Summary of the invention
Given this, be necessary that providing a kind of can realize the brightness enhancement film of wide viewing angle display effect and use the liquid crystal indicator of this brightness enhancement film.
A kind of brightness enhancement film, it is for modulating light.Described brightness enhancement film comprises a main part and is arranged on the optical modulation structure on described main part, and described optical modulation structure comprises self-assembled monolayer film.
A kind of liquid crystal indicator, comprises the display panels stacking 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 there is provided a kind of brightness enhancement film, can be compensated, can produce the spotlight effect of gradual change type, and provide a kind of liquid crystal indicator of wide viewing angle to specific direction light.

Embodiment
Embodiment one:
As shown in Figure 1, the liquid crystal indicator 1 of the specific embodiment of the invention comprises display panels 10, light control device 20 stacked gradually from top to bottom, and a backlight module 30.Described light control device 20 comprises a brightness enhancement film 22 and is separately positioned on the upper diffusion sheet 21 of brightness enhancement film 22 both sides and lower diffusion sheet 23.Be understandable that, other light control elements can also be comprised in described light control device 20 as lens etc.The optical modulation structure 224 that described brightness enhancement film 22 comprises a main part 222 and is arranged on described main part 222.Described backlight module 30 provides an area source, thinks that described display panels 10 provides backlight.
Described display panels 10 carrys out twisted liquid crystal molecule to control transmittance thus display image by applying voltage.As shown in Figure 2, described display panels 10 comprises the first high side 14 of transmittance and low the second side 15 of transmittance, and the transmittance of described display panels 10 is reduced to described second side 15 gradually by described first side 14.In the present embodiment, described first side 14 is display panels 10 top vertically, and described second side 15 is display panels 10 bottom vertically.
Described optical modulation structure 224 comprises self-assembled monolayer (Self-assembledmonolayers, SAMs) film.SAMs molecular jet is formed by the mode that described SAMs film sprays (Ink-Jet) by ink on described main part 222.Originally the light dispersed to all directions can be concentrated in the scope of certain angle by described SAMs molecule after by optical modulation structure 224.Therefore, the position spotlight effect high in SAMs molecular density is more obvious, and the brightness through 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 5*5 nanometer, and the lattice size of described thionaphthol SAMs molecule 224b is 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 lower than the arrangement density 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 near display panels 10 on described main part 222 is purified petroleum benzin thiophenol SAMs molecule 224a, and in described optical modulation structure 224, the ratio of benzenethiol SAMs molecule 224a and thionaphthol SAMs molecule 224b is reduced the SAMs molecular arrangement density of optical modulation structure 224 is increased to the second side 15 gradually by described first side 14 to the second side 15 by described first side 14 gradually.
So, arrange corresponding for the first higher with display panels 10 transmittance for part lower for brightness enhancement film 22 glazing modulated structure 224 density side 14, and arrange corresponding for the second lower with display panels 10 transmittance for part higher for brightness enhancement film 22 glazing modulated structure 224 density side 15, then can compensate cause occur brightness disproportionation phenomenon viewed from different visual angles by display panels 10 different parts transmittance difference originally, thus reach the effect of wide viewing angle.
In other embodiments, described SAMs molecule includes but not limited to that lattice size is the ethyl group dithiol SAMs molecule of 8*8nm or 4*4nm, lattice size is 5*5nm m-fluorine phenol SAMs molecule and lattice size are the p-nitre phenol SAMs molecular combinations of 10*10nm or 6*6nm, and optical modulation structure 224 also can be formed by above-mentioned multiple SAMs molecular mixing.As long as meet embodiment that SAMs molecular arrangement density increases to the second side 15 that transmittance is lower gradually by the first side 14 that transmittance is higher all within protection scope of the present invention.
Those skilled in the art will be appreciated that; above embodiment is only used to the present invention is described; and be not used as limitation of the invention; as long as within spirit of the present invention, the suitable change do above embodiment and change all drop within the scope of protection of present invention.
