In such an assumed structure, it is possible to prevent the leaked adhesive material from adhering to the drive circuit or the backlight and causing an abnormal operation by suppressing leakage of the optical adhesive material before curing to the side space of the display unit. Becomes

  However, in recent years, use of a curved outer panel having a display front surface curved in a convex shape toward the front of the display and a display back surface curved in a concave shape toward the front of the display has been demanded. Is coming. Therefore, when such a curved outer panel is applied to the disclosed unit of Patent Document 1, a gap is likely to be formed between the concave display back surface and the resin member, and therefore the optical adhesive before curing is displayed through the gap. Leakage into the side space of the panel may lead to malfunction. In addition, in order to prevent the resin member from protruding from the outer portion of the display region, which is desirably secured large on the display screen of the display panel, and the visibility of the displayed light image is reduced, the resin member is formed to be narrow.

Good. Alternatively, the display unit 1 may be applied to an acoustic panel that displays acoustic information such as the volume inside the vehicle and acoustic operation buttons as the display optical image 2, and receives a touch operation related to the acoustic information from the user. Alternatively, the display unit 1 may of course be applied to various in-vehicle electrical components other than those panels.

  As shown in FIG. 1, the display unit 1 includes a housing 10, a display panel 20, a drive circuit 30, a backlight 40, a curved outer panel 50, a protector 60, and an optical adhesive 70.

  The housing 10 is formed of, for example, an opaque resin or metal into a rectangular cup shape, and is provided with a light shielding property. The opening 100 of the housing 10 is directed toward the display front Df on the seat side where the user sits in the vehicle.

  The display panel 20 is formed in a rectangular flat plate shape as a whole. The display panel 20 is arranged in the housing 10 in the vicinity of the opening 100. As shown in FIGS. 1 to 3, lateral spaces Ss for arranging the drive circuit 30 are secured at the left and right and upper and lower lateral positions of the display panel 20. A rear space Sb for arranging the backlight 40 is secured behind the display panel 20. The display panel 20 forms a flat display screen 200 facing the display front Df as shown in FIGS. The display panel 20 has a flexible FPC board 21 protruding from the inside of the housing 10 to the outside as shown in FIGS. 1 and 3 in order to connect to a vehicle-mounted ECU such as a display ECU.

  As shown in FIG. 1, the display panel 20 of this embodiment is a color TFT liquid crystal panel configured by laminating a filter substrate 24 and a TFT substrate 25 between a pair of polarizing plates 22 and 23. The TFT substrate 25 is connected to the drive circuit 30 via the FPC substrate 21. The TFT substrate 25 has a plurality of pixels that form the display light image 2 (see FIG. 2). Each pixel of the TFT substrate 25 is driven by the drive circuit 30 in accordance with a control command received from the vehicle-mounted ECU, and forms the display light image 2 in cooperation with each other. The filter substrate 24 has a plurality of color filters for transmitting any one of RGB in correspondence with the display front Df of each pixel of the TFT substrate 25. The display light image 2 formed by driving each pixel of the TFT substrate 25 is color-displayed by passing through the color filter of the filter substrate 24.

  As shown in FIGS. 1 and 2, on the outer peripheral portion of the filter substrate 24, a light blocking portion 240 that blocks the transmission of light is provided instead of providing the color filter. As a result, a rectangular display area Ad that is surrounded by the light-shielding portion 240 having a rectangular frame shape and forms the display light image 2 for color display is set on the display screen 200 of the display panel 20. At the same time, on the display screen 200, a non-display area An in which the display light image 2 is not displayed by the light shielding portion 240 is set in a rectangular frame shape.

  The drive circuit 30 has a plurality of circuit components 31 for driving each pixel of the TFT substrate 25 of the display panel 20 to form the display light image 2. The circuit component 31 is, for example, a gate driver IC 310, a source driver IC 311, a resistance element 312, a capacitor 313, or the like. Here, the gate driver IC 310 and the source driver IC 311 are mounted on the extension part 250 formed by extending the TFT substrate 25 to the right side and the lower side part toward the display panel of the housing 10. It is arranged so as to be exposed in the lateral space Ss of 20. On the other hand, the resistance element 312 and the capacitor 313 are mounted on the FPC board 21 extending from the connection position with the TFT substrate 25 to the lower side position, so that the display panel 20 in the housing 10 is provided. It is arranged so as to be exposed in the lateral space Ss.

  As shown in FIG. 1, the backlight 40 is formed in a rectangular flat plate shape as a whole. The backlight 40 is arranged in the space Sb behind the display panel 20 in the housing 10. The backlight 40 has a light case 41, a light source 42, a light guide plate 43, and an optical film 44.

  The light case 41 is formed of, for example, an opaque resin or metal in a rectangular cup shape, and is provided with a light shielding property. The opening 410 of the light case 41 is directed toward the display front Df on the display panel 20 side. The interior of the light case 41 is exposed to the rear space Sb of the display panel 20 through the opening 410. Inside the light case 41, other constituent elements 41, 42, 43, 44 of the backlight 40 are arranged.

