Description
Technical Field
The invention relates to a vehicle-mounted central control display screen module, in particular to a vehicle-mounted front spliced display screen module.
Background
In the electric vehicle era, the acceleration performance far surpasses that of a fuel vehicle, and the spelling performance is almost meaningless, so that the electric vehicle is converted into the spelling science and technology sense from the spelling power performance, particularly in the cabin field, large screens and multiple screens are basically standard and matched with the electric vehicle, the medium-high-end fuel vehicle also has to adopt multiple screens or the large screens to compete with the electric vehicle, and the display screen for super-large driving is in love.
The current front-row screen design often adopts the scheme of three screens of instrument screen, maincenter screen and vice screen, can use a monoblock cover plate glass to encapsulate three screens together when arranging and embody the effect of integration. However, the existing scheme only solves the integrated effect after the screen is locked and the screen is not in use, once the screen of the unlocking vehicle is lightened, the three screens are respectively lightened and a large black edge is arranged between the screens, the integrated effect is suddenly eliminated, and the existing design causes relative independence between the three screens, so that the integrated use experience cannot be realized.
In the prior art, there are several methods for eliminating the black edge of the screen:
the first scheme is as follows: to the mode of a plurality of screen concatenations, set up the connector in the concatenation seam of screen, connector itself possesses luminous function, when the connector sets up between two adjacent screens, connector itself possesses the diffusion layer that is used for diffusing light, when two adjacent screens were lighted, connector itself can refract light simultaneously, through the luminous mode of screen-connector-screen, the connector can reduce the difference of screen display in luminance to this reaches the effect that reduces the influence of black border. In the first scheme, the connector does not independently emit light, but the light of the adjacent screen is refracted to achieve the effect of light emission.
Scheme II: for the way of splicing a plurality of screens, for example, in the case of splicing a plurality of LCD screens to each other, the light emitting diode LED is disposed between two or more adjacent LCD screens, the display of the LCD display screen is associated with the display of the light emitting diode LED, and the display edge of the light emitting diode LED is attached to the display edge of the LCD display screen. As an alternative to significantly increasing the cost, the light emitting diodes LED may be of a type that does not have a bezel edge (or a narrow bezel edge), in cooperation with which the edge thickness of the LCD display panel is greater than the thickness of the light emitting diode LED bezel edge. When displaying, the contents displayed by the LCD screen and the LED screen are matched, that is, the contents displayed by the LED are matched with the contents displayed by the adjacent LCD screen. In order to realize the scheme, the second scheme needs a specific signal processing module, so that the LED and the LCD screen are linked, the signal control module needs to control the display synchronization between the LCD display panel and the LED in the display screen, and a complete display picture needs to be combined, so that the tearing feeling and the incomplete feeling of the picture caused by the black edge phenomenon can be compensated. Therefore, in the second scheme, the light emitting diode LED and the LCD screen need to be linked.
The third scheme is as follows: for the splicing mode of a plurality of screens, the composite glass made of the low-refractive-index material is spliced at the black edge of each display screen, so that a trapezoidal structure is formed near the adjacent display screens and the frames thereof, or the composite glass made of the high-refractive-index material is spliced at the black edge of each display screen, so that a honeycomb structure is formed near the adjacent display screens and the frames thereof. Therefore, the composite glass of the third scheme does not independently emit light, but achieves the effect of light emission by refracting light rays of adjacent screens.
In the prior art, other light emitting components or transition screens are arranged between the central control display screens, and the black edges are relieved by jointly lighting the central control display screens and the other light emitting components. However, in any method, the method of directly using hardware to eliminate the black edge mainly has the following 2 problems:
1. the cost and expense are particularly high, a particularly expensive ultra-narrow screen is needed, and the system is not suitable for a vehicle-mounted central control screen;
2. for a common vehicle-mounted screen, the black edge is still obvious, and a good display effect cannot be achieved.

Examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
Referring to fig. 1a and 1b, the invention discloses a spliced display screen set of a front row of a vehicle, which is mounted at the front row of the vehicle, namely, a driver, a center console and a copilot position. As shown in fig. 1a and 1b, the tiled display screen set of the present invention includes a first display screen 11, a second display screen 12, and a third display screen 13, wherein the first display screen 11 is disposed at a position in front of a driver of a center console, i.e., at a position of an instrument panel; the second display screen 12 is arranged in the center of the center console, namely the traditional center console position; the third display 13 is provided at a position ahead of the passenger compartment, that is, at a position where the glove box faces the passenger compartment.
