GENERAL DESCRIPTION
The output format can be configured to drive arbitrary display resolutions up to 320 RGB x 480. 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 320x480 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 FPD95320 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 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.
