Comparing the Application of Display Technologies in Leading Smart Phones Display Size: For each of the given phones above, display size is shown as a diagonal measurement of the viewable area. There the pixel density chart below the viewing area in millimetres was used for the area calculations Panel Thickness: This is the thickness (in millimeters) of the actual display panel not including cover glass or flex cable. Module Thickness: Measured Module thickness (in millimeters) includes the entire display assembly, flex cable/ circuitry, and cover glass. 13 I Title of Presentation

Conclusions AMOLED display technology results in a significantly thinner display (Z-height) compared to LCD display technology due to the reduced number of films. The selection of a thinner display does not guarantee a thinner display module. New sub-pixel patterns are emerging. Pixel density does not necessarily drive display cost. IGZO display technologies hypothetically offer advantages in pixel density, flexible display, cost, and footprint. 21 I Title of Presentation
