TUV-SUD certified for four hazardous substances analysis technique
Giheung Corporate R&D Center, 2007
The analysis team of the Center won certification for the internationally recognized analysis technique for RoHS substances to successfully respond to global environment regulations. The Team put together a task force team for three months from February 2007 and began preparation for certification to be qualified as "Internationally certified testing lab for hazardous material analysis." After going though preliminary testing and final testing in April 2007, the Center won the final confirmation for the certificate in May. Testing subjects for certification are electronics products and components. The Center secured testing methods for four regulated RoHS materials of lead, cadmium, hexavalent chromium, and mercury pursuant to ISO 17025 and IEC 62321 specifications. The certification provided Samsung SDI an opportunity to improve public confidence in environment friendly policies and technological competency as well as lead analysis technique development.

AMOLED life cycle enhancement
Giheung Corporate R&D Center, 2007
Since 2006, the Center has worked on the project of improvement of life cycle of 2" AMOLED. The goal was to build a product twice as better as existing ones in terms of power consumption and life cycle. The Center developed a new operating technology to improve power consumption and improved light emission efficiency of materials and product structure to increase the life cycle. As a result, the product became 70% brighter at 50% less power, lasting 250% longer than existing products.

Development of fuel cells with 15% of electricity efficiency
Giheung Corporate R&D Center, 2007
The Center enhanced the performance and electrical efficiency of mobile fuel cells using LPG. Compared to old internal combustion engines whose electrical efficiency was measured at 8%, the newly developed fuel cell was measured at 15%. The new fuel cells are environment friendly products as they generate only a fraction of exhaust generated by their old counterparts. This new line of products would become available in the market with more efficiency improvement later.

RoHS +
Rechargeable battery, 2006
RoHS, the environmental regulation authority in Europe, regulates the use of six toxic substances harmful to humans and the environment in electronic and electric products. Not all hazardous materials are regulated. How toxic and whether those materials can be replaced determinds which substances to regulate.

Teraboromo-Bisphnol (TBBA) and Antimony Trioxide is a substance not subject to regulation but use of an alternative material where possible is highly recommended. Samsung SDI, in conjunction with suppliers, undertook a research that led to the removal of theses materials from all materials for the BL-4C battery pack. Apart from six RoHS materials, it will continue its efforts to remove other materials hazardous to people and environment from its products.

Stronger, more, cleaner!
Rechargeable battery, 2006
The electrical power supplied to a machine when a machine is turned on is called its generating capacity. To operate a large and heavy machine which consumes a lot of energy, the battery capacity needs to be high and the output must be maintained above a certain level.

When an electric current is met with high resistance, energy consumption increases. Samsung SDI lowered the resistance that is generated when an electric current passes within a battery, enhancing the energy efficiency. Compared with existing cylinder-type Li-ion batteries, the new battery has an output 50% higher at continuous output. Its mechanical strength was also enhanced by 33%. With such improvements, Samsung SDI was able to successfully provide batteries suited to cater for expert electric tools, which require higher capacity batteries than ordinary ones.

Safety Improvements were also made for our batteries. Samsung SDI added Lithium carbonate and redesigned the battery structure so that current would be disconnected in the case of excessive current or voltage. This is to prevent the occurrence of overheating or explosion.

Convenient and clean energy
Fuel cell, 2006
Crude oil prices are going up and concerns over global warming and the green house effect are growing. Fuel cells are like a small power generator, which can generate power continuously as long as fuel supply is consistent. They do not rely on fossil fuel and do not emit any pollutants. Only water is expelled after energy generation after a series of chemical reactions. The fuel cell will generate infinite quantities of energy as long as its fuel cartridges are replaced now and then.

Samsung SDI’s aims to develop a method for building smaller fuel cells which can generate more energy with less fuel. In 2006, Samsung SDI developed a fuel cell that was 23% more energy-efficient than existing 20W note PC. The new cell was 30% smaller and produced 21% more energy per cubic volume. The noise level during operation of the fuel cells were also reduced to 37dB.This is very unlikely to cause disturbances within our daily lives, as a quiet conversation we may enjoy in a library measures at 40dB.

One charge goes a month; a cup full lasts15 hours
Fuel cell, 2006
One charge enables you to use your laptop for a month. Samsung SDI, in conjunction with Samsung Electronics and Samsung Advanced Institute of Technology, developed a 1,200Wh grade large capacity fuel cell.

The fuel cell can support usage of a 12" mobile laptop with an average capacity of 12~15W, eight hours a day and five days a week before the fuel cartridge requires replacement. This is the world’s current longest possible usage between charges and 1.6 times longer than that of the fuel cell Samsung SDI presented late last year. The maximum capacity can now reach up to 20W and the energy density, the amount of energy from a cubic volume, is measured at 650WH/L which is four times higher than its rival products. Samsung SDI also succeeded in developing a compact fuel cell which allows 15 hours of usage of a notebook PC with less than 100cc of fuel.

Halogen Free
LCD, 2006
In 2004 Samsung SDI completely removed materials categorized as harmful by the RoHS from their LCD modules. In 2005 it successfully developed a range of PVC free products and continued their success with the release of halogenated flame retardant-free products in 2006. To enable the removal of halogenated flame retardants from its LCD modules, the company analyzed the constituent substances in 11 LCD models and 184 of its components. We then exchanged 24 Halogen containing components of the 184 components with Halogen free

Samsung SDI is compliant with customer requirements for environmentally-friendly products. We stand ready to respond to a customers’ call at any time.

Chameleon
LCD, 2006
There is a LCD whose color and brightness change depending on where it is used. The 2.3" QVGA TFT-LCD, a newly developed product, senses light within a certain environment and adjusts itself to the optimal screen brightness at a particular abundance of light.

The light-sensor within the product measures light intensity within an environment. The Automatic Brightness Control (ABC) function is controlled by the Mobile Image Enhancement (MIE) program to control brightness and colors of images on display depending on the detected brightness.

Indeed the screen brightness becomes reduced in a dim place, while displaying brighter images in a bright place, providing optimized images to a place where it is used. As it alters its brightness automatically, it can reduce power consumption by 30-50% on average, compared to conventional TFT-LCDs.

It stands as the key next-generation technology to be integrated into mobile display products such as mobile phones, DMB, PMP, and UMPC. It can provide clear pictures outdoors and prevents glare, delivering far batter picture quality than conventional products.

29.9cm, UltraVixlim!
CRT, 2006
When buying TV, consumers study three things; price, quality and design. Existing CRT offer good picture quality and a reasonable price, but are thick and heavy. If they could be slimmer, they could satisfy all of the three consumer requirements in terms of price, quality and design.

Samsung SDI made the CRT slimmer for the sake of a more attractive design. Samsung SDI unveiled the 35.2 cm thick Vixlim in 2005 and 29.9 cm thick Ultra Vixlim in 2006, which was 31% slimmer than the conventional CRT. In addition, new CRT were applied with a large flat panel TV-like exterior, complementing home interior. Consumers purchasing FDP showed preference to the table-top stand style as opposed to the wall-mount style. The table-top stand type requires extra fixture. Comparing the spacial requirement of a table-top stand LCD TV and Vixlim, there are no notable differences in terms of space consumption and exterior look. This is a case of Technology enhancing the design-oriented competitiveness of a product.

In addition, Vixlim has avoided image distortion at the edges of the screen. Samsung SDI endeavors to improve both quality and design of its products.

With these achievements, Vixlim is regarded as the product that brought the second golden age to CRT displays. By 2006, sales figure of Vixlim had reached 6 million units after just two years since its release.
