DESCRIPTION OF BLOCK DIAGRAM

1. Video Control Circuit

1) TDA4885 (U101) receives the video signal from PC

and amplifies the levels of video signal (0V~0.7V), and

controls the contrast signal.

2) The biases of A/D inputs control the reference output

voltages of TDA4885 (U101) to proper R, G, B bias

levels through the Diodes (D101, D102, D103).

4) The EX-OR (U604) device outputs the voltage levels to

decide the polarities of HSYNCIN and VSYNCIN that

supply the sync signals to the PLL IC and MICOM.

2. A/D Converter Circuit

1) AD9483 (U201) converts from the analog video signal

to the digital signal. For this function, its DC 2.5V

output is connected to VREF_IN and it samples the

input signal between 2.0V~3.0V. (The reference

voltage of the sampling is 2.5V.)

2) The frequency range of 8-bit digital output is from

12.5MHz to 67.5MHz with respect to modes.

3) The status of power down pin is low for normal state

and high for power down state.

3. Features of ICS1522 PLL IC

1) ICS1522 (U11) generates the pixel clock for each

mode with respect to internal register setting, which is

used to sampling circuitry.

The range of the pixel clock is approximately from

25MHz to 135MHz

4. Video Process Circuit

This circuit consists of MXIC (U501) and frame

memorys (U401, 402, 403) which convert frame date

of input signal to 60Hz frame date. This function is

processed by MX88272. The MX88272 (U501) gets

the video signal converted analog to digital,

interpolates input to 1280x1024 resolution signal and

outputs 8-bit R, G, B, DHS, DVS and DE signals to the

transmitter (U701, U702).

5. LVDS Circuit

LVDS transmitter (U701, U702) delivers digital signal

to the receiver of module by the voltage swing of 1V.

The peripheral circuitry of transmitter gets the DHS,

DVS, DEN, DISPCLK signal, outputs LVDS signal. At

the power down mode, MICOM lets the power down

signal be low and Shuton pin be active low.

6. Input Switching Circuit

This circuit consists of BA7657F (U601), slide switch

and TTL gates. BA7657F (U601) switch analog R, G,

B signal to be entered form 15p D-SUB A(J2) or B(J3).

If the position of slide switch is A; R, G, B signal andH/V Sync are entered from D-SUB A. If the Position of

slide switch is B; R, G, B signal and H/V sync are

entered from D-SUB B. If the position of slide switch is

Auto; R, G, B signal and H/V sync are automatically

selected A or B by control signal of MICOM. But if A

and B are incidentally connected, system display OSD,

2 Input active... select A or B.

TTL gates (U602, U603, U604) switch H/V sync to be

entered from D-SUB A or B.

7. DC/DC Converter

This curcuit supplies stand-by 5V (5VST) that is made

using IC U801 regulator for MICOM and SYNC

processing.

The 5VDD voltage is converted using MAX785 (U802)

and supply to IC need to it.

The 8VA is converted using 8V regulator (U808) and

supply to video pre-amp.

The 3.3V voltage is converted using 6 Diodes and

supply to IC need to it.

The 5VA is converted using 5V regulator (U809) and

supply to A/D converter and PLL IC.

The state of power down make all voltage except

5VST down using SHDN.

8. System Controller (08XL36) Circuit

This curcuit consists of EEPROM IC (U902) which

stores control data, RESET IC (U904) and LED driver

Q01 and Q02 indicate that power is ON or OFF.

The operating procedures of MICOM and its

associated circuit are as follows:

7/27/2019 Lq800 Tft Sm

11/34

1) The MICOM distinguishes polarity and frequency of

the horizontal sync and the vertical sync are supplied

from signal cable. The controlled data of each mode is

stored in EEPROM.

2) User can adjust screen condition by each OSD

function. (H-Position, V-Position, Clock, Clock Phase,

... etc.)

9. DDC Circuit

This circuit consists of MICOM (U901) and bidirection

switching IC (U2).

1) Bidirection switching IC switch I2C line for DDC

communication by control signal of MICOM (U901).

2) The MICOM has D-SCL, D-SDA line for sending andreceiving data to adjust line through 15-pin D-sub

connector.

3) The data of EDID DDC information is stored in

EEPROM IC (U902).

10. OSD Control Circuit

When the MX88272 outputs the area which is able to

display overlay using OSDBLNK PIN of MX88272.

OSD (On-Screen-Display) device (U502) outputs

display data as the timing of the signal.

11. Power Module Circuit

This block supplies the +12V to the inverter for the

backlight voltage of module and the +5V for data

control of LCD module.

That is, SI4925DY (Q01) is switched by TR Q12 for

module voltage.

All adjustment are thoroughly checked and corrected

when the monitor leaves the factory, but sometimes

several minor adjustment may be required.

Adjustment should be following procedure and after

warming up for a minimum of 10 minutes.
