Description

Technical Field

[0001] This invention relates to a display device and a vehicle display system including the same. Specifically, this invention relates to a display device having a knob partially disposed on a display area and a vehicle display system including the same. Prior Technology

[0002] Touchscreens have become the mainstream interface for many smart display devices, such as mobile phones, in-vehicle systems, home appliances, and other electronic products. However, compared to traditional physical buttons, touchscreens lack the tactile feedback and differentiation of buttons. Users often need to look at the screen to pinpoint the exact location of the buttons during operation. If users are operating the touchscreen while performing other activities, such as walking or driving, they must shift their gaze to confirm the button positions, thus reducing the convenience and safety of smart display devices.

[0003] Therefore, some touch display devices still feature physical buttons for functions that often require blind operation, such as volume buttons on smartphones and air conditioning knobs on car dashboards. However, compared to the diverse designs and display switching capabilities of touchscreens, the placement of these physical buttons is relatively monotonous, often increasing bezel width or occupying display area, thus reducing aesthetics and functionality. Therefore, improving the combination design of touchscreens and physical buttons / knobs to achieve better functionality and customization is a problem that needs to be solved in this field. Summary of the Invention

[0004] The present invention provides a display device comprising a knob arranged across a display area and a non-display area, wherein only one of the plurality of sensors in the knob is detected by the touch screen at any given time, thereby achieving the purpose of increasing panel functionality and tactile versatility and simplifying the design of the detection mechanism.

[0005] The present invention also provides a vehicle display system, which includes a display device with a knob arranged across the display area and the non-display area, to provide vehicle users with diverse tactile feedback when operating the system and to increase the design variability of the display system.

[0006] The display device includes a touch screen and a knob. The touch screen has a first area and a second area, wherein the first area has a touch surface, and the second area is disposed on at least one side of the first area and lies on an extension plane of the touch surface. The knob is at least partially disposed on the first area and the remainder on the second area, is rotatable relative to the touch screen, and includes a plurality of sub-segments arranged adjacent to each other in an angular direction; the knob includes at least two sensors disposed close to the touch screen, and each sub-segment includes at most one sensor. The touch screen can detect the position of the sensors, and only one sensor can be located on the first area at a time.

[0007] On the other hand, the vehicle display system includes the aforementioned display device, and the vehicle display system is located on the control console in the vehicle. Simple Explanation of the Diagram

[0021] As shown in Figures 1 and 2, in one embodiment, the display device includes a touch screen 100 and a knob 200. The touch screen 100 has a first area 110 and a second area 120, wherein the first area 110 has a touch surface 111, and the second area 120 is disposed on at least one side of the first area 110 and is located on an extension plane of the touch surface 111. The knob 200 is at least partially disposed on the first area 110 and the remaining portion is disposed on the second area 120, i.e., it is disposed across the boundary between the first area 110 and the second area 120; the knob 200 is rotatable relative to the touch screen 100, and its rotation axis X is perpendicular to the plane where the touch surface 111 is located. As shown in Figure 3, the knob 200 also includes a plurality of sub-segments 210 disposed adjacently in the angular direction. The rotation of the knob 200 corresponds to the segmentation of the sub-segments 210. For example, when there are four sub-segments 210, each segment of the knob 200 can rotate a quarter turn (i.e., the minimum rotation angle is 90°). In other words, the sub-segments 210 rotate together with the knob 200 and switch between different angular positions. After rotating for a period of time, the projection position of the sub-segment 210 on the touch screen 100 coincides with the position of the adjacent sub-segment 210 before rotation. Here, the sub-segment 210 is a virtual or physical area defined for the convenience of design and explanation, and its configuration can correspond to the position of other components on the knob 200. For example, in some embodiments, the knob 200 includes a plurality of tactile generating parts (not shown) arranged separately in the angular direction. Each sub-segment 210 may be located between adjacent tactile generating parts, but is not limited thereto. When the knob 200 is rotated, the tactile generating parts rotate together to the adjacent angular position and provide tactile feedback, such as rebound or resistance.

