MLA COLUMN (SEGMENT) DRIVER

SSD1871 is a member of MLA (Multi-Line Addressing) column driver family. SSD1871 has equipped with 160 five-level segment driving outputs. SSD1871 can be used together with MLA row drivers ⁽¹⁾ and MLA power chip ⁽²⁾ to form LCD display systems with high speed and good contrast display quality. Besides, the power consumption of an MLA display system is lower than that of a display system using conventional driving method.

SSD1871 has built in display RAM which enables the drivers to store display data and to generate LCD driving signals. The display data transmission from the controller can be suspended when there is no change in the display (Halt Write Function), thereby enabling a low power display system.
