Gaogong LED Network News (Reporter Hu Yanling) Accumulation Technology takes "providing quality leading, high-quality driver IC" as its mission, successfully occupying 55% of the global display market share, and took the top spot of LED Display Drive. The leading position of LED display, meanwhile, the global ranking of LED driver IC suppliers from the ninth in 2006 leap to the third place in 2010.
Kara offers a wide range of illuminated and non-illuminated Rocker Switches.Ranging from 4 to 9poles,16VA to 30 amp,with many styles of colors and functions,especially the switches with High-Current and some types which meet the industry standard IP65,IP68. Certifications include UL, CSA, TUV, CE, and more.

“Gathering Technology provides leading design concepts for driving ICs and strives to make certain contributions to the LED industry.†Wu Zhongyou, deputy general manager of Accumulation Technology, said that the company has proposed that the display driver ICs should meet the “three high-performance†and “three lows†last year. "The appeal" has been accepted by everyone.
Energy conservation is a topic that cannot be avoided in the LED industry. How to effectively save energy is the proposition of the whole industry thinking. Driver ICs began to show energy-saving demands, and Accumulation Technology decisively pointed out that energy conservation is the future trend of driving ICs.
Accumulation Technology has a leading edge in the display field. At the same time, the company began to develop the lighting market and strive to continue the glory of the display market. 
"Innovation" and "Service"
Accumulation Technology firmly believes that the source of profit from enterprise operation is “innovation†and “serviceâ€. Accumulation Technology is committed to innovation in circuit design, paying more attention to management innovation and product marketing innovation. In addition, Accumulation Technology attaches great importance to customer needs and provides customers with unique and unique A solution to economic efficiency.
With strong R&D capabilities, in 2010, Accumulation Technology launched 15 new products including display and lighting driver ICs. In 2011, it is expected to launch 13 new products. According to Wu Zhongyou, the company's product development related departments are about 150 people, providing strong technical support for the development and update of new products.
“The technology of accumulation is relatively solid, and the core technology allows customers to have no worries. The lifeblood of a company lies in the products, and the products that support the products are technologies. With successful products, successful marketing and consultants are needed.†Wu Zhongyou said that in terms of product sales The lighting driver IC market will abandon the past model of IC-type shipments in the display market, and will be shipped in a modular manner to solve the problem that customers cannot handle power management AC/DC and EMI certification.
Regardless of product innovation and marketing innovation, it reflects the "customer-centric" service concept. Wu Zhongyou introduced the company's systematic service concept, that is, fully communicate with customers before designing products, thinking and conceiving products. Taking into account the needs of customers, this greatly increases production efficiency. “The previous practice was to wait for the customer to tell us, we will do it again. Now we understand the customer's needs from the beginning, and the customer's product molding will be done.â€
"If you don't cooperate with customers, you won't know where the customer's pain points." Wu Zhongyou said, "I don't understand the needs of customers, I will only recommend products to him. Every day, I ask why he doesn't use them. Customers may say The product is not suitable. Systematization is to look back from the customer's position to see what the driver chip will look like. It used to be the case, but we didn't push the process to the extreme."
Benefiting from the unremitting efforts of “innovation†and “serviceâ€, in 2010, Accumulation Technology generated a revenue of NT$1.8 billion, and the global ranking jumped from the 9th to the 3rd, and became the world’s number one market share. LED Display Driver.
Vigorously develop energy-saving products
In 2010, the accumulation proposed that the new era of display screens should meet the "three high-performance", "three high" means "high utilization rate (greater than 90%)", "high refresh rate (greater than 1000Hz)", "high gray scale (more than 14bits)". In 2011, Accumulation Technology put forward “three low demandsâ€, “three lows†means “low energy consumptionâ€, “low residual image†and “low EMIâ€.
"Reviewing what happened in the past year, we have indeed implemented the policy of three highs and three lows, but we have not completely finished it. At present, the products have reached the stage of low energy consumption. We propose that energy conservation is the development direction of driving ICs in the future." Wu Zhongyou Introduction, in the field of display, Accumulation Technology uses low-break voltage technology to achieve energy-saving purposes; in the field of lighting, the use of improved conversion efficiency to achieve energy-saving purposes.
Driving the constant current IC requires sufficient voltage, that is, the threshold voltage, to achieve the effect of constant current. The sum of the threshold voltage and the minimum voltage required for the minimum constant current of the LED is the cost necessary for the system to achieve the expected work. Under the premise that the current is constant, to obtain the required brightness, only by lowering this voltage can the low power consumption be obtained, and the voltage becomes lower with the turning point voltage. When the supply voltage becomes lower, it saves energy.
Accumulated in 2011 to introduce the low turning voltage product MBI5035, this product can not only reduce the power consumption of the display, but also reduce the generation of waste heat. Laboratory data shows that the 3.8V single-voltage design saves 24% compared to the 5V system, and the IC heat loss is reduced by 60%; the 2.8V/3.8V voltage design saves 31% compared to the 5V system, and the IC heat loss is reduced by 77%.
"In the field of lighting, we can't talk about voltage separately. We provide high conversion efficiency." Wu Zhongyou pointed out that DC-to-DC converters, or AC-to-DC converters, represent conversion efficiency. Conversion efficiency can generally be around 90%, and sometimes it will be reduced to 85% in consideration of heat dissipation and other factors. "Our company's products have reached a certain level of technology, high can achieve 92%, plus other considerations, at least 85%."
“ Energy saving is the future development trend,†Wu Zhongyou said. “Energy saving can enhance the product and company image and enhance the added value of the product. At the same time, energy saving means saving money.†
