FPD95120 Datasheet | National Semiconductor

Description 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 drive 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 ining video to acmodate 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 (Lo SSI) 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 mand set is supported to set display modes and operating parameters. Customized register profiles associated with each mand are loaded from an on-chip EEPROM. Registers can also be directly accessed by using the Register Access Mode.
