Referring to fig. 1 and 2, the present invention relates to a three-dimensional instrument cluster (hereinafter referred to as "cluster panel"), which includes a first display screen 1, a second display screen 2 and a glass plate 3, wherein a display surface 11 of the first display screen and a display surface 21 of the second display screen are arranged at an included angle, the glass plate 3 is arranged in the included angle between the first display screen 1 and the second display screen 2, the glass plate 3 has a front surface and a back surface which are almost parallel to each other, the display surface 11 of the first display screen faces the front surface of the glass plate 3, the display surface 21 of the second display screen faces the back surface of the glass plate 3, so that the display surface 11 of the first display screen forms a mirror image display surface 12 located on the back surface of the glass plate 3 by using the front surface of the glass plate 3 as a reflector, the mirror image display surface 12 is located on the front side or the back side of the display surface 21 of the second display screen, and is substantially parallel to the display surface 21 of the second display screen, and preferably, the mirror image display surface 12 is parallel to the display surface 21 of the second display screen, but considering the assembling process and the error, the mirror image display surface 12 may be substantially parallel to the display surface 21 of the second display screen, and the substantially parallel may be: the angle between the plane of the mirror image display surface 12 and the plane of the display surface 21 of the second display screen is within 10 deg.. The first display screen 1 is used for displaying a first image, the first image is located on the display surface 11 of the first display screen, the second display screen 2 is used for displaying a second image, the second image is located on the display surface 21 of the second display screen, the projection of the mirror image display surface 12 on the surface of the display surface 21 of the second display screen is partially or completely overlapped with the display surface 21 of the second display screen, the front surface of the glass plate 3 has light reflecting properties, so that a virtual image formed by the front surface of the glass plate 3 as a reflecting mirror of the first image is located on the back surface of the glass plate 3 and is visible on the mirror image display surface 12 at the front side of the glass plate 3, the back surface of the glass plate 3 has light transmitting properties, and the second image is located on the display surface 21 of the second display screen, so that the second image is visible at the front side of the glass plate, when a driver looks at the virtual image and the second image, from the view angle of the driver, the virtual image and the second image are concentrated in the same area, so that a driver generates an illusion that the virtual image and the second image are generated by the same display screen, and the virtual image and the second image have a distance in the front-rear direction, so that the driver generates a combined image which is displayed by one display screen and has a depth in the front-rear direction at the same time, so that the virtual image and the second image form a combined image with a stereoscopic effect; one of the first display screen 1 and the second display screen 2 is a segment code screen 4, the other display screen is a dot matrix color display screen 5, the three-dimensional instrument cluster further includes a first control unit (not shown in the figure) for controlling the segment code screen 4 and a second control unit (not shown in the figure) for controlling the dot matrix color display screen 5, wherein the first control unit is configured to control a plurality of controllable display areas 41 (see fig. 3, except for an outer contour of the segment code screen, all patterns in fig. 3 are controllable display areas 41) of the segment code screen 4 according to received input information to perform display or stop display (after the display is stopped, an image displayed by the controllable display area cannot be seen, for example, fig. 13 shows only a part of the controllable display areas which can be seen by human eyes with respect to fig. 3, and the part which cannot be seen is in a stop display state), the second control unit is used for controlling the dot matrix type color display screen 5 to display and change display contents according to the received input information.

