White is Sony Magic
Sony has provided its own trademark solution for viewing your screen under the sun. It has applied its latest screen technology, WhiteMagic, to one of its newest releases for the Xperia smartphone line- Xperia P. It has employed a fourth subpixel by adding a white layer to blue, green and red that is usually found in traditional screens. The integration of this new technology with advanced mathematical procedures has doubled the efficiency for saving power and producing brighter results for your viewing experience.
It sets your display to optimum brightness when subject to outdoor mode, while it sets your phone to save energy when indoors. It gets rid of the common notion that greater features require more power to function. How is the technology applied to Xperia P’s LCD display? Common LCD screens have three subpixels horizontally aligned beside one another for every pixel [red, blue, green]. Sony added a white subpixel thus providing a total of 4 subpixels for every pixel called RGBW.
The subpixels in common LCD screens are composed of liquid crystals in 3 primary colors through which backlight is filtered in various proportions to create various colors. The backlight passes through the three subpixels in right proportions to represent the white. With WhiteMagic technology, the light is also filtered through the added white subpixel in order to create a true white. This will increase the brightness of your display as compared to your traditional LCD or OLED screens.
The double brightness comes with power-saving capability of up to 50% of your backlight energy based on the light of your surroundings and user preference. It also makes things easier for you as it brings out more details from your videos and images. The outdoor mode can be compared to using all LED lamps to produce backlight, while indoor uses only half of them. Indoor conserves your energy by performing an analysis of the color composition of the individual content to address problems with color distortion.
The light sensor that is built within devices such as Xperia P measures the amount of surrounding light to automatically adapt your screen settings to either outdoor mode or indoor mode. It still gives you the freedom to set your own comfort. You can manually select your preferred setting for the intensity of brightness. This will turn off the light sensor as you will be creating the same setting for both indoor and outdoor mode.
There are two modes of saving power. In bright mode, your smart phone will prioritize clarity and brightness to maximize your viewing capabilities while being able to save power compared to other devices when indoors. The power save mode combines WhiteMagic technology with lower backlight level to save more energy. It results in 50% lower consumption of energy for your backlight compared to using bright mode. This will allow you to prolong your battery life for extended use. These two modes are both capable of adapting to the amount of light provided by your surroundings to maintain optimum viewing at all times.
