Yes. See Page 3 of the datasheet:What voltages do the backlight take on the BG Micro LCD1030 display? It doesn't say on the data sheet? Will 5v at the + and 0v at the - work?

As you can see, 4.6V is typical and 5V is maximum for the backlight LED. Limit current to around 470ma.
I have a few of these displays. There's an **broken link removed** from when I first learned to use one. Page 3 has a schematic. I see I put a pot on the backlight so I could adjust the intensity.
