BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a light-emitting element, and more particularly to an electron-emitting light-emitting element and its use. [Prior Art] Currently, two types of light-emitting structures are mainly used in mass-produced light source devices or display devices, including: 1. Gas discharge light source: applied to, for example, a plasma panel or a gas discharge lamp, mainly using a cathode and an anode. The electric field causes the gas filled in the discharge chamber to be freed by a glow discharge to cause the electrons to collide with the gas to generate a transition and emit ultraviolet light. The fluorescent layer also located in the discharge chamber absorbs the ultraviolet light and then emits Visible light. 2. Field emission light source: applied to, for example, a carbon nanotube field emission display, mainly for providing an environment in which a vacuum is applied, and an electron emitter (nectr〇n emitter) of a nano carbon material is formed on the cathode to The use of a high aspect ratio microstructure in the electron-emitting end helps the electrons overcome the work function of the cathode (work fUncti〇n) and leave the cathode. Further, a phosphor layer is coated on an anode made of indium tin oxide (ITO) to cause electrons to escape from the Chen and N carbon nanotubes by a high electric field between the cathode and the anode. In this way, the electrons can "expose the phosphor layer on the anode in a vacuum environment to emit visible light. ^, the above two kinds of light-emitting structures have their disadvantages. In the example, the wire is shot after the shot, for the sake of Due to the special requirements of the material selection in the source discharge light 1353618 P55950076TWC4 22306-4twf.d〇c/n. In addition, the optical mechanism undergoes two processes before it happens to reduce the discharge, if it is difficult to The electron emission is generated when the loss is large, and the electron emission end of the cathode is grown or coated. The technology of the sub-class cathode structure is not mature, and the uniformity and production of the electron-emitting end are encountered. Poor rate _. In addition, the distance between the cathode of the light source and the 13⁄4 pole needs to control the wealth, ^

Difficulties also increase the cost of production. BACKGROUND OF THE INVENTION 1.

Further, the present invention relates to a display device which uses the above-described electron-emitting light-emitting element as a display element for providing a good display product H, which can reduce the cost and complexity in production.

To specifically describe the contents of the present invention, it is proposed herein that the halogen structure of the device comprises a first substrate and a second substrate. A plurality of cathode structure layers are on the first substrate. The second substrate is a light penetrating material. A plurality of anode structure layers are on the second substrate, wherein the anode structure is a light penetrating conductive material.

A partition structure is disposed between the first substrate and the second substrate, and the anode structure layers are respectively separated from the cathode two-layer layers to form a plurality of spaces. A plurality of phosphor layers are respectively located between the anode structure layers and some cathode structure layers. - The low pressure gas fills the spaces separately. The low pressure gas layer has an electron mean free path that allows at least 6 1353618 P55950076TWC4 22306-4twf.doc/n a sufficient number of electrons to directly strike the phosphor layer at the operating voltage. In addition, the present invention proposes a face-up device having a plurality of P-array arrays, the surface of which exhibits a halogen-containing light-emitting element, and the electron-emitting light-emitting element includes a cathode structure layer; An anode structure layer; a phosphor layer is disposed between the cathode structure layer and the anode structure layer and a low pressure gas disposed between the pole and the anode for inducing the cathode to uniformly emit a plurality of electrons. The low-pressure gas has an electron average from (four) diameter 'allowing at least a sufficient amount of electrons to directly hit the phosphor layer under the operation. The invention also proposes a display device comprising a -th substrate and a second substrate. A plurality of cathode structure layers are located on the first substrate i to form a two-dimensional array. The second substrate is a light penetrating material. a plurality of anode structure layers are disposed on the second substrate, wherein the anode structure layers are light transmissive conductive materials, wherein the first substrate and the second substrate are opposite each other, and the cathode structure layers are The anode structure layers are aligned separately. A partition structure is located between the first substrate and the second substrate. The anode structure layer and the cathode structure layer are respectively separated from each other to form a plurality of spaces. A plurality of phosphor layers are respectively located between the anode structure layers and the cathode structure layers. A low pressure gas is separately filled into the spaces, wherein the low pressure gas layer has an electron mean free path that allows at least a sufficient number of electrons to directly strike the camping layer at the operating voltage. A plurality of driving units are disposed on the first substrate and the second substrate. The plurality of driving units are configured to control the two elements of the two-dimensional array to apply the corresponding operating voltage to generate a luminance gray scale. 7 1353618 P55950076TWC4 22306-4twf.doc/n Based on the above, the present invention utilizes a thin gas to easily conduct electrons from the cathode, thereby avoiding the problem that the electron-emitting end can be formed on the cathode. In addition, since the thin gas is used, the average free path of the electrons is large, and a large amount of electrons can directly react with the fluorescent layer to emit light before hitting the gas, and the process is not Glow discharge will occur. In other words, the electron-emitting light-emitting device of the present invention has higher luminous efficiency, is easy to manufacture, and has better production yield. The above and other objects, features and advantages of the present invention are more apparent.

