Typical screens for smartphones now are characterized by a pixel density of about 400-550 ppi. Moreover, because of the transition to the displays 18:9, 19:9, and other similar, diagonally, significantly increased, and the resolution is practically not changed (the chassis — Full HD+), causing the density of screens in modern smartphones sometimes even a bit lower than previously.
But now not about it. Today, Sony introduced the OLED display, whose pixel density is approximately an order of magnitude greater than typical screens for smartphones. And when I say order, I mean order of magnitude, i.e. 10 times.
ECX339A screen is made with OLED technology and is characterized by resolution of 1600 x 1200 pixels at a diagonal of only about 0.5 inch. Accurate diagonal Sony does not specify, limited to the wording “0.5-type”. This is not a prototype, just the display is designed for smartphones as viewfinders for cameras. Sony itself does not specify a density, but if I counted correctly, it is around 4000 ppi! If anyone is interested in the formula, it looks like this: measures of resolution width and height you want to build in squares, and the numbers add up; the final number you need to extract the square root, and the result is divided by the value of the diagonal in inches.
Also Sony notes that its new screen, the pixel pitch is only 6.3 µm, which is a record in this segment. From the rest of the support frequency of 240 K/s, a maximum brightness of 1000 CD/m2 and the coverage of the color space sRGB 110%.
Mass production of such displays will begin in November, that is, in serial products we can expect in the next year. However, the price of this screen is $ 460. That is, they are clearly some time will be the prerogative of top-end cameras.
