Abstract

A method is described which allows the design of a font permitting substantially improved legibility for information shown on a high capacity liquid crystal display of low resolution and contrast. (Image Omitted) High capacity liquid crystal displays have the problem of both low resolution and contrast. The low resolution results in a sparse font. The sparser the font and the lower the contrast, the less the legibility (visibility) of information displayed. (Sparse fonts are also a constraint on CRTs, but these display devices generally have higher contrast.) Therefore, any technique which enhances the perceived contrast or resolution makes a significant impact on improving the legibility (and the perceived quality of the display). The following techniques enhance the perceived quality of the display.
