! Plasma Sub Field Drive Recap: The 3 phases for firing pixels are given below and is called a SUBFIELD: INTIALISE ---- ADDRESS (SCAN) ---- SUSTAIN These steps create light from pixels. 3-1. Sub Field 3-1. Sub Field Purpose: Control Each Pixel's Brightness Individually (Set up) (Scan & Write) (Emission) Initialize Address Sustain Address Sustain Period Period One Sub Field 1 Initialise phase resets all pixels 2 Scan phase writes WALL VOLTAGE to all pixels on a line by line basis 3 Sustain phase drives the entire screen to produce brightness from the pixels that have wall voltages loaded. 1 !
