Abstract

The invention discloses a plasma display screen of a PDP discharge electrode. The structure of the plasma display screen comprises back glass, a barrier wall, front glass, a transparent electrode, fluorescent powder and an addressing electrode. The back glass is parallel to the front glass; fluorescent powder is arranged on the back glass and is separated by the barrier wall; the barrier wall is connected between the front glass and the back glass; a transparent electrode is arranged in the front glass; the addressing electrode is arranged in the back glass; the barrier wall comprises a body,a cooling structure and movable structures. The movable structures are arranged on the two sides of the end, close to front glass, of the body. The cooling structure is arranged in the middle of the body. The plasma display screen has the beneficial effects that cooling is conducted through heat exchange between external cold air and the interior of the plasma display screen, rapid air draft can be conducted through the air draft structure when the temperature is high, the instantaneous cooling speed is increased, the movable block can move so that the internal space can be enlarged, and damage to the device due to air expansion is prevented.

Description

technical field [0001] The invention relates to the field of PDP plasma flat display screen, in particular to a plasma display screen of PDP discharge electrodes. Background technique [0002] The ion display panel is a vacuum chamber that uses He+Xe, Ne+Xe, He+Ne+Xe or He+Ne+Kr+Xe and other inert mixed gases to generate vacuum ultraviolet rays of about 147nm, so that the phosphor emits light to achieve our Visually perceptible text and images. [0003] When the existing plasma display screen is in use, the internal electrodes generate heat, and the interior is in a vacuum-sealed state. Serious heat generation can easily expand the internal air and cause the glass to break. SUMMARY OF THE INVENTION [0004] The main purpose of the present invention is to overcome the deficiencies of the prior art and provide a plasma display screen with a PDP discharge electrode. [0005] The present invention adopts the following technical scheme to realize: a plasma display screen of P...
