New iPad exposure: OLED screen is finally here 19th,Jan,2022

                                            On January 11, Korean media The Elec reported that Samsung Display will need to get a large order from Apple this year to expand its 8.5-generation (2200×2500mm) OLED panel production line. Products made by this production line will be used in the iPad Pro as soon as 2024.

One of the big problems with OLED screens is that they don't last long, and users typically spend a lot of time on their iPads. Apple hopes to solve this problem by stacking two-layer OLEDs, which can double the brightness of the screen and increase its lifespan by 4 times. After the lifespan is extended by 4 times, the problem of OLED aging has been greatly improved, and consumers are more likely to accept it.

The biggest hurdle for Apple to use OLED on the iPad is cost. Samsung currently does not have a panel product with double-layer OLED display, and it will cost a lot of money to develop and build a new production line. Previously, Samsung and Apple cut off the project of using OLED panels on the iPad Air, and the first OLED iPad will be the iPad Pro.

Stacking two-layer OLEDs will double the cost of materials, and TFTs (thin film transistors) have to support high-speed electron movement, which means LTPO (low temperature polysilicon oxide) must be used, which uses about 15 masks in the production process, This further increases the cost. Samsung can't afford the cost alone right now, and it needs a large order from Apple to spread the risk evenly.

After launching the first OLED iPad, Apple also plans to replace ordinary TFT with oxide TFT, which will be used in other product lines except iPhone and iPad. It requires fewer masks in production, resulting in significantly lower costs.

Apple has used mini-LED backlight panels on the 12.9-inch iPad Pro, and is still spending a lot of money to develop OLED panels for iPads, probably because the latter is cheaper and more power-efficient. After all, mini-LED uses a lot of lamp beads, and the cost of this piece is not easy to reduce. The pixels of the OLED screen are self-illuminating and consume less power.

After Apple applies this double-layer OLED panel on the iPad Pro, it may also bring it to the iPhone and other devices. At that time, the brightness of the iPhone will have a big jump, and it is not afraid to see clearly in strong sunlight.
