VDD: digital logic voltage, typically 3.3V, the power supply for the logic circuit
AVDD: mains voltage, mainly used in Source Driver output voltage and the Gamma correction pixel voltage
VGH: Gate turn-on voltage, the gate voltage of the TFT for open
VGL: gate turn-off voltage, a TFT gate-off voltage
Vcom: Vcom voltage, Panel common electrode voltage, some integrated Gamma IC
fault abnormal performance of each voltage
VIN (12V / 5V), VDD (3V3) , VAA (15V) when no failure FIG screen;
VGL (-5 V), VGH (30V) when an image abnormality or fault to switch the image slowly;
the VCOM (7V) when a failure or an abnormal image flicker.

LCD driver circuit power supply system; the main four-way drive circuit required voltage:
1, VDD: generally 3.3V, for T-CON board integrated block power supply;
2, VGL: TFT TFT switch switch MOS tube off voltage, typically -5 V; 3, VGH: turn-on voltage of the TFT screen, typically 35V ~ 20V; 4, the VDA: screen data driving voltages, typically 14V ~ 20V, the gray scale voltage generated by the gamma correction circuit, Gray clock voltage of about 14 different ladder voltage;
5, Vcom: screen common electrode voltage (gamma correction voltage maximum of 1/2);
different screen VGL, VGH voltage values ??are different. Any of the above voltage problems, there will be different image failure, fault-prone parts.

Despite being more expensive than standard permanent outdoor toilets, portable toilets (Fig. 1) have several significant benefits as these are self-contained and can be placed almost anywhere. These days portable toilets are frequently seen at outdoor areas like construction sites, farms, camp sites...
