Abstract: An electrolytic cell includes a cation exchange membrane, a cathode compartment, and an anode compartment. The cathode compartment includes a gas diffusion electrode and a flow channel element, in which the flow channel element is between the cation exchange membrane and the gas diffusion electrode, and has a plurality of flow channels arranged in parallel with each other. The anode compartment includes an anode mesh, in which the cation exchange membrane is between the anode mesh and the flow channel element. A distance between the anode mesh and the gas diffusion electrode is substantially equal to the sum of a first thickness of the cation exchange membrane and a second thickness of the flow channel element. The novel electrolytic cell can combine with a chloralkali electrolytic cell to deal with gaseous CO2 and produce products, e.g., synthesis gas, for other purposes.

Abstract: A switchable backlight module is disclosed. The switchable backlight module includes two light source modules arranged parallelly with respect to a plane. Each of the light source modules includes a turning film and a LGP. The LGP is of an edge-lit type arranged parallelly under the turning film. A light ray enters the LGP from a light incident side of the LGP, exits the LGP from a light emergent surface of the LGP, enters the turning film, and exits the turning film from a surface of the turning film away from the LGP. The light incident side of the LGP of one of the light source modules is perpendicular to the light incident side of the LGP of the other light source module. The switchable backlight module is in an anti-peeping mode having a narrow viewing angle when only an upper one of the light source modules emits light.

Abstract: An integrated circuit package including electrically floating metal lines and a method of forming are provided. The integrated circuit package may include integrated circuit dies, an encapsulant around the integrated circuit dies, a redistribution structure on the encapsulant, a first electrically floating metal line disposed on the redistribution structure, a first electrical component connected to the redistribution structure, and an underfill between the first electrical component and the redistribution structure. A first opening in the underfill may expose a top surface of the first electrically floating metal line.
