Description
The HD66787 handles 262,144 TFT colors and can drive a TFT color liquid crystal display of
176RGB x 240 dots with an incorporated RAM compliant to a graphics display of 176 RGB x 240 dots at
maximum, a 528-channel source driver, and a power supply circuit. The HD66787 generates signals to
control panel-integrated gate circuit to drive a TFT panel with incorporated gate driver with a single chip.
The HD66787’s bit-operation functions, 8/9/16/18-bit high-speed bus interface, and high-speed RAM-write
functions enable efficient transfer of data and high-speed data update on a graphics RAM. The HD66787
incorporates 6/16/18-bit RGB interface (VSYNC, HSYNC, DOTCLK, ENABLE, and PD 17 to 0) and
VSYNC interface (system interface
+
VSYNC) as an interface for moving picture display. With a window
address function that facilitates the moving picture display in an arbitrary area and simultaneous display of
moving pictures and the contents of the internal RAM, the HD66787 enables moving picture display not
constrained by the still picture area. Accordingly, the data transmission is reduced to minimum, thereby
saving power consumed by a system as a whole when displaying moving pictures.
The HD66787 supports power-saving operation up to the power supply voltage of 2.4V with a voltage
follower circuit that generate voltage to drive liquid crystal. The HD66787 also incorporates 8-color
display and standby functions that allow precise power control by software. These features make this LSI
the ideal solution for any medium or small sized portable battery-driven products such as digital cellular
phones supporting WWW browsers or small PDA, where long battery life and board size are major concern.
