In descriptions for the present disclosure, “multiple” or “plurality of” may indicate at least two, such as two, three, or the like, unless otherwise specific limitations are made. In addition, terms “includes”, “has”, and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, a method, a system, a product or an apparatus including a series of operations or units is not limited to the listed operations or units, but may further include operations or units that are not listed, or other operations or units that are inherent to the process, the method, the product, or the apparatus.

A display controlling method is provided in the present disclosure. As shown inFIG.1,FIG.2andFIG.3.FIG.1is a flow chart of a display controlling method according to an embodiment of the present disclosure;FIG.2is a schematic front view of an in-vehicle display device according to a first embodiment of the present disclosure; andFIG.3is a schematic top view of the in-vehicle display device according to an embodiment of the present disclosure. The display controlling method is applied to an in-vehicle device20.

As shown inFIG.2, the in-vehicle display device20may include at least two display modules21, and the at least two display modules21may be arranged in sequence along a first direction D1.

In some embodiments, the in-vehicle display device20may be an in-vehicle central control displayer configured to display vehicle status information such as a vehicle speed, an opening-closing state of a vehicle door, and an oil amount, or may be a displayer in the vehicle configured for a user other than a driver to watch a video, or may be a display device in the vehicle having other functions, which is not limited herein.

The number of the at least two display modules21may be any one of two, or three as shown inFIG.3, ten, or other numbers, which may be determined based on an actual need and is not limited herein. When specifically arranging the at least two display modules21, a combining display module may be obtained through splicing adjacent display modules. The combining display module may perform a screen display based on all display modules. In some embodiments, the adjacent display modules may be arranged with a preset separating distance from each other. A specific arrangement may be made based on the actual need, and is not limited herein. The at least two display modules21may include at least one user front-view display module211and at least one user side-view display module212.

As shown inFIG.1, the display controlling method may include operations S11-S13.

In an operation S11, the method may include controlling each user front-view display module to display with a first brightness.

The user front-view display module may be one of the at least two display modules21.

As shown inFIG.2andFIG.3, the at least two display modules21may include the user front-view display module211and user side-view display modules212.

In the at least two display modules21, at least one display module facing towards the user may be each regarded as the user front-view display module211, and all display module other than the user front-view module(s)211may be regarded as the user side-view display module212. That is, the display module which cannot be directly viewed by the user in the at least two display modules21may be regarded as the user side-view display module212.

The brightness of the front-view display module211may be adjusted to the first brightness for displaying. In practice, the first brightness may be a preset proportion of a maximum brightness of the display modules in the at least two display modules21. For example, the first brightness may be 30%, 50%, or 70% of the maximum brightness.

In an operation S12, the method may include determining a second brightness corresponding to each user side-view display module based on a viewing angle corresponding to each user side-view display module.

In some embodiments, the second brightness may be greater than the first brightness. The user side-view display module212may be the display module other than the user front-view display module211. A distance between a user position and one of the at least one user front-view display module in a normal direction of the one of the at least one user front-view display module is a preset distance, and the viewing angle is formed by a second direction and a normal direction of a corresponding display module, the second direction being from a point on the corresponding display module toward the user position.

As shown inFIG.3, α may be the viewing angle corresponding to the user side-view display module212. That is, α may be the angle between a normal direction D3of the user side-view display module212and the second direction D2of the user side-view display module212.

TakingFIG.3as an example, a first user side-view display module212is arranged on a left side of the user front-view display module211, and a second user side-view display module212is arranged on a right side of the user front-view display module211. When a viewing angle corresponding to the first user side-view display module212is a first angle, a viewing angle corresponding to the second user side-view display module212is a second angle. The first angle has an opposite positive-negative sign relative to the second angle. In this way, the second brightness corresponding to each user side-view display module212may be determined based on an absolute value of the viewing angle corresponding to each user side-view display module212.

In an operation S13, the method may include controlling each user side-view display module to display with a corresponding second brightness.

After determining the second brightness corresponding to each user side-view display module212, a brightness of each user side-view display module212may be adjusted to the corresponding second brightness for displaying. Each second brightness may be greater than the first brightness. The second brightness corresponding to the user side-view display modules212at different positions may be different.

It should be noted that the above operations S11-S13are simply an example. In practice, an operation sequence may be adaptively adjusted in combination with a logical relationship between the operations. For example, the operation sequence may be S12-S13-S11or S12-S11-S13, which is not limited herein.

Specifically, the at least one user front-view module display module211may be at least two display modules arranged adjacent to each other. The at least two display modules21may be at least two display modules whose corresponding normal directions are parallel to each other.

