Most TVs today use LCD technology to create pictures but now there is a new emerging technology which creates even better looking pictures. This technology is called OLED. To understand how it works we have to first understand how LCD TVs works. There is a backlight at the back of a LCD TV which shines through liquid crystals. The crystals have different colored filters on the top that allow pixels to be different colors. The main difference between LCD and OLED is that OLED does not have a backlight. This allows for each individual pixel to be shut off. So, the pixels appear completely black when no current is flowing, creating very high contrast and resulting in beautiful pictures. Another quality that OLED has is the ability to create transparent displays.
