8. If there is a chemical formula in this case, it depends on the chemical formula that best shows the characteristics of the invention: IX. Description of the invention: [Technical field of invention] Like money, the structure used for image display and its formation [Previous technology] 】 Electronic display devices have been the tools of the age-old people to transmit information to the sea. It is widely used in televisions, computer terminals, mobile phones, and various fast-moving imaging and processing tools. The well-known display has a light-emitting diode ING_DES hereinafter referred to as Qing's display and includes 200840406 LED OLED EOLEDTING DIODES, plasma display (PLASMA DISPLAYS), LCD LCD (LIQUID CRYSTAL DISPLAYS) and The earliest CRT cathode ray image tube display. In addition to the heavy CRT in the vacuum tube to control the cathode electron beam scanning to the three-color fluorescent spot on the fluorescent screen to develop color; the rest have progressed to the thin-type semiconductor electronic technology with address-controlled color point illuminating color technology 'To achieve the goal of "light and thin, power saving, longevity and low price". The display of colors mainly combines the three primary colors of red (R), green (G) and blue (B) to present colors. It is a method in which humans use scientific methods to recover and reproduce color, and it has been for many years. In particular, when a CRT picture tube is used, the color reproduction is combined with a three-color fine color fluorescent film C0L0RFILTER on the display panel. After decades of display history, this method has also been used in the subsequent development of plasma display, lcd display, field emission display FED (FIELDEMISS surface DISPLAY) and white light 0LED and other imaging technologies. Conventionally, these color displays use the _ three-color point illuminating or penetrating color filter, and the chip RGB three-color dot' to be arranged in a variety of planes juxtaposed to form a 'light color combination and display color. Due to the extremely small spacing of the extremely thin three-color blocks on the color filter, the 14-pin display with a resolution of brain X 768 has a horizontal width of about 286 mm (286 coffee _) and a pixel pitch of 279·. The distance between the color spaces is 93 eggs. According to the human eye, the decomposition force is about ◎. 7 (Μη (the distance between the center of a pair of dark lines and the center) and the distance of the clear vision is 25 cm (25〇〇〇〇_). Interval: 200840406

ΔΙ = 2 X tan(0· 70/60) χ 250000//m = 102/zm Pixel pitch 279· 2 > Μ > The distance between three colors is 93 than the RGB color block spacing 93//in is larger 9μ® 10%, so the human eye can't distinguish the RGB tri-color block and achieve the purpose that the color filter can not be seen. This is why the 1024 χ 768 resolution display only needs 93/xm, which is 9//m less color filter patch spacing than the 1〇2μιη, which is enough to overcome the human eye discrimination ability, not necessarily small enough Causes color filters to be more difficult to manufacture. Since the pixel pitch of 279.2/zm is larger than the human eye discrimination pitch, we can also see the pixel grid on the LCD. Yet another disadvantage is that the human eye can accept the requirement of clear identification when watching a small-sized display fashion, but when the display is gradually enlarged or enlarged at a long distance, the RGB three-color block is gradually amplified to gradually separate the distortion, and high resolution cannot be achieved. Degree pixel rendering requirements. Manufacturing techniques such as conventional semiconductor light sources, organic semiconductor light sources, and liquid crystal LCD controlled light output semiconductors are all required for stacking on a flat substrate by layer-by-layer deposition, epitaxy, evaporation, or diffusion printing. The material is powered by the bottommost electrode and the uppermost electrode to achieve the purpose of illuminating the upper luminescent layer upwards (or downwards) or penetrating light (such as an LCD). It can be seen from the prior art that the upward (or downward) illuminating light source structure, the upper (or lower) opaque power supply electrode 1 占用 1 occupies the light exit port, and blocks the light emitted by the intermediate light-emitting layer, thereby reducing The original luminous efficiency and the consumption of unnecessary power, as shown in Fig. 1, are illustrated as a double-isolated light-emitting diode. For the light exit electrode, 102 is rHUGaAs, 1〇3 is p-A1GaAs active active layer (ACTIVE LAYER), 104 is p_GaAs substrate, and 1〇5 is bottom layer p ohmic contact 6 200840406 pole. If the brightness of the light is blocked for the light exit electrode, the life of the illuminant is lowered. In order to overcome the problem of light-shielding of the power supply electrode, there has been a technique of using a transparent electrode to increase the output light energy; however, the material of the fully transparent electrode cannot be achieved at present to solve the problem. It is also known that the light source of the upper and lower layer stacking method is such that the light output rate is increased, and the electrode area of the light exiting portion is reduced, and the length of each electronic hole pair which causes the light-emitting function provided by the upper and lower electrodes is different; As a result, the light is