Abstract

A switching display (3) has a display plate (4), a dividing component (5) and a light source device (6). A translucent light guide component is not provided between the display plate (4) and the division component (5). A white color light from an indirect LED (61NR) is distributed through a lateral tube (51) to vertical tubes (50R, 50N) so that letter characters (43R, 42N) are illuminated by the light of the white color. A direct LED (63R) of orange color is placed in the vertical tube (50R). When an R mode is selected, the direct LED (63R) is turned on. The light of the direct LED (63R) illuminates a letter character (43R) directly, so that the one letter character (43R) is illuminated by the light of the orange color. An amount of the light of the orange color which leaks through the lateral tube (51) to the vertical tube (50N) is limited to a small amount. In addition, the light of the orange color that is leaking is weakened. As a result, the leakage of the light of orange color to the other letter character (42N) is reduced.

Description

The present invention relates to a display device according to which a display by an indirect lighting and a display by a direct lighting into each other.

A display device is known in the art, such as. B. in the Japanese Patent Publication No. 2004-233466 according to which a vehicle movement mode is displayed. According to the display device, a first illumination mode is switched to a second illumination mode, or vice versa, wherein a display character is illuminated with a common first color, while another display character is illuminated with a second color different from the usual first color. For example, white-colored light is used for the general first color, while orange-colored light or green-colored light is used for the second color. In addition, a plurality of display characters are arranged adjacent to each other. A light guide member is placed under the plurality of display characters so that light is guided from a light source of the first color to the plurality of display characters. The light guide member extends below and toward the plurality of display characters. Light sources of the second color are placed under the respective display characters.

The display device having the light guide member of the above prior art has a problem in that it needs a large number of parts and components. It also has a problem in that the cost of the display device is increased.

The display device of the above prior art has another problem in another view. For example, if one of the display characters is illuminated by the light from the second color light source, the light may pass through the light guide member to the adjacent display characters. A leakage of such light reduces a quality of lighting. Especially in a dark environment in the nighttime, it may be a problem that even a small leakage of the light can be detected by a user (a driver).

As in the above prior art ( JP 2004-233466 ), it is proposed to improve a shape of the light guide member to reduce the leakage of the light through the light guide member. However, this has a problem that the shape of the light guide member becomes complicated.

The present invention has been made in view of the above problems. It is an object of the present invention to provide a display device according to which a display is realized by an indirect lighting and a display by a direct lighting by a simple structure.

It is another object of the present invention to provide a display device according to which leakage of the light from one display character to another display character is reduced by a simple structure.

It is a further object of the present invention to provide a display device according to which, even in the case where a plurality of display characters are illuminated by a first light and one (or a few) of the display characters are detected by a second light different from the first light, is illuminated, the leakage of the second light to other display characters can be reduced by a simple structure.

The present invention has the following features to achieve the above objects.

According to a feature of the present invention, as defined, for example, in the appended claim 1, a display device is constructed of: a display plate (FIG. 4 ), which is a display character ( 40 ), which is illuminated by light from a rear side of the display panel ( 4 ) is to be illuminated; a light source device ( 6 ), which has a plurality of light sources, the light sources being an indirect light source ( 61NR . 61DF . 61BM . 61PF ) for indirect illumination of the display character ( 40 ) and a direct light source ( 63R . 62N . 62D . 62B . 62P ) for directly illuminating the display character ( 40 ) exhibit; and a partitioning component ( 5 ), which between the display plate ( 4 ) and the light source device ( 6 ) is provided.