  The plurality of light sources 42 are composed of, for example, LED chips that emit white light. The light sources 42 are arranged along the side wall portion 411 of the light case 41 with a space therebetween. Each light source 42 is connected to the drive circuit 30 via a dedicated wiring and the FPC board 21. As a result, each light source 42 emits light by being energized by the drive circuit 30 in accordance with a control command received from the vehicle-mounted ECU.

  The light guide plate 43 is formed of, for example, a transparent resin in the shape of a rectangular flat plate, and is provided with translucency. The light guide plate 43 is arranged with its side surface 430 facing the respective light sources 42. The plurality of optical films 44 are formed into a rectangular sheet shape by using, for example, a transparent resin in which a diffusing agent is dispersed, and are given a light diffusing property. The optical films 44 are arranged side by side in order toward the display front Df of the light guide plate 43.

  With the configuration of the backlight 40 as described above, the light emitted from each light source 42 is sequentially diffused by being guided to each optical film 44 through the light guide plate 43. The light thus diffused is radiated toward the front Df of the display to illuminate the display panel 20 from behind. As a result, the display light image 2 formed by the display panel 20 is luminescently displayed in color.

  As shown in FIGS. 1 and 3, the curved outer panel 50 is made of, for example, transparent glass or the like in a curved plate shape so as to be translucent. The curved outer panel 50 is fixed to the housing 10 in a state of covering the opening 100 from the outside. The curved outer panel 50 has a display front surface 500 and a display rear surface 501 in the display front Df of the display panel 20. The display front surface 500 has a convex shape protruding toward the display front Df by being curved with a predetermined curvature up and down behind the display front surface 500. The display back surface 501 is curved with a predetermined curvature up and down, and thus has a concave shape that is recessed toward the display front Df.

  However, since the display front surface 500 and the display rear surface 501 of the present embodiment are formed in substantially the same partial cylindrical surface shape that is straight on the left and right, a substantially uniform thickness over the entire area of the curved outer panel 50. Is set. Further, in the display front surface 500 of the present embodiment shown in FIG. 1, a portion that covers the non-display area An and the side space Ss of the display panel 20 from the display front Df is curved by stacking a light-shielding print layer. It is formed as a decorative surface portion 502 that decorates the mold outer panel 50.

  As shown in FIGS. 1 and 3, the protective body 60 is formed in a rectangular sheet shape as a whole. The protective body 60 is provided with rigidity equal to or higher than that of a PET film having a thickness of, for example, about 0.1 mm. The protective body 60 is provided with translucency, for example, by including a transparent electrode in a transparent resin base material or laminating it. The protective body 60 is provided between the entire space of the display screen 200 including the display area Ad of the display panel 20 and the display rear surface 501 of the curved outer panel 50, and the side space Ss of the display panel 20 and the rear surface 501. It is located across the space. As a result, the protector 60 can protect the inside of the drive circuit 30 and the backlight 40 from the optical adhesive 70.

  In the protective body 60 shown in FIG. 1, the transparent electrode functions as a touch sensor by being connected to the drive circuit 30 via the dedicated wiring and the FPC board 21. Specifically, the transparent electrode senses a capacitance generated between the curved outer shell panel 50 in front of the display Df and the user's finger touching the display front surface 500 as a touch operation on the display front surface 500 by the user. .. The transparent electrode outputs the capacitance thus sensed to the vehicle-mounted ECU via the FPC board 21. As a result, the vehicle-mounted ECU outputs a control command given to the drive circuit 30 so as to switch the display form of the display light image 2 in response to the touch operation by the user.

  In the protective body 60 shown in FIGS. 1 and 3, the protective rear surface 600 on the display panel 20 side has a contact surface portion 601 that is in surface contact with the entire area of the display screen 200 and an exposed surface portion 602 that is exposed in the lateral space Ss. There is. In particular, the contact surface portion 601 of the present embodiment is such that the portion located in the display front Df of the light shielding portion 240 as shown in FIG. 1 is fixed to the non-display area An of the display screen 200 in the surface contact state in the entire circumferential direction. The surface portion 601a is secured in a rectangular frame shape surrounding the display area Ad. Here, the fixing surface portion 601a is fixed to the non-display area An of the display screen 200 by, for example, a double-sided tape or the like.

  The optical adhesive 70 is provided with translucency by UV-curing, two-component curing, or heat curing of an optical elastic resin such as a silicon-based or acrylic-based resin known as OCR. The optical adhesive 70 is cured in a sealed state between the protective front surface 603 of the protective body 60 facing the display front Df and the display rear surface 501 of the curved outer panel 50. As a result, the protective front surface 603 sandwiches the optical adhesive 70 with the display rear surface 501 in a rectangular range extending from the display front Df of the entire display screen 200 including the display area Ad to the display front Df of the lateral space Ss. The optical surface portion 604 is formed. At the same time, the protective front surface 603 has a rectangular frame shape with an outer peripheral portion contacting the display rear surface 501 in the entire circumferential direction in the display front Df of the lateral space Ss as a contact surface portion 605 adjacent to the outside of the optical surface portion 604. Is formed. Here, in particular, the contact surface portion 605 of the present embodiment is curved along the display rear surface 501 together with the rear exposed surface portion 602, so that the contact surface portion 605 is in surface contact with the display rear surface 501.

