    • The communication terminal is comprised of: a voice input unit for inputting voice; a voice converting unit for converting the voice inputted into a voice signal; a character converting unit for converting the voice signal into a character signal; a transmitting unit capable of transmitting both the voice signal and the character signal via a communication line; and a control unit for controlling the transmitting unit in such a manner that the transmitting unit transmits the voice signal, or the character signal in response to a condition of the communication line. Also, the communication terminal is comprised of: a receiving unit capable of receiving both a voice signal and a character signal; an output unit for outputting the voice signal received by the receiving unit; and a display unit for displaying thereon the character signal received by the receiving unit.

    • A potential of a data signal line S during a scanning period is charged to a substantially intermediate potential of a data signal at a corresponding frame. Thus, extremely large dispersion does not occur in a potential of each pixel capacitor with respect to a potential of the data signal line S, so that it is possible to restrict dispersion of a leak current flowing via an active element of each pixel. Thus, potential variation of a pixel PIX is reduced, so that it is possible to improve display quality during a non-scanning period. That is, in an active-matrix-type liquid crystal display, when a frame frequency is reduced by setting the non-scanning period to be sufficiently larger than a scanning period while a standby image is being displayed so as to realize low power consumption, the display quality is improved.
    • 扫描周期期间的数据信号线S的电位被充电到相应帧的数据信号的大致中间电位。 因此,相对于数据信号线S的电位,每个像素电容器的电位不会发生极大的色散,从而可以限制流过每个像素的有源元件的漏电流的色散。 因此,像素PIX的电位变化减小,使得可以在非扫描期间提高显示质量。 也就是说,在有源矩阵型液晶显示器中,当通过在显示待机图像的同时将非扫描周期设置为比扫描周期充分大来降低帧频,从而实现低功耗, 显示质量得到提高。

    • Conventionally, no provision has been made to perform an update during a period of time during which the user does not use a communications terminal. Frequently used programs and data need be updated frequently, and infrequently used programs and data need not be frequently updated. Therefore, it is preferred that an update be performed depending on the frequency of use. No provision has been made heretofore to perform an update in accordance with frequency of use. To solve these problems, the communications terminal has a communication section for communicating with a server via a communication network, a storage section for storing a program, a control section for controlling the communication section and storage section, and a usage storage section for storing the usage status of the communications terminal, and a program stored in the storage section is updated in accordance with the usage status stored in the usage storage section.
    • 通常,在用户不使用通信终端的时间段期间,没有进行更新来进行更新。 经常使用的程序和数据需要频繁更新,不经常使用的程序和数据不需要频繁更新。 因此,优选根据使用频率进行更新。 迄今为止,根据使用频率不进行更新。 为了解决这些问题,通信终端具有用于经由通信网络与服务器通信的通信部,用于存储程序的存储部,用于控制通信部和存储部的控制部,以及用于存储 通信终端的使用状态和存储在存储部中的程序根据存储在使用存储部中的使用状态来更新。
