Abstract

PURPOSE:To indicate hundredth digit in a channel display by a colon and a segment on the straight line thereof by forming a colon between second and third ones of four numerical display sections arranged sideways while another segment is formed on the straight running through the colon. CONSTITUTION:Four numerical display sections 141-144 each having seven segments 13 arranged in a shape of squarish 8 are formed on a liquid display plate 12 and dot-like segments 15 and 15' each forming a colon is formed between the display sections 142 and 143 while segments 16, 16' and 16'' are formed above the segments 15, below the segment 15' and between both the segments. When the segments 15 and 15' and 16, 16' and 16'' all come on, they are recognized as 1. Thus, even when the number of channels is a hundredth digit at the time of indicating channels, display can be done in the same size as the conventional time and channel display unit.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a novel time and channel display device and a time and channel display method, in particular, a numerical display section in which seven display segments are arranged in a sun-shape, arranged horizontally in four digits: The present invention relates to a display method and display device for displaying time and channels by arranging a pair of dotted segments i forming a colon separating hours and minutes in the center, and 100 It is an object of the present invention to provide a display method and a display device capable of displaying numbers, and even numbers in the 200s.

Background Art and Problems There is a demand for remote controllers for television receivers to display the current time and channel, and remote controllers designed to meet this demand have been developed. Since the size of the display device that can be attached to such a remote controller is limited, one display section is used to display the time at certain times and to display the channel at other times. FIG. 1(A) shows the display section of such a display device when displaying the time, and FIG. 1(B) shows the display section when displaying the channel.

Segments that are visible are shown filled in, and segments that are hidden are shown only as outlines.

In the figure, a is a horizontally long liquid crystal display board, b, b,...
is a display segment, and the seven display segments l-b, b
, . . . are arranged in a Japanese character shape, a one-digit numerical display section C is constructed. Each display segment b, b, 11
Fist・(±When it is not displayed, it is not visible, and when it is displayed, it becomes dark blue, and the numerical display parts of each digit are c, c,
By selectively displaying display segments b, b, ... of c, c, any numerical value from "0" to "9" can be displayed. As shown, when displaying the channel, "CH" can also be displayed using the upper first digit and upper second digit numerical display parts c and c.

d and d' are the second digit number display part C and the third digit number 11
A is a dot-shaped segment arranged between the display part C and is vertically spaced apart to form a colon e. f is a segment i arranged on the left side of the numerical display section C in the first digit from the top, and represents the morning by the display rAMJ. g is a segment placed below segment I.f, which is indicated as rAMJ, and indicates the afternoon with the expression r p M J.

By the way, such a remote controller has no problem if the channel number is only two digits, but it cannot display channels with three digit numbers. That is, in the United States, with the development and spread of CATV, the number of broadcasting stations has increased dramatically, and channels in the 100's are now appearing. Therefore, for the United States, the display device of the remote controller for television receivers must be capable of displaying channels in the 100s. Also, in Japan, CATV will develop and spread in the future, and there is a good possibility that the number of broadcasting stations will increase, so there is a need to be able to display channels in the 100 range even for domestic use. . Therefore, it is conceivable to make the digits below the colon e three digits instead of two, but increasing the number of digits in this way would require making the display section larger. This is not preferable because the size of the remote controller is limited as described above.

Therefore, as shown in Figure 2, segments h and h' for displaying rlJ are placed between the colon e and the numerical display section C of the second digit from the bottom, and when channels in the 100s are displayed. An attempt was made to bring its segments h, h' into the display state. However, in this case, the interval between the hundreds digit and the tens digit becomes shorter than the interval between the tens digit and the - digit. A problem arises in that the image becomes uneven and difficult to see.

Purpose of the Invention The present invention has been made in order to solve the above-mentioned problems. The purpose is to

Structure of the Invention The display device of the present invention that achieves the above object has four numerical display sections arranged in the horizontal direction in which seven segments are arranged in the shape of a "day", and the second numerical display section and the second numerical display section. A display device for displaying the time or channel by arranging a pair of dot-like segments forming a colon separating hours and minutes between the third numeric display part, the pair forming a colon Another segment is formed on a straight line passing through the dot-like segments of This feature is characterized in that the segments i and 2 formed on one straight line are displayed.

