So it is very necessary to develop our own technology of cantactless ic cards and driver ic of read / write device 這就要求我們能夠自主開發(fā)射頻識(shí)別系統(tǒng)讀寫器的專用芯片。
4 , a solution of realization of driver ic in read / write device is presented and some test are also performed 4 、提出了一種射頻識(shí)別系統(tǒng)讀寫器driver的解決方案,并進(jìn)行了初步的調(diào)試和驗(yàn)證。
It has better output current accurate than normal 8 - channel - led driver ic with constant current , more output channels and better output current regulate accurate 它相比以往常用的8通道led恒流驅(qū)動(dòng)器,具有更強(qiáng)的多通道驅(qū)動(dòng)能力、更優(yōu)的輸出電流調(diào)節(jié)精度以及更高的電流匹配精度。
2 . 83 inch tft lcm , which works in de transfer mode , was designed . the tft lcm including 3 driver ic chips , hd66783 1 as gate driver , hd66779 2 as source driver , has 262k colors depth , 240 ( rgb ) 320 dots pixels 本課題基于tftlcm的驅(qū)動(dòng)原理,設(shè)計(jì)了一款2 . 83inchtftlcm模組,并對(duì)其模組設(shè)計(jì)、測(cè)試方案進(jìn)行了研究。
