Sony to Release 65-, 55-inch 4k TVs
Sony Corp announced April 11, 2013, that it will release 4k (3,840 x 2,160-pixel) LCD TVs June 1, 2013.
This time, Sony announced the 65-inch "KD-65X9200A" and 55-inch "KD-55X9200." It released a 84-inch 4k LCD TV in September 2012. And the new TVs are the second series of the company's 4k TVs.
For the new TVs, Sony employed the Triluminos Display, which expands color space, and magnetic fluid speakers. The Triluminos Display uses the "Color IQ," QD Vision Inc's light-emitting semiconductor technology using quantum dots. When white LED backlight is applied to an optical component using the Color IQ, the light is converted into a white light including high-purity blue, green and red colors, expanding color space.
The magnetic fluid speakers realize a suspension function without a damper by using magnetic fluid. When a damper is used for a speaker, it generates a secondary sound pressure, causing sound distortion.
The magnetic fluid eliminates the need for the damper, solving the problem of secondary sound pressure. Also, it enables to shorten the transmission path from the voice coil to the diaphragm, reducing transmission loss and clarifying sound, Sony said.
This time, Sony also improved the function to connect the TV and mobile devices such as smartphones and tablet computers. Specifically, the company realized the following three functions by using the NFC (near field communication) function of a mobile device.
First, the "One-touch Mirroring" function shows the screen of a mobile device on a TV's display when the user touches the remote of the TV with the mobile device. Second, with an application software called TV SideView, it is possible to use a mobile device to check TV programs and change settings for recording them. Third, video files stored on a mobile device can be transmitted to a TV with a new function based on MHL.
The One-touch Mirroring was realized by a connection handover from NFC to wireless LAN. And, for video transmission, the Miracast method of the Wi-Fi Alliance is used. However, this function can be used only with Sony Mobile Communications Inc's latest smartphones and tablet computers released in 2013.
There are no manufacturer's suggested retail prices. But the expected retail prices of the 65- and 55-inch TVs are ¥750,000 (approx US$7,657) and 500,000, respectively.
