The chassis design revolves around the video processing circuits located on the BAL board. The key difference between models is determined by the size of the LCD panel and its manufacturing source. This manual will describe the new circuit features and individually describe the models based on these differences.

Features

Several new features are introduced in the EX-M chassis model lineup along with some carryovers from the previous year.

720p Panel

The EX308 models incorporate a native 1366 X 768 (WXGA) resolution panel. All video signals exit the video process circuits as 720p 60HZ. The RGB resolution is 8-bit to provide 256 levels of gray scale.

CCFL Backlighting

Many of the 2010 Sony television models are introducing edge-lit LED backlighting. The EX308 series incorporates traditional cold-cathode fluorescent lamps (CCFL) to generate the necessary backlighting for the LCD panel. A self contained (direct) inverter circuit supplies the necessary high voltage to drive the backlight lamps.

Wireless Internet Ready

An optional wireless network adapter is available to connect the television to a home network. These models have an Ethernet port on the rear for direct connection to the home network. Plugging the optional wireless network adapter into the USB2.0 port on the side of the television allows for wireless connectivity when conditions do not allow direct connections. The wireless adapter supports up to 802.11N.

BRAVIA™ Internet Video

Once available as an optional device to connect to the television, this feature is now an integral part of the product. The rear of the television contains an Ethernet port to connect to a high speed network. Access to online music and video through partnered websites is possible.

Personalized “widgets” are small applications that can be placed on the screen and accessed with the touch of a button to bring up programming such as weather, stocks and sports information.

Enhanced Cross Media Bar (XMB)

A new graphics user interface with rich 3-D graphics allowing the user to customize the setup of the television and to access various adjustments and control optional devices. Optional external devices can also be detected and displayed. One example would be when a USB storage device is plugged into the USB2.0 side input that contains JPEG format photos. The detection of the device will appear in the XMB graphics icons along with thumbnail views of the photos stored on the device. The photos can be viewed individually or be displayed as a slide show.
