MODULE FUNCTION & DEFINITION
1. The function of each part
Part name Main function
Y-Board (Scan Driver) Execution of the scan and sustain operation connecting scan electrode (Y-electrode) and FPC of panel
Z-Board (Common Sustain Driver) Execution of the sustain operation connecting sustain electrode (Z-electrode) and FPC of panel
X-Board (Address Driver) Execution of the address operation connecting the botton plate address electrode (X-electrode) and FPC of panel
Control Board Distribution to X, Y, Z board after creation of display data and driver timing for an image and sound signal to be input from outside
DC/DC-2 Board Distribution to X, Y, Z board after conversion from input voltage of Vs, Va, Voc to circuit logic voltage (5V)
FPC (Flexible Plate Circuit) The pattern connection of PCB and panel
COF (Chip On Film) It means to integrate a kind of IC Chip with FPC
2. A term and definition of defect
2.1 CELL DEFECT
Term The actual state A cause
Non lighting Cell Defect Cell is always “Off”▶a different thing orstructural defect of Cell
Flashing Cell Defect Cell repeat On / Off ▶a different thing orstructural defect of Cell
Non-extinguishing Cell Defect Cell is always “On”▶a different thing orstructural defect of Cell
High Intensity Cell Defect A cell is the brighter than others on same color ▶a different thing orstructural defect of Cell
