The world of smartphones is growing with many new improvements and enhancements and there seems to be no saturation of any kind. Even though, many of the enhancements are made under the hood, display is an area where OEMs keep experimenting with the resolution and pixel strength. Following this trend, the current-generation devices are boasting the now-famous Quad HD displays. In the current scenario, the Samsung Galaxy S5's LTE-A variant beats other smartphones with a pixel rich 576 ppi. The recent news is that Sharp is likely working on a 5.5-inch screen with "4K IGZO LCD" display.

The aforementioned combination of screen size, followed by, a 4K display translates to a resolution of 2,160 x 4,096 pixels and an insane pixel density of 842 ppi. Apparently, Sharp showcased its recent addition i.e. a 4.1-inch Quad HD IGZO LCD display, bundled with a screen resolution of 1,600 x 2,560 pixels. Therefore, the display details boil down to a pixel density of roughly 736 ppi. This metric is significantly higher than the current devices flaunting the same Quad HD display, according to Phone Arena.

Going by Sharp's report, the display metric mentioned above is the same as the pixel density boasted by a smartphone or a phablet with a 6-inch display and 2,160 x 3,840 pixels resolution. Despite this, the company was able to achieve similar pixel strength with only a 4.1-inch display. Sharp has set a time frame of 2016 to launch the smartphone with 4K display. However, the design samples will head to manufacturers in 2015.

It is worth mentioning that, Sharp recently brought the concept of bezel-free, edge-less display to life, with the release of "Sharp Aquos Crystal" smartphone. In particular, the gap bordering the periphery of the display is virtually non-existent. Therefore, it makes the screen look as though it extends to the corners of the device.

In order to accomplish the unique edge-less display, the company ended up re-locating the front-facing camera, proximity/light sensor and the notification light to the tail-end of the screen. The flipside, however, is that the handset does not come with earpiece speaker and therefore, the call quality is quite a letdown, says Phone Arena. Alternatively, the company has relied on the direct wave receiver that vibrates the entire handset to produce sound. Reportedly, this concept is similar to the bone conduction technology.

On the other hand, Sharp is very cautious when it comes to the price range. The Sharp Aquos Crystal will set the buyers back by only $149.99 from Boost Mobile as a prepaid handset.
