CC sectional drawing of FIG.

(First Embodiment) A case where the display device of the present invention is applied to a vehicle instrument mounted on a vehicle will be described below with reference to FIGS.

  1 to 3, a vehicle instrument D as a display device according to the present embodiment includes a display means 10 as an instrument display capable of displaying various vehicle information, and a front side (viewer side) of the display means 10. A translucent member 20 disposed on the front side, a turn-back member 30 serving as a front-side housing disposed on the front side (viewer side) of the translucent member 20 (display means 10), and the side opposite to the viewer side The circuit board 40 disposed behind the display means 10 and a resin housing 50 that accommodates the circuit board 40 are mainly configured.

  The display means 10 is composed of, for example, a dot matrix type rectangular TFT liquid crystal display panel. In this case, a predetermined display area 11 is formed by a plurality of display pixels 60 as shown in FIG. In this display area 11, various vehicle information such as vehicle speed is displayed based on detection signals from various sensors mounted on the vehicle.

  In the case of this example, one display pixel 60 is constituted by three sub-pixels of the R pixel 61, the G pixel 62, and the B pixel 63, and there are a large number (a plurality) of the display pixels 60. Are provided in a matrix.

  The translucent member 20 is formed in a substantially flat plate shape with a translucent synthetic resin material, and is disposed between the display means 10 and the facing member 30. Further, in this case, the translucent member 20 is configured to cover only 11 portions of the display area provided corresponding to the display pixel 60 in the display unit 10 as shown in FIGS. 1 and 4. The other pixels 70 of the display means 10 at positions different from 60 are not covered.

  That is, the translucent member 20 here is not rectangular like the display unit 10 in its outer shape, and the portions corresponding to the other pixels 70 (that is, the upper left portion and the upper right portion in FIG. 4) are slanted. It has an irregular shape that is cut (that is, chamfered).

  The translucent member 20 is bonded (bonded) to the display means 10 (display area 11) with a translucent adhesive 21. As the translucent adhesive 21, for example, an ultraviolet curable optical adhesive (transparent resin) can be applied. And the viewer who visually recognizes the vehicle meter D can see through (view) various vehicle information displayed in the display area 11 through the translucent member 20 and the translucent adhesive 21.

  The facing member 30 is formed of, for example, a black synthetic resin material, and is configured as a covering member (visor) that covers the display unit 10 so as to define the visible region of the display unit 10 (that is, the display region 11). It has a housing body 32 having a circular opening 31 for exposing the 20 light-transmitting members corresponding to the region 11. In this case, it is assumed that the housing body 32 constitutes a main part of the turning member 30.

  And the housing | casing main-body part 32 is the horizontal wall part 33 mainly provided in the lower side of the vehicle instrument D, when the vehicle instrument D is divided into 2 parts up and down in FIG. 1, and the vehicle instrument in FIG. An inclined wall portion 34 provided mainly on the upper side of the vehicle instrument D when D is divided into approximately two equal parts vertically, and a peripheral wall portion 35 positioned on the upper end side and the lower end side of the vehicle instrument D in FIG. Further, the peripheral wall portion 35 includes a first standing wall portion 36 provided to be connected to the horizontal wall portion 33 on the lower end side of the vehicle meter D in FIG. On the upper end side of the measuring instrument D, a second standing wall portion 37 provided so as to be connected to the inclined wall portion 34 is provided.

  Further, as shown in FIG. 3, a pair for reflecting the colored light L emitted from the other pixels 70 of the display means 10 on the inclined wall portion 34 in the housing main body portion 32 at a position different from the display pixel 60. (Two) reflecting portions 38 are provided, and a pair of facing regions 39 that face (face to) each reflecting portion 38 through a predetermined gap portion S on the second standing wall portion 37 in the housing body portion 32. Is provided.

  Note that the facing region 39 is configured as a light emitting design region, which will be described later, capable of receiving colored light L, and the inclination angle thereof is steeper (becomes larger) than the inclination angle of the inclined wall portion 34. ) Is set as follows.

