What is scaler ?


- CRT can do resolution conversion

but LCD and PDP do not conversion

- Acceptinginput images from multiple sources and displaying

them on any flat panel display

- Scaler is most important IC in flat panel display

Scaler


10/61

Anothercomponents


1) Video Decoder For Multistandard color decoding : NTSC-M, S-VHS, MPEG Decoder, ATSC

Caption Mixing

2) Sound Processor

Sound Processors covers the sound processing ofall TV standards

balance, bass, treble, loudness, volume Control

Process Nicam, FM Stereo, FM Mono

3) Power IC ( Small Power IC)

Regulator

DDC(DC DC Converter)

4) Etc. Switch, ADC, MPEG Decoder, Sound AMP(Analog and Digital)


11/61

TV signal types


1. RF(Radio Frequency)- 50~900Mz Frequency Domain

- Composite signal+sound signal

2. CVBS(Usually AV)

- Composite video and sound signal

3. Super VHS

- Separate Y and C from composite signal

4. RGB

- Usually use PC, 15pin D-sub

5. Analog Component (Y,Pb,Pr)

- Usually Component

6. Digital Component(Y,Cb,Cr)

7. DVI(Digital Visual Interface)

- Standard from DDWG(Digital Display Working Group)- TMDS(Transition Minimized Differential Signaling Signal)

8. HDMI(High Definition Multimedia Interface)

- DVI+Digital Sound

Power part is composed ofpower board and main board(small power)

Check connectors between power board and main board

Check main board power output on the board

When you check main board power(small power IC), There are two types ofpower IC. One is PWM type, another is regulator type. PWM type should

check after inductor. Regulator type should check on the output pin.

Check each Voltage output
