42.3: Invited Paper: Color Passive‐Matrix Organic LED Display using Three Emitters

Abstract

We developed 2.2-inch diagonal (132 x RGB x 162 pixels) Color Passive-matrix Organic light emitting diode(OLED)Display through the use of patterned lateral RGB emitters, and started the pilot production. That display is thin (2.5mm, The driver circuit is included.) and light (10g, The driver circuit is included.), and has a wide range of viewing angles. That is proven to be practical for commercial purposes.

“…4d). Thanks to this superior patterning capability of the SI-OLES, furthermore, the full-color SI-OLED array corresponding to 949 ppi was successfully achieved, exhibiting the highest resolution compared to the reported full-color OLED arrays via various OLED patterning methods [45][46][47][48][49][50][51][52][53][54][55] (Fig. 4e, f and Supplementary Fig.…”

Integration of organic light-emitting diode and organic transistor via a tandem structure

“…Fortunately, the lifetime issue can be resolved using the active matrix ͑AM͒ scheme in which a thin-film transistor combined with a capacitor, is applied to function as a switch for each OLED. [8][9][10] In turn, the AM scheme not only allows high information content display, but also provides low power consumption, high brightness, and improved gray scale capability. Generally, amorphous or polycrystalline silicon 11 have been the choice of material for the thin-film transistor in order to achieve a high filling factor and low stress direction for light emission.…”
