Description
Technical Field
The invention relates to the technical field of display and illumination, in particular to a quantum dot diffusion plate with high brightness, shielding and low deformation, and a preparation method and application thereof.
Background
The light diffusion plate is characterized in that a light diffusion plate is formed by adding a light diffusion agent into a transparent resin base material to change the traveling path of light by utilizing the physical phenomenon of refraction, reflection and scattering when light encounters two media with different refractive indexes in the traveling path through a chemical or physical means, so that the incident light is fully dispersed to generate the optical diffusion effect.
The quantum dot material has the characteristics of wide excitation spectrum, narrow emission spectrum, high color purity and good light stability, and can improve the optical performance of the diffusion plate. The quantum dot diffusion plate combines the quantum dot technology and the light diffusion plate technology, and has excellent optical display effect.
The quantum dot diffusion plate on the market at present is mainly prepared by the following methods: (1) the quantum dots are printed on the diffusion plate by adopting a printing method, but the printing manufacturing process is very complicated and is difficult to apply to industrial continuous production; (2) the quantum dot film is put into use in a way of being matched with a common diffusion plate, or the film is coated by adopting a coextrusion method, but for large-size display equipment, the problem of display distortion caused by the inconsistency of linear expansion coefficients of the quantum dot film and the diffusion plate is easy to occur.
At present, display equipment is thinner and thinner, the size is bigger and bigger, the size of the corresponding diffusion plate is bigger and bigger, and the diffusion plate of the quantum dots with bigger size is easy to resist deformation, so that the diffusion plate is not enough to cause expansion and deformation, and the display is caused to be problematic. This also requires higher and higher deformation of the diffuser plate, and the quantum dot diffuser plate needs to have excellent deformation resistance in addition to maintaining high brightness and high haze.
Disclosure of Invention
In order to overcome the defects in the prior art, the invention provides the quantum dot diffusion plate with high brightness, shielding and low deformation, the transparent glass fiber with the refractive index within a certain range is combined with the quantum dot master batch, the transparent glass fiber is introduced into the diffusion plate, and the glass fiber is used as a light diffusion medium, so that the quantum dot diffusion plate has excellent deformation resistance, high brightness and high haze.
The invention also aims to provide a preparation method of the quantum dot diffusion plate.
The invention also aims to provide application of the quantum dot diffusion plate.
In order to solve the technical problems, the invention adopts the technical scheme that:
a high-brightness shielding and low-deformation quantum dot diffusion plate comprises the following components in parts by weight:
100 parts of a resin base material, namely,
5-18 parts of glass fiber,
0.1 to 1 part of quantum dots,
0.2 to 1 part of a weather resistant agent,
0.3 to 2 parts of an antioxidant,
1-2 parts of a lubricant;
the refractive index of the glass fiber is 1.4-1.58, and the average diameter is 7-17 μm.
The inventor researches and discovers that the linear expansion coefficient of the quantum dot light diffusion plate can be remarkably reduced by selecting the glass fiber as the light diffusion medium and introducing the glass fiber into the diffusion plate and combining the quantum dot technology, and the quantum dot light diffusion plate is deformation-resistant, so that the large-size quantum dot diffusion plate has excellent size stability and is not easy to deform.
In the quantum dot diffusion plate of the present invention, the glass fiber serves as both a deformation resistance improving aid and a light diffusion medium. Under the conditions that the refractive index of the glass fiber is 1.4-1.58 and the average diameter is 7-17 mu m, the addition of the glass fiber can ensure that the quantum dot diffusion plate keeps high brightness and high haze.
The brightness and the haze in the quantum dot diffusion plate have a relationship of mutual drag and influence.

haze: testing according to the GB/T2410-2008 standard method;
coefficient of linear expansion: the test is carried out according to GB/T2572-.
The test results of examples 1 to 18 are shown in Table 3, and the test results of comparative examples 1 to 6 are shown in Table 4.
TABLE 3 test results of examples 1 to 18
Generally, the higher the brightness value of the quantum dot diffusion plate is, the better the light emitting and displaying effects are; the higher the haze value is, the better the shielding property is, namely, the electronic elements in the display can be shielded, and the display effect in the light emitting process is not influenced; the lower the linear expansion coefficient, the better the deformation resistance. It should be noted that, for the quantum dot diffusion plate, the luminance and the haze value need to be combined to comprehensively evaluate the light emitting and displaying performance.
In the present application, it is considered that the luminance of 3900cd or more and the haze of 90% or more are the standards of acceptability, and the luminance of 4500cd or more and the haze of 93.5% or more are the standards of better.
According to the test results in table 1, the quantum dot diffusion plates prepared by the embodiments of the present invention all satisfy: the linear expansion coefficient is less than or equal to 50 mu m/(m DEG C), the brightness is more than or equal to 3900cd, the haze is more than or equal to 90 percent, and the high-temperature-resistant optical fiber has excellent deformation resistance, high brightness and high haze.
In examples 1 to 6, the linear expansion coefficients are all close, and the quantum dot diffusion plates of examples 1 to 3 have relatively better overall brightness and haze. Therefore, the glass fiber preferably has a refractive index of 1.5 to 1.57 and an average diameter of 8 to 15 μm.
According to the embodiments 1, 8 and 9, good light emitting effect and deformation resistance can be achieved for different transparent resin base materials, wherein when the resin base material is GPPS, the brightness of the quantum dot diffusion plate is higher.
According to the embodiments 1 and 10 to 12, when the adding amount of the glass fiber is 8 to 15 parts by weight, the prepared quantum dot diffusion plate has excellent brightness and haze. Although the linear expansion coefficient of the quantum dot diffusion plate of example 12 is relatively low, the luminance value thereof is reduced by 300cd or more compared to examples 1 and 11, and thus the overall performance of the quantum dot diffusion plates of examples 1 and 11 is more excellent.
TABLE 4 test results for comparative examples 1 to 6
The refractive index of the glass fiber used in comparative example 1 was too low, and the brightness of the prepared quantum dot diffusion plate was poor. In comparative example 2, the average diameter of the glass fiber is too small, and the glass fiber is more densely distributed in the quantum dot diffusion plate under the same quality, so that the haze of the quantum dot diffusion plate is qualified, but the brightness is poor.
In comparative example 3, the content of the glass fiber is too small to have an effective light diffusion effect, and the light refraction is not enough, so that the brightness and the haze of the quantum dot diffusion plate are poor, and the quantum dot diffusion plate cannot have an obvious deformation resistance improvement effect, and the linear expansion coefficient of the quantum dot diffusion plate is high. In comparative example 4, the content of glass fiber was too large, and the luminance of the quantum dot diffusion plate was only 2560cd, which is far lower than that of the example, although the deformation resistance was excellent.
In comparative example 5, the quantum dot diffusion plate did not contain glass fiber, but used a conventional light diffuser (nano silica), and the quantum dot diffusion plate had an extremely high linear expansion coefficient and poor deformation resistance.
In comparative example 6, the quantum dot master batch was not prepared, but all the components were directly mixed. The quantum dots are subjected to heat loss in the extrusion process, so that the brightness of the quantum dot diffusion plate is poor.
