Abstract

The invention discloses a plasma display panel and a front substrate thereof. The front substrate comprises a plurality of pairs of maintaining electrodes distributed on the lower surface of the front substrate, front medium layers covered on the maintaining electrodes and the lower surface of the front substrate, and protective layers covered on the lower surfaces of the front medium layers; each pair of the plurality of pairs of maintaining electrodes comprise public electrodes and scanning electrodes, the public electrode and the scanning electrodes all comprise bus electrodes and transparent electrodes, wherein each transparent electrode comprises a discharge transparent electrode, an extending transparent electrode which extends from the top of one of a plurality of first retaining walls on a rear substrate of the plasma display panel and is connected with each bus electrode, and a connecting transparent electrode connected with the discharge transparent electrode and the extending transparent electrode; and the bus electrodes are arranged on one of a plurality of second retaining walls on the rear substrate of the plasma display panel and a place corresponding to one of the second retaining walls.

Description

technical field [0001] The invention relates to the field of displays, more specifically to a plasma display screen and its front substrate. Background technique [0002] Plasma display (PDP) can be divided into two categories according to the driving method, namely DC PDP (DC-PDP) and AC PDP (AC-PDP), and can also be divided into two categories according to the electrode structure, namely two-electrode type PDP and three-electrode type PDP. Mainly adopt AC-PDP at present. [0003] According to the setting of the discharge electrodes, the AC-PDP can be further divided into a facing discharge type PDP and a surface discharge type PDP. For the surface discharge PDP, the two sustain electrodes are on the same substrate, and the address electrodes are provided on the other substrate. [0004] The surface discharge type AC-PDP display screen is composed of two substrates. The structure of the front substrate (the first substrate) is as follows: under the front substrate, there...

Problems solved by technology

The mechanism is that if the width of the extended transparent electrode 51a is too small, the resistance of the PDP increases significantly, so the brightness of the PDP decreases, thereby reducing the luminous efficiency.

On the other hand, if the width of the extended transparent electrode 51a is too large, the width b of the first barrier rib 30b is too large, the extended transparent electrode 51a protrudes from the side of the vertical unit 30b to reduce the aperture ratio of the PDP, and due to the discharge The sharp increase of current reduces the luminous efficiency of PDP

[0009] But when figure 1 In the structure shown, there are disadvantages of large screen capacitance and low effective capacitance, so it is difficult to further improve the discharge efficiency
