Hi,
it's not easy to connect that type of display to the Pi without additional hardware due to the parallel 16-bit data bus.
You will need some form of latching the data bus in to 8-bit packets.

The HY28A-LCDB (as you mentioned), is much easier to connect to due to the SPI serial bus it uses for both display and touch panel.
See this example :

Yes over the last 18 months drivers and kernel have both been updated, therefore this post is not totally relevent, try this recent post as very recent:
