Why use a LED backlight with a LCD?When an LED backlight doesn;t work, it is a bgi issue. An LCD backlight is a solution to make a LCD readable when there is not enough outside light. The LED backlight is the most common type of backlight used in character, static and mono graphic displays and illuminates the LCD from the side or back of the display.20×4 Character LCD with LED Backlight (Parallel Interface , r with lcd backlightThis LCD includes a 25.5 resistance (two 51 resistors in parallel) in series with the backlight, so an external current-limiting resistor is not required for backlight supply voltages up to 5 V. For higher voltages, you should add a current-limiting resistor R LIMIT as shown above where: R LIMIT = (V BACKLIGHT 3.2V) / 0.072A 25.5OT: LCD backlight control | AVR FreaksMay 07, 2003 · LO on the base turns the backlight off, and HI turns it on. Use the Fast-PWM mode, and the COM21/COM20 bits set as 1:0. This sets (backlight on) OC2 at the start of the count, and clears it (backlight off) when the count reaches the value in OCR2. So if you set OCR2 to 16 the backlight will be on for 16 counts, and off for 240 counts, very dim.