  The display unit 1 having the configuration described so far is manufactured by, for example, the following method. Specifically, first, as shown in FIG. 4, a rectangular area Al (a diagonally right upward hatching portion in FIG. 4) facing the optical surface portion 604 of the protective body 60 in a later step in the display back surface 501 of the curved outer panel 50. ), a liquid optical adhesive material 70 which is not yet cured is applied.

  Next, as shown in FIG. 5, the protective front surface 603 of the protective body 60 fixed by the fixing surface portion 601a to the display screen 200 of the display panel 20 in which the backlight 40 and the drive circuit 30 (not shown) are assembled. Then, the optical adhesive 70 on the curved outer panel 50 and the display back surface 501 of the panel 50 are simultaneously pressed, and then the optical adhesive 70 is cured. At this time, the optical adhesive 70 may be exuded to the contact interface of the protective front surface 603 as long as it does not leak from the contact interface between the contact surface portion 605 and the display rear surface 501. Further, at this time, it is desirable to suppress the bending in the portion of the protective body 60 where the exposed surface portion 602 is not held on the display screen 200. Therefore, it is possible to suppress the bending by pressing the protective front surface 603 of the protective body 60 against the optical adhesive 70 and the display rear surface 501 while adsorbing a predetermined portion of the exposed surface portion 602 with a suction jig.

  When the optical surface portion 604 of the protective front surface 603 is optically bonded to the display rear surface 501 by the thus cured optical adhesive material 70, the display panel 20, the backlight 40, and the drive circuit 30 are integrated into a housing as shown in FIG. It is housed in 10. Further, the display unit 1 is completed by fixing the curved outer panel 50 to the housing 10 by, for example, screwing.

(Effect)
The operation and effect of the display unit 1 described above will be described below.

  According to the display unit 1, the display panel 20 side is located between the entire area of the flat display screen 200 including the display area Ad in the display panel 20 and the display rear surface 501 curved in a concave shape in the curved outer panel 50. The protective body 60 is arranged so as to straddle the space Ss and the display rear surface 501. According to this, since the optical adhesive 70 is sealed between the protective body 60 and the display back surface 501, which will cover the entire display screen 200 and the lateral space Ss, the optical adhesive before curing is formed. It becomes difficult for 70 to leak into the lateral space Ss.

  Therefore, the drive circuit 30 exposed in the lateral space Ss can be protected from the adhesion of the optical adhesive 70. At the same time, it is possible to protect the backlight 40, which is exposed in the rear space Sb of the display panel 20 communicating with the lateral space Ss, from the adhesion of the optical adhesive 70. Moreover, the display light image 2 formed in the display area Ad of the display screen 200 is from the translucent protective body 60 covering the entire display screen 200 and the lateral space Ss to the space between the protective body 60 and the display rear surface 501. Permeability through the translucent optical adhesive 70 makes it difficult to impair visibility.

  From the above, in the display unit 1, it becomes possible to avoid the abnormal operation due to the adhesion of the optical adhesive 70 to the drive circuit 30 and the backlight 40, while ensuring the visibility of the display light image 2.

Then, it can be suppressed that it goes around to the lateral space Ss. According to this, it becomes possible to make sure the visibility of the display light image 2 at the same time and reliably avoid the operation abnormality.

  Further, according to the display unit 1, the optical adhesive 70 is displayed as the optical surface portion 604 of the protective body 60 in the range extending from the display front Df of the entire display screen 200 including the display area Ad to the display front Df of the lateral space Ss. It is sandwiched between the back surface 501. Thereby, the incident of the display light image 2 formed in the display area Ad can be restricted at the contact interface between the contact surface portion 605 adjacent to the outside of the optical surface portion 604 of the protective body 60 and the display back surface 501. It is possible to prevent the visibility of the displayed light image 2 from being reduced by the air layer at the contact interface. In addition, the optical adhesive 70 is sure to wrap around to the lateral space Ss due to leakage through the contact interface between the optical surface 604 and the display rear surface 501, which are inside the contact interface between the contact surface portion 605 and the display rear surface 501. Can be suppressed to. According to these, it is possible to surely ensure both the visibility of the display light image 2 and the avoidance of the operation abnormality.

  Further, according to the display unit 1, the protective body 60 having a touch sensor function of sensing a touch operation on the display front surface 500 also has a function of protecting the drive circuit 30 and the backlight 40 from the adhesion of the optical adhesive 70. Become. According to this, the two functions can be integrated in the protective body 60 to simplify the structure.
