Lab – Sony A95K QD-Oled TV: Which Brightness Tip for the First QD-Oled TV?

4

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.

Editor's rating: 5 out of 5

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.

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.

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.

Light. Max. : 965 cd / m²

Editor's rating: 4 out of 5

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.
