I use this screen C0240QGLI-T recently .I use FPGA and RGB+SPI interface to drive it.I use SPI created by FPGA to initialize,then i sent RGB data using RE0-RE4,GE0-GE5,BE0-BE4 to screen(parallelling). after i send SPI ,i make en=1,then the screen is white.But when i sent RGB to the screen, the screen is dark,i don't know why it is.whether there is some special command between the SPI and the RGB mode. is anyone can help me?thanks a lot.

Have you tried setting DISP_ON = 1?

I've just bought the same oled display from ebay, is it working good for you?
