Main Board Parts

1. Inverter: A conversion device that converts DC

rated voltage/current to high ones necessary

for the panel lamp.

2. DC/DC(Regulator): General term for DC to DC

converting devices.

The IP board receives 5V and outputs 1.8 or

3.3V that is supplied to the scaler(SE656MR-

LF).

3. Power MosFET: The IP board receives 5V and

outputs a lower voltage in DPMS mode and

supplies the whole 5V for the panel operating

board in normal conditions. In that case, the

switching of Power MosFET is controlled by

Micom.

4. Scaler: Receives the digital TMDS and analog

R,G,B signals and convert them to proper reso-

lutions using up- or down- scaling that are

transferred to the panel in the LDVS formats.

5. Crystal(Oscillator): Use one 14.318MHz oscilla-

tor externally to supply power to both MCU and

Scaler at the same time.

6. SCALER & EEPROM: I2C is a two-way serial

bus of two lines that supports communications

across the integrated circuits as well as

between FLASH and EEPROM.

In particular, FLASH and Scaler(SE656MR-LF)

use the SDR direct bus for mutual communica-

tions, which is an effective, speedy system

because it allows 4 additional address/data

lines compared to the old serial systems.

7. Function Key: A certain keystroke generates a

certain electrical potential, which is transferred

into ADC input port of the Scaler and then con-

verted to a digital value by the A/D converter of

the chip. The digital value (data) is a clue to

which key is entered. In practical, the voltage

levels are set as below.
