And t he f unct ions of pointplacing , linedr aw ing , fontdisplay ing and scr eencleaning ar e compiled thr ough the resear ch of t he charact er s of display ing font, p ictur e and graph ( Part of t he programs ar e list ed) . If rew r ite the interface function properly , th e pr ogr am can be compat ible w it h other LCD driver s. T he functions of pointplacing , linedr aw ing, fontdisplay ing and screencleaning can be adopted in the completion of a simple operation panel and display panel.