Referring to fig. 3, the segment code screen 4 has the following advantages over the dot matrix color display screen 5: the manufacturing cost is low; accordingly, the segment code screen 4 can display only relatively fixed contents. Specifically, the segment code screen 4 has a plurality of controllable display areas 41, each controllable display area 41 can be controlled individually (the controllable display areas 41 can be switched between displaying and stopping displaying), the controllable display areas 41 can be designed into different shapes (planar states) according to requirements, the first control unit controls part or all of the controllable display areas 41 to be lighted (displayed) according to input information received by the first control unit, each controllable display area 41 can form a controllable display area pattern (the same shape as the controllable display area 41) after being lighted, the controllable display area patterns can form one or more display patterns (the display patterns include digital patterns, alarm lamp patterns and the like), some display patterns are one controllable display area 41 pattern (such as alarm lamp patterns), some display patterns are formed by a plurality of controllable display area 41 patterns (such as digital patterns), these display patterns on the segment code screen 4 together form the image displayed on the display surface of the segment code screen 4. Since the position and shape of each controllable display area 41 are fixed, the controllable display area 41 forms a pattern of controllable display areas 41 that is fixed (the shape, position, and size are fixed with respect to the display surface of the segment code screen 4) when lit, and the controllable display areas 41 do not form a pattern of controllable display areas when the controllable display areas 41 are not lit (display is stopped). Thus, the segment code screen 4 presents an image in operation in which a number of lit (displayed) controllable display area patterns are distributed on a black background, and the segment code screen 4 controls the lit controllable display area patterns to be turned off (stopped from being displayed) and the unlit (stopped from being displayed) controllable display areas 41 to be turned on (displayed) according to input information actually received by the segment code screen 4, thereby changing the displayed pattern on the image.

Referring to fig. 4, the dot matrix color display screen 5 is different from the segment code screen 4, the manufacturing cost is higher than that of the segment code screen 4, and the color of any pixel point on the display surface of the dot matrix color display screen 5 can be changed arbitrarily, so that any pattern can be displayed on the display surface of the dot matrix color display screen 5, that is, the pattern displayed by the dot matrix color display screen 5 is not limited by color and shape, or the pattern is not displayed in the local area (black) in the display surface of the dot matrix color display part, and the patterns are displayed in other parts.

For convenience of description, the first display screen 1 is used as a segment code screen 4, and the second display screen is used as a dot matrix color display screen 5 for explanation.

The segment code screen 4 is formed by a virtual image formed by reflection of the front surface of the glass plate 3 in an illuminated state, which is composed of a plurality of display patterns each composed of one or more controllable display area patterns, the second display screen 2 is formed as a second image when illuminated, and when the instrument cluster is mounted on the instrument desk, the driver sits on the main driver's seat with his line of sight substantially directed towards the second image, and the combined image seen by the driver, with a plurality of display patterns (corresponding virtual images) distributed over the second image, since the mirror image display surface 12 is located on the front or rear side of the display surface 21 of the second display screen, the virtual image is located on the front or rear side of the second image, at the same time, the pattern on the second image is designed to make the second image match with the display pattern, therefore, the virtual image and the combined image formed by the second image are more consistent, and the three-dimensional effect of the combined image is enhanced.

In addition, the dot matrix color display screen 5 can display any pattern, and thus the second image displayed by the dot matrix color display screen 5 can be a dynamic image, and in the combined image formed by combining the dynamic second image and the static virtual image, because the second image is dynamic, the whole combined image looks dynamic, so that the dynamic effect of the combined image is enhanced. Further, the virtual image and the second image are substantially concentrated on the same area, and the virtual image is substantially parallel to the second image, so that the driver creates an illusion that both the virtual image and the second image are displayed on one display screen, thereby enhancing the stereoscopic effect of the combined image.

In a preferred embodiment, referring to fig. 3 and 4, the plurality of controllable display areas 41 of the segment code screen 4 are at least used for displaying first digital information (corresponding to a display pattern, see fig. 3, which is formed when a part or all of the controllable display areas 41 in the first controllable display area group 42 are displayed) and second digital information (corresponding to a display pattern, see fig. 3, which is formed when a part or all of the controllable display areas 41 in the controllable display area group 43 are displayed); the dot matrix color display screen 5 is at least used for displaying a background image or background animation 53, a first black area 51 and a second black area 52 are arranged in the background image or background animation 53, the colors displayed by the first black area 51 and the second black area 52 are pure black, in the combined image, the first digital information corresponds to the first black area 51, and the second digital information corresponds to the second black area 52; the first digital information is vehicle speed information, and the second digital information comprises engine speed information, electric quantity information, remaining mileage information or output power information.

The automobile meter has the main function of displaying information of the vehicle, such as vehicle speed, engine speed, oil quantity, water temperature and the like.

