2. Identification methods: resistive capacitive approach of identification and the identification method is essentially the identical, straight common method, the color standard system and a number of typical strategy three types. The fundamental unit of capacitance with Farah (F) that other units are: millifarad (mF), microfarad (uF), sodium Act (nF), picofarads (pF). Where: 1 farad = 103 mm micro-strategy = method = 106 109 = 1012 pF sodium law of big capacity capacitor whose capacitance worth is marked straight on the capacitor, this kind of as 10 uF/16V smaller capability of the capacitor worth in capacitor on its capability to use the letters letters or digits that method: 1m = 1000 uF 1P2 = 1.2PF 1n = 1000PF digital representation: basic dimension capability with three digits, the first two represents a valid amount, the third digit is the magnification. This kind of as: 102, stated ten × 102PF = 1000PF 224 mentioned 22 × 104PF = .22 uF3, capacitance tolerance error table symbols FGJKLM ± 1% ± two% ± 5% ± ten% ± 15% ± 20%, this kind of as: a ceramic capacitor that capability for the 104J . one uF, error of ± 5%.
As the LED-backlit display shows the essential principle is no various with the conventional CCFL-backlit show, are relying on the LCD display back light lamps render the image. And the LCD pixel LCD is composed of a lot of, more than a prolonged period of continuous use, will make crystal aging or burn, damage in the event, there will be the highlight we say, dead pixels, the injury is is permanent, irreparable.

In common, to extend the existence of the display, not to make the LCD keep track of is turned on for a prolonged time (far more than 72 hours continuous), if not in time, turn off the show, or let the display white screen right up until you can enter standby mode .

Prevent hard object bump, scratch
For most of the LED-backlit show, they are the most vulnerable place is the display, the average hardness of the screen are the following in the 3H (pencil hardness), commonly do not spend interest really uncomplicated to use by other gadgets “friendly fire”, and after the display by loss suggests that this LED keep track of in essence scrapped.

To avoid achievable troubles, we can opt for a passive protection and active protection, passive protection is the range of Internet cafes, bedroom and other public areas you can pick to buy a monitor with tempered glass, so you can make your show “bulletproof, fire and water does not invade, “but will have an effect on the color display, there will be reflections and proactive protection is in normal use be doubly cautious, as far as doable on the display may possibly lead to harm to the items away from the display, and clean the display they also gently wipe as much as achievable, to decrease the probability of injury.

Do not dismantle the show
LCD show with other electronic items, also is a precision instrument for non-professionals as not to get rid of their displays. Although the operating voltage of LED backlight has been greatly diminished compared to standard CCFL, commonly much less than 20V, but the instantaneous internal stress is even now a great danger, in addition to rising the show is straightforward to fault.