emitted sequentially in the interval of the power supply pulse switch, resulting in uneven brightness or inability to concentrate the instantaneous brightness and reduce the bottom reaction speed. Some QLEJs that emit white light and white light to RGB color filters that use LCDs, as in the early CRTs to indirectly synthesize color pixels, have long been subject to color filtering and optical manufacturing. The industry can be controlled by independent technology. Nowadays, active direct-emitting LEDs are very mature. They should get rid of the use of color filters for indirect illuminating to reduce cost and improve resolution, and play the natural advantage of self-illumination direct color rendering. SUMMARY OF THE INVENTION The three shortcomings of the conventional conventional light-emitting diode light source and the conventional color display manufactured by the above prior art are as follows: 1. Indirect color mixing by the three-color block of Cai Xun instead of direct overlap penetration synthesis Color, a method of reproducing a primary color of a pixel, which is not resistant to the display requirements of the enlarged size. 1. The electrodes of the upper and lower power supply modes occupy the light exit port, and the blind defects cannot be completely avoided. 7 200840406 III. The pulse switch interval of the relative position structure defects of the upper and lower power supply electrodes is successively illuminated. The invention has the patent name of "(4) invention patent case number: 095146963": "coaxial optical fiber with refractive index distributed in radius and its _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Coaxial to the county-like structure, plus the direct color development technology of the color layer upright and heavy, which is shared by the _ heart and the core, to solve the above problems at the same time. The coaxial semiconductor light source system is a kind of "electrical vibration" formed by coaxially supplying power to the annular semiconductor layer of the middle illuminating layer. The following two techniques use coaxial power supply to solve the above problems, as follows: Coaxial structure of each color LED is shown in Figure 2, so that the arrangement of the lower layer above the conventional illuminator-electrode electrode becomes the invention. Coaxial arrangement. For example, FIG. 1 is an axis electrode, 2Q2 is a coaxial outer ring electrode, 203 is an annular light-emitting layer, 2〇4 is an annular hole injection or conduction layer, and 205 is a ring-shaped electron injection or conduction layer, 2〇 6 is a light-transmissive insulating layer, and the second-order is a base plate. Then, the current is supplied from the anode 2〇1 of the shaft center, and is equally distributed in the radial direction to the outer ring conductor 2〇2, and the light of the electrode 1〇1 contact and the guide wire above the light outlet of the conventional coffee is removed. The light emission rate can be increased by emitting a resistance. What's more important is that all the electronic holes that provide illumination are arranged by the equidistant distribution of the coaxial, and the light is emitted at the same time in the power supply pulse switch interval. Not only the brightness is concentrated to increase the luminous efficiency to save power, and there is no delay illuminating drop to improve the display reaction. Speed 1 solves the problem 2 and the problem. The axis of the three-color light-emitting diode that is coaxialized is shared by the light-emitting diode shown in Fig. 3 (hereinafter referred to as coaxial color light-emitting diode CQJJ). A COAXIAL COLOR LIGHT brain TTING DIODES), for example, 3〇1 is a three-color axis shared electrode, 302 is a red R layer, 3()3 is a green G layer, 304 is a blue B layer, and 305 is a red R coaxial outer ring power supply. Electrode, 3 volumes are green G coaxial outer ring power supply electrodes, 307 is blue b coaxial outer ring power supply electrode, 308 is base plate, 309 is transparent insulation layer, no is transparent insulation layer, 311 is transparent insulation layer, 312 is ring shape The light-emitting layer, 313 is an annular hole injection or conductive layer, and 314 is a ring-shaped electron injection or conductive layer. Then, the conventional flat color display is arranged in a planar three-color block arrangement, and becomes a three-color layer to be arranged in a vertically vertical overlapping co-construction. The display composed of all CCLEDs can improve the resolution by three times. The coaxial RGB three-color layer (302 is a red R layer, 303 is a green G layer, and 304 is a blue B layer) can directly color upwards with a minimum number of layers, and the three colors are concentrated in the same pixel area and are presented in primary colors. Get rid of the use of color filters to avoid indirect illuminating. Since the three colors are erect, the amplification will not separate the three colors to produce a distortion problem. The coaxial shared electrode 301 is changed to the light-transmitting IT0 electrode, and the power supply 200840406 has the function of deriving and mixing the underlying light, so that there is no dark spot in the center of the single pixel - solving the problem 2. The details are as follows: After the respective color LEDs are coaxially structured, the conventional LED electrodes are arranged from the upper and lower layers to be coaxial, and the current is supplied from the anode 2Q1 of the shaft and radiated by the radius. Equidistant diffusion to the outer ring conductor 2〇2, as shown in the top view of one of the LEDs in Figure 4. A light-emitting diode system converts electrical energy into a semiconductor component of light energy. Therefore, the injection of current is required, and in particular, how to uniformly diffuse the injection current throughout the light-emitting diode is extremely important. According to the illustration, the hole and the electron pair generate natural light (Sp0NTANE0US EMISSION) in the ring-shaped light-emitting layer 203 due to different light-emitting mechanisms (such as HOPING · EXCITING.