Description

[Technical Field]

[0001] The present invention relates to the field of brightness adjustment of display devices, and in particular to a processing system capable of simultaneously presenting different sectional brightness representations on a single display screen. The present invention provides a means for adjusting the display screen of a single display device when it receives different degrees of visual light sensing intensity under various field, environment, time and installation conditions, thereby enabling the effective implementation of display applications that present a more visually pleasing screen brightness flexible representation even when viewed by the naked eye. [Background technology]

[0002] Display devices are now among the most mature electronic products, and their most direct function is, of course, to display information on a screen for human viewing. However, inappropriate display brightness can affect people's visibility. Generally, nits (nits) are widely used as a measurement standard to measure display device brightness. Common display devices typically have brightness values ​​ranging from 200 to 350 nits, although the specific value varies depending on the manufacturer and model. High-brightness display devices typically exceed 350 nits, making them suitable for use in bright environments such as outdoors or in places with intense backlighting. In addition, high-dynamic-range (HDR) display devices have even higher brightness capabilities, sometimes exceeding 1,000 nits. This high brightness level helps present a wider brightness range and provides more realistic images.

[0003] On the other hand, some display devices are designed with local dimming technology to eliminate design considerations for basic luminance and improve the contrast and black representation of the display device to provide more desirable image quality. Specifically, local dimming adjusts the backlight luminance to achieve different regional representations depending on the image content. For example, when a deep black needs to be displayed in a portion of the image, the luminance can be reduced in the appropriate backlight region to enhance the black representation. Similarly, when a bright white or high-brightness area needs to be displayed, the luminance can be increased in the appropriate backlight region to provide a more desirable luminance representation. In other words, local backlight control adjusts the backlight luminance determined by the image content to achieve different regions, thereby improving the contrast of the image. This means that the black representation in the image content is displayed darker and the white representation is displayed brighter. The color difference range between the darkest black and the brightest white makes the overall image content closer to the real world, and the backlight can be reduced to present more screen details, especially in dark-toned scenes.

[0004] However, even if a single display device has an adjustment function for brightness to adapt to factors such as different fields and environments, there is currently no function that can adjust brightness in sections on a single display device to provide a better display effect if the display screen has different light exposure levels. The aforementioned regional backlight control adjusts the brightness based on the content of the image information, thereby increasing the screen contrast and detail. In other words, the adjustment should be understood as "actively" creating corresponding changes depending on the content of the image information, and there is currently no technology that "passively" creates different levels of change by adjusting according to different light exposure levels after light exposure. For example, the screens of in-vehicle displays and head-up displays are both becoming larger and larger to facilitate driver viewing. However, due to the limited space inside the vehicle, the lower half of the display screen in the vehicle may visually sense insufficient ambient light intensity, while the upper half may be relatively bright. In this case, if the same brightness representation were to be displayed, the entire screen would be too bright or too dark, and would not be suitable for either the upper or lower display area. Meanwhile, display devices in different fields also have a variety of specifications and layouts. For example, display screen dimensions can vary from the basic 1:1 or 3:2 to 16:9, and it is not difficult to imagine applications in the future with special ratios that are narrower and longer. Given these various new display screen ratios and the simultaneous use by multiple people, technical means for displaying brightness representations according to different needs and objectives on the same display screen naturally arise. That is, technical means for instantly satisfying the different needs and objectives of different users through segmented brightness representations are provided. For example, a display device positioned across the windshield in a vehicle interior, corresponding to the driver's seat and passenger seat, can be a good example. Technical means for generating segmented brightness representations can be provided to instantly meet the needs of multiple users simultaneously and resolve the problem. Summary of the Invention [Problem to be solved by the invention]

[0005] In view of this, the present invention team has conceived and proposed a processing system that simultaneously presents different luminance representations on a single display screen, which uses a technical means to adaptively adjust the display luminance according to the difference in the degree of light exposure of the display area after receiving light, thereby eliminating the drawback of relatively poor visibility of the display screen caused by the uniform luminance representation of the entire screen under various different environmental conditions, time, etc.

