BroadLED™ Technology Improves Thermal Performance for Longer Lifetime and Higher Reliability

The iW7039 LED driver for LCD backlighting integrates 32 precision current sinks with advanced digital control technology to improve brightness control in direct backlit, High Dynamic Range (HDR) displays. The digital control block uses Dialog’sBroadLED™自适应开关技术，通过优化每个LED串上的电压降来改善热性能，同时实现与未固定LED的精确匹配。

iW7039还使用了Dialog的专利技术AnyMode™dimming, which offers comprehensive, simple and flexible options to improve HDR display picture quality. It allows continuous PWM signals or very narrow PWM burst signals that are fully synchronized to the video frame at the same or higher frequency. The PWM duty cycle can be updated in each video frame and with user-configurable tail or head delays. This provides more options to reduce motion blur and improve the contrast ratio.

AnyMode调光也有助于减少运动模糊所造成的人类视觉系统（HVS）产生高强度，短时脉宽调制脉冲。这将导致更快的淡出，并减少HVS的生理后像效应，这对于汽车仪表板显示非常重要。
