“…The key of this approach is the material employed. The use of polymers [76], as well as graphene [77], seems very promising in terms of consumption. There are prototypes of different technologies and sizes, from a large plasma display [78] to a small AMOLED module [79] passing through the Mobius Display by E-ink [80], which maintains the power consumption levels of other e-ink displays.…”

This paper provides an overview of the main manufacturing technologies of displays, focusing on those with low and ultra-low levels of power consumption, which make them suitable for current societal needs. Considering the typified value obtained from the manufacturer's specifications, four technologies-Liquid Crystal Displays, electronic paper, Organic Light-Emitting Display and Electroluminescent Displays-were selected in a first iteration. For each of them, several features, including size and brightness, were assessed in order to ascertain possible proportional relationships with the rate of consumption. To normalize the comparison between different display types, relative units such as the surface power density and the display frontal intensity efficiency were proposed. Organic light-emitting display had the best results in terms of power density for small display sizes. For larger sizes, it performs less satisfactorily than Liquid Crystal Displays in terms of energy efficiency.

“…6,7 However, the brittle nature of ITO might limit its role in future devices. 8 For instance, 150 nm-thick amorphous-ITO (a-ITO) films or 100 nm-thick crystalline-ITO (c-ITO) mounted on a plastic film (thickness: 100 μm) would crack with a bending radius of o3 mm. 9,10 In addition, the poor thermal stability of optical-grade plastic films -such as polyethylene naphthalate-precludes the use of c-ITO that requires a high-temperature processing step above 250°C that most optical plastic films cannot stand.…”

Here, we propose crystalline indium tin oxide/metal nanowire composite electrode (c-ITO/metal NW-GFRHybrimer) films as a robust platform for flexible optoelectronic devices. A very thin c-ITO overcoating layer was introduced to the surface-embedded metal nanowire (NW) network. The c-ITO/metal NW-GFRHybrimer films exhibited outstanding mechanical flexibility, excellent optoelectrical properties and thermal/chemical robustness. Highly flexible and efficient metal halide perovskite solar cells were fabricated on the films. The devices on the c-ITO/AgNW-and c-ITO/CuNW-GFRHybrimer films exhibited power conversion efficiency values of 14.15% and 12.95%, respectively. A synergetic combination of the thin c-ITO layer and the metal NW mesh transparent conducting electrode will be beneficial for use in flexible optoelectronic applications.

“…Flexible electronic devices including displays and photovoltaic cells are currently being developed using polymer substrates [1][2][3][4]. Such devices present advantages, such as conformability and light weight, and are potentially compatible with cost-effective roll-to-roll (R2R) production processes [5].…”

Influences of roll-to-roll process and polymer substrate anisotropies on the tensile failure of thin oxide films

et al. 2010

The influence of internal stress anisotropy resulting from anisotropic loading in a roll-to-roll (R2R) process, and polymer substrate anisotropy on the crack onset strain (COS) of thin oxide coatings was analyzed. Experimental data obtained for R2R processed films were compared with data obtained using an isotropic sheet-to-sheet (S2S) process with the same anisotropic substrate. In the R2R case the COS was found to increase by 20% between the transverse direction and the machine direction. In the S2S case the COS was found to be independent of orientation, except at a 45°in-plane orientation with respect to the machine direction, where it was 15% higher. The internal stress in the machine direction could not be determined, presumably due to deposition-induced curvature changes of the polymer substrate, and was therefore fitted to the COS data. Fracture mechanics analysis and finite element modeling of the experimental data showed that the influence of substrate anisotropy was marginal, and that it was the process-induced internal strain in the coating which controlled the COS.
