Article Review: “Apple Inc. To Improve Screen Quality”
By Felice Medders
Apple Inc., who is currently dependent upon other manufacturers for their mobile device displays, filed for a patent to create an energy saving organic light-emitting diode (OLED) display. While traditional OLEDs are already more energy efficient than other displays, like LCDs, they still aren’t 100% efficient and many users of the iPhone 4S have been complaining about the quick drain on the device power. An excerpt from the patent filing stated, "The relative power inefficiency in display white spaces using an OLED display may be particularly problematic in certain contexts. For example, certain applications, such as word processing, spreadsheet design and use, database design and use, e-mail, and other business or productivity applications, typically utilize dark or black alphanumeric characters on a white background, such as to simulate writing or printing on a sheet of paper."
Apple’s proposed solution has a transparent OLED display panel that will be positioned in front of a solid white background layer, like a white transflective sheet. In addition, the display will have an opacity switchable layer between the OLED panel and the background layer. A side benefit to Apple is that the Apple logo can be place on the transflective sheet as well so the logo will show even when the device is off.
