tuhin4u (Unstopable Lover + Mariana World DIAMOND member): In contrast to a conventional OLED, in which the anode is placed on the substrate, an Inverted OLED uses a bottom cathode that can be connected to the drain end of an n-channel TFT especially for the low cost amorphous silicon TFT backplane useful in the manufacturing of AMOLED displays. * 05-10-14 - 05:32:23
tuhin4u (Unstopable Lover + Mariana World DIAMOND member): Conventional OLED displays are formed by vapor thermal evaporation (VTE) and are patterned by shadow-mask. A mechanical mask has openings allowing the vapor to pass only on the desired location. * 05-10-14 - 05:33:17
tuhin4u (Unstopable Lover + Mariana World DIAMOND member): For a high resolution display like a TV, a TFT backplane is necessary to drive the pixels correctly. Currently, low temperature polycrystalline silicon (LTPS) – thin-film transistor (TFT) is used for commercial AMOLED displays. LTPS-TFT has variation of the performance in a display, so various compensation circuits have been reported. * 05-10-14 - 05:34:19
tuhin4u (Unstopable Lover + Mariana World DIAMOND member): Due to the size limitation of the excimer laser used for LTPS, the AMOLED size was limited. To cope with the hurdle related to the panel size, amorphous- silicon/microcrystalline-silicon backplanes have been reported with large display prototype demonstrations. * 05-10-14 - 05:35:04
tuhin4u (Unstopable Lover + Mariana World DIAMOND member): OLED displays can be fabricated on flexible plastic substrates leading to the possible fabrication of flexible organic light- emitting diodes for other new applications, such as roll-up displays embedded in fabrics 0r clothing. As the substrate used can be flexible such as polyethylene terephthalate (PET), the displays may be produced inexpensively. Further, plastic substrates are shatter resistant, unlike glass displays used in LCD devices. * 05-10-14 - 05:36:41
