New description: [New technical field] This creation relates to liquid crystal displays, especially to backlight devices used in liquid a displays. [Prior Art] With the trend of computerized home appliances, liquid crystal displays (LCDs) with thin size, high resolution, and low radiation are required to meet the requirements of light weight, thin size, low radiation, etc. Its manufacturing cost has dropped, and it has become the mainstream of the display market in recent years. However, the liquid crystal itself does not emit light, so the LCD must supply light energy such as a backlight by an external light source. The greedy panel is a key component of the liquid crystal display, and the light source with sufficient brightness and uniformity causes the liquid crystal panel to display an image. The backlight board can be roughly classified into a "sidelight type" and a "straight down type" depending on the position of the light source. The direct type design is to set the light source of the light emitting diode (LED) under the liquid crystal panel to make use of the direction of travel of the light beam. The beam is projected onto the diffuser plate below the panel to provide a uniform beam of the liquid crystal panel. Please refer to Figure 10. The existing direct-lit backlight panel illumination mechanism has the following disadvantages: 1. Due to the structural design requirements, the thinning space is small, and the light source is mixed. The average degree of light deteriorates. 2. Use a large number of light-emitting diodes (LEDs). 3 M435621 • The existing backlight panel illumination mechanism is as shown in Figure 1. The program is more annoying and the production cost is high. 4. The light-emitting diode light source (LED) is not fully utilized and is wasted. Based on the shortcomings of the conventional backlight panel, the creator of the present invention proposed a structure in which the optical element is used to generate a dispersed beam, which is reflected by the beam diffuser to the optically diffusing surface, so that the light source can be fully utilized and a uniform planar light source is generated. [New content] One of the purposes of this creation is to provide a backlight structure that can reduce the number of LEDs while reducing the uniformity of light and color, thereby saving energy and saving benefits. A further object of the present invention is to provide a backlight structure that is designed to reduce illumination losses and achieve high light efficiency. Another object of the present invention is to provide a backlight structure that provides for the placement of optical components to achieve a highly simplified thin junction. Another object of the present invention is to provide a backlight structure, a combination of different optical components, and achieve high mechanism stability. The backlight device of the present invention comprises at least a light source array, which is composed of an LED light source and corresponding The optical component fabric is manufactured, and the light source backlight plate is effectively increased by the light source. The ring is illuminated by the light backlight. The light is used to emit light. The light is emitted from the light splitter and split into at least two. A beam diffuser consisting of at least one beam diffusing element reflects or refracts the beam to light! The surface, which is the surface of a miniature optical structure, converts the incident light into a diffuse light in all directions, and the uniform LCD screen illuminates the light. [Embodiment] In order to enable a further understanding and understanding of the features and functions of the shape-constructing device for the purpose of the present invention, the embodiment is described in conjunction with the drawings, and the detailed description is as follows: Please refer to the embodiment of the present invention shown in FIG. 2a. The enlarged schematic diagram is a "direct type liquid crystal display backlight panel" which is composed of a plurality of direct plastic liquid liquids and apparently no backlight structure. For the backlight structure of each direct-type liquid crystal display, please refer to FIG. 2b, which includes: An array of illumination sources E consisting of at least one illumination source 'a beam splitter' that reflects at least two cones of reflective surfaces • ® ( 1 2 1 a, 1 2 1 d) 'transmits the light source The astigmatism is decomposed into at least two beams of light, a beam diffuser consisting of two lenses (122a, 122d) that expands the divergence angle of the two beams of light resolved; and an optical diffusing surface 126 is a micro-optical The surface of the structure converts the beam diffused by the beam diffuser into a uniform liquid crystal screen that diffuses in all directions. The beam of the illumination source splits the beam into at least two beams via the optical splitter. The decomposed pre-beam expands the divergence angle 5 M435621 of the decomposed beam via the beam diffuser, and then forms a uniform liquid crystal illumination through the optical diffusing surface. Light. The optical elements described above can also be combined into a simpler, stronger, and reliable single backlight optical assembly. The details of the backlight structure of the present direct type liquid crystal display are described in more detail below. Hereinafter, various embodiments of a direct-lit type liquid crystal display backlight panel will be described with reference to the drawings. (First direct type liquid crystal display backlight implementation type) The embodiment of the always-on liquid