Or the distribution of transmittance, the white light refracted by the holographic dichroic mirror into red, green, and blue is divided into different angles of incidence, and are incident on the liquid crystal panel, so that all the light that would have been absorbed is released, so that The brightness of the light spot projected on the screen is increased several times. When the viewers watch the movie, they will not be affected by the external light, which is also the purpose of our invention. When different driving voltages are applied to the liquid crystal molecules, the liquid crystal molecules will change their alignment state, so that the light passing through the liquid crystal panel will change its polarization characteristics. Therefore, if the light emitted by the light source is first passed through a polarizing plate to make the light linearly polarized, and then different voltages are applied to the liquid crystal molecules, the polarization direction of the light changes with the voltage. When the polarization direction is different from that of the second linear polarizing plate, the light will be absorbed. If the polarization direction of the light is the same, the light can pass through the device without being absorbed. If the polarization direction is at an angle θ different from the polar direction of the second linear polarizer, the energy of the emitted light will be COS Θ times when it is not absorbed, so by changing the driving voltage, we can Get black and white images on the screen. On the other hand, if you want to obtain a color image, the spatial red, green, and blue color separation methods are generally used. That is, on the LCD panel, red and green are added to the arrangement such as M triangles or stripes. Or blue ochre mirrors. Each color filter only passes light of a certain wavelength band, so what you see on the screen will be three red, green, and M light spots staggered. Because the human eye has limited resolution, when you look at it from a distance, you will experience a mixture of red, green, and M points. Different proportions of three-color light will form different colors in the brain.

Description of the Invention (7) The working principle of the color LCD projection television When light passes through the first polarizing plate, more than half of the energy can be absorbed, and the aperture ratio of the liquid crystal is mostly between 30% and 40%. In addition, the extinguishing mirror allows only one of the three primary colors to pass through, and the rest Both colors will be absorbed, and only 1/3 of the light can pass through. The entire LCD module will absorb 0.5X0, 3 X 1/3 = 95% of the light, and only 5% of the light can pass through the device. , Causing the monolithic LCD projection TV to suffer from insufficient brightness. If you increase the bulb wattage, To increase the brightness, the energy absorbed by the polarizing plate and the liquid crystal panel will also increase relatively. After this energy is converted into thermal energy, it is easy to damage the liquid crystal and the polarizing plate, and the reliability is reduced. Therefore, frost requires other methods to solve this. In order to solve the above-mentioned problem of insufficient brightness, some inventions have adopted a method such as chirping or a quarter-wave retarder to change all the polarized light beams emitted by the lamp source to the same polarity. The energy absorbed by the panel can be effectively used, and the brightness can be more than doubled. However, the energy of the light absorbed by the liquid crystal panel will also be relatively increased, and the wattage that the M bulb can use must be limited. The operating temperature of the LCD Will become the final determinant of the brightness that this device can finally achieve; on the other hand, some inventions add a layer of microlens manufactured by the ion-exchange method to the liquid crystal panel, so that the original will be blocked by the pixel electrode The light can also pass through the liquid crystal panel smoothly, so that the brightness can be effectively improved. However, because the light collected by the microlenses is on the calender, it will make the filter The material tends to undergo chemical aging and gradually fade, which affects the quality of the picture. The main purpose of the present invention is to solve the above-mentioned shortcomings. We use the whole (please read the precautions on the back before filling this page).

