Technical field
The present invention relates to a kind of brightness enhancement film and use the liquid crystal indicator of this brightness enhancement film.
Background technology
Thereby liquid crystal display is controlled transmittance demonstration information by the rotation of liquid crystal molecule, and existing modal TN type liquid crystal technology is the most ripe, and the scope of application is the widest, but there is visible angle deficiency less than normal in it.Because TN type liquid crystal reverses, general TN type liquid crystal display when watching screen from the screen top, is easily seen the major axis of liquid crystal molecule after applying voltage, and light transmission capacity is large, and screen can be crossed bright and turn white, and contrast is low; When watching screen from the screen below, easily see the minor axis of liquid crystal molecule, light transmission capacity is little, and screen can be excessively dark, causes transmittance uneven, and display effect is not good.Common method is to stick one deck optical compensation films outside screen panel, and visible angle is increased, but needs to add extra cost.
For improving the problem of TN type liquid crystal visible angle deficiency, people begin to make an issue of on the brightness enhancement film of backlight assembly.In patent CN200410095781, disclosed a kind of backlight assembly of liquid crystal display, wherein brightness enhancement film is prismatic lens, comprise a plurality of optical modulation structures, each is shaped as the form of scalene triangle prism, each is given prominence to has two base angles of not waiting each other, with the adjustable liquid crystal display display viewing angles.But can cause light transmission capacity uncontrollable with the scalene triangle prism design, can't do compensation for relatively poor zone, TN type liquid crystal visual angle, and its photoconduction is to only past same direction, so can cause other visual angle irregular colour, the luminance contrast ratio of panel is declined to a great extent, and found by human eye.In patent CN200880000121, disclosed a kind of backlight assembly of liquid crystal display, wherein brightness enhancement film is prismatic lens, comprise be used to the first prism facets of injecting light and the second prism facets, the first prism facets is linearity, and the second prism facets is circular-arc, with adjustable visual angle, but its photoconduction is to only past same direction, so can cause other visual angle irregular colour, the luminance contrast ratio of panel is declined to a great extent, and found by human eye.
Summary of the invention
Given this, be necessary to provide a kind of liquid crystal indicator that can realize the brightness enhancement film of wide viewing angle display effect and use this brightness enhancement film.
A kind of brightness enhancement film, it is used for light is modulated.Described brightness enhancement film comprises a main part and is arranged on optical modulation structure on the described main part, and described optical modulation structure comprises self-assembled monolayer film.
A kind of liquid crystal indicator comprises a display panels that stacks gradually placement, a light control device, and a backlight module, and described light control device comprises described brightness enhancement film.
Advantage of the present invention has provided a kind of brightness enhancement film, can be compensated to specific direction light, can produce the spotlight effect of gradual change type, and the liquid crystal indicator that a kind of wide viewing angle is provided.

Embodiment
Embodiment one:
As shown in Figure 1, the liquid crystal indicator 1 of the specific embodiment of the invention comprises a display panels 10, one light control devices 20 that stack gradually from top to bottom, and a backlight module 30.Upper diffusion sheet 21 and lower diffusion sheet 23 that described light control device 20 comprises a brightness enhancement film 22 and is separately positioned on brightness enhancement film 22 both sides.Be understandable that, can also comprise other light control elements such as lens etc. in the described light control device 20.Described brightness enhancement film 22 comprises a main part 222 and is arranged on optical modulation structure 224 on the described main part 222.Described backlight module 30 provides an area source, thinks that described display panels 10 provides backlight.
Thereby described display panels 10 reverses liquid crystal molecule with control transmittance demonstration image by applying voltage.As shown in Figure 2, described display panels 10 comprises the first side 14 and the second low side 15 of transmittance that transmittance is high, and the transmittance of described display panels 10 is reduced gradually by described the first side 14 to described the second side 15.In the present embodiment, described the first side 14 is display panels 10 top vertically, and described the second side 15 is display panels 10 bottom vertically.
Described optical modulation structure 224 comprises self-assembled monolayer (Self-assembledmonolayers, SAMs) film.Described SAMs film sprays (Ink-Jet) by ink mode forms the SAMs molecular jet at described main part 222.Described SAMs molecule can be concentrated in the light of originally dispersing to all directions in the scope of certain angle after by optical modulation structure 224.Therefore, more obvious at the position spotlight effect that the SAMs molecular density is high, the brightness of passing light is higher.In the present embodiment, described SAMs molecule comprises benzenethiol SAMs molecule 224a and thionaphthol SAMs molecule 224b.The lattice size of described benzenethiol SAMs molecule 224a is the 5*5 nanometer, and the lattice size of described thionaphthol SAMs molecule 224b is the 2.5*2.5 nanometer.On the main part 222 of unit area, the arranging density of the benzenethiol SAMs molecule 224a that lattice is larger will be lower than the density of arranging of thionaphthol SAMs molecule 224b.So on the main part 222 of unit area, the ratio of benzenethiol SAMs molecule 224a and thionaphthol SAMs molecule 224b is larger, then the SAMs molecular density of described optical modulation structure 224 is less, and the light of deriving is also fewer.
As shown in Figure 3, the optical modulation structure 224 of the first side 14 of close display panels 10 is purified petroleum benzin thiophenol SAMs molecule 224a on the described main part 222, and the ratio of benzenethiol SAMs molecule 224a and thionaphthol SAMs molecule 224b is reduced so that the SAMs molecular arrangement density of optical modulation structure 224 is increased to the second side 15 gradually by described the first side 14 to the second side 15 gradually by described the first side 14 in the described optical modulation structure 224.
So, the first side 14 corresponding settings that the part that brightness enhancement film 22 glazing modulated structures 224 density are lower is higher with display panels 10 transmittances, and the part that brightness enhancement film 22 glazing modulated structures 224 density are the higher second side 15 corresponding settings lower with display panels 10 transmittances, the brightness disproportionation phenomenon appears in seeing from different visual angles of causing by display panels 10 different parts transmittances are different then can to compensate script, thereby reaches the effect of wide viewing angle.
In other embodiments, described SAMs molecule includes but not limited to that the lattice size is the meta-fluorine phenol SAMs molecule of 5*5nm and the big or small p-nitre phenol SAMs molecular combinations for 10*10nm or 6*6nm of lattice for ethyl group dithiol SAMs molecule, the lattice size of 8*8nm or 4*4nm, and optical modulation structure 224 also can be formed by above-mentioned multiple SAMs molecular mixing.As long as satisfy embodiment that SAMs molecular arrangement density increases to the second lower side 15 of transmittance gradually by higher the first side 14 of transmittance all within protection scope of the present invention.
Those skilled in the art will be appreciated that; above embodiment only is that the present invention is described; and be not to be used as limitation of the invention; as long as within connotation scope of the present invention, appropriate change and variation that above embodiment is done all drop within the scope of protection of present invention.
