Compound for organic electronic element, organic electronic element using the same, and an electronic device thereof

The present invention provides a novel compound capable of improving the luminous efficiency, stability and life of an element, an organic electronic element using the same, and an electronic device comprising same.

Compound for organic electronic element, organic electronic element using same, and electronic device comprising same

Provided is an implementation of a coloring pattern with a low moisture content on an electrode substrate to thereby improve display reliability and lifetime as well as vivid colors. That is, since when the moisture content is 50 ppm or more, it may cause a reduction in luminance and lifetime due to pixel shrinkage, in order to minimize the moisture content after completion of the post-baking process, the generation of moisture in the panel state is minimized by generating sufficient heat and time in the post-baking step, by including the colorant of the presently claimed subject matter.

Compound for organic electric element, organic electric element using same, and electronic apparatus thereof

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.

An object of the present disclosure is to implement a coloring pattern with a low amount of outgas on an electrode substrate to thereby increase reliability and lifetime of display as well as vivid colors of the same. That is, considering that 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, in order to minimize the amount of outgas after completion of the post-baking process, the generation of outgas in the panel state is minimized by generating sufficient fume in the post-baking step by way of including a colorant according to the present disclosure.

An object of the present disclosure is to implement a coloring pattern with a high optical density on an electrode substrate to improve display reliability and lifetime of a display as well as vivid colors. That is, the present disclosure relates to a composition and a method that can form the pattern of a pixel defining layer that can improve visibility and contrast by satisfying the optical density of 0.80/μm to 1.5/μm in the panel after post-baking treatment.

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/μm to 2.0/μm, 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.

Provided is a compound of Formula 1 capable of improving the light-emitting efficiency, stability, and lifespan of an organic electronic element, a composition comprising the same, an organic electronic element using same, and an electronic device thereof.

An organic electric element according to an embodiment of the present disclosure includes an anode, a cathode, and an organic material layer formed between the anode and the cathode. The organic material layer includes a compound of Formula 1. The driving voltage of the organic electric element can be lowered, and the luminous efficiency and life time of the organic electric element can be improved.

Organic electric element comprising compound for organic electric element and an electronic device thereof

Provided is a compound of Formula 1 that can improve the luminous efficiency, stability and life span of the element, an organic electronic element using the same, and an electronic device thereof.

Compound for organic electrical element, organic electrical element using same and electronic device thereof

Provided is a novel mixture capable of improving luminous efficiency, stability, and lifespan of an element, an organic electric element using the same, and an electronic device therefor.

Compound for organic electronic element, organic electronic element using same and electronic device thereof

Embodiments of the present invention relate to an organic electronic device capable of ensuring high luminous efficiency, low driving voltage and high heat resistance, and improving color purity or lifespan.

Organic electronic device

An object of the present disclosure is to implement a coloring pattern with a constant illuminance value on an electrode substrate to thereby increase display reliability and lifetime while reducing delamination of the hole transport layer (HTL) in the post-process. That is, when the roughness of the pattern after post-baking treatment is low, it may cause delamination of the hole transport layer (HTL) and a decrease in lifetime due to defective pixels, and thus a certain roughness can be obtained by minimizing the surface flow by leaving the substrate at a high temperature during post-baking treatment according to the present disclosure.
