Description
Technical field
The present invention relates to optical technology, be specifically related to a kind of projection screen, and preparation method thereof and control the method for light with this projection screen.
Background technology
Projection screen is used in film, office, home theater, in convention occasion.Be used for show image, video file instrument.Projection screen generally can be divided into reflective, transmission-type two class; Reflective for just throwing, transmission-type is used for rear-projection; Just throw curtain and be divided into again plane curtain, camber curtain; Plane curtain can be divided into glass bead screen, metal curtain, embossing plastics curtain, elasticity curtain etc. (embossing plastics be divided into whitely to mould, ash is moulded, silver moulds) quality.
Screen gain skill technology; Gain: be expect intrinsic reflection characteristic (light levels of all angles) with numeral curtain.To the light that complete diffuse scattering surface (namely 180 degree of directional reflectance ratios are all the same reflectings surface up and down) upper projection is certain, reflecting brightness is at this moment set as 1.Then under identical conditions, the direction to screen vertical projects same light, measures the brightness of each point on central point and same circular arc, and the ratio of the brightness of this brightness and complete diffuse scattering is just named the gain of screen.
Screen gain is on the impact of image: the comparatively gentle loyalty of the image not having the screen of gain to present, but is easily subject to the impact of environment and extraneous light.Have the screen of gain then to bring bright, levels are rich, bright picture, and environment and extraneous light less on its impact.But the viewing angle of the gain of screen and screen has special inverse relation, and namely gain is higher, observation visual angle will be less.
Mould curtain in vain: refer to the curtain that surface is coated with adularescent special material.This curtain spectators seem that color matter is bright-coloured.Feature is low price, and visible angle is large, and the scope of application is the widest, the main Types curtain that the sales promotion of Ye Shi businessman is sent.But gain is 1, to picture brightness promote and not obvious.
Metal curtain: be a kind of hard curtain, be characterized in that planarization is good, not fragile, long service life, gain is large, and picture brightness is high, and gain can reach 3 to 5 and the gain of general white wall is 1 usually.But metal curtain shortcoming expensively moulds expensive tens times of curtain than common white, and contrast is lower.Be mainly used in the large-scale exhibition room of working environment and meeting-place.
Glass bead screen: refer to surface adhesive have the curtain of superfine glass pearl.This beaded glass is thin and even, and spectators seem that brightness high stereoscopic sensation is strong, and color matter is bright-coloured.Feature is that brightness is high, and gain is generally 2 to 4, but visible angle is little, and when the spectators on side watch, effect is not so good.Moderate cost, is relatively applicable to space less, requires that the user of high brightness selects.
Existing curtain is various in style, and some curtain has done gain process, by reducing visual range, add screen intensity, but the interference under ambient light of these curtains is exerted oneself, and contrast obviously reduces under the interference of visible light inadequate, and gray scale increases.Have impact on visual effect.Surround lighting refers to ambient light, and be generally the open air on daytime, daytime opens window, or light etc. of turning on light when projecting, so existing curtain is all use in dark conditions, and can not use having the daylight environment of light.
Mould curtain in vain: moulding that curtain uses under environment by day is in vain the bald-faced the wounded, at the obvious gray of the dark colored portion of shooting sub-screen to death of surround lighting, image can lose original contrast, image fault, moulding curtain is in vain unrestrained anti-view principle, its visual range extensively arbitrarily angledly can be seen to 180 degree, but also can suffer that the invasion of 180 degree of arbitrarily angled surround lightings makes and image loses original image quality.So the defect of moulding curtain in vain is least suitably in daytime or uses under being with the condition of surround lighting.
Metal curtain: metal curtain is smooth glossy, reflective is good, there is certain gain effect, improve the brightness effects of picture, but use under ambient light, equally also can be subject to the interference of surround lighting, stray light is directly proportional under gain, and the gain of metal curtain under projected light is how many, and the obstacle gain of surround lighting also can be how many, gain just improves the brightness of picture, and can not stop the interference of surround lighting.
Glass bead screen: glass bead screen is typical regression screen, because light reflection can go back by the beaded glass on curtain face centered by the incident direction of projected light, so just can see bright bright-coloured image in usual audiovisual position.Owing to inhibit the diffuse scattering of screen to a certain extent, the image seen near screen front can be different with the brightness of the image seen on the position that angle is larger.Near screen front, can see brightness, contrast, level is image all well.But good image quality is not seen in the side of screen.
Having extraneous light, under the environment of mixed and disorderly light, because screen is along extraneous light, the incident direction of mixed and disorderly light is reflected back, so the image light of projector and extraneous light, mixed and disorderly light is seldom overlapping, thus can obtain bright-coloured image.But screen is seen in the position standing in extraneous light, it is seen that the light that your luminous position reflects, and do not see the picture launched in projector direction, so glass bead screen effectively can not stop the interference of surround lighting.
From existing curtain, projection screen is all use in dark conditions.And can not use having the daytime of ambient light interference.Thus projector's service condition is limited to very much.
