The invention provides a display method of automobile instrument information, please refer to fig. 1, the method includes the steps:
s100, a segment code screen 1, a dot matrix color display screen 2 and a light reflecting and transmitting plate 3 are respectively provided, wherein a plurality of information controllable display area groups 13 (shown in fig. 5, for example) are arranged in the segment code screen 1, and a first side surface of the light reflecting and transmitting plate 3 has a light reflecting property and a second side surface thereof has a light transmitting property.
Wherein each information controllable display area group 13 can be individually controlled to display. When a certain information controllable display area group 13 is displayed, a display pattern is presented on the display surface of the segment code screen 1. The dot matrix color display screen 2 can display any image as required.
Further, the dot matrix color display screen 2 may be a TFT display screen or an OLED display screen.
S200, for example according to the example of fig. 3, will anti-light-passing board 3 slope sets up, makes its first side towards the front upper side, and the second side is towards the back below, will section sign indicating number screen 1 set up in anti-light-passing board 3 'S upside, just section sign indicating number screen 1' S display surface is towards first side will dot matrix color display screen 2 set up in anti-light-passing board 3 'S rear side, just dot matrix color display screen 2' S display surface is towards the second side makes segment sign indicating number screen 1 'S display surface warp the mirror image plane that anti-light-passing board 3' S first side formed with dot matrix color display screen 2 'S display surface approximately overlaps, just mirror image plane is located the place ahead of dot matrix color display screen 2' S display surface.
Referring to fig. 4, when the segment code screen 1 displays, the segment code image 11 is displayed on the display surface of the segment code screen 1, the segment code image 11 forms a mirror image 12 with respect to the first side surface (the mirror image 12 is located on the mirror image surface), when the dot matrix color display screen 2 displays, the color image 21 is displayed on the display surface of the dot matrix color display screen 2, so that the mirror image 12 is located in front of the color image 21, and the mirror image 12 is substantially parallel to the color image 21, and at the viewing angle of the driver, the driver can see the mirror image 12 and the color image 21 simultaneously through the translucent plate 3, and there is a distance between the mirror image 12 and the color image 21 in the front-rear direction, so that the driver sees the stereo combined image 22 with a far-near relationship.
S300, providing a control unit, and electrically connecting the control unit with the segment code screen 1 and the dot matrix type color display screen 2 respectively; the control unit stores a plurality of information background patterns and a plurality of background images for the dot matrix color display screen 2 to display.
The control unit can control each information controllable display area group 13 in the segment code screen 1 to display or stop displaying, so that the purpose of displaying the segment code image 11 through the segment code screen 1 is achieved; the control unit can display the information background pattern and the background image stored in the control unit through the dot matrix type color display screen 2, thereby realizing the purpose of displaying the color image 21.
S400, the control unit is used for controlling one or more information controllable display area groups 13 in the segment code screen 1 to display, and controlling the dot matrix type color display screen 2 to display preset information background patterns and background images, wherein the information background patterns currently displayed on the dot matrix type color display screen 2 and the display patterns (located on the segment code images 11) of the information controllable display area groups 13 currently displayed on the segment code screen 1 have preset corresponding relations, and therefore the mirror image patterns of the display patterns in the mirror image plane are located in front of the corresponding information background patterns.
In general, the control unit controls the dot matrix color display screen 2 to display a background image, at this time, the whole color image 21 is the background image, when the control unit controls the information controllable display area group 13 on the segment code screen 1 to display, the control unit also synchronously controls the dot matrix color display screen 2 to display an information background pattern, when the information background pattern is displayed, the information background pattern is displayed in an overlapping manner on the background image (the information background pattern covers a part of the background image), so that the color image 21 simultaneously displays the background image and the information background pattern, because the mirror image 12 and the color image 21 are overlapped in the front-back direction, the mirror image pattern on the mirror image 12 (the pattern formed on the mirror image 12 when the information controllable display area group 13 displays) is just in front of the information background pattern, so that the mirror image pattern and the information background pattern are overlapped under the visual angle of the driver, that is, the mirror image pattern is displayed on the information background pattern, and further, the mirror image pattern and the information background pattern have a significant color difference, so that the driver can easily recognize the mirror image pattern on the combined image 22, and the interference of the background image on the mirror image pattern is avoided.
