  • Patent number: 11978911
    Abstract: The present invention relates to a three-dimensional structure electrode, a method for manufacturing same, and an electrochemical element including the electrode. The present invention is characterized by comprising: (a) an upper conductive layer and a lower conductive layer which have a structure constituting an assembly within which a conductive material and a porous nonwoven fabric including a plurality of polymeric fibers are three-dimensionally connected in an irregular and continuous manner, thereby forming a mutually connected porous structure; and (b) an active material layer forming the same assembly structure as the conductive layers and forming a three-dimensionally filled structure in which electrode active material particles are uniformly filled inside the mutually connected porous structure formed in the assembly structure, wherein the active material layer is formed between the upper conductive layer and the lower conductive layer.

  • Publication number: 20240134272
    Abstract: Provided are a method for preparing a pixel defining layer comprising applying and coating, pre-baking, exposing to light, developing, and post-baking of a photosensitive composition containing a colorant having a pigment with an average particle size of 100 nm or less, wherein the coated film generated after the post-baking has an optical density of 0.8/?m to 2.0/?m, a roughness of 3.0 nm or less, and no residue; and an organic light emitting display device comprising the pixel defining layer obtained by the method which has improved display reliability and lifetime as well as vivid colors.

  • Publication number: 20240085788
    Abstract: An object of the present disclosure is to improve display reliability and lifetime as well as vivid colors. When there remain residues in the washing part due to incomplete removal during the developing step, it can cause dark spots or pixel off due to the residues, and thus residue-free pixels can be formed by optimizing the temperature and time for developing. Additionally, when the amount of outgas in the panel after post-baking is 15 ppm or more, it may cause a reduction in luminance and lifetime due to pixel shrinkage. Therefore, in order to minimize the amount of outgas after completion of the post-baking process, the generation of outgas in the panel state can be minimized by generating sufficient fume in the post-baking step, in addition to forming clean pixels in the developing step.