As shown in Fig. 2, the holographic dichroic mirror 40 is a three-layer volume hologram (Volio fio 丨 ogran) or as shown in Fig. 3. Color dichroic mirror (dichroic mirror) and the three-layer volume holographic holographic dichroic mirror 40 is the first layer is a holographic film that only works on red light 401 ^ The second layer is only on blue light The holographic image 4 02, the third layer is a holographic film 40 3 that only acts on light recording; the second layer is a holographic dichroic mirror 40 2 that is a holographic image that acts only on red light. The hologram 404, the second layer is the hologram 405 and the dichroic filter 406 which only act on blue light, and the arrangement order of the hologram K of the above layers can be changed according to different needs, for example, the green light first, and then Effect on red light and so on; and the method and process for manufacturing the aforementioned volume hologram, as shown in the fifth figure A, the object light 7 1 and the reference light 7 2 are in a photosensitive material (recording medium Re medium) The interference fringe 7 3 is formed on 70. When the photosensitive material 7 is processed by development, fixing, bleaching and other procedures, the internal transmittance or phase of the photosensitive material, and the refractive index will change periodically with the interference fringe 73. For example, the fifth As shown in Figure B, when the reconstructed light 8 1 is irradiated on the taken hologram 8 0 (Hologram), the original object light 8 will be obtained in the direction that satisfies the Brig reflection condition 2d sin0 = ηλ. 2 the same real image. Because for a specific angle Θ and fringe spacing d, only part of the wavelength satisfies the Bragg cond i Uon, so the light except for a specific wavelength is reflected and deflected by a certain angle Outside. The rest of the light will pass through the hologram 8 0. Therefore, the appropriate arrangement of the values of the distance d and the angle Θ will allow the holograms of different layers 80 to deflect different colors of light-9 ^ This paper is suitable for the national standards of Sichuan and Ningguo ^ that) 6 4 specifications ( _2 丨 0/297 mm) The shoulder of the Central Standards Bureau of the Ministry of Economic Affairs f Cooperatives 46 ^ 7 7 8 A7 B7 V. Description of the invention (/ β) Toothed binary Fresnel miniature lens (such as seventh, Figure 8), but microlenses made in other ways can still be used in the present invention. In addition, there are many methods for manufacturing the above-mentioned Fichler micro-lens array. Common methods such as electron beam lithography or 1C etching are used to make the matrix, and then K-die casting or injection is used for mass production. And the light of different angles will be concentrated in different Pi xel through the action of the micro lens row, as shown in the ninth figure. Therefore, each micro lens corresponds to three pixels: red, green, and blue. Since there are many ways to arrange the pixels on the LCD panel, such as stripes, triangles, etc., the shape of the K micro lenses may be cylindrical, six Different shapes, such as angles, depend on different applications. In addition, the light emitted from different Pi xel passes through the function of Fresnel micro lens and projection gimmick, and can be printed on the screen to produce a color image. Compared with the previous technicians, the present invention obviously simplifies collimation (al Unment) problem: In the conventional technology, each dichroic mirror must be properly adjusted in angle, otherwise problems such as color mixing or light unable to pass through the device are easily generated. The present invention obviously eliminates the above difficulties; because The holographic dichroic mirror is adhered to the same glass plate, so the volume of the projection device is greatly reduced compared with ordinary ones, and it has the advantages of small size and light weight. Please refer to the tenth circle, which is a schematic diagram of an embodiment of the present invention. As shown in the figure: the light 1 0 a in the light bulb 1 Oa passes through the condenser mirror 30 a to become parallel light through the reflector 20 a, and enters the transmissive holographic dichroic mirror 40 a. The holographic dichroic mirror 40 a is divided into two calendars. The first layer deflects the red light and deflects the holographic dichroic mirror 4 1 a. The second layer deflects the blue light and deflects the holographic dichroic mirror 4 2 a. The green light is completely unchanged. Moving forward, the separation order on K can also be -11-This paper size is applicable to China National Standard (CNS) Λ4 size (210X29?

The description of the invention (//) has changed, such as deflection of the blue light first, and then deflection of the light recording, red light to maintain the original direction to pass. The recording, red, and blue parallel light that is deflected into three different angles is converged by the holographic microlens row 43a to the corresponding pixels, and then emitted from the device. Another way is to combine the dichroic mirror and the microlens array into one to form a penetrating dichroic microlens array. When shooting such a hologram, the object light is a point light source corresponding to the location of the liquid crystal daylight. The reference light is parallel light. When reconstructed with a reversed reference beam, the light will be deflected and focused toward the original liquid crystal location. When a three-dimensional transmissive volume full-photograph is used that meets different Brig conditions, the The white light is divided into red, recording, and blue light and directly focused to the corresponding liquid crystal pixel level, thus eliminating the need for the lens array. This structure is easier to arrange and the cost is lower. (As shown in Figures 14A and B, how to make and use it) Please refer to Figure 11, which is a schematic diagram of an embodiment of the present invention. As shown in Figure ：: The light 1 0 1 b emitted from the bulb 1 Ob is converted into parallel light by the reflector 20 b through the condenser 30 b, and then the person hits the two-color extinguishing mirror 40 b, and then enters the two-color 漶 mirror 5 0 b. The holographic microlens row 60b is shot onto the liquid crystal panel 70b. The holographic microlens row 60 b is used to increase the brightness by 0 謓 Refer to FIG. 12, which is a diagram showing a practical example of the present invention. As shown in the figure: the light 101C in the light bulb 10c is incident on the holographic dichroic mirror 40c through the condenser 30c through the reflecting mirror 20c. The holographic dichroic mirror 40c is composed of a undulating surface hologram This kind of undulating surface hologram can affect the phase of incident light. Enable 1 to focus on the first-order mirror light. Because different light paths have different optical paths, white light is incident in the first order. In the direction of the light emitted by Μ, different wavelengths of light will reach different angles -12-This paper is applicable in the national standard (CNS) Λ4 specification (210X29?

A volume hologram or a two-layer volume hologram and a dichroic mirror are used to form a general one. As for the use of a transmissive holographic dichroic mirror, as shown in FIG. 6B, the white light is incident at 8 1 a. At 80 a of the full-frame image, three red lights 82a, green 83a, and blue 84a are penetrated at different angles, and the three penetrated lights need to meet the Brig's reflection conditions for the wavelength of light. The basic structure and principle of the transmissive holographic dichroic mirror is similar to that of the reflective type, except that When shooting, the object light and the reference light are located on the same side of the recording material. As shown in Figure 6A, the object light 7 1 and reference light 7 2 are on the same photosensitive material (recording medium Re cording Medium) 7 0 On the side, there are many kinds of photosensitive materials used in recording materials, such as silver halide, photoresists, photopolymers, etc. Photopolymerization problems can use a large number of ultraviolet irradiation methods.
