example

[0074] In the field emission display panel of this example, each sub-pixel area is provided with a first resistance element and a second resistance element. The structure of the sub-pixel area of ​​the field emission display panel of this example is as follows Figure 2A-Figure 2C or Figure 3A-Figure 3C Shown. In addition, in this example, the voltage applied to each sub-pixel area by the external circuit is about 35V, the resistance value of the external circuit is about 3KΩ, and the first conductive layer 102 (the first electrode and the first electrode line) is given about 0V. . When electrical measurements are performed on three of the sub-pixel regions (sub-pixel regions 1, 2, and 3) of the field emission display panel of this example, the results shown in Table 1 can be obtained.

Abstract

The invention provides a field emission type display panel, which comprises a substrate provided with at least a display region and a non-display region. A first conductive layer disposed on the display region comprises a first electrode line and a first electrode electrically connected with the first electrode line. A resistance material layer is positioned on the first conductive layer in the display region. An insulating layer covering the resistance material layer in the display region is provided with a first opening and a second opening. Part of the resistance material layer above the first electrode is exposed through the first opening. Part of the resistance material layer above the first electrode line is exposed through the second opening. An electronic emission element is arranged on the resistance material layer exposed through the first opening. A second conductive layer disposed on the insulating layer is positioned in the second opening. The second conductive layer comprises a second electrode line and a second electrode electrically connected with the first electrode line. The second electrode is provided with a third opening so as to expose the electronic emission element. At least a first sub-pixel region and a second sub-pixel region are defined through the second electrode line and the first electrode line.

Description

Technical field [0001] The present invention relates to a display panel, and particularly relates to a field emission display panel. Background technique [0002] Generally speaking, field emission display panels are mainly used in an ultra-high vacuum environment (less than 10-6 toll) to fabricate an electron emitter on the cathode, and use the high aspect ratio of the electron emitter. aspect ratio) to help electrons overcome the work function of the cathode and escape from the cathode. In addition, in a field emission display panel, if phosphor powder is coated on the anode, and the high electric field between the cathode and the anode causes the electrons to be taken out from the electron emission end of the cathode, the electric field directly impacts the anode on the anode. Phosphors can emit visible light. [0003] The problem faced by the current field emission display panel is that the uniformity of the luminous brightness of the display panel is insufficient. In other ...
