  • Publication number: 20240172493
    Abstract: An organic light emitting display device, in which a silicon semiconductor pattern is formed on a buffer layer, and light shielding patterns of a pixel driving thin film transistor and a switching thin film transistor are then formed in the same process by processing portions of the silicon semiconductor pattern such that the portions of the silicon semiconductor pattern have conductivity, is disclosed. In a procedure of forming the silicon semiconductor pattern for formation of the light shielding patterns, a silicon semiconductor pattern, which is disposed under a gate driving thin film transistor, may be formed simultaneously with the former silicon semiconductor pattern, without using an additional silicon semiconductor pattern formation procedure. Accordingly, stack structures, planar design, and processes are simplified and, as such, there are effects of preventing failure occurring due to processes while reducing tact time and costs.

  • Publication number: 20240154173
    Abstract: An energy storage device comprising a first electrode and a second electrode, wherein at least one of the first electrode and the second electrode comprises a self-supporting composite material film, a separator between the first electrode and the second electrode, and an electrolyte in contact with the first electrode, the second electrode, and the separator, wherein the electrolyte comprises at least one of a fluorine-containing cyclic carbonate, a fluorine-containing linear carbonate, and a fluoroether. The composite material film having greater than 0% and less than about 90% by weight of silicon particles, and greater than 0% and less than about 90% by weight of one or more types of carbon phases. At least one of the one or more types of carbon phases can be a substantially continuous phase that holds the composite material film together such that the silicon particles are distributed throughout the composite material film.
