Sony announces a new generation of televisions based on technology known as True RGB. This solution is set to be another step in the development of LED displays and simultaneously an attempt to reach a level that has so far been the domain of OLEDs. The manufacturer promises higher brightness, better colour reproduction, and greater control over the image than in previous designs. The new televisions will be showcased in a few weeks. It seems that at Sony's press presentation, not all its models for the upcoming year have been revealed.
What is True RGB technology?
In classic LED televisions, even those with Mini LED backlighting, light is generated indirectly. Blue diodes are most often used, and the final colour is achieved through additional layers, such as PFS or QLED, which filter the light. Sony approaches the topic differently. In True RGB technology, each diode is meant to emit a specific red, green, or blue colour without the use of filtering layers. This is a more 'physical' approach to generating colour, which eliminates losses due to light filtering. The effect? A purer spectrum of colours, greater precision, and potentially significantly better colour space coverage.
Advantage over competing RGB LED solutions
Although solutions referred to as RGB LED or Micro RGB are already appearing on the market, many of them use intermediary methods for generating colours. In practice, this means using several light sources supported by additional layers (e.g. PFS or QLED). According to information presented by Sony and industry analyses (including Vincent's materials from HDTV Test), competing technologies often do not control each “sub-diode” independently. It sometimes happens that two diodes operate simultaneously, and the target colour is only achieved after passing through the emission layer.
This leads to less precise colour reproduction, which can be observed, for example, in spectrometer measurements, where the red spectrum can appear “jagged,” and the declared coverage of BT.2020 deviates from the ideal, and the marketed 100% coverage of this palette. Sony claims their solution allows for full, individual control of each RGB, which is expected to translate into a more uniform and accurate spectrum of light.
Brightness and colour volume up to 4000 nits
One of the most interesting aspects of True RGB is the claimed brightness. Sony suggests that the new televisions may reach levels of up to around 4000 nits, which is a huge leap compared to current models; for comparison, BRAVIA 9 achieves around 1500 nits in real film scenes. Such high luminance, combined with pure colours, can significantly increase the so-called colour volume, which is the ability to maintain saturated hues at high brightness. This is one of the areas where OLEDs have previously faced limitations.
Technological foundations and experience of Sony
True RGB is not a random experiment. It is the result of many years of work by Sony on LED backlighting technologies. The company has been developing RGB systems since the QUALIA 005 model in 2004, and later introduced solutions such as Backlight Master Drive. The new technology combines experience in precise LED control with the advantages of Mini LED, while attempting to achieve picture quality associated with OLED but without its typical limitations.
New leaks about Bravia 7 II and Bravia 9 II
First leaks are also appearing online regarding specific models using True RGB technology, namely the upcoming Sony Bravia 7 II and Bravia 9 II. According to unofficial information, the TVs are expected to hit the market in a wide range of large sizes (from around 65 to even 115 inches), although the exact variants vary depending on the source. This is, of course, still just speculation, but everything suggests that the Bravia 7 and Bravia 9 series could receive a really solid upgrade if all these reports turn out to be true.
Is this a threat to OLED and QD-OLED?
On paper, True RGB looks very promising. If Sony actually achieves the claimed brightness, full coverage of wide colour gamuts, and precise control of each sub-pixel, this could be one of the biggest changes in the TV market in years. However, we will have to wait for more announcements to see if the "True RGB" TV is better than OLED.
Sony True RGB is set to be a breakthrough in display technology, moving away from light filtering towards direct emission of specific colours. This approach could provide higher brightness, better colour reproduction, and greater control over the image than previous LED systems. If the manufacturer's announcements are confirmed, the television market may face a serious shift in balance, and OLED may finally have a truly strong competitor.
