Drive Circuit Architecture and Function Description
- Description of the function of each board
1) X Drive Board
This is connected to the X port part of the panel. 1) Sustain voltage waveform (including ERC) is output, and 2) Ve bias in the Scan
section is maintained.
2) Y Drive Board
This is connected to the Y port part of the panel. It outputs 1) Sustain voltage wave form (including ERC), and 2) Y Rising, Falling
Ramp waveform, and maintains 3) Vscan bias.
3) Y Buffer Board (Upper, Lower)
This board supplies the Scan waveform to the Y port and consists of Upper and Lower boards. For an HD grade unit, 6 scan dri-
ver ICs (TEXAS INSTRUMENT SN755867APZP: 64 outputs) are mounted on the board.
