OLED necessarily the same as LCD replacing CRT and replace LCD

OLED Display Module is better in terms of energy efficiency and light color lcd display module, but life is short, but the low cost, the most important is pixel high-definition display suitable, its main rival is TFT LCD. TFT display modules to backlight, OLED light-emitting materials themselves, and therefore energy consumption and brightness OLED has an overwhelming advantage, but still need to be resolved is the cost issue, OLED cost more than twice higher than the TFT-LCD,
Makes its main application only on smartphones and high-end notebook display, but as the technology matures, the yield increase, resolved to wait until the blue OLED, OLED necessarily the same as LCD replacing CRT and replace LCD.

Differences of LED and OLED

Although there are light emitting semiconductor, but there are differences between the LED and OLED structure, the main difference is:
1) OLEDs exciton with different LED's the light emitting , LED is formed by injecting electrons and holes excitons, light color depends on the composition of the semiconductor band gap; OLED form excitons by injecting electrons and holes, shock sub attenuation and light, the luminescent color depending on the fluorescence spectra of organic molecules.
2) an organic film QVGA lcd regardless of molecular size or polymer, are generally amorphous thin film (organic material by thermal evaporation, molecules evaporate at room temperature on a substrate to form a thin film supercooled state), and is a great band gap insulation membrane,the inorganic LED is ordered doped semiconductor single crystals.
3) carrier transport process in the OLED and LED are also different, the charge moves between organic molecules by the molecular ionization, such as a hole transfer in the molecule is actually neutral and positively charged molecules repeated oxidative intermolecular and restore process. The inorganic semiconductor charge transport by the band conduction.

LED backlighting, LED displays and OLED display differences in where?

LED backlighting means LCD with LED as backlight, and LED-backlit display just the traditional CCFL backlight source of a liquid crystal display Designed tube (similar to fluorescent lamps) over the LED. LCD imaging principle can be simply understood as an externally applied voltage to the liquid crystal molecules deflection just like a camel gate barrier permeability of the backlight emitted light, and then the light is projected to form an image in color filters of different colors. By controlling the LED display is a semiconductor light-emitting diode display, which is probably the way by a number of red light-emitting diodes are usually composed by the bright lights off to show character. A display screen for displaying text, graphics, images, animations, quotes, video, video signals and other information. And because the OLED display along with spontaneous, without backlighting, high contrast, thin, wide viewing angle, fast response, flexibility panel can be used, the use of wide temperature range, relatively simple structure and process of other outstanding features, are considered the next generation of flat panel display technologies emerging applications.

OLEDs have a number of advantages

Compared with the conventional liquid crystal display technology, OLEDs have a number of advantages, one of which is easy to manufacture, lower cost of the final display may be formed. OLED advantages in terms of performance, including faster response times, wider viewing angle,Lower power consumption and brightness / higher contrast images. Similar to LCD displays, OLED displays have both passive matrix and active matrix configuration. When using a passive matrix display is connected become diode grid, each diode constitutes a separate OLED pixels. You can use the external drive circuit one lit row grid. In contrast, active matrix display containing transistors, pixels can be illuminated continuously. But the difference is LCD, OLED using current drive, which increases the complexity of the active matrix design, so the vast majority of passive matrix OLED products. These PMOLED (passive matrix OLED) can be used for many products, including mobile phones, car stereos, MP3 players and other consumer products.

There are two main families of OLED

There are two main families of OLED: those based on small molecules and those employing polymers. Adding mobile ions to an OLED creates a light-emitting electrochemical cell which has a slightly different mode of operation. OLED displays can use either passive-matrix or active-matrix addressing schemes. Active-matrix OLEDs require a thin-film transistor backplane to switch each individual pixel on or off, but allow for higher resolution and larger display sizes.Low Temperature OLED display Of -40- + 80 ℃ wide operating temperature,Under ultra-low temperature faster response time,Upper unlimited viewing angle of 175 degrees.16x2 oled screen with white Character of our company,active Area with 56.22(W)mm×11.52(H)mm,viewing Area with 58.22(W)mm×13.52(H)mm
