Abstract

PURPOSE:To maximize the graphic display effect of a timer time while minimizing the number of liquid crystal display segments, by using seven display segments selected from a timer time graphic display segment group even in day display. CONSTITUTION:The reference signal outputted from an oscillator circuit A is supplied to a clock circuit C and a timer circuit D through a frequency divider B while the state of a manipulation switch G is read in a change-over control circuit H and either one of the output signals from the clock circuit C and the timer circuit D is selected in a display part E. In this case, the selected signal is optically displayed by a liquid crystal part F. In a usual time display state, the marks 21, 22 of a sec and a min are not displayed while a colon 23 is displayed and a date and a time are displayed by theta-shaped segments 13-20 and a day is displayed by segments 1-7. In addition, in a timer operation displayed state, the colon 23 and the segments 13, 14, 19, 20 are not displayed while the marks 21, 22 are displayed and a timer time is displayed by the segments 15-18.

Description

DETAILED DESCRIPTION OF THE INVENTION Conventionally, in the liquid crystal display section of a multi-function wristwatch, a display system has been adopted in which the Japanese character segment is also used as a font to provide many other functions. However, when displaying the remaining time until the timer ends in a bar graph or pie chart on a watch with a timer function, at least 5 to 10 display segments must be driven to create a graphic display that is satisfactory to the elderly. First, this has been a major problem in commercially available electronic circuits that have a limited number of liquid crystal display segments.

An object of the present invention is to provide a multifunctional wristwatch with a timer function, in which the graphic display effect of one hour of the timer is maximized and the number of liquid crystal display segments is minimized in the liquid crystal display section of the multifunctional wristwatch with a timer function.

For the above purpose, in the system of the present invention, the seven display segments of the timer one-hour graphic display segment group are also used to display the day of the week, and in order to enhance the impression of the passage of time, 10 minutes ago.

The display is set to 6 levels, from 1 minute ago to 4 seconds ago.

The following is an explanation based on actual cases.

FIG. 1 is a block diagram of a wristwatch with a timer function according to the present invention. A is an oscillation circuit that includes a crystal oscillator, B is a frequency dividing circuit, C is a clock circuit that measures hours, minutes, seconds, week, month, and day, D is a timer circuit that includes a down counter, and E is a decoder and drive circuit. , F is a liquid crystal display section, G is a display circuit including
The reference signal generated by the switching timer is divided into a required frequency by the frequency divider B, and is input to the clock circuit C and the timer circuit D. On the other hand, the states of the operation switches and switches of G are read into the switching control circuit of H, and the output signal of the clock circuit of C or the timer circuit of D is selected on the display section of E. The selected signal is optically displayed on the liquid crystal display section F.

FIG. 2 is a diagram showing the display form on the display section of the timer wristwatch. In the figure, 26 is a day mark printed on a parting plate outside the liquid crystal panel in order to make it easy for the user to see the entire position of the day display;
25 is a display segment of the liquid crystal display panel. -1
:(a) represents the all-on display state, (b) represents the normal time display state, and (tsu)1 represents the timer field crop display state.

In (A), the second mark 21 and the minute mark 22 are not displayed, and the colon 23 is not displayed.
The date and time are fully displayed from 5 to 20. The display segments 1 to 7 display the day of the month. (In the actual example, 12:34:59 is displayed on Monday 26th.) In (tsu), colon 26 and day segment 13 are displayed.
．． i4, 19.20 are not displayed, the second mark 21 and the minute mark 22 are displayed, and the timer one hour is displayed by the day-shaped segments 15 to 18. (In the example, 10 minutes and 8 seconds is displayed.) The one hour timer is subtracted and displayed every second by the start operation after initial setting. Display segments 1 to 12 perform a north graphic display corresponding to the displayed timer hour. The above graphical representation is shown in Table 1.

Table 1 continued on the next page; In the above embodiment, the position of the day of the week display is indicated by a Friday mark on the partition board, but the present invention is not limited to this in any way; for example, the day of the week is indicated on the liquid crystal display panel. There are also watches with the mark printed on them, or watches that do not display the position of the day mark on the liquid crystal display panel or on the parting board.As explained above, there are multifunctional watches that have a timer function with a graph ink display. , the normal day of the week display segment is also used as a graphic display of the timer hour when the timer is activated, and the display speed is set to 10 minutes ago, 1 minute ago, 4 minutes ago.
By setting the timer to three steps before the second, it is possible to give a strong impression of the passage of time as the timer approaches its end with a small number of liquid crystal display segments.

This has the advantage of making it possible to reduce the size of circuits and reduce costs.
