Problems solved by technology

[0002] Existing PDP screen burn-in only applies a certain burn-in waveform on the sustain electrodes and scan electrodes of the screen, and the address electrodes are suspended in the air, such as figure 1 , but such an aging method is very prone to electrode short circuit or short circuit. Poor electrode short circuit and open circuit are one of the main defects in the current PDP production process, and they are the bottleneck of quality improvement in the current PDP manufacturing process.

Embodiment Construction

[0028] All features disclosed in this specification, or steps in all methods or processes disclosed, may be combined in any manner, except for mutually exclusive features and / or steps.

[0029] Any feature disclosed in this specification, unless specifically stated, can be replaced by other alternative features that are equivalent or have similar purposes. That is, unless expressly stated otherwise, each feature is one example only of a series of equivalent or similar features.

[0030] Before introducing the technical solution of the present invention, it is necessary to explain why the existing PDP screen burn-in method easily leads to electrode short circuit or open circuit.

[0031] like figure 2 As shown, a PDP screen includes a front glass plate 1 and a rear glass plate 2, and a certain space is formed between the front and rear glass plates. The electrode 4 and the sustain electrode 5 are address electrodes 8 at 145-150 μm below the scan electrodes 4 and sustain elec...

Abstract

The invention discloses a PDP (plasma display panel) aging method and an addressing electrode short-circuit device, relates to the technical field of PDP production, aims at solving the problem that existing aging technology causes electrode short circuits and bad open circuits easily, and provides a novel aging method capable of effectively reducing the phenomena of the electrode short circuits and the open circuits in the process of aging of PDPs and a tool used in the method. The PDP aging method is technically characterized by including the steps: enabling addressing electrodes of a PDP to be in a short circuit, applying aging waveforms on scanning electrodes and maintaining electrodes, and the like.

Description

technical field [0001] The invention relates to the technical field of PDP screen (that is, plasma screen) production, in particular to a PDP screen burn-in method and used tooling. Background technique [0002] Existing PDP screen burn-in only applies a certain burn-in waveform on the sustain electrodes and scan electrodes of the screen, and the address electrodes are suspended in the air, such as figure 1 , but such an aging method is very prone to electrode short circuit or short circuit. Poor electrode short circuit and open circuit are one of the main defects in the current PDP production process, and are the bottleneck of quality improvement in the current PDP manufacturing process. Contents of the invention [0003] The object of the present invention is to address the above existing problems and provide a new aging method and the tooling used therein which can effectively reduce the phenomenon of electrode short circuit and open circuit during the aging process of ...
