Problems solved by technology

However, these patents do not actually consider the specific support structure, that is, how the support body is properly placed in the flat panel display.
However, most of the traditional column supports adopt the alignment support structure as shown in Figure 1. This structure has a simple process and is easy to determine the placement position, but its support effect is not very ideal.

Embodiment Construction

[0025] Fig. 1 is the supporting structure diagram (different directions and viewing angles) of the field emission flat panel display that adopts in the prior art, comprises the upper pole plate 1 that is coated with phosphor powder and anode aluminum film, is prepared with the lower of the cathode grid that emits electrons Plate 2 and support body 3 (for the convenience of simulation, the frame glass enclosing the upper and lower plates is not drawn). The size of the upper and lower pole plates is consistent, the length is L, the width is W, the thickness is 2mm, and the distance between the two pole plates is 3mm. A support body 3 is placed between the upper pole plate 1 and the lower pole plate 2, and the support body and the upper and lower pole plates are bonded together with an adhesive. The support body is a small cylinder with a base radius of 0.1 mm and a height of 3 mm. An ultra-high vacuum is maintained between the two plates, while the outside is subjected to atmos...

Abstract

The related inner supporting structure of a large screen flat panel display of field electron emission structure comprises: an upper plate (1), a lower plate (2), and the equal-distance support body (3) between last plates. This invention can decrease the number of supporting column and the exposed area of the support body.

Description

technical field [0001] The invention belongs to the technical field of flat panel display devices, and relates to an internal supporting structure of a large-screen flat panel display with a field electron emission structure. Background technique [0002] It is well known that display devices are widely used in various aspects of information science, and their output value occupies an important position in the information industry. In recent years, flat panel display devices have developed more rapidly. [0003] At present, the main display devices are: CRT (cathode ray tube); LCD-passive (passive liquid crystal display); LCD-active (active liquid crystal display); PDP (plasma display); ELD (electroluminescent display); VFD (vacuum fluorescent display); OLED (organic light emitting diode); FED (field emission display). The Field Emission Display (FED) is one of the new flat panel display technologies, and its luminescence principle is closest to that of a cathode ray tube ...
