuminated one by one gradually or progressively. That is, the plurality of pixel units corresponding to the respective graduations are driven in response to a signal provided from the LCD controller driver chip 205, and correspondingly, each of the graduations is progressively progressively or progressively forwarded one by one in the clockwise direction.

6 is a plan view showing another example of the all-optical scale display clock according to an embodiment of the present invention.

Referring to FIG. 6, like the display clock 30 shown in FIG. 1, the all-light scale display clocks 30a and 30b include a segment display portion 40 at the center thereof, and have a predetermined interval around the center thereof. 6 day display scales 34 arranged from Monday to Saturday, 12 day display scales 31 arranged at regular intervals around the periphery of the day display scales 34, and a time display scale 60 minute division scales 32, divided into 12 azimuths around the periphery of the field 31 so as to form five layers for each bearing, to be easily distinguished by 5 minute units, and to represent 60 minutes in total Sixty second marking scales 33 are arranged at regular intervals to represent seconds around the perimeter of the scales 32.

The day display scales 34 and the time display scales 31, 32, and 33 are constituted by the liquid crystal display panel 100 illustrated in FIGS. 3 to 5 to show the current time according to the all-light display state of each scale. Unlike the hour or second display scales 31 and 33, the minute display scales 32 are divided into 12 azimuths and display five minutes for each direction. More easily, it has a boundary of 10 minutes or 2 directions.

On the other hand, in the method of displaying the current time by using each of the scales, the number of the pixel portion 107 driven by the liquid crystal display panel 100 is reduced when the entire scale is not displayed progressively, and only the corresponding scales are fully displayed. This will consume relatively much less power.

In other words, in order to reduce power consumption and minimize battery consumption, the active time (eg, work time, etc.) in which the user is active is displayed progressively in accordance with the current time, but the inactive time (eg, when the user is not active) , Returning time, rest time, etc.) can be displayed only the current scale directly, that is, the last scale is displayed directly, and the last scales are inactive (lighted out) to display only the current time.

Of course, in the non-inactivity time, only the last graduation, the corresponding graduation may be displayed. The selection for this operation is designed to be all controlled by the user's operation. In this case, the current time is displayed by displaying only the relevant scale. If necessary, the current time is operated by operating all the scales (ie, previous scales) including the scales. You can also display the whole light.

For example, in the case of displaying the present time of 7:14:53, the all-light display state is progressively all-in-one display 35a of the hour, minute, and second display scales 31, 32, and 33 to display the present time. Display. In addition, only one of the scales of the hour, minute, and second display scales 31, 32, and 33 may be fully-light-displayed, and the current time may be displayed through a combination of the fully-lighted scales.

FIG. 7 is an enlarged plan view of the segment display unit 40 shown in FIG. 6.

Referring to FIG. 7, the segment display unit 40 includes an AM / PM identification unit 41, a timer setting identification unit 42, an alarm setting identification unit 43, a scheduled date / scheduled time setting identification unit 44, and a remaining day. The remaining time identifying 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. Of course, this is also driven by the liquid crystal display panel 100.

The display of the identification sections 41, 42, 43, 44, 45, 46, 47 or the display of the input status panel / time display 48 is set by the setting input buttons 10 shown in FIG. Or displayed by the controller. If the display of the identification units 41, 42, 43, 44, 45, 46, 47 has a color display, it may indicate that the mode is set, and the identification display mode is not set differently from the figure. ) May not appear on the segment display unit 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 input the OFF function setting. can do. For example, it is possible to set the state of the second display scales to OFF, and to adjust other functions or the display state to the OFF state. 6 and 7, only some of the identification units may be displayed on the segment display unit 40 according to a setting input like the segment display unit 40. Many functions that are not mentioned above, such as scheduled place input, may be displayed on the segment display unit 40.

8 is a plan view showing still another example of the all-optical scale display clock according to an embodiment of the present invention.

Referring to FIG. 8, for example, the all-light scale display clock 30c indicating the remaining time includes the same scales as the time display scales indicating the current time, that is, the hour, minute, and second display scales 31, 32, and 33. Display the same time. However, under the control of the controller, the advancing direction of the all-optical display state becomes opposite to the present time advancing. For example, the minute display divisions 32 may be displayed to be sequentially turned off from the outside to the inside 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 31, 32, and 33 corresponding to the remaining time may be sequentially blinked in the reverse direction of the current time progress direction according to the control information.

In the all-optical graduation indication clock 30d indicating the remaining days, the time display divisions indicating the current time are the graduations indicating the remaining months and the remaining days. That is, the time display scales 31 are changed to scales 31b indicating the remaining months, and the minute display scales 32 are changed to scales 32b indicating the remaining days. In this case, the existing super display scales 33 are in a blinking state, that is, the pixel unit is not driven. The scales 32b representing the remaining days are divided into six directions and consist of five layers, one layer per two scales within each orientation. Two scales on the same floor within the same direction allow all lights to be displayed or deactivated at the same time according to the change of the remaining days, and sequentially from outside to inside within each direction as the remaining days decrease according to the remaining time information. In this case, all light directions are displayed or deactivated, and the six directions are reduced by 5 days so that the current direction can be reversed.

Although not shown, the months and remaining days display scales 31b and 32b are not progressive but may be displayed in a state in which only the display scale corresponding to the corresponding month or day is illuminated, in which case the display of a plurality of remaining days is indicated. Will be possible. In the case of indicating the remaining days / remaining time, the minute display divisions are divided into six directions, so that the electric display or the non-operation is performed by two divisions for each floor within each direction. In addition, it may be easily distinguished from whether the present time is indicated by whether the identification unit 45 indicating the remaining date / remaining period confirmation state, for example, the display 45 of “RES”, is displayed on the segment display unit 40. Alternatively, when the current time displayed on the input status plate / time display panel 48 of the segment display unit 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.
