Here comes an impressive technology for the eco conscious! Get set to go green with eco friendly televisions, an area of technology that is ready to explode in innovation. Green living ideas have made their way to our living rooms and eco TVs have evolved in to something more significant than being just an aspect of entertainment.
Many manufacturers have come out with eco-aware televisions that would take a bite off your electricity bills. For the eco friendly masses who would rather scrimp on plastic bags but not on the picture quality, Philips has a solution. The energy star rated Eco TV 42PFL5603D from Phillips is stacked with energy efficient features. Chief among these is the auto-dimmer option that dims the backlight during darker scenes. The feature helps dip the power consumption and improves black level performance at the same time. The power is also adjusted according to the brightness in the room, resulting in less bright images in darker rooms. With the company’s claim of a low standby power of 0.15 watts, the Eco TV easily tops charts. It is also worth noting that the materials used for the TV are lead-free.
Sony joins the green march with its Bravia WE5 HDTV. The WE5’s 40-inch/46-inch monitor is designed to save power. The micro tubular HCFL backlight cuts the active power consumption down by almost fifty percent. The Smart Presence Sensor switches the TV off when it is left unwatched. The Light Sensor and the Energy Saving Switch are interesting additions to this pack of Sony’s eco innovation.
So, how do the televisions go green? The HCFL Technolgy is what that forms the basis of the eco-televisions ‘green’ credentials. Display manufacturers in an effort to cut down the power consumption, which is a critical factor for an eco-friendly device, integrate micro-tubular HCFL’s into the LCD HD televisions. The Hot Cathode Fluorescent Lamp (abbreviated HCFL) produces ultraviolet light when its contained low-pressure mercury vapor is energized. This UV light is made to encounter a layer of phosphor within, resulting in the emission of visible light. The visible light in turn illuminates the LCD panel. HCFL’s are widely employed in the go green technologies and they are proven to be more energy efficient than CCFLs (Cold Cathode Fluorescent Lamp). The hot cathode lamps are just as thick as a pencil and their energy consumption when compared to CCFLs are minified by 40%.
The next energy saving function that is incorporated in any eco-friendly television is the Presence Sensor that uses infrared rays. The sensor scans and detects movement and body heat in the room both in the horizontal and vertical directions. It then automatically switches the television to an energy saving mode and gradually to a standby mode after a specific delay if no movement is sensed even then. This helps save energy and the power consumption levels drop.
Another important parameter for an eco TV is the degree of toxicity in chemicals used in its manufacture. Philips claim that the level of mercury content in its eco televisions, is nothing more than a trace and the use of other hazardous chemicals like cadmium and lead have also been significantly reduced or rather eliminated.
Televisions are researched to be the thirstiest devices that drink more power compared to other home appliances. With an eco friendly television on board, relax and enjoy your favorite show in high definition with surround sound, leaving your worries on carbon footprints at bay.
