[Prior Art] - The rear projection display features its large screen and clear image. The rear projection-shadow display has the advantages of no radiation and large size. It can also be connected to a computer or other. Audio and video equipment to achieve the greatest entertainment effect. As a result, as living standards improve and living conditions improve, rear projection displays are increasingly favored by consumers. The rear projection display is distinguished according to its projection technique and can be divided into two types: a cathode ray tube (CRT) and a micro display. Among them, the cathode ray tube display mainly uses a display on the cathode ray tube to enlarge the projection on the screen via an optical system; the micro display uses various different developing units, such as a transmissive liquid crystal panel and a digital micromirror element. (DMD), Reflective Liquid Crystal Panel (LCoS) 'The light emitted by the hemp light source is projected on the screen of the glory. With the improvement of video technology and the demand of the market, in recent years, the microdisplay screen has been widely used in the screen of Rear Projection TV, Monitor Screen, and multimedia display screen ( Multi-screen Installation ) etc. 1285575 Referring to Figure 1, the microdisplay screen 1 is a Transmissive Screen, which is mainly composed of a Fresnel Lens Sheet 11 and a lenticular lens sheet. (Lenticular Lens Sheet) 12 is composed. The incident light from the light source is first incident on the Fresnel lens plate 11 to collect the parallel light, and is incident on the lenticular lens sheet 12. As shown in FIG. 2, the conventional lens plate 12 includes: a plurality of column lenses 121, a transparent substrate 122, a photosensitive film 123, and a light shielding layer 124. The plurality of cylindrical lenses 121 are The photosensitive film 123 is disposed on one side of the transparent substrate 122, and the photosensitive film 123 is disposed on the other side of the transparent substrate 122. The light shielding layer 124 can be adhered by the adhesive portion of the photosensitive film 123. The light shielding layer 124 (also referred to as The black stripe is disposed in the non-focal area of the photosensitive film 123, and the light shielding layer 124 can be used to absorb light to reduce the influence of external light and increase contrast. The lenticular lens sheet 12 is plural. The lenticular lens 121 controls the distribution of light in the horizontal direction to improve the brightness uniformity of the image, and enables the light in the field of view to perform well. Referring to FIG. 3, the manufacturing method of the lenticular lens sheet includes: coating a photo-curable resin on one side of a transparent substrate (S110), embossed and hardened, photo-curable resin (S120), bonded to a photosensitive film on the other side of the transparent substrate (S130), and transfer one Light shielding layer on the photosensitive film (S1 40) Next, referring to FIG. 2 and FIG. 4, in order to manufacture the lenticular lens sheet 12, in the conventional lenticular lens sheet manufacturing apparatus 20, the transparent substrate 122 is transferred to a coating device 21 to light The curable resin is applied to the transparent substrate 122. Then, after the embossing rollers 22, 22' (Embossing Roller) 1285752 press the lines of the plurality of lenticular lenses 121, the first ultraviolet ray irradiator 23 is used for curing.

Referring to Fig. 11, in the present embodiment, the apparatus used in the method of manufacturing the lenticular lens sheet may have different configurations. The first embossing roller Ri and the second embossing roller R2 are positioned vertically by the support rollers of the coating head N2, so that the first embossing roller Ri and the second embossing roller r2 are vertically aligned. In summary, the lenticular lens sheet of the present invention and the method of manufacturing the same are characterized in that the light shielding layer and the lenticular lens layer are formed on the same side of the transparent substrate, which has different structural features from the conventional lenticular lens sheet. . Moreover, since the bonding process of the photosensitive film and the transfer process of the light-shielding film are not required, the complexity of the process is simplified, and the cost of the material and the cost of the process equipment are reduced, but the conventional technology can still be obtained. The same optical effect. Further, the light-shielding layer is formed by printing or by roller forming, and the yield thereof is higher than that of the prior art, by the bonding of the photosensitive film and the transfer process of the light-shielding film to form the light-shielding layer. The above is intended to be illustrative only and not limiting. Any equivalent modifications or alterations to the spirit and scope of the present invention are intended to be included in the scope of the appended claims.
