Problems solved by technology

[0018] However, the commonly used PbO base dielectric material is limited in permittivity improvement because it reduces the internal voltage with increasing permittivity
Moreover, when using materials with the same dielectric constant and reducing the thickness to increase the electrostatic capacity, it is difficult for the original dielectric to withstand the internal voltage of about 560V

Embodiment Construction

[0031] The present invention will be described in detail below through various specific embodiments.

[0032] The present invention uses ceramic materials with high dielectric constant and high insulation resistance to increase the electrostatic capacity on the upper / lower plate dielectrics constituting the PDP element, and on the other hand, applies the dielectric with high internal pressure characteristics to the PDP element , in order to improve the resistance of the discharge voltage. Not only that, but ferroelectric ceramic materials are applied to the phosphor, which can induce some reflection of visible light while increasing the electrostatic capacity to improve luminance and efficiency. The above-mentioned increase in electrostatic capacity means reduction of jitter phenomenon, and can also alleviate low-temperature / high-temperature discharge.

[0033] Because the ferroelectric ceramic material that can be applied in the present invention is used to improve the dielect...

Abstract

The invention uses strong dielectric film on top / bottom dielectric to enlarge discharge voltage and static capacitor to prevent jitter and misdischarge at low / high temperature for plasma display element. Wherein, the key hard to fast drive current plasma display is the dielectric material based on pbo with lower inner voltage. This invention provides jitter compensation to overcome the problem and improves brilliance and efficiency.

Description

【Technical field】 [0001] The present invention relates to jitter-compensated plasma displays. More specifically, ferroelectric thin films are applied on the dielectric of the upper / lower plates to increase discharge voltage and electrostatic capacity, thereby preventing jitter and low / high temperature misdischarge from occurring. 【Background technique】 [0002] Plasma displays that receive footlight by using TFT (thin film technology) liquid crystal display elements and next-generation display elements such as organic EL (organic electroluminescent display technology) and FED (field emission display) are separated by partition walls. He+Xe, Ne+Xe gas discharge is caused in the discharge unit to generate 147nm ultraviolet rays, and then the ultraviolet rays are used to activate the RGB three-color phosphor, relying on the energy difference generated during the process of the phosphor returning from the gas state to the basic state. A display element that causes luminescence. ...
