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 36,0x27,5 mm at the standard font size of 2.6 mm (4 x 10) * ultra-flat at 2.0 mm without backlight or 4.6 mm including LED backlight * SPI interface (2-/3-/4-wire) and IC (2-wire) * typical power consumption of only 440A in full operation (LED white backlight as of 3mA) * easy installation by simply soldering into the board * A whole range of design variants can be supplied as of single units * Changing background color LED BACKLIGHTS 3 different variants are available for Limiting resistor individual backlighting: amber, yellow- amber Forward Current EA LED36x28-A voltage max. green/red, green/red/white. 3,3 V 5V For the amber backlight, 2 separate LED Connected in parallel 2,1 V 60 mA 20 ohm 48 ohm paths are available, which can be switched Connected in series 4,2 V 30 mA - 27 ohm in parallel or in series to ideally match the system voltage. This means that all the Limiting resistor backlights can be run either at 3.3 V and green/red/white Forward Current higher voltages. EA LED36X28-ERW voltage max. 3,3 V 5 V Operation of the backlight requires an green path 3,0V 45 mA 7 ohm 45 ohm external series resistor for current limiting. red path 2,1 V 45 mA 27 ohm 65 ohm This can be calculated by R=U/I you will white path 3,0 V 30 mA 10 ohm 67 ohm find the values in the table. To improve life time it is recommanded to use a current source only. Limiting resistor yellowgreen/red Forward Current EA LED36x28-GR voltage max. The operating life of the yellow/green, red 3,3 V 5V and amber backlights is 100,000 hours and red path (AGR/CR) 2,1 V 45 mA 27 ohm 65 ohm that of the white backlight is a bit shorter. yellowgreen path (AGR/CG) 2,1 V 60 mA 20 ohm 48 ohm Important: Never operate the backlight directly on a 5 V/3.3V supply, as this can immediately destroy the LEDs INSTALLATION First, the display and the corresponding backlight are clipped together. The complete unit is then inserted into a PCB and soldered. Note that the 4 pins for the backlight must also be soldered from the top with less tin. Important: There are one or two protective films on the display (top and/or rear side) and one on each backlight. Those have to be removed during or after production.
