7-1 Circuit Description
The DLP TV is largely divided into: Power part, Engine part and Main parts.
The ass’y that consists of the DMD board, Detect (Actuator) board, LED light source, LED driver board illumination part, Color
sensor and optical devices is called the Engine.
The main board parts receive the AV signals to output voice signals and process the remote control signals.
The engine part displays the video data on the screen, which is generated in the main board.
The AV signals are input through the main and rear boards which processes the CPU functions, MPEG and I2S.
Finally, the improved DNle image is sent to the DMD engine board.
The final data by LED light source is processed in DDP3021 of the DMD board to display the image on the DMD panel.
This image is created by the light of the LED light source through the illumination part and Optical Module which is enlarged and
projected onto the screen.
This is the DLP of the K8 type that the actuator operates additionally during this process.
The power terminal generates the DC power needed for the product and sends it to the main board. The main board supplies the
power to the digital and DMD boards.
In the meantime, the power source board supplies DC220V - 400V directly to the Sub SMPS board. And then Sub SMPS board
supplies 12V and 16V to the LED Driver board.
The LED Driver board is like a stabilizer for lighting the LED light source.
The ultimate purpose of the TV set is to project an image onto the screen and output the voice signals synchronized with the image.
