BOE shows new OLED displays at SID Displayweek 2024

BOE had a large demonstration at Displayweek 2024, showing several display technologies and many new panels and prototypes.

First up we have a slidable OLED display, one of the largest we've seen, at 31.6". The display offers a resolution of 5944x1672, a sliding distance of just over 260 mm (BOE says its the world's longest) and a sliding radius of 5 mm.


The second display was a 13.2" 2880x1920 600 nits notebook OLED display, produced on an oxide TFT backplane. The mobility of BOE's oxide TFT is ~40 cm2/V. BOE says that this panel has an internal compensation circuit.

BOE had several automotive displays on show, including an automotive-grade 15.05" 2560x1600 flexible OLED display (BOE calls its an L-Shaped display), that offers a brightness of 800 nits, a bending radius of 35 mm and a wide operating temperature range (-30 to 85 Degrees Celsius). BOE also demonstrated another automotive display, that combines a 17" (2972x1672) curved (400 mm curvature radius) and a 15" (2560x1600) foldable (5 mm folding radius) display to create one large display, saying that this is the industry's first commercial foldable automotive display.

During the show, BOE demonstrated two technologies used to reduce the power consumption of its OLEDs. The first is the Hybrid-Refresh Rate OLED technology that enables different refresh rates in different regions of an LTPO OLED display. The technology offers 1-120Hz refresh rates, and according to BOE can reach up to 18.6% in energy saving (at 500 nits). The second technology is an OLED architecture in which each sub pixel (red, green and blue) is driven with a separate power supply, and can be applied a different voltage. BOE demonstrated a smartphone display that uses this technology, which enables a power reduction of around 5-6% (at 500 nits).

BOE also demonstrated two  OLED microdisplays. First up was the 1.35" 4K 90Hz display we have already seen, that is based on a white OLED design with color filters. The second display was more interesting - a 0.5" display that has a side-by-side architecture, real RGB subpixels without filters. The display offers a resolution of 1600x1200 (4032 PPI), and a brightness of 5,000 nits. BOE says that it also offers very low power consumption. The company did not detail how close it is to commercialize such a display.

Finally, BOE also showed a microLED display demonstrator, that included two panels that can connect in an almost seamless way (but not completely). The curved displays have a 0.3 mm pitch display (P0.3), a brightness of up to 2,000 nits (peak), and a refresh rate of 90Hz.