Referring to fig. 6-8, for example, taking the display of the left turn lamp image pattern 141 as an example, the driver turns the steering lever to turn on the left turn lamp, the control unit receives the left turn signal, and the control unit controls the left turn lamp controllable display area group 14 on the segment code screen 1 to display (an information controllable display area group 13), so that the left turn lamp display pattern (a display pattern) is displayed on the segment code image 11, and the left turn lamp image pattern 141 (a mirror pattern) is displayed on the mirror image 12. In addition, the control unit simultaneously controls the dot matrix color display panel 2 to display the left-turn lamp background pattern 142 (an information background pattern), and the left-turn lamp background pattern 142 is superimposed on the background image, the left-turn lamp background pattern 142 blocks part of the background image at the superimposed position, that is, at the position of the left-turn lamp background pattern 142 on the color image 21, the driver only sees the left-turn lamp background pattern 142 without seeing the background image, the background image is only displayed at the part outside the left-turn lamp background pattern 142, the left-turn lamp image pattern 141 is located in front of the left-turn lamp background pattern 142, and at the viewing angle of the driver, the left-turn lamp image pattern 141 is completely located in the left-turn lamp background pattern 142, and since there is a significant color difference between the color of the left-turn lamp image pattern 141 and the color of the left-turn lamp background pattern 142, the driver can easily see the left-turn lamp image pattern 141 from the combined image 22, thereby obtaining the vehicle turn-on left turn light information.
The mirror image pattern and the information background pattern can be displayed in a single color, and the corresponding mirror image pattern and the corresponding information background pattern are different in color, so that a driver can distinguish the mirror image pattern easily when the corresponding mirror image pattern and the corresponding information background pattern are displayed, and the driver can obtain corresponding instrument information conveniently.
This application can make the instrument information on the motormeter mostly show through section code screen 1 through setting up the controllable display area group of a plurality of information 13 on section code screen 1. Because the display content corresponding to the meter information is relatively fixed, the meter information is particularly suitable for being displayed by the segment code screen 1. On the combined image 22, since the mirror image 12 is spaced from the color image 21 in the front-rear direction, the combined image 22 having a difference in distance is visible to the driver, so that the combined image 22 has a stereoscopic effect. In addition, when each mirror image pattern is displayed, a corresponding information background pattern can be synchronously displayed, so that the driver can clearly see the mirror image pattern, and the driver can conveniently obtain corresponding instrument information.
Preferably, the number of the information background patterns is equal to and corresponds to the number of the information controllable display area groups 13, so as to ensure that the control unit can control the dot matrix color display screen 2 to display the corresponding information background patterns when the control unit controls any one of the information controllable display area groups 13 to display.
Preferably, in step S400, the outer contour area of the mirror image pattern is smaller than the outer contour area of the corresponding information background pattern, and the information background pattern is a black pattern. Taking the left turn light as an example, the outer contour area of the left turn light image pattern 141 is smaller than the outer contour area of the left turn light background pattern 142, so that the left turn light image pattern 141 is ensured to be located in the left turn light background pattern 142 under the view angle of the driver, and the left turn light background pattern 142 is a black pattern, so that the left turn light image pattern 141 is equivalent to be displayed under the black background, and the left turn light image pattern 141 is more visible; in addition, on the color image 21, the black left-turn light background pattern 142 is superimposed and displayed on the background image, so that the left-turn light background pattern 142 is more conspicuous on the color image 21, and can also play a role in reminding the driver of paying attention to the relevant meter information.
Preferably, the outer contour area of the information background pattern is 1.3-1.5 times of the outer contour area of the corresponding mirror image pattern, and the outer contour of the information background pattern is rectangular, oval or circular.
Preferably, referring to fig. 5, in step S100, the plurality of information controllable display area groups 13 include a first digital main controllable display area group 15, a second digital main controllable display area group 16, a first digital auxiliary controllable display area group 17, and a second digital auxiliary controllable display area group 18, where the first digital main controllable display area group 15 and the first digital auxiliary controllable display area group 17 are located on the left side of the segment code screen 1, the second digital main controllable display area group 16 and the second digital auxiliary controllable display area group 18 are located on the right side of the segment code screen 1, and two auxiliary controllable display area groups are located at corner positions of the segment code screen 1, and an outer contour area of the main controllable display area group is larger than an outer contour area of the auxiliary controllable display area group.
