4. CIRCUIT DESCRIPTION

1. GENERAL

Circuit will be described in reference to the QD-101MM block diagram in Fig. 2. Composite video signal which enters via pin jack connector is converted into the digital RGB in the composite video input circuit by the control signal from the I2C bus controller. The signal then enters the signal selector circuit. Computer analog signal enters via the 15-pin connector and is processed through the computer analog input circuit and the A/D conversion circuit. The signal is then converted into the digital RGB signal and enters the signal selector circuit. Digital video signal from IBM PC EGA or CGA enters via the 15-pin connector is input into the signal selector circuit. The signal selected in the signal selector circuit is written into the field memory. The writing operation into the field memory is controlled by signals which are generated in the IC100 by HSYNC. VSYNC. Since the LCD control is asynchronous with the computer signal, FRCK. FRRS is generated in the IC100, and is read out at their timings. The audio control circuit controls the audio signal input from the audio input terminal, according to the control signal from IC100. IC400(MPU) controls IC100, IC107 (I2C bus controller) by the key operation from SW PWB. Since control data from the key is stored into EEPROM, the set data is memorized even if the power is turned off.

2. COMPUTER SIGNAL INPUT CIRCUIT

In addition to composite video signal, QD-101MM can receive the computer analog RGB signal and the computer digital RGB signals of MDA, CGA, EGA. These signals enter each input circuit via the 15-pin connector (J2), pin jack (CN600), and S-terminal(CN601). After they are converted into the digital signals, they are input to the signal selector or directly to the signal selector circuit. Refer to MAIN CIRCUIT No.3.

2.1.Computer digital signal input circuit

The computer digital signal is input to Pins 2, 3, 4, 5, 12 and 15 of J2, and is directly sent to the signal selector. EGA outputs the video signal at the 6-bit TTL level. (R, G, B, r, g, b) CGA outputs the video signal at the 4-bit TTL level. (R, G, B ,I) MDA outputs the video signal at the 2-bit TTL level. (Mono, Video, I) As basic, the pins of J2 output the following signals.

The signals are converted into 8-bit digital signals by the A/D converter(IC315~317). The computer analog signals are given to Pin 21 of the A/D converter, are divided by 256 between the voltages given to Pin 18(VRT) and Pin 24(VRB), and are digitally converted. The following table shows the reference voltage which is given to the A/D converter.

2.3.Threshold level generation circuit

In order to convert the computer and composite analog signal into digital, it is necessary to set the threshold level on the A/D converter. As shown in Fig. 3, VRT and VRB voltages are set on the basis of the reference power of ZD1. VRT can be varied by key operation. As the adjusting method from the main body, the MENU button and SELECT button are used to display the contrast adjustment in the screen and to allow the set value to be changed with UP and DOWN selector buttons.

5. PLL CIRCUIT

The dot clock (VCOIN) is generated by the PLL circuit shown in Fig.6. The dot clock is necessary to sample the video signal from the computer and change it into the suitable dot data. Hsync signal from computer enters into IC100. This signal is compared frequency and phase with the feed-back signal, which is generated from VCOIN by the phase comparator in IC100. If any error of phase or frequency occurs between Hsync and VCOIN, LOW or HIGH level is output at PBD of IC100, and when both frequency and phase agree with each other, high impedance is output. The output signal from the PDB terminal is converted into a DC voltage by a loop filter and then controls the VCO. To select the high band or low band, either VCO is selected according to the signals from No. 120 pin and No. 119 pin of IC100.

Fig.6 PLL Circuit

6. MEMORY CIRCUIT

BLOCK DIAGRAM is shown in Fig.2.

6.1.Field memory writing

When data sent from the signal selector is written into the field memory(IC103~105), FWCK (clock slightly later than CLK) generated from the memory controller in IC100 is used.

6.2.Field memory reading

The clock (FRCK) and control signals which are generated in the field memory reading signal generating circuit in IC100 are used to read data from the field memory. Reading is asynchronous with writing. In the ordinary mode, data written into the field memory are color-compensated and are sent to LCD. In the enlargement mode, the enlargement control signal is sent to the field memory from the field memory writing/reading signal generating circuit in IC100 to make the enlargement display possible.

6.3.Menu, message display memory

The menu and message display is stored in the ROM area of IC400(MPU). When the menu button is first pressed, MPU will write data and address into VRAM (IC108, 111) via IC100. Moreover, VRAM data is read via IC100. The data is sent to LCD at the timing of LCD.

7. VARIOUS FUNCTIONS OF IC400(H8/3256 M.P.U)

IC400 is a microcomputer which is provided with a set of 16-bit free running timer and 2 channels of SCI in addition to 48K-byte PROM/2K-byte RAM.

7.1.Key data and various functions

The keys (DOWN, UP, SELECT, MENU, RESET) provided on the main body of QD-101MM switches and selects the adjustment mode displayed in the LCD screen as well as gives the direct commands to IC400.

1) DOWN This key decreases the adjustment items selected by the select key, step by step.

2) UP Being opposite to DOWN, the key increases the adjustment item, step by step.

3) SELECT This key is used to select the adjustment mode in the menu screen which is displayed by the MENU key. Every push of this key can change the adjustment item, step by step.

4) MENU This key is used to switch the menu screen.

5) RESET This key is used to set the initial values of the computer. When this key is pressed, the adjustment items are all returned to the initial statuses.