[0006] The object of the present invention is to provide a single display device that, after installation, takes into consideration factors arising from various fields, environments, time, etc., and when the same display device screen experiences light sensitivity levels or usage conditions that result in significantly different intensities, such as when an in-vehicle display device has different light sensitivity levels after receiving light in the upper and lower regions due to its installation position or projection position, or when there are different visual needs in the left and right regions, or when a continuous display device that is attached to the exterior wall of a building and has curved corners forms different light receiving surfaces, the present invention provides a technical means for providing a sectional brightness expression that can adaptively adjust the visual sensitivity level of the single display device, and can provide a clear view of the entire screen of the display device to humans. [Means for solving the problem]

[0007] In order to achieve the above object, the present invention proposes a processing system for simultaneously presenting different sectional luminance representations on a single display device screen, comprising: a detection module for performing multi-point photometry on a preliminary imaging area provided for viewing after installation or projection of a display device to detect differences in ambient light intensity distribution presented at each point on the screen of the display device after the display device is installed; and an adjustment control module electrically connected to the detection module, wherein the adjustment control module installs and forms a plurality of modulation areas that are separated to correspond to the screen range of the display device according to the differences in ambient light intensity distribution presented in the preliminary imaging area, and presents a screen range of the display device that corresponds to relatively strong ambient light detection in the preliminary imaging area, and the adjustment control module adjusts and outputs the plurality of modulation areas to have a relatively high luminance display representation, and presents a screen range of the display device that corresponds to relatively weak ambient light detection in the preliminary imaging area, and the adjustment control module adjusts and outputs the plurality of modulation areas to have a relatively low luminance display representation.

[0008] More preferably, the adjustment control module realizes the plurality of modulation regions with a number of different brightness display expressions by adjusting one or a combination of an adjusted output current value and an adjusted output Gamma value for the plurality of modulation regions.

[0009] More preferably, the display device has at least one bend angle, so that the screen of the display device is not flush with the screen of the display device.

[0010] More preferably, the detection module further includes a manual trigger unit, which allows an external user to trigger the detection module via the manual trigger unit at any time to perform photometric operation.

[0011] More preferably, the detection module further includes a timed trigger unit, which is used by an external user to set at least one trigger time through the timed trigger unit, so that when the trigger time is reached, the detection module is activated to perform photometric operation.

[0012] More preferably, the detection module further includes a light / dark trigger unit, which is used by an external user to set at least one environmental trigger brightness through the light / dark trigger unit, so that when the environmental trigger brightness is reached, the detection module is activated to perform photometric operation.

[0013] More preferably, the screen range of the display device is set to a plurality of photosensitive elements, and the ambient light intensity presented by each of the photosensitive elements and its neighboring photosensitive elements is determined, and the photosensitive element presenting a relatively strong ambient light intensity is divided by the photosensitive element presenting a relatively weak ambient light intensity to obtain a multiplication relationship, and when the multiplication relationship is greater than or equal to a predetermined multiplication condition, a dividing section is defined and formed between two photosensitive elements corresponding to two adjacent photosensitive elements among the plurality of photosensitive elements that satisfy the predetermined multiplication condition, and at least one dividing line formed continuously on the plurality of dividing sections divides the screen range of the display device to form the plurality of modulation areas. More preferably, the predetermined multiplication condition is greater than or equal to 1.2, and the area having a certain degree of light sensing difference can be divided accordingly.

[0014] Furthermore, based on a similar technical concept, the present invention also proposes a processing system for simultaneously presenting different sectional luminance representations on a single display device screen, comprising: a detection module for searching the direct viewing ranges of the driver's position and the assistant driver's position for an auxiliary imaging area installed in a vehicle of a display device; and an adjustment control module electrically connected to the detection module, wherein the adjustment control module divides the auxiliary imaging area according to the direct viewing ranges of the driver's position and the assistant driver's position and along the X-axis direction to correspond to the screen range of the display device, thereby installing and forming a first modulation area corresponding to the direct viewing range of the driver's position and a second modulation area corresponding to the direct viewing range of the assistant driver's position, and wherein the adjustment control module controls the first modulation area to have a first luminance display representation and the second modulation area to have a second luminance display representation different from the first luminance display representation using one or a combination of an adjusted output current value and an adjusted output Gamma value for the first modulation area and the second modulation area.

