宽容™技术可提高高环境温度应用的热性能亚博国际官网平台网址

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 Dialog’s 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 Dialog’s 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.

随机调光还有助于通过产生高强度，短持续时间PWM脉冲来减少人类视觉系统（HV）引起的运动模糊。这导致淡出更快的淡出并降低了HV的生理余消效果，对于汽车仪表板显示很重要。
