1. Introduction
2. Functional Description
1.1 LCD Controller Features
2.1 Overview
The LCD controller is required to control the power sequencing of the LCD panel. All
the other functions required for an LCD controller like color expansion, screen timing
generation is taken care by the QVCP (Quality Video Composition Processor). QVCP
also does some video enhancement functions. Please refer to the QVCP
documentation for the details about these functions.
The following feature allows PNX17xx Series to be connected to many LCD models:
The LCD controller receives the parallel video out data from the QVCP along with the
timing signals (HSYNC, VSYNC, CBLANK and CLK_LCD) and applies power
sequencing before sending it out to the LCD interface. It converts CBLANK signal into
