LCD Panel Scan system Drivers "High-Voltage Level-Shifting"

LCD Panel Scan system Drivers "High-Voltage Level-Shifting" 4:10 PM / Topi Dea / LCD,

The workings of the Scan-Driver panel there are several kinds. One of these was used by Samsung Panel called the "High-Voltage Level-Shifting". How to get pulsa2 drive, CKVB, CKV STVP can be understood with an example block diagram as shown below. Pulse-pulse CKV, CKVB, STVP used as pulse "Row driver" or also called "Gate

Pulse-pulse CKV, CKVB, STVP, formed from the pulse-pulse STV and CPV. Pulse-pulse CKV, CKVB, STVP has high voltage level of about 35-40v, and got positive suply of VGH (Von) and negative suply of VGL (Voff). Pulse-pulse CKV, CKVB, STVP from scan-driver ic broken into 2 lines. One line goes into the panel through the left side, and the other through the right side. Loss of pulse-pulse CKV, CKVB, STVP (due to short, line break up, or loss of voltage, VGH-VGL) on both sides will lead to a blank screen-no osd, whereas if only one side of the break up is usually the image still persists. High-voltge Shift-Registers on the Row-driver in the glass panel is sometimes damaged and result in impaired "double vertical picture". If only one side is sometimes damaged panels can still be repaired with break lines, CKVB, CKV STVP everything, or sometimes simply just one of the lines on the side of the damaged area. but this does not guarantee 100% will have to do.