For fuel vehicles and hybrid vehicles, the vehicle speed and the engine speed are the most important two pieces of information during the driving of the vehicle, and both pieces of information can be represented by numbers. The segment code screen 4 is relatively easy to implement digital pattern display, so that the segment code screen 4 can be used for displaying the vehicle speed and the engine speed, namely, the first digital information and the second digital information. When the segment code screen 4 displays the first digital information and the second digital information, the display pattern corresponding to the first digital information and the display pattern corresponding to the second digital information are respectively formed by cooperatively displaying the plurality of controllable display areas 41, so that the display patterns in different digital styles are combined by partially or completely displaying the plurality of controllable display areas 41 (see fig. 10, 11 and 12).

In the combined image, the first digital information corresponds to the first black region 51, and the second digital information corresponds to the second black region 52, which means that: the projection of the first digital information on the plane where the first black area 51 is located, is located within the first black area 51; similarly, the projection of the second digital information onto the plane of the second black area 52 is located within the second black area 52. Therefore, at the view angle of the driver, the peripheries of the first digital information and the second digital information are both black, so that the driver can distinguish the specific numerical values of the first digital information and the second digital information more easily, and can know the current vehicle speed and the current engine speed more conveniently.

The dot matrix color display panel 5 is used to display a background image or a background animation 53, for example, taking the background image as an example, the background image is displayed on the whole display surface of the dot matrix color display panel 5 without considering the first black area 51 and the second black area 52, and on this basis, the first black area 51 and the second black area 52 of the dot matrix color display panel 5 display black (do not emit visible light or emit visible light with low brightness), which is equivalent to drawing out two independent black areas on the background image. Similarly, when the background animation is displayed on the display surface of the dot-matrix color display screen 5, it is equivalent to two independent black areas on the background animation. The position and size of the two independent black areas are always fixed relative to the position of the display surface of the dot matrix color display screen 5.

In addition, in the case of the pure electric vehicle, since the pure electric vehicle does not have an engine, the second digital information is not engine speed information, and output power information of the motor, remaining mileage information (remaining mileage allowed information), remaining energy information, and the like (which is specific to the second digital information, which may be preset or set by the driver) may be generally displayed.

In some preferred embodiments, referring to fig. 5, the dot matrix color display screen 5 is further configured to display a first dial pattern 54 and a second dial pattern 55, the first dial pattern 54 is located at the periphery of the first black area 51, and the second dial pattern 55 is located at the periphery of the second black area 52. The second image additionally displays a first dial pattern 54 and a second dial pattern 55 on the basis of displaying a background image or background animation 53. Taking a fuel vehicle as an example, in the combined image, the display pattern corresponding to the first digital information and the first dial pattern 54 together form a speedometer image; the second digital information and the second dial pattern 55 together form a tachometer image, so that the style of the tachometer is basically the same as that of the conventional speedometer and tachometer, and a driver can easily understand the information displayed in the combined image.

Preferably, the style of the first dial pattern 54 and the second dial pattern 55 may be preset in various ways, and the driver may select the style of the first dial pattern 54 and the second dial pattern 55 according to personal preference.

In some preferred embodiments, referring to fig. 6, the plurality of controllable display areas 41 of the segment code screen 4 are further configured to display a third dial pattern (a display pattern, see the pattern formed when the third controllable display area group 44 in fig. 6 is displayed) located at the periphery of the first digital information (see the pattern formed when the first controllable display area group 42 in fig. 6 is displayed) and a fourth dial pattern (a display pattern, see the pattern formed when the controllable display area group 45 corresponding to the fourth dial pattern in fig. 6 is displayed) located at the periphery of the second digital information (see the pattern formed when the controllable display area group 43 corresponding to the second digital information in fig. 6 is displayed); in the combined image, the third dial pattern constitutes the dial of the first digital information together with the first dial pattern 54 (see fig. 7), and the fourth dial pattern constitutes the dial of the second digital information together with the second dial pattern 55 (see fig. 7).

