Description

The invention relates to a display system and a method for operating a display system. A display with a display area on the outside of a motor vehicle is known from the publication DE 10 2018 217 653 A1. The publication DE 10 2006 015 724 A1 describes a heating system for an LCD display. A display device for a vehicle is known from publication US 2005 / 0046760 A1. Document US 2025 / 0008709 A1 describes a vehicle display device and a method for controlling it. A means of transport with a foldable or rollable display is known from publication DE 10 2021 131 343 A1. Against this background, the task was to operate a display panel appropriately for a vehicle. This problem is solved by a display system and a method with the features of the independent claims. Embodiments of the display system and the method are described in the dependent claims and the description. The display system according to the invention is designed for a vehicle, e.g., a motor vehicle, and comprises a flexible, elastically deformable and / or bendable display field, a climate control device for the display field, a mechanism, and at least one thermometer, wherein the display field, the climate control device, the mechanism, and the at least one thermometer are, or can be, arranged in an interior space of the vehicle. The mechanism is designed to move the display field between different positions, e.g., to shift it, and to bend a section of the display field at each position, thus dividing the display field into a curved section and at least one straight section. The at least one thermometer is designed to measure at least one temperature in the interior space of the vehicle.If at least one value of an air conditioning trigger function, which depends on the at least one measured temperature, deviates from a provided, usually adjustable, range of values ​​during a period of time, the air conditioning device is designed to automatically air condition the display field and change its temperature, i.e., to increase it if a value of the air conditioning trigger function is lower than the range of values, or to decrease it if the value of the air conditioning trigger function is higher than the range of values. The climate control device is designed as a flat surface. It comprises at least one climate control module, which includes at least one heating module, e.g., at least one surface heating module, designed to heat the display and increase its temperature. Alternatively or additionally, the climate control device may also include at least one cooling module, e.g., at least one surface cooling module, designed to cool the display and reduce its temperature. The display panel is moved by the mechanism relative to a component located in the vehicle's interior, moving into or out of the component. The display system includes a receptacle for the display panel, which is located in the component. The receptacle is designed to at least partially accommodate at least one internal section of the display panel that is movable by the mechanism, and the curved section is positioned at least partially inside and / or outside the receptacle, i.e., only inside, both inside and outside, or only outside. The climate control device and the receptacle, e.g., an inner wall of the receptacle, are in thermal contact.The at least one typically planar air conditioning module of the air conditioning device is arranged directly above and / or directly below the mounting for the display field. The at least one thermometer or temperature sensor of the display system located in the interior can be in direct thermal contact with the display field or its at least one section and can be located, for example, in the component or its housing for the display field, wherein the at least one thermometer is configured to directly measure the temperature of the at least one section. Alternatively or additionally, the at least one thermometer can be in indirect thermal contact with the at least one section, wherein the at least one thermometer is located outside the described component in the interior and is configured to measure a temperature in the interior of the vehicle, thereby indirectly measuring the temperature of the at least one section. The at least one thermometer can be located near the display field, usually in another component, e.g.,It may be located in or on an air conditioning unit, or in the interior. If the component is located in the interior, the thermometer located in the component is also located in the interior. The at least one thermometer is configured to directly or indirectly measure the temperature of the display field, or at least the temperature of a section, typically the section that is bent in the respective position. The at least one thermometer is usually arranged in and / or on the component in the immediate vicinity of a respective section of the display field. In one possible embodiment, the at least one thermometer is arranged at a fixed location on the component in the immediate vicinity of the section that is bent in the respective position, where the bent section is located independently of the respective position of the display field. The thermometer positioned at this location can touch or be in contact with the curved section. Since the display field is movable, the curved section is located at different positions along the typically strip-shaped display field depending on the orientation of the display field. The display system may include a control unit designed to detect and evaluate the at least one temperature measured by the at least one thermometer, to determine the air conditioning trigger function based on the values ​​of the at least one measured temperature, usually time-dependent values ​​for the air conditioning trigger function, and to compare these values ​​of the air conditioning