Traditional Light Tower
A traditional light tower is a tall structure that is equipped with powerful lights to provide illumination in various settings. It is commonly used in construction sites, outdoor events, emergency situations, and other areas where temporary lighting is required.

Traditional light towers typically consist of a sturdy metal frame with a mast that can be extended to different heights, allowing the lights to be positioned at various angles and distances. The lights themselves are typically high-intensity discharge (HID) lamps or light-emitting diodes (LEDs), which can produce a bright and focused beam of light.
These light towers are often portable and easy to transport, allowing them to be quickly set up and moved to different locations as needed. They are usually powered by diesel generators or other sources of electricity, ensuring that they can operate independently of the local power grid.
In addition to providing illumination, traditional light towers may also be equipped with other features such as telescopic cameras for surveillance, outlets for powering tools and equipment, and even solar panels for eco-friendly operation.
Overall, traditional light towers are essential tools in various industries and applications, providing reliable and efficient lighting solutions in areas where conventional lighting may be insufficient or unavailable.
BOE's 10.5-Year Mass Production Drives Large-Scale LCD TV Market Size
In a recent report by Korean media outlet ET News, it was revealed that Samsung Display and LGD are planning to increase the use of MMG (Multi-Module Glass) technology in order to boost their presence in the 70-inch LCD TV market. This strategy aims to improve production efficiency, especially as the industry moves toward larger screen sizes.
BOE’s 10.5-generation line is expected to start mass production in Q1 2018, offering high cutting efficiency for 65-inch and 75-inch panels. Currently, the highest generation line used by most panel manufacturers is the 8.5-generation line. However, to stay competitive, companies must enhance production efficiency and adapt to new technologies like MMG.
Under normal circumstances, a single mother glass substrate can only produce one size of panel. For example, an 8.5-generation line can cut 18 pieces of 32-inch panels, 8 pieces of 49-inch, or 6 pieces of 55-inch, with a cutting efficiency above 90%. However, when producing 65-inch and 75-inch panels on an 8.5-generation line, the efficiency drops below 70%. To address this, manufacturers have adopted the MMG approach, where different panel sizes are cut from the same glass, such as two 65-inch panels plus six 32-inch ones, or two 75-inch panels plus two 49-inch ones.
Although MMG improves cutting efficiency, it comes at a cost. The yield rate tends to decrease due to the complexity of producing multiple panel sizes from a single glass. Additionally, the production cycle may be extended, leading to lower output per unit time. Industry experts estimate that MMG could reduce yield by 5% to 6%, with some cases seeing up to a 10% or even 20% drop depending on the manufacturer's technical capabilities.
LGD was the first panel maker to implement MMG globally, and they have since refined the process with strong technical expertise. In Guangzhou, LGD is now fully adopting MMG for its 8.5-generation line, with 65-inch and 32-inch combinations already in production. This year, the company also launched 75-inch and 49-inch MMG production. Currently, more than half of the Guangzhou plant’s output uses MMG.
Samsung has also embraced MMG, using it in its Suzhou 8.5-generation line and the Yujing L8-1 line. They have been shipping 65-inch and 32-inch MMG panels while continuing to increase production of single-cut 75-inch panels. At present, over half of the Suzhou Plant’s capacity uses MMG, and discussions about increasing MMG usage in other lines are ongoing.
This year, both Samsung Display and LGD have seen record-high output for 65-inch and 75-inch panels. LGD’s 75-inch output stands at 30K/M, while Samsung Display produces 50K/M. As demand for large TVs continues to grow, the proportion of MMG in production is expected to rise further.
The launch of BOE’s 10.5-generation line in 2018 is set to accelerate the growth of oversized TVs. According to CINNO Research, shipments of 60-inch and larger TV panels will reach 22 million in 2018, surpassing 40 million by 2022. 65-inch and 75-inch models are expected to dominate the market.
While BOE and CSOT mainly apply MMG to smaller panels (up to 43 inches), AUO is exploring MMG for 65-inch and 55-inch panels, aiming to cut three 65-inch units and two 55-inch units from a single glass.
Industry sources note that as LCD TV prices decline, the drop is more significant for screens below 50 inches, while larger sizes remain relatively stable. With a saturated TV market, manufacturers are pushing for oversized and high-end products to find new growth opportunities. This trend suggests that the 65-inch and 70-inch markets will see substantial growth next year.
