Ambilight is therefore a technology specific to Philips which consists of surrounding the frame of its televisions with a dynamic halo of light that takes up the color codes of the image displayed. So if you watch a cartoon with predominantly pink colors, the Philips TV will restore gradient pink lighting around the set. Ambilight goes even further by restoring all the colors displayed on the screen, and this in a dynamic way. If the image is composed, for example, of alternating yellow and green, the halo will resume this alternation. This technology, invented in 2002 but appeared for the first time on the manufacturer’s 2004 range, has since become the hallmark of Philips televisions. The principle seems simple but had to be the subject of long searches materialized by patent filings. The light sources are diodes of varying intensity and colors. There are 2 types of Ambilight on the current range:

1. Ambilight Spectra 2 : The LEDs are positioned on the left and right of the television on the rear panel
2. Ambilight Spectra 3 : The LEDs are positioned on the left, on the right and above the television on the rear panel

What interest ?

Ambilight creates a better immersion in the show displayed. In the dark in particular, it creates an atmosphere that involves you even more in the horror, action or drama movie you are watching. The support wall seems to participate in the creation of the show. To dare a little excessive comparison, it’s a bit like going from a big screen to a cinema screen, it’s the same image, but it seems wider and taller, making you “fit” into the program. .

It comes out of the frame of the screen, giving the impression of freed image of its constraints and its edges. And this is all the more true as the bezels of Philips screens, like those of the competition, have shrunk over the years and with technological progress. We are purely and simply free, or at least we have the impression, of the limits of the screen size. Your television, without excessive lyricism, seems to float in the air.

The luminous halo softens the image, reducing aggressiveness, and hence eye strain. Ambilight’s halo gradient allows the eye to be less strained at all times. It reduces the contrast between the TV picture and the wall that supports the screen. Think about it, do you ever rub your eyes while watching a movie in the dark, and sometimes even get itchy? So much so that you feel compelled to turn on a lamp or a ceiling light that is reflected in the screen? Ambilight makes that feeling go away.

An accessory but very pleasant use, on the whole range, you can activate the Ambilight with the screen in standby, to create a cozy atmosphere in your interior. Dim light for a romantic tête-à-tête or to listen to a musical interlude, that can be nice, isn’t it? And as the Ambilight is generated by LEDs, power consumption remains extremely contained. Smart.

Philips is not resting on its laurels, the latest generations of Ambilight make it possible to configure and of personalize restitution according to parameters such as your wall, brightness and color dominant. To each Ambilight sound sort of …

[SOLVED] : Philips Ambilight technology: we tell you everything

How to stand out from the competition? This is the question that television manufacturers ask themselves very regularly. In fact, in general terms, all of our screens are based on a panel as large and thin as possible associated with edges as narrow as what the current state of technology allows. In addition to the regular announcement of new solutions such as Micro Dimming or, more recently, the emergence of Ultra HD, which are rapidly becoming common to all brands, it is difficult for manufacturers to offer their production a “signature”. Which sets them apart at a glance. Except for Philips with Ambilight…

If some, like Loewe, rely on the personalization of the design. Others, Samsung in particular, have turned to the curved screen. LG, for its part, has relied heavily on Oled technology. Let us pay tribute to Sony which, for its part, was the first to take an interest in sound by offering televisions with side speakers worthy of the name. Philips, finally, has opted for Ambilight, a unique device with indeed quite spectacular effects in terms of subjective contrast and magnification of the image, as long as the room where the television is located is bathed in soft semi-darkness.

A concept based on optimizing viewing comfort

However, the concept of Ambilight does not date from the last rain. Indeed, already in the 1960s, there were small blue bulbs to be housed behind the television. At the time, color television did not exist and the fluorescent coating capable of generating light under the effect of electron bombardment from black and white cathode ray tubes easily turned blue. The bluish light from the bulbs was therefore artificially “rebalancing” this dominant.

Moreover, if they remained modest in size, the screens had good brightness. The association of this light, quite violent in the dark, on a small surface therefore led to increased visual fatigue. Here again, the light from the small lamps attenuated the difference in brightness between the screen and the rest of the room, thus improving viewing comfort.

From the appearance of the first televisions, viewers felt the need to place an auxiliary light next to or better, behind the TV. Intended primarily to reduce the blue cast of the first electron tubes, it also reduces eye fatigue.

But, with the arrival of color, having blue bulbs was no longer justified. In addition, the brightness of the image provided by the first color cathode ray tubes was relatively low. Only Sony, with its Trinitron tube, stood out by offering, from its inception, a very bright image. The small blue lamps then fell into oblivion… Until 2002, when Philips offered their ultra hi-tech version for the time, namely the first Ambilight system, used two years later, in 2004, on a television set. of the brand.

Ambilight was born with fluorescent tubes

To offer more breadth to the image while improving viewing comfort, the idea of ​​the first Ambilight was to “extend” it by lighting the wall behind the television with a light of intensity and color. scalable: two parameters calculated and adjusted according to the dominant color of the image and its brightness. For this, two series of three CCFL tubes, one red, one green and one blue, were placed on the sides of the television. Remember that CCFL tubes, for Cold Cathode Fluorescent Light, are very similar to fluorescent lighting tubes. But, faster at startup, they also offer the possibility of varying their brightness in a fraction of a second. It was nevertheless necessary for them to become the keystone of the Ambilight system.

However, this was still in the early stages. Indeed, the CCFL tubes had a length identical to that of the height of the edges of the screen, therefore impossible to vary locally, in the height, color or intensity of the light emitted. Likewise, the processor responsible for determining the dominant color of the image remained fairly rudimentary. He was unable to work by image area. It is therefore the whole of the emitted light which evolves according to the dominant of the image.

The first generation of the Ambilight process was based on two triplets of CCFL tubes (neon lights) in red, green, blue, placed on each side of the TV, at the back.

Ambilight 2 a first evolution

In 2005, a first evolution took place. It concerns the processor. Indeed, if the side light sources always consist of triplets of CCFL tubes, the processor becomes capable of independently analyzing the colorimetry of the right edge and the left edge of the screen. It is thus possible to provide the television with side lighting of different intensity and color. In the years that followed, CCFL tubes gradually invaded the entire periphery of the television.

In 2006, a new triplet of red, green and blue tubes took place on the upper part of the television cabinet. Here again, each triplet is managed individually and adapts its hue, like its luminosity, according to that of the image edge it is next to. Philips then speaks of Ambilight Surround. A system followed, a short time later, by the arrival of Ambilight Full Surround. A fourth group of CCFL tubes takes place under the screen. Thus the four sides of the television can emit a light of different color and intensity.

However, the “finesse of the system” remained rather crude. Indeed, it is impossible to locally vary the tint on one edge or on the top of the image. In fact, the same edge could only take on a single color. Impossible, for example, to achieve a gradient from right to left or a specific area of ​​color in the middle of the side. A weakness that would compensate for the arrival of LEDs.
