FPD95220
320-Channel LTPS Dot Inversion Driver with
Programmable Partial Display
General Description
The FPD95220 is a 320–channel LTPS dot inversion driver
with Partial Display Memory, and an 18–bit RGB video inter-
face. It provides 320 output source drivers with a 1:3 glass
multiplex ratio. It includes a 77,112–bit memory for partial
display modes, a timing controller with glass interface level-
shifters, a DC VCOM driver and glass power supply circuits.
The output format can be configured to drive arbitrary display
resolutions up to 320 RGB columns.
The on-chip Partial Display Memory is configurable in window
size, location and color depth. This memory can be used to
self-refresh a region of the display in a reduced power state.
The FPD95220 device also includes independent RGB gam-
ma curve adjustments as well as user-definable color palettes
for 1–bit and 3–bit Partial Display modes.
A low-speed serial interface controls display operating modes
and provides access to the Partial Display Memory. This in-
terface can support both 8–bit and 9–bit protocols. A standard
command set is supported to set display modes and operating
parameters. Customized register profiles associated with
commands are loaded from an on-chip EEPROM. Registers
can also be directly accessed by using the Register Access
Mode.
