396-CHANNEL DRIVER WITH SYSTEM-ON-CHIP (SOC)
FOR COLOR AMORPHOUS TFT LCD
1. GENERAL DESCRIPTION
The SPFD54124B, a 262144-color System-on-Chip (SoC) driver
LSI designed for small and medium sizes of TFT LCD display, is
capable of supporting up to 132xRGBx162 in resolution which can
be achieved by the designated RAM for graphic data.
396-channel source driver has true 6-bit resolution, which
generates 64 Gamma-corrected values by an internal D/A
converter.
The SPFD54124B is able to operate with low IO interface power
supply up to 1.6V and incorporate with several charge pumps to
generate various voltage levels that form an on-chip power
management system for gate driver and source driver.
The built-in timing controller in SPFD54124B can support several
interfaces for the diverse request of medium or small size portable
display. SPFD54124B provides system interfaces, which include
8-/9-/16-/18-bit parallel interfaces and serial interface (SPI), to
configure system. Not only can the system interfaces be used to
configure system, they can also access RAM at high speed for still
picture display. In addition, the SPFD54124B incorporates 6, 16,
and 18-bit RGB interfaces for picture movement display. The
SPFD54124B also supports a function to display eight colors and
a standby mode for power control consideration.
