Organic Light Emitting Diodes (OLED) is the newest display technology gradually changing the future of electronics around the world. OLED televisions are already giving a challenge to the current LCD and plasma TVs. They are brighter, thinner, and more efficient with better refresh rates and contrast.
A series of thin films is placed between the two conductors to make OLED televisions. A bright light is emitted by the OLED materials when electrical current is applied. Each pixel can be addressed individually thus controlling the patterns of light and colour which combine to form a picture through this semiconductor technology. Therefore a separate backlight is not essential. This is the most important selling point for the OLED technology as backlight accounts for the maximum power consumption. Thus OLED televisions can operate at very low current supply of only 2-10 volts.
Due to OLED technology display panels are very thin (0.5 thousandths of a millimetre thick). These thin displays have a wide viewing angle of up to 170 degrees. OLED television display panels can be made very flexible and transparent. Who knows if cylindrical OLED displays which can be folded when not in use are the future of the television technology?
