Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
Example one
Referring to fig. 1, a schematic structural diagram of a color film substrate according to an embodiment of the present invention is shown.
The embodiment of the invention provides a color film substrate, wherein a low-refractive-index layer 11 is arranged on one side of the color film substrate close to a liquid crystal layer 21, and the refractive index of the low-refractive-index layer 11 is smaller than that of the liquid crystal layer 21.
In an embodiment of the present invention, as shown in fig. 1, the color filter substrate further includes an underlayer substrate 12, a black matrix 13 and a color resist layer 14 formed on the underlayer substrate 12; the low refractive index layer 11 is a flat layer covering the black matrix 13 and the color resist layer 14 and doped with a low refractive index material.
By adjusting the material ratio of the flat layer, a low refractive index material is doped in the original material, and the flat layer doped with the low refractive index material is formed on the black matrix 13 and the color resist layer 14, so that the refractive index of the flat layer doped with the low refractive index material is smaller than that of the liquid crystal layer 21.
In another embodiment of the present invention, as shown in fig. 2, the color filter substrate further includes a substrate 12, a black matrix 13 and a color resist layer 14 formed on the substrate 12, and a flat layer 15 formed on the black matrix 13 and the color resist layer 14, and the low refractive index layer 11 is formed on the flat layer 15.
A flat layer 15 is formed on the black matrix 13 and the color resist layer 14, and then a low refractive index layer 11 is formed on the flat layer 15, and the refractive index of the low refractive index layer 11 is smaller than that of the liquid crystal layer 21. The material of the planarization layer 15 is the conventional planarization layer material, and the refractive index of the planarization layer 15 is equal to the refractive index of the liquid crystal layer 21.
Referring to fig. 3, a schematic diagram of a principle of implementing peeping prevention of a color film substrate according to an embodiment of the present invention is shown.
Assuming that the critical angle of total reflection is C, when the incident angle of light is greater than the critical angle of total reflection C, total reflection occurs, and the light cannot penetrate through the color film substrate, so that peeping prevention can be realized; when the incident angle of the light is smaller than the critical angle of total reflection C, as shown in the incident angle B in fig. 3, the light can directly penetrate through the color filter substrate.
Wherein the refractive index of the liquid crystal layer 21 is n1The refractive index of the low refractive index layer 11 is n2According to the principle of total optical reflection, the critical angle of total reflection C is arcsin (n)2/n1)。
It should be noted that, the main transparent layers in the color filter substrate include the substrate 12, the color resist layer 14 and the low refractive index layer 11, and in order to ensure the transmittance of the display panel to be maximized, the refractive indexes of the transparent layers should be kept as consistent as possible, so that the brightness loss caused by the reflection of light at the interface between the two transparent layers can be reduced. Therefore, the refractive indices of the base substrate 12, the color resist layer 14 and the liquid crystal layer 21 should be kept uniform except for the low refractive index layer 11, and the refractive index thereof is generally 1.5.
As shown in fig. 3, when the incident angle of the light is B, since the incident angle B is smaller than the critical angle C of total reflection, the light may be refracted at the interface between the liquid crystal layer 21 and the low refractive index layer 11, and when the refracted light reaches the interface between the low refractive index layer 11 and the color resistance layer 14, the light may be refracted again, according to the principle that the light path is reversible, it can be seen that the incident light is only translated after being refracted twice, the exit angle is not changed, and the exit angle refers to the angle between the exit light and the normal F perpendicular to the color film substrate.
The light is emitted in a direction away from the liquid crystal layer 21 toward the color film substrate, and the emitting angle of the light is the same as the incident angle, when the incident angle of the light is smaller than the total reflection critical angle C, the light can directly penetrate through the color film substrate, and the corresponding emitting angle is also smaller than the total reflection critical angle C. Therefore, when the angle between the position of the user and the normal F perpendicular to the color film substrate is smaller than the total reflection critical angle C, the contrast is normal, and the information displayed by the display device can be normally observed, that is, the visual angle of the user is smaller than the total reflection critical angle C; when the angle between the position of the observer and the normal F perpendicular to the color film substrate is larger than the critical angle C of total reflection, the contrast is smaller than 10, and the observer cannot observe the information displayed by the display device, so that the purpose of information protection is achieved.