In the above display device, the partitioning component has ( 5 ) a direct vertical tube or a direct vertical channel ( 50R . 50N . 50D . 50B . 50P ), which has an upper open end, which at a back side portion of the display character ( 40 . 43R . 42N . 42D . 42B . 42P ) and a lower open end, which is the direct light source ( 63R . 62N . 62D . 62B . 62P ), wherein the direct vertical tube defines a vertical through hole extending from the light source device (FIG. 6 ) in the direction of the display plate ( 4 ) extends; and
a lateral or lateral tube or a lateral or lateral channel ( 51 . 51NR . 51DF . 51BM . 51PF ), which has a lower open end, which the indirect light source ( 61NR . 61DF . 61BM . 61PF ), wherein the lateral tube ( 51 ) has a ceiling for shielding indirect light from the indirect light source in a vertical direction, and wherein the lateral tube ( 51 ) defines a recess portion which communicates with the vertical through-hole via a lateral connection aperture or connection aperture (Fig. 52R . 25N . 52D . 53F2 . 53M . 52B . 53F1 . 52P ), which in a partition wall between the direct vertical tube ( 50R . 50N . 50D . 50B . 50P ) and the lateral tube ( 51 . 51NR . 51DF . 51BM . 51PF ) at such a position close to the direct light source ( 63R . 62N . 62D . 62B . 62P ) of the direct vertical tube ( 50R . 50N . 50D . 50B . 50P ) is formed.

According to the above feature, the light of the indirect light source is reflected and scattered in the recess portion, and then provided to the vertical via hole via the connection aperture. As a result, the indirect illumination light reaches the display panel through the recess portion and the vertical through hole to display the display character. The light from the direct light source reaches the display panel through the vertical through hole to display the display character. As a result, it is possible to realize the display by the indirect illumination and the display by the direct illumination without providing the translucent light guide member between the display plate and the light source device.

According to another feature of the invention, as defined, for example, in appended claim 2, the display panel has ( 4 ) another display character ( 40 ), which is illuminated by the light from the back of the display panel ( 4 ) is to be illuminated. The division component ( 5 ) also points to another vertical pipe ( 50R . 50N . 50D . 50B . 50P . 50F . 50M ), which has an upper open end, which at a backside portion of the other indicator ( 40 . 43R . 42N . 42D . 42B . 42P ), wherein the other vertical tube defines another vertical through hole extending from the light source device (10). 6 ) in the direction of the display plate ( 4 ) extends; and the recess portion passing through the lateral tube (FIG. 51 . 51NR . 51DF . 51BM . 51PF ) is defined with the other vertical through hole via another lateral connection aperture ( 52R . 52N . 52D . 53F2 . 53M . 52B . 53F1 . 52P ), which in another partition wall between the other vertical tube ( 50R . 50N . 50D . 50B . 50P . 50F . 50M ) and the lateral tube ( 51 . 51NR . 51DF . 51BM . 51PF ) at such a position in the vicinity of the light source device ( 6 ) is formed.

According to the above feature, the light from the indirect light source is reflected and scattered in the recess portion and then provided to the other vertical pipe via the other connection aperture. As a result, the indirect illumination light reaches the display panel through the recess portion and the other vertical through hole to display the display character. The lateral tube is commonly used to realize the indication by the indirect illumination for the other indicator. In addition, the light of the direct light source is weakened when such light is transmitted from the vertical through hole to the other vertical through hole via the recess portion. As a result, the leakage of the light from the direct light source, which can be transmitted from one vertical through hole to the other vertical through hole, can be reduced.

According to a further feature of the invention, as defined, for example, in the appended claim 3, the light source device has ( 6 ) another direct light source ( 63R . 62N . 62D . 62B . 62P ) for directly illuminating the other display character ( 40 ), and the other vertical tube ( 50R . 50N . 50D . 50B . 50P ) has a lower open end, which is the other direct light source ( 63R . 62N . 62D . 62B . 62P ) surrounds.

According to the above feature, the light of the other direct light source reaches the display panel through the other vertical tube to illuminate the other display character. Accordingly, it is possible to realize the display by the indirect lighting and the display by the indirect lighting also for the other display sign. In addition, the light of the other direct light source is weakened when such light is transmitted from the other vertical through hole to the vertical through hole via the recess portion. As a result, the leakage of the light from the other direct light source, which can be transmitted from the other vertical through hole to the one vertical through hole, can be reduced.