[0022] Additionally, the knob 200 includes at least two detectors 220, which can be positioned close to the touchscreen 100. Each sub-segment 210 includes at most one detector 220, meaning each sub-segment 210 may contain a complete detector 220 or no detector 220. The area of ​​each detector 220 is smaller than the area of ​​the sub-segment 210 in which it resides. The touchscreen 100 can detect the positions of these detectors 220, corresponding to any angular positioning, with only one detector 220 located on the first area 110. In some embodiments, the first area 110 may include multiple sensing units. When a detector 220 is located on the projection of one or more sensing units, the sensing units generate electrical signals to determine the position of the detector 220 and correspond it to one of the rotation segments. For example, in one embodiment, the area and position of the sensing unit can correspond to the projection of the sub-segment 210 onto the first region, such that at any angle of the knob 200, a sub-segment 210 containing the detector 220 is located on one of the sensing units; conversely, the area and position of the sensing unit can be used to define the range of the sub-segment 210. In another embodiment, the sub-segment containing the detector 220 can cover multiple sensing units, and the detector 220 is located on one or more of the sensing units, but is not limited thereto.

[0023] Specifically, the first area 110 can be a display area, such as a touch-sensitive display panel, which can detect the user's rotation of the knob or direct touch of the touch surface 111 to generate an operation signal; the second area can be a non-display area, such as a bezel or decorative panel, which may contain a different surface material or texture than the first area 110, and may be equipped with additional mechanical components, such as buttons or indicator lights, as control elements that work in conjunction with the display area or operate independently. According to the above configuration, the knob 200, as a protruding mechanical structure, provides tactile differentiation, and the knob 200's location at the boundary between the display and non-display areas also helps the user locate the knob 200 by perceiving the different materials of the two areas. Furthermore, the knob 200 has segmented rotation, corresponding to changes in functional parameters, allowing the user to conveniently operate the selected function without directly looking at the screen.

[0024] In the embodiment shown in Figure 3, the knob 200 includes two detectors 220, located on opposite sides of the knob 200. The knob 200 can be positioned at different locations relative to the boundary between the first area 110 and the second area 120. In the embodiment shown in Figure 3, the projection of the knob 200 on the touch screen 100 can be a hollow ring, and the knob 200 has an inner edge 201 and an outer edge 202 arranged in concentric circles. The inner edge 201 surrounds and defines the hollow region 203, that is, the area not covered by the knob 200. When the center of the knob 200 is located on the boundary between the first zone 110 and the second zone 120, the area of ​​the hollow region 203 projected onto the first zone 110 is the same as the area of ​​the hollow region 203 projected onto the second zone 120. When the knob 200 is offset towards the first zone 110, the area of ​​the hollow region 203 projected onto the first zone 110 is larger than the area of ​​the hollow region 203 projected onto the second zone 120. When the knob 200 is offset towards the second zone 120, the area of ​​the hollow region 203 projected onto the first zone 110 is smaller than the area of ​​the hollow region 203 projected onto the second zone 120. The area of ​​the hollow region 203 projected onto the first zone 110 can, for example, be used to display the function parameters adjusted by the knob 200, or to display different images in conjunction with the overall display content design. Additionally, the first zone 110 outside the knob 200 can also display images in conjunction with the shape of the outer edge 202. Depending on various display requirements, the above-mentioned different configurations can be adopted to adjust the area obscured by the knob 200 and the display area of ​​the hollow area 203.