  Here, as in the case of the display pixel 60, one other pixel 70 is configured by three subpixels of the R pixel 71, the G pixel 72, and the B pixel 73 (see FIG. 4). The other pixels 70 not covered with 20 are locally provided in the upper left part and the upper right part of the vehicle meter D in FIG. 1 and are concealed by the inclined wall part 34. In other words, the other pixels 70 are not visible directly from the viewer side due to the presence of the inclined wall portion 34.

  In addition, for example, a white reflection layer having a high light reflectivity provided at the back surface portion of the inclined wall portion 34 corresponding to directly above the other pixel 70 can be applied to the reflection portion 38, and is controlled by a control portion described later. Therefore, it functions as a light reflecting surface that reflects colored light L (here, green light) emitted from other pixels 70.

  Here, the G pixel 72 among the R pixel 71, the G pixel 72, and the B pixel 73 constituting the plurality of other pixels 70 emits light, and the green colored light L is obtained. In order to obtain the blue colored light L, the B pixel 73 among the R pixel 71, the G pixel 72, and the B pixel 73 described above may be caused to emit light, and in order to obtain the red colored light L, the R pixel described above. The R pixel 71 of the 71, G pixel 72, and B pixel 73 may be caused to emit light, and in order to obtain white colored light L, all of the R pixel 71, G pixel 72, and B pixel 73 described above may be caused to emit light. Good.

  Further, the reflecting portion 38 is not limited to the white reflecting layer, and may be a reflecting surface in a mirror surface state having a high light reflectance, or may be a rough surface such as embossing that diffusely reflects the colored light L.

  Then, the colored light L reflected by the reflecting portion 38 is guided to the facing region 39 of the second standing wall portion 37 through the gap portion S. In other words, the colored light L emitted from the other pixels 70 is bent at a substantially right angle by the reflecting portion 38 so that the light path of the colored light L faces the reflecting portion 38 (facing the second standing wall portion). 37 is led (reflected) to the opposing region 39 of 37.

  Further, when the colored light L reflected to the facing area 39 hits the facing area 39, it is bent at a substantially right angle so that the optical path of the light is directed toward the viewer. At this time, the colored light L bent at a substantially right angle in the facing region 39 is an opening hole locally formed between the inclined wall portion 34 and the second standing wall portion 37 so as to be continuous with the gap portion S ( It passes through each of the openings (H).

  Thus, a viewer who visually recognizes the vehicle instrument D visually recognizes a pair (two) of light emitting design regions 80 (see FIG. 1) provided locally in the upper left part and the upper right part of the vehicle instrument D as visual information. can do. The light emitting design area 80 is displayed in green when the colored light L is applied to the facing area 39. For example, the light emitting design area 80 is used as an ambient display unit that displays whether or not the vehicle is eco-operated by light emission. Can do. For example, when the fuel consumption state of the vehicle is good (that is, the eco state), the viewer (driver) who visually recognizes the vehicle instrument D is illuminated by lighting the light emitting design region 80 in green. It can be easily recognized that the driving state is the eco driving state.

  The circuit board 40 is made of, for example, a hard wiring board provided with a wiring pattern, and a control unit 41 including a microcomputer for causing the display unit 10 to perform display operation, and various electronic components such as resistors and capacitors are connected to the wiring pattern. It is connected. The circuit board 40 is electrically connected to the display means 10 using a connection member (not shown) such as a flexible wiring board.

  The housing 50 is formed of, for example, a synthetic resin material, and accommodates the circuit board 40 and the like provided with the control unit 41 and the like for operating the display unit 10. 30 and fixed.

  As described above, in the present embodiment, the facing member 30 includes the housing main body 32 having the opening 31 for exposing the 20 light-transmissive members corresponding to the display area 11. Is different from the display pixel 60 and has a predetermined gap from the reflecting portion 38 for reflecting the colored light L emitted from the other pixels 70 of the display means 10 that are not covered by the light transmissive member 20. An opposing region 39 that faces the reflecting portion 38 via the portion S is provided, and the colored light L reflected by the reflecting portion 38 is guided to the opposing region 39 through the gap portion S.

