Apple is reportedly testing new Color E-Ink technology for foldable devices and tablet applications.
The ink can produce full color at every pixel without using any color filter.
The reports come fromApple analyst Ming-Chi Kuo, saying Apple is testing color e-in displays for its future products.

According to Ming-Chi, the ink is well suited to enable a foldable devices low-power second screen experience.
And the larger, folded-out display can use more advanced technology for display.
According to KUO, the EPD is more energy-efficient than other display technology.

Apple might also use a color EDP display for a new class of tablet devices.
However, Samsung Galaxy Z Fold 3 or Oppo Find N use OLED panels for both displays.
The use of the E-Ink screen by Apple can make the outer display less responsive with few colors.

Kuo claims that it could be more power-efficient.
According to the reports, Apple plans to launch its first 9-inch foldable iPhone and iPad around 2025.
Theres a long time ahead so we will get much news about the Apple foldable devices before their launch.

All these are ongoing rumors that the company is designing a foldable iPad.
However, at present, Apple is not making any foldable.
Kuo says Apples foldable plan will first focus on medium-size devices and then on larger displays.
After that, Apple might expand it to small devices like iPhone.
