Problems solved by technology

As a result, the surface of the separator is charged, and the creep discharge breakdown voltage is greatly reduced or the potential of the surface is changed and the electric field perpendicular to the surface is distorted, so as to have an adverse effect on the electron travel from the electron source, resulting in such as Color Misalignment Phenomenon that Degrades Image Quality

example 1

[0188] The basic structure and figure 1 and figure 2 The structure shown is the same, and the overall structure is shown in Figure 9, wherein, with figure 1 , 2 The same components as 8 are indicated by the same reference numerals. Reference numeral 91 denotes a metal back layer.

[0189] The method of manufacturing the image forming apparatus of the present invention such as Figure 10A to Figure 10H shown. Next, refer to Figure 9 and Figure 10A to Figure 10H The basic structure of the image forming apparatus of the present invention and its manufacturing method will be described. In this example, the substrate 4 itself has the function of the backplane, so in Figure 10A to Figure 10H and Figure 11 It is represented by the label 1 or 4 in it.

[0190] For simplicity, Figure 10A to Figure 10H The electron-emitting devices and the preparatory steps in their vicinity are shown, but this example provides an image forming apparatus formed by a simple matrix arrangem...

example 2

[0228] In this example, the process is the same as in Example 1 up to step h.

[0229] (step i)

[0230] In this example, a small glass plate cut and ground to a size of 1 x 40 x 0.2 mm was cleaned, and an amorphous polyimide solvent (Toray Co. . Toreniece #3000) for spin coating. The spin coating first constitutes a surface (1 x 40 mm face) and the glass sheet is prebaked on a hot plate at 100° C. for 10 minutes. Then, the other side was made by spin coating, and the glass piece was prebaked on a hot plate at 100°C for 10 minutes. Curing was performed by placing the coated glass sheet in a clean oven, raising the temperature from room temperature to 300°C, and then maintaining the glass sheet at 300°C for one hour. The polyimide resin thus obtained had a thickness of about 1 µm.

[0231] (step j)

[0232] On the upper wiring 7b of the backplane 1 at the position for placing the spacer, Toreniece #3000 was applied with a dispenser to temporarily fix the spacer 11 prepared...

example 3

[0253] In this example, the process is the same as in Example 1 up to step h.

[0254] (step i)

[0255] In this example, a cleaned glass rod with a diameter of 0.2 mmφ was diluted five times in volume with N-methyl-ethylpyrrolidone by immersing and detaching the glass rod from the liquid. ) for dip coating. Pre-bake the raised glass rod in a clean oven at 100°C for 10 minutes, and proceed by placing the glass rod in a clean oven, raising the temperature from room temperature to 300°C and maintaining it at 300°C for one hour solidify. The polyimide resin film thus obtained had a thickness of about 1 µm.

[0256] This glass rod surface-coated with polyimide resin was cut into a length of 1 mm to obtain a plurality of cylindrical partitions 11 .

[0257] (step j)

[0258] At the position for placing the spacer on the upper wiring 7b of the back plate 1, Toreniece #3000 was applied with a dispenser to temporarily fix the spacer 11 prepared in step i. In this operation, the ...

Abstract

An image-forming apparatus comprises a rear plate on which an electron-emitting device is provided, a face plate having an image-forming member and arranged to be opposed to the rear plate, and a spacer provided between the face plate and the rear plate. The spacer comprises a spacer base plate and a coating layer including organic resin and carbon. At least part of the carbon is exposed from the surface of the coating layer. The image-forming apparatus displays an image with a high luminance and a high color saturation over a prolonged time.

Description

technical field [0001] The present invention relates to a spacer provided in a housing including electron-emitting devices, an image forming apparatus including electron-emitting devices, an image forming member, and a spacer in the housing, and a method of manufacturing the same. Background technique [0002] As an image forming apparatus using electron-emitting devices, there is known a planar type electron beam display panel in which an electron source substrate on which a plurality of cold cathode electron-emitting devices is formed and an anode substrate including a transparent electrode and a fluorescent member The sheets are opposed in parallel, and the display panel is evacuated. [0003] For example, I. Brodie discloses an image forming apparatus using a field electron emission device in such an image forming apparatus in "Modern Technology: Planar Cold Cathode CRT" in Information Display, 1 / 89, 17 (1989). . For example, another image forming apparatus using plana...