With continued reference to fig. 1a and 1b, the tiled display panel set includes a central light-emitting module 14 and a peripheral light-emitting module 15 in addition to the first display panel 11, the second display panel 12 and the third display panel 13. Wherein, central luminous module 14 sets up between first display screen 11 and second display screen 12 to and between second display screen 12 and the third display screen 13, and peripheral luminous module 15 encircles first display screen 11, second display screen 12 and third display screen 13. Specifically, the peripheral light emitting module 15 surrounds the left side and the upper and lower sides of the first display 11, the upper and lower sides of the second display 12, and the right side and the upper and lower sides of the third display 13.
Fig. 1a shows an arrangement of a first display panel 11, a second display panel 12, a third display panel 13, a central light-emitting module 14, and a peripheral light-emitting module 15 according to a first embodiment of the present invention. In the arrangement shown in fig. 1a, the length of the central light-emitting module 14 is longer than the width of the first display 11, the second display 12 and the third display 13, so the central light-emitting module 14 penetrates the width direction of the whole tiled display set. In the arrangement shown in fig. 1b, the length of the central light-emitting module 14 is the same as the width of the first display 11, the second display 12, and the third display 13, so the peripheral light-emitting module 15 completely surrounds the first display 11, the second display 12, the third display 13, and the periphery of the central light-emitting module 14.
With the splicing structure shown in fig. 1a and 1b, the spliced display screen set of the present invention can at least realize the following display modes:
1. normal driving mode:
the normal driving mode is divided into an instrument display area (first display screen 11), a navigation area (second display screen 12), and a passenger area (third display screen 13). The center of the first display screen 11 can display a special effect instrument panel, the pixels at the edge of the first display screen 11 gradually transit to black and coincide with a black edge, and meanwhile, the micro LED part of the central light-emitting module 14 displays an indicator lamp. The second display screen 12 displays a navigation map, the edge of the navigation map is gradually changed from a bright color to a dark color, and the micro LED modules of the peripheral light-emitting modules 15 around the navigation map display the vehicle-mounted control keys 141.
2. Low power consumption mode:
and entering a low power consumption mode, closing the first display screen 11, the second display screen 12 and the third display screen 13, and displaying a digital instrument and necessary indicator lamps through the MicroLED of the central light-emitting module 14.
3. A safety mode:

4. Welcome mode:
and when entering the welcome mode, brightness gradient adjustment is carried out in the area close to the black edge.
5. The screen saver mode comprises the following steps:
when entering the screen saver mode, brightness gradient adjustment is performed near the black edge area.
As an embodiment of the present invention, the central light emitting module 14 and the peripheral light emitting module 15 are micro led lattices. The micro LED is composed of red, green and blue LED lamp beads in an equidistant arrangement mode, self-illumination can be achieved, each micro LED module can define numbers through software and conduct self-networking, and the control end can conduct independent display according to the module numbers.
Referring to fig. 2a and 2b, the tiled display panel set can have different tiled stacked structures according to the display panel selection.
As shown in fig. 2a, the first Display screen 11, the second Display screen 12, and the third Display screen 13 are Liquid Crystal Displays (LCDs), the first Display screen 11, the second Display screen 12, and the third Display screen 13, the central light-emitting module 14, and the peripheral light-emitting module 15 form a 4-layer panel structure, the bottom layer of the 4-layer panel structure is a backlight 21, the upper layer thereof is an LCD and micro led Display layer 22, the upper layer thereof is a touch layer 23, and the uppermost layer thereof is a glass cover plate 24.
With continued reference to the splicing and laminating structure of fig. 2a, in the 4-layer panel structure, the back surfaces of the first display screen 11, the second display screen 12, the central light-emitting module 14 and the peripheral light-emitting module 15 have an integrated backlight 21, that is, the first display screen 11, the second display screen 12, the central light-emitting module 14 and the peripheral light-emitting module 15 share the same backlight 21 panel. Meanwhile, the display layers 22 of the first display screen 11, the second display screen 12, the central light-emitting module 14 and the peripheral light-emitting module 15 are mutually abutted and arranged on the same layer, that is, the present invention does not directly splice the existing LCD screen and the micro led light-emitting panel, but re-installs the internal structure thereof, and not only adopts the unified backlight source 21, but also installs the display layers 22 of the first display screen 11, the second display screen 12, the central light-emitting module 14 and the peripheral light-emitting module 15 on the same layer. The upper layer of the display layer 22 is a touch layer 23, and the upper layer of the touch layer 23 is a glass cover plate 24.
