    • A method of providing a Push-To-Talk (PTT) service is provided. In a PTT service provided through a PTT server to a PTT portable terminal, the PTT portable terminal requests termination of its participation in a PTT group call during the PTT group call takes place among at least three members, requests recording of the PTT group call to the PTT server, and ends a PTT application program. When the PTT group call is terminated among the remaining members, the PTT portable terminal receives from the PTT server a notification message indicating that the PTT group call has been recorded and plays the recorded PTT group call.
    • 提供了一种提供一键通(PTT)服务的方法。 在通过PTT服务器提供给PTT便携式终端的PTT服务中,PTT便携式终端在PTT组呼叫期间在至少三个成员之间请求终止参与PTT组呼叫,请求记录PTT组呼叫 PTT服务器,并结束PTT应用程序。 当PTT组呼叫在剩余成员中终止时,PTT便携式终端从PTT服务器接收到指示已经记录了PTT组呼叫的通知消息,并且播放记录的PTT组呼叫。

    • The present invention has been made in an effort to provide a circuit for generating driving voltages, a liquid crystal display, and a method of generating driving voltages having advantages that a plurality of driving voltages are not reduced so that desired grays are displayed and the contrast ratio is not deteriorated. For this purpose, driving voltages are generated using a battery voltage outputted from a battery of a mobile device according to an embodiment of the present invention. In this manner, by generating a source voltage VS and a common voltage Vcom using a battery voltage V_BAT, the reduced amounts of the source voltage VS and the common voltage Vcom are lessened, and therefore, voltages required by the specifications can be maintained. As a result, black is displayed more darkly or white is displayed more brightly, so that the contrast ratio C/R of a display device can be increased.
    • 本发明的目的在于提供一种用于产生驱动电压的电路,一种液晶显示器和一种产生驱动电压的方法,该驱动电压具有多个驱动电压不被降低以便显示所需的灰度和对比度 比例没有恶化。 为此,根据本发明的实施例,使用从移动设备的电池输出的电池电压产生驱动电压。 以这种方式,通过使用电池电压V_BAT产生源极电压VS和公共电压Vcom,减小源极电压VS和公共电压Vcom的量,因此可以保持规格所要求的电压。 结果,黑色显示得更暗,或者白色显示得更亮,从而可以提高显示装置的对比度比率C / R。
