Definition of optical data, see page 84 Applied to DB0-DB7, NotCS, E, R/W, RS Recommended LC driving voltage may fluctuate about +/- 0.5V by each module Background colour of the LCD changes depending on temperature. Between 40-50C optical characteristics of the LCD like contast and viewing angle change but the display remains readable. Storage at -20C < 48 hr.