Further, in the first display method of the present invention, four numerical display sections each having seven segments arranged in a "mouth" shape are arranged in the horizontal direction, and the second numerical display section and the second numerical display section are arranged horizontally. The time and channel are displayed by means of a "display device" in which a pair of dot-shaped segments forming a colon separating the hours and minutes are arranged between the third numeric display section and the time and channel display method. The present invention is characterized in that when the number of the channel to be displayed is less than 200 and greater than or equal to 100, a pair of dot-shaped segments forming the colon are displayed.

In the second display method of the present invention, four numerical display sections each having seven segments arranged in the shape of a "day" are arranged in the horizontal direction, and the second numerical display section and the This is a time and channel display method in which the time is displayed and the channel is displayed using a display device in which a pair of dot-like segments forming a colon indicating hours and minutes are arranged between a third numerical display section and a third numerical display section. When displaying a channel, if the number of the channel to be displayed is less than 200 and greater than or equal to 100, one of the pair of dot-like segments forming the colon is set to the display state, and the number of channels to be displayed is 30.
When the number is less than 0 and 200 or more, the two segments forming the colon are both displayed.

Real Ai+! EXAMPLE Below, the time and channel display device and time and channel display method of the present invention will be explained in detail according to an embodiment shown in the attached drawings.

FIGS. 3 to 5 are for explaining an example of the method of displaying time and channels in the time and channel display section of the present invention. In this embodiment, the present invention is applied to a remote controller for remotely controlling a television receiver, and FIG. 3 is a circuit block diagram schematically showing the configuration of the remote controller. In the drawing, l is a key matrix circuit consisting of keys for remote control, and a television receiver (not shown) can be controlled by appropriately operating the keys constituting this key matrix circuit l. . 2 is a mode switching circuit which, when a key operation to designate a mode is performed, switches the mode according to the operation content; the mode of the remote controller is a current time display mode in which the current time is displayed on the display unit 3; , a reserved time display mode that is realized when you make a reservation so that the television receiver is automatically turned on and tuned to the specified channel when the specified time is reached, and a reserved time display mode that is realized for a certain period of time after the channel switching operation. There is a switching channel display mode. 4 is a timer that stores the reserved time (designated time) when the aforementioned reservation is made; 5 is a channel memory that also stores the reserved channel; 6 is a clock; and 7 is the memory contents of the timer 4 and the time ticked by the clock 6. This is a coincidence detection circuit that generates a coincidence signal when there is a coincidence. When an operation for making a reservation is performed, the reservation time is stored in the timer 4 and the reserved channel is stored in the channel memory 5.
When the time on the clock 6 coincides with the scheduled time on the timer 4, a coincidence signal is sent from the coincidence detection circuit 7 to the control signal transmission circuit 8.

The transmitting circuit 8 generates a remote control signal, and when a key operation such as channel switching or power-on is performed, the signal from the key matrix circuit 1 is output, and when a matching signal is output from the output circuit 1, the signal is output from the power source. The input signal and the signal indicating the channel stored in the channel memory 5 are respectively modulated and sent out. Reference numeral 9 denotes a light emitting diode connected to the output side of the transmitting circuit 8, which converts the output signal of the transmitting circuit 8 into infrared light.

IO is a decoder that receives signals from the key matrix circuit 1, clock 6, and mode switching circuit 2, and sends a signal to the display section 3 to display a display corresponding to the received signals.

When the display section 3 receives a signal from the decoder 10, it displays contents corresponding to the signal. And the decoder lO

Any numerical value from to r9J can be displayed,
In addition, "C" and rHJ can also be displayed. There are four numerical display sections 14 in the horizontal direction (141, 14
2, 143, 144), and the fourth digit 144 counting from the lower digits and the fourth digit 143 counting from C will display "C" and rHJ when the channel is displayed. 15.15' is the dotted segment I that makes up the colon.
・It is arranged between the numerical value display section 142 of the second digit from the bottom and the numerical value display section 143 of the third digit from the bottom. This colon consisting of segments 15.15'' is displayed when the time is displayed and serves the function of separating hours and minutes.

16.16', 16'' are segments arranged above the segment 15, between the segments 15 and 15', and below the segment 15'.
'' and segments 15.15' are arranged on a straight line extending in the vertical direction, and when all these segments 16, 15.16', 15', and 16'' are displayed, they can be visually recognized as rlJ. It is like that.

