Abstract
The invention discloses a quantum dot diffusion membrane comprising PET base material. One surface or two surfaces of the PET base material is/are provided with a UV diffusion membrane. Multiple quantum dots are packaged in the UV diffusion membrane. The UV diffusion membrane is transfer-printed on the PET base material via UV glue with additional arrangement of the quantum dots. The quantum dot diffusion membrane is simple in manufacturing technology. The UV diffusion membrane is transfer-printed on the PET base material via UV glue with additional arrangement of the quantum dots and packaging of the quantum dots is completed so that richer and fuller colors are provided for a liquid crystal display module group, color gamut is enhanced, material and cost are saved, and optical atomization, gain and wavelength conversion functions of the quantum dot diffusion membrane can be achieved simultaneously without additional use of quantum dot membranes.
Description
Technical field
The present invention relates to backlight arrangement technical field in liquid crystal display module, be specially a kind of quantum dot diffusion barrier.
Background technology
Current traditional LC D backlight uses blue-ray LED to fill yellow fluorescent powder and realizes white light.Quantum dot has discrete band structure, has function blue light being converted into ruddiness and green glow.The light emitting diode with quantum dots be made up of quantum dot, be the U.S., Korea S and Belgian scientist hand in hand research and development shield based on the Active Matrix LCD At of light emitting diode with quantum dots (QLED), compared with current display screen, new display screen, while substantially increasing brightness and picture vividness, also reduces energy consumption.
Current quantum dot mainly contains two kinds of application in the opto-electronic device, and a kind of is the application-quantum dot film of film; Another kind is the application of lamp, namely in LED and fluorescent tube, replaces fluorescent powder with quantum dot.These two kinds of devices all need to keep away oxygen to quantum dot and keep away tide encapsulation.The structure of general quantum dot film as shown in Figure 1 at present: quantum dot is attached directly to PET base material film surface.
Summary of the invention
Technical matters solved by the invention is to provide a kind of quantum dot diffusion barrier, and structure is simple, improves the colorfulness of emergent light under the condition not changing backlight miscellaneous part better.
Technical matters solved by the invention realizes by the following technical solutions:
A kind of quantum dot diffusion barrier, comprises PET base material, is provided with UV diffusion barrier, all encapsulates several quantum dots in UV diffusion barrier at described PET base material one or both sides, and described UV diffusion barrier is transferred in PET base material by the UV glue adding quantum dot.
Preferably, in UV diffusion barrier, quantum dot size specification is different.
Preferably, in UV diffusion barrier, the particle size range of quantum dot is 3 ~ 10nm.
Preferably, described PET base material thickness range is at 25 ~ 250um.
Making technology of the present invention is simple, encapsulation PET base material completed to quantum dot is transferred in by adding the UV glue of quantum dot, for liquid crystal display module provides more abundant and full color, improve colour gamut, save material and cost, using quantum dot diffusion barrier, synchronously can reaching optics atomization, gain and wavelength converting function, without the need to additionally using quantum dot film.