According to a still further feature of the invention, as defined for example in the appended claim 4, the direct vertical tube (FIG. 50R . 50N . 50D . 50B . 50P ) and the other vertical tube ( 50R . 50N . 50D . 50B . 50P . 50F . 50M ) are arranged adjacent to each other and the lateral tube ( 51 ) is at lateral lateral portions of the direct vertical tube ( 50R . 50N . 50D . 50B . 50P ) and the other vertical tube ( 50R . 50N . 50D . 50B . 50P . 50F . 50M ) arranged.

According to such a feature, it is possible to have a light path along which the light from the one vertical through hole is extended to the other vertical through hole via the recess portion. As a result, the leakage of the light from the direct light source is reduced.

According to a still further feature of the invention, as defined for example in the appended claim 5, the direct vertical tube (FIG. 50R . 50N . 50D . 50B . 50P ) and the other vertical tube ( 50R . 50N . 50D . 50B . 50P . 50F . 50M ) are arranged adjacent to each other, and the lateral tube ( 51 ) is arranged such that the lateral tube ( 51 ) with each of the direct vertical tube ( 50R . 50N . 50D . 50B . 50P ) and the other vertical tube ( 50R . 50N . 50D . 50B . 50P . 50F . 50M ) overlaps in a vertical direction.

According to such a feature, the lateral tube can be arranged in a manner that the lateral tube does not project outwardly from the side portion of the vertical tubes.

According to a still further feature of the invention, as defined for example in the appended claim 6, the light source device has ( 6 ) a printed circuit board ( 64 ) on which a plurality of light emitting diodes (LEDs) are mounted, the light emitting diodes being used as the light sources. In addition, the splitting component ( 5 ) on the printed circuit board ( 64 ), wherein the lateral connection aperture in the partition wall of the splitting component ( 5 ) is formed between the vertical tube and the lateral tube, and wherein a height (HD) of a light emitting surface of the light emitting diode from a surface of the printed circuit board is almost equal to a height (HW) of the lateral connection aperture from the surface of the printed circuit board.

According to such a feature, it is suppressed that the light of the diode from the direct light source directly reaches the connection aperture. As a result, the leakage of the light from the direct light source into the recess portion can be reduced.

According to a still further feature of the invention, as defined for example in the appended claim 7, a brightness of the indirect light source is higher than a brightness of the direct light source.

According to such a feature, since the indirect light source displays the display characters by the indirect illumination, it can be avoided that the display characters are displayed with excessively bright illumination. On the other hand, the direct light source indicates the display characters by the direct illumination. Thus, the display characters can be displayed with a necessary brightness even if the direct light source has a lower brightness. Furthermore, the leakage of the light from the direct light source can be reduced because the brightness of the direct light source is made smaller.

First Embodiment

1 FIG. 10 is a schematic plan view showing an instrument device according to a first embodiment of the present invention. FIG. The instrument device 1 is a display device mounted in a vehicle. The vehicle is, for example, a hybrid vehicle that is driven by an internal combustion engine and / or an electric motor.

The vehicle has a selector device 2 which selects one of the vehicle operating modes. When selecting the operating mode, a single operating mode or a combination of several operating modes can be selected. The plurality of operation modes include an R mode in which the vehicle is moved in a rearward direction, an N mode in which a drive system and a power source are separated from each other, a D mode in which the vehicle is in one forward direction, a B mode in which an amount of regenerated electric power is increased during vehicle speed reduction when the vehicle is in the D mode and a P mode in which the vehicle is parked, one.

The selection device 2 has a gear lever 21 , which is operated by a driver. The shift lever allows the driver to select the R mode, the N mode, the D mode, and the B mode. The B mode is a combination mode that can be selected only when the vehicle is in the D mode. The selection device 2 also has a parking brake device 22 , The B mode is selected when the parking brake device 22 operated or operated. In addition, the selector has 2 an electronic control unit 23 , which signals for operating states of the shift lever 21 and the parking brake device 22 and from which signals are output according to the selected operating mode. The output signals control a light ON state and a light OFF state of a plurality of light sources, as explained below.