trigger function with the value range provided for this purpose. The mechanism is designed to move the display and position it accordingly, while the climate control device is designed to climate-control the display in its respective position. The mechanism can move the display, for example, by shifting it, typically back and forth, and synchronously climate-control it by the device. Different sections of the moving display, which can be inserted into or removed from the component, are climate-controlled sequentially. If the display is thermally conductive, a change in the temperature of the section controlled by the climate control device can affect at least one other section of the display. The method according to the invention is designed for operating a display system for a vehicle, for example, for the interior of a vehicle designed as a motor vehicle. The display system comprises a flexible, elastically deformable and / or bendable display field, an air conditioning device, and at least one thermometer, which are arranged in the interior of the vehicle. The display field is moved between different positions, with a section of the display field being bent in each case. At least one temperature in the interior of the vehicle is measured by the at least one thermometer. If at least one value of an air conditioning trigger function, which depends on the at least one measured temperature, deviates from a defined range of values ​​for a period of time, the display field is automatically air-conditioned by the air conditioning device, and its temperature is changed. The display is cooled by the climate control device when a maximum value of the climate control trigger function exceeds a predefined maximum threshold that limits the upper range of values. Alternatively or additionally, the display is heated by the climate control device when a minimum value of the climate control trigger function falls below a predefined minimum threshold that limits the lower range of values. These thresholds, which are usually adjustable, limit the range of values ​​available for the climate control trigger function. The values ​​of the climate control trigger function can be temperature values. This is, for example,This is the case if the value of the air conditioning trigger function corresponds to at least one measured temperature, where the maximum value of the air conditioning trigger function corresponds to a measured maximum temperature and the minimum value of the air conditioning trigger function corresponds to a measured minimum temperature. Alternatively or additionally, it is provided that each value of the air conditioning trigger function depends on at least one temperature value, e.g., several temperature values, measured sequentially during the time period. The measured temperature values ​​can be summed and / or integrated to provide the air conditioning trigger function, whereby at least one value of the air conditioning trigger function for the time period is determined from several measured values ​​and / or compared with the designated range of values. It is also possible to determine an average temperature value from several temperature values ​​measured during the time period as the value of the air conditioning trigger function and compare it with the designated range of values. The display panel can be moved by the mechanism while it is being air-conditioned by the air-conditioning device, whereby different sections of the display panel moving relative to the air-conditioning device can be air-conditioned uniformly one after the other. The temperature of at least one section and / or the display field is measured directly by the at least one thermometer when it is in contact with the display field and, in a given configuration, is arranged on the display field. Alternatively or additionally, the temperature of the at least one section and / or the display field is measured indirectly by the at least one thermometer when the at least one thermometer is arranged separately from the display field inside the device. The procedure can be carried out while the vehicle is in motion or while stationary, if it is typically left standing for an extended period of several hours, days, or weeks. If the display is subjected to significant heating or cooling due to external influences over a prolonged period, it will be automatically climate-controlled, even when the vehicle is stationary, provided the value of the temperature-dependent climate control trigger function deviates from its intended range. In this process, the display that has been excessively heated by external influences will be cooled, or the display that has been excessively cooled by external influences will be heated. In this configuration, the control unit measures time and thus also a specific time period, storing and evaluating the measured temperature values. An application (app) runs as software within the control unit, calculating the values ​​for the climate control trigger function. The display is automatically climate-controlled if at least one value of the climate control trigger function deviates from the designated value range during the specified time period. Furthermore, the display field is designed to be touch-sensitive and can be configured and / or referred to as a touch display. The display field can be manually operated in any section outside the frame, i.e., in both the flat, straight section and the curved section. The mechanism for moving and deforming the display field is located in the component outside the display field. The display panel is heated by at least one heating module of the air conditioning device to protect against excessively low temperatures and alternatively cooled by at least one cooling module of the air conditioning device to protect against excessively high temperatures. The