smart board display upside down.In-Cell refers to the method of embedding a touch panel function to the liquid crystal pixels, i.e. displayed inside the screen embedded in a touch sensor function, the screen can become so thin. At the same time, the In-Cell screen must be embedded with a matching touch IC, otherwise it is easy to cause erroneous touch sensing signals or excessive noise. Therefore, for display panel manufacturers, the threshold for cutting into In-Cell / On-Cell touch screen technology is quite high, and it still needs to overcome the difficulty of low yield. Currently using In-Cell technology In addition to Apple's iPhone 5, there is also Nokia's Lumia920. The iPhone 5 has a thickness of 2.54 mm, and it can be 0.44 mm thinner using In-Cell technology, which accounts for about 25% of the total thickness reduction (1.7 mm). As shown in Figure 2, iPhone 5 has one less touch screen than iPhone 4S .
