Philips unveils 3rd generation P5 Processor for 804 and 854 OLEDs

3rd generation P5 chips from Philips up the ante

  • New image processing techniques are regularly introduced to improve TV pictures. The CPUs that drive these processes can often be a crucial selling point of the TV, so Philips is keen to point out the virtues of their latest, 3rd generation, P5 chip.
    Much is made of the CPUs at the centre of the very latest TVs and the power imparted to the processing engines they drive. Philips has already made a notable impact with last year’s version of their P5 chip - winning, as it did, the AVForums Best Picture Processing 2018 Award whilst residing at the heart of the Philips OLED903.

    2019 sees a new, 3rd generation, iteration of the P5 chip for use in Philips’ new OLED TVs, the 804 and the 854. This latest version adds additional computational power to key parts of the processing chain to produce a 20% PQ improvement over last year’s 2nd gen chip.

    A key development is the inclusion of Dolby Vision in the P5 chips, which allows Philips to offer all current forms of HDR functionality - HDR10, HDR10+, Dolby Vision & HLG - across the entire TV range, from the new OLED sets to the latest 6000 Series. This benefits the consumers by allowing them access to all HDR sources, whether disc based or via streaming services, without forcing them to choose between competing formats.

    The Philips TV PQ team has worked in partnership with Dolby to enable the key benefits of P5 to deliver a viewing experience that retains original artistic intent. Dolby Vision improves brightness, contrast, detail, and colour and, when compared to a standard picture, the result can be brighter highlights and darker blacks. The result is a more lifelike image and, because the process is dynamic, it can make these improvements on a scene by scene basis rather than creating one effect for the whole movie.

    Similarly, the P5 can process HDR10+ dynamic HDR metadata and can produce images with less noise and artefacts. For HDR content, the 3rd gen P5 improves the image by reducing the loss of detail in very dark areas and any colour clipping in very bright and colourful scenes. It also decreases unwanted banding or gradients on skin tones.

    Noise reduction has always been a key goal for Philips and the means to improve this is built into the P5’s processing suite which enables the maximum reduction of noise but without introducing detail blurring or smearing.

    In addition, the 3rd generation P5 brings improved sharpness and contrast to all sources. Philips Perfect Natural Reality image processing feature reaps some new benefits and the result is a more realistic image which creates more depth impression and helps to transform SDR content into an HDR-like picture.

    For sharpness performance, the original P5’s Detail Enhancer feature has been further improved by adding a Detail Protection and Restoration function to attain better results when transforming the original pixels into sharper pixels. A new Dejaggy filter is also applied to low and high angle diagonal lines. The result is a cleaner image with finer lines.

    Other improvements add de-contour enhancement, bit-depth calculation and sparse filtering to produce an even cleaner, sharper image.

    The original Philips TV P5 engine was designed to analyse and individually address each of the 'Five Pillars' that together define overall picture quality: Source perfection, Sharpness, Colour, Contrast and Motion. The 3rd generation P5 carries on that tradition by providing the necessary power the processing engine requires to drive the new Philips TVs for 2019.

    Could an AVForums award be waiting for the P5 this year too? Over to the competition…...
