LED Backlight Design Competition Project Matured Complicated

70% for manufacturing a rare metal , indium , indium tin oxide target (ITO), ITO for manufacturing a liquid crystal display (LCD), thus manufacturing a liquid crystal display Indium (LCD) of the important material. LCD TV panels accounted for more than half of the overall cost is a major factor affecting the cost of LCD TV 's , LCD TV panels accounted for more than half of the overall cost is a major factor affecting the cost of LCD TVs , but also smart phones, tablet PCs , automotive displays the main component. High-generation production line mainly produces 32-inch large-size LCD panel, generally defined as more than six-generation line , called high- generation line , high-generation line.

Market research firm NPDDisplaySearch noted that in 2014 the LED industry is basically going to be a good year , the main reason is that , LED backlight market demand for flat demand , but the lighting market demand continues to heat up ; together with vendors for new MOCVD careful assessment of the device, resulting in supply since 2014 after gradually reach a stable level of demand .

But NPDDisplaySearch also pointed out that because of the lighting market specifications confusion and lower barriers to entry , the entire lighting market demand becomes a small variety of forms, less favorable for large-scale enterprises , the big companies are taking a single specification in the lighting and fixed gross rate business model ; while in the case of LED backlighting applications , can be found in LED notebook (Notebook) backlighting applications has reached 100%, while the monitor (Monitor) is almost 100%.

And TV from 2011 to the beginning of the backlight LED, just three years LEDTV penetration has reached 99% , more developed the so-called direct type backlight , backlight design to the fullest , but also led to the new supply chain , for example : BMS (BacklightModuleSystem), direct type LED light source , optical lens and the second direct type backlight of playing pieces ; while some of the original because there is no backlight module manufacturers to keep up with this wave of backlight design changes have been eliminated.

It can be said when the flat panel display backlight design matured, not just purely technical and service competition each company , more than is whether the size of the company and the group's supply chain can meet ; project because the more competition for more , resulting in the flat panel display industry continues to reshuffle the backlight , the bigger the trend has become more evident .

Although the overall LED backlight market did not change much , but the economies of scale and technological capabilities erected a wall , so latecomers can not be entered , but not like a negative gross margin of lighting applications happen, and as the whole plant or the system works as TV prices increasing pressure , the integration efforts will become increasingly large , continuous compression of the small plants living space, we can see that since the direct type backlight module concept began in 2011 to replace the traditional the CCFL backlight, the thickness of the main principles of sacrifice and get a better cost advantage, but as technology advances more and more , as thin when the thickness has been only need to sacrifice some or thickness and side- backlight time, advantages and other advantages of the direct type backlight module cost ─ ─ on the ease of doing such a narrow frame , suitable for localdimming ─ ─ will gradually erode the side- 's high-end models , the main idea is they can without sacrificing thickness reduce costs.

All the advantages of making direct type backlight penetration increased from 45.9% in 2013 to 53.9% in 2014 , and annual growth of approximately 17.1% compared to 2013 ; Outlook 2017 , direct- penetration is estimated to be 61.3% . But there will be any technical bottlenecks, whether direct type backlight design to achieve a balance between performance and price , mainly depends on whether the secondary optical design to the limit ; addition to the direct type backlight design in the end how much OpticalDistance (OD) for the mainstream ? Whether wide gamut era came ? Are worth exploring themes.

NPDDisplaySearch also said demand for small- size backlight , backlight how existing thinning is the main design focus ; while the merits of the backlight module designed for handheld devices has a great impact on the use of time . Also the rise of high-resolution display , the backlight or backlight design also affect different panel backlight penetration will be different for the next variable encountered backlight design will be more complex.