The prior art tiled screen uses a plurality of individual display panels, light-emitting panels, each LCD using an individual touch layer 23 and backlight 21. In contrast, in the 4-layer panel structure of the present invention, the backlight 21 is integrally designed, the touch layer 23 and the cover glass are integrally designed in a uniform size, and the glass cover 24 is also integrally designed. Compared with the prior art, the 4-layer panel structure can effectively reduce the black edges between the first display screen 11, the second display screen 12, the central light-emitting module 14 and the peripheral light-emitting module 15.
As shown in fig. 2b, the first display panel 11, the second display panel 12, and the third display panel 13 are Organic Light-Emitting Diode (OLED) displays, and since the OLEDs are self-luminous, a unified backlight 21 is not required.
Although the prior art also has various structures to reduce the black margin between the spliced screens as much as possible, the black margin is still unavoidable in practical application, and the black margin of the conventional spliced screen is still obvious, and if an ultra-narrow border screen with a very high price is adopted, on one hand, the screen with the very high price is not suitable for a vehicle-mounted screen, and on the other hand, the problem of the black margin of the spliced screen cannot be solved ideally even if the ultra-narrow border screen is adopted. Therefore, the invention adopts a matched display scheme to further achieve the effect of visual deception besides the structure of the spliced display screen group.
As described in the second embodiment of the background art, the second embodiment is also a solution for splicing the light emitting diode LED between two LCD screens. However, in the prior art, independent light-emitting panels and display light sources are respectively adopted behind the LCD screens and the light-emitting diodes LEDs, and an additional signal control module is required to synchronize the display contents of the LCD screens and the light-emitting diodes LEDs, so that the display screen has an integrated feeling, and no obvious visual tearing feeling or discomfort feeling is generated.
However, the LCD screen/LED without frame edge (or ultra-narrow frame edge) adopted in the second solution is not generally used for the display screen in the front row of the vehicle due to various reasons such as cost, size, and technical application, and on the other hand, the on-board device has higher requirements for stability and anti-interference performance, so that the LCD screen and the LED are generally rarely used to implement synchronization of the pictures, which consumes a lot of computing power, and for the on-board processor, more computing power should be used for vehicle safety control, rather than real-time picture synchronization.
As a first embodiment of the present invention, a first display screen 11, which displays on-vehicle instrument information, is located in front of the driver; the second display screen 12 is positioned in the central console area and displays a vehicle-mounted control interface; a third display screen 13, positioned in front of the copilot, displays auxiliary and entertainment information; the central light-emitting module 14 is disposed between the first display screen 11 and the second display screen 12, and between the second display screen 12 and the third display screen 13, and displays the vehicle-mounted control key 141. The edge display brightness and color of the first display screen 11 and the second display screen 12 are matched with the brightness and color of the central light-emitting module 14 sandwiched between the first display screen 11 and the second display screen 12, so that the first display screen 11, the central light-emitting module 14 and the second display screen 12 form a uniform visual effect. Similarly, the second display screen 12, the central light-emitting module 14, and the third display screen 13 also form a unified visual effect.
As shown in fig. 3, the above display is characterized in that the central light emitting module 14 (micro led) of the present invention is also loaded with the touch layer 23, so that the central light emitting module 14 located between the first display screen 11 and the second display screen 12 (and the second display screen 12 and the third display screen 13) has functionality as the first display screen 11 and the second display screen 12, rather than a simple display effect. The vehicle-mounted control key 141 is arranged on the central light-emitting module 14, and through the arrangement of the vehicle-mounted control key 141, a visual focus point of a user in use can pay more attention to the vehicle-mounted control key 141 displayed by the central light-emitting module 14, so that black edges at junctions of the central light-emitting module 14 and the first display screen 11 and the second display screen 12 (and the second display screen 12 and the third display screen 13) can be faded. Meanwhile, the edge display brightness and color of the first display screen 11 and the second display screen 12 (and the second display screen 12 and the third display screen 13) are matched with other display areas (display areas except the vehicle-mounted control key 141) of the central light-emitting module 14, so that a better visual cheating effect is formed among the first display screen 11, the second display screen 12 and the third display screen 13.
The central light module 14 uses a micro led dot matrix different from the conventional screen, and in order to reduce unnecessary cost, the central light module 14 has a strip structure, generally has a relatively small area, and is used to display the vehicle control key 141 in the present invention. When the vehicle-mounted control key 141 is turned on, the bright area of the key part can achieve certain visual deception effect on the dark area of the rest part, the first display screen 11 and the second display screen 12 (the second display screen 12 and the third display screen 13) and surrounding micro LED modules are turned on, simple pictures such as the vehicle-mounted control key 141 are displayed on the micro LED modules in cooperation with UI design, the visual effect of black edge disappearance can be achieved, and user experience of a vehicle-mounted full-screen is achieved.
