General Description

The µ PD16781 is a source driver for 480-output TFT-LCDs, providing support for only striped pixel array LCD.

The driver consists of a shift register for generating the sampling timing and sample & hold circuits for sampling the analog voltage.

The high picture quality obtained by the alternate sample & hold execution of the two types of on-chip sample & hold circuits enables employment in applications such as car navigation panels.

Key Features

  • 5.0 V Drive (Dynamic range 4.6 VP-P, VDD2 = 5.0 V).
  • 480 Output channel.
  • fCLK = 20 MHz MAX. (VDD1 = 3.0 V).
  • 1-phase/3-phase sampling clocks supported.
  • Corresponds only to LCD of Stripe array color filter.
  • Two on-chip sample-and-hold circuits.
  • Small output deviation between pins (deviation between chip pins: ±20 mV MAX. ).
  • Switch between right and left shift using the R,/L pin.
  • Logic power supply voltage (VDD1): 3.0 t.
