AMOLED display gives Samsung Galaxy Tab 7.7 the edge on weight, thickness, battery life

April 2, 2012 — Samsung Electronics launched the Galaxy Tab 7.7 in 2012, a commercial high-volume tablet based on a medium-sized active-matrix organic light-emitting diode (AMOLED) display. AMOLED offers benefits in the weight, thickness, and battery life, but this comes at a higher material cost, says research firm Displaybank, part of IHS.

Though Galaxy Tab 7.7 uses a 7.7" screen, it supports 1280 x 800 resolution, the same as the Samsung’s 10.1" tablet. It is also the thinnest — 7.98mm — of the products released so far. The tablet’s battery capacity is 2100mAh, the highest among 7" products. And finally, it is the lightest — 335g — of products in its size group. These superlatives were achieved from adopting AMOLED for the display, but the accompanying increase in main material cost was inevitable.

Displaybank performed analyis on Samsung Electronics’ Galaxy Tab 7, Apple’s iPad 1 and 2, and other tablets, comparing these to the innovation, cost competitiveness, and supply chain of major components of Galaxy Tab 7.7 (see the table at top).
