Apple apparently wants to take iPhone 6 and its other devices further with a new patent grant.
According to the U.S. Patent and Trademark Office, a patent published on Feb. 27 proved Apple seeks to ensure its devices are scratch-resistant as possible. With the upcoming release of iPhone 6, it may be possible for people to see a smartphone sporting a self-healing coating. What should people expect?
The patent goes by "Systems and Methods for Preventing Light Guide Plate Scratching Artifacts." According to the invention, Apple will be using self-healing teflon coatings to protect the surface of its devices, especially the backlight. This has been a problem among the users and their devices for quite some time. Also, the Retina displays found on Apple devices may soon appear even more appealing as it pushes to clean the surfaces of its products.
According to the patent background from Apple as quoted in Patently Apple:
"Electronic displays commonly appear in electronic devices such as televisions, computers, and phones. LCD pixels do not produce their own light. Rather, a backlight unit lights the LCD pixels from behind. The backlight unit may include a light source, a light guide plate, and a diffuser. The light source emits light into the light guide plate, which distributes the light across the diffuser. "
"The diffuser diffuses the light into the LCD. Since the materials that form the light guide plate and the diffuser may stick to one another, a binder material and beads may be placed between the light guide plate and the diffuser to perform an anti-wetting function. During vibration reliability testing or certain real-world use cases, however, the beads could scratch the light guide plate. When the beads scratch the light guide plate, undesirable display screen artifacts appearing as white spots may occur."
The featured technology will allow devices to prevent scratching artifacts. It will also describe how an electronic device can come with a processor to produce image data and display to show the image data. The display may feature a liquid crystal display panel along with a backlight unit.
Apple gives the patent credits to the following: Victor Yin, Eric Benson and Jun Qi.
