Five-inch FullHD from Sharp

    Just a few hours ago, Sharp announced that they were launching mass production of five-inch displays for mobile devices with a resolution of 1920 * 1080, which means a record 443ppi. Moreover, they promise to show a working prototype this week at an exhibition in Japan.

    They drew here such a scheme how it will work:

    On the one hand, it is very cool. You can naturally lie face on the phone and no pixels will be visible. And on the other hand, now I am writing this topic on a 10 "tablet with exactly the same resolution and with my absolutely healthy eyesight I can’t, with all the desire, calculate the height of the letters in pixels - I don’t see them at all. Everything is so smooth and clear that sometimes you even begin to miss the imperfection of the image.

    And, again, such a high resolution display will again impose an additional load on the video system of the mobile device, which will lead to energy losses, which again puts us away from the once-usual 5-8 days of the mobile phone working on a single charge.

    The only real use of such a wild density of peaches on such a small area I see only in helmets a la VRX and all their later counterparts, as well as in the newfangled Augmented reality, so that the glasses look cooler than the Terminator. But to those lines they, of course, still dig and dig. Indeed, for a helmet, screens are needed about an inch, and for glasses, generally 4 * 2mm, approximately so that the projector can be placed normally on the temple.

    It seems to me that they are more likely to construct flexible matrices with a transparency of more than 90 percent to place them directly on the glass, than they will get to the FullHD projector on the bow.

    In general, progress, of course, is pleasing and encouraging, although, personally, I would prefer that the volume of energy reserves in a cubic centimeter of batteries grow at the same rate than the number of points on the mobile displays. By 2015, you give 2200 ampere- hours to a standard battery * of a mobile phone weighing 18 grams!

    * Yes, I understand that licking such a battery == instant corpse. But I really want not to remember about the outlet for at least a couple of weeks.
