          LED TV is expected to introduce a single-sided backlight design structure in 2012

          The direct-lit backlight design used RGB three-color LEDs in the early days, but the cost was too high. Later, the white-light LEDs were used as backlights for the edge-lit backlight design, which greatly reduced the number of LEDs and reduced the cost. The light guide plate guides light and makes the light distribution uniform, which is the most cost-effective.
          According to the manufacturer's data, the backlight structure of the side-lit LED-backlit TV in 2010 has been reduced from the original up and down and left to a total of 6 LED light bar designs to a total of 4 on the upper and lower sides, and its LED luminous efficiency is from the original 52 lm. /W is increased to 62 lm/W, but the amount of LED is reduced by 20% to 25%.
          It is expected that in 2011, LED manufacturers may further introduce a LED backlight bar with only one LED light bar on the left and right sides of the panel. In 2012, the TV may even import a single-sided light, which means the left side of the TV panel. On the side or on the right, use only one LED light bar backlight to design a new model.
