The primary skills for projection capacitive touch panels that demand the use of multi-point touch are divided into film type and glass type. The Apple camp uses glass type projection capacitors, while the non Apple camp mainly uses film type PET capacitors.

In order to effectively reduce the cost of touch modules and satisfy the trend of frivolous end consumer electronics market, touch industry players have actively laid out and developed OGS, embedded touch or GF film skills in the past two years. The OGS skill is to combine ITO glass and protective glass into one piece of glass, which not only reduces one piece of glass but also saves a bonding process. It reduces the thickness by about 0.4 millimeters compared to two-piece G/G products, and is estimated to save about five cost points.

Compared to the active layout of OGS skills in external professional touch module factories, the primary TFT or AMOLED panel factories tend to develop embedded skills (In Cell Touch), which can be roughly divided into two types of skills: In cell and On cell. The advantages of embedded touch control are the same, which can save a piece of glass and a bonding process. However, due to the need for embedded skill panel factories to have LTPS skills, the entry threshold is relatively high, and the current process quality rate is still low, so the impact on external touch control panels in the short term is not significant. However, with Apple's support for embedded touch technology and recent active collaboration with Japanese and Korean businesses, Samsung will also launch AMOLED products this year that incorporate On cell touch technology. The future of embedded touch technology is still not to be underestimated.
