General Description
The FPD80200 timing controllers (TCONs) are designed to
meet the needs of today鈥檚 advanced LCD TV applications.
The FPD80200 supports both WXGA (1280 x 768) and
WXGA+ (1366 x 768) resolutions with true 8-bit color (16.7
million colors).
When combined with the FPD48084 column driver, the
FPD80200 provides true independent gamma curves for the
red, green, and blue subpixels through internal lookup tables
(LUTs). The FPD80200 also uses an advanced Response
Time Compensation algorithm to improve the motion video
performance of the LCD panel.
The FPD80200 TCONs incorporate National鈥檚 PPDS
鈩?/div>
inter-
face (Point to Point Differential Signaling) that enables ad-
vanced features, independent column driver control, large
panel sizes, and lower overall system cost.
Panel timing and control parameters can be programmed
into an internal ROM for production or changed using and
external EEPROM for initial product development.
