A smartphone's tiny screen relies on the strange properties of liquid crystals. Check out Groupon's study of LCDs to learn how they create the vivid pictures in your pocket.
The term liquid crystal seems a contradiction, but a liquid crystal is actually neither a liquid nor a solid?it's both, stuck in a sort of chemical limbo with its molecules somewhere between the liquid and solid phases. When an electrical current passes through a liquid crystal, its molecular orientation changes, and so does the direction of light that passes through it. By sandwiching these crystals between polarized glass and manipulating the current passing through them, your phone is able to control the light they channel, resulting in the high-contrast images that appear on screen. Although our brains only see each pixel as a single dot, each consists of red, blue, and green subpixels that, when lit at various intensities, can emit more than 16 million colors.
Despite their advanced applications, liquid crystals are not a recent discovery. They were first identified in the late 19th century by a scientist studying cholesterol extracted from carrots?a natural source of liquid crystals, as are human beings and most other living things, which tend to have them in their cell membranes. Liquid crystals and LCDs were the subject of research and patent applications throughout the early 20th century?including one filed by Marconi?s Wireless Telegraph Company in 1936?and finally hit consumer electronics in the early 1970s, when they were introduced in wristwatches.
El Paso transplants John Dorgan and Conrad Bejarano founded I Luv Video in 1984, and unlike corporate movie-rental stores, their independent store is still thriving. That's because it celebrates classic, indie, and hard-to-find movies, offering patrons an extensive selection of films across a variety of formats.
Unlike watching streaming movies on demand, I Luv Video brings movie lovers together in a real-life social environment, treating visitors to special events such as Cinemondays film screenings, Free Beer Tuesdays, and Spot the Baguette in the French Film Friday. Guests can also chat with fellow film buffs or knowledgable staffers as they browse an ever-growing selection of cult films, underground hits, and big-name titles, all easily pinpointed through the store's online search function. Additionally, the store attracts patrons with its rare vintage toys, movie memorabilia, and films.
Bearing the titles of Master of Photography and Photographic Craftsman from Professional Photographers of America, David and Ally McKay embody the keen vision and aesthetic prowess that separated good photographers from great ones. They share these skills during classes at McKay Photography Academy, where they train eyes, fingers, and imaginations to work in tandem as a snapshooting dream machine. Their classes help aspiring photographers progress from neophytes to seasoned pros. When not busy instructing the next generation of shutterbugs, David and Ally also devise photo safaris, which send small teams of photographers to capture shots of famed landmarks including San Francisco's Golden Gate Bridge; the Lincoln Memorial of Washington, DC; or Yosemite's 60-foot statue of Yogi Bear.
