Quantum dots? Sounds familiar. Oh yes, quantum dots are being applied to new super-efficient solar cells. But wait, there’s more than just application to a particular technology involving the dots. Samsung Electronics have just previewed their latest quantum dot display to give us a glimpse of the future.
How are quantum dots different? Simple, really. Compared to OLEDS and LCDs they’re brighter, smaller, and generally better. Let’s not forget cheaper. How come? Now this is the tricky part. Let’s have a good chunk of the source article to explain matters. Hard science stuff is difficult to wrap around our brains, if you don’t mind.
“To make their prototype, the Samsung researchers start by coating a solution of quantum dots on a silicon plate and evaporating the solvent. Then they gently press a rubber stamp with a ridged surface into the quantum-dot layer, peel it off, and then press it on the desired glass or plastic substrate. This transfers stripes of quantum dots onto the substrate.
In a color display, each pixel contains red, green, and blue subpixels. These colors are combined in varying intensities to produce millions of colors. By using their stamping technique over and over, the researchers can create a repeated pattern of red, green, and blue stripes.”
But don’t get too excited, because quantum dots are several years away from becoming the new industry standard.
