SPFD5408 Datasheet – 720-channel 6-bit Source Driver – Orise
720-channel 6-bit Source Driver with System-on-chip for Color Amorphous TFT-LCDs
SPFD5408 overview
The SPFD5408 is a 720-channel 6-bit Source Driver with System-on-chip for Color Amorphous TFT-LCDs made by ORISE Technology. The absolute maximum ratings table on this page lists the 10 limits from the manufacturer's datasheet that must not be exceeded. This page brings together the SPFD5408 maximum ratings, with the full datasheet PDF to preview below or download.
The SPFD5408A, a 262144-color System-on-Chip (SoC) driver LSI designed for small and medium sizes of TFT LCD display, is capable of supporting up to 240xRGBx320 in resolution which can be achieved by the designated RAM for graphic data. The 720-channel source driver has true 6-bit resolution, which generates 64 Gamma-corrected values by an internal D/A converter.
The SPFD5408A is able to operate with low IO interface power supply up to 1.6V and incorporate with several charge pumps to generate various voltage levels that form an on-chip power management system for gate driver and source driver.
The built-in timing controller in SPFD5408A can support several interfaces for the diverse request of medium or small size portable display. SPFD5408A provides system interfaces, which include 8-/9-/16-/18-bit parallel interfaces and serial interface (SPI), to configure system. Not only can the system interfaces be used to configure system, they can also access RAM at high speed for still picture display. In addition, the SPFD5408A incorporates 6, 16, and 18-bit RGB interfaces for picture movement display. The SPFD5408A also supports a function to display eight colors and a standby mode for power control consideration.
