They can, of course be used on traditional 5 V systems. Unlike normal LCD modules, you order the display and the corresponding backlight separately. This gives you a wealth of possible combinations. Designed for compact hand-held devices, this modern LCD range provides a number of real benefits with or without backlight: * extremely compact at 55 x 31 mm at the standard font size of 5.57 mm (2 x 16) * ultra-flat at 2.0 mm without backlight or 5.8 mm including LED backlight * 4-bit, 8-bit and SPI interface (4-wire) * typical power consumption of only 250A in full operation (LED white backlight as of 3mA) * easy installation by simply soldering into the board * A whole range of design variants (63) can be supplied as of single units * Changing background color SETTING THE CONTRAST The contrast on all displays of the EA DOG series can be set with a command. This is done using bits C0 through C5 in the commandsContrast Se andPower/Icon Control/Contrast Se. Generally, the contrast is set once and kept constant across the entire operating temperature range (-20 through +70C) thanks to the integrated temperature compensation function. Even when run at 3.3 V, the displays do not require any additional negative voltage LED BACKLIGHTS Limiting resistor yellow/green Forwar Current 6 different variants are available for individual backlighting: EA LED55x31-G voltage max. 3,3 V 5 V white, yellow/green, blue, red, amber and full color. Connected in parallel 2,2 V 80 mA 14 ohm 35 ohm For monochrome backlights, 2 separate LED paths are Connected in series 4,4 V 40 mA - 15 ohm available, which can be switched in parallel or in series to Limiting resistor ideally match the system voltage. This means that all the white Forwar Current EA LED55x31-W voltage max. 3,3 V 5 V backlights can be run either at 5 V or at 3.3 V. Connected in parallel 3,2 V 60 mA 1,6 ohm 30 ohm Operation of the backlight requires an external series Connected in series 6,4 V 30 mA - - resistor for current limiting. This can be calculated from R=U/I you will find the values in the table. To improve life Limiting resistor blue Forwar Current time it is recommanded to use a current source only. EA LED55x31-B voltage max. 3,3 V 5 V Connected in parallel 3,2 V 60 mA 1,6 ohm 30 ohm The operating life of the yellow/green, red and amber Connected in series 6,4 V 30 mA - - backlights is 100,000 hours and that of the white and blue backlights much shorter. Limiting resistor amber Forwar Current Important: Never operate the backlight directly on a 5 V/ EA LED55x31-A voltage max. 3,3 V 5 V 3.3V supply, as this can immediately destroy the LEDs Connected in parallel 2,4 V 80 mA 11 ohm 32 ohm Connected in series 4,8 V 40 mA - 5 ohm INSTALLATION First, the display and the corresponding backlight are Limiting resistor red Forwar Current clipped together. The complete unit is then inserted into a EA LED55x31-R voltage max. 3,3 V 5 V PCB and soldered. Note that the 4 pins for the backlight Connected in parallel 2,1 V 80 mA 15 ohm 36 ohm must also be soldered from the top. Connected in series 4,2 V 40 mA - 20 ohm Important: There are one or two protective films on the Limiting resistor display (top and/or rear side) and one on each backlight. Full color Forwar Current EA LED55x31-RGB voltage max. 3,3 V 5 V Those have to be removed during or after production.