··) driven by the electric field of the coaxial power supply electrodes. Four-way shot. Due to the formation of the coaxially powered two electrodes, the electrons 4Q4 and the holes 403 provided by the two electrodes flow to the circular light-emitting layer 203' sandwiched therebetween to move in the closest distance direction, which is also the direction of the electric field polarization of each radius. That is, in the action of forming the maximum radial electric field, the carrier moves in the direction of the maximum radial electric field. The thickness of each ring layer of the concentric semiconductor centered on the axial electrode of the present invention is uniform, and the electron or the hole is uniformly diffused along the radius to the outer ring electrode and combined to emit light in the light emitting layer. This picture is for the cross section. Because the electrodes are not connected to the power supply mode of the unequal distance distribution of the LEDs as shown in Fig. 1, the uneven distance 10 as shown in Fig. 5 200840406 is evenly distributed; instead, the power supply mode is _ equidistant power supply, so that the power supply pulse switch In the interval, the light provided by the two (10) electrodes is used as the _length_, which means that the mail is carried out and the buckle is traveled to the luminescent layer to combine the illuminating. It is in the power supply pulse off zone _ can be instantaneous brightness and rapid development response. The hair is completely accustomed to the ^ optical port above the electrode contact and the guide wire light (four) series whistle (four) wire. Although the conventional structure has the use of upper and lower transparency of the IT0 yin and yang electrodes (such as the secret 10% Sn 〇 2, the penetration rate of 81%); but its light transmittance is not 100%, indicating that it also blocks 10~20% ' This is hardly worthwhile for efforts to increase the quantum efficiency of luminescent materials by ~20%. The coaxial semiconductor light source of the present invention has the function of not being shielded by the wire after the three-color coaxial co-construction without the arrangement of the upper electrodes. The axes of the coaxial three-color light-emitting diodes are shared and coaxially co-constructed to increase the pixel density (or resolution) and can be directly joined to color at the same pixel block position. The three-color coaxial structured LED diode of the concentric arrangement after the concentric arrangement of the coaxial core, as described above, can simultaneously emit color according to the content of the signal when the RQg three-color sync signal pulse arrives at the same time. According to the principle of display manufacturing, each CCLED can be composed of a color display. Color displays are mainly based on display color pixels, and their ability to display color pixels has many representations. As an example of a commonly used screen display resolution, a conventional 1024 X 768 resolution color display, 11 200840406, has 1024 color pixels in its horizontal direction and 768 color pixels in the vertical direction. In actual production, because a peach pixel is arranged by a red LED, a green light, and a blue light LED, the three positions are arranged. · Display _ horizontal direction is indeed made of brain X 3 = 3072 LED monochrome position block. When the color pixel unit CCLED of the three-color UD _ co-constructed by the _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Upright reunion display 'Let the horizontal direction 3 to be a monochrome position block can be changed to 3072 upright depth direction of the color pixel block, the vertical view of the 7 view 2304 monochrome position block can be changed to 2 erect Color pixel blocks in the depth direction. If the CCLEDs are arranged to have a diameter of 9 〇 eggs and the ca ribs are arranged at a distance of 3//m from the CCLED, then the coaxial semiconductor of the coaxial coaxial display of the present invention can be triple-resolutiond and become 3072. X 2304 color pixels, the spacing (10) is also in line with the requirements of the human eye identification Μ - (10) Qing. Therefore, not only the resolution can be improved, but also any multiple magnification display can be performed without color separation, that is, the disadvantage of generating a three-color block separation after amplification. The method for directly synthesizing the color of the coaxial color illuminator of the present invention and the pro-luminescence of the stacking method of the University of Princeton are direct color development, and the method has been performed by the University of Princeton in 1998 (The Trustees 〇f 12 200840406

