Plasma display screen

Abstract

The invention discloses a plasma display screen. The plasma display screen structurally comprises a heat dissipation plate, a horn mouth, a shading device, a display screen, a rotating device and a base, when the device is used, the operation is simple; the display screen is used for playing the ornamental content; the shading plate is fixed to the display screen through the connecting holes, theshading plate and the display screen are connected for protection through the clamping blocks, the shading strip is attached to the shading plate through the corrugated guide parts, the shading stripis matched with the shading plate through the sealing film, light of the display screen is prevented from leaking out of the side edge, the shading strip and the shading plate are matched for shading,and the viewing quality is improved. When an ornamental person sits on the side edge of the display screen; the adjusting disc adjusts the angle of the display screen; according to the display screenadjusting device, the angle of the display screen is adjusted by rotating the swing block, the friction stop plate is attached to the clamping plate on the outer ring of the adjusting disc, the stopblock and the buffer plate stabilize the adjusting disc at the adjusting and using position under the action of mutual force, people sitting on the side edge can clearly view the content on the screen, and the viewing effect is improved.

Description

technical field [0001] The invention relates to the technical field of plasma display screens, in particular to a plasma display screen. Background technique [0002] The plasma display screen is mainly composed of front and rear substrates and functional devices such as electrodes, barriers, dielectrics, and phosphors made on the substrates. The front and rear substrates are sealed at high temperature by sealing materials around the display area to form a hermetic seal. Cavity, the closed cavity is vacuumed and exhausted, and then filled with an appropriate amount of mixed inert gas, and an appropriate alternating voltage is applied to the display electrodes, and a vacuum discharge occurs in the closed cavity, and the inert gas generates vacuum ultraviolet rays to excite the tri-color phosphors to emit light. . When the plasma display screen is in use, it needs to be improved: [0003] 1. When the plasma display screen is viewed in a bright environment, the light is too s...

Problems solved by technology

[0005] Aiming at the deficiencies in the prior art, the object of the present invention is to provide a plasma display screen to solve the problem that when the plasma display screen is viewed in a bright environment, reflections appear on the display screen due to too strong light, which makes viewing the display screen difficult. When the image is very unclear, the quality of viewing will be reduced, and the use effect of the plasma display will be reduced; When the people on the side are watching, they will not be able to completely watch the content on the display screen due to reflection or angle reasons, which will reduce the viewing effect.
