Abstract

PURPOSE:To reduce the power consumption for display operation by providing a line transmission/reception control circuit, a character display control circuit, a display driver circuit, a character display board circuit, a timer circuit, a comparing circuit, a brightness adjustment control circuit, a manual switch circuit and a storage circuit. CONSTITUTION:The line transmission/reception control circuit 2 receives display information, the manual switch 9 and stored circuit 10 are used to register the change time when a display mode is changed, and the timer circuit 6 outputs current time information. The comparator 7 and brightness adjustment control circuit 8 outputs a change indication signal for the display mode when the current time from the timer circuit 6 coincides with the registered change time. A display driver circuit 4 receives the change indication signal and displays display information on the character display board circuit 5 in the display mode corresponding to the change indication. Consequently, it is judged automatically whether or not a market information display is currently required and the display mode of a decrease in display brightness, a display stop, etc., can be changed according to the judgement result, so the power consumption for the display can be reduced.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a display terminal device, and particularly to a display terminal device that performs efficient display by changing the display mode depending on the time of day.

(Prior Art) Conventionally, for example, market information from the trading market for products and securities sent via communication lines is displayed in a fixed format on a character display board as a display terminal device, and market trends are often displayed on a character display board as a display terminal device. It is made known to the people of

In a conventional display terminal device of this kind, a transmission/reception control circuit receives market information sent via a line 5, forms a character pattern based on this information, and displays the characters.

(Problems to be Solved by the Invention) The conventional display terminal device described above always displays, for example, market information on the character display panel at a constant brightness during the power-on period of the terminal device. Therefore, in conventional devices, periods when there is little need for display, such as times when market transactions are not conducted, are displayed in the same way as periods when market transactions are conducted and display is highly necessary. The disadvantage is that it consumes extra power.

(Means for Solving the Problems) A display terminal device according to the present invention includes means for receiving display information, a registration means for registering a change time for changing a display mode, a clock means for outputting current time information, and a clock means for outputting current time information. control means for outputting a display mode change instruction signal when the current time from the clock means matches the registered change time; and a control means that receives the change instruction signal and displays the display information in a display mode corresponding to the change instruction. and display driver means for displaying information on the display unit.

(Example) Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a configuration block diagram showing one embodiment of a display terminal device according to the present invention. This embodiment displays market information sent via a communication line from a trading market for products, securities, etc. in characters. For example, see Norano.

Display terminal device (market status display terminal device) 1 in this embodiment
The circuit includes a line transmission/reception control circuit 2, a character display control circuit 3, a display driver circuit 4, a character display board circuit 5, a clock circuit 6 for controlling the display mode, a comparison circuit 7, a brightness adjustment control circuit 8, and a manual switch circuit 9. , and a memory circuit 10.

This display terminal device 1 receives a line signal S1 for market information communication with the market side, and controls the line transmission and reception operations by a line transmission and reception control circuit 2.

The character display control circuit 3 receives market information via the line,
A character generation code signal S4 is output to the display driver circuit 4 in order to generate a display character code corresponding to this information and display it on the character display panel.

A received data signal S3 and a received data transfer permission signal S2 exist between the line transmission and reception control circuit 2 and the character display control circuit 3, and the former signal S3 notifies the line transmission and reception control circuit 2 of the presence of market information. The latter signal S2 causes the character display control circuit 3 to transfer the market information when new market information can be received, and notifies the line transmission/reception control circuit 2 of permission. The display driver circuit 4 supplies power to the display elements constituting the character display panel FI115, and controls lighting/extinguishing of the display elements in accordance with the display character code.

Next, changes in the display mode in this embodiment will be explained.

In this embodiment, the brightness level and display stop of the character display board are controlled by inputting a brightness adjustment control signal S5 to the display driver circuit 4 and making variable the power supply supplied to the display element. The display is stopped by supply suppression.

This change in the display mode involves lowering the brightness of the display panel and stopping the display in consideration of the market trading time, but this change is made by registering the change time in the device. Registration of the change time is performed by the manual switch circuit 9 and the memory circuit 10. That is, this is performed by the manual switch circuit 9 and the memory circuit 10. That is, by manual operation of the manual switch circuit 9, the manual switch instruction input signal S11 is supplied to the memory circuit 10, and the time and change details (
(intensity or weakness of brightness or display stoppage) is stored as data.

On the other hand, the current time is output by the time data signal S7 which is the output of the clock circuit 6, and the comparison circuit 7 compares the designated time (signal 38) stored in the storage circuit 10 with the current time (signal S7). A comparison is made to determine whether the specified time has been reached.

The brightness adjustment control port #I8 receives a time comparison output signal S9 from the comparison circuit 7 indicating that the specified time has been reached, and a brightness adjustment strength/weakness instruction which is the output of the memory port 810 and instructs either to increase or decrease the brightness or to stop the display. When receiving the signal 310, it generates and outputs a brightness adjustment control signal S5 indicating either normal brightness, low brightness, or display stop to the display driver circuit 4.

As a result, the display driver 4 can select the power to be supplied to the display element in three ways based on the character display element drive signal S6, and the display element can be lit with normal brightness, lit with low brightness, or display deduction points. state.

(Effects of the Invention) As explained above, the present invention can set the optimal display WIA depending on the time, for example, automatically determines whether or not it is necessary to display market information at the present time. Based on the determination result, it is possible to change the display mode such as lowering the display brightness or stopping the display, which has the effect of reducing power consumption for display.