It will be understood that the preferred embodiments are described below in detail with reference to the accompanying drawings. D. Embodiments The electron-emitting type light-emitting element proposed by the present invention has the advantages of a conventional gas discharge source and a field emission source, and overcomes the disadvantages of the two conventional light-emitting structures. Please refer to the comparison diagram of the above two conventional light-emitting two-frames and the light-emitting mechanism of the electron-emitting light-emitting element of the present invention. In more detail, the conventional gas glow discharge source utilizes an electric field between the cathode and the anode to free the gas filled in the discharge chamber, and the gas guides the electrons to smash the H to produce a purple material. (4) Light Layer suction = iii visible light after ultraviolet light. In addition, the known field emission system is in an ultra-high vacuum environment t, which helps the electrons to overcome the cathode's work function against the cathode by the high aspect ratio structure of the electron-emitting end on the cathode. Thereafter, the electron material escapes from the electron-emitting end of the cathode by a high electric field between the cathode and the anode, and strikes the f-light layer on the anode to emit visible light. That is to say, the materials of the glory layer 8 1353618 P55950076TWC4 22306-4twf.doc/n can be made of materials capable of emitting visible light infrared light or ultraviolet light according to the design mechanism. And the above-mentioned known illuminating mechanism is not _ _, the present _ electron-emitting illuminating element does not need to form an electron-emitting end, but uses a thin gas to easily lead electrons from the cathode, and allows the electron to directly react with the light layer . • Compared with the conventional gas glow discharge source, the amount of gas filled in the electron-emitting light-emitting device of the present invention only needs to be able to derive electrons from the cathode to generate a glow discharge, and does not utilize the purple bud. Light illuminates the glory layer and produces light' so there is no need to worry about the attenuation of the material inside the component being exposed to ultraviolet light. It has been experimentally and theoretically verified that the gas in the electron-emitting light-emitting device of the present invention is relatively thin, so that the average free path of electrons can be about 5 mm or more. In other words, most of the electrons hit the fluorescent layer directly before the molecules that hit the gas, and emit light. Further, the electron-emitting type light-emitting element of the present invention does not need to pass through the process to generate light, so that the light-emitting efficiency is high and the energy loss can be reduced. On the other hand, compared with the conventional field emission light source, it is necessary to form a microstructure as an electron-emitting end on the cathode, which is difficult to control in a large-area process. The most commonly used microstructure is a carbon nanotube (the (10) nanotube). On the coating of the cathode, there are problems of the length and length of the carbon tube, so that the light-emitting surface has dark spots and uniformity of illumination. Poorness has always been a technical bottleneck and cost source for field emission sources. The electron-emitting light-emitting element of the present invention can uniformly conduct electrons from the cathode by gas, and requires a light-emitting sentence of the π-electron emission type light-emitting panel to reach 75/. . The extent of the solution is a bottleneck that is difficult to improve. Therefore, it is possible to save a lot of money and the process is relatively simple. Further, the electron of the present invention;

