It also has pins that allow it to be mounted quickly and easily. 6 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 (55x31 mm) with a large viewing area of 51x15 mm * Super-flat: 2.0 mm without backlight module, and only 5.8 mm with a b./l. module mounted * Serial SPI interface (4-wire) * Single supply +2.4 V or +3.3 V * Typical power consumption of only 140A 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 DOGM 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 Limiting resistor 6 different variants are available for individual backlighting: white, yellow/green Forward Current EA LED55x31-G voltage max. 3,3 V 5 V yellow/green, blue, red, amber and a full-color version. Connected in parallel 2,2 V 80 mA 14 ohm 35 ohm There are 2 separate LED paths available for each monochrome Connected in series 4,4 V 40 mA - 15 ohm 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 Limiting resistor white Forward Current 5 V. EA LED55x31-W voltage max. 3,3 V 5 V To operate the backlight, we recommend a current source (e.g. Connected in parallel 3,2 V 60 mA 1,6 ohm 30 ohm CAT4238TD) or an external series resistor to limit the current. This Connected in series 6,4 V 30 mA - - can be calculated from R=U/I you can find the values in the table on Limiting resistor the right. To prolong the life of the backlights, we recommend that you blue Forward Current EA LED55x31-B voltage max. 3,3 V 5 V use a current source. Connected in parallel 3,2 V 60 mA 1,6 ohm 30 ohm The operating life of the yellow/green, red and amber backlights is Connected in series 6,4 V 30 mA - - 100,000 hours. The life of the white and blue backlights is about 80,000 hours. Limiting resistor amber Forward Current EA LED55x31-A voltage max. 3,3 V 5 V Important: Never connect the backlight LEDs directly to a 5V/ Connected in parallel 2,4 V 80 mA 11 ohm 32 ohm 3.3V supply as this will immediately destroy the LEDs. Always Connected in series 4,8 V 40 mA - 5 ohm use a current source. Please note that derating applies at temperatures exceeding +25C. Limiting resistor red Forward Current EA LED55x31-R voltage max. 3,3 V 5 V ASSEMBLY Connected in parallel 2,1 V 80 mA 15 ohm 36 ohm First, clip the display and backlight modules together by gently pushing Connected in series 4,2 V 40 mA - 20 ohm the display pins through the corresponding holes on the backlight module. Dontt forget to remove the protection foil from display and Limiting resistor Full color Forward Current backlight before. Then insert the entire module into the socket or into EA LED55x31-RGB voltage max. 3,3 V 5 V the soldering holes on the pcb. The backlight pins (the 4 pins at the Connected in parallel 4V 125 mA - 3x24 ohm bottom side) must be soldered on the top side as well to ensure good contact between the modules. Important: The display has a protective film on the top and/or the bottom, 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. Page 2 Printing and typographical errors reserved.
