Evolution of Low-Power High-
Speed Rail-to-Rail Buffer Amplifier for LCD
Applications liquid crystal display (LCD)
television (TV), there is a large demand for
developing high resolution, high color depth
driver ICs. The panel of an LCD-TV is larger and
higher definition than that of a computer monitor
and its color quality requires more accuracy. For
example, computer monitors have (262,144) or
(16,777,216) colors. However, the LCD-TV needs
(1,073,741,824) colors. In order to develop a highquality
display module, the driver system should
be promoted to higher color depth and resolution.
The evolution of compact, light-weight, lowpower,
and high-quality displays has caused a
large demand for liquid crystal display (LCD)
drivers, with features such as low cost, low power
dissipation, high speed, and high resolution. An
LCD driver is generally composed of column
drivers, gate drivers, a timing controller, and a
reference source. Column drivers are especially
importan