= The part is filled with a rare gas, so there is no need for an ultra-high vacuum environment, which avoids the _ encountered when the lamp is over-vacuum. In addition, it has been experimentally known that the electron-emitting illuminating element of the present invention can reduce the starting electric dust (about turn) to about 〇 叫, which is much lower than the general field emission light source by the help of gas. The starting voltage value of 3ν/μηι. Furthermore, according to the known Child-Langmuir equation, the actual correlation data of the electron-emitting light-emitting element of the present invention can be calculated by hand, and it can be concluded that the cathode dark region distribution range of the f-sub-emissive light-emitting device of the present invention is about 10 Between ~25 cm (cm), much larger than the distance between the anode and the cathode. In other words, there is almost no gas in the electropolymerization state between the anode and the cathode, and therefore it is possible to confirm that the electron-emitting light-emitting element of the present invention is not a mechanism

Instead of illuminating, the electrons of the cathode are derived by means of gas conduction, and then the electrons directly act on the phosphor layer to emit light. Referring to Fig. 2, there is shown the basic structure of the electron-emitting light-emitting device of the present invention. As shown in FIG. 2, the electron-emitting light-emitting element 2A mainly includes an anode 210, a cathode 220, a gas 230, and a phosphor layer 24, wherein the gas 230 is located between the anode 210 and the cathode 220, and the gas 23() is subjected to an electric field. After the action, an appropriate amount of positively charged ions 2〇4 is generated to induce the cathode 22 to emit a plurality of electrons 202. It is worth noting that the atmosphere of the gas of the present invention is in the environment of 8xl 〇-i tor (to 1 〇 -3 tor (t〇rr), 1353618 P55950076TWC4 22306-4twf.doc/n Preferably, the pressure is, for example, between 2xUT2 torr (torr) to ΙΟ3 tor (torr) or 2 parent 1〇-2 tor (cut) to 1.5乂1〇-1 tor (cut 1 In addition, the phosphor layer 240 is disposed on the moving path of the electrons 202 to emit light L with the electrons 202. In the present embodiment, the phosphor layer 240 is coated on the surface of the anode 210, for example. In addition, the anode 210 is, for example, a transparent conductive oxide.

