in addition to tandem OLED... Pixel aperture ratio has increased drastically since the early displays. This drops current density for a given amount of light output, and there's a nonlinear relationship between current density and segregation so that helps a ton. Deuterium helps make more light per unit current, improves current density, improves lifetime. Microlensing of your customers will accept narrower viewing angle, improves brightness and lifetime in the same way.
