Problems solved by technology

However, we know that the thermal stability of current polarizing materials is poor. If you want to prepare quantum dots on the basis of polarizing materials, the preparation method of quantum dots must be low temperature, which actually limits the quality of quantum dot materials. selection and preparation range

Abstract

The invention provides a manufacturing method for a quantum dot polarizer. The manufacturing method for the quantum dot polarizer comprises the steps that a quantum dot layer and a polarizing layer are formed on different substrates to obtain a quantum dot diaphragm and a polarizing diaphragm respectively, and then the quantum dot diaphragm and the polarizing diaphragm are attached to each other to obtain the quantum dot polarizer. Due to the fact that the quantum dot polarizer is not obtained through sequential diaphragm forming on the same substrate, the quantum dot layer in the quantum dot polarizer can be prepared through both a high-temperature procedure and a low-temperature procedure, and the selection and preparation ranges of the quantum dot materials are widened. According to the quantum dot polarizer obtained through the method, the phenomenon of light polarization eliminating cannot occur while the color gamut coverage ratio of a display panel is increased.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a method for manufacturing a quantum dot polarizer. Background technique [0002] In order to meet people's demand for wide color gamut and high color saturation of displays, adding photoluminescent quantum dot devices into the backlight structure has become an effective choice for major display manufacturers. [0003] As a nanoscale material, quantum dots have obvious quantum confinement effect due to their narrow size (<10 nanometers). When excited by light, when the excitation energy level exceeds the band gap, electrons jump from the valence band to the conduction band, and The form of light energy is converted to form different colors; and different colors can be adjusted by controlling the size of the quantum dot itself. The color gamut of the display can be effectively improved by using the blue light of a backlight LED (light emitting diode, light emitting diode) lam...