flat air conditioning device has at least one air conditioning module as the at least one heating module and / or as the at least one cooling module, wherein this at least one air conditioning module, usually flat, is arranged above and / or below the display field, e.g. above and / or below the receptacle for the display field, wherein in an embodiment it is arranged congruently with the receptacle. In this configuration, the climate control device is separated and / or isolated from the display panel. In cold conditions, at least one heating module is activated, and in hot conditions, at least one cooling module is activated, with the temperature of the display panel being set to a predetermined target value within the specified range. The climate control device for the display panel is powered by the vehicle's battery. The process is only executed, and the display panel automatically cooled, when the battery contains a level of electrical energy exceeding a predefined minimum threshold. Otherwise, automatic climate control of the display panel is disabled if the battery is deeply discharged. Climate control of the display panel according to the described method extends its lifespan. The at least one heating module can, for example, incorporate an electrical resistor. The at least one cooling module can incorporate a cooling plate. In this configuration, the control unit measures time and thus also a specific time period, storing and evaluating the measured temperature values. An application (app) runs as software within the control unit, calculating the values ​​for the climate control trigger function. The display is then automatically climate-controlled (heated or cooled) if at least one value of the climate control trigger function deviates from the designated value range during the specified time period. It is understood that the features mentioned above and those to be explained below can be used not only in the combinations specified, but also in other combinations or on their own, without leaving the scope of the present invention. The invention is schematically illustrated with reference to embodiments in the drawing and is described schematically and in detail with reference to the drawing. Fig. 1 shows a schematic sectional view of an embodiment of the display system according to the invention when carrying out an embodiment of the method according to the invention. Fig. 1 shows a schematic sectional view of a component 2, which is arranged here in the interior of a vehicle designed as a motor vehicle. The embodiment of the display system according to the invention comprises a strip-shaped, flexible and bendable display field 4, a thermometer 6, a control unit 8, a receptacle 10 for the display field 4 arranged in the component 2, an air conditioning device 18 for the display field 4 arranged in the component 2, and a mechanism (not shown) which is arranged here in the component 2 and moves the display field 4 back and forth when the embodiment of the method according to the invention is carried out. The component 2 is designed here as a control panel. The display field 4 is deformed depending on the movement performed and dynamically divided into three sections 12, 14, 16: a first external section 12, located outside the receptacle 10; a second internal section 14, located inside the receptacle 10; and a third curved section 16 between the external section 12 and the internal section 14. The external section 12 and the internal section 14 are each straight and / or planar. When the display panel 4 is moved, it is pushed upwards by the mechanism and moved out of the receptacle 10. In doing so, the internal section 14 is partially pushed out of the receptacle 10. The external section 12 is also enlarged outside the receptacle 10. The curved section 16 of the display panel 4 is also moved along the display panel 4, whereby, due to a change in position, the display panel 4 is now subjected to a greater load in a different curved section 16 due to a corresponding bending, than either of the other two straight sections 12 and 14. Furthermore, it is possible for the mechanism to push the display panel 4 downwards or into the receptacle 10. Furthermore, the thermometer 6 measures the temperature of the display field 4, or at least the temperature of the respective curved section 16 and / or a straight section 12, 14 inside or outside the recess 10, and this measurement is evaluated by the control unit 8 over time. If it is determined that at least the respective curved section 16 and / or at least one straight section 12, 14 has a temperature in a given position that is lower than a specified maximum threshold, the climate control device 18 is activated by the control unit 8 and the display field 4 is automatically heated by the climate control device 18. Conversely, if the temperature in that position is higher than a specified maximum threshold, the climate control device 18 is activated by the control unit 8 and the display field 4 is automatically cooled by the climate control device 18. It is also possible that the display field 4 is automatically climate-controlled, i.e., either cooled or heated, if, during a specified period of time, a climate control trigger function, which depends on the time and a temperature profile measured during that period, is greater than a specified maximum threshold or less than a specified minimum threshold. The display panel 4 can be moved by the mechanism and arranged in different positions. Depending on the position, the climate control device 18 climate-controlled (i.e., heated or cooled) different sections 12, 14, 16 of the display panel 4, with each section 12, 14, 16 being climate-controlled in its respective position. A given section 12, 14, 16 of the display panel 4 can also be climate-controlled while and / or when it is being moved.
