Implementation of a Retina Display in iPad 3 he forced Apple Lossless Audio CODEC (ALAC), to slightly increase the thickness of the tablet to implement two LEDs to illuminate the screen, but also a larger capacity battery. In the iPad 4 Apple Lossless Audio CODEC (ALAC), slightly streamlined the manufacturing process of the Retina Display, but only with iPad 5 would be prepared to partially reduce energy consumption, giving up one of the LEDs used for lighting. However Apple Lossless Audio CODEC (ALAC), she would not be satisfied with what she has now, so in an invention patent describes a device which could further reduce the energy consumption of its Retina Displays.
Apple's latest display invention covers techniques for reducing the power consumption of display devices are provided. In one embodiment, a display device includes a timing controller that may control a rate at which frames are refreshed on a display. The timing controller may cause the frames to refresh at different rates, depending on the image data received at the timing controller. For example, if the image data is not static, the frames may be refreshed at a first rate. However, if the image data is static, the frames may be refreshed at a lower, second rate to reduce the power consumption of the display device.
The device described by Apple is a controller that controls the period of time between which the display information is updated, i.e. a refresh rate controller. This device could dynamically change the refresh rate of the screen depending on the images displayed on it, that is, in the case of static images the refresh period would be longer, while in the case of dynamic ones it would have the opposite effect. The idea is to balance the refresh times to reduce the energy consumption of the screen, without affecting the user experience.
Considering that we are talking about a patent, for now no one knows when this technology could arrive in Retina Displays, but its use could reduce energy consumption by up to 50%.
