the fpd95120 is a 320–channel ltps/cgs driver with partial display memory, a 24–bit rgb video interface and enhanced display quality. it provides 320 output source drivers with a 1:3 glass multiplex ratio. it includes a 230,400–bit memory for partial display modes, a timing controller with glass interface level-shifters, ac and dc v_comdrive schemes and glass power supply circuits. the output format can be configured to drive arbitrary display resolutions up to 320rgb columns. advanced processing features enable up-scaling of incoming video to accommodate legacy graphics. there is also an upscale function for the partial display window to enable larger window sizes.

the on-chip partial display memory is configurable in window size, location and color depth. this memory can support partial display windows such as 240x320 in 3–bit mode and 320x720 in 1–bit color mode. the partial display memory can be used to self-refresh a region of the display in a reduced power state or as an overlay for osd and alpha-blending features. the fpd95120 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 (lossi) is provided to control display operating modes and provide 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 each command are loaded from an on-chip eeprom. registers can also be directly accessed by using the register access mode.
