Description
The iW7038 LED driver for LCD backlighting integrates 16 precision current sinks with advanced digital control technology to improve brightness control in High Dynamic Range (HDR) displays. The digital control block uses Renesas' BroadLED™ adaptive switch technology, improving thermal performance by optimizing the voltage drop across each LED string while enabling precision matching with unbinned LEDs.
The iW7038 also uses Renesas' patented 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 dimming also helps reduce motion blur caused by the Human Visual System (HVS) by generating high intensity, short duration PWM pulses. This results in faster fade out and reduces the physiological afterimage effects of the HVS, important for automobile dashboard displays.
