Abstract

Предоставлен драйвер истока, содержащий двунаправленный регистр сдвига и множество каналов передачи данных, каждый из которых включает в себя регистр данных и DAC и присоединен к двунаправленному регистру сдвига и TFT, а также предоставлено LCD-устройство. DAC совместно используется двумя соседними каналами передачи данных для изменения на противоположную полярности опорного напряжения согласно сигналу изменения полярности линии, принимаемому от тайминг-контроллера, для определения полярностей выходных напряжений двух соседних каналов передачи данных. Драйвер истока имеет небольшой размер и низкую стоимость.
