In the TFTLCD industry, LED backlights have evolved into an important key component and will continue to grow in the coming years. According to DisplaySearch's latest quarter LED backlight research and analysis report, it is estimated that in the fourth quarter of 2012, the shipment of LED backlight panels for large-size LCD panels will exceed the shipment of cold cathode fluorescent lamps (CCFL) backlight panels, and penetration. The rate will be as high as 80%.
DisplaySearch pointed out that LED is undoubtedly the mainstream light source in the future LCD panel, mainly because of its unique ultra-thin design, low power consumption and high image quality, which is rare for display material suppliers. Good opportunity. For example, PMMA (commonly known as acrylic) is used in light guides, white polyester (PET) is used for reflective films, and sapphire for LED epitaxial substrates.
Large-size LED backlight panel shipments surpass CCFL in 2012
However, liquid crystal manufacturers have faced the dilemma of shortage of key components of LED backlights since the first quarter of 2010. The production of TV light guides is also limited by the shortage of PMMA. And the needs of many reflective film suppliers are also moving between LCD panels and solar cell applications. In addition, many LED manufacturers are also facing a shortage of sapphire substrates (especially 2-inch substrates).
Kevin Kwak, director of research on DisplaySearchLED backlighting, pointed out: "Many LCD panel manufacturers do not want to recognize the capacity of major material suppliers before they correct their LED TV panel shipment targets. In particular, the shortage of PMMA and PET is quite serious, PMMA and PET. Suppliers need time and increase their equipment under limited funding, resulting in a very slow expansion of capacity."
How can we solve the out-of-stock situation of some of the roles in the supply chain? DisplaySearch believes that with LEDs, more LED manufacturers can be recognized, improve the design of LED backlights and reduce the number of chips, the phenomenon of out of stock Will help. In addition, co-investment LCD manufacturers and PMMA suppliers can also ensure the supply of light guide materials.
Kwak added: "In order to successfully expand the market for LED-backlit LCD TVs, LCD TV panels or TV manufacturers must consider product competitiveness, including successful procurement strategies, innovative designs, organized business models and sales strategies, as currently LED backlight LCD TVs are still expensive for many consumers."
A manual pulse generator (MPG) is a device normally associated with computer numerically controlled machinery or other devices involved in positioning. It usually consists of a rotating knob that generates electrical pulses that are sent to an equipment controller. The controller will then move the piece of equipment a predetermined distance for each pulse.
