Researchers develop polarized LCD backlighting unit based on semipolar microLEDs and perovskite materials
Researchers from several Universities in China developed a self-polarizing RGB device utilizing semipolar microLEDs and perovskite based films aimed at improving backlight applications.

In standard LCD displays, the backlighting units emits non-polarized light, which then results in an almost 50% light loss as this light has to pass through a polarizer (this is part of the LCD light path). The newly developed high-performance device is designed to emit RGB polarized light which results in higher efficiency and no light-loss due to the LCD filter.
Digitimes Research: smartphone makers to adopt mini-LED backlit LCDs as an alternative to AMOLEDs in 2018
Digitimes Research says that China-based smartphone makers (including Huawei, Oppo and Xiaomi) are planning to adopt mini LED backlit LCD panels in future smartphones as an alternative for AMOLED displays.
The Chinese phone makers have reached out to Taiwan-based LED makers to start making mini-LED backlighting units by June 2018. Currently the OLED market is in an over-demand situation which means that securing enough AMOLED capacity is not easy - and it also drives prices up. According to IHS, the situation will reverse in 2018, though.
