Description
Technical field
The utility model relates to a kind of colored filter, is specifically related to a kind of semi-transmission type colored spectral filter.
Background technology
LCD (Liquid Crystal Display, be called for short LCD) itself can not be luminous, needing could be luminous by other light source (being bias light), and colored filter (Color Filter is called for short CF) is to realize the colored vitals that shows in the LCD.That existing LCD colored filter is divided into substantially is reflective, transmission-type, semi-transparently cross semi-reflective (being semi-transmission-type) three kinds.Wherein, semi-transmission type colored spectral filter has unique advantage, often is applied on the liquid crystal color screen of mobile product such as mobile phone.Under dim indoor environment, the white light of backlight obtains the bright colored image after seeing through colored filter; Under bright outdoor environment, sunshine is injected colored filter and is obtained bright coloured image through the reflectance coating reflection.
At present, the version that generally adopts of semi-transmission type colored spectral filter is the reflectance coating open-type.Adopt this version can obtain preferable outdoor looking property and the reflecting effect distinguished, can use in bright or dim place, but its illuminating ray is to utilize outside fluorescent light or the sunshine of reflectance coating reflection, seeing through polaroid and colored filter again forms through birefringence, therefore, overall light can be bigger than the loss of transmission-type colored filter, causes the display brightness of LCD darker than transmission-type.
The utility model content
Technical problem to be solved in the utility model is at semi-transmission type colored spectral filter above shortcomings in the prior art, and a kind of colored filter that can effectively improve the reflectivity of color filter film is provided.
The technical scheme that solution the utility model technical matters is adopted is that this colored filter comprises transparency carrier, BM photomask, reflectance coating and the colour filter film, insulating protective film and the nesa coating that set gradually from backlight toward outside light source direction on transparency carrier; described BM photomask is arranged on the transparency carrier; the part that is not covered by the BM photomask on the transparency carrier forms opening; also be provided with the inclined-plane in the described opening; form a pitch angle between described inclined-plane and the transparency carrier, described reflectance coating covers on the described inclined-plane.Because part or all of reflecting surface and the transparency carrier of reflectance coating are obliquely installed, thereby can make light from this optical filter both sides incident whole or major part after the reflectance coating reflection can both enter in people's the angular field of view.
A kind of scheme is, described inclined-plane is formed by BM photomask any one side adjacent with opening or the part of described any one side, and described reflectance coating covers on the described inclined-plane, and described colour filter film is located on opening and the reflectance coating.
Preferably, the inclined-plane of BM photomask and the pitch angle of transparency carrier are 30 °～45 °, more preferably 45 °.
Another kind of scheme is, described reflectance coating is arranged in the opening, makes reflectance coating and BM photomask be disposed on the transparency carrier, and described inclined-plane is formed by the part or all of reflecting surface of reflectance coating, and described colour filter film is located on opening and the reflectance coating.
Preferably, the cross sectional shape of described reflectance coating is right-angle triangle or right-angled trapezium.
Further preferably, a right-angle side of described right-angle triangle or the base of described right-angled trapezium and transparency carrier are fitted, and another right-angle side of right-angle triangle or the right-angle side of right-angled trapezium and BM photomask are fitted.
Preferably, the hypotenuse of described right-angle triangle or right-angled trapezium and the pitch angle between the transparency carrier are 30 °～45 °, more preferably 45 °.
Certainly, the cross sectional shape of reflectance coating also can adopt other shape, as long as can make the part or all of reflecting surface and the transparency carrier of reflectance coating be obliquely installed.
Preferably, the thickness of the reflectance coating that is provided with on the transparency carrier is not more than the thickness of BM photomask, to improve the flatness of whole optical filter.
Preferably, the thickness of described BM photomask is 0.5～2.0 micron, and the thickness of described reflectance coating is 0.15～0.5 micron.
The cross sectional shape major part of reflectance coating of the prior art is a rectangle, that is to say, the reflecting surface of reflectance coating is parallel with transparency carrier, thereby light that can not usable reflection optical filter both sides, still reflect away from its both sides after the reflectance coating reflection from the light of optical filter both sides incident, the utilization factor of light is low.And the reflecting surface of the reflectance coating in the utility model is the inclined-plane, the light of optical filter both sides can make limited light concentrate and accumulate in the field of view of human eye after the reflectance coating reflection, thereby the brightness of display is promoted, effectively improve the utilization factor of light, improved the reflectivity of colored filter.
In addition, owing on the BM photomask, do not set up one deck reflectance coating, thereby the light that they not only can usable reflection colored filter both sides, and reduced the thickness of colored filter.
