Sony and TCL Preparing the Ultimate Television Without Color Filters: Farewell to Traditional Mini LED
The launch of this Sino-Japanese alliance seems powerful.
The new alliance between Sony and TCL is showing much more than we expected. A new joint venture called Bravia Inc. has found a way to manufacture a completely new and innovative type of panel, which is neither LCD nor OLED. This means that Mini LED televisions (and almost all traditional LCDs) could be discontinued in the form we know them.
TCL's display factory (CSOT) and its giant competitor AUO are both actively involved in developing Field Sequential Color (FSC-LCD) panels. This technology aims to completely eliminate passive color filters, which have been the biggest bottleneck for traditional LCDs, QLEDs, and Mini LED televisions.
Finally, the color filter, the weakest point of LCD, Mini LED, and LED panels, is gone.
Until now, the television panels we could buy were only LCD (with hundreds of subtypes depending on the elements added to the panel, such as QLED, LED, Mini LED, RGB Mini LED) and OLED (with two subcategories: WOLED and QD-OLED). However, the new research led by Sony and TCL seems poised to replace old LCD panels with a completely new type.
In all existing LCD televisions, white light generated by the backlight system has to pass through a color filter matrix (red, green, blue) to create the basic colors of the video. This process results in significant brightness loss. This is a problem that Sony, for example, addressed with the introduction of RGB Mini LED.
But now they are going further, making it more efficient and easier to manufacture. They have significantly improved light control capabilities through a new system entirely different from RGB Mini LED, achieving a level of control close to 1 pixel. Yes, like OLED televisions.
The new LCD-FSC display seems to be the ideal solution: OLED's blacks and perfect colors.
The new FSC panels are based on the working principle of single-chip RGB laser DLP projectors. In FSC-LCD panels, the physical color filters of the pixels are completely removed, leaving only a matrix that works in grayscale (shades) to control the brightness of each pixel. Color images are formed by the ultra-fast sequential flashing of red, green, and blue light from the basic RGB backlight.
Because of how our brains work, our brain fuses these bursts (sequential emission of R, G, B light) into a single full-color image. To prevent perceptible flickering and visual artifacts (the rainbow effect often avoided in projectors), the industry proposes operating at a base refresh rate of 240Hz, forcing the backlight to perform 720 color transitions per second (240 times for each RGB channel).
The creation born from the research jointly conducted by Sony and TCL brings together a masterpiece. The combination of being able to control light almost at the pixel level and the ability to emit the purest possible RGB colors will allow us to create the ultimate television.
Anyway, this new development seems to have originated from an initiative to create a screen that most faithfully mimics Sony's new Alpha camera Preview (scheduled for release in Q3 2026). Removing traditional color filters from the flip-out screen and electronic viewfinder of professional cameras allows for fundamentally brighter visualization and superior contrast ratio when direct sunlight is shining. This technology could be transplanted into future televisions in the not-too-distant future.
