Description

471238

This case is an addition (1) to the patent application No. 8 1 1 3 6 80 (hereinafter referred to as the mother case), which is a light emitting element and process, especially a light emitting element and process having a carbon micro tube emission source. As mentioned in the mother case, the display of high efficiency and power saving can be applied to many organizations that need to convey information, such as score boards in large sports stadiums, electronic display boards in public places, road signs on highways, traffic conditions displays, etc. ' It is very versatile. The display screen used in large electronic sign boards is a display technology composed of many small light-emitting elements. Currently, the technology for making these small light-emitting elements is incandenscent light.

bulbs) 'small cathode ray tube (smaii cathode ray tube CRT), high pressure vacuum fluorescent tube (highvo 11 agevacuumf 1 uorescent display HVVFD), small fluorescent lamp (smaii fluorescent Ump), and light emitting diode (light emitting diode ) Wait for five. Incandescent light bulbs are based on the principle of heating and emitting light from the filament in the light bulb. Since the temperature of the filament (tungsten wire material) in the light bulb must be maintained at 900-500 ° C during light emission, the display panel composed of incandescent light-bulbs is very power-hungry. Energy efficiency is very low. At the same time, an incandescent light bulb emits only yellowish white light, so it is very difficult to form a color display board.

The cathode ray tube system uses an electron beam to strike the phosphor to emit light. This type of light emission is very high in luminescent efficiency. Therefore, in theory, the energy efficiency of CRT should also be very high. However, the source of electrons in CRT is A hot cathode made by coating an oxide (such as barium oxide) that easily releases electrons on the surface of a heated metal.

Page 4 471238 V. Description of the invention (2) When hot, these oxides can release hot electrons. Because the electron gun that generates electrons is a point electron source, it is necessary to increase the temperature of the electron gun, that is, to increase the current of the electron gun, in order to obtain a high electron density. The current of the electronic grab will inevitably lead to a shorter life of the electronic grab and increase energy consumption. On the other hand, the CRT itself is bulky, and the shortcomings of being thick and heavy make it limited when combined into a large display panel, and cannot form a display screen that can display fine pictures. The display screen composed of small C r τ consumes a lot of power, and the 25m χ 4 0m composed of small CRTs in current products shows that the energy consumption of Kanban is up to 20 KW, although it only reaches 1/10 of incandescent bulbs, but because of Due to the limitation of the electron source, the high luminous efficiency of the phosphor cannot be exhibited. High-pressure vacuum fluorescent tube (HVVFD) is to improve the point electron source in the CRT into a line electron source. The wire electron source is coated with an oxide that easily emits electrons on a thin tungsten wire. Since the linear electron source can emit many hot electrons to hit the phosphor to emit light, the CRT can greatly improve the energy consumption. Shortcomings. At the same time, HVVFD can coat the three primary colors of red, blue, and green on a light-emitting unit. Therefore, combining HVVFD with a color display screen is easier than CRT, and its analytical output is higher than CRT. & Although the display screen composed of HVVFD has better characteristics and energy consumption than a screen composed of a small CRT, HVVFD has a complicated structure and is very difficult to manufacture. At the same time, the heating of tungsten electrons with tungsten filaments still consumes a lot of energy. 2.5 m X 4 0 m display with current Η VVFD combination

Page 5 471238 V. Description of the invention (3) Act, the high power consumption is still about 1,000OkW. A small fluorescent lamp made by using ultraviolet light to excite fluorescent powder can also form a display screen. However, the current fluorescent lamp components are limited by the color, and the size of each fluorescent lamp is difficult to reduce. 1 line / mm, below, so it is extremely difficult to form a fine daytime surface. Non-glowing light emitting diode LEDs are also widely used in large display screens. Although materials that can emit three primary colors of red, blue, and green have been developed, the production of high-brightness green and blue materials is difficult. At the same time, the luminous efficiency can be as high as 30 im / w compared to phosphors. To ίο im / w, in addition to low luminous efficiency, LEDs have serious view angle problems, causing defects in the use on large screens. The mother case also mentioned that the conventional light-emitting elements have the following disadvantages: (1) The efficiency is not high, the light-emitting efficiency is too low, and it cannot be used for large screens. (2) Energy consumption. Due to the light-emitting characteristics of light-emitting elements, energy consumption may occur extremely. (3) The resolution is low and it is limited by the arrangement and color of the light emitting elements, so it is difficult to form a fine picture. The mother case is to propose an improved light-emitting element based on the lack of custom. It analyzes the advantages and disadvantages of the existing elements systematically and systematically, and attracts new materials. The new structure invents a display element with high brightness and high resolution. , This element: = large electric signboard (electric b〇ard) including static text messages and moving image messages.

