2. Description of the Related Art A display device used in this type of riding behavior measuring device includes a transparent substrate which is disposed opposite to each other, a liquid crystal which is enclosed between the transparent substrates to form a display region, and a plurality of segments formed on the transparent substrate. It was configured by disposing divided electrodes.

[0003]

In the above-mentioned prior art, a liquid crystal display device which is a low power consumption display device is used as the display means in order to keep the power consumption of the device low. Since the data displayed by driving was extremely poor in visibility, it is necessary to determine whether the displayed data has reached the set value, that is, whether the optimal reproduction period has been reached. However, there is a drawback in that the administrator needs to carefully read and confirm in close proximity to the display device, which is troublesome. An object of the present invention is to eliminate the above-mentioned conventional drawbacks.

[0004]

In order to achieve this object, the liquid crystal display device according to the present invention is characterized in that a transparent substrate which is opposed to the transparent substrate and a liquid crystal which is enclosed between the transparent substrates to form a display region are provided. A first electrode covering the display area and a second electrode divided into a plurality of segments are arranged on the transparent substrate. The characteristic configuration of the boarding behavior measurement device is that the boarded animal is provided with a switch means operated by the boarding behavior, a measurement means for measuring the operation time or the number of times of operation of the switch means, and a measurement result by the measurement means. It is a boarding behavior measurement device configured by attaching display means for outputting and power supply means for supplying power to them, wherein the liquid crystal display device is used for the display means. is there. The display means is provided with display control means for driving the second electrode when the measurement result of the measuring means is less than a set value and driving the first electrode when the set value is reached. There is something.

[0005]

By driving the second electrode, necessary data can be displayed according to the segment electrode to be driven.
For example, if the second electrode is composed of a 7-segment electrode showing numerical data, data such as the number of times of boarding and riding can be displayed. By driving the first electrode, the entire display area can be switched between "bright" and "dark" for display, so that the visibility can be improved. For example, when the data such as the number of times of boarding has reached the set value, by making the whole "dark", it is possible to recognize that the set value is reached without reading the data.

[0006]

As described above, according to the present invention, it is possible to make a predetermined judgment while realizing the request for low power consumption while displaying the data at one time and reading the data at another time. It is now possible to provide a display device that can be manufactured at low cost.
