In order to solve the problem of poor optical effect of the liquid crystal display due to yellow and uneven color of white light emitted into the liquid crystal display panel by the backlight module in the conventional liquid crystal display, the present embodiment provides a liquid crystal display.

Referring to fig. 1, fig. 1 is a schematic structural diagram of a liquid crystal display provided in this embodiment, where the liquid crystal display includes: a backlight module 10 and a liquid crystal display panel 11 disposed at the light-emitting side of the backlight module 10.

In this embodiment, the backlight module 10 includes: the light guide plate 101, the blue light source 102 disposed on the light incident surface side (the surface facing the blue light source 102 in fig. 1) of the light guide plate 101, and the optical film 103 disposed on the light emitting surface side (the surface facing the optical film 103 in fig. 1) of the light guide plate 101. The light incident surface and the light emitting surface of the light guide plate 101 are perpendicular to each other, that is, in the present embodiment, the backlight module 10 is a side-in type backlight module.

It should be understood that the light emitted by the blue light source 102 is blue light, and the blue light source 102 can be any light source capable of emitting blue light, such as a blue LED light source.

In this embodiment, the blue light emitted from the blue light source 102 enters from the light incident surface of the light guide plate 101, exits from the light exiting surface of the light guide plate 101, passes through the optical film 103, and enters the liquid crystal display panel 11, and an arrow inside the backlight module 10 in fig. 1 is a transmission direction of the blue light emitted from the blue light source 102 in the backlight module 10. That is, in fig. 1, the light incident surface of the light guide plate 101 is a side surface facing the blue light source 102, and the light emitting surface of the light guide plate 101 is a top surface of the light guide plate 101. Because the light that blue light source 102 sent is monochromatic light, when monochromatic light was transmitted in light guide plate 101, optics diaphragm 103, the loss is the same, can not exist because the different uneven circumstances of colour that leads to of the absorption loss of light guide plate 101, optics diaphragm 103 to the light of different colours, consequently, the blue light that blue light source 102 sent is behind light guide plate 101 and optics diaphragm 103, and the light colour that shoots into liquid crystal display panel 11 is even, has promoted LCD's optical effect.

In this embodiment, the optical film 103 may be a transparent film, or the optical film 103 may be a film capable of improving an optical effect, for example, a brightness enhancement film, a diffusion film, or the like.

In this embodiment, the liquid crystal display panel 11 includes: a first transparent substrate layer 111, a semiconductor element layer 112, a liquid crystal layer 113, a pixel layer 114, and a second transparent substrate layer 115, which are sequentially disposed along a light emitting direction of the backlight module 10 (i.e., a direction indicated by an arrow between the backlight module 10 and the liquid crystal display panel 11 in fig. 1). That is, the light emitted from the backlight module 10 enters the liquid crystal display panel 11, passes through the first transparent substrate layer 111, the semiconductor element layer 112, the liquid crystal layer 113, the pixel layer 114, and the second transparent substrate layer 115 in this order, and then exits the liquid crystal display panel 11.

In this embodiment, the first transparent substrate layer 111 is disposed on the light exit side of the optical film 103; the first transparent substrate layer 111 includes: a first transparent substrate 1112, and a yellow phosphor optical film 1111 disposed inside the first transparent substrate 1112.

The first transparent substrate 1112 is made of a transparent material, which may be Glass, PET (thermoplastic polyester), PI (Polyimide), or the like.

After passing through the light guide plate 101 and the optical film 103, the blue light emitted from the blue light source 102 firstly enters the yellow phosphor optical film 1111 included in the first transparent substrate layer 111 of the liquid crystal display panel 11, so as to excite the yellow phosphor to become white light, and then the white light sequentially enters the semiconductor element layer 112, the liquid crystal layer 113, the pixel layer 114 and the second transparent substrate layer 115.

In one example, referring to fig. 2-1, the thickness of the yellow phosphor optical film 1111 may be less than the thickness of the first transparent substrate 1112, and optionally, the yellow phosphor optical film 1111 may be in the form of a thin film, such as a yellow phosphor optical film.

In one example, referring to fig. 2-2, the thickness of yellow phosphor optical film 1111 may be equal to the thickness of first transparent substrate 1112.

In this embodiment, the semiconductor element layer 112 is provided between the first transparent substrate layer 111 and the liquid crystal layer 113 for driving the liquid crystal display.

In this embodiment, the liquid crystal layer 113 is disposed between the semiconductor element layer 112 and the pixel layer 114, and is used to provide a change in the alignment state of liquid crystal molecules by applying an external electric field, thereby causing a change in the optical characteristics of the liquid crystal cell.

In one example, referring to fig. 3-1, the thickness of each portion of the liquid crystal layer 113 is set to be non-uniform; the thicknesses of different parts of the liquid crystal layer 113 are matched with the thicknesses of different parts of the pixel layer 114, the pixel layer 114 comprises a plurality of blue light resistors, red light resistors and green light resistors which are sequentially arranged, the thicknesses of different light resistors are different, the thickness of the blue light resistors is the largest, the thickness of the green light resistors is the second largest, the thickness of the red light resistors is the smallest, correspondingly, the thickness of the liquid crystal layer at the position corresponding to the blue light resistors is the smallest, the thickness of the liquid crystal layer at the position corresponding to the green light resistors is the second largest, and the thickness of the liquid crystal layer at the position corresponding to the red light resistors is the largest. Since the light incident on the liquid crystal layer 113 is white, the liquid crystal layer 113 having a non-uniform thickness at different portions is provided, thereby preventing the difference in refractive index of the liquid crystal layer 113 with respect to light having different wavelengths.

