Ching Wan Tang #AsianPacificAmericanHeritageMonth #APAHM #AAPIHM
Today we are celebrating Ching Wan Tang, who helped invent OLED technology.
Tang holds a PHD in physical chemistry from Cornell University. Following graduation, he worked at Eastman Kodak, where he was honored with a fellowship.
Born in Hong Kong, Tang received his higher education in Canada and the United States and joined Eastman Kodak in 1975. After hiring Van Slyke, they applied the organic heterojunction, a bilayer structure of an electron donor and an electron acceptor invented by Tang, to various applications including OLEDs. OLEDs can be used wherever LCDs are used. They are thinner, lighter, provide superior brightness and color, and offer ultra-fast response time for functions such as refreshing and on-off switching. Unlike LCDs that rely on a backlight that passes through color filters to produce light, OLED screens utilize luminescent organic materials to make their own light.
The first OLED product was a display for a car stereo, commercialized by Pioneer in 1997.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
Have an amazing project to share? The Electronics Show and Tell is every Wednesday at 7pm ET! To join, head over to YouTube and check out the show’s live chat – we’ll post the link there.
