JBT6K47-AS
Source Driver for TFT LCD Panels
The JBT6K47-AS is a 64 gray-level, 240-channel-output source driver for TFT LCD panels. 6-bit digital input
enable to display colors using internal DA converter and five external power supplies. Also, JBT6K47-AS
incorporates power saving function to control recognition of the grayscale data input. When display performance is
not necessary, such as in a portable device, JBT6K47-AS ignores the grayscale input data.
Based on high-speed CMOS, the JBT6K47-AS offers both low power consumption and high-speed operation.