In the prior art, the black border is usually eliminated simply by a "display" mode, that is, the central light-emitting module 14 is simply matched with the first display screen 11 and the second display screen 12 on the display, and the three display the same or consecutive pictures. However, the ideal effect of visual deception still cannot be achieved, and after all, the black edge of the spliced part is still easy to be found in the same image. On the other hand, if different images are intentionally displayed on the first display screen 11, the central light-emitting module 14, and the second display screen 12 in sequence, the black edges at the joints are easily revealed due to over-deliberate effects.
In contrast, the advantage of the foregoing method of the present invention is that the present invention not only adopts the visual deception effect in the aspect of "displaying", that is, the matching of the brightness and the color of the first display screen 11, the central light-emitting module 14 and the second display screen 12, but also makes the visual transition more natural by the division of the functional areas by arranging the vehicle-mounted control key 141 on the central light-emitting module 14, and the arrangement of the vehicle-mounted control key 141 can disperse the attention of the user, so that the visual deception effect is significantly improved. In order to achieve the above technical effects, the present invention particularly provides the splicing and stacking structure shown in fig. 2a and 2b, so that on one hand, the first display screen 11, the central light-emitting module 14, and the second display screen 12 have a more compact structure and a smaller physical black edge, and on the other hand, the central light-emitting module 14 needs to be additionally provided with the touch layer 23, so that the central light-emitting module can have a function of displaying the vehicle-mounted control key 141 and responding to the user operation.
On the other hand, the width of the central light module 14 of the present invention is selected specifically, and the width thereof corresponds to the width of the frame of the general in-vehicle control key 141. Generally, on the vehicle-mounted UI display, each vehicle-mounted control key has a 'frame' effect in order to highlight the display and achieve the effect that a user can notice at a glance, but according to the technical scheme, the vehicle-mounted control keys 141 with specific widths are selected, the specific splicing laminated structure of the first display screen 11, the central light-emitting module 14 and the second display screen 12 is matched, and then the combined display content of the first display screen 11, the central light-emitting module 14 and the second display screen 12 is integrated, so that the original 'black edge' serves as the 'frame' effect of the vehicle-mounted control keys 141 through the combined display effect of the three factors, and the ideal visual deception effect of hiding the black edge is achieved. Here, the width selection of the central light-emitting module 14 realizes the "positioning" of the specific position of the black border, i.e. the black border is located at the position of the "frame" of the vehicle-mounted control key 141; the specific splicing laminated structure of the first display screen 11, the central light-emitting module 14 and the second display screen 12 enables the width of the black edge to be reduced as much as possible, otherwise even if the width of the black edge is too large in combination with other two factors, the effect of visual deception is greatly reduced; the combined display contents of the first display screen 11, the central light-emitting module 14 and the second display screen 12 play a role of direct visual deception, but such visual deception cannot be really achieved without cooperation of other two factors.
Therefore, the first embodiment of the invention realizes a better black edge hiding effect through a hardware structure and screen display.
As a second embodiment of the present invention, the peripheral light-emitting module 15 displays additional information, and the brightness and color of the additional information are matched with the brightness and color of the edge display of the first display screen 11 and the second display screen 12, so that the peripheral light-emitting module 15, the first display screen 11 and the second display screen 12 form a unified visual effect. Similarly, the peripheral light-emitting module 15, the second display screen 12 and the third display screen 13 also form a unified visual effect.
In the present invention, the additional information may also be the in-vehicle control key 141 or other information that can respond to the touch control. The peripheral light-emitting module 15 and the central light-emitting module 14 are similar, on one hand, the structure is more compact and the physical black edge is smaller through a splicing laminated structure, and on the other hand, the touch layer 23 is additionally arranged, so that the vehicle-mounted control key 141 can be displayed and the function of responding to the operation of a user can be realized. Through the mode, the peripheral light-emitting module 15 has the visual deception effect in the aspect of display, and the attention of a user is dispersed by matching with the arrangement of the vehicle-mounted control key 141, so that the visual deception effect is obviously improved.
In this embodiment, the console further includes an exterior trim panel that includes a light absorbing, reflecting material. The outer decorative plate covers the first display screen 11, the second display screen 12, the third display screen 13, the central light-emitting module 14 and the peripheral light-emitting module 15. In order to cooperate with the exterior panel, the width of the peripheral light-emitting module 15 is much smaller than the width of the first display screen 11, the second display screen 12 and the third display screen 13. In this way, the peripheral light emitting module 15 forms a stripe structure on the periphery of the first display 11, the second display 12, and the third display 13.
