I've just received a 7" SSD1963 based touch screen LCD from china 
It has a micro SD card slot and two 32 way connectors (both of which have the SAME connections):
GND 3v3
D1 D0
D3 D2
D5 D4
D7 D6
D9 D8
D11 D10
D13 D12
D15 D14
RS CS
RD WR
TE RST
INT TD0
PWM TD1
PCS TSCK
SDCS TCS
5V GND (But these two are not connected)
There is a diagram on the back of it that goes like this:
JP1 Back_Light
@ SSD-PWM
MCU-PWM
JP1 has a SMD resistor soldered across it at the factory and I think that "@ SSD-PWM" is telling me about this model.
Not a bad price for such a large touchscreen with card reader either........
.... now to connect it
