IW7039 Integrated Circuit Chip
High Precision 32-Channel LED Backlighting Driver With Integrated Current Sinks For HDR LCD Displays
Product Overview
The IW7039 LED driver for LCD backlighting integrates 32 precision current sinks with advanced digital control technology to enhance brightness control in direct backlit, High Dynamic Range (HDR) displays. The digital control block utilizes Renesas' BroadLED™ adaptive switch technology, improving thermal performance by optimizing voltage drop across each LED string while enabling precision matching with unbinned LEDs.
The IW7039 also employs Renesas' patented AnyMode™ dimming, offering comprehensive, simple, and flexible options to improve HDR display picture quality. It supports continuous PWM signals or very narrow PWM burst signals fully synchronized to the video frame at the same or higher frequency. The PWM duty cycle can be updated in each video frame with user-configurable tail or head delays, providing more options to reduce motion blur and improve contrast ratio.
