Description
Technical field
The utility model relates to technical field of liquid crystal display more particularly to a kind of polarizers and liquid crystal display device.
Background technique
With the fast development of electronics technology and display technology, liquid crystal display (Liquid Crystal Display,
LCD it) is widely used, such as: LCD TV, smart phone, computer, tablet computer modernize on information equipment.
Liquid crystal display device on existing market is largely backlight liquid crystal display device comprising liquid crystal display panel and backlight mould
Group (Back Light Unit, abbreviation BLU).
Liquid crystal display panel is usually by color film (Color Filter, an abbreviation CF) substrate, a thin film transistor (TFT) (Thin
Film Transistor, abbreviation TFT) array substrate and one it is configured at liquid crystal layer (Liquid Crystal between two substrates
Layer, abbreviation LCL) it is constituted.CF substrate attaches a polarizer far from the side of liquid crystal layer, and tft array substrate is far from liquid crystal layer
Side also attach a polarizer.Liquid crystal display panel is controlled by orientation of the electric field to liquid crystal molecule, changes the inclined of light
Vibration state, and penetrating and stopping for optical path is realized by polaroid, achieve the purpose that display.Backlight module is usually with light-emitting diodes
It manages (Light Emitting Diode, abbreviation LED) and is used as backlight.
Blue light is largely present in the light such as computer display screen, fluorescent lamp, smart phone screen, digital product display screen, LED light
In, blue light refers to that wavelength is the high energy light of 380~480nm, and wavelength is short, energy is high.Particularly, wavelength is less than in 455nm
Low band blue light the macular area toxin amount in eyes can be made to increase, seriously threaten the eye health of people.It is blue in daily life
Light is seen everywhere, but the harmful blue light main source that people touch is LED liquid crystal display device.
Liquid crystal display device on existing market is generally used LED as backlight.Since backlight needs white light
Effect, so industry forms white light using blue led mixing yellow fluorescent powder.Since blue led is a main body hardware, because
The problem of blue color spectrum in this this white light just possesses a wave crest, hurts eye so as to form the harmful blue light described in us.
TV, or even many common people's meetings are seen in the main carriers that LED liquid crystal television is entertained as parlor, most of family's selection before sleeping at night
Light is shut when seeing TV, the factors such as splashette, cause harmful blue light to damage eyes in addition.Long-term accumulation causes eyes
Tired, dry and astringent, visual impairment, while it being also easy to excitation brown pigment, so that skin is grown macula lutea, freckle.Due to harmful blue light pair
The injury of eyes is accumulated over a long period, therefore TV blue light will cause enough attention, especially teenager to the injury of eyes
Children.
Low band blue light eyeshield mode more commonly used at present is roughly divided into following a few classes:
By adding membrane material to reduce the transmission of blue light outside display device surface, i.e., on the market commonly first way is
Anti-blue light eyeshield protective film plays the role of blue light blocking by being attached to outside display device.But which higher cost, it needs
It is voluntarily bought by consumer；Which can make picture taste be deteriorated simultaneously, i.e., picture product are yellow；In addition which can reduce display
Brightness.
The second way is adjusted by cell phone software, i.e., by adjusting backlight LED luminous efficiency, it is whole to reduce blue light
Brightness, and then the low band blue light brightness that wavelength is less than 455nm is reduced, this is also used anti-blue light eyeshield on current mobile phone
Mode.Which does not need to increase extra cost relative to first way；But low band blue light of the wavelength less than 455nm
Effect is rejected to be not obvious；It still there is picture taste Huang partially simultaneously.
Therefore, it is less than the low band blue light of 455nm in the prevalence of wavelength for current liquid crystal display device, it can be to making
User's eye causes irreversible injury, is especially particularly acute to the eye damage of youngsters and children, and is currently mainly used
The generally existing picture taste distortion of low band blue light eyeshield mode the problem of, how to reduce harmful blue light, shown without influencing
Taste, is urgent problem to be solved in LCD technology development process.
Utility model content
The purpose of the utility model is to provide a kind of polarizer and liquid crystal display devices, fill for current liquid crystal display
The low band blue light for being less than 455nm in the prevalence of wavelength is set, irreversible injury can be caused to user's eye, especially
The generally existing picture of low band blue light eyeshield mode that the eye damage of youngsters and children is particularly acute, and is currently mainly used
The problem of taste distortion, guarantees display taste, avoids the problem that display distortion while harmful blue light can be effectively reduced.
To achieve the above object, the utility model provides a kind of polarizer, and the polarizer includes: polarizing layer；Low wave
Section blue Light Film, is arranged in the upside or downside of the polarizing layer, wherein defining blue light of the wavelength less than 455nm is that low band is blue
Light；Release film, is arranged in the downside of the polarizing layer, and the release film passes through adhesion coating and the polarizing layer or the low band
Blue Light Film connection；And protective film, the upside of the polarizing layer is set.
To achieve the above object, the utility model additionally provides a kind of liquid crystal display device, the liquid crystal display device packet
Liquid crystal display panel and backlight module are included, the liquid crystal display panel includes array substrate, color membrane substrates and is arranged described
The separate liquid of the array substrate is arranged in liquid crystal layer between array substrate and the color membrane substrates, the backlight module
The side of crystal layer；The liquid crystal display device further include: the separate liquid crystal of the color membrane substrates is arranged in the first polarizer
The side of layer；And second polarizer, it is arranged between the array substrate and the backlight module；Wherein, described first partially
At least one of tabula rasa and second polarizer use polarizer described in the utility model.
Utility model has the advantages that, by being adjusted to polarisation type structure, making on the basis of not increasing membrane material
Supporting layer is substituted with low band blue Light Film, plays to damaging wavelengths blue light filter effect, to reduce blue light injury, can reduce about
50% harmful blue light realizes anti-low band blue light eyeshield effect.Relative to the anti-blue light glass of outer patch, the utility model polarisation
While low band blue light ratio in blue light is effectively reduced in plate, the influence to polarizer integral thickness can be effectively reduced, and right
The transmission of other band of light has no significant effect, and penetrance is avoided to reduce, and can largely guarantee display taste, avoid showing
The problem of distortion.Meanwhile compared to existing most low band blue light products, the utility model polarizer can be controlled into effectively
This, has stronger usability, is conducive to promote.
