Custom Controller ASIC Designed for OMNIVISION LCOS Panels
The OVP921 companion chip is a custom controller ASIC designed to drive OMNIVISION’s single panel, color field sequential LCOS panels. The OVP921 provides enhanced system performance without the need for an external image processor.
The OVP921 integrates a host of features that simplify system design, while saving both space and power. The OVP921 has built-in keystone correction, frame rate conversion, video input scaling, an LED controller, and an embedded 8051 microcontroller (MCU).
The OVP921 can accept inputs via 24‑bit RGB, MIPI or USB.
OVP921 will drive OMNIVISION’s color field sequential LCOS panels with resolutions up to 1280 x 720
Includes two video inputs:
– Single pixel 24-bit RGB
– 2 channel MIPI DSI receiver 24-bit packed RGB888
Includes dual internal PLL clock generation
Outputs enable/disable control signals to external solid state light sources
Supports horizontal and vertical flipping and programmable sync polarities
Supports several video scaling functions
Converts incoming video to fixed resolution of LCOS panel
±15 degree vertical keystone correction
Includes on-chip 8051 microcontroller with 32 KB program space and 256 bytes RAM