Referring to fig. 7, taking the first display screen 1 as the segment code screen 4 and the second display screen 2 as the dot matrix color display screen 5 as an example, the virtual image displays a display pattern corresponding to the first digital information, a display pattern corresponding to the second digital information, a third dial pattern and a fourth dial pattern; a background image or background animation 53, a first dial design 54 and a second dial design 55 are displayed on the second image. Taking a fuel vehicle as an example, in the combined image, the display pattern corresponding to the first digital information, the first dial plate pattern 54 and the third dial plate pattern together form a speedometer image; the display pattern corresponding to the second digital information, the second dial pattern 55 and the fourth dial pattern together constitute an engine tachometer image.

In the aforementioned vehicle speed meter image, the first dial pattern 54 is displayed by the second image, and the third dial pattern is displayed by a virtual image, so that the first dial pattern 54 and the third dial pattern have a depth in the front-rear direction, and the projection of the third dial pattern on the second image is close to, partially or completely overlapped with the pattern of the first dial, so that the combination of the first dial pattern 54 and the third dial pattern seen by the driver forms the dial pattern of the first digital information, and the dial pattern is a three-dimensional style dial pattern. Likewise, the second dial pattern 55 and the fourth dial pattern can also form a stereo style dial pattern.

It will be appreciated that the third dial pattern and the fourth dial pattern are of a fixed pattern (shown by the segment code screen 4) and that the first dial pattern 54 and the second dial pattern 55 are of a variety of patterns, wherein one of the first dial patterns 54 is capable of matching with the third dial pattern and one of the second dial patterns 55 is capable of matching with the fourth dial pattern. Thus, when the third dial pattern and the fourth dial pattern are lighted, the first dial pattern 54 and the second dial pattern 55 both display a pattern matching therewith, and when the third dial pattern and the fourth dial pattern are not lighted, the first dial pattern 54 and the second dial pattern 55 can select any one of the patterns to display according to the selection of the driver, so as to increase the selectable range of the dial patterns.

In a preferred embodiment, referring to fig. 6, each of the third dial plate pattern and the fourth dial plate pattern is composed of a plurality of controllable display areas 41 arranged along a circumference, and the first control unit controls a part of the controllable display areas 41 to display according to a preset corresponding relationship, so that the circumference length of the illuminated third dial plate pattern matches with the size of the first digital information, and the circumference length of the illuminated fourth dial plate pattern matches with the size of the second digital information.

Taking the first digital information as an example, on the segment code screen 4, the controllable display area 41 corresponding to the first digital information is a first controllable display area group 42, a third controllable display area group 44 is arranged at the periphery of the first controllable display area group 42, the third controllable display area group 44 includes a plurality of circularly arranged dial controllable display areas 441, the third controllable display area group 44 is in a fan-ring shape, and in the driving process of the automobile, the first control unit receives a vehicle speed signal and controls part or all of the controllable display areas 41 in the first controllable display area group 42 to display a specific vehicle speed value (display pattern) according to the vehicle speed signal; the first control unit further controls a part or all of the dial controllable display areas 441 in the third controllable display area group 44 to display according to the vehicle speed signal, and when the third controllable display area group 44 displays, the dial controllable display areas 441 are sequentially displayed counterclockwise according to the vehicle speed signal, so that the dial controllable display areas 441 in the third controllable display area group 44 are more lighted as the vehicle speed is higher, and the circumferential length of the displayed third dial pattern is longer. Similarly, the length of the illuminated circle of the fourth dial pattern is positively correlated with the value of the second digital information.

In another preferred embodiment, referring to fig. 8, the plurality of controllable display areas 41 of the segment code screen 4 are further configured to display a first pattern (a pattern formed when the first pattern controllable display area group 46 is displayed) and a second pattern (a pattern formed when the second pattern controllable display area group 47 is displayed), wherein the first pattern and the second pattern are both fan-shaped, an arc length of the first pattern corresponds to a value of the first digital information, and an arc length of the second pattern corresponds to a value of the second digital information; in the combined image, a projection of the first pattern on a plane where the first black region 51 is located in the first black region 51, and in the combined image, a projection of the second pattern on a plane where the second black region 52 is located in the second black region 52.