The instrument device 1 has a switch indicator 3 , which is a display device of the invention. The shift indicator 3 shows the selected mode of operation depending on the output signals from the selector 2 at.

2 is a schematic plan view showing the shift indicator 3 shows which is the display device according to the first embodiment of the invention. Several display characters 40 are on or on or in a display panel 4 the shift indicator 3 educated. The display plate 4 has a translucent resin plate formed of an acrylic resin, a polycarbonate resin, etc., and a printed layer printed on a front or a rear surface of the resin plate. The multiple display characters 40 are formed by the printed layer. The printed layer has a portion of black ink formed by a light-shielding ink and non-printed or translucent portions. The non-printed or translucent sections have shapes corresponding to the respective indicia. Fine concavo-convex portions are on the non-printed or translucent sections of the display plate 4 formed to realize a uniform brightness by scattering light. The fine concavo-convex portions are pinned surfaces.

Illuminating light passes through each of the display characters 40 when the display panel 4 is illuminated from its back, leaving the indicator 40 are lit or illuminated (a Display state). The display state for one or some of the display characters is changed from a first display state (in which existence of the display character is displayed) to a second display state (in which a selection of an operation mode indicated by such a lit display character is displayed).

An illumination mode is changed by changing the characteristics of the illumination light. More specifically, a turn-on state of a light having a first characteristic and a light having a second characteristic are changed from one to the other. The light having the first characteristic and the light having the second characteristic are different from each other so that the user can recognize a difference between them.

With respect to the light having the first characteristic, light of a first color is used as a background color. The first color is white. The first color is also referred to as the background color since the first color light is used as a background for the plurality of display characters, or because the first color is a common color for the plurality of display characters. The illumination by the light of white color is made for the purpose of allowing the user to recognize the existence (the placement) of the plurality of display characters.

Light of a second color is used as the light having the second characteristic, so that the selected operating mode can be visually recognized as the operating mode which is different and different from the other operating modes. The second color is different from the first color. For example, the second color is an orange or green color. The second color light is directed only in the direction of the display character corresponding to the selected operation mode, so that the second color light is provided to the display character in addition to the first color light. The second color is a color for the purpose of one (or a few) of the display characters most highly on the display 3 to make visible. The second color is also referred to as a display color or a particular color.

Several display characters 40 have operating signs 41F and 41M , which is a mode of operation or an operating direction of the shift lever 21 Show, and letters 43R . 42N . 42D . 42B and 42P which indicate multiple vehicle operating modes.

On the operating sign 41F is also referred to as the first operating sign. The operating sign 41F has a circular mark, which is a starting position of the shift lever 21 indicating and several (three) arrow signs showing the operating directions of the shift lever 21 indicate positions to the R mode, the N mode and the D mode. The operating sign 41M , which is also referred to as a second operation mark, has an arrow sign indicating the operation direction in the B mode position.

On the letters ( 43R . 42N . 42D . 42B and 42P ) is also referred to as an operation mode flag. For example, the letter is 42P , which indicates the P-mode, composed of a character "P" and a frame. On the letters 43R . 42N . 42D and 42P is also referred to as the first operating mode character while pointing to the character 42B also referred to as a second mode flag.

During a period in which a circuit breaker of the vehicle is turned on, both the operating sign 41F as well as the letters 43R . 42N . 42D and 42P indicated by illuminating the white-colored light. On the operating sign 41F is also referred to as a first monochrome sign which is illuminated only by the light of white color during the period in which the power switch of the vehicle is turned on. Because the operating sign 41F and the letters 43R . 42N . 42D and 42P illuminated by the light of white color (ie, a light of a first color), these characters form ( 41F . 43R . 42N . 42D and 42P ) a first set of characters which is illuminated by the light of the first color during the period in which the power switch of the vehicle is turned on.

