Organic Light Emitting Diode TV

Sony introduced the world's first OLED TV back in 2007, the XEL-1
A 4K OLED TV has 8.3 million pixels. Each pixel is a tiny light bulb
Turn them off and you get absolute black. Turn them all on and you get white, or any mixture thereof. its like having 8.3 million zones.
Most consider the OLED to produce the best picture.
But, tose tiny light bulbs don't put out as much light as a regular LED TV and they are more expensive.
In a bedroom where there's not tons of light they produce outstanding, high contrast, beautiful color picture.
Sony whose name comes from the Latin for sound invented a new way to produce sound from a TV ... vibrate the screen. Only Sony OLED TVs use the screen as speaker and Sony OLED TVs have the best built-in sound of any flat panel TV
So, the Sony XBR-A9S OLED TV with Ultimate X-1 Processor has a great picture, great sound, and a great price
The X-1 Processor improves the picture object by object
