Abstract
The related process equipment for column lens plate comprises a first embossing unit, and a second embossing unit and a printing unit on the first unit ends respectively to hold part substrate together and joint the first unit. It also provides the corresponding method.
Description
Technical field
The present invention relates to the manufacturing equipment and the method for a kind of manufacturing equipment and method, particularly a kind of column type lens plate.
Background technology
Rear projection screen is a characteristic with its giant-screen, clear picture, utilize the screen of iconoscope to compare with tradition, the advantages such as rear projection screen is radiationless except having, picture dimension is big, more can directly connect computing machine or other audio-visual devices, reach maximum entertainment effect.Therefore, along with the raising of standard of living and the improvement of living conditions, rear projection screen more and more is subjected to consumer's favor.
In recent years, the light engine technology of rear projection screen is little by little ripe, and because rear projection screen is projected to rear projection screen by projection arrangement with image, after passing through rear projection screen, enters beholder's eyes.So when the design rear projection screen, must consider beholder's visual angle, the problems such as contrast, resolution and brightness of image.
Please refer to Fig. 1, rear projection screen 1 is a penetrating type screen (Transmissive Screen), and it is mainly by 12 formations of a Fresnel lens plate (Fresnel Lens Sheet) 11 and one column type lens plate (Lenticular Lens Sheet).Wherein, the incident light that light source sent is injected Fresnel lens plate 11 optically focused earlier to form directional light, is incident upon column type lens plate 12 again.
As shown in Figure 2, existing column type lens plate 12 comprises: plural lens pillar 121, a transparency carrier 122, a light-sensitive surface 123 and a light shield layer 124.Wherein, plural lens pillar 121 is arranged at a side of transparency carrier 122, and light-sensitive surface 123 is arranged at the opposite side of transparency carrier 122, utilizes the stickiness of light-sensitive surface 123 partly light shield layer 124 can be sticked.Wherein, light shield layer 124 (can be described as the black-tape striped again, Black Stripe) is arranged at the non-extraction regions (Non-Focusing Area) of light-sensitive surface 123, and light shield layer 124 can reduce the influence of extraneous light and increase contrast in order to the absorbing light line.Come the distribution of light of controlling level direction by plural lens pillar 121 on the column type lens plate 12, promoting the luminance uniformity of image, and make the light in the ken can do good utilization.
Please refer to Fig. 3, the manufacture method of existing column type lens plate comprises: be coated with a photo-curable resin in a side (step S110), embossing and the photo-curable resin that hardens (step S120) of a transparency carrier, bind a light-sensitive surface in the opposite side (step S130) of transparency carrier and transfer printing one light shield layer in light-sensitive surface (step S140).
Then please also refer to Fig. 2 and Fig. 4, in order to make column type lens plate 12, in existing lens pillar panel manufacturing apparatus 20, is that transparency carrier 122 is sent to an apparatus for coating 21, so that photo-curable resin is coated on the transparency carrier 122.Then, behind the lines through impression cylinder 22, the plural lens pillar 121 of 22 ' (Embossing Roller) extrusion, promptly utilize the first UV-irradiation device 23 to be cured, so that lens pillar 121 setting.Then, utilize the first superimposed cylinder 24,24 ' (Laminating Roller) light-sensitive surface 123 is binded a side to transparency carrier 122.The light that the second UV-irradiation device 25 is launched, convergence ground shine the extraction regions (Focusing Area) in light-sensitive surface 123, and extraction regions is subjected to then not have after the illumination curing stickiness.Therefore when carrying out the transfer printing of light shield layer 124 by the second superimposed cylinder 26,26 ', the non-light collecting part that black carbon powder only can be had stickiness sticks, and promptly forms light shield layer 124 in the non-extraction regions of light-sensitive surface 123.Thus, promptly finish the making of column type lens plate 12.
Yet, in the manufacture method of existing lens pillar,, printing ink directly is printed on the non-extraction regions of lens pillar 121 if desire is utilized mode of printing, when forming light shield layer 124, need to overcome the problem of contraposition precision.Because the spacing distance between the non-extraction regions has only 50 μ m approximately, thus as long as contraposition is accurate inadequately, then can influence the luminous flux of whole column type lens plate 12, and then make the yield of lens pillar version 12 descend.Therefore, existing column type lens plate 12 is mostly abandoned the mode of printing, and is adopted the processing procedure that attaches light-sensitive surface 123 and exposure to form light shield layer 124 when forming light shield layer 124.Lose stickiness after utilizing the extraction regions exposure of light-sensitive surface 123, an only remaining non-extraction regions has stickiness to stick together carbon dust, to form contraposition light shield layer 124 accurately.This is for the manufacturer that produces column type lens plate 12, and not only higher, the speed of production of processing procedure cost complicated, manufacturing equipment reduces, and also improved production cost.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art and defective, a kind of manufacturing equipment and method of column type lens plate is provided, can utilize mode of printing to print the light shield layer of column type lens plate.
For reaching above-mentioned purpose, the invention provides a kind of lens pillar panel manufacturing apparatus, in order to make a column type lens plate, the lens pillar panel manufacturing apparatus comprises one first embossing units, one second embossing units and a printing element.Wherein, second embossing units is adjacent to a side of first embossing units.Printing element is adjacent to the opposite side of first embossing units, so that column type lens plate is a part of simultaneously by first embossing units and printing element clamping.
For reaching above-mentioned purpose, the present invention also provides a kind of lens pillar board fabrication method, in order to make a column type lens plate, column type lens plate has a substrate, a lens jacket and a light shield layer, lens jacket is arranged at a side of substrate, light shield layer is arranged at the opposite side of substrate, and the lens pillar board fabrication method comprises: pushing substrate to one first embossing units forms light shield layer in the opposite side of substrate with shape, case-hardened lens layer and the printing that extrudes lens jacket.
From the above, in lens pillar panel manufacturing apparatus of the present invention and method, because the some of first embossing units and printing element clamping simultaneously lens pillar, so can utilize printing element directly on substrate, to print light shield layer accurately.Compared with prior art, because lens jacket also on the lines attached to first embossing units, can't move arbitrarily, so the position of substrate also and then is fixed.Therefore, printing element can utilize printing element to carry out the printing of light shield layer in suitable position in the side of substrate with respect to lens jacket.Thus, can not need the light-sensitive surface and the second UV-irradiation device in the existing lens pillar panel manufacturing apparatus, so can save equipment cost.Moreover, owing to do not need the bonding and the exposure manufacture process of light-sensitive surface, therefore also simplified processing procedure and saved time of processing procedure.In addition, the column type lens plate that manufactures in the present embodiment does not have light-sensitive surface, and photomask is directly and accurately to be arranged on the substrate, and the column type lens plate of this and prior art is also inequality.
