1. Viewing Angle, Contrast Ratio, Response Time, Reflectance, and Chromaticity are measured at panel center.
2. Viewing Angle（θ, ψ）
Measurement is done on position 1.
Viewing angle origine is the axis normal to the flat panel. Left (L) and Right (R) value
are the maximum angles for which CR=10. Up (U) and (D) value are the maximum
angles for which CR=10.

Circuit Operation Theory
I. Introduction:
The Q7C3 (FP756) is a 17” SXGA (1280x1024) , 262 K colors(R, G, B 6-bit data) TFT LCD
monitor without multi-media function. It’s an analog interface LCD monitor with a 15 pins D-sub signal
cable and it’s compliant with VESA specification to offer a smart power management and power saving
function. It also offers OSD menu for users to control the adjustable items and get some information
about this monitor, and the best function is to offer users an easy method to set all adjustable items
well just by pressing one key, we called it “Auto key” which can auto adjusting all
controlled items. Q7C3 (FP756) also offer DDC2 function to meet VESA standard.
II. Block diagram
The Q7C3 (FP756) consists of a head and a stand (base).
The head consists of a LCD module
with 4 lamps, a power board (include AC/DC, DC/DC and inverter board), a control board and interface
BD. The block diagram is shown as below.

Circuit Operation Theory
(a) Circuit operation theory:
A basic operation theory for this interface board is to convert analog signals of Red, Green,
Blue. The scaling IC has internal A/D converter, internal OSD and auto detect input timing
functions. A/D converter is convert analog signal to digital data. OSD is offering adjustable
functions to end-user. Detect timing is for detect change mode. Scalar finally output the digital
RGB data, the Hsync, Vsync and pixel clock to LCD panel driver IC by RSDS interface. MCU also
embedded in PW133A controls system processing. EEPROM is stored DDC data, OSD common
data and user mode data. Flash-Rom is stored the source code which is accessed by 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” serial communication for I²C communication for DDC2B.
2.) PW133A IC : There are A/D, Scaling, OSD, MCU functions in the PW133A IC. Scaling IC is
revolutionary scaling engine, capable of expanding any source resolution to a highly uniform
and sharp image, 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. 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: We use 24C16 to store all the adjustable data and user settings.
4.) FLASH ROM: To stored the source code which is accessed by MCU to run program.

#3 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)

#4 Rectifier and filter
D701 and C703 are to produce DC output. L701 and C704 are to suppress high Frequency switching

#5 PWM Controller
The PWM controller NCP1200A implements a standard current mode architecture. With an internal
structure operating at a fixed 40KHz. Where the switch time is dictated by the peak current set-point.
When the current set-point falls below a given value. The output power demand diminishes, the IC
automatically enters the so-called skip cycle mode and provides excellent efficiency.

#6 Feedback circuit
PC123 is a photo-coupler and TL431 is a shunt regulation. They are used to detect the output
voltage change and be the primary and secondary isolation. When output voltage changes, the
feedback voltage will be compared and duty cycle will be decided to control the correct output
voltage. (See Fig.7)

(B)DC Power Input: To supply +15V to be VCC source Voltage for TDA7496 and built-in AC-DC board.
(C) Audio Input: connect with PC Audio output in 3.5mm to 3.5mm signal line.
(D) Speaker: Use 8 ohm and 28mmX40mm speaker (2W/per channel)
(E) DC Volume Control: The voltage range is 1 – 3.3 V (From MC)

A-3.) 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.
(c) 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).

3.Circuit Operation Theorem
3.1 ON/OFF SWITCH
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.

3.2 PWM Control circuit
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.

Circuit Operation Theory
3.3 Oscillator Circuit
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.