Different from the prior art, according to the technical solution of the present disclosure, based on determining the user front-view module display module, the viewing angle corresponding to each user side-view display module may be determined based on a relationship between each user side-view display module and the user front-view display module and a relationship between each user side-view display module and the user position. When the at least two display modules are controlled or operated to display, the second brightness corresponding to each user side-view display module may be determined based on each viewing angle. All the second brightness may be greater than the first brightness of the user front-view display module. The user front-view display module may be controlled to display with the first brightness, and the user side-view display module may be controlled to display with the corresponding second brightness. That is, although a distance between the user side-view display module and the user position is greater than a distance between the user front-view display module and the user position, the user side-view display module may be controlled to display with the second brightness greater than the first brightness of the user front-view display module. In this way, a difference between a brightness of the user front-view display module and a brightness of the user side-view display module perceived by the user may be reduced or eliminated, such that a display brightness consistency of the in-vehicle display device using a flat screen may be improved, and a display effect of the in-vehicle display device may be improved with a low cost.

In an embodiment, the operation S12may specifically include acquiring the viewing angle corresponding to each user side-view display module.

Determining a visual brightness corresponding to each user side-view display module based on a corresponding viewing angle and a relationship curve between the visual brightness and the viewing angle, and taking the visual brightness as the second brightness corresponding to each user side-view display modules. The relationship curve between the visual brightness and the viewing angle is determined based on a haze degree of a diffuser plate of the corresponding display module.

Specifically, as shown inFIG.4,FIG.4is a curve diagram showing a relationship between a brightness proportion perceived by a user and a viewing angle according to an embodiment of the present disclosure. A curve B may be a relationship curve corresponding to the user side-view display module212, and a curve A may be a relationship curve corresponding to the user front-view display module211.

When the maximum brightness of the user front-view display module211is the same with the maximum brightness of the user side-view display module212, the brightness proportion perceived by the user described above may indicate the visual brightness. Specifically, the brightness proportion perceived by the user multiplied by the maximum brightness of the display modules may be the visual brightness perceived by the user in a corresponding viewing angle. The relationship curve between the visual brightness and the viewing angle as mentioned above may be the relationship between the brightness proportion and the viewing angle as shown inFIG.4.

In the curve A, when the viewing angle is 0°, the brightness proportion perceived by the user may be 33%. It can be seen that the first brightness of the user front-view display module211may be 33% of the maximum brightness thereof.

In the curve B, when the viewing angle is 0°, the brightness proportion perceived by the user may be 100%. It can be seen that the second brightness of a user side-view display module212may be 100% of the maximum brightness thereof. When the viewing angle is 35° or −35°, the brightness of the user side-view display module212perceived by the user is 33% of the maximum brightness thereof.

In conclusion, based on relationship curves between the brightness proportion and the viewing angle shown inFIG.4, when at the user position, the viewing angle corresponding to the user side-view display module212is 35° or −35°, while the viewing angle corresponding to the user front-view display module211is 0°, the second brightness of the user side-view display module212may be determined as 33% of the maximum brightness thereof, and the first brightness of the user front-view display module211may be determined as 33% of the maximum brightness thereof. In this way, the brightness of the user side-view display module212perceived by the user at the user position is the same with the brightness of the user front-view display module211perceived by the user at the user position, such that the display effect of the in-vehicle display device may be improved.

FIG.5is a curve diagram showing the relationship between the brightness proportion perceived by the user and the viewing angle according to another embodiment of the present disclosure. In practice, as shown inFIG.5, a curve C and a curve D are two different relationship curves between the brightness proportion perceived by the user and the viewing angle in the same display module under a case where haze degrees of a diffuser plate are different. It can be seen from theFIG.5that for the same display module, even if the brightness proportions perceived by the user are the same when the viewing angle is 0°, relationship curves (such as the curve C and the curve D) between the brightness proportion perceived by the user and the viewing angle may be different in response to the haze degrees of the diffuser plate being different.

Therefore, in practice, a detailed process of determining the curve A and the curve B may be as follows.

The brightness proportion perceived by the user when the viewing angle corresponding to the user front-view display module211is 0° may be determined, and the curve A may be determined based on a haze degree corresponding to the user front-view display module211and the brightness proportion perceived by the user when the viewing angle corresponding to the user front-view display module211is 0°.

The brightness proportion perceived by the user at the viewing angle corresponding to the user front-view display module211may be set to be the brightness proportion perceived by the user at the viewing angle corresponding to the user side-view display module212. The curve B may be determined based on a haze degree corresponding to the user side-view display module212and the brightness proportion perceived by the user at the viewing angle corresponding to the user side-view display module212. The brightness proportion perceived by the user when the viewing angle corresponding to the user side-view display module212is 0° may be determined based on the curve B.

