The actual discovery of television took place when George Carey of Boston first suggested sending every component of a picture over multiple circuits in 1875. Eadweard Muybridge, captured the first photographic recordings of humans and animals in motion in 1887. This was known as Locomotion. With this ability in hand, the capturing of motion comes the concentration on visually displaying this to the world. Not long after, the Lumiere brothers created a device they called the Cinematograph, which effectively functioned as camera, a projector and printer all in one.Working with Pittsburgh’s Westinghouse Electric Corporation, a man by the name of Vladimir Zworykin, today the father of TV, invented the iconoscope in 1923. Iconoscope is a tube for transmission; it allows pictures to be electronically broken down into hundreds of thousands of elements. The iconoscope was later replaced, but six years later, Zworykin had filed a patent application for the kinescope or television receiver and demonstrated how television would work with his kinescope, or cathode-ray tube.

<br>After this a lot inventors came up with different tubes and chips and the television model was changed.

<br>The Future Is Flat, Flexible, and Fantastic! Science fiction writers of the 1960s such as Ray Bradbury and Philip K. Dick envisioned fantastic ways of using (or abusing) video images. They foresaw things like flat TV screens that take up entire walls and transparent 3D video images that bend and wrap or float in mid-air. Many of Dick's visions are currently on display in the latest sci-fi flick from Steven Spielberg, Minority Report. Organic Light-Emitting Diodes are widely regarded as the successor to LCDs due to their bright vibrant colors; full viewing angles, and low-power efficiency. The term "organic" refers to the carbon-based molecules that the technology uses in place of the metals or silicon used by other technologies such as LED and LCD. An OLED screen can be compared to a peanut butter and jelly sandwich. The peanut butter and jelly are the organic carbon-based layers and the bread is the glass or plastic substrate. OLED is similar to LCD (which is also sandwich-like), but OLED's organic materials glow when tiny electric currents are run through them, thus eliminating the backlighting that LCDs require. OLEDs have fewer process steps and also use both fewer and lower-cost materials than LCD displays. |