[0025] For the various knob 200 positions described above, different numbers of sub-segments 210 and positions of detectors 220 can be designed to ensure that only one detector 220 is located on the first zone 110 at any given time. For example, when the area of ​​the hollow region 203 projected onto the first zone 110 is the same as the area of ​​the hollow region 203 projected onto the second zone 120, as shown in the embodiment of Figure 3, the knob 200 can have four sub-segments 210. Each rotation segment has two adjacent sub-segments 210 located on the first zone 110, while the other two sub-segments are located on the second zone 120. The two sub-segments 210 that are separated from each other will not be located on the first zone 110 at the same time, so the two detectors 220 can be respectively set in the two separated sub-segments 210. Specifically, as shown on the left side of the animation in Figure 4, the knob 200 has four sub-segments 210A, 210B, 210C, and 210D. Detector 2201 is located in sub-segment 210A and on the first zone 110, while detector 2202 is located in the adjacent sub-segment 210C and on the second zone 120. At this time, the touch screen 100 can detect the position of detector 2201. After rotating 90° along the rotation direction R to the next rotation segment, sub-segment 210A where detector 2201 is located moves to the second zone 120, and sub-segment 210C where detector 2202 is located moves to the first zone 110. At this time, the touch screen 100 can detect the position of detector 2202.

[0026] The above design principles can be adjusted to apply to different numbers of sub-segments 210. For example, the knob 200 can have an even number of sub-segments 210, and the two detectors 220 can be located in two sub-segments 210 that are 180° apart from each other, so that these two sub-segments are not simultaneously located on the first zone 110. The knob 200 can also have an odd number of sub-segments 210. For example, in the embodiment shown in Figure 5, the center of the knob 200 is located on the boundary between the first zone 110 and the second zone 120, and the knob 200 has nine sub-segments 210 (i.e., each segment rotates 40°), and the sub-segments 210 where the detectors 2201 and 2202 are located are separated by three or four sub-segments 210. In certain angular positioning (as shown in Figure 5), the sub-segment 210 where the detector 220 is located will span the first zone 110 and the second zone 120. At this time, one of the detectors (such as detector 2201) is at least partially located on the first zone 110, and the other detector (such as detector 2202) is completely located on the second zone 120.

[0027] When the area of ​​the hollow region 203 projected onto the first zone 110 is smaller than the area of ​​the hollow region 203 projected onto the second zone 120, the knob 200 can adopt a design similar to or different from the above embodiments. For example, in the embodiment shown in Figure 6, the hollow region 203 is completely located on the second zone 120. In this case, the knob 200 can be designed to have four sub-segments 210 and two detectors 2201 and 2202, and two of the sub-segments 210 are at least partially located on the first zone 110. When the sub-segment 210 containing any detector is located on the first zone 110, the detector (such as detector 2201) is at least partially located on the first zone 110, while the sub-segment 210 containing the other detector (such as detector 2202) is completely located on the second zone 120. In one embodiment, at least one-quarter of the outer edge 202 of the knob 200 lies on the projection of the first region 110. When any sub-section 210 containing a sensor is rotated to one of two adjacent positions on the first region 110 (e.g., the upper right and upper left positions in Figure 6), the outer edge 202 corresponding to the middle position of this sub-section 210 lies on the first region 110, such that the sensor (e.g., sensor 2201) located at the middle position of this sub-section 210 is at least partially located on the first region 110. As mentioned above, this design principle can also be adjusted to apply to different numbers of sub-sections 210.

[0028] On the other hand, when the area of ​​the hollow region 203 projected onto the first region 110 is smaller than the area of ​​the hollow region 203 projected onto the second region 120, the knob 200 can adopt a design similar to or different from the above embodiments. For example, in the embodiment shown in FIG7, the hollow region 203 is completely located on the first region 110. In this case, the knob 200 can be designed to have four sub-segments 210 and two detectors 2201 and 2202, and two of the sub-segments 210 are at least partially located on the second region 120. When the sub-segment 210 containing any detector is located on the second region 120, the detector (such as detector 2202) is completely located on the second region 120, while the other detector (such as detector 2201) and its sub-segment 210 are completely located on the first region 110. In one embodiment, at least one-quarter of the outer edge 202 of the knob 200 is located on the projection of the second zone 120. When any sub-segment 210 containing a detector is rotated to one of two adjacent positions on the second zone 120 (e.g., the lower right and lower left positions in Figure 7), the outer edge 202 corresponding to the middle position of this sub-segment 210 is located on the second zone 120, so that the detector (e.g., detector 2202) located at the middle position of the sub-segment 210 is completely located on the second zone 120, while another detector (e.g., detector 2201) is located on the first zone 110 and can be detected.

