Abstract
The invention discloses a quantum dot prism film which comprises a PET substrate. One surface of the PET substrate is provided with UV prisms arranged along the longitudinal direction thereof, wherein adjacent prism edges of any two adjacent UV prisms are arranged in the same line; a plurality of quantum dots are packaged in each UV prism; the UV prisms are formed by adding UV glue of the quantum dots to the PET substrate and carrying out pressing by a roller, and thus the quantum dot prism film is prepared. The processing process of the film is simple; the quantum dot prism film can be achieved by adding the UV glue of the quantum dots to the PET substrate and carrying out pressing by the roller, thereby providing richer and fuller color to a liquid crystal display module, improving color gamut, and saving materials and cost; and through utilizing the quantum dot prism film, the functions of optical gain and wavelength conversion can be achieved synchronously without additionally using the dot prism film.
Description
Technical field
The present invention relates to backlight arrangement technical field in liquid crystal display module, be specially a kind of quantum dot prism film.
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 prism film, 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 prism film, comprise PET base material, the UV prism of longitudinally arranging along it is provided with in described PET base material one side, the adjacent seamed edge of arbitrary neighborhood two UV prisms is arranged on same straight line, several quantum dots are all encapsulated in each UV prism, described UV prism, by adding the UV glue of quantum dot in PET base material, is formed by running roller impression, makes quantum dot prism film.
Preferably, in UV prism, quantum dot size specification is different.
Preferably, in UV prism, 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, by adding the UV glue of quantum dot in PET base material, can be realized by running roller impression, for liquid crystal display module provides more abundant and full color, improve colour gamut, save material and cost, use quantum dot prism film, synchronously can reach optical gain and wavelength converting function, without the need to additionally using quantum dot film.

As shown in Figure 2, a kind of quantum dot prism film, comprise PET base material 1, the UV prism 2 of longitudinally arranging along it is provided with in described PET base material 1 one side, the adjacent seamed edge of arbitrary neighborhood two UV prisms 2 is arranged on same straight line, all encapsulates several quantum dots 21 in each UV prism 2, and described UV prism 2 is by adding the UV glue of quantum dot in PET base material 1, formed by running roller impression, make quantum dot prism film.
Specific embodiment 1, with reference to Fig. 2,3, adds in UV prism glue by quantum dot 21 according to preset ratio, quantum dot can be encapsulated in prism 2 while UV glue is shaping.Technological process is as follows: be placed in PET base material 1 by the UV glue of band quantum dot, by transfer device, UV glue be processed into the UV prism 2 of longitudinally arranging along PET base material 1.
Specific embodiment 2, with reference to Fig. 4, PET base material 1 first arranges one deck quantum dot layer 3, the quantum dot 31 that specification of arranging in quantum dot layer 3 is different, then place UV glue at quantum dot layer 3, by transfer device, UV glue is processed into the UV prism 2 of longitudinally arranging along PET base material 1.
More than show and describe ultimate principle of the present invention and principal character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and instructions just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Claimed scope of the present invention is defined by appending claims and equivalent thereof.
