Various Parts of LCD monitor

Panel		Panel is where a vision is deplayed. They can be classified into laptop panel, desktop monitor panel, TV panel and application panel. The resolution of LCD monitor is usually fixed. 10.4 inches to 15 inches panels used for laptop have a resolution of 1024 X 768 but some model support upto 1400 X 1050 and 1600 X 1200. Monitor panels various from 15 inched to 23 inches and have a resolution of 1024 X 768 to 3840 X 2400.
TAB / IC		Tab/IC controls liquid crystal display panel.
Backlight		Unlike CRT, DPD, FDD, LCD panels cannot light by themselves, Thus a polarizer is attached for us to use in dark place, which equally irradiate light to the surface
AD Board		Ad board could be mother board in PC. Which pass visual signal to liquid crystal display. LCD handle visual signal in digital. Analog signal coming from VGA port of PC would be converted into digital signal for monitor to us.
Inverter		In order activated backlight lamp, 1.5kv of electricity should be provided. Inverter changes DC currency to AC currency in order backlight to activated.

Laptop Repair

One of feature of laptop is that it is combination of LCD monitor and computer itself.
Knowhow of laptop computer is a mixture of knowhow of repairing LCD monitor and knowhow of repairing computer.

Myung Information Technology has a Korea best LCD repairing technology with expensive equipment of cutting edge and accumulated research and development of LCD repairing technology and has started HDD repairing for the first time in Korea. Thus Myung Information Technology is the most suitable company for LCD repairing.

Major parts of Laptop

LCD		LCD panel of laptop computer is similar with that of desktop LCD monitor
HDD		Hard disk drive is a secondary storage device which reads and writes a data from spinning platter made out of round aluminum disc. Data could be stored in tracks of platter. Magnetic heads read and write data.

Quality of Repaired Product/ Warranty

• Repairing Quality
  Panel is usually made out of polarizer which displays image to LCD monitor, glass, TAB IC and Tab Board. These parts could be understood as the most essential parts of LCD monitor and which manufacturing methods are complicated and hard. There are not many companies which can make those parts. Only Samsung and LG have a technology to make them. Since LCD panel manufacturing is complicated, thus the repairing of them is not easy.

• Repairing Quality
  Myung Information Technology provide three (3) months warranty for the repaired product. If a similar problem has occurred within three (3) month, we will provide free repairing service.

Repairing Facilities

Clean Room		A highly complicated TFT-LCD is made in cleanroom facilities The product is made of many advanced technology and a single dust would cause a fatal errors on the product.