(Transparent Conductive Oxide, TCO) is formed to emit light L through the anode 210 to emit the electron-emitting light-emitting element 200, wherein an optional transparent conductive oxide such as indium tin oxide (?), fluorine-doped oxidation Common materials such as tin (FTO) or indium zinc oxide (ΙΖ0). Of course, in other embodiments, the anode 210 or the cathode 220 may also be made of metal or other material having good electrical conductivity. The gas 230 used in the present invention may be an inert gas such as nitrogen (Ν2), helium (He), neon (Ne), argon (Ar), gas (Kr), xenon (Xe), or hydrogen (3⁄4), carbon dioxide. (C〇2) A gas having good electrical conductivity after dissociation, or a general gas such as oxygen (〇2) or air (Air). Further, by selecting the kind ' of the fluorescent layer 240', the electron-emitting light-emitting element 2 can emit different types of light such as visible light, infrared rays or ultraviolet rays. In addition to the embodiment illustrated in Fig. 2, in order to improve the luminous efficiency, the present invention can form a material which is easy to generate electrons on the cathode to provide an additional electron source. The electron-emitting light-emitting element 300' of another embodiment of the present invention as shown in Fig. 3 has, for example, a secondary electron source material layer 322 formed on the cathode 320 thereof. The material of the secondary electron source material layer 322 may be magnesium oxide (MgO), three 1353618 P55950076TWC4 22306-4twf.doc/n oxidized divalent (Tb203), antimony trioxide (La2〇3) or ceria (Ce 〇 2). Since the conductive gas 330 generates free ions 3〇4, and the ions 3〇4 are positively charged, they move away from the anode 310 toward the cathode 32〇, so when the ions 304 strike the secondary electron source material layer 322 on the cathode 320. , an additional secondary electron 302' can be generated. More electrons (including the original electron 302 and secondary electrons 302) interact with the phosphor layer 34 to help increase the light-emitting efficiency. It is worth noting that this secondary electron source material layer 322 not only helps to generate secondary electrons, but also protects the cathode 32 from excessive bombardment by the ions 3〇4. Furthermore, the present invention may alternatively form a structure similar to one of the anode or the cathode or the electron-emitting end of the field-emitting source on the anode and the cathode to lower the operating voltage on the electrode and to generate electrons more easily. 4A-4C are respectively a plurality of electron-emitting type light-emitting elements having an induced discharge structure of the present invention, wherein like members are denoted by the same reference numerals, and the description thereof will not be repeated. As shown in FIG. 4A, an evoked discharge structure 452 is formed on the cathode 42 of the electron-emitting light-emitting element 4A, which is, for example, a metal material, a carbon nanotube, or a carbon wall. Microstructure composed of nanowau), carbon nanoporous, columnar zinc oxide (Zn〇), oxidized (ZnO) material, etc. Further, the induced discharge structure 452 can be combined to increase the aforementioned second Electron source material layer. Further, gas 430 is located between anode 410 and cathode 420, and phosphor layer 440 is disposed on the surface of anode 410. The electrons 402 are more easily generated by inducing the discharge structure 452 to reduce the operating voltage between the anode 410 and the cathode 420. The electron 402 and the fluorescent layer 12 1353618 P55950076TWC4 22306-4twf.doc/n 440 can generate light L. The electron-emitting light-emitting element 400b illustrated in FIG. 4B is similar to that illustrated in FIG. 4A. The more obvious difference is that the induced discharge structure 454 is disposed on the anode 410, and the induced discharge structure 454 is as described above. It is a metal material, a carbon nanotube, a carbon nanowall, a carb〇n nanoporous, a columnar zinc oxide (ZnO), or a zinc oxide (ZnO) material. The microstructure of the structure. Further, the induced discharge structure 452 may be combined with the addition of the aforementioned secondary electron source material layer. Further, the phosphor layer 440 is disposed on the induced discharge structure 454. 4C illustrates an electron-emitting light-emitting element 400c having both induced discharge structures 454 and 452, wherein the induced discharge structure 454 is disposed on the anode 410. The phosphor layer 440 is disposed on the induced discharge structure 454 to induce a discharge structure. 452 is disposed on the cathode 420. Gas 430 is located between anode 410 and cathode 420. The above-mentioned plurality of electron-emitting light-emitting elements 400a, 400b or 400c having induced discharge structures 452 and/or 454 can further integrate the design of the secondary electron source material layer 322 as shown in FIG. 3, and form a shape on the cathode 420. In the secondary electron source material layer, if the induced discharge structure 454 has been formed on the cathode 420, the secondary electron source material layer may be covered with the induced discharge structure 454. Thus, not only the operating voltage between the anode 410 and the cathode 420 can be lowered, but the generation of the electrons 402 can be made easier, and the number of electrons 402 can be increased by the secondary electron source material layer to improve the luminous efficiency. The electron-emitting light-emitting element proposed by the present invention may have different types as the light-emitting structure. 5 to FIG. 6 respectively show light-emitting structures of several different shapes of an electron-emitting type light-emitting element to which the present invention 13 P55950076TWC4 22306-4twf.doc/n is applied. FIG. 5 shows another horizontal emission type (ΐη_ρΐ&η6) The emission structure 600' of the emission is mainly to arrange the anode 61 〇, the cathode 62 〇 and the phosphor layer 640 on a substrate 68 ' 'this substrate 68 〇 is, for example, a glass substrate ′ and the anode 610 and the cathode 62 〇 The material is made of a common transparent conductive oxide such as metal, indium tin oxide or indium zinc oxide or other material having good conductivity. The phosphor layer 640 is located between the anode 610 and the cathode 620 'by gas 630 The induced electrons 602 will pass through the phosphor layer 640 to emit light L. The gas pressure of the environment in which the gas 630 of the present invention is present may be between 8χ1〇-ι (9) and 1〇_ 3 Tor (t〇rr) 'better' this pressure is between 2xl0_2 tor (torr) to 1〇-3 tor (tory) and ΐ.5χΐ〇1 tor (t〇rr). The actual gas pressure and operating voltage will vary depending on the anode-anode distance, gas type and structure. In addition, the gas 630 used in the present invention may be an inert gas such as & (nitrogen), helium (He), neon (Ne), argon (Ar), chaos (Kr), xenon (Xe), or hydrogen ( η〗), carbon dioxide (c〇2), etc., which have good electrical conductivity after dissociation, or oxygen (10), air (Air), etc. Further, by selecting the type of the phosphor layer 64, it is possible to cause the light and the structure 600 to emit different types of light such as visible light, infrared light or ultraviolet light. How to maintain a closed gas environment can be achieved, for example, by general techniques, the details of which are not described in detail herein. For the description of other components, please refer to the above implementation and repeat them. It should be noted that the above-mentioned light-emitting structure of FIG. 5 is only used as an example, and 'four' is not used to define the light-emitting structure of the present. In other 1353618 P55950076TWC4 22306-4twf.doc/n embodiments, the above-described light emitting structure may be combined with the secondary electron source material layer 322 of FIG. 3 or the induced discharge structures 452 and 454 of 4A to 4C, for example, according to different considerations. 