According to the present embodiment, a direct vertical pipe ( 50R . 50N . 50D . 50B . 50P ) provides a direct illumination light passage through which the second color light can pass from the direct light source (the direct LED) and can directly reach the display character. In addition, a direct vertical pipe and a lateral pipe provide the indirect illumination light passage in which the light of the first color is reflected and scattered by the indirect light source (the indirect LED) and then indirectly reaches the display character. Thus, the direct illumination light passage provides a portion of the indirect illumination light passage.

The indirect illumination light passage is connected to the direct illumination light passage at a lower portion thereof (the lateral connection aperture), so that the first color light from the indirect illumination light passage is provided to the direct illumination light passage through such a lower portion.

In addition, the recess portion of a lateral pipe is connected to a plurality of vertical through holes formed by the vertical pipes including at least one direct vertical pipe. As a result, a lateral tube provides the light of the first color to the plurality of vertical tubes.

In addition, a direct vertical tube and an indirect vertical tube may be included in the plurality of vertical tubes into which the first color light from a lateral tube is provided.

In the 2 and 3 is when the multiple display characters 40 illuminated by the light of white color, the brightness of the display characters 40 about 20 cd / m ² . On the other hand, if the letters are 43R . 42N . 42D and 42P illuminated by the light of orange color or green color, the brightness of the characters about 200 cd / m ² . As described above, the character ( 43R . 42N . 42D and 42P ), which corresponds to the selected vehicle operating mode, lit brighter than the backlight of the white color. And the character is displayed with the light of the second color different from the background color.

The light of white color from the indirect LED ( 61NR . 61DF . 61BM and 61PF ) is in the lateral tube 51 ( 51NR . 51DF . 51BM . 51PF ) diffusely reflects and then reaches the corresponding display character 40 ( 43R . 42N . 42D . 42B . 42P . 41F and 41M ). On the other hand, the light reaches the orange color or the green color of the direct LED ( 63R . 62N . 62D . 62B and 62P ) directly the corresponding display character 40 , The brightness for the indirect LEDs 61NR . 61DF . 61BM and 61PF is higher than the brightness for the direct LEDs 63R . 62N . 62D . 62B and 62P in view of the differences of the above light paths. As a result, even if the light from the indirect LEDs diffuses through the splitting member 5 and the printed circuit board 64 is reflected, a necessary brightness for the display panel can be achieved or obtained. In contrast, it can be avoided that the display characters are illuminated with excessively high brightness. In addition, it is possible to adjust the brightness for the direct LEDs 63R . 62N . 62D . 62B and 62P to suppress. The brightness of the respective LEDs 60 (the direct LEDs and the indirect LEDs) is adjusted by controlling the electric current provided to the LEDs, so that the necessary brightness on the display panel 4 can be obtained.

The control unit 23 switches the indirect LEDs 61NR . 61DF and 61PF during the period in which the on state of the Circuit breaker of the vehicle is maintained continuously. As a result, the existence (placement) of the display characters for the vehicle operating modes, which can be selected by the driver, as well as the operating directions of the shift lever 21 displayed. When one of the vehicle operating modes by the shift lever 21 or the parking brake device or parking brake device 22 is selected, the control unit turns off 23 one of the direct LEDs 63R . 62N . 62D . 62B and 62P which corresponds to the corresponding operating mode.

For example, the control unit switches 23 the direct LED 63R for the orange color light, only on when the R mode is selected. The control unit 23 turns on the direct LED 62N for the light of green color, only when N mode is selected. The control unit 23 turns on the direct LED 62D for the light of green color, only when D mode is selected. The control unit 23 turns on the direct LED 62P for the light of green color, only when P mode is selected. The control unit 23 turns on the indirect LED 61BM only on if D-mode is selected. In addition, the control unit switches 23 the direct LED 62B for the light of the green color, only when the B mode is selected while the D mode is selected.
