QHD panel on smartphones is important and manufacturers all over the world are already working on it. The concept is not altogether a brand new one as most of the manufacturers have already come up with QHD devices. To name a few Oppo Find 7a and Vivo Xplay 3S are two devices, which have already been launched with the QHD panel.
Samsung's Galaxy S5 was also rumored to come with the similar QHD display but unfortunately it didn't. Nonetheless, other rumors making rounds are that the Galaxy F might be the QHD variant of the the Galaxy S5 smartphone.
Now another company has released a phenomenal display which offers a QHD resolution with the highest pixel density. Another major difference between the already used QHD panels of Oppo and Vivo is that these were LCD, while the latest one comes with a Super AMOLED display technology.
The latest display technology comes from the Taiwanese company called AU Optronics. And according to the press release issued by the company, it has "successfully developed the world's highest-resolution 5.7-inch WQHD AMOLED panel." This Quad HD screens has 1440x2560 pixels of resolution, and breaks the 500ppi barrier, clocking in at exactly 513ppi.
The company said that it has also created a 6-inch Quad HD OLED panel. Surprisingly the company has also shown interest in small OLED screens as well, announcing a 1.6-inch panel for wearable devices.
AUO also released one of the thinnest OLED display packages, in the form of a 5-inch HD 720p screen with just 0.57mm thickness and 10-point touch, which is a prime candidate for ultrathin midrange phones.
