<p><b>New page</b></p><div>== Screen Information ==<br />
* For example, 32x240 screen, can display PS16 string 20 char per line<br />
* Screen top left corner is (0,0)<br />
* Color is 64K -> actually 65536 color -> RGB565 -> 32*64*32=65536<br />
* Common color is 0~63 -> common color is first 16 kinds, for example 0 = black, 1 = red, ..<br />
