Electrowetting element including a compound comprising a plurality of colorant moieties and a linker. The plurality of colorant moieties includes a first colorant moiety having a first net dipole and a second colorant moiety having a second net dipole. The plurality of colorant moieties are linked by and disposed around the linker so that the first net dipole and the second net dipole at least partially cancel each other.

A display device includes: a light unit for emitting blue light; a color conversion panel on the light unit; a display panel between the light unit and the color conversion panel, the display panel comprising transistors; and column spacers between the transistors and the color conversion panel, the column spacers overlapping the transistors. The color conversion panel includes: a substrate; color conversion layers between the substrate and the display panel, the color conversion layers comprising semiconductor nanocrystals; a transmission layer between the substrate and the display panel; and polarization layers between the color conversion layers and the display panel and between the transmission layer and the display panel. The column spacers include a pigment that absorbs blue light.

Provided herein are methods for inducing cell death in a gram positive bacterium and methods for reducing the proliferation of a gram positive bacterium that include contacting a gram positive bacterium with a dye (e.g., an azo dye) and a TarO inhibitor. Also provided are methods of treating a subject having a gram positive bacterial infection that include administering to a subject having a gram positive bacterial infection a dye (e.g., an azo dye) and a TarO inhibitor. Also provided are compositions containing a dye (e.g., an azo dye) and a TarO inhibitor, and kits containing at least one of these compositions.
