What is the difference between the touch types of each model of iPhone 12?

All of Apple’s iPhone 12 models, OLED panels will be used and consisted of four models. There are three sizes, 5.4 inches, 6.1 inches, and 6.7 inches, respectively, and 6.1 inches are divided into two models.

Samsung Display and LG Display have begun preparing to mass-produce, with recent orders from Apple. Samsung Display plans to supply OLED panels of all sizes, LG Display plans to supply 6.1-inch OLED panels, and there are differences in touch type by size.

First, on-cell touch which a touch electrode is formed on a thin film encapsulation (TFE) is applied to 5.4 inch and 6.7 inch models. Each panel maker is called Y-OCTA (YOUM on-cell touch AMOLED), ToE (touch on encapsulation), FMLOC (flexible multi-layer on-cell touch), and unlike add-on touch, a touch electrode is formed directly on the upper layer without base films. Due to this, the on-cell touch has a higher process difficulty than the add-on touch, but it is advantageous to fabricate a thin OLED panel thickness, and the process cost is also reduced.

Add-on method is applied to 6.1 inches. A touch electrode is formed on the base film, and is attached on the TFE by adhesive. It has the advantage that the process is simpler than on-cell touch.

Recently, rumors that BOE is supplying 5.4 inch and 6.1 inch OLED panels to Apple have turned around, but 5.4 inch is on-cell touch type and it is still difficult to supply for iPhone 12 due to technical difficulty. BOE is developing a 6.1-inch OLED panel and has not received calls yet.

Apple’s new iPhone 12 will be consisted of 4 models, and all 4 models are expected to adopt OLED. The general lineup of the iPhone 12 is the 5.4 inch iPhone 12 and the 6.1 inch iPhone 12 Max, and the pro lineup is the 6.1 inch iPhone Pro and the 6.7 inch iPhone Pro Max.

Recently, rumors are floating that BOE will supply OLED of 5.4 inch and 6.1 inch general models, and Samsung Display will supply OLED of 6.1 inch and 6.7 inch pro models. Due to the news that Chinese OLED panel manufacturer BOE is supplying OLEDs to Apple, the interest of OLED-related companies such as light-emitting material companies and component companies is growing day by day.

According to UBI Research, BOE is developing 5.4 inch and 6.1 inch OLEDs, but has not received any calls from Apple. In the current situation, Samsung Display plans to supply 5.4 inch, 6.1 inch, and 6.7 inch OLEDs, and LG Display and BOE are developing 6.1 inch OLEDs.

The BOE hasn’t gotten a clear call yet, but there’s plenty of time left for the mass production of the iPhone 12, so there’s plenty of room for the BOE to get a call from Apple. While the production of the iPhone 12 is likely to be delayed by about a month due to the corona incident, it usually takes 4 ~ 5 months from the OLED panel test to the mass production of the set, so there is enough time.
