The Sony Bravia XR-55A95K – the first QD-Oled TV on the market – has just arrived at the editorial office, and we hurried to pass this model on to the lab to answer a question: does QD-Oled technology provide a gain in brightness compared to to the classic Oled?

The Sony Bravia XR-55A95K is the first television to use the new QD-Oled panel. Manufactured by Samsung Display, this panel marks the Korean giant’s return to the OLED TV market after a failed access in 2013 (Samsung KE55S9C only lasted a month in stores). QD-OLED technology promises the best of both worlds: OLED’s infinite contrast – thanks to individual control of the illumination of each pixel – and high brightness thanks to the use of a quantum dot filter. It is a radically new technology and not just a marketing ploy. We also note that Sony does not necessarily highlight QD-Oled technology and is content to talk about Oled equipped with XR Triluminos Max and XR Oled Contrast Pro technologies.
The intense state of light, but very far from fidelity

EOTF
Light. Max. : 1050 cd / m²
In intense picture mode, the maximum brightness reaches 1050 cd / m² over a 10% window. On the other hand, in this picture mode, the luminance curve is not respected at all and the television systematically shows a picture that is too bright.
HDR Colorimetry – Intense condition
HDR colorimetry
Delta E = 16.7
The second problem with intense mode is the image quality. The color temperature is whimsical and draws far too blue, while the colors are completely wrong. We measured a delta E of 16.7, very, very far from delta E of 3, below which the colors are considered faithful. In fact, the colors are way too saturated. For example, a pale green will turn into an almost fluorescent green.
Standard mode, high brightness and slightly better colors

Light. Max. : 1040 cd / m²
In standard picture mode, the maximum brightness measured at 1040 cd / m² is slightly higher than a standard Oled TV (around 750 cd / m.). However, the picture is still very far from perfect.

Delta E = 9.1
The color temperature still pulls a little towards the blue, but everything is much better controlled than with Intense mode. On the other hand, the colors remain far from faithful, with a delta E close to 10.
Expert mode for perfect HDR, but less impressive brightness

Light. Max. : 965 cd / m²
In Expert picture mode, the maximum brightness measured at 965 cd / m² is higher than that of most Oled TVs, and even those equipped with an Oled Evo panel, such as the LG 65G1 or the latest LG 65C2 (around 800 cd / m²)). However, the Sony TV with its QD-Oled panel does not really differ from the Panasonic 65JZ2000 from 2021 with its Oled Professional Edition panel, which can reach a maximum brightness of 962 cd / m² while maintaining perfect picture quality. . The difference actually lies in the color saturation of the Sony QD-Oled model, which shows more saturated red and green primary colors, which has a visual impact with specific content.

Delta E = 2.3
As always with Sony, Expert mode makes it possible to find a simply perfect image, with colors that are very true to those sent by the source and to the director’s vision.
