According to industry analysis, LED TV has been actively growing in the near future. The growth of EDGE LED TV with Slim Design advantage is particularly significant. In the first half of 2010, the light guide board and related raw materials of EDGE LED TV core optical components were in short supply, and the core material of the light guide plate was in short supply. One of the market prices of MMA and PMMA continues to rise, and the production of light guide plates for the production of special diffusion lines has been expanded, which has intensified competition among light guide manufacturers.
Recently, the LED TV inventory is too high, and the production scale of LED and LCD TV has slowed down compared with the first half of the year, which in turn affects the production rate of the light guide plate production line.
The industry expects that in 2011, the LED TV market will reach 78 million units, of which the demand for EDGE LED TV will continue to increase. The current relatively low light guide production line will double the market demand. The TV market has had a negative impact. In addition, the overall supply of MMA raw materials will continue to be compact in the future, which will enable light guide manufacturers to continue to invest in the development of thinner, high-intensity and new processes/new materials.
Thinning: The thinning technology of the light guide plate is regarded as a slight mitigation of the chronic shortage of raw materials for the light guide plate, and also contributes greatly to the thinning of the TV machine. But the development of thinning is not a one-off. At present, in the market mainstream specifications, the thickness of the leading manufacturers is about 3.5mm / 3mm, and the thickness of the products that officially entered the EDGE LED market in 2010 is about 4mm. At present, the thickness of about 3.xmm is widely reduced to 2.xmm level, and problems such as heat resistance and luminance loss must be solved first.
High-luminosity: The late-stage manufacturers entering this market are added to the Lenticular Pattern on the light guide plate itself, or the Prism method is achieved in the Dot Pattern formation stage, which can achieve the effect of slightly increasing the brightness. There is a trend to actively develop high-brightness light guides.
New Process/New Materials: Some manufacturers want to manufacture T-guides by shooting a streamlined process. Senior analysts in the industry believe that although the technical feasibility has not been proved so far, there are still some uncertainties, but the technology itself is innovative technology, so many manufacturers are continuing to invest in mass production technology. Development.
