Apple developing thinner OLED panels for foldable displays

Apple has begun developing thinner OLED panels that could be used in foldable displays in the future.

Apple is developing OLED panels without polarizers, which typically only allow light in specific directions to pass through, thereby improving the visibility of the display.

One disadvantage of polarizing films is that they tend to reduce brightness, thereby reducing the luminous efficiency of the panel. To offset this, manufacturers often increase the power consumption of panels, but this shortens their lifespan.

The report cited supply chain sources as saying that by removing the polarizer, Apple will be able to make the panel significantly thinner, making it more suitable for foldable panels. In theory, Apple could also apply a different technology that would be as effective as a polarizer but avoid the trade-offs mentioned above.

Samsung has used an OLED panel without a polarizer in the Galaxy Z Fold 3, combined with its "Eco Square" technology that increases light transmittance while reducing power consumption.

Apple is working with LG to develop foldable OLED display panels with ultra-thin cover glass for future iPad and MacBook models, although in this case, the site says the panels that will be used will contain Ultra-thin cover glass replaces the polyimide currently used in most other foldable displays.

Apple is exploring a full-screen foldable laptop with a display size of about 20 inches. Young believes the devices could form an entirely new product category for Apple and result in a dual-purpose product that could potentially function as a laptop with a full-size on-screen keyboard when folded, and as a monitor when unfolded and paired with the display. use together. External keyboard.

Apple is testing a device with a 9-inch foldable OLED display with a PPI between the iPhone and iPad. Kuo believes that Apple's foldable product development will initially focus on mid-sized devices, followed by devices with larger displays, and finally expand to smaller devices like the ‌‌iPhone‌‌.
