TIME SERIES DRIVER FOR LIQUID CRYSTAL DISPLAY

摘要

A time series driver for liquid crystal display, which comprises: a primary time series control chip (21), a secondary time series control chip (22), a display driver interface (10), a backlight driver interface (40), a first memory (31), a second memory (32), and a data input interface (60). The display driver interface (10) is used to electrically connect with a liquid crystal panel (50), the backlight driver interface (40) is used to electrically connect with a backlight driver circuit. The primary and secondary time series control chips (21, 22) receive a control signal from the data input interface (60) and output a display time series control signal and a display data signal from the display driver interface (10) to the liquid crystal panel (50) based on the control signal, and the secondary time series control chip (22) outputs a pulse width modulation signal from the backlight driver interface (40) to the backlight driver circuit. The time series driver for liquid crystal display adopts only two time series control chips to drive the liquid crystal panel and a backlight source and saves a control chip that needs to be added during backlight scanning in the existing technology, which reduces the cost.
