Abstract

The utility model directs to an image multiplication display screen. A section of the display screen is rectangular and horn-shaped. A magnifying lens a concave lens and a convex lens are vertically disposed inside the display screen from the left to the right. Two sides of a three-surface lens are respectively a plane and a cambered surface. The cambered surface is gradually thinner and thinner from the center to the around edges. The plane of the convex lens is inscribed with annular refracting rings. Anti-refracting point is arranged between the adjacent refracting rings. A surface of the magnifying lens is on the right of a left cambered surface. The cambered surface of the convex lens is on the right of a left plane. The surface of the concave lens is on the right of the left cambered surface. An interval is arranged between the concave lens and the magnifying lens. The surface of the convex lens is molded with the surface of the concave lens. A partition plate with a sliver-gray grounding color seals and incorporates the three-surface lens externally. The right side of the partition plate is provided with a window for an LCD. The utility model arranges three lens of different requirements at a view angle of multiplying the images, and inscribes one lens of three lens with refracting rings and anti-refracting points, thereby resolving the problem that the refraction from the source image to the objective image is disordered so that the image is more lifelike; also, uses the technical means of molding the convex lens and the concave lens to resolve the defects that, visually, the image is not on the surface layer of the display screen.

Description

Image amplifies display screen

Affiliated technical field

The utility model belongs to a kind of image display panel, relates in particular to a kind of used as television image display panel, and it can be enlarged into large-scale picture image with little picture image.

Background technology

Along with improving constantly of science and technology development and living standards of the people, the televisor industry develops towards slimming, maximization and high definition direction.The image display panel relative thickness of televisors such as radium-shine, liquid crystal in the market is relatively thinner, weight is low weight, but price is very expensive, for example 43 inches back projection type televisor thickness are between the 50-70 centimetre, price is wanted about 20,000 yuan, and the slim TV machine more than 70 inches does not also have product to come out.For most of family particularly for most rural households, because the manufacturing cost of above-mentioned televisor is too high, also there is sizable contradiction in the supply and demand, make 2.4 meters of directors now, wide 1.6 meters large-screen receiver, its expense needs more than 100,000 yuan, makes most consumers forbidding.

Chinese patent " television image amplify screen (patent No. 002073439) ", " a kind of ultrathin televisor (patent No. 012111341) " are split and are sent out large-screen receiver cheap and good-quality and done useful trial.The characteristics of this televisor are: circuit part adopts the television circuit more than 17 inches, and kinescope adopts the liquid crystal video screen below 7 inches after reequiping.Then, amplify the comprehensive amplification of display screen, make large-screen receiver by the image that is arranged on the video screen dead ahead.But the image of this type of televisor amplifies its image of display screen and visually also has certain deficiency, panesthesia to image not on the top layer of screen.

Summary of the invention

The purpose of this utility model provides a kind of display screen with zoom function, it matches with the LCDs of above-mentioned technology, fit together, not only can show large-screen image, and have the better pictures sharpness, visually reach the purpose that image is presented on target screen scene plot layer fully.

Structural feature of the present utility model is: the rectangular trumpet-shaped display screen in cross section, inside vertically is equipped with magnifier, convex lens, concave mirror from left to right, the two sides of three mirror contact lens is respectively plane and cambered surface, gradually thin around the mind-set in the cambered surface, be carved with annular refractive power circle on the plane of convex lens, be carved with anti-break between the adjacent refractive power circle; The plane of magnifier in left cambered surface on the right side, the cambered surface of convex lens on left plane on the right side, the plane of concave mirror in left cambered surface on the right side; Have spacing between convex lens and the magnifier, the plane mould of its plane and concave mirror closes; Outside is that silver-gray dividing plate unifies the three mirror contact lens sealing by background color, and right-hand member is the LCDs window.

The center thickness of magnifier, convex lens, concave mirror is 3-5CM, and edge thickness is 0.2-0.5CM.

The refractive power circle is decided on enlargement ratio, if 160CM is long, and the display screen that 120CM is wide, its live width is 1MM, line is 0.5MM deeply, distance between centers of tracks 2MM.

Prevent the equilateral triangle that is shaped as of break, the ring heart of refractive power circle is pointed at an angle, and all anti-breaks begin to be the radial arrangement that misplaces at interval from the ring heart.

The beneficial effects of the utility model are: from the angle that image can be amplified, three different mirrors that require are set, and scribe refractive power circle and anti-break on a minute surface therein, thus solved the disorder phenomenon of source images to the target image anaclasis, make image more true to nature; The technological means that adopts concave and convex lenses plane mould to close has solved image visually not in the defective on screen top layer.
