Description

  The present invention relates to a technical field of a mounting case that houses an electro-optical panel such as a liquid crystal panel, and an electro-optical device module that includes the electro-optical panel and a mounting case that houses the mounting case.

  An electro-optical panel such as a liquid crystal panel is not mounted on a projection device such as a projector alone, but is mounted on the projection device as an electro-optical device module housed in a mounting case. For example, a light valve that modulates light It is used as a light modulation device. During operation of a projection device such as a projector, the electro-optical device module is irradiated with powerful light emitted from a light source, and thus the malfunction of the electro-optical panel is likely to occur as the temperature of the electro-optical panel increases. There is a point. In addition, there is a problem that the reliability of the electro-optical panel is lowered.

  In order to solve these problems, various techniques for reducing the temperature rise of the electro-optical panel have been disclosed (for example, see Patent Document 1).

JP 2004-45680 A

  However, according to the technique disclosed in Patent Document 1, it is difficult to reduce the light energy absorbed by the case, and thus it is difficult to solve the temperature increase of the electro-optical panel. In addition, it is necessary to provide an air blowing means such as a fan for blowing cooling air, and an apparatus not directly related to image display by the projector is required. Accordingly, there arises a problem with a design change for a projection apparatus such as a projector.

  Therefore, the present invention has been made in view of the above problems and the like, and for example, to provide a mounting case and an electro-optical device module capable of suppressing a temperature rise of a liquid crystal panel mounted on a projection device such as a projector. Let it be an issue.

  In order to solve the above problems, a mounting case according to the present invention is provided with a case main body portion that accommodates an electro-optical panel, and a window portion that is provided in the case main body portion and faces a pixel region of the accommodated electro-optical panel. And is provided on one surface of the case main body so as to surround the window portion, and is provided along the edge of the window portion with a light reflecting film having a higher light reflectance than the one surface. And an antireflection film provided on a wall surface defining the window portion by intersecting with the one surface.

  According to the mounting case according to the present invention, the case main body only needs to have a configuration capable of accommodating an electro-optical panel such as a liquid crystal panel, and may be configured by combining a plurality of members, for example. .

  The window is provided in the case main body, and the pixel region of the accommodated electro-optical panel faces. Here, the pixel region is a region corresponding to a display region in which the electro-optical panel displays an image. For example, in the case of a liquid crystal light valve, a region where light emitted from a light source can enter the electro-optical panel. It is. In the projector, the light incident on the pixel region is modulated by the electro-optical panel, and the modulated light is emitted from the display region of the electro-optical panel, so that an image can be displayed.

  The light reflecting film is provided on one surface of the case main body so as to surround the window portion, and has a light reflectance higher than that of the one surface. That is, the light reflecting film is, for example, a light source on the surface of the case main body that faces the pixel area from the window in a state where the electro-optical panel housed in the mounting case is disposed in a projection device such as a projector. Is provided on one surface of the case main body portion facing the side where the is disposed. Therefore, the light emitted from the light source does not reach one surface of the case body and is reflected by the light reflecting film. Here, since the light reflectance of the light reflecting film is larger than the light reflectance of one surface of the case body, the amount of light reflected by the light reflecting film is reflected by one surface of the case body. Larger than the amount of light. Therefore, by providing the light reflecting film, the energy of light absorbed by the case main body can be reduced, and the temperature rise of the mounting case can be suppressed. Such a light reflecting film can be composed of a metal film such as Ag or Al.

  Here, from the viewpoint of suppressing the temperature rise of the mounting case, it is also conceivable to provide a light reflecting film on the wall surface extending along the edge of the window portion and defining the window portion. However, when a light reflecting film is formed on such a wall surface, the light reflected by the light reflecting film is obliquely incident on the pixel region, and a striped display defect is displayed at the edge of the image displayed by the electro-optical panel. End up. In addition, even if the light reflecting film is not provided on the wall surface, the light is reflected by the wall surface to a greater or lesser extent.

