312-OUTPUT TFT-LCD FULL COLOR DRIVER
The µPD16602 is a TFT-LCD source driver with full color display capability. It is ideal for 1024 × 768 pixel (XGA) class
high definition displays. The internal circuit consists of 12 channels (4 × 3) of analog input pins, 12 channels of 16-bit shift
registers and 312 channels of sample & hold circuits (2 latch type).
Analog display signals are sampled in 12 channels simultaneously by the sample & hold circuits and they are output in
the next line. The output voltage of the sample & hold circuits is as great as 10.5 VP-P and maintains high accuracy with an
output deviation of ±20 mVMAX. Inputting analog display signals that been γ -processed in the previous stage signal
processing circuit allows realization of a high definition 256-gray-scale-equivalent full color display without requiring line
inversion.
FEATURES
• 4 × 3 (RGB)-channel analog input allows display signal input wiring to be reduced.
• High dynamic range (10.0 VP-PMIN. VDD2 = 11.0 V)
• High accuracy sample & hold circuits (output deviation; ±20 mVMAX., ±5.0 mVTYP.)
• High-speed sampling frequency (for both analog and digital; fmax. = 20 MHzMIN.)
• Low power control (reduction of output buffer bias current) function on chip
(operating power consumption; 82 mWTYP., VDD2 = 12.5 V)
• Bi-directional data store function on chip
• Corresponding to high-density mounting (slim TCP)
