Other symptoms of the Character LCD Module panel

A white or black screen
LCD TV in the case of normal light backlight display only "black and white" (Always) or "black" (often dark), mostly lost by the LCD panel supply voltage caused.
When the LCD panel is lost when the power supply voltage, liquid crystal panel for Always (NW), the performance of its failure "black and white"; normally black (NB) LCD panel, the failure manifested as "black". Therefore, no matter the "black" or "black and white" fault should first check the power supply and the power supply circuit of the LCD screen in the insurance resistor (fuse).lcd modules
Grating alternating light and dark
Grating alternating light and dark is generally caused by the LCD panel internal circuitry Weld or poor contact.
3 Huaping
Huaping is basically due to a circuit fault.
Should first rule out a fracture of the screen line, and then look at the LCD panel supply voltage has been added to the panel, proceeding to examine the level of high pressure and negative pressure output. A considerable portion of the video "is caused by abnormal line driver IC.
4 by poor polarizer due to symptoms
Bad cause of failure by the LCD panel polarizer phenomenon. This failure in amateur conditions are generally more difficult to deal with.
Backlight unit due to symptoms
Failures caused by the backlight unit in addition to the poor backlight, the backlight brightness reduction, as well as uneven backlight, black or white, circular, linear patterns such as the phenomenon of light leakage, as well as the backlight at the foreign matter on the screen.256x64 oled
(6) moiré
The moiré is a result caused by the LCD panel and backlight module notch direction does not match the optical interference phenomenon, which is a phenomenon caused by a result of the structure of the liquid crystal panel, are often not as fault.