  Therefore, in the mounting case according to the present invention, an antireflection film is provided on the wall surface that defines the window portion by extending along the edge of the window portion and intersecting the one surface. According to such a light reflection preventing film, light reflected from the wall surface among light incident on the window from the light source can be reduced, and light incident obliquely on the pixel region can be reduced. Accordingly, it is possible to reduce the display of striped display defects at the edge of the image displayed by the electro-optical panel.

  As described above, according to the mounting case of the present invention, the temperature increase of the electro-optical panel can be suppressed during the operation of the electro-optical panel, so that the display performance of the electro-optical panel can be prevented from being lowered. In addition, the display performance of the electro-optical panel can be improved by reducing striped display defects.

  In one aspect of the mounting case according to the present invention, the mounting case may include a protective film that is provided on the light reflecting film and protects the light reflecting film.

  According to this aspect, for example, even when the light reflecting film is formed of an easily oxidized metal film such as Ag or Al, the oxidation of the light reflecting film can be reduced. Therefore, it is possible to suppress a decrease in the light reflectance of the light reflecting film.

  In another aspect of the mounting case according to the present invention, the light reflection preventing film includes a first light reflection preventing film provided along the wall surface, and an oxidation formed by partially oxidizing the light reflection film. You may comprise from the 2nd light reflection film | membrane prevention film comprised from the film | membrane.

  According to this aspect, since the light reflection preventing film can be formed by oxidizing a part of the light reflection film, the light reflection preventing film can be formed by a simple manufacturing process.

  In order to solve the above problems, an electro-optical device module according to the present invention is provided with an electro-optical panel, (i) a case main body that houses the electro-optical panel, and (ii) the case main body. A window part facing the pixel region of the accommodated electro-optic panel; (iii) a light reflection provided on one surface of the case body so as to surround the window part and having a light reflectance higher than that of the one surface And (iv) a mounting case provided along an edge of the window portion and having a light reflection preventing film provided on a wall surface defining the window portion by intersecting the one surface. .

  According to the electro-optical device module according to the present invention, since the above-described mounting case is provided, the temperature increase of the electro-optical panel can be suppressed during the operation, and a high-quality image can be displayed over a long period of time. . In particular, in an electronic device such as a projector, since the intensity of light emitted from a light source is strong, a high-quality image can be displayed by taking advantage of the electro-optical device module according to the present invention.

  Such an operation and other advantages of the present invention will become apparent from the embodiments described below.

  Hereinafter, embodiments of a mounting case and an electro-optical device module according to the present invention will be described with reference to the drawings.

<1: Projector configuration>
First, a configuration of a projector using the electro-optical device module according to the present embodiment as a light valve will be described with reference to FIG. Here, the description will focus on the optical system incorporated in the optical unit. FIG. 1 is a schematic cross-sectional view of a projector. The projector according to the present embodiment is constructed as a multi-plate color projector in which three liquid crystal light valves are used as a set.

  In FIG. 1, a liquid crystal projector 1100, which is an example of a double-plate type color projector in the present embodiment, prepares three liquid crystal light valves including an electro-optical device in which a drive circuit is mounted on an element substrate. The projector is configured as a light valve 100R, 100G, and 100B. Each of the liquid crystal light valves 100R, 100G, and 100B is an example of the “electro-optical device module” in the present invention.

  In the liquid crystal projector 1100, when projection light is emitted from a lamp unit 1102 of a white light source such as a metal halide lamp, light components R, G, and R corresponding to the three primary colors of RGB are obtained by three mirrors 1106 and two dichroic mirrors 1108. The liquid crystal light valves 100R, 100G, and 100B corresponding to the respective colors are respectively guided to B. At this time, in particular, the B light is guided through a relay lens system 1121 including an incident lens 1122, a relay lens 1123, and an exit lens 1124 in order to prevent light loss due to a long optical path. Light components corresponding to the three primary colors modulated by the liquid crystal light valves 100R, 100G, and 100B are synthesized again by the dichroic prism 1112 and then projected as a color image on the screen via the projection lens 1114.