Referring to fig. 12 to 14, in step S400, the background image includes a navigation screen 23, when the dot matrix color display screen 2 displays the navigation screen 23, the first digital main controllable display area group 15 and the second digital main controllable display area group 16 stop displaying, and the first digital auxiliary controllable display area group 17 and the second digital auxiliary controllable display area group 18 start displaying (a first digital auxiliary mirror image pattern 171 and a second digital auxiliary mirror image pattern 181 are displayed on a mirror 12), the dot matrix color display screen 2 synchronously stops displaying information background patterns corresponding to the first digital main controllable display area group 15 and the second digital main controllable display area group 16, and synchronously starts displaying information background patterns corresponding to the first digital auxiliary controllable display area group 17 and the second digital auxiliary controllable display area group 18 (a first digital auxiliary background pattern 172 is displayed on a color image 21) And a second digital auxiliary background pattern 182).
The automobile instrument related by the invention has a navigation function. During navigation, the control unit controls the dot matrix color display 2 to display a corresponding navigation screen 23 (see fig. 13), so that the navigation screen 23 is not shielded by the mirror image 12 as much as possible for a driver to obtain corresponding navigation information. The mirror image 12 is composed of individual mirror image patterns, as mentioned above, each mirror image pattern usually corresponds to a meter information, and under normal conditions of the vehicle, most of the information controllable display area groups 13 are in a stop display state, but the first digital main controllable display area group 15 and the second digital main controllable display area group 16 need to be in a display state for a long time (see fig. 9, the first digital main mirror image pattern 151 and the second digital main mirror image pattern 161 are displayed on the mirror image 12 for a long time), so as to facilitate the driver to obtain the first digital information and the second digital information, and when the first digital main controllable display area group 15 is displayed, the control unit further needs to control the dot matrix type color display 2 to display the information background patterns corresponding to the first digital main controllable display area group 15 and the second digital main controllable display area group 16 (see fig. 10, the first digital main background pattern 152 and the second digital main background pattern 162, respectively), due to the large outer contour area and the limited position of the first digital main controllable display area group 15 and the second digital main controllable display area group 16, the first digital main background pattern 152 and the second digital main background pattern 162 overlap and cover most of the area of the navigation picture 23 (referring to fig. 11, the background image in fig. 11 may be replaced by the navigation picture), which affects the driver to obtain the navigation information from the navigation picture 23.

Because the third information dial plate patterns are multiple, each third information dial plate pattern has an independent style (namely, the style and the style between the third information dial plate patterns are different), and similarly, each fourth information dial plate pattern has an independent style, the control unit can control the dot-matrix color display screen 2 to switch and display different third information dial plate patterns and fourth information dial plate patterns, and the purpose of changing the style and the style of the engine speed dial plate patterns and the vehicle speed dial plate patterns is achieved. Specifically, the driver can select the third information dial pattern and the fourth information dial pattern that he wants according to personal taste.
Furthermore, the number of the third information dial plate patterns is equal to that of the fourth information dial plate patterns, the third information dial plate patterns and the fourth information dial plate patterns which correspond to each other are in one-to-one correspondence, the third information dial plate patterns and the fourth information dial plate patterns which correspond to each other have approximately the same style, and when the control unit controls the dot matrix type color display screen 2 to display one third information dial plate pattern, the control unit can also synchronously control and display the fourth information dial plate pattern corresponding to the third information dial plate pattern, so that the style and style of the engine speed dial plate pattern and the style and style of the vehicle speed dial plate pattern are basically consistent.

s500, detecting state information when one or more information controllable display area groups 13 in the segment code screen 1 are displayed by using the control unit.
When the control unit controls any one of the information controllable display area groups 13, the control unit can also detect the state information of the information controllable display area group 13.
