Abstract
The utility model discloses a color kinescope, mainly solving the technical problem of reducing the weigh of the bulb. The utility model adopts the technical proposal that: the color kinescope is provided with a glass bulb made up by a TV panel and a glass envelope, wherein, the TV panel is a float glass paned, the connection point of the glass envelope and the TV panel extends, the outside of the TV panel is plated with glare shield film. Compared with the prior art, the float glass panel is connected with the glass envelope, which reduces the weight of the kinescope and maintained the vacuum performance of the color kinescope and is applicable to the monitoring device.
Description
Technical field
The utility model relates to a kind of picture tube, particularly a kind of small sized colour picture tube.
Background technology
Color picture tube is applied to family and monitoring arrangement, known common picture tube glass bulb is to be made of glass screen and glass awl, glass screen and the low-melting glass melt welding of glass awl, the glass screen that adopts mold pressing to produce, with respect to the glass awl, the thickness of glass screen wants much thick, and not only the weight of whole glass bulb is big, and cost is higher, has limited the extensive use of picture tube.
Summary of the invention
The purpose of this utility model provides a kind of color picture tube, and the technical problem that solve is the weight that alleviates glass bulb, and another technical problem to be solved in the utility model is protection beholder's a eyesight.
The utility model is by the following technical solutions: a kind of color picture tube, a glass bulb that is made of glass screen and glass awl is arranged, and described glass screen is a float glass flat board, described glass awl and the junction prolongation of glass screen.
The thickness of float glass flat board of the present utility model is 4 millimeters.
Glass screen outer surface of the present utility model is coated with antiglare film.
The casing diameter of the utility model glass awl is 22 millimeters.
Crt screen of the present utility model is of a size of 2.5 to 5.7 inches.
The utility model compared with prior art adopts dull and stereotyped the awl with glass of float glass to be connected, and has alleviated the weight of picture tube glass bulb, reduced the cost of glass bulb, and keeping the electrovacuum performance of color picture tube constant, glass screen outer surface is coated with antiglare film, can alleviate beholder's asthenopia.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1; the glass bulb of color picture tube of the present utility model is made of glass screen 1 and glass awl 2; what glass screen 1 adopted is the float glass flat board of 4 millimeters thick; its physical vacuum property retention is constant; for keeping the size constancy of glass bulb; glass awl 2 and the dull and stereotyped 1 junction extend outwards of float glass; to guarantee that electron beam focuses on the phosphor screen; glass shields 1 outer surface and is coated with antiglare film 3; eyesight with the protection beholder; the cover neck diameter of glass awl is 22 millimeters, and the crt screen size can be to be 2.5 to 5.7 inches.When making picture tube, glass awl 2 after handling is gone up the low-melting glass bonding material along dripping on the awl mouthful limit, press fit in the frock with float glass flat board 1 again through preceding working procedure processing, put into low banking roasting sealing-in, Φ 22 electron guns of in the sleeve pipe of glass awl, packing into afterwards, through seal, operation such as exhaust makes color picture tube.
Claims (5)
1. a color picture tube has one by the glass bulb that glass shields and the glass awl constitutes, and it is characterized in that: described glass screen is a float glass flat board, and described glass awl shields the junction with glass and prolongs.
