G+FF vs On-cell: iPhone Hard OLED Display Manufacturing Process comparison


In the iPhone OLED screen replacement market, there are Hard OLED and Soft OLED. Let's compare the two manufacturing processes of iPhone rigid OLED screen G+FF and On-Cell. ZY Hard OLED uses the G+FF manufacturing process.


What is the On-cell process?

In the In-cell vs On-cell process comparison article, the formation process of the On-cell process is described in detail. The On-cell process comes from the touch screen production process developed by panel manufacturers. In the On-cell process, the TP layer is embedded in the OLED module. The TP layer is embedded in the OLED surface using the On-cell process, and the TP layer embedded inside the LCD screen is the In-cell process.


What is the G+FF process?

The G+FF process is a process developed by touch screen manufacturers. Touch screen manufacturers currently have four processes: OGS/G+G/G+F/G+FF, of which G+FF is the most used in mobile phone screens. It consists of a toughened cover plate and two layers of ITO film, and the two layers of film Film are connected by OCA.


G+FF screen advantages and disadvantages

G+FF uses a thin film as the signal function layer of the ITO carrier, and the supply of raw materials is stable and the stability is high. The light transmittance is above 91%, there is no polarization problem and rainbow pattern. 32 touch channels, touch-sensitive and smooth. The disadvantage of G+FF is that the service life of the film is average, about 2 to 3 years. In the mobile phone repair industry, the use time of the G+FF screen is sufficient.

On-cell screen advantages and disadvantages

In the Apple after-sales market, there is more demand in the iPhone Incell LCD market. On-cell products provided by mobile phone display manufacturers are scarce, and the number of manufacturers to choose from is also small. Coupled with the low process technology of On-cell external processing, the quality of the On-cell screen is not high. On-cell Hard OLED is gradually moving towards the development trend of low quality and low price. The advantages of the On-cell screen are similar to those of the In-cell. The touch sensing layer is integrated into the display module to make the screen thinner.