In one example, referring to fig. 3-2, the thickness of each portion of the liquid crystal layer 113 is set to be uniform; the pixel layer 114 includes a plurality of sequentially arranged blue photoresist, red photoresist, and green photoresist, and the thicknesses of different photoresist portions are the same, and correspondingly, the thicknesses of the liquid crystal layers at the corresponding positions of the different photoresist portions are the same. Thus, although the difference caused by the different refractive indexes of the light with different wavelengths is not considered, the manufacturing difficulty of the liquid crystal layer 113 is low, bubbles are not easy to generate, the light leakage phenomenon can be avoided, and the optical effect of the liquid crystal display is improved.

In this embodiment, the pixel layer 114 includes: a plurality of blue sub-pixel units 1143, red sub-pixel units 1142, and green sub-pixel units 1141 arranged in sequence. The light emitted from the blue sub-pixel unit 1143 is blue light, the light emitted from the red sub-pixel unit 1142 is red light, and the light emitted from the green sub-pixel unit 1141 is green light, so as to form a desired color on the display surface of the liquid crystal display. The arrangement modes of the blue sub-pixel unit 1143, the red sub-pixel unit 1142 and the green sub-pixel unit 1141 can be flexibly set according to actual needs; for example, the blue sub-pixel unit 1143, the red sub-pixel unit 1142, and the green sub-pixel unit 1141 may be arranged at intervals.

In one example, the blue sub-pixel unit, the red sub-pixel unit and the green sub-pixel unit are arranged at intervals in the order of the blue sub-pixel unit, the red sub-pixel unit and the green sub-pixel unit in the transverse direction.

In one example, the red sub-pixel unit, the blue sub-pixel unit and the green sub-pixel unit are arranged at intervals in the order of the red sub-pixel unit, the blue sub-pixel unit and the green sub-pixel unit in the transverse direction.

In one example, the green sub-pixel unit, the red sub-pixel unit and the blue sub-pixel unit are arranged at intervals in the order of the green sub-pixel unit, the red sub-pixel unit and the blue sub-pixel unit in the transverse direction.

It should be noted that, in order to make the light emitted from the red sub-pixel unit 1142 be red light and the light emitted from the green sub-pixel unit 1141 be green light, in this embodiment, the red sub-pixel unit 1142 includes a red photoresist and the green sub-pixel unit 1141 includes a green photoresist.

In one example, to make the light emitted from the blue sub-pixel unit 1143 blue, referring to fig. 4-1 and 4-2, the blue sub-pixel unit 1143 includes a blue photoresist; the yellow phosphor optical film 1111 is completely covered with yellow phosphor, wherein the position of the yellow phosphor optical film partially covered with the yellow phosphor corresponds to the positions of the blue sub-pixel unit 1143, the red sub-pixel unit 1142 and the green sub-pixel unit 1141; 4-1, 4-2 because the thickness of the yellow phosphor optical film 1111 is equal to the thickness of the first transparent substrate 1112, the two are completely overlapped; that is, the yellow phosphor optical film 1111 is disposed on the first transparent substrate layer 111 at positions corresponding to the blue sub-pixel unit 1143, the red sub-pixel unit 1142, and the green sub-pixel unit 1141. Thus, the blue light emitted by the blue light source 102 sequentially passes through the light guide plate 101 and the optical film 103, and is firstly emitted onto the yellow phosphor optical film 1111 of the first transparent substrate layer 111, and under the excitation of the yellow phosphor optical film 1111, white light is emitted, and the white light is respectively emitted into the blue sub-pixel unit 1143, the red sub-pixel unit 1142 and the green sub-pixel unit 1141, and is filtered by the blue light resistor to emit blue light, and is filtered by the red light resistor to emit red light, and is filtered by the green light resistor to emit green light; that is, the light incident on the blue sub-pixel unit 1143 is white light, and the light exiting the blue sub-pixel unit 1143 is blue light. In this way, blue light can be emitted from the blue sub-pixel unit, and the difficulty in manufacturing the yellow phosphor optical film 1111 can be reduced.

In one example, in order to make the light emitted from the blue sub-pixel unit be blue, referring to fig. 3-1 and 3-2, the yellow phosphor optical film 1111 is partially covered with yellow phosphor, where the yellow phosphor optical film is partially covered with yellow phosphor at a position corresponding to the positions of the red sub-pixel unit 1142 and the green sub-pixel unit 1141; in fig. 3-1 and 3-2, the thickness of the yellow phosphor optical film 1111 is equal to the thickness of the first transparent substrate 1112, and therefore, the two films are partially overlapped; that is, a yellow phosphor optical film 1111 is disposed at a position corresponding to the red subpixel unit 1142 and the green subpixel unit 1141 on the first transparent substrate layer 111, and the yellow phosphor optical film 1111 is not disposed at a position corresponding to the blue subpixel unit 1143 on the first transparent substrate layer 111. In this way, the blue light emitted from the blue light source 102 directly enters the blue sub-pixel unit 1143 after sequentially passing through the light guide plate 101, the optical film 103, the first transparent substrate layer 111, the semiconductor element layer 112, and the liquid crystal layer 113; that is, the light incident on the blue sub-pixel unit 1143 is blue light. In order to make the light emitted from the blue sub-pixel unit 1143 be blue light, the blue sub-pixel unit 1143 may include a blue photoresist, or the blue sub-pixel unit 1143 may also include a transparent photoresist, or the blue sub-pixel unit 1143 may also include both a blue photoresist and a transparent photoresist. In this way, the photoresist of the blue sub-pixel unit can be flexibly adjusted, and the flexibility is higher.

In this embodiment, the second transparent substrate layer 115 is disposed on the light exit side of the pixel layer 114; the second transparent substrate layer 115 includes: a second transparent substrate (not shown).

The transparent substrate is made of a transparent material, which may be Glass, PET (Polyethylene terephthalate), PI (Polyimide), or the like.