'To meet different needs. The electron-emitting light-emitting device of the present invention can be further used to fabricate a light source device, which is composed, for example, of any of the foregoing embodiments, to provide a light source. FIG. 6 illustrates a light source device in accordance with an embodiment of the present invention. As shown in Fig. 6, the light source device 8A includes a plurality of electron-emitting light-emitting elements 8a arranged in an array to provide a light source s. The design of the electron-emitting light-emitting element 8〇〇a selected for the present embodiment includes, for example, any of the foregoing various embodiments. For example, the light source device 800 can adopt a design similar to the light-emitting structure 600 of FIG. 5, and a plurality of sets of the anode 81 〇, the cathode 82 〇, and the fluorescent layer 840 are formed on a substrate 880 for the purpose of large-scale. Of course, the various electron-emitting light-emitting elements proposed above can also be applied to display devices. Figure 7 is a diagram showing a display device in accordance with an embodiment of the present invention. As shown in FIG. 7, each display element 902 of the display device 9 is composed of an electron-emitting light-emitting element to form a display frame by a plurality of display elements 902, displaying static or dynamic 昼. surface. Since the electron-emitting type light-emitting element is used as the display element 9〇2, for example, a fluorescent layer capable of emitting red light, green light, and blue light is used in the electron-emitting light-emitting element to form a red display pixel scale and a green display. The alizarin G and the blue color do not show the prime B, and the full color display effect is achieved. In addition, as shown in Fig. 8, the arrangement of the pixel arrays of red, green and blue light of another display device 900' may be determined according to the actual design to achieve color gray scale display. In addition, according to the design requirements of 15 1353618 P55950076TWC4 22306-4twf.doc/n, it can also add one color light, such as the color of the light (检range, 〇) light, combined with red, green and blue sputum, to form a The structure of the unit. FIG. 9 is a diagram showing a pixel structure of a display device according to an embodiment of the present invention. Referring to Figure 9, in general, the colors are three primary colors of red, green, and blue, which are achieved in accordance with the relative brightness gray scale. The embodiment is illustrated by taking three pixels of red, green and blue as examples. Designed using the aforementioned techniques, the pixel structure may include, for example, a first substrate 1000 and a second substrate 1〇〇2. A plurality of cathode structure layers 1 〇〇 4 are located on the first substrate 1000. The second substrate 1002 is a light transmissive material. A plurality of anode structure layers 1010 are disposed on the second substrate 1002, wherein the anode structure 1010 is a light transmissive conductive material. The first substrate 1000 and the second substrate 1〇〇2 face each other, and the cathode structure layer 1004 and the anode structure layer 1〇1 are respectively aligned. A partition structure 1012 is located between the first substrate 1 〇〇〇 and the second substrate 1 〇〇 2, and respectively separates the anode structure layer 1010 from the cathode structure layer 1 〇〇 4 to constitute a plurality of spaces. The plurality of phosphor layers 10a, 1008b, and i8c are located between the anode structure layer 1010 and the cathode structure layer 1004. A low pressure gas 1006 fills in those spaces, respectively. The low pressure gas 1〇〇6 has an electron mean free path that allows at least a sufficient amount of electrons to directly strike the phosphor layers l8a, 1008b, 1008c at an operating voltage. Here, the phosphor layer 1008a, the phosphor layer 1008b, and the phosphor layer i008c are, for example, different materials, and are excited to emit red light, green light, and blue light. As for the gas pressure values of the respective halogen gases, they may all be the same or different, which are design and actual operation changes. Of course, if the display only requires a single color display, the material configuration of the phosphor layer can also be 1353618 P55950076TWC4 22306-4twf.doc/n different arrangements. Figure 10 is a diagram showing the structure of a pixel device of a display device in accordance with another embodiment of the present invention. Referring to Fig. 10, for example, using the design principles of Fig. 6, the configuration of Fig. 9 is used to achieve the design of the display device, but is not the only option. In the display device of Fig. 9, the two electrode structures 1〇〇4, 1〇1〇 are different from the lower substrate 1000 and the upper substrate 1〇〇2, respectively. In Fig. 1A, the two electrode structures 1004', 1010' and the phosphor layers 1?8a, 1008b', 1008c' between the electrodes are on the same side, for example, on the substrate 1?. The substrate 1 〇〇〇 has a function of light reflection, for example. Depending on the choice of fluorescent material, visible light of different colors can be emitted to produce the desired mixed color. Since the image needs to be displayed using the change in luminance grayscale. The required color is determined by the relative luminance gray scale of red, green, and blue light. Therefore, the gray level of each element requires some mechanism to adjust. The figure is illustrated as a luminance gray scale control mechanism in accordance with an embodiment of the present invention. Referring to Figure U, depending on the gas pressure and the applied voltage, different reactive currents are generated. In general, the current is approximately linear with the applied voltage in terms of the gas pressure of 2xl0_2torr. In addition, the starting voltage will also vary depending on the air pressure. Referring also to 12, the magnitude of the applied voltage also means the amount of electrons striking the camping layer and the energy of the impact. The luminance per unit area is also substantially linear with the applied voltage, and the gray scale value can be changed by changing the applied voltage to combine the desired colors. Based on the gas-based reaction, the relationship between the actual applied voltage and the gray scale can be obtained for the selected gas pressure value as a gray scale correction data. For example, the red, green and blue elements of FIG. 9 or FIG. 10 are used as a single element 17 1353618 P55950076TWC4 22306-4twf.doc/n, and the voltage corresponding to the gray level can be driven by the driver. Referring to Fig. 13, display device 1300 is based on a two-dimensional array of driving methods including a plurality of drivers 1302, 1306 on respective substrates for controlling the anode and cathode structures of the halogen in two directions. The driver 13〇2 has a plurality of control circuits 1304 coupled to, for example, an anode (or cathode) of a plurality of cells of a corresponding row, and the driver 1306 has a plurality of control circuits 1308 coupled to, for example, corresponding rows. The cathode (or anode) of multiple halogens. Control circuit

