Is it possible to display HTML page on a LCD display of a discovery board?
I am not aware of any webbrowser that could run on such a bare-metal system. A webbrowser is a BIG application, I doubt it would fit if anyone would try it.

My advise is to drop this line of tought. If you want a webinterface, serve the webpage (for instance to a mobile phone). If you want an interface, check for a graphics library. But it will be a LOT more work than you imagined.
