6.5 Passive/Active LCD Panel Support

S5U13706P00C100 Evaluation Board

Rev. 1.2

The S1D13706 directly supports:

• 4/8-bit single monochrome passive panels.

• 4/8/16-bit single color passive panels.

• 9/12/18-bit TFT active matrix panels.

• 18-bit Sharp HR-TFT panels.

• 18-bit Epson D-TFD panels.

All the necessary signals are provided on the 40-pin LCD connector, H1, and 16-pin

Extended LCD Connector, H2. For connection information, see Section 5, "LCD Interface

Pin Mapping" on page 14.

The S5U13706P00C100 does not provide a power supply for the LCD bias voltage needed

by passive LCD panels. An external power supply is required to provide the bias LCD

voltage to the LCD panel.

The buffered LCD connector (H1) provides the same LCD panel signals as those directly

from S1D13706, but with voltage-adapting buffers selectable to 3.3V or 5.0V. Pin 32 on

this connector provides a voltage level of 3.3V or 5.0V to the LCD panel logic (see "JP6 -

LCD Panel Voltage" on page 10 for information on setting the panel voltage).

The S1D13706 directly supports Sharp 18-bit HR-TFT and Epson 18-bit D-TFD panels.

The extended LCD connector (H2) provides the extra signals required to support these

panels. The signals on this connector are also buffered from the S1D13706 and adjustable

to 3.3V or 5.0V (see "JP6 - LCD Panel Voltage" on page 10 for details on setting the panel

voltage).

The S1D13706 uses CLKI and CLKI2 signals provided by two +5V oscillators. The oscil-

lators are mounted on the evaluation board in 14-pin DIP sockets. The 5V clock signals are

shifted to 3.3V which is accepted by the S1D13706.
