Embodiment Construction

[0034] The technical scheme of the present invention is described in detail below in conjunction with accompanying drawing:

[0035] Such asfigure 1 , figure 2 Shown, a kind of preparation method of plasma display hybrid protective layer comprises the steps:

[0036] The first step: mixing materials: Mg containing 30% to 50% Zn 1-x Zn x O crystals are used as source 1, and Mg containing 0-10% Zn 1-x Zn x O crystal is used as source 2, the particle size of source 1 and source 2 is 200nm-2μm, and then source 1 accounting for 50-70% of the total weight and source 2 accounting for 30-50% of the total weight are mixed to form the source Three 3;

[0037] The second step: liquid preparation: the source three 3 mixed in the first step is dispersed in the volatile organic solvent according to the proportion of 5-10% of the solvent weight used, and it is uniformly dispersed in the solvent through ultrasonic treatment to obtain Spray solution 4;

[0038] The third step: spraying...

Abstract

The invention provides a plasma panel display adopting a mixed protection layer and a preparation method of the mixed protection layer, relating to the technical field of protection layers applied to plasma panel displays. In the invention, an Mg1-xZnxO crystal with Zn content being larger than 30 percent and smaller than 50 percent is used as a first source, an Mg1-xZnxO crystal with Zn content being larger than 0 percent and smaller than10 percent is used as a second source, the first source and the second source are mixed in a certain proportion to form a third source, the mixed proportion is controlled as follows: the first source occupies 50-70 percent of the total weight, the second source occupies 30-50 percent of the total weight, the third source is dispersed into a volatile organic solvent according to the proportion that the third source occupies 5-10 percent of the solvent weight, the third source is evenly dispersed into the solvent by ultrasonic treatment, the solvent is evenly sprayed on the surface of the prepared MgO film by adopting a spray pistol, and the mixed protection layer is formed on the surface of the MgO film when the organic solvent volatilizes. The plasma panel display adopting the mixed protection layer reduces the statistic response time and improves secondary electron emission characteristics.

Description

technical field [0001] The invention relates to the technical field of protective layers used in plasma displays. Background technique [0002] MgO film is a traditional protective layer in plasma devices, such as plasma display devices (PDP), because it has a high secondary electron emission coefficient for Ne ions and is resistant to bombardment of ions, making it a protective layer for plasma devices. layer preferred. However, with the improvement of the resolution of this type of device and the demand for improvement of luminous efficiency, the use of a working gas with a high Xe ratio has become an inevitable development of plasma devices, but the subsequent high ignition voltage and long response time have become new challenges. Therefore, research on new protective layer technology has become one of the important ways to solve these technical difficulties. [0003] Pi oneer company in Japan first prepared a layer of MgO single crystal on the MgO thin film, and used ...
