Super HD AMOLED ! SMD continues to make progress increasing display pixel density.
September 12, 2011

Recently at IFA 2011 in Germany, SEC demonstrated a 5.3” AMOLED GALAXYNOTE and a 7.7” AMOLED GALAXYTAB 7.7.  The GALAXYNOTE with a 5.3” AMOLED, called Super HD AMOLED is designed with Pentile technology, which provides for increased pixel density.   In terms of ppi, the AMOLED displays have been noticeable lower than the 327 ppi of Apple’s retina display.  However, by incorporating PenTile technology, SMD developed a 170ppi 1280 x 800 in a 7.7” AMOLED display and 285ppi 1280 x 800 at a 5.3” AMOLED display.  SMD continues to make progress increasing display pixel density.  RGBG PenTile has been criticized in the past because it had a characteristic grain in some circumstances. On AMOLED especially it wound up being distracting more than it was novel, and on 4" displays, it seemed that subpixels were visible with the naked eye and average visual acuity. Furthermore there were some issues with an offset pattern like RGBG and the UI direction Android was taking. Single pixel wide UI elements, some text, and solid primary colors were the main culprits where RGBG could, without considerable scrutiny, look characteristically grainy. As the pixel density increases, these criticisms have been ameliorated.