The curve A and the curve B may be determined as described above, such that the relationship curve between the brightness proportion perceived by the user and the viewing angle corresponding to the user front-view display module211, and the relationship curve between the brightness proportion perceived by the user and the viewing angle corresponding to the user side-view display module212may be determined. In this way, the first brightness of the user front-view display module211may be determined based on the brightness proportion perceived by the user corresponding to the curve A when the viewing angle is 0° and the maximum brightness corresponding to the display modules. The second brightness of the user side-view display module212may be determined based on the maximum brightness corresponding to the display modules and the brightness proportion perceived by the user corresponding to the curve B at a corresponding viewing angle when the viewing angle corresponding to the user front-view display module211is 0°. In this way, the first brightness and the second brightness are obtained to be displayed with.

Based on the above manner, the curve B corresponding to each user side-view display module212may be constructed based on the curve A corresponding to the user front-view display module211, and the second brightness corresponding to each user side-view display module212may be determined for displaying.

In an embodiment, the operation S12may specifically include determining the second brightness corresponding to each user side-view display module based on the viewing angle corresponding to each user side-view display module and a principle that the greater the absolute value of the viewing angle, the greater a corresponding second brightness.

Specifically, it can be seen from the curves shown inFIG.4that, for the same display module, when the brightness remains unchanged, the greater the absolute value of the viewing angle, the less the brightness displayed by the display module which is perceived by the user. Therefore, the second brightness corresponding to each user side-view display module212may be determined based on the principle that the greater the absolute value of the viewing angle, the greater the corresponding second brightness, such that the brightness of the user side-view display module212of which viewing angle is not 0° may be improved. In this way, the brightness of the user side-view display module212of which viewing angle is not 0° perceived by the user may be the same with the brightness of the user front-view display module211of which the viewing angle is 0° perceived by the user, such that the brightness of each region of a whole display screen provided by the at least two display modules21may be consistent. In addition, a uniform display brightness may be realized without the need of adopting a flexible screen, that is, the display effect of the in-vehicle display device may be improved with the low cost.

In an embodiment, the at least two display modules may be arranged in sequence along the first direction on at least two rows to form a display module array.

Specifically, as shown inFIG.6,FIG.6is a schematic front view of the in-vehicle display device according to a second embodiment of the present disclosure. The at least two display modules21are arranged in sequence along the first direction D1on three rows, and a 3*3 display module array is obtained. The number of the rows of the display module array may be other numbers. The number of the display modules on each row may be three, five, or the like, which may be determined based on the actual need and is not limited herein.

Based on the above manner, the display screen having any area and including any number of display modules may be constructed to meet a diversified requirement and improve an applicability of the in-vehicle display device.

In an embodiment, the at least one user side-view display module may include a first side-view display module and a second side-view display module. A width of the first side-view display module is less than a width of the second side-view display module along the first direction, a first offset distance of the first side-view display module is less than a second offset distance of the second side-view display module, and the first offset distance is a distance between the first side-view display module and one of the at least one the user front-view display module and the second offset distance is a distance between the second side-view display module and the one of the at least one user front-view display module.

Specifically, the first side-view display module and the second side-view display module may be any two user side-view display modules satisfying a preset condition among all the user side-view display module212. In some embodiments, the preset condition may be that the width of the first side-view display module is less than the width of the second side-view display module along the first direction, and the first offset distance of the first side-view display module is less than the second offset distance of the second side-view display module.

As shown inFIG.7,FIG.7is a schematic front view of the in-vehicle display device according to a third embodiment of the present disclosure. The user side-view display module212adjacent to the user front-view display module211may be the first side-view module, and the user side-view display module212spaced from the user front-view display module211with a display module may be the second side-view display module.

It can be seen fromFIGS.4-5that a slope of the curve of the brightness proportion perceived by the user may be increased with a decrease of the absolute value of the viewing angle. Therefore, a change in the brightness proportion perceived by the user caused by an increase of an offset distance when the viewing angle is less (that is, when a distance between the user and the user front-view display module211is closer) may be greater than a change in the brightness proportion perceived by the user caused by an increase of the offset distance when the viewing angle is greater (that is, when the distance between the user and the user front-view display module211is farther).

Based on the above manner, the width of the display module closer to the user front-view display module211in the first direction D1may be less, and the width of the display module farther from the user front-view display module211in the first direction D1may be greater, such that a brightness difference between adjacent ones in multiple display modules closer to the user front-view display module211perceived by the user may be less. In this way, a brightness transition among the display modules closer to the user front-view display module211perceived by the user may be smoother, so as to further improve the display effect of the in-vehicle display device.

In some embodiments, the at least two display modules may be arranged in sequence along the first direction on at least two rows to form a display module array.

In each user side-view display module locating in a different row from the user front-view module, the width of the first side-view display module is less than the width of the second side-view display module along the first direction, a first horizontal offset distance of the first side-view display module is less than a second horizontal offset distance of the second side-view display module, and the first horizontal offset distance is a horizontal distance between the first side-view display module and one of the at least one the user front-view display module and the second offset distance is a horizontal distance between the second side-view display module and the one of the at least one user front-view display module.

