罗姆推出自动调光的白光LED驱动IC产品« oursolo.net

作者:企业资讯策划团队 来源:rwfb 发布时间:2010-04-13 浏览:90

日本半导体制造商罗姆今天宣布,新的LED驱动IC产品“BD6095GUL”,是在手机,PDA,个人卫星导航系统,便携式游戏机,数字多媒体播放器,外部面板的背光光源发射的目的,等设计的应用程序。

ROHM的自动调光机制BD6095GUL,能够驱动白光LED背光源,在下的低功耗长的时间显示屏能够控制背光系统,定于2007年10月可以开始出货样品,样本500日元的价格,而产品的大规模生产过程时,定于2008年2月开始,每月的产量约50万。

罗姆透露,BD6095GUL前段的ROHM的是位于日本静冈县的滨松罗姆公司生产的,然后在日本段过程中,福冈县,九州,福冈罗姆公司罗姆。

作为一个便携设备,包括互联网应用,智能应用,卫星导航和移动电视,如更多地使用环境,目前的消费液晶模块,应用效果要大得多,需要更多的能量得到背光模组,并盯着屏幕上的长期,背光模组,自动调光可以根据不同的情况进行全面良邓或运行所需的屏幕变暗。

在BD6095GUL段256优良的设计与照明设计罗姆传感器IC,可以做很好的自动调光功能。 BD6095GUL可以利用白光LED背光模块的功耗,使用的过去,三分之二的产品,获得了一个用电量减少三分之一。

BD6095GUL自动调光的照度检测元件,以及外部PWM控制元件的功能,光线和阴影的背光调整有很大的帮助。虽然PWM的行动,以减少起飞和着陆产品电压的变化。

BD6095GUL主要特点:

1,内置自动调光功能,与后续的LCD背光模块可周围的亮度,自动调节亮度传感器。
2,外部PWM机制与视频显示案件,也可以调整背光亮度。
3,内置的高效率,加强电路x1.33。
4,可与亮度传感器ICBH1600FVC。
5,脉宽调制行动,升压电路,以实现最小的变化可以防止外部简明产生报警声音。
6,自动调光,背光目前阶段调整作为256个波段的基础上调整为0.1毫安(毫安)8位。

ROHM launch automatically dimming white LED driver IC Products

Japanese semiconductor manufacturers ROHM, today announced the launch of the new LED driver IC Products “BD6095GUL”, are aimed at mobile phone, PDA, personal satellite navigation systems, portable video game consoles, digital multimedia player, external light source of the backlight panel, etc. designed applications.

ROHM’s BD6095GUL with automatic dimming mechanisms, be able to drive with white LED backlight source, the display screen in a long time under the low power consumption to be able to control the backlight system, scheduled for October 2007 can begin sample shipment, sample price of ¥ 500, while the products when mass production process, scheduled to start in February 2008, monthly production of about 500,000.

ROHM disclosed, BD6095GUL FEOL of ROHM’s is located in Shizuoka, Japan’s ROHM Hamamatsu company produces, and then process in paragraph ROHM in Japan, Fukuoka Prefecture, Kyushu, Fukuoka ROHM companies.

as a result of application of portable devices, including Internet applications, intelligent applications, satellite navigation and mobile TV, such as increased use of the environment, liquid crystal module of the current consumption is much larger, required more energy got backlight module, and a long period of staring the screen, backlight modules required for automatic dimming can, under different circumstances to carry out full-liang Teng or the operation of the screen dimmed.

ROHM designed in BD6095GUL paragraph 256 of the fine design, with illumination sensor IC, can do a good job of auto-dimming function. BD6095GUL can make use of white LED backlight module power consumption are the past, two thirds of products, access to up to one third reduction in power consumption.

BD6095GUL automatic dimming function with the illuminance sensing components, as well as external PWM control components, the adjustment of light and shade for the backlight has a great help. While the PWM action, which can reduce the take-off and landing Products voltage changes.

BD6095GUL main characteristics:

1, built-in auto-dimming function, brightness sensor with a follow-up to the LCD backlight module can be around for brightness, automatic adjustment.
2, with external PWM mechanism to work with video display cases, also to be able to adjust backlight brightness.
3, built-in high-efficiency step-up circuit x1.33.
4, can be used with brightness sensor ICBH1600FVC.
5, PWM action, the boost circuit to achieve the smallest changes can prevent the external condensed generate alarms sound.
6, auto-dimming, the backlight current stage 8bit adjusted to 0.1 milliamperes (mA) as the basis for the adjustment of 256 bands. (07-11-21)
