ea dip122-5 page 3 specifications may be changed without prior notice. printing error reserved contrast adjustment contrast voltage for all displays of ea dip122-5 series is typ. -4v. that means that for 5v power supply an additional negative voltage of min. 4v is required. display modules for -20..+70c (-5hnled, -5nlw and -5nla) are equipped with an on-board temperature compensation. so there's no more need for contrast adjustment while operation anymore. furthermore these 3 displays are featured with a superfast stn/fstn liquid that allows fast resonse even at very low temperatures: typical response time at -20c is 2 seconds only. backlight driving the backlight requires a current source or an external resistor for current limit. please take care of derating for t a >+25c. u f for yellow/green backlight is 3.9~4.2v, 2.2~2.6v (amber) and 3.0~3.6v for white led backlight. note: do never drive backlight direct to 5v; immediately damage my happen ! yellow/green - blue - amber the blue-white display ea dip122b-5nlw is best for indoor use with and without ambient light. reading the display requires a minimum of backlight with about 15ma. the yellow/green version ea dip122-5nled is especially designed for 24-hour or outdoor applications. these displays do provide best contrast for all ambient illuminations, even with direct sunlight. no need to say that these display can be read in darkness when led backlight is switched on. this is same for the amber backlighted version ea dip122j-5nla.