[0029] The knob 200 may also have a different number of sub-segments 210. For example, in the embodiment shown in FIG8, the knob 200 is biased towards the second zone 120 and has nine sub-segments 210 (i.e., each rotation segment is 40°), wherein the sub-segments 210 where the detectors 2201 and 2202 are located are separated by three or four sub-segments 210. In some rotation states (as shown in FIG8), the sub-segment 210 where the detectors 220 are located will span the first zone 110 and the second zone 120. At this time, one detector (such as detector 2201) is at least partially located on the first zone 110, and the other detector (such as detector 2202) is completely located on the second zone 120.

[0030] With the above configuration, when the knob 200 is positioned at any angle, one sensor 220 is at least partially located on the first area 110, while the other sensor 220 is completely located on the second area 120. The touch screen 100 can be designed so that only the first area 110 can sense the sensor 220, and only the position of one sensor 220 needs to be determined for any angle of the knob 200, thus simplifying the programming for detection.

[0031] For different designs and applications, the present invention may include various positions of the knobs 200, the number of sub-segments 210, and the positions, numbers, or shapes of the detectors 220. For example, the positions of the detectors 220 in the knobs 200 may be equidistant (e.g., the embodiment shown in FIG. 6) or non-equidistant (e.g., the embodiment shown in FIG. 3); the detectors 220 may be the same or different sizes and have shapes such as circles, triangles, or rectangles. For example, the edges of the detectors 220 may be arc-shaped and correspond to the shape of the inner edge 201 and / or outer edge 202 of the knob 200 (as shown in FIG. 3) to provide a relatively large detection area, but are not limited thereto.

[0032] The mechanical structure embodiment of the knob 200 and the auxiliary rotation component will be described next.

[0033] In one embodiment, as shown in Figures 9 and 10, the display device further includes a knob base 300, which overlaps with the touch screen 100 and is located between the touch screen 100 and the knob 200. The knob base 300 may be fixed to the touch screen 100, for example, by adhesive, fitting, or other means, and is rotatably connected to the knob 200, allowing the knob 200 to rotate relative to the knob base 300. The knob base 300 may include an adjacent inner portion 310 and a bottom portion 320, wherein the inner portion 310 corresponds to the inner edge 201 of the knob 200, and the bottom portion 320 is located between the sensor 220 and the touch screen 100. The inner portion 310 may include a rotor 311, which is disposed toward and contacts the knob 200 to assist the knob 200 in rotating relative to the knob base 300. The thickness D of the bottom portion 320 in the direction passing through the touch surface 111 can be designed to not affect the thickness of the touch screen 100 in sensing the detector 220, for example, less than 0.5 mm. Furthermore, the knob 200 may include a conductive cover 230 disposed on the side of the detector 220 away from the touch screen 100, and the conductive cover 230 is connected to the detector 220, for example, by providing a conductive spring 240 between them to maintain good contact between the conductive cover 230 and the detector 220. The conductive cover 230, the conductive spring 240, and the detector 220 may contain conductive materials, such as metals, metal oxides, conductive plastics, etc., to form a current path between the detector 220, the conductive cover 230, and the finger, so that the touch screen 100 can detect the position of the detector 220 when the user touches the conductive cover 230. With the above configuration, the detector 220 does not directly contact the screen, thereby reducing frictional wear on the touch surface 111 and preventing foreign objects such as dust from entering the internal gaps and affecting operation.