Meanwhile, the brightness of the peripheral light-emitting module 15 is greater than the brightness of the width of the first display screen 11, the second display screen 12 and the third display screen 13, so that when the first display screen 11, the second display screen 12, the third display screen 13, the central light-emitting module 14 and the peripheral light-emitting module 15 are simultaneously lighted, the peripheral light-emitting module 15 with a strip structure can realize atmosphere drawing of the whole screen, gradual change of color, pictures and characters can be displayed, and the peripheral light-emitting module 15 is enabled to display higher brightness through the periphery and lower internal display brightness. On the basis of the first embodiment of the present invention, the second embodiment of the present invention is combined with the light reflection of the exterior plate material, so that the first display screen 11, the central light emitting module 14, and the second display screen 12 can form a uniform visual effect.
Therefore, the second embodiment of the present invention realizes a better black edge hiding effect by matching the display brightness and the reflective matching of the peripheral exterior trim panel, and the first and second embodiments of the present invention can be used in combination to enhance the visual effect.
Referring to fig. 4, as an embodiment of the present invention, the central light-emitting module 14 and the peripheral light-emitting module 15 respectively have a plurality of interfaces, and each micro led dot matrix (the central light-emitting module 14 or the peripheral light-emitting module 15) includes an integrated circuit bus interface (I2C), a Low Voltage Differential Signaling (LVDS) interface, a default pull-down logic gate circuit (TTL) input interface, a weak pull-down logic gate circuit output interface, and the like.
As shown in fig. 4, the integrated circuit bus interfaces (I2C) of the central light-emitting module 14 and the peripheral light-emitting module 15 are respectively connected in parallel with the on-board host 31, the Low Voltage Differential Signaling (LVDS) interfaces of the central light-emitting module 14 and the peripheral light-emitting module 15 are connected in parallel and to the output terminal of the on-board host 31, the TTL input interfaces and the TTL output interfaces of the central light-emitting module 14 and the peripheral light-emitting module 15 are connected to the on-board host 31 by daisy chain, that is, the TTL output interface of the first module (the central light-emitting module 14) is connected to the TTL input interface of the second module (the peripheral light-emitting module 15), the TTL output interface of the second module (the peripheral light-emitting module 15) is connected to the TTL input interface of the third module, and so on, the TTL output interface of the last module and the TTL input interface of the first module are both connected to the on-board host 31 as a ring. It will be understood by those skilled in the art that the first module is selected as the central light-emitting module 14 and the second module is selected as the peripheral light-emitting module 15 in fig. 4, which are only illustrative and not limiting. The system of the present invention may include a plurality of central light modules 14, peripheral light modules 15, as shown in fig. 1a and 1b, all of which may be daisy-chained in the configuration shown in fig. 4.
In one embodiment of the present invention, when the in-vehicle host 31 is powered on, the logic gate circuit (TTL) output interfaces of the central light-emitting module 14 and the peripheral light-emitting module 15 both output a low level. After the vehicle-mounted host 31 is started, high level is output to the central light-emitting module 14 and/or the peripheral light-emitting module 15 through the I/O port, and networking is performed by using an integrated circuit bus interface and a logic gate circuit output interface of the central light-emitting module 14 and/or the peripheral light-emitting module 15, so that the displays of the central light-emitting module 14 and the peripheral light-emitting module 15 can be matched with each other.
Specifically, as shown in fig. 4, after the input interface of the central light-emitting module 14 receives the high level sent by the host, the I2C interface sends its own I2C address and module number information (each module number is unique) to the on-board host 31, after the on-board host 31 finishes information collection of the central light-emitting module 14, its own I/O output port is set low, and at the same time, a command is sent to the central light-emitting module 14 to set it to be the high TTL output interface; after the TTL input interface of the peripheral light-emitting module 15 receives the high level, it completes the information transmission and operation as the central light-emitting module 14, until all modules complete configuration and networking is completed. The legend information of networking completion can be displayed on the central screen, and a user can select different central light-emitting modules 14 and/or peripheral light-emitting modules 15 to independently display or combine to display according to own requirements, and meanwhile, an intelligent display mode is supported.
In summary, controlling the black edge of the tiled screen is a problem that is difficult to process in the prior art, and the prior art processes only through a hardware structure and also processes only through software display. The invention combines two aspects of hardware and software, on one hand, the black edge is weakened structurally through a splicing laminated structure among the first display screen 11, the second display screen 12, the third display screen 13, the central light-emitting module 14 and the peripheral light-emitting module 15, and on the other hand, the black edge is further eliminated through visual deception of the display layer by matching with the structural layer.
