Display
The central feature of the Optimus 3D is its 4.3-inch 3D LCD screen, which set it apart in the smartphone market. This display, with a resolution of 480 x 800 pixels and a density of approximately 217 ppi, provided users with the novel experience of glasses-free 3D viewing. Although the technology was fascinating at its release, the execution was a mixed bag; the 3D effect could be strenuous for the eyes over extended periods, and content available for 3D viewing was limited. Nevertheless, the LG 3D UI enhanced the user interface, allowing for some interactive 3D content that captivated those keen to experiment with new technology.
