OTM8009A
1440-CHANNEL Source DRIVER
and 864 Gate DriverWITH
SYSTEM-ON-CHIP (SOC) FOR
Color Amophomous TFT LCD
1. GENERAL DESCRIPTION
The OTM8009A, a 16,777,216-color System-on-Chip (SoC) driver
LSI designed for small and medium sizes of TFT LCD display, is
capable of supporting up to 480xRGBx864 ( WVGA ) in resolution
which can be achieved by the integrated RAM for graphic data.
The 480-channel source driver has true 8-bit resolution, which
generates 256 Gamma-corrected values by an internal D/A
converter.
The OTM8009A is able to operate with low IO interface power
supply 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 OTM8009A can support several
interfaces for the diverse request of medium or small size portable
display. OTM8009A provides several system interfaces, which
include MIPI/MDDI/CPU/RGB/SPI/I2C. Not only can the system
interfaces be used to configure system, they can also access RAM
at high speed for still picture display. The OTM8009A also
supports a function to display eight colors and a standby mode for
power control consideration. For further power control, the
dynamic backlight control function basing on displaying image
content is also supported.
