Sony has announced that it has developed a new rear lighting system that can ground in television technology. This system, which the company calls the company “General RGB LED Back Lighting Technology, enables red, green and blue LEDs to work independently in each rear lighting zone. Compared to the existing mini LED TVs, this technology can increase color accuracy and offer wider monitoring angles without sacrificing brightness. In a presentation at the Sony headquarters in Tokyo, the difference of this new system was revealed.
Today, mini LED TVs work with small blue LEDs placed behind the screen. This structure can precisely adjust the brightness of certain areas of the screen. On the other hand, OLED TVs offer excellent contrast thanks to their independent lighting ability, but they cannot be as big or bright as mini LEDs. Sony’s new RGB LED technology can optimize the color accuracy and brightness at the same time by placing three different colors LEDs in each rear lighting zone.
Sony says that this system can reach a brightness of 4000 cd/m². This value is at the same level as the company’s professional reference monitors and provides the highest color volume offered on commercial television. Thanks to advanced color transitions and wider monitoring angles, a more natural and accurate image can be achieved than mini LEDs. In addition, the production of larger sizes from OLED screens stands out as an important advantage.
A special prototype was displayed in the screening of Sony’s center in Tokyo, revealing the difference of RGB LED technology. First, using a LCD panel covering only half of the screen, showing how sensitive the backlight works. On the stage where a bus progresses on a sunny street, it is possible to distinguish different shades of red by using only back lighting.
Later, a full-screen prototype with RGB LED Backlight was tested side by side with Sony’s top-upstone Bravia 9 and QD-OLED A95L, the mini LED-supported models. In the screening, a scene from the Frozen film was used. Although Bravia 9 appeared almost monochrome in the Bravia 9, the RGB LED prototype was able to successfully show deep purple tones. Thanks to this technology, color saturation and monitoring angles significantly improve, while the “Blooming” effect (light leakage around bright areas), which is frequently seen on mini LED screens, has decreased significantly.
However, it is still not possible to reach the perfect black levels that OLED offers. Especially in a dark scene, a red light source was shown, the RGB LED system could still be seen a slight color leakage. However, on the OLED screens, a slight turbidity can be detected around the bright spots due to the optical scattering (retinal straylight) caused by the human eye. Sony’s new technology seems to have managed to minimize the artificial light spread in Mini LEDs by coloring for the stage.
The idea of RGB LED back lighting is not a completely new technology. In 2004, Sony used this method in the high -cost Qualia series and exhibited a prototype called “Crystal LED ında at CES exhibition in 2012. Competing brands are working on similar systems. Hisense introduces the “Trichroma RGB Back Lighting” Mini LED TV on Ces this year, while TCL and Samsung are developing models with similar technologies.
Daisuke Nezu, Sony’s home cinema systems unit manager, states that they expect these developments in the sector. Sony rely on the experience of back lighting technologies and image signal processing. Mara Redican, the representative of the company, emphasizes that Sony’s knowledge in this field cannot be easily imitated by saying, “We believe that we can provide reliability and determination, not only offering high image quality, but also reliability and determination.
Sony’s RGB LED back lighting technology is capable of competing even with the company’s best available televisions. Especially in terms of brightness, the A95L model leaving behind, color accuracy and monitoring angles in terms of OLED’s advantages are difficult to catch. Although the lighting feature on the basis of deep blacks and pixels offered by OLED technology is still one step ahead, the high brightness of the RGB LED and its large screen production flexibility can be an attractive alternative for consumers.
Will Sony OLED withdraw from the TV market?
Although Sony does not give any signal to withdraw from the OLED TV market, it aims to provide consumers more options by offering wide -screen and high brightness alternatives. This new technology can be an important alternative, especially for those looking for a model that can be used in large rooms with 100 inch or larger display sizes. With the integration of RGB LED panels into commercial models, a more advanced image experience is expected to be offered compared to mini LED TVs.