[0015] More preferably, the adjustable luminance range of the first luminance display representation is greater than the adjustable luminance range of the second luminance display representation. [Effects of the Invention]

[0016] In summary, the processing system for simultaneously presenting different sectional luminance representations on a single display device of the present invention can solve the drawback of various display devices, in which the display screen of the single display device varies depending on the light receiving level and usage conditions due to factors such as the field, environment, time, and installation environment, making it difficult to observe with the naked eye. The present invention adaptively adjusts the display device to form sectional luminance representations for different light receiving areas with different levels, thereby achieving a display effect in which the screen area of ​​the display device exhibiting relatively strong ambient light sensing is adjusted to have a relatively high luminance, and the screen area of ​​the display device exhibiting relatively weak ambient light sensing is adjusted to have a relatively low luminance. Furthermore, using a similar technical concept, a display screen installed in the front seat of a vehicle can automatically adjust to form sectional luminance representations based on the differences in the positions and usage needs of the driver and the driver's assistant, and further provides a wider range of luminance representation variation for the driver's position. Furthermore, even in special applications, such as display devices with bendable characteristics, where the screen's light reception level varies after installation, it is possible to easily achieve display effects by adjusting the luminance representation of the seg- ments. Additionally, by varying the current value, gamma value, or a combination thereof, the luminance representation of the seg- ments can be significantly increased, providing the flexibility to adjust the luminance representation, for example, by cutting out a relatively large number of modulation sections with different intensities. Furthermore, the light reception level of a single display device inevitably varies depending on factors such as time, field, and environment. This is not a fixed, unchanging level. For example, there are differences between day and night, sunny and cloudy weather, and in mobile display devices, such as in a vehicle display device, there are differences between indoors and outdoors, such as in a tunnel. All of these factors can cause changes in the original light reception level of the display device. Therefore, adaptive re-measurement is necessary to achieve better display effects. The manual trigger unit, scheduled trigger unit, or light / dark trigger unit of the present invention allows for more flexible and precise dynamic adjustment of the display device, resulting in better display effects.In the present invention, by using an original dividing technique, dividing lines can be obtained to divide flexibly according to the set relationship, and a single display device can be formed into two or more modulation areas, and thus, by utilizing this multi-dimensional dividing and adjustment, the display device can present an extremely good visibility display.

DETAILED DESCRIPTION OF THE INVENTION

[0018] The contents of the present invention will be clearly understood by those skilled in the art from the following description, taken in conjunction with the accompanying drawings. It should be noted that the dimensions, ratios, sizes, shapes, application states, etc. of the structures shown in the drawings are merely for illustrative purposes of the technical features of the present invention and do not represent actual structural designs.

[0019] 1 to 4, 5, and 6, which respectively show a system functional block diagram of a preferred embodiment of the present invention, a system functional block diagram of another embodiment, a schematic diagram of a region where a display device's preliminary installation position is used as a preliminary imaging region, and a schematic diagram of modulation region segmentation, as well as a schematic diagram of a preliminary imaging region of an in-vehicle direct-view display device according to a preferred embodiment of the present invention, and a schematic diagram of a preliminary imaging region of an in-vehicle head-up display device. As can be seen from the figures, the processing system for simultaneously presenting different segment luminance representations on a single display screen provided by the present invention comprises a detection module 1 and an adjustment control module 2. The detection module 1 performs multi-point photometry on a preliminary imaging region 80, which is provided for viewing by presenting a screen in a direct-view manner at the planned installation position of the display device 9 (see FIG. 5) or by presenting a screen in a projection manner after installation (see FIG. 6), thereby detecting the difference in ambient light intensity distribution presented at each point provided for actual viewing corresponding to the screen of the display device 9 after installation. Accordingly, by detecting the corresponding position where the screen is to be displayed, i.e., by detecting the difference in the ambient light intensity distribution in advance for the preliminary imaging area 80, it is possible to determine in advance the degree of the possible ambient light influence that the user may immediately experience when viewing some areas, and then to further adjust the brightness of the areas, allowing the user to view and obtain information that will improve the visibility of the entire display screen.

