液晶显示电话机与普通电话机相比,它还具有时钟、通话时间和拨号号码显示功能。平常挂机时它显示时钟;当摘机拨号时它显示所拨号码;号码拨完,开始计通话时间;挂机后,又回显时钟。本文以佳信HA238(Ⅷ)P/TSD型液显电话为例,介绍其原理及主要集成电路。该机采用HT—1610液晶显示接口电路,它与拨号集成电路HT—9115D配套使用,其中HT—1610接口电路已与液晶显示屏做成
LCD telephones have the clock, talk time, and dialing number display capabilities over regular phones. It shows the clock when it is on-hook; it displays the dialed number when it goes off-hook dialing; it dials and starts counting the call time; In this paper, good letter HA238 (Ⅷ) P / TSD-type liquid-crystal telephone, for example, describes the principle and the main integrated circuit. The machine uses HT-1610 LCD interface circuit, which is used in conjunction with the dial-up integrated circuit HT-9115D, HT-1610 interface circuit which has been made with the LCD screen
