According to DIGITIMES Research, TFT LCDs, which currently occupy the mainstream of display technologies, must be matched with backlight modules because they cannot emit light. In light of the fact that energy-saving and carbon-reduction has become a global terminal product design, LED backlight modules have become thinner and lighter than traditional cold cathode tube (CCFL) modules, have a long life, do not contain heavy metals, and save power. They have become a backlight for NB since 2009. The mainstream of the source, with the price of LED backlight module decreased, the penetration rate in the field of TV and monitor has also increased year by year.
In addition to the decline in LED prices due to global capacity expansion and yield increase, the reasons for the cost reduction of the overall LED backlight module are analyzed, including reducing the number of backlight strip configurations, reducing the number of LEDs mounted, and reducing the number of components needed for the LED driver circuit.
In order to reduce the amount of LED driver ICs for the unit panel, the LED driver IC technology can drive the development of multiple LEDs. At present, only one LED driver IC, LED monitor and TV panel average LED driver IC are required for each LED NB backlight module. The usage also declined from 3, 8 in 2008 to 1 to 2 and 4 in 2010.
Although the number of units mounted on the panel has declined, the penetration rate of LED backlights for panels used by IT (NB, monitors) and TVs has increased. The demand for LED driver ICs for large-size backlights used by Taiwan's panel makers is estimated to be 1 from 2008. With 4.52 million units, the number of LED driver ICs for TV backlighting reached 270 million, and the number of LED driver ICs used in TV backlighting reached 140 million, which is the key to the layout of related IC designers.
Among them, the Taiwanese IC design industry, after product technology has been gradually put in place, with better supply chain flexibility and lower prices, Taiwan's panel factory shipments growth is stronger than the international IC manufacturers, estimated in 2011 will reach 130 million, In 2010, 57.4 million units saw a significant growth of 128.4%, which was better than the 52.2% growth rate of international chip suppliers in the same period.
