AI Technical Summary

Problems solved by technology

However, it is difficult to synthesize group 13 and group 16. Therefore, it is not only difficult to realize the mass production of indium sulfide quantum dots, but also has the following disadvantages: compared with the conventional cadmium selenide, the guarantee of particle size uniformity or quantum yield (quantum yield) Yield, QY) is not ideal
[0009] Organic light-emitting diodes (OLEDs) and liquid crystal display devices (LCDs) each have their own advantages and disadvantages. Organic light-emitting diodes are very prominent in color rendition of red (red), green (Green), and blue (Blue), but , there is a problem that it is lower than the liquid crystal display device in terms of high resolution because of its low resolution, and on the contrary, the liquid crystal display device that can reflect high resolution has the problem of red, green and blue The problem that the reproducibility is lower than that of organic light-emitting diodes

Abstract

The present invention relates to a novel organic dot for a compensation film and a compensation film using the same, and an organic dot of the present invention relates to a new material which not only can replace existing quantum dots (QDs), but also can improve color reproduction power regarding R (red) and G (Green) and can enhance optical properties of materials such as LCD efficiency, color reproducibility and the like.

Description

technical field [0001] The present invention relates to a compensation film comprising organic dots and organic dots for the compensation film having a specific photoluminescence wavelength. Background technique [0002] Quantum dots are nanometer-sized semiconductor substances that exhibit quantum confinement effects. Quantum dots generate more intense light in a narrower wavelength range than conventional phosphors. [0003] The light emission of quantum dots occurs when electrons in the state of valence electrons float in the conduction band, and even in the case of the same substance, it exhibits the characteristic that the wavelength changes with the particle size. The smaller the size of the quantum dots, the more light can be emitted at shorter wavelengths. Therefore, light in a desired wavelength region can be obtained by adjusting the size. [0004] Arbitrary selection of the excitation wavelength also causes the quantum dots to emit light, and therefore, when var...
