Embodiment Construction

[0019] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0020] figure 1 A device for forming a MgO dielectric protective film with multiple evaporation sources in the prior art shown, the device includes a coating chamber 1, a substrate transport mechanism and a heater 6 are arranged above the coating chamber 1, and an opening plate is arranged at the opening of the coating chamber 1 8. There are four rotating annular hearths 3 (arranged in two rows and two columns) in the coating chamber 1, and four electron guns 2 are arranged on the wall of the coating chamber 1 corresponding to the hearth 3.

[0021] Place the substrate 4 to be coated on the bracket 5 and move it in the horizontal direction through the substrate transmission mechanism. During the movement of the substrate 4, the heater 6 arranged on the upper part of the substrate will heat it to prepare for the next step of coating. In the coating chamber 1,...

Abstract

This invention relates to plasm display screen medium protection film forming device with angle control controlling, which comprises film coating room with base board transmission structure and heater on top, wherein its opening is located with opening board, and its inner side is located with ring stove bed; the film coating room wall is located with electron gun relative to the stove bed; the coating room is also located with angle control device. The invention uses angle control device to effectively control the target angle of the MgO film with good second electron emission parameters and anti-ion impact.

Description

technical field [0001] The invention belongs to the field of video manufacturing, and relates to a thin film forming device, in particular to a forming device of an MgO dielectric protective film of a plasma display screen with an angle control device. Background technique [0002] Color plasma display (PDP: Plasma Display Panel) has the characteristics of large screen, thin profile, wide viewing angle, fast response, high resolution and full digitalization, etc. It is the preferred display device for wall-mounted TV and HDTV. The dielectric protective film is an important part of the color PDP, which is vapor-deposited on the dielectric layer of the front plate and directly in contact with the discharge gas. The basic working principle of color PDP is based on the gas discharge process that occurs on the surface of the dielectric protective film. The performance of the dielectric protective film and the performance consistency on a large area directly affect the performance...
