Definitions
- the invention relates to a display unit and a control unit with such a display unit.
- Such display units or control units can in particular in
- Motor vehicles are used to display information and to operate vehicle functions.
- the invention relates to a display unit.
- the display unit has a display element, by means of which in particular information can be displayed in a known manner.
- the display unit has a backlight, which can be used, for example, to generate light for better readability of the display element.
- the display unit has a back plate. The backlight is arranged between the display element and the back plate.
- the back plate is designed as a die-cast part.
- the back plate is preferably designed as a heat-dissipating element.
- heat which is generated, for example, by the backlight or by other components, can advantageously be dissipated from the display unit.
- the back plate can be made of a heat-conducting material and / or connected to heat-dissipating components.
- the back plate can in particular be designed as a stabilizing element. This can mean, for example, that the back plate completely or at least essentially ensures the stability of the entire display unit. As a result, a particularly high level of stability can be dispensed with in other components of the display unit, which saves effort and installation space.
- a reflection element for light emitted by the backlight can be arranged between the backlight and the backplate.
- light of the backlight can advantageously be directed forward where it serves to support the reading.
- the backlight is preferably configured to emit visible light. This can be used in particular so that a user can read the display unit more easily.
- the backlight is preferably alternative or additionally configured to emit invisible light. This invisible light can be used in particular in the context of a proximity sensor. The approach of an object such as a finger to the display unit can thus be detected, for example.
- the emission of visible light and the emission of invisible light can also be combined in particular.
- the invisible light can in particular be infrared light.
- the backlight has a plurality of surfaces which are different from one another and which are designed to emit invisible light independently of one another.
- a position of an object located in front of the display unit can be detected, in particular if the areas are controlled in a time-division multiplex method.
- This can mean, in particular, that only one of the surfaces emits light at predetermined time intervals in succession, so that when a reflected light is detected by a detector, the time before which of the surfaces an object is located can be recognized.
- the display unit preferably has a number of optical foils between the backlight and the display element. This allows various optical parameters to be set.
- the foils can be used, for example, to bring emitted light from light emitting diodes in one direction or polarization direction so that the light passes vertically through a display or display element located above it. This is advantageous in order to prevent color shifts for the human eye. Furthermore, light that is not in the correct polarization direction is preferably sent back from the foils to the reflection element and is radiated back here again. This allows more light to escape from the display.
- a film can be designed to make the light as diffuse as possible so that the display is illuminated homogeneously.
- Optical Parameters ie color shifts due to elements attached above the display, can be changed by selecting the LEDs so that a specified color space is created in the end. For example, a spectrum that tends to yellow light can be compensated for by light-emitting diodes that have a very high blue component. This is called color class selection.
- the display unit preferably has a cover plate, the rear plate and the cover plate together forming a complete closure of the display unit. This enables a particularly compact design and protection of all internal components through the cover plate and the back plate.
- the cover plate can in particular be optically transparent.
- the back plate carries all other elements. This enables particularly high stability and a compact design to be achieved.
- the display unit preferably also has a printed circuit board. This can, for example, electronic components
- the circuit board can in particular be attached to the back plate.
- the circuit board is preferably fastened to the rear plate by means of an adhesive tape. This has proven to be a simple and reliable design.
- the display element is preferably attached to the back plate by means of an adhesive tape.
- This adhesive tape can be arranged, for example, between the display element and the foils. For example, it can ensure dust tightness.
- the invention further relates to an operating unit.
- the control unit has a display unit according to the invention. All versions and variants described here can be used.
- the operating unit also has a proximity sensor for detecting a position of an object in front of the display unit. The advantages already mentioned above can be achieved by means of the control unit according to the invention.
- the proximity sensor can be used to detect when an object is approaching the operating unit, and a position of this object can preferably also be detected.
- the display unit in the control unit is preferably designed such that it can emit invisible light and / or that it has a plurality of different surfaces which are designed to emit invisible light independently of one another.
- the control unit also preferably has a number of receivers for the invisible light, which are part of the proximity sensor. A position of an approaching object such as a human finger can be recognized by means of these receivers, as has already been described above.
- the control unit is preferably configured to leave the proximity sensor active even when the display element is switched off. As a result, operation can also take place in a situation in which the display unit is not required. For example, an approach of a finger can also be recognized when the vehicle is switched off. This can be used, for example, to enable an occupant in the vehicle to perform various functions and / or, for example, to switch on the control unit in response to his finger approaching the control unit.
- the embodiment described here enables, for example, flexible integration of the functionalities of a display panel, proximity detection, lighting and a fixation concept.
- a die-cast part which can also be referred to as die-cast for example and which can act, for example, as a light box for the display panel, it is now possible to integrate the transmission side of the proximity sensor system. As a result, the reception side requires less effort for the light guide and has a significantly reduced space requirement.
- a display panel with a stack-up and light guide is typically transmissive even in the switched-off state for light in the infrared range and can therefore be used to generate a homogeneous transmission space for the proximity sensors.
- the necessary transmitters such as infrared LEDs, can be integrated in addition to the display backlight or background lighting.
- Proximity sensors and display panels can be optimally integrated.
- Existing light guides can be used several times and offer an optimization and enlargement of the homogeneous transmission field.
- back plate which is designed as a die-cast part or die-cast, and which acts as a light box for a display panel, it is now also possible to integrate the display, operating parts and instrument cluster into one unit.
- the rigidity of a display frame can be improved, which leads in particular to a better black screen homo genicity.
- the back plate can be used as a central element for this, which carries a display panel inserted using a plastic frame.
- a circuit board can be attached to the back of a housing. Flexibility can be guaranteed, for example, by using an adhesive tape or cushion tape between the printed circuit board and
- Back plate or between a display glass and a plastic frame are provided.
- the cast can be designed so that optimal heat dissipation to the back.
- a double-walled version can also be provided.
- a desired color location can be compared with this concept and the background lighting used, for example in the form of backlight LEDs.

- the control unit 10 also has a proximity sensor 20. This has a total of six infrared transmitters 30 and two infrared receivers 40. By a sequential control of the infrared transmitter 30 can be detected by means of the infrared receiver 40 in an advantageous manner when infrared light is reflected from a nearby object re. This also makes it possible to recognize where this object is located in front of the operating unit 10. It should be understood that the infrared transmitters could also be integrated into the display unit.
- FIG. 2 shows an exploded view of the display unit 100, which is part of the control unit 10 from FIG. 1.
- the display unit 100 has a back plate 110. This is designed as a die-cast part and ensures the stability of the entire display unit 100. This means in particular that all other components, which will be discussed below, derive their stability and position from the backplate 110.
- An adhesive 120 is applied to the back plate 110.
- a reflection element 130 is thus attached to the rear plate 110.
- a backlight 140 which is in the form of a light guide, is arranged further ahead.
- a circuit board 150 is assigned to this backlight 140. This is located below the backlight 140 and is attached to the back plate 110 by means of an adhesive tape, not shown separately.
- the circuit board 150 in particular provides supply and control functions and carries light-emitting diodes for illuminating the backlight 140.
- a further three optical foils 160 are attached further ahead, which are used for various optical tasks and in particular can adapt a displayed image.
- a display element 180 which is fastened to the rear plate 110 by means of an adhesive tape 170.
