3DTVs are beginning to flood the market, Panasonic will be flogging 3DTVs in the US by month’s end and Sony will be following behind with a launch date in June. The LX900, HX900 and HX800 look great. The competition is on between Sony and Panasonic, Japan will start sales of the 3DTV set on June 10th and world wide soon after. But Sony is claiming that they will be cheaper than Panasonic’s 3DTV.

Akihabara News was in attendance at a press launch of the LX900, HX900 and HX800 3D sets in Japan, which are all of the “monolithic” design. Based on their reviews the LX900 series consists of four models all with Intelligent People Sensors which allows you to adjust the sound and brightness as to where the viewer is located. It was built on the VE5 TVs launched last year which can also detect when you leave the room and turns off automatically.

The LX900 will be available in 40, 46, 52 and 60-inch LED-backlit options, will have inbuilt wireless LAN, and include two sets of 3D active shutter glasses (which will be available in grey, blue and pink options). The 46-inch size will reportedly cost 350,000 Yen—about $3,900. Only 46 and 52-inch options will be available for the HX900 series, which will be LED-backlit, and feature Intelligent MPEG noise reduction. Less attractive, the HX800 lacks the Intelligent People Sensors and MPEG noise reduction, and come in just 40 and 46-inch sizes.

These are all LED-backlit LCD panels, refreshingly at no more than 3ms, whereas plasmas are better suited to showing 3D because of their smoother and faster images.

Here’s all you need to know in more details:

LX900 series

The flagship LX900 series consists of four models with screen sizes between 40 ($3,200), 42 ($3,900), 50 ($4,800) and 60 inches ($6,500). Buyers will get 2 pairs of active shutter glasses, wireless LAN, full HD, 4 HDMI ports, a USB port, video-on demand, and LED backlight. The 60-inch model, the KDL-60LX900, is pictured above.

There’s also an “intelligent people sensor system”, which adjusts images and sound depending on where viewers are located. And through face detection, the TVs can even be “personalized”. For example, the TVs can detect if a child is sitting too close to the screen and display a warning message. And if nobody is in the room for a certain period of time, the TVs shut down automatically (“On/Off Conscious” function).

The 40- and 42-inch models will go on sale in Japan on June 10, followed by the bigger LX900 models on July 16.

HX900

The HX900 series consists of a 46- ($4,350) and a 52-inch ($5,250) model. For some odd reason, 3D glasses are not included in the price. These models are full HD, too. The HX900 series shares main specs with the KX900 (outlined above) but lacks the fancy sensor systems and wireless LAN. The bigger of the two models, the KDL-52HX900, is pictured above.

Both HX900 models go on sale on July 16.

HX800

Priced at $2,450 for the 40-inch model and $3,100 for 46-incher, the two models of the HX800 are the cheapest of all 3D TVs Sony unveiled today. The TVs feature LED backlights, full HD and all basic specs of the HX900 but come without wireless LAN or sensors. They also lack the 3D glasses, which buyers need to get separately. The picture above shows the 40-inch model, the KDL-40HX800.

The two HX800 TVs are scheduled to hit Japanese stores on July 16.

Sony wireless LAN adapter

The HX800 and HX900 TVs do have (wired) LAN but buyers can also get the UWA-BR100, a wireless LAN adapter that’s to be inserted into the USB port of the TVs. It’s already available in the US for $79.99.

Sony Active Shutter 3D TV glasses and synchro transmitters

As the HX900 and HX800 TVs don’t come with glasses, Sony also announced the extra-large TDG-BR100 in black and the smaller TDG-BR50 in blue or pink (price: $140 each) today. Then there’s TMR-BR100, a 3D “synchro transmitter”, which makes sure the glasses can actually display the 3D images your TV produces (price: an extra $60).

Sony said they will roll out these TVs globally at around the same time, meaning Panasonic will have a head start of about 3 months in the USA and 2 months in Japan. Just like Panasonic, Sony is expecting the 3D business to evolve into an important revenue machine in the near future.
