Taiwan plant launched the world's first display LED Light Bar measurement standards

SEMI recently announced that in Qili AUO, EPISTAR, Zhi Mao, ITRI measurement center of Taiwan display industry and downstream industry cooperation, through the SEMI international standard industrial technology platform, integration in the United States, Japan and South Korea, Europe and other countries, led by LED Light Bar global first a liquid crystal display LED backlight module within the measurement standard, will help the relevant industry production and reduce the cost of communication.

Cao Shiguan, President of SEMI Taiwan and Southeast Asia, said that the international industrial technology standards is the key to the development of industrial technology and reduce manufacturing costs.

AU Optronics Technology Center Deputy General Manager Lu Yonghong said, the display industry is the link network structure is quite large and complex, technical standard of international industry is one of the key industrial development. This through the SEMI platform to achieve international consensus, led by international industry technical standards LED Light Bar detection of global first LCD display, not only is more suitable for Taiwan related industries, but also can reduce the strength of foreign manufacturers leading non standard measurement method of threat, on the other hand, again to prove strong strength in Taiwan technical specifications on international and independent.

Carbon has become the key design of terminal products under the global reduction in energy saving, LED backlight module NB backlight has become mainstream since 2009, with the decline in prices in the LED backlight module, TV and monitor the field permeability also increased year by year. LED LCD TV shipments in the first quarter of 2011 increased from a year ago to Taiwan, up to 1 billion 500 million units.

The LED TV because of the rapid decline in emerging market prices and popular, almost every region in the LCD TV shipments of more than 20% of the LED backlight, mostly side light LED. In addition, LED in 40 inches above the size of LCD TV penetration reached more than 50%.

LED LCD industry in the upstream and downstream manufacturers, including LED chips, backlight modules, panels, etc., quality and manufacturing costs. The traditional method of detection of LED Light Bar only single brightness measurement or sampling area can only achieve single brightness, brightness value, and when the number of LED increased when the detection work becomes very time-consuming, on the other hand, the manufacturers use different settings and geometric conditions to measure, also caused the inconsistency detection data.

Therefore, the past relevant industry did not detect LED Light Bar comprehensive, often to the problems found after the assembly of the backlight module, not only trace the problem is rather difficult, and will increase the cost of production, the delay shipment schedule.

ITRI Measurement Center Deputy Director Lin Zengyao pointed out that the standard LED Light Bar measurement method and communication language for testing equipment manufacturers, do not need to be tailored to individual customer requirements of the measurement method to adjust the machine, can greatly reduce the cost of manufacturing and research and development.

Standard for LED backlight module LED Light Bar measuring the liquid crystal display through the definition, 2D image analysis method can also calculate more brightness, and can accurately detect the defects of LED Light Bar offset playing pieces, can greatly shorten the testing time, and synchronous detection and optical mechanism design. The formulation of the measurement standard of flat panel display industry has 3 major economic benefits, including upstream and downstream industry have clear specifications and the same communication language, reduce disputes, through the standard definition of test environment and analysis method, LED Light Bar quality is more accurate, and effectively improve the quality and efficiency of product delivery quality.

SEMI Taiwan FPD international industry technical standards committee approved in July 2008, officially became a SEMI FPD international industry standards committee, Taiwan flat panel display industry downstream, and government research experts an important platform for exchange of views.

The current measured by the Industrial Technology Research Institute deputy director of the center for Lin Zengyao and TDMDA Taiwan flat panel display materials and Components Industry Association executive director Liu Derek, CO chaired, under the establishment of a sub committee and six working groups. Including AUO, CMO (3481-TW), CPT (2475-TW), PVI (8069-TW), activities and meetings for crystal electric plane display and LED manufacturers are actively involved in the SEMI standard, with the full cooperation of upstream and downstream industry to share and domestic standards of professional and technical consensus.
