Abstract
Color active-matrix electrophoretic display (AMEPD) is
the inevitable trend for the applications of smart
handheld reading devices such as E-books and E-news.
This paper presents a normalized RGB color filter (CF)
design which achieves 15.66% full white reflectance,
10.80 contrast ratio, and 5.01% of National Television
System Committee (NTSC) color gamut. In addition, a new
storage method with a minimized lookup table that
significantly reduces the data storage space by $2n$ times of the conventional one, where n is the
number of gray levels. The prototyped controller has
connected to a 6” color AMEPD panel covered with
the normalized RGB structured CF, and an excellent
display quality has demonstrated the effectiveness of
the proposed controller design.