[0020] Furthermore, after the detection module 1 detects the difference in ambient light intensity distribution in the preliminary imaging area 80, the adjustment control module 2 electrically connected to the detection module 1 is used to install and form a plurality of modulation areas 20 that are cut out to correspond to the screen range of the display device 9 according to the difference in ambient light intensity distribution presented in the preliminary imaging area 80, and among them, a screen range of the display device 9 corresponding to relatively strong ambient light detection is presented in the preliminary imaging area 80, and the adjustment control module 2 adjusts and outputs the plurality of modulation areas 20 to have a relatively high brightness display representation, and a screen range of the display device 9 corresponding to relatively weak ambient light detection is presented in the preliminary imaging area 80, and the adjustment control module 2 adjusts and outputs the plurality of modulation areas 20 to have a relatively low brightness display representation. For example, in actual driving experience, a display device such as a navigation information display device, which is often installed in a vehicle, may not cause the driver difficulty in viewing the display when driving at night or in an underground parking lot. However, once driving under the bright sun, the brightness is obviously insufficient, making it difficult to view clearly, and in serious cases, road safety may be seriously affected. For the same reason, in more accurate actual situations, there may be similar problems caused by differences in the degree of light reception that exist in various environments. For example, when the size of the interior space of a vehicle is limited and there is a clear difference in the degree of ambient light reception above and below the display screen of an in-vehicle direct-view display device or a head-up display device, there is no deficiency at all. In this case, if the brightness of the entire display device is adjusted too high, the dark areas of the display screen may be too bright or the bright areas of the display screen may be too dark. Therefore, the processing system for simultaneously presenting different luminance representations on a single display screen of the present invention can effectively adjust the intensity difference caused by direct illumination of the preliminary imaging area 80 or the irregular light reception caused by shielding or obscuration, which may affect the user's viewing experience. Referring again to Figure 7, it is a schematic diagram of a preliminary imaging area mounted on the exterior wall of a building in accordance with a preferred embodiment of the present invention.For example, in the case of a single display device on the exterior wall of a building with special bending characteristics, the display device 9 has at least one bending angle 91, which causes the screen of the display device 9 to be not on the same plane, which may result in different orientations due to the light receiving surface, resulting in obvious differences in the level of light reception.In this case, different zonal luminance representations should be naturally provided to observers facing different directions, thereby increasing versatility.In addition, the subject of zonal luminance representation adjustment in this invention refers to the screen displayed on a single display device, and in applications where images are stitched together via multiple display devices, this is not the subject that the present invention naturally addresses.In general, in such installations where multiple display devices are stitched together, each display device can essentially adjust its screen output independently, without the need for any special technical means.

[0021] Furthermore, the preliminary imaging area 80 can exhibit multiple ambient light intensity distribution differences, such as multiple stepped areas or inconsistent distance differences between the intensities. To conveniently adjust various segment brightness expressions, the adjustment control module 2 adjusts the output current and / or output gamma value of each of the modulation areas 20 to realize multiple brightness display expressions for the modulation areas 20. For example, it is also preferable to adjust the same current value with different gamma curves, or the same gamma curve with different current values, or both simultaneously to control the brightness output.

