* 1876 - George Carey created selenium described camera can make a person see a wave of electricity. Later, Eugen Goldstein calls the shot in the light waves that vacuum tube called a cathode ray.

* 1884 - Paul Nipkov, German scientist, managed to send an electronic image using a piece of metal called a telescope with a resolution of 18 electrical lines.

* 1888 - Freidrich Reinitzeer, Austria botanist, discovered liquid crystals (liquid crystals), which later became the LCD manufacturing raw materials. But the new LCD screen was developed as 60 years later.

* 1929 - Russia's Vladimir Zworykin perfected the cathode tube called a kinescope. Findings to develop technology owned CRT.


* 1940 - Peter Goldmark create color television with 343 lines of resolution achieved.

* 1958 - The first scientific paper on the LCD as a display presented Dr. Glenn Brown.

* 1964 - The prototype of a single cell display was first invented Plasma Television Donald Bitzer and Gene Slottow. This step is followed Larry Weber.

* 1967 - James Fergason discovered a technique twisted nematic, the LCD screen is more practical.
