ea dog l 128-6 page 2 electronic assembly reserves the right to change specifications without prior notice. printing and typographical errors reserved. ea dog l 128 the ea dog l 128, a 128x64-pixel graphics display, is a new addition to electronic assembly?s ea dog l series. it, too, has pins that allow it to be mounted quickly and easily. 7 different optional led backlights are available. these can be combined with 5 different display technologies, making it possible to have up to around 20 different designs. designed for compact, handheld devices, this modern lcd series offers a number of benefits with and without backlighting: * extremely compact (68x51 mm) with a large viewing area of 64x36 mm * super-flat: 2.8 mm without backlight module, and only 6.5 mm with a b./l. module mounted * serial spi interface (4-wire) * single supply +3.0 v or +3.3 v or dual power supply +1.8..3.3v * typical power consumption of only 320a in full operation (white led backlight from 5ma) * easily mounted by soldering * wide range of design variants orderable as single units, backlighting color changes possible contrast adjustment the contrast can be set by means of a command for all the displays in the ea dog l series. the contrast setting of the display must be set once by the software, and is then kept constant throughout the entire operating temperature range (-20..+70c), thanks to the integrated temperature compensation. led backlight 7 different variants are available for individual backlighting: white, yellow/green, green, blue, red, amber and a full-color version. there are 3 separate led paths available for each monochrome backlight that can be switched in parallel or in series to suit the system voltage. this means that most backlights can be run at either 3.3 v or a higher voltage. to operate the backlight, we recommend a current source (e.g. cat4238td) or an external series resistor to limit the current. this can be calculated from r=u/i; you can find the values in the table on the right. to prolong the life of the backlights, we recommend that you use a current source. the operating life of the yellow/green, red and amber backlights is 100,000 hours. the life of the white and blue backlights is considerably shorter. we recommend that you dim these or switch them off whenever possible. important: never connect the backlight leds directly to a 5 v/3.3 v supply as this will immediately destroy the leds. al ways use a current source. please note that derating applies at temperatures exceeding +25c. assembling first, clip the display and backlight modules together by gently pushing the display pins through the corresponding holes on the backlight module. then insert the entire module into the socket, or into the soldering holes on the pcb. the backlight pins (the 2 rows with 3 pins at the bottom) must be soldered on the top side as well to ensure good contact between the modules. important: the display has 2 protective films on the top and the bottom (except the version dog l 128l that does have 1 foil on the top only), and there is also one on the backlight. these must be removed. make sure that neither display nor backlight will never come into contact with any kind of liquid like fluxer, cleaner, water. led backlight forward voltage (v) current max.
