Novel perovskite growth method leads to ultrahigh-resolution micro-LED displays

Microscale light-emitting diodes (micro-LEDs) are emerging as a next-generation display technology for optical communications, augmented and virtual reality, and wearable devices. Metal-halide perovskites show great potential for efficient light emission, long-range carrier transport, and scalable manufacturing, making them potentially ideal candidates for bright LED displays. However, manufacturing thin-film perovskites suitable for micro-LED displays faces serious challenges. For example, thin-film perovskites may exhibit inhomogeneous light emission, and their surfaces may be unstable when subjected to lithography. For these reasons, solutions are needed to make thin-film perovskites compatible with micro-LED devices. Recently, a team of Chinese researchers led by Professor Wu Yuchen at the Technical Institute of Physics and Chemistry of the Chinese Academy of Sciences has made significant strides in overcoming these challenges. The team has developed a novel method for the remote epitaxial growth of continuous crystalline perovskite thin films. This advance allows for seamless integration into ultrahigh-resolution micro-LEDs with pixels less than 5 μm.

The first test for our WLED board codename "Sparkle Motion" 🌈💖💡 … 🐇⏳🌌

We got our WLED-friend PCBs today, and we only made one mistake: the wrong resistor on the 3.3V feedback line. Now that it's fixed, the board seems to work great with the latest version of WLED

We are checking all 4 signal outputs with this handy 256-LED grid that sits on our desk. Next, we will test the onboard IR receiver, USB PD, I2S microphone, extra I/O pins, and I2C. We'll also do an Arduino IDE board definition in case folks want to use it as a generic ESP32-to-LED-driver board. We're calling the board "Sparkle Motion" for now, but if you have other naming ideas, let us know - if we pick your name, you get a free board

Sign up, coming soon.

Here's a controversial take: People need to stop whining about streetlights no longer being orange.

The human retina in much more sensitive to blue light.

When you're driving, cycling, walking, etc. at night... you want to be more alert. It is a streetlight's one and only job to provide you with a level of light that makes night-time travel safer for you and those around you.

Blue light keeps you alert, and it allows you to perceive more details with the same or less amount of light, compared to a warm light source.

People complain that the blue and white LEDs in streetlights are unsavory and uncomfortable... GOOD! You shouldn't feel comfortable and cozy while driving at night. You should be awake and alert.

"Walnut" Speaker by Penguin DIY

The speaker itself a miniature little device the size of a… well, walnut. Made from the walnut’s shell, it packs all the necessary components inside, including a mini battery, amp, driver, Bluetooth module, USB-C port, and even buttons and LEDs to control playback or increase/decrease the volume.

Engineers develop first deep-UV microLED display chips for maskless photolithography

In a breakthrough set to revolutionize the semiconductor industry, the School of Engineering of the Hong Kong University of Science and Technology (HKUST) has developed the world's first-of-its-kind deep-ultraviolet (UVC) microLED display array for lithography machines. This enhanced efficiency UVC microLED has showcased the viability of a lowered cost maskless photolithography through the provision of adequate light output power density, enabling exposure of photoresist films in a shorter time. Conducted under the supervision of Prof. Kwok Hoi-Sing, Founding Director of the State Key Laboratory of Advanced Displays and Optoelectronics Technologies at HKUST, the study was a collaborative effort with the Southern University of Science and Technology, and the Suzhou Institute of Nanotechnology of the Chinese Academy of Sciences.

More Sparkle Motion testing - 24V Neon Neopixel Tubes ✨🌈

This chonky neopixel tube is a treat with full, smooth color all the way around - but it's also a real pain to drive, given it requires 24V power. Or at least it would be if we didn't have this Sparkle Motion

board we are testing! With USB PD support, it's easy to plug the board into a USB C laptop power supply that can provide 20V at up to 5A - even though it's under 24V, we've found the LEDs are just as bright. Looks great, we're going to keep testing and get these boards ordered, hopefully before the year's end!
