Circuit Operation Theory

I. Introduction:

DV172 model is a 17” SXGA (1280x1024) 18 bits color TFT LCD monitor with multi-media function.
The features of DV172 are as below,
(a)Dual signal input supported for a 15pins D-sub and a DVI-D input connectors.
(b)It’s compliant with VESA DPMS spec to offer a smart power management and power saving function.
(c)OSD menu supported for users to control the adjustable items and get some information about this monitor.
(d)”Auto” button function supported to offer users an easy method to set all adjustable & controlled items well

by just pressing one button, “Auto”.
(e)VESA DDC2B function supported.
(f)Audio function supported with 2 speakers.

II. Block diagram

DV172 consists of a head and a stand (base). The head consists of a LCD module with 4 lamps, a power
board (include AC-DC, inverter power & audio circuit), a control board and an interface board. The block
diagram is shown as below.

(a) Circuit operation theory: (The scaling IC used in DV172 is Genesis gm5120)

A basic operation theory for this interface board in Analog input signals processing, the scaling IC
inside A/D converter will convert analog input signals of Red, Green and Blue to 8 bits digital signals of
Red, Green and Blue, and for interface board in DVI-D(TMDS) digital input signals processing, the scaling
IC inside TMDS receiver will convert TMDS signals to 8 bits digital signals of Red, Green and Blue. Then
no matter input signals Analog or DVI-D(TMDS) format are, they have been converted to 8 bits digital Red,
Green and Blue signals, and the scaling IC inside MCU and scaling control circuit will start to do timing
signal detecting and calculating to output the proper LCD panel signals to LCD panel circuit.

The timing signal detecting function in the scaling IC is to detect whether input H-sync, V-sync or
digital pixel clock signals’ status have been changed by host PC system, then it will do short-time picture
blanking, signal processing and converting again if input signals have been changed.

The scaling IC inside OSD circuit will be programmed to an OSD menu which can be showed on the
screen to offer adjustable functions to end-users to control and adjust some picture settings by themselves.

After the scaling IC internal signal processing is done, it will output the digital RGB data, the H-sync,
V-sync, pixel clock and DE(data enable) signal to LVDS transmitter and then to LCD panel driver circuit.

There are two kinds of EEPROM used in interface board, one is 24C02 which is used to store DDC

DV172 LCD Monitor Service Guide

data, we also call it, DDC IC, and another is to store OSD common data and those picture controlled and
data.

Flash-Rom is to store the source code which will be accessed by the scaling IC inside MCU to run
program.

(b) IC introduction:

1.) DDC (Display Data Channel) function: We use DDC IC to support DDC/2B function. DDC data is
stored in 24C02(EEPROM). Those data related to LCD monitor specification. PC can read them by
“SDA” and “SCL”(“DSDA” & “DSCL” for DVI-D input port) serial communication for I2C
communication for DDC2B.

2.) Gm5120 IC: There are A/DC, TMDS receiver, Scaling, OSD, MCU in the gm5120 IC. Scaling IC is
revolutionary scaling engine, capable of expanding any source resolution to a highly uniform and sharp
image or down scaling from UXGA, combined with the critically proven integrated 8 bit triple-ADC
and patented Rapid-lock digital clock recovery system. It also support detect mode and DPMS control.

Circuit Operation Theory

MCU control unit, it controls all the functions of this interface board, just like the OSD display setting,
the adjustable items, adjusted data storage, the external IIC communication, support DDC2B.

3.) EEPROM: All the adjustable data and user settings are stored in EEPROM (24C16).

4.) FLASH ROM: To store source code which will be accessed by Scaling IC inside MCU to run program.

(a) EMI Filter

This circuit (fig. 2) is designed to inhibit electrical and magnetic interference for meeting FCC, VDE,

VCCI standard requirements.

Circuit Operation Theory

Fig. 2

(b) Rectifier and filter

AC Voltage (90-264V) is rectified and filtered by BD601, C605 (See Fig 3) and the DC Output

voltage is 1.4*(AC input). (See Fig.3)

Fig. 3

(c) Switching element and Isolation power transformer

When the Q601 turns on, energy is stored in the transformer. During Q601 turn-off period, the stored
energy is delivered to the secondary of transformer. R607, C607 and D601 is a snubber circuit. R615 is
current sense resistor to control output power. (See Fig.4)

The current mode control IC UC3842B is used to control PWM. When the VCC terminal of it gets
16V, IC601 turns on. +5V will be set up at Pin8 through soft start circuit, which includes R617, C611,
D606 and D605. R616 and C610 generate a fixed frequency saw-tooth wave at Pin4.

3.1) ON/OFF SWITCH

Circuit Operation Theory

The turn-on voltage was controlled by R756 and R757.The inverter was turned on or off by the
switching transistors Q761 and Q757, Also regulator IC751 is control by Q761 and Q757 decide
supply 15V to inverter part or instead.

DV172 LCD Monitor Service Guide

3.2) PWM Control circuit

Circuit Operation Theory

TL1451 is a dual PWM controller.C765 and R765 decide the working frequency.BLT_ADJ
signal is from control board, control pulse width then decide how much energy delivery to CCFL also
decide CCFL brightness. Q741 and Q742 be the buffer to rise the drive capability and the totem poles
circuit can improve a capable of driving for Q743.C770 decide the striking time delay.

11

DV172 LCD Monitor Service Guide

3.3) Oscillator Circuit

Circuit Operation Theory

Royer circuit uses the characteristic of transformer saturation to oscillate. When the DC power inject,
Q759 or Q760 will turns on, and the current Ic increases. After a period, the transistor will leave the

saturation status and Vce increase. The result causes the voltage of primary coil get lower. Finally the
transistor turn off, and another transistor turn on. These statuses are repeated and the pin7 and pin8 of
T751 will get a Sin Wave to turn on CCFL.

C.) Control board introduction:

The main parts of the control board are a push button, and a led.

(a) Push button:

It’s a simple switch function, pressing it for “ON” to do the auto adjustment

function, releasing it for “OFF” to do nothing.

(b) Led:

It indicates the DPMS status of this LCD monitor; green light means DPMS on (Normal

operating condition). Amber light means DPMS off (Power off condition).
