Abstract

A kind of TFT screen construction and the sootiness membrane structure for TFT screen, polarized light piece is provided on the screen ontology of TFT screen, sootiness film is covered on polarized light piece, sootiness film includes the transparent substrate being covered on TFT screen, and PVA layers are provided in polarized light piece and transparent substrate.The light that TFT screen issues shows pattern and color effects by polaroid, and the PVA layer on sootiness film has lower absorptivity to the polarised light that TFT screen issues, but for ambient light, that is non-polarized light absorptivity with higher, to significantly reduce ambient light to the influence degree of TFT Showing Effectiveness On Screen, load needed for TFT screen work can be effectively reduced, and it can guarantee the job stability and service life of TFT screen, while also favorably improving putting out for screen and shielding the black effect of one.

Description

A kind of TFT screen construction and the sootiness membrane structure for TFT screen
Technical field
The present invention relates to TFT screen and the optical diaphragms on TFT screen, more particularly to a kind of TFT screen construction And the sootiness membrane structure for TFT screen.
Background technique
TFT(Thin Film Transistor) screen is thin film transistor, and sootiness film is then a kind of pair of light Light transmission diaphragm with certain absorbability.Sootiness film is usually used in auto lamp, on TFT screen or other needs to hide user The scene of product surface details.Such as among the use of TFT screen, sootiness film can be formed when screen is closed " puts out screen one It is black " visual effect so that screen extinguish when color and non-display area it is as consistent as possible, to improve aesthetics.
About 50% or so light can be absorbed currently used for the sootiness film on TFT screen, but since it is to polarised light (example Such as TFT backlight) absorption and be to the absorption of non-polarized light (natural environment light) it is equivalent, cause it that can not only absorb exterior light Line, equally can also absorb the light of TFT screen sending, and the backlighting capability so as to cause TFT screen is weakened.In this situation Under, in order to guarantee the display effect of TFT screen, it is necessary to increase the backlight power of TFT screen to compensate, but this is also increased The load and energy consumption of light source, while can also reduce the service life of TFT screen.
Summary of the invention
It is higher than the TFT screen construction of non-polarized light the purpose of the present invention is to provide a kind of polarization light transmittance and is used for The sootiness membrane structure of TFT screen, load needed for reducing TFT screen work while to guarantee TFT Showing Effectiveness On Screen.
Sootiness membrane structure of the present invention for TFT screen, it is transparent including the transparent substrate being covered on TFT screen Substrate is the diaphragm that high light transmission material is made, and PVA layers are covered on the inside of transparent substrate.
TFT screen construction of the present invention, including screen ontology and the polarized light piece being set on screen ontology, partially Transparent substrate is covered on vibration mating plate, transparent substrate is the diaphragm that high light transmission material is made, and is covered on the inside of transparent substrate It is stamped PVA layers.
TFT screen construction of the present invention and sootiness membrane structure for TFT screen, on the screen ontology of TFT screen It is provided with polarized light piece, has been provided with PVA(polyvinyl alcohol, polyvinyl alcohol in the polarized light piece in itself) layer, TFT The light that screen issues shows pattern and color effects by polaroid;Meanwhile it is provided with again on polarized light piece with another PVA layers of sootiness film, this makes the distance between two PVA layers to be very close to;In the case, the light that TFT screen issues (polarised light) is extremely consistent with the light-transmission angles of sootiness film in the angle after polarized light piece, so that the light that TFT screen issues Line percent of pass with higher, so, the PVA layer on sootiness film has lower absorptivity to the light that TFT screen issues;And For ambient light (non-polarized light), PVA layer on sootiness film to its barrier absorption with higher, TFT screen not The non-polarized light that 50% or more outside is injected can be obstructed and absorbed when luminous, to form higher absorptivity.TFT screen as a result, TFT screen exit rays are had lower absorption by the outer sootiness film being arranged of curtain, but are had again to ambient light simultaneously high Absorption can be effectively reduced to significantly reduce ambient light to the influence degree of TFT Showing Effectiveness On Screen Load needed for TFT screen work, and can guarantee the job stability and service life of TFT screen, while also advantageous improve is shielded Curtain puts out the black effect of screen one.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the sootiness membrane structure for TFT screen.
Fig. 2 is the structural schematic diagram of TFT screen construction.
Specific embodiment
A kind of sootiness membrane structure for TFT screen, including the transparent substrate 3 being covered on TFT screen, transparent substrate is height The diaphragm that translucent material is made, and PVA layer 4 is covered on the inside of transparent substrate.
A kind of TFT screen construction, including screen ontology 1 and the polarized light piece being set on screen ontology 2, polarized light piece On be covered with transparent substrate 3, transparent substrate is the diaphragm that high light transmission material is made, and is covered on the inside of transparent substrate PVA layer 4.
It is the structural schematic diagram of the sootiness membrane structure of the present invention for TFT screen as shown in Figure 1, the PVA on sootiness film Layer is set to the inside of transparent substrate;Fig. 2 is the structural schematic diagram for having used the TFT screen construction of sootiness membrane structure.TFT screen It is provided with polarized light piece on TFT screen ontology in structure, has been provided with PVA(polyvinyl in itself in the polarized light piece Alcohol, polyvinyl alcohol) layer, the light that TFT screen issues shows pattern and color effects by polaroid;Meanwhile it polarizing The sootiness film with another PVA layers is provided on mating plate again, this makes the distance between two PVA layers to be very close to;In this feelings Under condition, the light (polarised light) that TFT screen issues is in the angle and the light-transmission angles extremely one of sootiness film after polarized light piece It causes, so that the light percent of pass with higher that TFT screen issues, so, what the PVA layer on sootiness film issued TFT screen Light has lower absorptivity;And for ambient light (non-polarized light), the PVA layer on sootiness film is to its resistance with higher Every absorption, the non-polarized light that 50% or more outside is injected can be obstructed and absorbed when TFT screen does not shine, to be formed Higher absorptivity.The sootiness film being arranged outside TFT screen as a result, has lower absorption to TFT screen exit rays, but There is high absorption to ambient light again simultaneously, to significantly reduce ambient light to TFT Showing Effectiveness On Screen Influence degree.
The sootiness membrane structure for TFT screen, transparent substrate 3 be single or multi-layer structure, each layer structure respectively by PC(Polycarbonate, polycarbonate), PMMA(poly (methyl methacrylate), polymethyl methacrylate), TAC(Triacetyl Cellulose, Triafol T), PET(Polyethylene terephthalate, gather to benzene two Formic acid glycol ester), any material in glass is made.
The thickness of the sootiness membrane structure for TFT screen, sootiness film is not less than 0.50mm, especially with 0.5-1.0mm's With a thickness of best.This is because if the thickness of sootiness film is too small, characteristic will correspondingly become excessively soft, thus improve by It is pasted onto the operation difficulty on TFT screen, pastes required glue also necessary purity with higher, and then improve work Difficulty and processing cost.The thickness of sootiness film is held between 0.5-1.0mm as a result, can be kept away while guaranteeing hardness Exempt from diaphragm it is blocked up caused by light losing, also reduce the installation difficulty and installation cost of sootiness film.