crystal display backlight panel is shown in Fig. 2a. The direct-type liquid crystal display backlight panel is a reflective matrix composed of a plurality of direct-lit type liquid crystal display backlight structures. See Figure 2b for an example of its direct-type liquid crystal display backlight structure. An array of illumination sources E consisting of at least one source. The illumination source array E can conveniently use a light emitting diode (L E D) illumination array or a cold cathode fluorescent lamp (c c F L ) light source. The LED beam is incident light B〇, and the incident light is decomposed into at least two reflected lights B1 1 ' by a cone reflecting surface (1 2丨a, p丨d) composed of at least two reflecting surfaces by a beam splitter. The reflecting surface (丨丨u, 丨nd) reflects the reflected light B 1 1 in the same direction to form a corresponding multi-beam secondary reflected light Β 12» The above-mentioned beam splitter can be a reverse coated with a reflective film: Total reflection surface or optical plane. The secondary reflected light B 1 2 is then enlarged by a beam diffuser composed of at least two lenses (丨 22a, 122d). The lens described above may be a Fresnel or a full phase optical element. The diffused beam after the beam diffuser is spatially discontinuous, for which M435621 ... for this purpose, the optical diffusing surface 126 is added to form a uniform, bright, bright. (Second type of liquid crystal display backlight implementation) The embodiment of the four-beam reflective cone splitter for the always-on liquid crystal display backlight is shown in section 2c. The plane 201 splits the incident light into four beams, and the four reflected surfaces reflect the reflected light in the same direction to form a corresponding multi-beam. The above spectroscope may be a reflective surface coated with a reflective film, and an all-optical plane. The divergence angle is enlarged by the beam diffuser composed of four d (2〇〇a, 2〇〇b_" 200d). The beam diffuser described above may also be a lens phenanthrene optical element. (Second type of liquid crystal display backlight implementation) The direct-lit type liquid crystal display backlight structure can also be a reflection circle (Fig. 2d). The cone reflecting surface 3 turns the incident light into a circle. The subsequent conical reflecting surface 3〇1 reflects the reflected light in the direction to form a corresponding conical light. The beam diffuser that reflects the light twice and then diverges the angle of the incident beam via a beam diffuser consisting of 3〇2 can also be a ring lens, or a corresponding ring-type phenanthrene optical element. The diffused beam after the beam diffuser is vacant, so for this purpose, the optical diffusing surface is added to form a uniform 'continuous illuminating cone consisting of a cone 1 10 which will be the last reflective or b-lens beam. For mirror or cone, please refer to the cone light. The same square ring lens is large. The above 〉 otoscope or room is not connected to the bright 7 M435621 continuous illumination. (Fourth Direct Type Liquid Crystal Display Backlight Embodiment) The above illumination source array, beam splitter, and beam diffuser are all separate elements. Our optical functions can be combined into a simpler, more robust 'reliable single element. For the implementation example, please refer to FIG. 3 a. The direct-type liquid crystal display backlight composed of a plurality of single-element direct-type liquid crystal display backlight structures may be a conical surface matrix. The splitter and beam diffuser of the direct-lit type liquid crystal display backlight structure are combined into a single background optical optical assembly. See Figure 3b for a case study. It is a transparent optical plate. It may be surrounded by a reflective surface coated with a reflective film, an optical curved surface having optical focusing or diverging, a total reflecting surface, and an optical plane. The LEd beam is a beam splitter for the incident light B0' by a combined cone-shaped reflecting surface ("3 1 a, 1 3 1 d" composed of at least two reflecting surfaces of the background optical optical assembly 4". B 0 is divided into at least two reflected lights bn, and a subsequent combined reflecting surface (丨 32a, 132d) facing the reflecting surface is formed to reflect the reflected light in the same direction to form a corresponding multi-beam secondary reflected light B12. The secondary reflected light B12 is emitted through the exit surfaces (133a, 133d) of the background optical optical assembly 400. The exit surface can be a toroidal lens, an optical plane, a corresponding ring-shaped Fresnel or a full-phase optical component. The beam is discontinuous in space, so for this purpose, an optical diffusing surface is added to form a uniform, bright continuous illumination. (Fifth type of liquid crystal display backlight panel implementation) M435621 • For the implementation of the cone-shaped background optical assembly using a four-reflection surface for the all-in-one type LCD backlight, see section 3c. The four-sided conical reflecting surface (211a, 211b...2lid) composed of four reflecting surfaces decomposes the incident light into four beams, and the four subsequent reflecting surfaces (130a, 130b...130d) reflect the reflected light in the same direction. Forming a corresponding multi-beam secondary reflected light. The diffracted angle of the incident light beam is expanded by the secondary reflection light and then passing through the optical lenses (210a, 210b ... 