S600, the control unit judges whether the corresponding information controllable display area group 13 is actually displayed or not according to the state information; if the information controllable display area group 13 is not actually displayed, the control unit controls the dot-matrix color display screen 2 to display an auxiliary display pattern, where the auxiliary display pattern and the information controllable display area group 13 have a preset corresponding relationship to replace the information controllable display area group 13 to display.
The control unit judges whether the corresponding information controllable display area group 13 is actually displayed or not through the state information, if the information controllable display area group 13 is actually displayed, the control unit keeps the information controllable display area group 13 in a display state; if the control unit determines that the information controllable display area group 13 is not actually displayed, the control unit controls the display of the auxiliary display pattern corresponding to the information controllable display area group 13, so as to ensure that the relevant instrument information can be normally displayed on the combined image 22, and the mirror image pattern formed by the corresponding information controllable display area group 13 (assuming that the information controllable display area group 13 is displayed and the corresponding auxiliary display pattern is also displayed) is consistent with the pattern and position of the corresponding auxiliary display pattern under the view angle of the driver.
Referring to fig. 17, taking the left turn as an example, the driver toggles the turn lever, turns on the left turn light, the control unit receives the left turn signal, the control unit controls the left turn light controllable display area group 14 on the segment code screen 1 to display, the dot matrix color display screen 2 displays the left turn light background pattern 142, the control unit synchronously obtains the state information of the left turn light controllable display area group 14, and judges whether the left turn light controllable display area group 14 actually displays according to the state information, if the left turn light controllable display area group 14 actually displays, the control unit stops further control according to the toggling of the turn lever; if the left turn light controllable display area group 14 fails to actually display, the control unit controls the dot matrix color display screen 2 to display the left turn light auxiliary display pattern 143, so that the driver can normally acquire the left turn light information on the combined image 22. When the left turn lamp auxiliary display pattern 143 is displayed, the left turn lamp auxiliary display pattern 143 is located within the left turn lamp background pattern 142, so that the driver can acquire the left turn lamp information from the same position of the combined image 22 regardless of whether the left turn lamp image pattern 141 or the left turn lamp auxiliary display pattern 143 is displayed.
The auxiliary display pattern is arranged, so that when part or all of the information controllable display area group 13 in the segment code screen 1 is normally displayed, the control unit displays the corresponding auxiliary display pattern through the dot matrix type color display screen 2 to replace the corresponding mirror image pattern, thereby ensuring that the automobile instrument related to the invention can not lose the display pattern, and ensuring that a driver can effectively acquire the corresponding instrument information from the combined image 22.
Preferably, referring to fig. 18, in step S600, when the auxiliary display pattern is displayed on the dot matrix color display 2, the control unit controls the dot matrix color display 2 to stop displaying the background pattern corresponding to the auxiliary display pattern.
In step S400, the control unit already controls the background pattern to display, but in step S500, the control unit determines that the information controllable display area group 13 in the segment code screen 1 is not actually displayed according to the state information, at this time, the control unit controls the dot matrix color display screen 2 to display the corresponding auxiliary display pattern, and in step S600, the control unit controls the background pattern to stop displaying. In the process from step S400 to step S600, the background pattern is displayed first and then stopped, and in the actual process, the process is short, and the driver hardly feels the display of the background pattern.
When the auxiliary display pattern is displayed, the corresponding background pattern is not displayed, and because the auxiliary display pattern is directly displayed by the dot-matrix color display screen 2 and the auxiliary display pattern is overlaid on the background image, the problem of interference caused by the overlapping of the background image and the auxiliary display pattern is avoided, so that the background pattern is not displayed at the moment, and the attractiveness of the whole combined image 22 is enhanced.
When the control unit controls the left-turn light auxiliary display pattern 143 to display, the control unit synchronously controls the left-turn light background pattern 142 to stop displaying.
Preferably, in step S100, the plurality of information controllable display area groups 13 include an oil amount controllable display area group, a water temperature controllable display area group, a front fog lamp controllable display area group, an illumination lamp controllable display area group, a high beam lamp controllable display area group, a tire pressure low warning lamp controllable display area group, a left turn lamp controllable display area group 14, a right turn lamp controllable display area group, a seat belt warning lamp controllable display area group, an engine fault lamp controllable display area group, and/or a cruise control indicator lamp controllable display area group.