Referring to fig. 8, the plurality of controllable display regions 41 of the segment code screen 4 include a first pattern controllable display region group 46 and a second pattern controllable display region group 47, the first pattern controllable display region group 46 includes a plurality of first pattern controllable display regions 461, the second pattern controllable display region group 47 includes a plurality of second pattern controllable display regions 471, the plurality of first pattern controllable display regions 461 are sequentially arranged around the first digital information, and the plurality of second pattern controllable display regions 471 are sequentially arranged around the second digital information. During the running process of the automobile, the first control unit receives a speed signal and controls part or all of the controllable display areas 41 in the first controllable display area group 42 to display according to the speed signal so as to display a specific speed value; the first control unit further controls a part or all of the first pattern controllable display regions 461 in the plurality of first pattern controllable display regions 461 to display according to the vehicle speed signal, and when the first pattern controllable display region group 46 displays, the first pattern controllable display regions are displayed in a counterclockwise sequence according to the vehicle speed signal, that is: the higher the vehicle speed, the more the first pattern controllable display regions 461 within the first pattern controllable display region group 46 are illuminated, and the longer the arc length of the first pattern displayed. Similarly, the arc length of the second pattern that is illuminated is positively correlated with the value of the second digital information.

In addition, when the driver views the combined image, the first pattern is located in the first black area 51, so that the driver can easily recognize the first pattern in the combined image, thereby knowing the vehicle speed of the vehicle. Similarly, for the fuel vehicle, the driver can easily distinguish the second pattern in the combined image, so as to know the engine speed.

Furthermore, the first pattern is located at the periphery of the first digital information, the second pattern is located at the periphery of the second digital information, the center of the circle of the first pattern is located at the first digital information, and the center of the circle of the second pattern is located at the second digital information. The first pattern is adjacent to the first digital information and is positioned in the first black area 51, the second pattern is adjacent to the second digital information and is positioned in the second black area 52, in addition, the arc length of the first pattern is related to the numerical value of the first digital information, and the arc length of the second pattern is related to the numerical value of the second digital information, so that a driver can conveniently see the first pattern when looking over the first digital information, and the driving speed of the automobile can be intuitively known; when the driver views the second digital information, the driver can conveniently see the second pattern, so that the engine speed (for a fuel vehicle) of the automobile can be intuitively known.

In a preferred embodiment, see fig. 9-12, diagonal fill represents green and solid fill represents red in the four figures. The plurality of controllable display areas 41 corresponding to the first pattern are divided into a first area group 462 and a second area group 463, the head end of the second area group 463 is adjacent to the tail end of the first area group 462 and forms an unclosed fan ring shape together, when the vehicle speed is increased from 0, the first controllable display area 41 at the head end of the second area group 463 is displayed in sequence (anticlockwise or clockwise) from the controllable display area 41 at the head section of the first area group 462 to the tail end of the first area group 462 (see fig. 10), when the vehicle speed reaches 120km/h, the first controllable display area 41 at the head end of the second area group 463 is displayed (see fig. 11), and as the numerical value of the vehicle speed is increased, the controllable display areas 41 in the second area group 463 are displayed in sequence from the head end to the tail end (see fig. 12), the controllable display areas 41 in the first area group are displayed in green, and the controllable display areas 41 in the second area group are displayed in red.

All the first pattern controllable display regions 461 in the first pattern controllable display region group 46 are sequentially arranged to form an unclosed ring, and the unclosed ring is sequentially lighted (e.g., counterclockwise) from one first pattern controllable display region 461 at one end according to the actual speed of the vehicle during the traveling from a standstill to a high speed. For example, when the vehicle speed is 5km/h, the first pattern controllable display area 461 is lighted, when the vehicle speed is 10km/h, the first and second first pattern controllable display areas 461 are lighted, and so on, when the vehicle speed reaches 115km/h, there are twenty-three first pattern controllable display areas 461 that are lighted in succession, and the colors of the twenty-three lighted first pattern controllable display areas 461 may be the same (e.g., green), and when the vehicle speed reaches 120km/h (see fig. 11), the twenty-fourth first pattern controllable display area 461 is lighted, but the twenty-fourth first pattern controllable display area 461 is lighted in red, thereby alerting the driver that there is a risk of speeding, and when the vehicle speed exceeds 120km/h, the controllable display areas 41 in the second area group 463 are displayed in order from the head end to the tail end thereof (see fig. 12), that is, the portion exceeding 120km/h is displayed in red color, and the driver is notified that the speed has been exceeded (taking the speed limit of the expressway at 120km/h as an example).