7.2.EEPROM control function

The EEPROM(IC413, 414) area is provided to write the timing set values of each computer when it is connected to QD-101MM. The timing set values are written into EEPROM under the following four conditions.

1. All resetting

2. Resetting

3. Power turn-off

4. The connected computer is changed.

Here, writing into EEPROM is executed only when the set value is changed.

7.3.Reset circuit

The circuit diagram is shown in MAIN CURCUIT No.4. IC407(TL7705CPS-B) detects the power voltage, V and generates the RESET signal. If V

drops below the detection voltage (TYP4.5V) when

CPU

, of IC400 and its surrounding circuit,

CPU

the power is turned off, IC407 shifts the level of the RESET signal to “Low”. If V V

rises to exceed the total voltage of the detection voltage VS1 and hysteresis width

CPU

(TYP15mV), IC407 starts charging the timing capacitor(Ct) with a constant current.

HYS1

After (TP0=1.3XCtX10[S]), IC407 shifts the RESET signal to “High” level. (See Fig. 8.) IC411(S-8054ALB) detects the power voltage VCC to generate the power OFF signal. If V

drops below the detection voltage VS2 (TYP4. 15V) when the power is turned off, IC411 shifts the power OFF detection level to “Low”. If VCC rises beyond the total voltage of the detection voltage VS2 and hysteresis voltage V

HYS2

(TYP200mV) when the power is turned on, IC411 shifts the power OFF signal to “High” level. (See Fig. 9.)

On the other hand, Vcpu is backed up by C425 (220mF) so that it can maintain 4.5V for the time of TW after the trailing edge of the power OFF detection signal. See Fig. 11. (TW is the time for IC400 to retreat the data to EEPROM.) If V

drops below VS1, the RESET signal level is

8. LCD CONTROL CIRCUIT

LCD control signal is slower than the video signal of the computer. While the video signal is serial data, the LCD display data is given as 4-bit parallel data for each RGB. In order to display the bit signal of the computer in LCD, it is necessary to store the data of one screen in the memory and read out the image data of one screen at the drive timing of LCD. To control them, the field memory is controlled by the memory controller in IC100 as shown in the block diagram in Fig. 2.

9.3.Handling the LCD panel

1. The LCD unit is assembled to very high density, do not attempt to disassemble it.

2. The polarizing plate is very easy to scratch, take extra care when handling it.

3. When cleaning the surface of the LCD panel, use absorbent cotton or soft cloth and carefully wipe the surface.

4. The LCD panel will become discolored or stained if any moisture remains on the surface for a long period of time.

5. The LCD panel is made of glass. If it is hit by any hard object or is dropped, it may crack.Handle it very carefully.

6. CMOS LSI which is used in the LCD unit is very sensitive to static electricity. To prevent damage to the LCD unit from static electricity it is necessary for all service technicians to use a conductive mat and wrist strap to ground themselves when servicing the unit.

IC1 in Fig. 14 is a controller for a fixed frequency pulse width modulation(PWM) switching regulator and has two constant voltage controllers. One controller is used to generate a 5V power supply(V

CPU,VCC

) from the input power supply VIN(12VDC). The other one is for V

LCD

IC1 has a saw-tooth wave oscillator built in whose oscillating frequency is determined by capacitor C30 connected to pin 1 and resister R29 connected to pin2. In this circuit configuration, a saw-tooth wave of approx.75KHz is observed at pin 1 of IC1. Basically this sawtooth wave is compared with a control signal observed at pin5 of IC1. Only while the voltage of the saw-tooth wave is lower than the control signal voltage, the period between pin 7 of IC1 is "L" becomes longer. As a result the period between external transistor Q11 and Q10 is conductive becomes longer. The output voltage is fed back to pin 3 of IC1. An error amplifier in IC1 makes a comparison between the half of the reference voltage and the feed-back signal to pin 3 and generates a control signal(pin5 of IC1). As explained above the output voltage is stabilized by the pulse width from pin 7, which is generated by comparing the control signal with the saw-tooth wave. V

is adjusted to 5.1V while VCC is 5V. This is done because the load on the VCC is greater than

CPU

the load on V

and the forward voltages of D8, D9, and D10 are higher than that of D7.The

CPU

voltage supplied to pin 6 of IC1 is called a dead time control signal. It controls the maximum ON period of the output transistor in IC1. The maximum ON period is realized on IC1 by shorting pin 6 and pin 16. The saw-tooth wave oscillator of pin 1 of IC1 is used also for the control of this 5V power supply(V

). The operation of the circuit is similar to that of the other 5V power supply(V

LCD

CPU

and VCC). The output voltage is fed back to pin 14 of IC1. The control signal is produced using a voltage generated by dividing the reference voltage inputted to pin 13 of IC1, and the feed back signal. The output voltage is stabilized by the pulse width from pin 10, which is generated by comparing the control signal with the saw-tooth wave. V

is adjusted to 5.0V with VR2.

1 1. INVERTER CIRCUIT

The Inverter circuit board supplies the high voltage AC to the cold-cathode fluorescent tube used as backlight illumination for the TFT panel. The Inverter circuit is supplied the voltage from CN20 on the Main PWB and it gives to the coldcathode fluorescent tube. The lighting level control can be varied by turning VR50. (Note) (1) Inverter circuit is very dengerous because it is outputted the high voltage(max AC1300V).

Make sure that the monitor's power switch is in the OFF position when servicing Inverter circuit board.

(2) Inverter circuit board can not be replaced. It needs to be replaced when it is failed.