Forrest et al. of Princeton University proposed and patented us 5,707,745 "Multicolor organic light emitting devices", as shown in Figure 6. Since this method (multilayer stacking method) stacks RGB organic semiconductor light-emitting elements, it can be used in one The pixel element emits a primary color or a synthetic white light. The disadvantage is that when the three colors are vertically overlapped, the number of layers in the light-emitting direction is increased, the relative difficulty in controlling the process is increased, and the underlying light must pass through a sufficient number of layers. It is necessary to increase the power to increase the brightness, resulting in a decrease in the reliability of the display. The difference between the present invention and the invention is that the RGB three-color annular light-emitting layer of the present invention overlaps immediately above and below, wherein only one layer of the fully transparent oxidized broken insulating layers 309 and 310 is separated. This not only directly illuminates the color in the light-emitting direction with a minimum number of layers, but also simplifies the circuit with low power, and there is no conventional three-layer non-transparent electrode to block the loss of transparency of the rain. In the present invention, the two electrodes of the three-color coaxial power supply are respectively formed. Electrons in a circular semiconductor light-emitting layer (or airborne layer) sandwiched between two electrodes The hole flow and the generated excitation photon can complete the synthetic light emission through the arrangement of various waveguide reflection or refraction paths when manufacturing each component. 3. The coaxial shared electrode is replaced by the transparent IT0 electrode. Use the low resistivity of ΠΌ (can be about 200 " Ω · cm below the conductor) and the high refractive index 0 relative to the surrounding lower refractive index material to concentrate the light), in the circular luminescent layer (Ν_ί€ =1·7) and its insulated 13-light glass (N fine = 1.45) interface, less than the critical angle of 5 > c = sin" (Nglass / N°rganic) = 58·5. All of the light in the LIGHT ESCAPE CONE can be directed upwards; the rest is greater than the critical angle of 58.5. The light that is totally reflected by the total reflection into the light-emitting layer can also be used to derive the light in the internal structure of the coaxial light-emitting diode in the following two ways: (1) A transparent axis having a higher refractive index is used. Since the higher refractive index than the surrounding material will cause the incoming light to be totally reflected and not easily emitted, the axial electrode will be easily led out like a light collecting column, and the direct and indirect color mixing will be achieved and the center of each pixel will be eliminated. The function of the dark spot exists, as shown in FIG. 7A, for example, 701 is a blue light emitting diode layer, 702 is a green light emitting diode layer, 703 is a red light emitting diode layer, 704 is a red bottom layer light, and 705 is green. The bottom layer reflects the light, and the 706 emits light to the blue surface. The coaxial light-emitting diode in the figure is an example of a coaxial OLED structure, the axial electrode has a higher refractive index (CKo), the refractive index of the circular light-emitting layer (N_nic: rl. 7) and the upper and lower insulating transparent glass (N glass) ~ 1· 45) The light guide arrangement 'is known that the shaft electrode has led out the light inside and inside the bottom. (1) Using the intrinsic light reflection inside the coaxial structure and the circular circle as the lens concentrating interaction, and utilizing the characteristics of the reflected light of the outer ring metal electrode surface 707, such as silver plating, to increase the reflectivity of 200840406 and Concentrating power of concave mirrors. Then, the light that is not reflected by the total reflection of the LIGHT ESCAPE CONE of the coaxial color light emitting diode 708 can be easily derived, as shown in FIG. 7B. The light is projected in the collecting cylinder by using the display of the transparent common coaxial core structure of the photoelectric coupling. At the center of the common electrode axis IT〇, a light-transmitting column for guiding light and synthesizing the pixel is formed, which is advantageous for the brightness and color of the light spot. To sum up, the present invention can solve the above problems of the conventional LED and its application on the display after repositioning the coaxial power supply diode electrode structure, and achieve the following objectives: 1. The coaxial light-emitting diode has improved luminous efficiency. The three-color coaxial shared co-construction, the resolution of the color display composed of the three colors is increased by three times, and the display enlarged with size is never affected by the separation of the three-color block distortion. _ —, no 1:1 electrode line blocking, the light source becomes larger to improve the brightness of the light. Third, the ride will turn the record to turn the heart to make the silk core brighter. 4. Direct illumination eliminates the complexity of using color filters synthesized by three-color regions and reduces costs. Direct illumination will make the color more vivid and saturated. 5. The coaxial equidistant power supply electrode makes the instantaneous brightness of the light-emitting diode concentrated, and can improve the apparent reaction speed to make the quality better.
