OLED displays technique
Now in the second technology in the system of OLED and low molecular OLED technology for Japan, and the mobile phone calls PLEDLG polymer OEL is this system, technology and patent by British technology company, both takes compared the color in product PLED still have trouble. But low molecular OLED is relatively easy colored, samsung is released recently by the mobile phone 65530 color of OLED.
However, although more outstanding future technology of OLED TFT LCD, etc will replace the organic light emitting but still exist in the display technology using short life, and large screen. Mainly used as the OLED is listed samsung new SCH X339 - had adopted 256 colors, but is mainly OEL OLED by using in the CU8180 LG 8280 we have met.
In order to image that OLED structure, we can make a simple analogy: each unit is like a piece of OLED hamburgers, luminescence materials is caught in the middle of vegetables. Each unit of OLED display can be controlled to produce three different colors of light. OLED and LCD, also has the active and passive. Passive mode selected units by ranks address. Active mode, followed by a unit of OLED TFT (thin film transistor), driven in TFT lights. The active OLED compare save electricity, but passive OLED displays performance is better. Compared with LCD, you will find many advantages of OLED. OLED can own glow, and LCD not shine. So much brighter than the LCD OLED color, contrast, good effect. The scope of OLED nor Angle limit, can reach 160 degrees commonly perspective, nor distortion from the side. The LCD need light, light background of OLED only need to add electric lights, and unit of low voltage, so more electricity. The weight of OLED is much lighter than the LCD. OLED materials, manufacturing process is simple, seldom producing cost less than 20% to save LCD. But now the main drawback is OLED than LCD, short life, only 50 hours can reach 10000 hours LCD.
