With the best LED face masks now repping technology like near-infrared light and acne-fighting blue light, the skincare industry only seems to be gaining momentum. Many of us like to think we’ve ...

Typically referred to as light therapy or LED face masks, these contraptions use light-emitting diodes to shine light at specific wavelengths onto the skin for various purposes like reducing ...

[导读]PWM控制技术就是对脉冲宽度进行调制的技术。即通过对一系列的脉冲宽度进行调制，来等效地获得所需要的波形。采样控制理论中有一个重要结论:冲量相等而形状不同的窄脉冲加在具有惯性的环节上时,其效果基本相同。 PWM(脉冲宽度调制)是用脉冲来输出 ...

Siflower SF21H8898 SoC features a quad-core 64-bit RISC-V processor clocked at up to 1.25 GHz and a network processing unit (NPU) for handling traffic and is designed for industrial-grade gateways, ...

Abstract: This letter introduces an analog pulse width modulation (A-PWM) pixel circuit for progressive-emission (PE) active-matrix micro light-emitting diode (AMμLED) displays, which is enabled by a ...

[导读]在这个项目中，我将为WLED构建一个RGB PWM LED驱动程序。您可以使用此项目无线驱动12v RGB LED条。这个项目是WLED兼容，这使得控制容易得多。你可以用它驱动高达100w的RGB LED条。WLED运行在XIAO ESP32C3上，LED驱动器使用IRLFZ44N逻辑级MOSFET。让我们开始建造吧。

This is one for sports fans to keep an eye on. One of the other major reveals at CES was the introduction of Hisense's RGB mini-LED backlit TV, the 116-inch UX. Hisense says the new tech will ...
