Description

[Detailed Description of the Invention] This invention relates to a calendar display device.

Conventionally, a so-called perpetual calendar display device using a liquid crystal or the like has been devised.

An example of a conventional example is the one shown in Figure 1, which requires only 7 columns in width, but the display is as shown in Figure 2, where Sunday is not always on the left edge. However, there was a drawback that the display was difficult to read.

To give another conventional example, dates are arranged in 13 columns as shown in Figure 3, and Sunday's Su is displayed above the 7th column on the left.
, select the necessary Su display and date numbers, and display the calendar, for example as shown in Figure 4. In this case, Sunday is always on the left edge, but since the date numbers are arranged in 13 columns, the display position is unavoidably shifted to the left or right, resulting in poor display area efficiency and poor visual display balance. There were flaws.

In addition, attempts have been made to solve these drawbacks by providing a display with Sunday on the left edge, a not too large number of columns, good display area efficiency, and good display balance, but these problems can be solved with a single display layer. When I tried to create something that solved the problem, the date numbers had to become smaller and harder to read.

This invention solves these drawbacks in the prior art.

Next, an example of this invention will be described.

5A and 5B respectively show display layers 1 and 2 of the calendar display device of the present invention. Figure 5A
On the display layer 1, two series of date numerals are arranged in eight columns, and marks from SUN to SAT indicating the days of the week are arranged in two rows above. As these display elements, liquid crystal, electrochromic, etc. are used. In the display layer 2 of FIG. 5B, other two
Series date numbers are arranged in 8 columns. The two display layers 1 and 2 are provided one on top of the other as shown in the sixth figure. Let's take a look at the lead wires of these display layers. In the display layer 1, the display electrodes for the date numerals located in the leftmost column and the day of the week display mark in the lower row are S
11, and the second column is connected in S12, and so on, and the date numerals in the eighth column at the right end and the display segment of the day of the week display mark in the upper row are connected in S18. Regarding common electrodes, day of the week display marks are connected by C1, date numerals from 1 to 28 are connected by C2 and C3 for each series, and 29, 30, and 31 are connected by each series. They are connected separately by C4 and C5. Regarding the display layer 2, the display electrodes are s21 and s21 for each column.
Similar to the display layer 1, the common electrodes 1 to 28 are connected by C6 and C7, and the common electrodes 29, 30, and 31 are connected by C8 and C9, respectively. Furthermore, in the display layers 1 and 2, s
Connect 11 and s21, s12 and s22, sequentially, and s
By connecting 18 to s28, the number of terminals of the display segment can be reduced to 8, and driving can be performed with a total of 17 terminals including common.

7A and 7B are other embodiments, but the date arrangement in this embodiment is basically the same as that in FIGS. 5A and 5B. In this example, 2
When digit date numbers are placed side by side in the same display area as date numbers from other series, the date numbers from other series are arranged between the two digits to make the numbers easier to see. .

According to the calendar display device of the present invention having the above-described configuration, the display position is less likely to shift from side to side, and the display area efficiency and display balance are good.