[0022] Taking into consideration the multiple environmental light intensity distribution differences that may actually exist in the preliminary imaging area 80, the present invention uses an original cutting technique to cut and form the multiple modulation areas 20, and uses the detection module 1 to cut out the preliminary imaging area 80 so that each of the multiple modulation areas 20 becomes a multiple number of photosensitive elements 801, for example, in a grid pattern. Next, the adjustment control module 2 cuts out the screen range of the display device 9 to correspond to the plurality of photosensitive elements 801, in other words, the plurality of photosensitive elements 801 and the plurality of photosensitive elements 201 have a completely one-to-one correspondence, and the detection module 1 determines the ambient light intensity presented by each of the plurality of photosensitive elements 801 and the other plurality of photosensitive elements 801 adjacent to each other, and divides the photosensitive element 801 presenting a relatively strong ambient light intensity by the photosensitive element 801 presenting a relatively weak ambient light intensity to obtain a multiplication relationship, whereby when the multiplication relationship is greater than or equal to a predetermined multiplication condition, the adjustment control module 2 defines and forms a dividing section 21 between the two photosensitive elements 201 corresponding to the two adjacent photosensitive elements 801 among the plurality of photosensitive elements 801 that satisfy the predetermined multiplication condition. For example, if the intensity ratio of the light received by a given photosensitive element 801 compared to the adjacent photosensitive elements 801 is 10:1:8:9:7, and the predetermined multiplication factor is set to 2, the multiplication factors are 10, 1.25, 1.111, and 1.429, respectively. Therefore, the separation section 21 is formed only between the two dimming elements 201 corresponding to the two 10:1 photosensitive elements 801. The predetermined multiplication factor, i.e., the degree of separation sensitivity of the brightness difference, is the set value of the critical condition that allows separation only when the difference is relatively large or relatively small. Subsequently, the screen area of ​​the display device 9 is separated by at least one separation line 210 formed continuously on the plurality of separation sections 21, thereby forming the plurality of modulation regions 20.Wherein, the predetermined multiple condition may be set to be greater than or equal to 1.2, so as to perform the separation with a relatively high degree of agility, thereby realizing a more precise screen dimming screen presentation.

[0023] Furthermore, the display device 9 inevitably experiences changes in its light reception level due to factors such as different times, fields, and environments, and is not fixed and unchanging. For example, there are differences between day and night throughout the day, or differences in the weather such as sunny or cloudy weather with different levels of sunlight as a weather factor, or there are differences caused by changes in the environment. For example, in the case of an in-vehicle display device with mobile characteristics, there are differences in the light reception level between indoor locations such as tunnels and parking lots and outdoor spaces, and all of these can cause changes in the original light reception level of the screen of the display device 9. Therefore, in order to achieve a better display effect, it is necessary to adaptively re-measure the light. According to this, the detection module 1 may further include a manual trigger unit 12, through which an external user can activate the detection module 1 for photometry operation at any time; or the detection module 1 may further include a timed trigger unit 14, through which an external user can set at least one trigger time, so that the detection module 1 can be activated for photometry operation when the trigger time is reached; or the detection module 1 may further include a light / dark trigger unit 16, through which an external user can set at least one environmental trigger brightness, so that the detection module 1 can be activated for photometry operation when the environmental trigger brightness is reached. Accordingly, the manual trigger unit 12, the timed trigger unit 14, or the light / dark trigger unit 16 of the present invention can dynamically adjust the luminance representation of the display device 9 in a more adaptive manner, thereby providing a better display effect.

[0024] 1 and 8, Fig. 8 is a schematic diagram of a first modulation area and a second modulation area formed by dividing the area so as to correspond to the driver's and assistant driver's positions of an in-vehicle display device in yet another embodiment of a preferred embodiment of the present invention. Based on the technical concept of sectional luminance representation formed on a single display screen, the present invention also discloses a processing system for simultaneously presenting different sectional luminance representations on a single display screen, and the processing system also includes the detection module 1 and the adjustment control module 2. In this embodiment, the detection module 1 is used to search for the direct viewing ranges of the driver's and assistant driver's positions in an auxiliary imaging area 80 of the display device 9 installed in the vehicle. The adjustment control module 2 is electrically connected to the detection module 1, and the adjustment control module 2 divides the preliminary imaging area 80 according to the direct viewing ranges of the driver's position and the assistant driver's position and along the X-axis direction to correspond to the screen range of the display device, thereby forming a first modulation area 202 corresponding to the direct viewing range of the driver's position and a second modulation area 203 corresponding to the direct viewing range of the assistant driver's position, where the adjustment control module 2 controls the first modulation area 202 to have a first luminance display expression and the second modulation area 203 to have a second luminance display expression different from the first luminance display expression according to one or a combination of an adjusted output current value and an adjusted output Gamma value for the first modulation area 202 and the second modulation area 203. In this way, the first modulation area 202 and the second modulation area 203 of the display device 9 can be configured to have the different first luminance display expression and the second luminance display expression according to the difference in viewing needs of the driver and the assistant driver. The aforementioned search for the direct viewing range refers to obtaining the approximate viewing range of the driver and assistant driver when observing directly using a computer simulation method based on the reasonable vehicle dimensions and the reasonable approximate layout of the interior space, such as parameter conditions such as the distance between the left and right sides, the distance between the seat and the windshield, and the average height of an adult.Of course, this does not mean that adaptability cannot be subsequently adjusted again according to actual applications, for example, after dividing and forming the first modulation area 202 and the second modulation area 203, various parameters can be input again, such as the actual heights of the driver and the assistant driver, and the seat positions that the driver and the assistant driver are accustomed to, to re-simulate and change the first modulation area 202 and the second modulation area 203, thereby adjusting the division state appropriately according to the actual driver and riding habits, etc. To explain in detail the difference in brightness expression, in a specific application situation, the first modulation area 202 at the driver's position is provided for the driver's observation who operates the vehicle, and therefore, in addition to the need for clarity of the display screen, safety considerations are also taken into account, while the second modulation area 203 at the assistant driver's position is mainly provided for the passenger's observation, and therefore, safety considerations are not taken into account, so the areas can be divided accordingly on the display to form different brightness expressions.