  Accordingly, when the colored light L bent at a substantially right angle in the facing area 39 passes through the opening hole H, the viewer visually recognizes the light emitting design area 80 that is lit and displayed when the colored light L strikes the facing area 39. The appearance of the vehicle instrument D becomes interesting and novel, and the existing look-back member 30 is used (that is, the shape of the look-back member 30 is devised) to produce a novel look. It is possible to provide a display device that can be used.

  In the present embodiment, the display pixels 60 of the display unit 10 are covered with the translucent member 20, and other pixels 70 of the display unit 10 excluding the display pixels 60 are formed of the translucent member 20. Although the example which is not covered was demonstrated, both the display pixel 60 and the other pixel 70 seem to be covered with the translucent member 20 as shown in FIG. 5 as a 1st modification of this embodiment, for example. It is good also as a simple structure. In other words, in this case, the display unit 10 and the translucent member 20 are completely overlapped, and the translucent member 20 is bonded to the display unit 10 by the translucent adhesive 21.

  Even in such a configuration, the colored light L emitted from the other pixels 70 passes through the translucent adhesive 21 and the translucent member 20 and proceeds to the reflection unit 38, and then the reflection unit. The colored light L reflected at 38 sequentially reaches the gap S, the facing region 39, and the opening hole H in the same manner as in the above embodiment, and the viewer can visually recognize the light emitting design region 80. Similar effects can be obtained.

  Further, in the present embodiment, the example in which the light emitting design region 80 is provided in two places in the upper left portion and the upper right portion of the vehicle meter D in FIG. 1 is described, but any number of the light emitting design regions 80 may be formed. For example, as a second modification of the present embodiment, as shown in FIGS. 6 and 7, only one light emitting design region 80 is provided in the upper central region (or lower central region) of the vehicle meter D in FIG. Alternatively, three or more light emitting design regions 80 may be provided.

  As shown in FIGS. 6 and 7, when only one light emitting design region 80 is provided at the upper center of the vehicle meter D in FIG. 1, the shape of the opening 31 is not circular but rectangular. Is desirable. In addition, as an example of providing three or more light emitting design regions 80, for example, a configuration in which four light emitting design regions 80 are provided in the upper left portion, the upper right portion, the lower left portion, and the lower right portion of the vehicle instrument D in FIG. It is done.

  Further, in the present embodiment, when the fuel consumption state of the vehicle is good, the green colored light L emitted from the other pixels 70 strikes the pair of opposed regions 39, so that the vehicle meter in FIG. In the upper left part and the upper right part of D, an example in which the pair of light emitting design areas 80 are displayed in green is explained. For example, a pedestrian or the like seems to pass from the right side to the left side in front of the vehicle (own vehicle). In such a case, the light emitting design region 80 located in the upper right part of the vehicle meter D in FIG. 1 may be configured to emit light in yellow (or orange) instead of green.

  In this case, obstacle detection means (not shown) for detecting a target obstacle in front of the vehicle including the pedestrian or the like (front of the host vehicle) is provided, and the control unit 41 detects the obstacle detected by the obstacle detection means. When receiving information (for example, information indicating that a pedestrian is about to pass from the right side to the left side as described above), the other is located in the upper right part of the vehicle meter D in FIG. 1 based on the obstacle information. The display means 10 is operated so that yellow (or orange) colored light L is emitted from the 70 pixels of the pixel, whereby the light emitting design region 80 located in the upper right part of the vehicle meter D in FIG. The light is displayed.

  With this configuration, a viewer (driver) who visually recognizes the vehicle meter D has some obstacles in the vicinity of the host vehicle (vehicle) due to a change in the light emission color of the light emitting design region 80. It becomes possible to grasp this easily, and it becomes possible to improve alertness. In addition, when a pedestrian is about to pass from the right side to the left side in front of the vehicle, the light emitting design region 80 on the right side (upper right part) of the vehicle instrument D in FIG. (Orange) is light-emitting and displayed, so that there is an advantage that the direction in which an obstacle exists can be intuitively grasped.

