Wide color gamut based on quantum dot material LED display Yes Display technology The main trend of development, at the same time, how to achieve without DBEF LED backlight Exiting the P-polarized light, breaking the monopoly of the 3M Company in the United States, the application of white LED, especially the quantum dot light-emitting diode (QLED) backlight display It is very important and has become one of the key points in the development of a new generation of LED display technology.
In the present invention, the quantum rod has the characteristics of both wide color gamut and linearly polarized light, and is expected to become the key core material of a new generation of wide color gamut, low cost (without DBEF) LED display technology and break through the bottleneck of the existing LED display technology.
Therefore, a new generation of wide color gamut LED display with high efficiency, high stability quantum rod active brightness enhancement film composite material application research and development of new quantum rod directional arrangement of brightness enhancement film preparation process, analysis of its linear polarization optical properties, high The stability of the quantum rod brightness enhancement film mass production technology is important and urgent, with important theoretical significance and engineering value.
Up to now, there is no literature to study the highly polarizability of oriented QDs. The present invention is based on the finite difference time-domain method for the study of polarization properties of metallic nano-materials. The effects of different sizes, aspect ratios, radial and axial Duty ratio, different materials, angle of incidence and other factors under the polarization performance, put forward a directional arrangement of quantum materials applied to LED brightness enhancement film, this active brightness enhancement film can be achieved in the absence of DBEF LED backlight P Polarized light, and S-polarized light are mostly reflected phenomenon.
In the present invention, the aligned and aligned quantum material can emit polarized light and the periodic metallic nano material has a strong polarization effect. In addition to obtaining the polarized light of the light source band, the polarized light of different wavelength band excited by the light source of the quantum material can also be obtained, Ultimately with maximum efficiency at the same time blue, red and green polarized light.
The present invention belongs to the technical field of optical film manufacturing and discloses an active brightness enhancement film comprising a polymer film layer containing a quantum material and a polymer film layer containing a metal nano material, , Periodically arranged, the metal nanomaterials are oriented, periodically arranged, the quantum material is perpendicular to the arrangement direction of the metal nanomaterials (as shown) 1 is a quantum rod polymer film layer, 2 is a metal nanorods Polymer film layer.
The present invention provides an active brightness enhancement film based on quantum materials and metallic nanomaterials. The unique arrangement of quantum materials and metallic nanomaterials in the polymer layer can meet the requirements of the prior art and can be better applied to the QLED backlight Show up.