471238 88113680A01 Corrected the analysis of luminous elements of thorium, we found that the luminous efficiency of using electrons to strike phosphors is higher than other luminous technologies. Therefore, small CRTs and HVVFDs are more efficient than white iron bulbs, light-emitting diodes, etc. The light emitting element is high. However, in small CRT and HVVFD components, the method of generating thermionic electrons by heating is the main cause of energy consumption. A cold cathode that wants to reduce this energy consumption ’field emission is the best choice. In 1 995, Rinzler first learned of Shi Nai in "A simple and robust eletron beam source from carbon nanotubes" by Philip G Collins and A Zetth Appl. Phys. Le 11. 6 9 (1 3), 1 9 9 6 The carbon micro tube (carbon nan〇-tube) composed of the material has the characteristics of emitting electrons. In 1997, Wang et al., Field Emission from nanotubes bundle emitters at low field " by QH Wang, TD Corrigan, JY Dai and RP H · Chang, AR · Krauss, Appl. Phys · Let, 70 (24), 1997 proposed that as long as the carbon microtube can release a large number of electrons at a low electric field of 0.8 V / zm. Therefore, 'as long as the characteristics of carbon microtubes can release electrons under a low electric field and the high-efficiency light-emitting characteristics of fluorescent powder can be made high-brightness, energy-saving' South-precision light-emitting elements' such light-emitting elements can be combined It can display monochrome or color display screens to display electronic signboards including static text and dynamic messages. The mother case reveals a component that uses a carbon microtube microelectronic emission source to emit electrons to strike the phosphor to achieve the purpose of emitting light. At the same time, the high brightness and energy saving characteristics of this component are used to form a power-saving, single-color or multi-color Or all

Adjacent to the gate, the electron is received and the light is generated with the luminescent substance. Example 1 of the mother case: two-pole red, blue, and green light-emitting elements The mother case has three primary colors of red (R), blue (G), and green (β). The structure of the light-emitting element is shown in Figure 1. The upper panel 13, BM11 in the figure is black㈣ 忖 for added contrast.

R, G, and B are red, green, and blue phosphors, respectively. There is also an aluminum layer on the upper panel, which can increase reflection. The lower plate is formed with a conductive line i9 on the glass substrate 7. The conductive line 19 is a carbon micro tube 18, and the carbon micro tube 18 is a mesh structure made of a porous conductor as a grid 16. The upper and lower panels are separated by glass as% ^ 15, and the entire unit structure is sealed in a vacuum environment like CRT and VFD. In this structure, as long as an electric field (ie · 0.8 v / em) is applied between the grid 16 and the carbon microtube 18 to cause the microtube 18 to release electrons, the electrons can slave the tube 1 8 It is released in the medium. When a high voltage (i · e · 50 0 0V) is applied to the anode light-emitting plate, the electrons released by the carbon microtubes 18 are subjected to the anode electric field to pass through the porous grid 16 to hit the phosphor. 1 2 to achieve the purpose of emitting light.

Its control is shown in the schematic diagram in Figure 3 below. The L wire 21 in the bottom plate can emit electrons when the corresponding positive line is input, but only when the second metal layer line 31 is also input a positive voltage at the same time. The electron was able to pass through the grid 16 and hit the corresponding phosphor 12 to cause the phosphor 12 to emit light. Because X, y matrix addressing can be driven in a unit at the same time, many red, blue, and green pixels (pixels) can be produced on a light-emitting element.
