In Hong Kong, electricity production accounts for two-thirds of greenhouse gas emissions. The Hong Kong government aims to cut carbon emissions by 50% by 2035, at which point utilities such as CLP and Hong Kong Power will need to stop using coal to generate electricity. However, the Chief Executive also mentioned in a 2021 policy report that "it is not impossible" and further said that commercial buildings need to reduce usage by 30 to 40 percent and residential buildings by 20 to 30 percent . To achieve this milestone, we had to consider all factors and reduce the power consumption of the display. The European Union has the same concern, and has revised the power consumption standards for display and lighting products.

       Roumei has a monopoly on designing new materials called quantum rods (QRs). The unique properties of these nanomaterials are higher thermal stability, high quantum efficiency in the solid state, tunable wavelengths (colors) in the full visible range, bidirectional coupling efficiency, polarized emission and low reabsorption. Therefore, these down-converting quantum rods can improve the efficiency and color saturation of modern LEDs for displays and general lighting products.
