Do all LCD displays have power adapters?
The power interface reads "enter 12V DC" or "enter 220V exchange", 12V is the adapter, and the 220V does not use the adapter.Liquid crystal display (LCD) a type of display used in digital timepieces and many portable computers. The LCD showed two polarizing materials, liquid crystal solutions between them. When the current passes through the liquid, the crystals are rearranged so that the light does not pass through them. Therefore, each crystal is like a shutter that allows light to pass through and to block light. At present, LCD products are developing towards light, thin, short and small targets, and the display products with a long history in computer peripherals are of course no exception. The portability and handling for the premise, show the traditional way such as CRT CRT display and LED display panel and so on, are subject to the volume is too large or huge power consumption and other factors, the actual needs of users can not be reached. And the development of LCD technology just meets the current trend of information products, whether it is right angle display, low power consumption, small size, or zero radiation, etc., can allow users to enjoy the best visual environment.
Liquid crystal display internal use of 12 V DC, must be lowered through the adapter, ultra-thin display adapter is generally external, ordinary display is usually built-in, of course, built-in more convenientTo supplement your questions, I would add, that direct look at the power display interface, if the interface is a diameter of about 5 mm circular interface, a fine pin in the middle, that is to use the adapter, if it is a square with trapezoid with three pins thicker than the interface, which first pin is longer, it is not the display adapter.There is also a simpler way to see if the power interface says "enter 12V DC" or "enter 220V exchange", 12V is the adapter, and 220V does not use the adapter
Having an outside, no outside, just inside the display.