210d) of the exit surface. • The exit surface can be a toroidal lens, an optical plane, a corresponding ring-shaped Fresnel mirror or a full-phase optical component. (Sixth Direct Type Liquid Crystal Display Backlight Plate Implementation Type) The background optical assembly may also be a reflective conical surface, see Fig. 3d. The cone combined reflecting surface 247 converts the incident light into conical light, and the cone subsequent reflecting surface 245 reflects the reflected light to the same universal direction to form a corresponding tapered light. The second reflected light is then emitted through the annular exit surface 246. The diffused beam behind the background optical assembly is discontinuous in space, so for this purpose, an optical diffusing surface is added to form a uniform, bright continuous illumination. (Seventh direct type liquid crystal display backlight plate implementation type) The above-mentioned reflecting surface and subsequent combined reflecting surface, their reflecting surfaces may also have optical curved surfaces for optical focusing or diverging. The optical curved surface may be a reflective surface or a total reflection surface coated with a reflective film. Direct-type liquid crystal display backlight panel composed of a direct-type liquid crystal display backlight structure with multiple optical curved surfaces 9 M435621 For the implementation example, please refer to FIG. 4a, a direct-lit type liquid crystal display backlight structure with multiple optical curved surfaces, and an implementation example thereof. 4 b, a cross-section of a direct-type liquid crystal display backlight panel composed of a plurality of embedded background optical optical assemblies (400a, 400b.._40〇n). The LED beam is the incident light B0, and the incident light is decomposed into at least two reflected lights B11 by a conical reflecting curved surface (141 a, 141 d) composed of at least two reflecting surfaces of the spectroscope, and the subsequent reflecting curved surface (142a, 142d) is an optical curved surface having an optical concentrating or diverging effect for the reflecting surface. The optical curved surface may be a reflective surface or a totally reflective surface coated with a reflective film. The reflected light is reflected in the same direction by the above optical curved surface and the light beam is diffused to form a corresponding multi-beam diffusion secondary reflection pupil 33. The diffused beam is discontinuous in space, so for this purpose, an optical diffusing surface is added to form a uniform, bright continuous illumination. (Eighth direct type liquid crystal display backlight implementation type) Please refer to the splitter implementation case of the four reflecting surfaces of Fig. 4c. The spectroscope is a four-sided conical reflecting surface composed of four reflecting surfaces (丨43a..·1 43d), which splits the incident light into four beams, and the four-sided subsequent reflecting curved surfaces (144a...144d) are optical reflecting groups for the reflecting surface. Optical or divergent optical surface. The optical curved surface may be a reflective surface coated with a reflective film, a total reflective surface or an optical plane. The reflected light is reflected in the same direction by the optical curved surface and the light beam is diffused to form a corresponding multi-beam diffused secondary reflected light. After the diffusion of M435621, the beam is discontinuous at the workpiece, so the optical diffusing surface is added for this purpose - a uniform 'bright continuous illumination is formed. (The ninth direct-type liquid crystal display backlight panel implementation type) The spectroscopic backlight of the always-on liquid crystal display backlight panel can also be a reflective conical surface 145 kiss. See Figure 4 for the heart-reflecting conical surface to convert the incident light into a conical light. The reflective curved surface 46 reflects the reflected light in the same direction to form corresponding conical diffused light. The diffused beam is discontinuous between the turns, so for this purpose, an optical diffusing surface is added to form a uniform, bright continuous illumination. The above-mentioned illumination light source array can also be embedded in the backlight of the background optical assembly, and the direct-type liquid crystal display backlight structure composed of the backlight structure of the direct-lit liquid crystal display is referred to FIG. 5 or FIG. A plurality of backlights The optical assembly is provided with an embedded hole E丨 placed in the background optical assembly. • The light source array E can be embedded in the embedded hole E i . The above-mentioned beam splitter t-core may also have a central aperture Η丨〇 which allows part of the light to pass through to form another direct beam Βη. See Figure 7 for an implementation example. The central aperture 10 can also be a central optical surface that converges or diverges, allowing part of the light to pass through to form another concentrated or divergent beam. The central aperture 10 can also be a lens, a Fresnel mirror, a full phase optical component, and a curved lens. The direct-type liquid crystal display backlight structure arrangement is combined with different anti-M435621 'reflective' and total-cone matrices. We show different beamsplitters, beam diffusers, and optical diffusing surfaces that can produce illumination for the LCD screen, and combinations thereof. However, it is not possible to fully introduce all the modified cases that can be reached by those familiar with the technology. But all these changes do not exceed the scope of our patent claims.