  In this case, only the light emitting design region 80 may be provided in the upper central region (or the lower central region) of the vehicle instrument D in FIG. 1 as in the second modification. When the pedestrian is about to pass the front of the vehicle from the right side to the left side, the control unit 41 first sets the other pixel 70 so that the light emitting design area 80 displayed in yellow (or orange) is displayed only on the right end side. Then, another pixel 70 may be operated so that the light emitting design region 80 displayed on the right end side flows from the right end side to the left end side of the light emitting design region 80 with the passage of time. By being configured in this manner, the light emitting design area 80 is dynamically displayed following the movement of the pedestrian, so that a display device having a visual effect can be provided.

  Further, in the present embodiment, when the fuel consumption state of the vehicle is good, the green colored light L emitted from the other pixels 70 strikes the pair of opposed regions 39, so that the pair of light emitting design regions 80 is formed. Although an example of light emission display in green has been described, for example, as a third modification of the present embodiment, when the fuel consumption state of the vehicle is not good (that is, in the non-eco state), under the control of the control unit 41, The blue colored light L may be emitted from the other pixels 70, and thereby the pair of light emitting design areas 80 may be lit and displayed in blue.

  That is, this means that the control unit 41 receives an eco state signal (first state signal) indicating that the state of the vehicle is the eco state (first state), and is controlled by the control unit 41. In a situation where colored light L having green color (predetermined color) is emitted from the other pixels 70, the control unit 41 performs a second state in which the vehicle state is different from the first state (that is, the When a non-eco state signal (second state signal) indicating that the state is non-eco state) is received, another color (for example, blue) different from green (predetermined color) is selected based on the non-eco state signal. This means that the display unit 10 is operated so that other colored light (not shown) is emitted from the other pixels 70, so that the pair of light emitting design regions 80 are displayed in blue.

  That is, when the other colored light of blue emitted from the other pixel 70 hits the pair of opposing areas 39, the pair of light emitting design areas 80 is displayed in blue, and the viewer can see that the driving state of the vehicle is It can be easily recognized that the vehicle is not in an eco-driving state.

  Further, in the above-described third modified example, the light emission color of each light emitting design region 80 is changed (variable) based on whether the fuel consumption state of the vehicle is good or bad. For example, in the fuel consumption state of the vehicle, Instead, the light emission color of each light emitting design region 80 may be changed according to the driving mode of the vehicle.

  Specifically, for example, the control unit 41 receives a normal mode signal (first state signal) indicating that the vehicle state (driving mode) is a normal mode (first state), and is controlled by the control unit 41. Under the circumstances where, for example, colored light L having white (predetermined color) is emitted from the other pixels 70, the control unit 41 sets the vehicle state (driving mode) to the normal mode (first state). ) Is different from white (predetermined color) based on the sports mode signal when a sports mode signal (second state signal) indicating a second state (for example, sports mode) is received. Display means 10 is caused to perform display operation so that other colored light (not shown) having a different color (for example, red) is emitted from other pixels 70, whereby each light emitting design region 80 is displayed in red. In That.

  In this case, the viewer (driver) can appropriately select the normal mode or the sports mode by operating a driving mode conversion switch (not shown).

  As described above, according to the third modification of the present embodiment, the light emission color of the light emission design region 80 changes according to whether the fuel consumption state of the vehicle is good or not, so that the viewer (V There is an advantage that the driver can easily recognize whether or not the driving state of the vehicle is the eco-driving state based on the change in the light emission color of the light emitting design region 80. Similarly, since the light emission color of the light emitting design area 80 changes according to the driving mode, the viewer (driver) determines whether the driving state of the vehicle is the normal mode or the sports mode. There is an advantage that it can be easily recognized by the change of 80 emission colors.
