LG Display ups smartphone resolution to 2560 x 1440 on 5.5-inch screen

The new panel is also thinner than its predecessor

LG Display has developed a 5.5-inch screen for next generation smartphones with 2560 x 1440 pixel resolution, which is the highest to date, according to the company.

Bigger screens and higher resolutions are key ways for smartphone vendors to convince consumers to buy new devices, an opportunity LG does not aim to miss as a display supplier.

The combination of the 2560 x 1440 pixel resolution and the 5.5-inch screen equals a density of 538 pixels-per-inch. That compares to the HTC One's 468 ppi on a 4.7-inch screen and the Samsung's Galaxy S4's 441 ppi on a 5-inch screen.

The higher resolution will, for example, allow users to see a full view of a PC-version Web page on the screen without any image distortion, according to LG.

LG calls the screen the world's first Quad HD AH-IPS LCD panel. The quad is a reference to the fact it has four times more pixels than a screen with a 1,280 x 720 resolution.

But the new panel isn't just about the resolution. It will also help vendors build even thinner devices. The panel is 1.21 millimeters thick, which is 12 percent less than the company's 5.2-inch Full HD panel, which was released last month.

For now, the company is keeping quiet on when the first smartphones equipped with the screen will be launched.

Windows 10 for Business / Dell XPS 13

I’d happily recommend this touchscreen laptop and Windows 10 as a great way to get serious work done at a desk or on the road.

Ultimately, I think the Windows 10 environment is excellent for me as it caters for so many different uses. The inclusion of the Xbox app is also great for when you need some downtime too!

Windows 10 / Lenovo Yoga 910

For me, the Xbox Play Anywhere is a great new feature as it allows you to play your current Xbox games with higher resolutions and better graphics without forking out extra cash for another copy. Although available titles are still scarce, but I’m sure it will grow in time.

First impression on unpacking the Q702 test unit was the solid feel and clean, minimalist styling.

For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.
