Pin identification for a salvaged LCD
They seem pretty self-explanatory. Data, sclk and cs are normal SPI MOSI, CLK and CS. A0 is probably equivalent to C/D. RES is reset - tie high to run. Power and ground are obvious. The others look related to the back light.

However... How are you going to operate it? Do you know the SPI instructions to send? They will be specific to the display, so without a datasheet you're pretty much stuffed.