For example, the refractive index of the liquid crystal layer 21 is 1.5, and if the peep prevention is to be implemented at an angle greater than 45 °, the refractive index of the low refractive index layer 11 is 1.0605, and at this time, when the angle between the position where the observer is located and the normal F perpendicular to the color film substrate is greater than 45 °, the corresponding information cannot be observed, and the peep prevention is implemented; correspondingly, to achieve a privacy of more than 30 °, the refractive index n of the low refractive index layer 112Refractive index n with liquid crystal layer 211The ratio between should be 0.5; to achieve privacy of greater than 60 °, the refractive index n of the low refractive index layer 112Refractive index n with liquid crystal layer 211The ratio between should be 0.866.
It should be noted that the schematic diagram of the peeping prevention shown in fig. 3 corresponds to the color filter substrate shown in fig. 1, and for the color filter substrate shown in fig. 2, because the low refractive index layer 11 is formed on the planarization layer 15, the refractive index of the planarization layer 15 is equal to the refractive index of the liquid crystal layer 21, when the incident angle B of the light is smaller than the critical angle C of total reflection, the light will be refracted at the interface between the liquid crystal layer 21 and the low refractive index layer 11, when the refracted light reaches the interface between the low refractive index layer 11 and the planarization layer 15, the light will be refracted again, and the exit angle is equal to the incident angle, and because the refractive indexes of the planarization layer 15, the color resistance layer 14 and the substrate 12 are equal, the light exiting to the planarization layer 15 can directly pass through the color resistance layer 14 and the substrate 12.
The color filter substrate shown in fig. 1 and fig. 2 only has a second refraction interface different from each other, the second refraction interface in fig. 1 is an interface between the low refractive index layer 11 and the color resist layer 14, and the second refraction interface in fig. 2 is an interface between the low refractive index layer 11 and the planarization layer 15. The anti-peeping principle corresponding to the color film substrate shown in fig. 2 can be correspondingly shown in fig. 3.
In the embodiment of the present invention, the material of the low refractive index layer 11 is an organic mixture.
Through adjusting the refractive index of the low refractive index layer 11, peeping prevention in different angle ranges can be realized, and when the refractive index n of the low refractive index layer 112Refractive index n with liquid crystal layer 211The smaller the ratio therebetween, the smaller the corresponding viewing angle. By reducing the refractive index of the low refractive index layer, the viewing angle of the display device is correspondingly reduced, when the display device is viewed in the normal direction (that is, when the angle between the position of the user and the normal F is 0 °), the display information of the display device can be normally distinguished, and as the angle between the position of the user and the normal F increases, when the angle between the position of the user and the normal F is larger than the critical angle C for total reflection, the observer cannot observe the information displayed by the display device.
In the embodiment of the invention, the low-refractive-index layer is arranged on one side of the color film substrate close to the liquid crystal layer, and the refractive index of the low-refractive-index layer is smaller than that of the liquid crystal layer.

Specifically, the black matrix 13 is first fabricated on the substrate 12, then the R, G, B three-color photoresist is sequentially coated in the gap of the black matrix 13, and the photoresist layer 14 is obtained after exposure, development and baking.
In the embodiment of the present invention, after the black matrix 13 and the color resist layer 14 are formed, the low refractive index layer 11 is formed, and the refractive index of the low refractive index layer 11 is smaller than that of the liquid crystal layer 21.
Wherein the low refractive index layer 11 is formed by a coating process.
In one embodiment of the present invention, a planarization layer is formed on the black matrix and the color resist layer; the planar layer is doped with a low refractive index material.
As shown in fig. 1, a low refractive index material is doped into an original material by adjusting a material ratio of the flat layer, the flat layer doped with the low refractive index material is formed on the black matrix 13 and the color resist layer 14, and the flat layer doped with the low refractive index material is used as the low refractive index layer 11.
In another embodiment of the present invention, a planarization layer is formed on the black matrix and the color resist layer; forming a low refractive index layer on the planarization layer.
As shown in fig. 2, a flat layer 15 is formed on the black matrix 13 and the color resist layer 14, and then the low refractive index layer 11 is formed on the flat layer 15; the material of the flat layer 15 is the existing flat layer material.
In the embodiment of the invention, the black matrix and the color resistance layer are formed on the substrate, and then the low-refractive-index layer is formed, wherein the refractive index of the low-refractive-index layer is smaller than that of the liquid crystal layer. Based on the principle of optical total reflection, at the interface of the liquid crystal layer and the low refractive index layer, when the incident angle of light is greater than the critical angle of total reflection, total reflection can occur, the light cannot penetrate through the color film substrate, the display device does not display information, information leakage can be effectively prevented, and the information safety is improved.
