Therefore, the present application provides a color film substrate, a liquid crystal display panel and a method for manufacturing the color film substrate to solve the above problems.
Fig. 1 is a schematic structural diagram of a color film substrate provided in the present application. In one embodiment, the color filter substrate 1 includes: the color filter substrate comprises a first substrate 11, a color resistance layer 12 (not shown in the figure), a black matrix 124 and a first polarizer 13, wherein an up-conversion luminescent material layer 136 is arranged in the first polarizer 13, and the up-conversion luminescent material layer 136 forms a visible laser spot of a laser pen under the irradiation of infrared laser, so that the visible angle of the color filter substrate 1 is increased. The color resistance layer 12 is: the red/blue/ green resists 121, 122, 123 or 121/122/123/white resist (not shown) are not limited to the red/blue/ green resists 121, 122, 123 shown in fig. 1.
Further, the upconversion luminescent material layer 136 is divided into: an up-conversion red light material and an up-conversion green light material; the up-conversion luminescent material can prevent light from being absorbed, particularly infrared light with energy lower than visible light energy, the infrared light is non-visible light, and when near-infrared light emitted by the laser pen irradiates on the liquid crystal display panel, a display effect that light beams interfere a display area cannot be generated between the laser pen and the liquid crystal display panel. Therefore, the up-conversion red light material and the up-conversion green light material have certain preset wavelength length for the wavelength of the infrared laser. The preset wavelength length of the up-conversion red light material is as follows: 960 nm; the preset wavelength lengths of the up-conversion green light material are as follows: 966 nm.
Furthermore, the up-conversion red light material adopts Tm doped with sensitizing ions3+Or Yb3+BaY of (1)2F8A crystal; the up-conversion green light material adopts Er doped with sensitizing ions3+ZnWO (2)3And (4) crystals. Since the thickness of the up-conversion luminescent material layer 136 has a certain influence on the color filter substrate 1, that is, if the up-conversion luminescent material layer 136 is too thick, the polarization effect of the color filter substrate 1 is influenced, and the lightness and thinness of the color filter substrate 1 are also influenced; if the upconversion luminescent material layer 136 is too thin, the infrared laser reflection effect of the upconversion luminescent material layer 136 cannot be exerted. Therefore, the upconversion luminescent material layer 136 further has a certain preset thickness, and the preset thickness of the upconversion luminescent material layer 136 is: 4um-8 um.
Further, the first polarizing plate 13 is formed of: a release film 131, a Pressure Sensitive Adhesive (PSA) 132, a first Triacetyl Cellulose (TAC) film 133, a Polyvinyl Alcohol film (PVA) 134, a second Triacetyl Cellulose (TAC) film 135, an upconversion luminescent material layer 136, a Polyethylene Terephthalate (PET) film 137, and scattering particles 138 are sequentially stacked, and since the scattering particles 138 are covered on a side of the Polyethylene Terephthalate film 137 facing away from the upconversion luminescent material layer 136, when an outgoing light passes through the first polarizer 13, visibility of a laser pen is enhanced, and thus, display quality of the color filter substrate 1 is improved. The second polarizer (not shown in the figure) is formed by sequentially laminating a pressure sensitive adhesive, a first cellulose triacetate film, a polyvinyl alcohol film, a second cellulose triacetate film, a polyethylene terephthalate film and scattering particles, and is shown in figure 3 in detail.
Specifically, the release film 131 is mainly used for isolating and protecting the pressure-sensitive adhesive 132; the pressure-sensitive adhesive 132 is an adhesive sensitive to pressure, resistant to high temperature and moisture, and components for preventing ultraviolet rays from passing through can be added into the pressure-sensitive adhesive 132 to prepare an ultraviolet-proof polarizer; the polyvinyl alcohol film 134 is a core layer of the polarizer, mainly plays a role of polarization, and has low viscosity, but the polyvinyl alcohol film 134 is very easy to hydrolyze, and after being subjected to extension treatment, the polyvinyl alcohol film 134 can be quickly deformed, shrunk, loosened and faded in a warm environment, has low strength, is brittle and breakable, and is inconvenient to use and process, so that, in order to protect the physical properties of the polarizer 13 and prevent the retraction of the polyvinyl alcohol film 134, triacetyl cellulose films (133, 135) having high light transmittance, good water and oxygen resistance and certain mechanical strength are compounded on two sides of the polyvinyl alcohol film 134, namely the first triacetyl cellulose film 133 and the second triacetyl cellulose film 135, so as to protect the polyvinyl alcohol film 134. In addition, in one embodiment, instead of the color resist layer 12, a color polarizer may be formed by coloring the pressure sensitive adhesive 132, the cellulose triacetate films (133, 135) or the polyvinyl alcohol film 134.
Further, according to other usage requirements of users, a transmissive film, a reflective film or a transflective film may be further disposed on a side of the first polarizer 13 away from the scattering particles 138 to form a transmissive polarizer, a reflective polarizer or a transflective polarizer.
Referring to fig. 2, in another embodiment of the present application, the color filter substrate 1' includes: the color resistance layer 12 ', the black matrix 124 ', the second polarizer 13 ' and the second substrate 11 ', the upconversion luminescent material layer 112 ' is disposed in the second substrate 11 ', and the upconversion luminescent material layer 112 ' forms a visible laser spot of a laser pen under the irradiation of infrared laser, so that the visible angle of the color film substrate 1 is increased.
Further, the second substrate 11 ' is composed of a substrate 111 ' and the upconversion luminescent material layer 112 ', and the upconversion luminescent material layer 112 ' has all the characteristics of the upconversion luminescent material layer 112 ' described above.
The application also provides a liquid crystal display panel, which comprises the characteristics of all the color film substrates 1, an array substrate 3 arranged right opposite to the color film substrate' and a liquid crystal layer 2 arranged between the color film substrate 1 and the array substrate 3. A plurality of liquid crystal molecules 21 are arranged in the liquid crystal layer 2.
Referring to fig. 4, the present application further provides a method for manufacturing a color film substrate, including the following steps: s10, providing a first substrate or a second substrate; s20, if the second substrate base plate is adopted, depositing an up-conversion luminescent material layer on the second substrate base plate; s30, depositing a color resistance layer and a black matrix on one side of the first substrate base plate and/or the second substrate base plate; s40, attaching a first polarizer or a second polarizer to one side of the first substrate and/or the second substrate close to the color resistance layer; s50, if the polarizer is the first polarizer, depositing an up-conversion luminescent material layer on one side of the first polarizer, which is far away from the substrate base plate.
