Today we are going to talk about  OLED Display.  Hope you like it! Introduction About OLED Display OLED (Organic Light Emitting Diodes) is a flat light emitting technology, made by placing a series of organic thin films between two conductors. When electrical current is applied, a bright light is emitted. OLEDs can be used to make displays and lighting, because OLEDs emit light they do not require a backlight and so are thinner and more efficient than LCD displays (which do require a white backlight). And OLEDs are used to create digital displays in devices such as television screens, computer monitors, portable systems such as mobile phones, handheld game consoles and PDAs. Before moving to our classroom i would like to introduce about  AMOLED  and  OLED 1) AMOLED Display: AMOLED stands for Active Matrix Organic Light Emitting Diode. A step ahead of OLED screens, the AMOLED screens can control each pixel individuality while maintaining the properties of an OLED...

The History Of The Mobile Phones watch video of mobile evolutions Although most of us feel like we couldn’t live without our mobile phones, they’ve not really been in existence for very long. In fact, mobile phones as we know them today have only been around in the last 20 years. WHEN WERE MOBILE PHONES FIRST INVENTED? Mobile phones, particularly the smartphones that have become our inseparable companions today, are relatively new. However, the history of mobile phones goes back to 1908 when a US Patent was issued in Kentucky for a wireless telephone. Mobile phones were invented as early as the 1940s when engineers working at AT&T developed cells for mobile phone base stations. The very  first mobile phones  were not really mobile phones at all. They were two-way radios that allowed people like taxi drivers and the emergency services to communicate. Instead of relying on base stations with separate cells (and the signal being passed from one cell to another), the firs...
