TFT-LCD Timing Controller. The logic architecture is imple-
mented using standard and default timing controller function-
ality based on an Embedded Gate Array. The device is
reconfigurable to the needs of a specific application by pro-
viding user-defined specifications or customer supplied
VHDL/Verilog code.
The FPD87352CXA is an ideal Timing Controller for LCD TV
Applications. It has a unique feature, RTC that will improve
the intra-gray level response time of a LCD TV panel. Im-
proving the intra-gray level response time of the LCD panel
will result in a dramatically improved Motion Picture Image
Quality of video content that are displayed on the LCD panel.
The RTC feature is accomplished through application of a
Boost or Overdrive Voltage that will force the LC material to
respond more rapidly. This Boost or Overdrive is accom-
plished through combination of an internal or external EE-
PROM LUT (Look Up Table), which contains the boost/
overdrive levels, and external memory that acts as a Frame
Buffer.
The FPD87352CXA is a timing controller that combines an
LVDS single pixel input interface with National鈥檚 Reduced
Swing Differential Signaling (RSDS) output column driver
interface for XGA/WXGA/HDTV I,II,- resolutions. It resides
on the Flat Panel Display and provides the data buffering
and control signal generation. FPD-Link, a lower dynamic
power, low EMI (Electro Magnetic Interference) interface is
used between this timing controller and the host system. A
RSDS interface is used between the timing controller and
the column drivers.
The dual 13/10 pair differential bus conveys up to 24-bit
color data for XGA, WXGA and HDTV panels.
