  • It provides us with a full HD image plus a small additional space so as to not superimpose controls or action buttons on the images, provided we work on a computer.
  • Manual focus and zoom adjustments, but far from being an inconvenience, we see it as an advantage.
  • The useful life of the lamp is expected to be 20,000 hours. Sounds good, doesn’t it? And if we translate that into 8 hours per day 5 days a week, it gives us a useful life of about 10 years! Even better!

 

Designed for environments where visibility with ambient light is decisive. Its laser illumination source offers us all the light we could ever need.

Keep calm. The light source is a laser that projects images through a DLP chip butit doesn’t mean that we are literally going to lithograph the walls or our screen even. However, one of the objectives Panasonic set when conceiving this product was being able to visualise clear and perfectly visible images, even if we are in a bright room with all the shutters open and the sun pouring in.

Nowadays, we have a wide range of projectors conceived for home cinemas, and they are all designed to offer the most enjoyable viewing experience possible in controlled illumination environments, generally very low, the same as in movie theatres. But when our needs are different and what we need is a sharp and contrasted projection in environments with quite a bit of ambient light, like meeting rooms, training centres, public open spaces, etc., we inevitably need to resort to other products.

 

Here is where the star we are analysing in this laboratory shines brightly. A bright star thanks to its 5,200 lumen offered by its illumination source and that, of course, is also capable of offering an agreeable cinema experience for two very significant reasons: the ambient light sensor, capable of controlling the power according to the illumination of the hall; and its colour space, which can be configured in different modes, including REC709, which we shall dedicate some time to further down.

 

The native resolution of the DLP (Digital Light Processing) chip is WUXGA, slightly above HD, offering 1920 x1200 pixels, according to the 16:10 format and the resolutions of many graphic cards and current computer screens. This provides us with a full HD image plus a small additional space so as to not superimpose controls or action buttons on the images, provided we work on a computer. As regards HD, the maximum frame frequency supported is 60p, more than sufficient.

Regarding the image, we find a couple of aspects to highlight. Images are not only built with brightness and resolution. The single chip DLP image systems require a chromatic range that is critical when reproducing colour. In our case, it is a range consisting of 4 segments that offers a broad range of colours and enables, among other aspects, to offer a balance between the whites and improved reproduction of colour compared to other devices, despite them being based on the same technology. All this combined with the image processor permits configuring different colour spaces that offer different reproduction options, infrequent until now, in addition to an option to reduce noise that enables improving the images that could become degraded.

 

In fact, we can configure different colour profiles, through which we will produce even brighter, more contrasted and saturated images, or with extended colour spaces, like the RC709 mentioned above (standard for cinema and wide spectrum video reproduction), and even the DICOM, which has the most specific requirements for the visualisation of medical images in Radio-diagnosis system. In all these situations, the ambient light sensor permits keeping optimum visualisation even when the ambient light changes during projection.
