a-Si TFT LCD Single Chip Driver 480(RGB)x864 Resolution and 16.7M-color The ILI9806E is a 16.7M single-chip SOC driver for a-Si TFT liquid crystal display panels with a resolution up to 480(RGB)x864. The ILI9806E is comprised of a 1441-channel source driver, an gate-IC-less level shifter, and a power supply circuit. The ILI9806E supports 3-line serial peripheral interface to input commands. The ILI9806E supports a RGB (16-/18-/24-bit) data bus for video image display. For high-speed serial interface, the MIPI DSI interface mode, the ILI9806E supports two data lanes and one clock lane for high-speed and low power transmission in both directions with low EMI .
no idea what a MIPI DSI interface is, but an FPGA should eat it !!!
seems to imply a 10 pin interface see datasheet page 20.
needs SPI to set register IM[3:0] to 0111 or 1111, then its activated, with data on HS_D0P,HS_D0N, HS_D1P, HS_D1N, HS_CP, HS_CN, SDI,SDO,SCL(rising or falling edge) ,CSX
