FPD95220 320-Channel LTPS Dot Inversion Driver with Programmable Partial Display PRELIMINARY September 2007 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 interface. 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 levelshifters, 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 gamma 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 interface 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. Features ■ Dot Inversion ■ Reduced audible and electrical noise for touch...