[0034] In terms of appearance, as shown in Figure 9, the outer edge 202 of the knob 200 may have a textured or concave structure to increase friction when the user rotates the knob 200. Additionally, as shown in Figures 9 and 10, the knob 200 may include an interior cover 250 located inside the conductive cover 230. This interior cover 250 may have different structures or textures to enhance aesthetics and may also conceal the internal structure of the knob 200 to prevent foreign objects from entering the internal gaps. In different designs, the interior cover 250 may also be a non-rotating component, allowing the conductive cover 230 to rotate relative to the interior cover 250.

[0035] In one embodiment, as shown in Figures 9 to 11, the knob base 300 further includes a positioning member 330 disposed on one side of the knob base 300 away from the touch screen 100, and the knob 200 includes a plurality of positioning mechanisms 260 disposed on one side of the detector 220 away from the touch screen 100, wherein the positioning mechanisms 260 are angularly spaced and can correspond to a plurality of sub-segments 210 (see Figure 3), for example, each sub-segment 210 corresponds to one positioning mechanism 260. When the knob 200 is rotated, the positioning member 330 can engage with one of the positioning mechanisms 260, so that the knob 200 switches between different angular positions. For example, the positioning mechanism 260 can be a recess, with each sub-segment 210 located between two adjacent recesses, or the middle portion of each sub-segment 210 corresponding to a recess; the positioning element 330 can be a spring protruding towards the recess, and the positioning element 330 can be fixed to the inner portion 310 of the knob base 300, for example, by clamping the positioning element 330 between the retaining ring 340 and the inner portion 310 through the retaining ring 340. When the protruding portion of the spring is located between two adjacent recesses, the spring will be compressed and generate a restoring force, causing one of the recesses to move to the position of the protruding portion of the spring. In different designs, the spring can have one or more protruding portions, for example, the spring (i.e., the positioning element 330) shown in Figure 11 has two protruding portions and corresponds to two recesses (i.e., the positioning mechanism 260) that are angularly opposite to each other. As mentioned above, the positioning mechanism 260 and / or the positioning element 330 can serve as a tactile feedback unit to generate tactile feedback such as rebound force or resistance when the knob 200 is rotated. With this configuration, segmented rotation of the knob 200 can be achieved, and tactile feedback can be provided so that the user knows the number of rotation segments operated.

[0036] The above embodiments can be applied to vehicles requiring user operation. As shown in FIG12, one embodiment of the present invention provides a vehicle display system 900, which includes the display device described in the above embodiments. The vehicle display system 900 can be installed on the control console CS in the vehicle, such as the center console next to the driver's seat, and the vehicle display system 900 can be connected to other devices in the vehicle, such as air conditioning system, audio system, entertainment system, etc., and these devices can be controlled by rotating the knob 200. When the user is driving the vehicle, even without directly looking at the vehicle display system 900, the position of the knob 200 can be located by touch and structural differentiation, and the selected function can be quantitatively operated using the knob 200 with rotation segments, so that the user's attention is focused on the direction of vehicle movement, thereby improving the ease of operation and safety of the vehicle control console. In addition, in some embodiments, the image interface of the vehicle display system 900 can be matched with the shape design of the knob 200. For example, when the knob 200 is used to operate the air conditioning system, the screen corresponding to the hollow area 203 (see FIG3) can display the air conditioning temperature. The vehicle display system 900 may also be equipped with a plurality of knobs 200 to correspond to different control functions (not shown). For various interface designs and control requirements, the vehicle display system 900 can employ different knob 200 positions and sensor 220 configurations (see Figures 3 to 8). Through the above configuration, users operating the vehicle can conveniently operate the control panel functions, enhancing safety and user experience.

[0037] The present invention has been described by the above embodiments; however, the above embodiments are for illustrative purposes only and not intended to be limiting. Depending on the design, some elements of one embodiment may be applied to other embodiments, but this is not a limitation. The scope of protection of the present invention shall be determined by the claims. Without departing from the spirit of the present invention, those skilled in the art can make various modifications and refinements without exceeding the scope defined by the appended claims.
