Embodiment Construction

[0027] By below Figure 1-7The present invention will be described in detail, in which it is convenient, and now, the orientation of the following statement is as follows: The above-mentioned left and right directions and figure 1 Itself around the vertical projection relationship of consistent direction.

[0028] Join Figure 1-7 Induction chamber 28 of the inner shell a PDP flat panel display, the display frame 10 includes a PDP, the PDP display frame 10 is attached to the rear end of the pressure sensing chamber housing 28, the air pressure actuation mechanism comprises a pressure detector 51, the said pressure detecting means 51 can start sensing the pressure change, thereby automatically start timing determination device, 28 located on the front side of the pressure sensing chamber housing PDP display frame 10 is attached to the power rod 23 filaments, the filament power the lever 23 is rotatable on the PDP display frame 10, the filament power lever 23 is attached to a left end...

Abstract

The invention discloses a PDP (Plasma Display Panel)two-dimensional display which comprises a PDP display outer frame, an air pressure sensing cavity shell is arranged at the rear end of the PDP display outer frame, an air pressure detection starting mechanism is arranged in the air pressure sensing cavity shell, and the air pressure detection starting mechanism can sense air pressure changes so as to automatically judge the starting time of equipment. The PDP two-dimensional display can automatically change the air pressure according to the air pressure, ensures that the PDP two-dimensional display is unfolded when the external air pressure of the PDP display is reduced to reach a screen working critical value, absorbs the pressure on the screen glass plate by increasing the stress area, and reduces the huge pressure caused by the air pressure difference between the two sides of the screen of the PDP display, therefore, it is ensured that the PDP display can be used in some critical use areas or areas with large air pressure changes, the safety of a screen of the PDP display and surrounding people is protected, and economic losses are reduced.

Description

Technical field [0001] The present invention relates to the field of display applications, particularly as a PDP flat panel display. Background technique [0002] PDP display because of its own characteristics, and the front glass plate to be sealed between the glass plates filled with inert gas work, so most of the production of PDP display 2600 meters above sea level can not work, but used at high altitude is below 2600 m the risks, because the higher elevation such that the smaller the pressure, but the pressure decreases, thereby causing the pressure difference inside and outside the screen gradually becomes larger, but the outside atmospheric pressure reduced to a certain extent, the display will hum, if the pressure difference is too large or even damage can occur. Inventive content [0003] The present invention is to solve the technical problem of providing a PDP flat panel displays, flat panel displays used to solve the PDP will be damaged in the situation of low pressu...
