       So, the major difference between the 3A and the 2A quality is their flex cable. The flex cable is original in the 3A quality but it is copied in the 2A quality. Before proceeding to their differences, you need a sound knowledge about the flex cable. Flex Cable  refers to any variety of electrical cable that is both flat and flexible. Flex Cables are usually straight connections without any components. is a miniaturized form of ribbon cable, which is also flat and flexible. The cable usually consists of a flat and flexible plastic film base, with multiple metallic conductors bonded to one surface. Often, each end of the cable is reinforced with a stiffener to make insertion easier or to provide strain relief. The stiffener makes the end of the cable slightly thicker. The main body of the flexible flat cable of the invention includes a particular quantity of cores and sheath layers. The core includes a plurality of single conductor wires or a plurality of twisted conductor wires compressively combined by top and bottom sheath layers located above and below the core to form a flexible flat cable main body.

      There are many differences between an original and a copy flex cable. Some differences will be illuminated here in brief. In the OEM flex cable, there is a QR code right on the metal piece on the back of the connector. You will have to peel off the gray foam covering on it in order to see it. There is a code on the LCD connecter of an original flex cable which is missing in the copy flex cable. There is another code on the flat flex cable body. That code is clearer on the original flex cable than the copy version. There is another way to distinguish the original flex cable, test the flexibility of the flex cable. When you bend the flex cable, the OEM flex cable feels soft while for the aftermarket one, it feels hard and solid.

       So, the differences between the original and copy flex cable was illustrated above. The original one is used in the 3A quality LCD screen and the copied one is used in the 2A quality LCD. You must be wondering why the original flex cable is better. Well, the conductor wires of the flex cable can endure high temperature. So, they last longer than the conductor wires of the copied cable. The vertical arrangement of the circuits of the main body of the flex cable also enables it to conduct electricity in an arranged pattern. So, it has better transmission efficiency. The irregular pattern of circuits on the main body of the copied cable causes irregular flow of electricity. Therefore, it is more vulnerable than the original cable.
