Taiwan launched the world's earlier LED backlight module LED Light Bar measurement standards

Taiwan Industry Association SEMI 16 announced that the AU Optronics, EPISTAR, Mao, ITRI measurement center of Taiwan display industry downstream industry cooperation, through the SEMI international standard industrial technology platform, integration in the United States, Japan and South Korea, Europe and other countries, have dominated by global first a liquid crystal display LED backlight module of LED Light Bar measurement standard. It is expected that it will be helpful to reduce the cost of production and communication.

AU Optronics Technology Center Deputy General Manager Lu Yonghong said, the display industry is quite large and complex network connection, technical standard of international industry is one of the key industrial development. The Taiwan industry through the SEMI platform to achieve international consensus, led by the international industrial standard LED Light technology Bar detection of global first LCD display, not only applicable to the related industries in Taiwan, can reduce the strength of foreign manufacturers leading non standard measurement method of threat, on the other hand, to prove that Taiwan International technology independent and specifications on the strength of.

With energy saving and carbon reduction into the global terminal product design focus, LED backlight module NB backlight has become mainstream since 2009, due to the gradual decline of LED backlight module prices, so the LED backlight module in TV and monitor the field permeability also increased year by year. 2011 first quarter of the global LED backlight LCD TV shipments grew to 15 million units, compared with the same period last year, only 3 million units, several times growth. LCD TV shipments in almost every region, there are more than 20% LED backlight models. Especially in the size of 40 inch LCD TV penetration reached more than 50%. Among them, the majority of the use of side light type LED backlight design.

SEMI pointed out that the LED LCD industry 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. In addition, the manufacturers use different environmental settings and geometric conditions to measure, but also cause inconsistencies in the test 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.

The liquid crystal display through the use of LED backlight module LED Light Bar measurement standard, the definition of 2D image analysis method can also calculate more brightness, and can accurately detect the defects of LED Light Bar offset playing pieces, shorten the testing time, and synchronous detection and design of optical mechanism. The formulation of the measurement standard for flat panel display industry, with the 3 large economic benefits, including: the downstream industry will have clear specifications and the same communication language, reduce disputes; testing environment and method to obtain clear definition and analysis of LED Light Bar quality more accurately; improve the quality efficiency of delivery pipe with the product.

SEMI Taiwan FPD international industry technical standards committee in July 2008 approved, officially became a SEMI FPD international industry standards committee, Taiwan flat panel display industry downstream, and government platform of research experts to exchange 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 Liu Jiaming, CO chaired, under the establishment of a sub committee and 6 working groups. Including AUO, CMO, CPT, PVI, EPISTAR graphic display and LED manufacturers, and are involved in the meeting to formulate the standard of SEMI.