  The liquid crystal light valves 100R, 100G, and 100B include, for example, an active matrix drive type liquid crystal panel that uses TFTs as switching elements as described below.

  When the liquid crystal projector 1100 is driven, the temperature of the liquid crystal light valve 100 rises due to the projection light from the lamp unit 1102 that is a powerful light source. At this time, if the temperature rises excessively, the liquid crystal in the liquid crystal light valve 100 deteriorates, or the transmittance is uneven due to the appearance of hot spots due to partial heating of the liquid crystal panel due to unevenness of the light source light.

  Therefore, in the present embodiment, in particular, the liquid crystal light valve 100 is configured as follows to efficiently suppress the temperature rise. Note that the liquid crystal light valves 100R, 100G, and 100B differ from each other only in the function of modulating red light, green light, and blue light, and have the same basic configuration. Therefore, hereinafter, the configuration of the liquid crystal light valve 100 will be described.

Is provided. The sampling circuit 7 is provided so as to be covered with the frame light shielding film 53 on the inner side of the seal region along the one side. The scanning line driving circuit 104 is provided along two sides adjacent to the one side so as to be covered with the frame light shielding film 53.

  On the element substrate 10, vertical conduction terminals 106 for connecting the two substrates with the vertical conduction material 107 are disposed in regions facing the four corner portions of the counter substrate 20. Thus, electrical conduction can be established between the element substrate 10 and the counter substrate 20.

  On the element substrate 10, lead wirings 90 are formed for electrically connecting the external circuit connection terminals 102 to the data line driving circuit 101, the scanning line driving circuit 104, the vertical conduction terminal 106, and the like.

Further, the liquid crystal layer 50 is made of, for example, a liquid crystal in which one or several types of nematic liquid crystals are mixed, and takes a predetermined alignment state between the pair of alignment films.

  2 and 3, on the element substrate 10, in addition to the data line driving circuit 101, the scanning line driving circuit 104, etc., a precharge signal having a predetermined voltage level is applied to a plurality of data lines as an image signal. In addition, a precharge circuit to be supplied in advance of each other, an inspection circuit for inspecting the quality, defects, etc. of the electro-optical device during manufacture or at the time of shipment may be formed.

FIG. 4 is an equivalent circuit diagram of various elements, wirings, and the like in a plurality of pixels formed in a matrix that forms the image display region 10a of the liquid crystal panel 500.

  In FIG. 4, each of a plurality of pixels formed in a matrix forming the image display region 10 a of the liquid crystal panel 500 includes a pixel electrode 9 a and a TFT 30 for switching control of a voltage applied to the pixel electrode 9 a. The data line 6 a formed and supplied with an image signal is electrically connected to the source of the TFT 30.

(Configuration of electro-optical device module)
Next, a specific configuration of the liquid crystal light valve 100 in which the liquid crystal panel 500 is housed in the mounting case 601 will be described with reference to FIGS.

  FIG. 5 is an exploded perspective view showing the mounting case 601 included in the liquid crystal light valve 100 together with the liquid crystal panel 500. FIG. 6 is a plan view of the liquid crystal light valve 100. 7 is a cross-sectional view taken along the line VII-VII ′ of FIG. In FIG. 7, the liquid crystal layer 50 is not shown.

  In FIG. 5, an external circuit connection terminal 102 (see FIG. 1) included in the liquid crystal panel 500 is electrically connected to a flexible printed wiring board (hereinafter abbreviated as FPC) 501. A dustproof substrate 400 is provided on each of the element substrate 10 and the counter substrate 20 on the surface opposite to the surface facing each other with the liquid crystal layer 50 interposed therebetween. The polarizing plate, the retardation plate, and the like may be attached to the outer surface of the liquid crystal panel 500 or may be provided as part of the optical system of the liquid crystal projector 1100.

