Abstract

A kind of ultrathin wide-screen television comprises television circuit, picture tube, it is characterized in that: picture tube is screen, phosphor screen and display screen three parts exceptionally, extremely are arranged in parallel for a short time from big successively, are the three-dimensional trapezoidal shape of vacuum; Shield outward to close and form by two lightweight polymethyl methacrylate moulds, in be the vacuum shape, wherein one is outer flat arc, another piece is two-sided parallel, is carved with anti-folding circle of light and light on the cambered surface of flat outside arc polymethyl methacrylate and prevents break; The fluorescence structure shape is consistent with outer screen, and its size is successively decreased in proportion; Display screen is small-sized liquid crystal display screen; Sprayed the layer of fluorescent powder layer on the cambered surface of outer flat arc polymethyl methacrylate.The utility model compared with prior art owing to adopted the straight saturating principle of rear-projection, adopts the technological means of small-sized liquid crystal display screen, secondary phosphor screen and outer screen, be made into special picture tube, reached the effect of ultra-thin wide screen television, it is low to have cost of manufacture, simple in structure, good effectiveness.

Description

A kind of ultrathin wide-screen television

Affiliated technical field

The utility model belongs to a kind of large-scale ultra-thin television.

Background technology

Along with improving constantly of science and technology development and living standards of the people, the television set industry develops towards slimming, maximization and high definition direction.The image display panel relative thickness of television sets 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 television set 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 television set 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.

Summary of the invention

For solving the deficiencies in the prior art, the utility model provides a kind of ultrathin wide-screen television, this television set not only image definition, thickness etc. can reach the effect of the large-scale ultra-thin television of liquid crystal fully, but cost of manufacture reduces significantly, and the television set of equal specification has only about 1/8th of liquid crystal TV set.

A kind of ultrathin wide-screen television of the utility model, it comprises television circuit, picture tube, it is characterized in that: picture tube is screen, phosphor screen and display screen three parts exceptionally, extremely are arranged in parallel for a short time from big successively, are the three-dimensional trapezoidal shape of vacuum; Shield outward to close and form by two lightweight polymethyl methacrylate moulds, in be the vacuum shape, wherein one is outer flat arc, another piece is two-sided parallel, is carved with anti-folding circle of light and light on the cambered surface of flat outside arc polymethyl methacrylate and prevents break; The fluorescence structure shape is consistent with outer screen, and its size is successively decreased in proportion; Display screen is small-sized liquid crystal display screen; Sprayed the layer of fluorescent powder layer on the cambered surface of outer flat arc polymethyl methacrylate.

During concrete enforcement, the density that is provided with of the anti-folding circle of light is every centimetre of 8-10 circle, and the anti-break of light is shaped as equilateral triangle, is equipped with the anti-break of 5 light on every centimetre the arc length, and cross arrangement.

Outer screen gross thickness is 1.2 centimetres, and phosphor screen is 1 centimetre, and outer screen is spaced apart 3-4 centimetre with phosphor screen, phosphor screen and display screen be spaced apart 3-4 centimetre.

Beneficial effect: the utility model compared with prior art, owing to adopted the straight saturating principle of rear-projection, according to different size, phosphor screen and the organically combination of outer screen with different size, adopt the technological means of small-sized liquid crystal display screen, secondary phosphor screen and outer screen, be made into special picture tube, reached the effect of ultra-thin wide screen television, and cost of manufacture is low, and is simple in structure, effective.

Description of drawings

Fig. 1 is the vertical profile structural representation;

Fig. 2 is that K is carved with anti-folding circle of light and the anti-break of light to structural representation among Fig. 1 on the cambered surface of the outer flat arc polymethyl methacrylate 4 of main expression among the figure.

Embodiment

Referring to Fig. 1, Fig. 2, sequence number is represented respectively among the figure: shield 1 outward, shield outer polymethyl methacrylate 2 outward, internal layer polymethyl methacrylate 4 is shielded at the interior interval 3 of outer screen outward, outer screen and phosphor screen interval 5, phosphor screen arc polymethyl methacrylate 6, interval 7 in the phosphor screen, the flat shape polymethyl methacrylate 8 of phosphor screen, phosphor screen and display screen interval 9, display screen 10, shell 11, the anti-folding circle 12 of light, light is prevented break 13.

The utility model is described in further detail by embodiment below in conjunction with accompanying drawing.

This ultrathin wide-screen television, except that television circuit, picture tube exceptionally shields 1, phosphor screen 6,8 and display screen 10 3 parts, successively from big to being arranged in parallel for a short time, be the three-dimensional trapezoidal shape of vacuum; Outer screen 1 is by two blocks of lightweight polymethyl methacrylate promptly: shield outer polymethyl methacrylate 2 outward, shield internal layer polymethyl methacrylate 4 moulds outward and close and form, in be the vacuum shape.The gross thickness of outer screen 1 is 1.2 centimetres, and phosphor screen 6,8 is 1 centimetre, and every cambered surface center thickness is 0.4-0.8 centimetre, shield outward 1 with phosphor screen 6,8 be spaced apart 3-4 centimetre, phosphor screen 6,8 and display screen 10 be spaced apart 3-4 centimetre.The outer polymethyl methacrylate 2 of outer screen is outer flat arc, has sprayed the layer of fluorescent powder layer on its cambered surface.Outer screen internal layer polymethyl methacrylate 4 be two-sided parallel, shields outward to be carved with the anti-folding circle 12 of light on the cambered surface of outer polymethyl methacrylate 2, phosphor screen arc polymethyl methacrylate 6 and light is prevented break 13; Phosphor screen 6,8 planforms are consistent with outer screen 1, and its size is successively decreased in proportion, with outer screen 1 except that size is had any different, do not have the sprayed with fluorescent powder layer on its cambered surface; Display screen 10 is small-sized liquid crystal display screen, and it is about 1/10th sizes of outer screen 1.

During concrete enforcement, the density that is provided with of the anti-folding circle 12 of light is every centimetre of cambered surface 8-10 circle, and the anti-break 13 of light is shaped as equilateral triangle, is equipped with the anti-break of 5 light on every centimetre the arc length, and cross arrangement.

Television circuit partly adopts the structure of LCD TV circuit, and just the improvement of carrying out on the light beam electron gun increases brightness, definition to some extent.
