2.2 Inches Nexus5 LG LCD Screen

The discussion on the prospects of LED backlights has become a cliché. Due to the outstanding advantages of long life, low energy consumption, small size, fast response, earthquake resistance, low temperature resistance, and low pollution, its application fields are extremely broad Lcd Display. According to preliminary calculations, in the future, the electricity saved by LED lighting in China will be equivalent to the annual power generation of the Three Gorges Power Station, and at the same time it can reduce 80 million tons of CO2, 650,000 tons of SO2 and 320,000 tons of NO2 emissions, which is called "the history of human lighting. "Revolution" is not an exaggeration Active Matrix LCD.

According to G3 Comprehensive Report: From the perspective of IT, LED backlights are an important year for development in 2010. LED backlights rely on mercury-free green environmental protection, regional dynamic control backlights, low carbon energy saving, ultra-thin streamline appearance, high The advantages of color reproduction and vivid display have greatly promoted the replacement of CCFL by LED. Various large backlight manufacturers have reached a cooperative relationship with LED backlight manufacturers to jointly propose solutions and combine the latest technology of large-size light guide plates. Ultra-thin, energy-saving, environmentally friendly, and high-quality LED backlights are bound to become the next strong trend in the development of backlights LCD Display Module.

  However, the LED backlight module is not without its shortcomings. The problem of power consumption is still an important issue that the LED backlight module must overcome. Due to the use of more LEDs, in addition to the increase in power consumption, it also causes the problem of temperature rise. Therefore, cooling systems and sensors must also be added to solve this problem LCD TFT. Therefore, the thickness is thicker than that of products with CCFL backlight. .

  The development of semiconductor lighting is very rapid. Statistics show that since its inception in the 1960s, the cost of LEDs has dropped tenfold and the luminous efficiency has increased tenfold every ten years Lcd Module. And technological progress always exceeds market expectations. Especially in 2008, the Beijing Olympic Games gave LED another shot. The "dream scroll" at the opening ceremony was displayed on more than 4,500 square meters, which can be called the world's largest single full-color LED backlight. The enthusiasm of Chinese people for LEDs reached a new high when the "five-ring fantasy" formed by the arrangement of LEDs took off.
