你看不懂中文？ philips 生产CCFL， 但是不生产做为液晶面板背光的CCFL。
要不随便一个CCFL大灯管 就说是液晶面板被关CCFL。
吹牛不上税 也不用这样不顾事实， 信口开河呀！！！！

Philips Semiconductors' new 600V CCFL backlight driver offers high level functions at low cost
Eindhoven, June 19 2001 - Philips Semiconductors, a division of Royal Philips Electronics, (NYSE:PHG, AEX:PHI), has launched a highly efficient new 600V fully integrated half-bridge driver IC for liquid crystal display (LCD) backlighting. Manufactured in the company's advanced 650V BCD power-logic process, the UBA2070 can be connected directly to rectified AC line supplies without the need for a separate up/down convertor.
Philips Semiconductors has a world-class reputation for driving fluorescent lamps, such as TL and CFL types, and the high voltage technology and expertise developed for these lamp systems have now been used to extend the company's product range to include cold cathode fluorescent lamps (CCFL).
The UBA2070 high voltage, monolithic CCFL driver IC has a typical input voltage range of 12V to 600V DC. This high-voltage input capability provides an optimum system solution for CCFLs in a wide range of products that use LCD screens. These include laptop PCs, personal digital assistants and satellite navigation systems. Used with a high voltage input, the UBA2070 runs at efficiency levels in excess of 90 per cent and is ideally suited for high-power multiple-lamp systems such as those used in LCD monitors.
"The unique blend of features, coupled with the low number of external components required, makes the UBA2070 the most efficient solution currently available on the market today," said Latif Gau, product marketing manager for lighting ICs at Philips Semiconductors.
The UBA2070 offers an unrivalled range of features, including adaptive non-overlap time control, integrated high voltage level-shifting functions, a power-down function and capacitive mode protection. Also including lamp failure detection, short circuit detection and a dimming feature, it provides the highest level of integration available for fluorescent lamp driving. In particular, by dimming down the maximum light output by 95 per cent, the UBA2070 offers LCD monitor designers greater scope for enhancing the user interface.
The UBA2070 also offers system designers more freedom with respect to supply voltage choice, thus enabling a more flexible system architecture in combination with the power supply. Its outputs drive two discrete external power MOSFETS in a half bridge configuration.
Two versions of the chip are available - the UBA2070T (SO16), which is housed in a small outline package with 16 leads, and the UBA2070P (DIP16) which is a dual-in-line package, also with 16 leads.
Philips Semiconductors, which had annual revenues of approximately US$ 6.3 billion in 2000, designs and manufactures semiconductors and silicon systems platforms. Philips Semiconductors is spearheading the emerging field of systems on silicon solutions with the innovativeNexperia™ platform and VLSI Velocity™ tool set. The company's Sea-of-IP™ design methodology allows plug and play intellectual property blocks for easily customizable products. The company is a leader in communications, consumer, PC peripherals and automotive semiconductors, which are key applications for convergence in end-user products. Philips Semiconductors is headquartered in Eindhoven, The Netherlands, and has operations throughout the world.