  As shown in FIG. 5, a mounting case 601 that is an example of the “mounting case” of the present invention includes a frame 610 (that is, a first holding member) that houses the liquid crystal panel 500, and a cover member 620 that covers the frame 610 ( That is, the second holding member is provided. The frame 610 and the cover member 620 constitute an example of the “case body” of the present invention. The cover member 620 is combined with the frame 610 by hooking hooks 627 on both side edges to the claw portions 637 formed on the side surfaces of the frame 610.

  The liquid crystal panel 500 is accommodated in a direction in which the counter substrate 20 side faces the frame 610, and the outer surface on the element substrate 10 side is covered with a cover member 620. That is, in the liquid crystal light valve 100, light is incident from a window portion 616, which is an example of the “window portion” of the present invention, provided in the frame 610 in a state where the liquid crystal light valve 100 is disposed on the projector 1100. It is assumed that modulated light is transmitted from the cover member 620 through the liquid crystal panel 500 from the light transmission region 400a facing the portion 616 (in FIG. 1, the dichroic prism 1112 has not the frame 610 but the cover member 620). Are facing each other). The liquid crystal panel 500 is housed in the frame 610 by being fixed to the frame 610 by an adhesive while being surrounded by the frame 610 from the peripheral side. Therefore, the liquid crystal panel 500 is surrounded by the frame 610 from the peripheral side. Note that the peripheral area located around the light transmission area 400 a corresponding to the image display area 10 a in the liquid crystal panel 500 in the state of being accommodated in the mounting case 601 is covered with the frame 610. A protective film 611 is provided on the frame 610. A light reflection preventing film 617 is provided on a wall surface extending along the edge of the window portion 616 and defining the window portion 616.

  The cover member 620 includes a frame-shaped main body provided with a window portion 625, and hooks 627 on both sides of the main body. The window 625 is opened so that the image display area 10a faces in order to extract light emitted from the image display area 10a (see FIG. 2) of the liquid crystal panel 500.

  As shown in FIG. 6, the frame 610 includes a main body portion 613, a mounting portion 614, a claw portion 637, an intake port 710, a protective film 611, a light reflection film 618, and a light reflection prevention film 617.

  In FIG. 6, the main body portion 613 includes a window portion 616 that is shaped to match the shape of the liquid crystal panel 500, so that the inside is cut out. The window 616 is opened to face the image display area 10a in order to transmit light to the image display area 10a (see FIG. 2) of the accommodated liquid crystal panel 500. Therefore, the light emitted from the lamp unit 1102 in the liquid crystal projector 1100 shown in FIG. 1 can enter the light transmission region 400 a of the liquid crystal panel 500 through the window 616.

  In FIG. 6, mounting portions 614 are provided at the four corners of the frame 610, and mounting holes 615 are provided in each of the mounting portions 614. The mounting holes 615 are used when the liquid crystal light valve 100 is mounted in the liquid crystal projector 1100 as shown in FIG. That is, the liquid crystal light valve 100 is mounted in the liquid crystal projector 1100 by screwing the liquid crystal light valve 100 to the liquid crystal projector 1100 using a screw that passes through the mounting hole 615. Therefore, the liquid crystal panel 500 can be stably mounted in the liquid crystal projector 1100. Therefore, for example, it is possible to prevent the image display area 10a from being displaced with respect to the attachment position that is an optical reference position.

  Furthermore, as shown in FIG. 6, in this embodiment, the mounting case 601 is fixed at four points by providing the attachment holes 615 at the four corners of the frame 610. In order to fix the liquid crystal light valve 100 in the liquid crystal projector 1100, it is preferable that at least three mounting holes are provided.

  The frame 610 includes an intake port 710 that opens on the side surface of the frame 610. According to the intake port 710, it is possible to supply a cooling fluid to the liquid crystal panel 500 housed in the mounting case 601 formed by assembling the frame 610 and the cover member 620, thereby suppressing the temperature rise of the liquid crystal panel 500. .

