Photos were taken with a Canon PowerShot A470 digital camera using "Super Macro" mode and 4.0× digital zoom. The screen used was that integrated into a Lenovo G550 laptop. Note that the display has RGB pixels. Displays exist in all four patterns horizontal RGB/BGR and vertical RGB/BGR but horizontal RGB is the most common. In addition, several colour subpixel patterns have been developed specifically to take advantage of subpixel rendering. The best known of these is the PenTile matrix family of patterns.

Famous quotes containing the word examples:
“It is hardly to be believed how spiritual reflections when mixed with a little physics can hold people’s attention and give them a livelier idea of God than do the often ill-applied examples of his wrath.”
—G.C. (Georg Christoph)
“In the examples that I here bring in of what I have [read], heard, done or said, I have refrained from daring to alter even the smallest and most indifferent circumstances. My conscience falsifies not an iota; for my knowledge I cannot answer.”
—Michel de Montaigne (1533–1592)
“Histories are more full of examples of the fidelity of dogs than of friends.”
—Alexander Pope (1688–1744)