17 is a segment formed to draw rAMJ, which means morning, and 18 is a segment formed to draw "PM", which means afternoon.

Figure 5 is a circuit diagram showing only the part that drives 15.15', 16.16', and 16''.18 is an OR circuit, one input terminal receives the time display mode signal, and the other input terminal It receives a 100 channel signal, and its output terminal is connected to segments 15 and 15' forming the colon.Segments 16, 16' and 16'' are adapted to receive a 100 channel 4ij signal. The time display mode signal is a signal that becomes "high" when the time is displayed, and the lOO channel signal is a signal that becomes "high" when the time is displayed.
This signal becomes "high" when the channel is in the 0 range, that is, the 100th to 199th channels.

When this display device iJ, l l is in the time display mode, either segment 17 or 18 is in the display state to indicate morning or afternoon, as in the conventional case.
What IN by 748144.143? is displayed. Also, segments 15 and 15' forming the colon
becomes the display state, and the numerical display tjRl 42.
141, the minute is displayed.

In addition, in the channel display mode, the numerical display section 144 indicates "C" and the numerical display section 143 does not indicate rHJ. And the number of channels displayed is 100.
If the segment is less than 15.15', 16.16',
16" is hidden, and the numerical display part 142.141
The 2-digit Nayannel will be displayed.

By the way, when the displayed channel is in the 100s, segments 15.15', 16.16', and 16'' receive the 100 channel signal directly or via the OR circuit 18 and enter the display state, and the "l" is displayed. indicate. The numerical display section 142 displays the tens digit of the channel, and the numerical display section 141 displays the negative digit of the channel. FIG. 4 shows the display unit 3 in a state where channels in the 100s (%i1.33 channels) are displayed.

Thus, the segments 15.15' that make up the colon
Since it is made to form a part of "1" representing a channel in the 100s, it is possible to display channels in the 100s without enlarging the display section 3.

Furthermore, there is no risk that the spacing between the three-digit numbers indicating channels will become unbalanced as in the conventional system shown in FIG. Therefore, the display will not become difficult to see.

Other Embodiments FIGS. 6(A) and 6(B) are for explaining different embodiments of the wood engraving and channel display method. In each embodiment, the structure of the segments of the display section 3 is completely different from the conventional one (shown in FIG. 1), and corresponds to segments 16, 16', 16'' of the display section 3 shown in FIG. There isn't.

In the embodiment shown in FIG. 6(A), the segments 15 and 15' forming the colon are
It is connected to the output terminal of the OR circuit 19 which receives the No. 4 and No. 100 channel signals.

Therefore, the segments 15 and 15' forming the colon serve to separate hours and minutes when in time display mode.
In the channel display mode, the hundreds digit functions to indicate rlJ only when the channel is in the 100s.

Further, the embodiment shown in No. 61N(B) is capable of displaying channels in the 200s.

In the figure, 20 is an OR circuit that receives the time display mode signal and the 2OO channel signal, 21 is an OR circuit that receives the time display mode signal, the 100 channel signal, and the 200 channel signal, and the output terminal of the OR circuit 20 is the segment 15, and the output terminal of the OR circuit 21 is connected to the segment 15'.

For a 100 channel signal, the hundreds digit of the channel is rl
In line with the signal that becomes "high" when it is J, 2
For 00 channel signals, the hundreds digit of the channel is "2"
When this is the case, the signal becomes "/\i".

Therefore, if the channel to be displayed is in the 100s, the lower segment 15' of 15 and 15' forming the colon will be displayed, and if the channel to be displayed is in the 200s, the segment 15' forming the colon will be displayed. Item 15.1
If the number of channels to be displayed is less than 100, both segments 15 and 15' are in the non-display state. Therefore, segment 15.15
' can also display channels in the 200s. Therefore, even if the number of channels exceeds 200 in the future, it can be handled.

Effects of the Invention As described above, according to the present invention, the display area can be displayed without increasing the size and without making it difficult to see.
It is possible to display the channel number. Also, especially
By displaying one of the two segments that make up the colon, it is shown that the hundreds digit is "1", and by displaying both segments, the hundreds digit is "1". 2", it becomes possible to display channels from 1 to 299.