[0025] Furthermore, the adjustable brightness range of the first luminance display expression is larger than that of the second luminance display expression, and therefore the first modulation area 202 corresponding to the driver's position has a relatively large brightness change range, allowing the first luminance display expression to be adjusted to an appropriate state at any time under various circumstances, allowing the driver to observe a clear display screen under various circumstances and ensuring safety during driving.As mentioned above, it is more difficult for a passenger in the front passenger seat to observe and operate the screen while driving a vehicle, which may endanger safety, so the adjustable brightness range of the second luminance display expression may be smaller than that of the first luminance display expression.

[0026] In summary, the processing system for simultaneously presenting different sectional luminance representations on a single display device of the present invention can effectively solve the drawback of various display devices, in which the background of the display screen of the single display device varies depending on the light receiving level or the viewing needs vary, making it difficult to observe with the naked eye, due to factors such as the field, environment, time, and installation surroundings. The present invention adaptively adjusts the display device to form sectional luminance representations for different light receiving areas with different levels, depending on the usage needs and circumstances, thereby achieving a display effect in which a screen area of ​​the display device that exhibits relatively strong ambient light sensing is adjusted to have a relatively high luminance, and a screen area of ​​the display device that exhibits relatively weak ambient light sensing is adjusted to have a relatively low luminance. Based on this, even in special applications, for example, when a display device with bending characteristics is installed, the screen will receive different amounts of light, so it is possible to easily adjust the display effect by using segmented brightness expression, or when used in a vehicle, the display screen of a single display device can be segmented according to the driver's position and the driver's assistant's position, and then different brightnesses can be presented, thereby ensuring clear observation and traffic safety. In addition, by changing the current value, gamma value, or a combination thereof, it is possible to obtain adjustment flexibility that can greatly increase the segmented brightness expression, for example by segmenting a relatively large number of modulation sections with different intensities. Furthermore, it is inevitable that the degree of light reception of a single display device will change depending on factors such as time, field, and environment, and it is not fixed and unchanging. For example, there are differences between daytime and nighttime, and between sunny and cloudy weather. In the case of a display device with mobility characteristics, for example, in the case of an in-vehicle display device, there are differences between indoors and outdoors, such as in a tunnel, and all of these can cause changes in the degree of light reception of the original screen of the display device. Therefore, in order to obtain a better display effect, it is necessary to adaptively re-measure the light.The manual trigger unit, the time trigger unit, or the light / dark trigger unit of the present invention can more flexibly and precisely adjust the dynamics of the display device, resulting in a better display effect.In the present invention, by using an ingenious dividing technology, dividing lines can be obtained to divide flexibly according to the set relationship, and a single display device can be formed into two or more modulation areas, and thus the display device can present an excellent visibility display by utilizing the multiple dividing and adjustment.
