Problems solved by technology

[0009] Second, in the case where the resistance of the resistor member is too high, when a discharge occurs, the potential difference between the opposite ends of the relevant resistor member becomes large, which can lead to damage of the resistor member
In such a case, as long as the resistor member has an extremely high resistance value, the potential difference between the opposite ends of the resistor member becomes large, and therefore, a secondary discharge may occur, which causes the electrical characteristics of the resistor member to be irreversible deviating from the desired characteristics, resulting in image degradation
[0010] Third, on the contrary, if the resistor member has an extremely low resistance value, when a certain figure is displayed, image quality deterioration called crosstalk or streaking occurs
In particular, in the FED that performs line-sequential driving, the resistive element is divided so that the direction of the power supply line (the direction in which the power supply line extends) is perpendicular to the scanning line, and the deterioration of image quality is easy to expand

example 1

[0065] Made according to the process described below with figure 1 Panels of the configuration shown in . The X direction and Y direction in the following description are figure 1 The X and Y directions are shown in .

[0066] A glass substrate (PD200 manufactured by Asahi Glass Co., Ltd.) having a thickness of 2.8 mm was used as a substrate for the panel 1, and a light-shielding layer (produced by Noritake Kizai Co., Ltd.) was formed on the glass substrate. Manufactured NP-7803D). Next, ribs 7 are formed by photolithography, phosphors 5 for RGB are applied between ribs 7, and phosphors 5 are fired. Subsequently, island-shaped anode layer 6 is formed on phosphor 5 by vacuum evaporation. Finally, the first resistive element 10 and the second resistive element 11 are sequentially formed respectively by photolithography. The pixel pitch is 900 μm, and the width in the X direction of each of RGB is 300 μm. The number of pixels is 100×100 pixels, that is, 300×100 sub-pixels. ...

[0071] Produced by the following process with Figure 4 Panels of the configuration shown in . The X direction and Y direction in the following description correspond to Figure 4 The X and Y directions are shown in .

[0072]On the surface of a clean glass substrate (PD200 manufactured by Asahi Glass Co., Ltd.) with a thickness of 1.8 mm, a black paste (containing black pigment and glass frit) is screen-printed to form on the substrate A pattern of openings in the form of a matrix. In the opening pattern, the size of each opening is 150 μm (X direction) × 300 μm (Y direction), the X-direction pitch of the openings is 200 μm, the Y-direction pitch of the openings is 600 μm, and the formation of 300 sub-pixels in the X direction and An opening corresponding to 100 sub-pixels in the Y direction. The substrate was dried at 120° C. and then fired at 550° C. to form a black matrix (not shown) with a thickness of 5 μm.

[0073] Next, a plurality of ribs 7 are formed in stripes....

Abstract

An image display apparatus comprises a face plate including a common electrode extending in an outside of an image region along a one side of the image region, n first resistor members connected to the common electrode and connected to each of anodes in the divisional regions corresponding thereto, and a second resistor member connecting between one and the other of the first resistor members. R1 is an average resistance value of each first resistor member per length of one pixel including at least one of the light emitting members. R1all is a resistance value of each first resistor member for a total length in the image region. R2 is a resistance value of the second resistor member. And, a relationship of 0.1R1<R2<R1all is met.

Description

technical field [0001] The present invention relates to an image display device, and in particular to the configuration of a resistor member provided on a panel. Background technique [0002] Conventionally, there is known an image display device including a rear plate on which a plurality of electron emission sources are formed and a panel on which electron emission sources in response to collisions with electrons emitted from the electron emission sources and accelerated are formed. and a light-emitting member that emits light. In such an image display device, the interval between the rear plate and the panel is very small, and a high voltage is applied between the rear plate and the panel to accelerate electrons, raising a question of what countermeasures to take against discharge. [0003] Japanese Patent Application Laid-Open No. 2005-251530 discloses an image display device that divides the anode in the row direction. One end of each split anode is connected through ...
