Is the yield problem resolved? How In-cell defeats the enemy and wins

Since Apple began to use In-cell touch panels on the iPhone 5, the future development of In-cell has begun to attract attention. In particular, there is also a new generation of touch technology such as OGS on the market waiting to emerge, and it is also curious how In-cell will defeat the enemy.

Displaybank, the market research agency, pointed out that there are indeed some problems to be overcome in In-cell, such as its complicated panel structure leading to low yield and other problems. However, with the launch of the iPhone 5, In-cell yield problems have gradually been overcome, which also allowed mobile device manufacturers other than Apple to begin evaluating whether to use In-cell technology.

Compared with the traditional touch panel, because the screen of the In-cell panel is combined with the ITO touch sensing layer, the thickness of the screen is reduced, so that this panel has the advantages of higher light transmittance, narrow border, thinner and lighter. However, the most criticized problem of In-cell is its complex panel structure. It is understood that the excessively complicated three-dimensional structure of In-cell panels has indeed caused a certain degree of impact on mass production. Especially the high resolution of the products advertised by Apple, because the higher the resolution, the more complicated the panel structure, which makes the production process prone to defects, and the yield will also be lowered.

It is precisely because of the yield problem of In-cell that competitive technologies, including OGS, have very good opportunities this year. However, with the launch of the iPhone 5, the yield problem caused by its complex structure seems to have been gradually resolved, which also led the industry to explore the opportunities for In-cell to gain a lot of adoption this year.

Once the In-cell technology is favored by the market, the growth of the old GFF and GG plug-in panels will be more severely challenged. In contrast, suppliers of In-cell panels, including LGD, Sharp and Japan Display, will receive greater attention from the industry.