  6 and 7, the light reflecting film 618 extends to the surface of the frame 610 so as to surround the window 616, and has a light reflectance higher than that of the surface. That is, the light reflecting film 618 is a surface facing the light incident side that is the side where the light transmission region 400a faces from the window 616 in a state where the liquid crystal panel 500 accommodated in the mounting case 610 is disposed in the projector 1100. Is provided. Therefore, the light irradiated to the liquid crystal light valve 100 does not reach the surface of the mounting case 601 but is reflected by the light reflecting film 618. Here, since the light reflectance of the light reflecting film 618 is larger than the light reflectance of the surface of the main body 613, the amount of light reflected by the light reflecting film 618 is the amount of light reflected by the surface of the main body 613. Larger than the amount of light. Therefore, by providing the light reflecting film 618, the energy of light absorbed by the mounting case 601 can be reduced, and the temperature rise of the mounting case 601 can be suppressed. Note that such a light reflecting film 618 can be composed of a metal film such as Ag or Al.

  Here, from the viewpoint of suppressing the temperature rise of the mounting case 601, it is conceivable to provide a light reflecting film on the wall surface 619 extending along the edge of the window portion 616 and defining the window portion. However, when a light reflection film is formed on such a wall surface 619, the light reflected by the light reflection film is obliquely incident on the light transmission region 400a, and a striped display defect is formed at the edge of the image displayed by the liquid crystal panel 500. Will occur. In addition, even when the light reflecting film is not provided on the wall surface 619, the light is reflected by the wall surface 619 to a greater or lesser extent.

  Therefore, in the mounting case 601, the light reflection preventing film 617 is provided on the wall surface 619 that defines the window 616. According to such a light reflection preventing film 617, light reflected by the wall surface 619 among light incident on the window portion 616 can be reduced, and light incident obliquely on the light transmission region 400a can be reduced. Therefore, it is possible to reduce the occurrence of striped display defects at the edge of the image displayed by the liquid crystal panel 500.

  The protective film 611 is provided on the light reflecting film 618 and protects the light reflecting film 618. More specifically, for example, when the light reflecting film 618 is made of an easily oxidized metal film such as Ag or Al, the protective film 611 serves as an antioxidant film that prevents the light reflecting film 618 from being oxidized. It is formed. According to the protective film 611, it is possible to reduce the oxidation of the light reflection film 618, and it is possible to suppress a decrease in light reflectance.

  As described above, according to the mounting case 601 according to the present embodiment and the liquid crystal light valve 100 in which the liquid crystal panel 500 is accommodated in the mounting case 601, the temperature of the liquid crystal panel 500 increases during the operation of the liquid crystal panel 500. Therefore, it can suppress that the display performance of the liquid crystal panel 500 falls. In addition, the display performance of the liquid crystal light valve 100 can be improved by reducing the striped display defects.

In the following description, portions common to the mounting case 601 and the liquid crystal light valve 100 described above are denoted by common reference numerals, and detailed description thereof is omitted.

  In FIG. 8A, in the mounting case 601a according to the present example, the light reflection preventing film 617a partially oxidizes the light reflection film 618a and the first light reflection preventing film 617a1 extending along the wall surface 619a. The second light reflection film preventing film 617a2 is formed of the formed oxide film.

  According to such an antireflection film 617a, since the antireflection film 617a can be formed by oxidizing a part of the antireflection film 618a, the antireflection film 617a can be formed by a simple manufacturing process.

  In FIG. 8B, in the mounting case 601b according to this example, the light reflection preventing film 617b is formed on the wall surface 619b so as not to overlap the light reflecting film 618. According to such an antireflection film 617b, the light incident obliquely on the light transmission region 400a can be reduced similarly to the above-described antireflection film, so that the display performance of the liquid crystal light valve 100b can be improved. is there.
