Sharp Wants To Produce Displays With 600ppi. Does That Make Sense?

Only when I hold my LG G2 right in front of my nose, I can imagine just pixels. The full-HD enough so my display resolution completely. Probably the Japanese electronics manufacturer SHARP disagrees. In early 2015, they want to start with the mass production of displays with a pixel density of 600ppi. Does that even make sense?

Samsung and HTC have changed nothing in their new flagship Smartphone Galaxy S5 and one M8 on the resolution of the screens, compared to the previous models. Both loosen with 1920 x 1080 pixels, so full-HD, on. To change only the display sizes.

The oppo find 7 makes it different. It’s the first Smartphone with a screen resolution of 2560 x 1440 resolution after vivo XPlay 3 S. The result is a pixel density of 534ppi. And if that’s not enough sharp announced now displays, which have a pixel density of 600ppi. The 2880 x 1620 pixels would a display with a diagonal of 5.5 inches.


This is too cumbersome, you can use also a PPI calculator.

The result we then in pixel per inch specified (ppi = pixels per inch). It indicates how many pixels on a square inch.

Because it comes repeatedly at the various resolutions to confusion, here is a small list:

  • HD = 1280 x 720 pixels
  • = Full HD 1920 x 1080 pixels
  • Quad HD / QHD / WQHD pixels = 2560 x 1440 (quadrupled HD resolution)
  • Quad full HD / ultra HD / UHD = 3840 x 2160 pixels (quadrupling full HD resolution)
  • 4 K = 4096 x 2304 pixels

In this overview of various devices and their pixel density, is clear: oppo hits with the 7 find all other smartphones.

Sharp against Japan display and Samsung

Sharp display wants to work first on a 5.5-inch, that has a pixel density of 600ppi. At this size, the 2880 x 1620 pixels are. So halfway between full HD and ultra HD. Later, still displays in sizes 7 and 9 inches should follow. The target’s, 4 K content to be able to represent on small devices.

The competition is planning similar displays. The world market leader Japan display and Samsung have also for 2015 announced 4 K display. With “only” a 10 inch screen with the four times HD resolution in the store has Japan display.
Also LG makes displays. In the rumor mill, it is speculated that even LG equips the new flagship with a QHD display. LG has now confirmed this information. Today, officially a 5.5-inch display with a resolution of 2560 x 1440 pixels was presented.

Does that even make sense?

I remember always like to transition from my iPhone 3GS to iPhone 4. The resolution of the iPhone 4 compared to its predecessor has quadrupled. In other words: double PPI. From 163 pixels per inch, 326 were then. That was awesome. At that time the sharpest display in a Smartphone. Finally, all writings were razor sharp.

The normal human eye can detect no individual pixels about 300ppi. Possibly differences can be observed only at very delicate lines. The manufacturer should work on stromsparenderen displays rather than more and more pixels in a small screen to squeezing. Each pixel consumes power. The display becomes an even bigger energy guzzlers than otherwise at a higher pixel density.

Sharp panels works not only on the very high resolution screens, but also on so-called Igzo. These have a pixel density of maximum 300ppi, are for very low power, and could in the future be used in mid-range of smartphones and wearables.

I find this trend, with increasingly higher resolutions in the Smartphone area, not very good. I am well equipped with my full-HD screen. The same principle applies in the camera segment. With more megapixels, digital cameras sell better than that with less. The image quality not only depends on the amount of pixels.
