Description
The LGDP4524 is a 262,144-color one-chip controller driver LSI for a TFT liquid crystal display with
resolution of 176 RGB x 220 dots, comprising a 528-channel source driver, RAM for graphics data of 176
RGB x 220 dots at maximum, a gate driver and a power supply circuit.
The LGDP4524 supports high-speed parallel interfaces to 8-, 9-, 16-, 18-bit ports and a function to write
RAM data in high speed for transferring data efficiently and rewriting RAM graphics data in high speed.
In addition, the LGDP4524 incorporates 6-, 16-, 18-bit RGB interfaces (VSYNC, HSYNC, DOTCLK,
ENABLE, and DB[17:0]) and a VSYNC interface (system interface + VSYNC) for displaying a moving
picture, which, with use of window address function, enable the LGDP4524 to display a moving picture
easily at a position specified by a user and still pictures in other areas on the screen simultaneously. Since
this combination allows transferring only moving picture data while retaining still picture data in the
internal RAM intact, data transfer can be minimized and power consumption by the entire system is
reduced.
The LGDP4524 can operate with low I/O interface power supply up to 1.65V, with an incorporated
voltage follower circuit to generate voltage levels for driving an LCD. The LGDP4524 also supports a
function to display in 8 colors and a standby mode, allowing for precise power control by software. These
features make the LGDP4524 an ideal LCD driver for medium or small sized portable products
supporting WWW browsers such as digital cellular phones or small PDAs, where long battery life is a
measure concern.