The intersection of the pixel 131 选择 is selected with the control circuit 1308 to apply a voltage corresponding to the gray value. ^ In the case of a passive driving mechanism, for example, a time division mechanism is used to sequentially display scan lines in a sweep line unit. Since the human eye consists of: seeing the persistence phenomenon, all the scan line components are displayed in sequence for a certain time = image. In this case, since the first-scanning county and the last-scanning line are still two:^', in order to adjust the difference, it is possible to arrange the first-scanning display line to be more ambiguous, and gradually lower the brightness.

The above driving mechanism is adjusted in a passive manner. It can also be driven in an active way. Referring to Fig. 14, the display device is based on the driving mode of the second=, including a plurality of actuators, the anode side in the direction of the anode to control the pixel structure and the negative "mm multiple control circuits such as secret (4) should be For example, t), the driver 14G4 has a plurality of control circuits == a plurality of halogen cathodes (or anodes). By controlling the electric power, the father's other elements are applied to apply the corresponding gray driving mechanism. The element 1406 has a switch control unit 1408 in addition to the electric 1335318 P55950076TWC4 22306-4twf.doc/n. The switch control unit 14〇8 can have, for example, a thin film transistor (TFT) unit, which is controlled by the driver. Turning on or off the halogen, and controlling the brightness of the light.

'Therefore, the reflectance can be increased and the brightness and luminous efficiency can be increased. In addition, the wavelength of light emitted by the electron-emitting light-emitting element depends on the type of the fluorescent layer, and can be designed in different wavelength ranges depending on the light source device or the display device.
