Printing and Page 2 typographical errors reserved. 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 ). 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..+70C (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..+70C (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 ( 25C) and 3.0..3.6V extreme low. Operating temperature range is -20..+70C, featured with built-in temperature compensation. For temperatures above +25C 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.inver,blin orinvisibl. Iin graphic mode on-board display RAM (32kB) provides up to 8 full-screen pages. Text and graphic layer can be displays viaand,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 Pin Symbol Function or stick. Surface is hardened and anti-reflex. 1 GND Ground Potential for logic (0V) resolution is 10x6 fields. Contrast adjustment 2 VDD Power supply for logic (+5V) Pin 17 is an output with its -16..-18V.
