Description

TECHNICAL FIELD

[0001] The present invention relates to a display device and a vehicle display system including the same. In particular, the present invention relates to a display device having a knob partially disposed on a display area and a vehicle display system including the same. BACKGROUND

[0002] Touch screens have become the mainstream interface of many smart display devices, such as mobile phones, vehicle systems, home appliances, and other electronic products. However, compared with traditional physical button devices, touch screens lack the tactile separation and feedback of buttons, and users often need to look at the screen during operation to determine the exact position of the button. If the user operates the touch screen while performing other activities, such as walking or driving, they must divert their gaze to confirm the button position, which reduces the convenience and safety of the smart display device.

[0003] