Redefining the concept of television, Japanese electronics giant Panasonic has announced a new TV that turns ‘invisible’ when switched off. When the TV is switched off, the screen looks like a transparent pane of glass and the users can clearly see through it.
Panasonic has made many improvements on the prototype TV which was introduced first at Consumer Electronics Show (CES) in January in Las Vegas. The company is still working on the TV to make it completely transparent and will be available for end users in a few years.
Panasonic has replaced the LED screen for a new OLED (organic light-emitting diode) display that does not require a backlight, unlike LCD, to illuminate pixels. The earlier models required a backlight to illuminate the screen to make the picture brighter. But, the OLED model does not need background lighting.
Light is produced when electricity is applied through OLED which is thinner than LCD and easy to make. An OLED panel is made up of a layer of plastic inserted between two electrodes.
Panasonic replaced the LCD display with OLED as the company was not happy with the transparency of the previous display, reported tech website Engadget.
“The OLED screen is made from a fine mesh, embedded into the glass sliding door,” explained Engadget.
“While the TV image is visible even with the backlighting on, once it’s dimmed the image is clear and bright enough to be almost indistinguishable from existing televisions,” it added.
As OLED is made up of transparent elements, it remains transparent while it is not working and produces light when electricity is applied.
Recently, LG had unveiled a TV screen that can be rolled up like a newspaper.