Similarly, referring to fig. 13, each of the second pattern controllable display areas 471 represents 250r/min, and at the front side, 25 second pattern controllable display areas 471 (corresponding to the engine speed lower than 6250r/min) are provided, the color of the second pattern controllable display area 471 may be green or white in the lighting condition, and the color of the second pattern controllable display area 471 which is lighted backwards (corresponding to the engine speed higher than 6500 r/min) is red, so as to remind the driver that the engine speed is too high.

In a preferred embodiment, the plurality of controllable display areas 41 of the segment code screen 4 are further configured to display at least a part of a plurality of indicator light information (a display pattern), where the plurality of indicator light information includes a front fog light, a lighting lamp, a high beam light, a low tire pressure warning light, a left turn light 49, a right turn light, a seat belt warning light, an engine failure light, a cruise control indicator light, and the like, and a projection of part or all of the plurality of indicator light information in the combined image on a plane where the first black area 51 is located in the first black area 51 or the second black area 52; the projection of the remaining part of the indicator light information in the combined image on the plane where the first black region 51 is located outside the first black region 51 and the second black region 52.

Taking a fuel vehicle as an example, the combination instrument panel is not only used for displaying vehicle speed information and transmitter rotating speed information, but also used for displaying indicator light information, and preferably, all the indicator light information is displayed by the segment code screen 4; or, part of the indicator light information is displayed by the segment code screen 4, and the rest of the indicator light information is displayed by the dot matrix color display screen 5. Referring to fig. 13, taking a left turn as an example, the driver toggles the steering lever to the left, and the first control unit receives the left turn control signal, and then controls the left turn lamp 49 on the segment code screen 4 to flash (the controllable display area 41 corresponding to the left turn lamp 49 switches back and forth between displaying and stopping displaying).

For convenience of description, for "the projection of part or all of the plurality of indicator light information in the combined image on the plane where the first black region 51 is located" is located in the first black region 51 or the second black region 52, it is referred to as "the part or all of the indicator light information is located in the first black region 51 or the second black region 52", and for "the projection of the remaining part of the indicator light information in the combined image on the plane where the first black region 51 is located, it is referred to as" the remaining part of the indicator light information is located outside the first black region 51 and the second black region 52 ".

If all the indicator light information is displayed by the segment code screen 4, the front fog light, the illuminating light, the high beam light, the left turn light 49, the right turn light and the cruise control indicator light are positioned outside the first black area 51 and the second black area 52; the tire pressure low warning lamp, the seatbelt reminder lamp, and the engine failure lamp are located in the first black region 51 or the second black region 52.

If some indicator light information is displayed by the segment code screen 4, another part of indicator light information is displayed by the dot matrix type color display screen 5, the indicator light information in the first black area 51 or the second black area 52 is completely displayed by the segment code screen 4, and the part or the whole indicator light information outside the first black area 51 and the second black area 52 can be displayed by the dot matrix type color display screen 5.

In the case of the indicator information other than the first black area 51 and the second black area 52, taking the left turn lamp 49 as an example, the left turn lamp 49 is displayed by the segment screen 4, and in the combined image, the entire left turn lamp 49 is partially overlapped with the background image or background animation 53 displayed on the dot matrix color display screen 5, and in this case, in order to ensure the clarity of the left turn lamp 49, it is preferable that the image displayed on the segment screen 4 is positioned on the front side of the image displayed on the dot matrix color display screen 5.

