Comparison between (a) LCD display with LED BLU and (b) FSC LCD display with OLED BLU.

I got this message from an anonymous source. Posting it because it sounds curious and maybe some of the tech experts reading SAR can tell us more about this technology:

SONY is working on a new display technology for its Alpha cameras after 2026’Q3.
This FSC-LCD unit will use 70% less energy and make the camera’s Live-View time much longer.

The FSC(Field Sequential Colour)-LCD, uses a high-transmittance grayscale liquid crystal display without R,G,B colour filters. It uses RGB Edge-Mini LED backlight, which means that the red, green, and blue light-emitting diodes can be switched on and off 720 times a second. This technique combines to produce a 240Hz refresh rate colour image on a grayscale 720Hz IPS LTPS LCD, delivering a flicker-free visual experience.

FSC-LCD technology is currently under development by Sony, TCL and Hisense.
TCL is planning to promote FSC-LCD televisions featuring RGB-LED backlighting in the future, and a prototype TV has been exhibited in 2025.
Sony’s BRAVIA TV business will establish a joint venture with TCL in the 2027, with both parties operating the venture jointly.
