Advanced  --mobile phone technology Samsung YOUM The key technologies: 1. Software Radio Technology 2. 3D display technology of the mobile terminal 3. Mobile single-chip 4. Transparent OLED technology 5. AMOLED Technology OLED Display 1.Passive Matrix (PMOLED) 2.Active Matrix (AMOLED) For each pixel, the electron current flows from the cathode to the anode，while the so called hole current flows in the reverse way．Electron-Hole recombination releases photons in the organic emission material layer. This shows that the light is directly proportional to current．Making OLED display current driven devices． OLED Structure AMOLED Advantages 1.Compared to traditional LCD, AMOLED screen is very thin and can be integrated touch screen layer, an advantage for the ultra-thin machine. 2.AMOLED has a certain degree of flexibility, compared to the glass substrate of the LCD screen should not be damaged. Different from LCD which, in principle, needs two glass panels, AMOLED needs not upper glass panel if the organic materials and metal cathode layer in OLED device are protected from environmental water vapors or other gases. The single glass device gives many unique characteristics to AMOLED. Owing to these characteristics, paper-thin and bendable card display or foldable display can be realized. 3. High resolution AMOLED with pentile arrangement, different from traditional LCD as a pixel is equal to the collection of three sub-pixel ,include red, green and blue, for AMOLED, one pixel equal to one green, 0.5 (blue and red), a substantial emphasis on green, make the picture look more vivid. AMOLED Weaknesses 1.Pentile, with this arrangement, the resolution is less than the nominal 70%, in the case of a lower dpi, grainy will obvious , re-close look can clearly see the color point and the edge of the text made ??virtual. 2.The AMOLED stressed green, which can cause its too bright effect. 3. AMOLED is self-luminou