If the left turn light 49 is displayed by the dot matrix color display 5, the dot matrix color display 5 may directly superimpose and display the pattern of the left turn light 49 on the original background image or background animation 53.

In some preferred embodiments, referring to fig. 14, the projection of the remaining part of the indicator light information in the combined image on the plane where the first black area is located is an indicator light projection area, and when at least one of the remaining part of the indicator light information is turned on, the part of the image displayed on the dot-matrix color display screen 5 corresponding to the indicator light projection area is turned black; the area of the blackened area (i.e., the black spot area 56) corresponding to the projection area of the indicator lamp in the image displayed on the dot matrix color display screen 5 is 1.5-3 times the area of the projection area of the indicator lamp.

As for the indicator information outside the first black region 51 and the second black region 52, since the indicator information area is small, and the part of the indicator light information is interfered by the background image or background animation 53 displayed by the dot-matrix color display screen 5, so that the driver can not effectively and quickly distinguish whether the indicator light information is displayed, thus, after a certain indicator light information (one indicator light information other than the first black area 51 and the second black area 52) is turned on (displayed), the corresponding area on the background image or background animation 53 displayed on the dot-matrix color display screen 5 is blackened, thus, when viewing the combined image, the driver will see a distinct dark spot area 56 on the background image or background animation 53, and an indicator light message is displayed at the black spot area 56 so that the driver can clearly understand and grasp the condition of the automobile.

Referring to fig. 13 and 14, taking the left turn light 49 displayed on the segment code screen 4 as an example, the driver dials the steering lever to the left, the first control unit and the second control unit can both receive the left turn control signal, the first control unit controls the left turn light 49 on the segment code screen 4 to flash, and the second control unit controls the corresponding area of the dot matrix color display screen 5 to be black to form a black spot area 56, so that the driver can see that the left turn light 49 flashes at one black spot area 56 in the combined image (see fig. 15).

Referring to fig. 16 and 17, if the dot matrix color display 5 displays a left turn light pattern, the driver dials the steering lever to the left, the second control unit receives the control signal of the left turn light 49, the second control unit controls the dot matrix color display 5 to display the left turn light pattern (including the left turn light 49 and a black spot area 56 around the left turn light 49) outside the first black area 51 and the second black area 52, and the left turn light pattern covers the original background image or background animation 53.

The blackened area corresponding to the projection area of the indicator lamp in the image displayed on the dot-matrix color display screen 5 is the aforementioned black spot area 56, and the area of the black spot area 56 is 1.5-3 times the area of the projection area of the indicator lamp. Obviously, the area of the black spot region 56 is significantly larger than that of the indicator light, so in the combined image, from the perspective of the driver, when some indicator light information (outside the first black region 51 and the second black region 52) is displayed, the black spot region 56 is synchronously displayed on the dot-matrix color display screen 5, and from the perspective of the driver, the pattern corresponding to the indicator light information is just located in the black spot region 56, so that the pattern corresponding to the indicator light is obviously distinguished from the peripheral background image or background animation 53, so that the driver can distinguish the indicator light information at a glance. The area of the black spot region 56 is significantly larger than the area of the indicator light projection region, so that the black spot region 56 is more conspicuous in the background image or background animation 53, further ensuring that the driver can notice the relevant indicator light information.

In addition, the outer contour of the black spot region 56 may correspond to the outer contour of the pattern corresponding to the corresponding indicator light information (see fig. 17), for example, the outer contour of the black spot region 56 corresponding to the left turn light 49 is also the style of the left turn light 49; or the outer contour of the black spot area 56 is an ellipse or a rectangle (see fig. 16), and the shape of the outer contour of the black spot area 56 is not affected by the outer contour of the pattern corresponding to the indicator light information.

In a preferred embodiment, the first display screen 1 is a segment code screen 4, the second display screen 2 is a dot matrix color display screen 5, and the dot matrix color display screen is an LCD screen or an OLED screen. Of course, the first display screen 1 may also be a dot matrix color display screen 5, and the second display screen 2 may also be a segment code screen 4.