Specifically, as shown inFIG.8,FIG.8is a schematic front view of the in-vehicle display device according to a fourth embodiment of the present disclosure. The at least two display modules21are arranged in sequence along the first direction D1on the three rows, and the 3*3 display module array may be obtained.

The first side-view display module and the second side-view display module may be any two user side-view display modules satisfying a preset condition and being not located on the same row with the user front-view display module211among all the user side-view display module212. In some embodiments, the preset condition may be that the width of the first side-view display module is less than the width of the second side-view display module along the first direction, and the first horizontal offset distance of the first side-view display module is less than the second horizontal offset distance of the second side-view display module.

Based on the above manner, the width of the display module closer to the user front-view display module211in the first direction D1may be less, and the width of the display module farther from the user front-view display module211in the first direction D1may be greater, such that the brightness difference between adjacent ones in multiple display modules closer to the user front-view display module211perceived by the user may be less. In this way, the brightness transition among the display modules closer to the user front-view display module211perceived by the user may be smoother, so as to further improve the display effect of the in-vehicle display device.

In some embodiments, a width of the user front-view display module along the first direction is greater than a horizontal width threshold, and/or a width of the user front-view display module along a third direction is greater than a vertical width threshold.

As shown inFIG.8, the third direction D4is substantially perpendicular to the first direction D1, and substantially parallel to a display surface of one of the at least one user front-view display module211.

Based on the above manner, a minimum value of the width of the user front-view display module211along the direction D1and a minimum value of the width of the user front-view display module211along the third direction D4may be limited, such that an area of the user front-view display module211may be equal to or greater than a preset area. The area of the user front-view display module211is configured to be large enough, such that a total number required for the at least two display modules21may be reduced and a difficulty of assembling the at least two display modules21may be reduced. In this way, the cost of the in-vehicle display device may be reduced while not reducing the display effect of the in-vehicle display device as much as possible.

An in-vehicle display device is provided in the present disclosure. As shown inFIG.9.FIG.9is structural schematic view of the in-vehicle display device according to an embodiment of the present disclosure. The in-vehicle display device30may include a processor31, a memory32, a bus33, and at least two display modules34, arranged in sequence along the first direction.

The processor31, the memory32, and at least two display modules34are connected to the bus33. The memory32may be configured to store program instructions. The processor31may execute the program instructions to implement the display controlling method in the above embodiments.

In the present embodiment, the processor31may also be referred to as a central processing unit (CPU). The processor31may be an integrated circuit chip with a capability of processing a signal. The processor31may also be a general-purpose processor, a digital signal processor (DSP), an application specific integrated circuit (ASIC), a field programmable gate array (FPGA) or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components. The general-purpose processor may be a microprocessor, or the processor31may be any conventional processor or the like.

Different from the prior art, according to the technical solution of the present disclosure, based on determining the user front-view module display module, the viewing angle corresponding to each user side-view display module may be determined based on the relationship between each user side-view display module and the user front-view display module and the relationship between each user side-view display module and the user position. When the at least two display modules are controlled or operated to display, the second brightness corresponding to each user side-view display module may be determined based on each viewing angle. All the second brightness may be greater than the first brightness of the user front-view display module. The user front-view display module may be controlled to display with the first brightness, and the user side-view display module may be controlled to display with the corresponding second brightness. That is, although the distance between the user side-view display module and the user position is greater than the distance between the user front-view display module and the user position, the user side-view display module may be controlled to display with the second brightness greater than the first brightness of the user front-view display module. In this way, the difference between the brightness of the user front-view display module and the brightness of the user side-view display module perceived by the user may be reduced or eliminated, such that the display brightness consistency of the in-vehicle display device using the flat screen may be improved, and the display effect of the in-vehicle display device may be improved with the low cost.

The non-transitory computer-readable storage medium40may store program instructions41.

When the at least two display modules are controlled or operated to display, the second brightness corresponding to each user side-view display module may be determined based on each viewing angle. All the second brightness may be greater than the first brightness of the user front-view display module. The user front-view display module may be controlled to display with the first brightness, and the user side-view display module may be controlled to display with the corresponding second brightness. That is, although the distance between the user side-view display module and the user position is greater than the distance between the user front-view display module and the user position, the user side-view display module may be controlled to display with the second brightness greater than the first brightness of the user front-view display module. In this way, the difference between the brightness of the user front-view display module and the brightness of the user side-view display module perceived by the user may be reduced or eliminated, such that the display brightness consistency of the in-vehicle display device using the flat screen may be improved, and the display effect of the in-vehicle display device may be improved with the low cost.

An in-vehicle display device is provided in the present disclosure, as shown inFIG.11.FIG.11is structural schematic view of the in-vehicle display device according to another embodiment of the present disclosure.
