LC-DISPLAY SERIES EA W240-7K

These graphic displays provide a resolution of 240x128 dots. All of them are featured with high
contrast STN technology. 3 different backlights are available:
- EA W240-7KHLEDB is featured with yellow/green LED backlight. That means that displays do
have black characters on yellow/green illuminated background. Power consumption for
backlight is typ. 900mA at forward voltage of typ. 4.1V. A current limiting resistor i necessary in
any case (e.g. at 5V: R = (5V-4.1V) / 700mA = 1.3 Ω). Maximum current for backlight is 2000mA
(note: heavy heat will occur). Life time of LED backlight is 100,000 hours, operating
temperature range is -20..+70°C (built-in temperature compensation).
- EA W240-7KHC is featured with CFL backlight. That means that displays do have white
characters on blue background (negative mode). Operating the CFL backlight requires a CFL
inverter EA CXA-E005W. Power consumption for backlight is about 300mA@5V. Life time of
backlight depends on application with 10,000 up to 30,000 hours. Operating temperature range
is -20..+70°C (built-in temperature compensation).
- EA W240-7KHLW is also negative blue and is featured with a white LED backlight. This kind of
backlight requires a current source or limiting resistor for operation. Current consumption is with
max. 135mA (@25°C) and 3.0..3.6V extreme low. Operating temperature range is -20..+70°C,
featured with built-in temperature compensation. For temperatures above +25°C do not forget
to design in a derating for current.
BUILT-IN CONTROLLER T6963 C
All modules come with controller T 6963C. It is good for direct connection to 8 bit microprocessor
system and contains a comfortable command set. There is for example a character set already
built-in, which can be extended or redefined in complete. Each character can be attributed with
e.g. "invers", "blink" or "invisible".
Iin graphic mode on-board display RAM (32kB) provides up to 8 full-screen pages. Text and
graphic layer can be displays via "and-", "or-", "exor-" function..
CONNECTION
A 1-row pin header can be soldered into 2.54mm eyelet strip.
Touch Panel
All versions are availble with and without touch panel as a standard. Construction is a resistive
matrix type. It can be operated with blank finger
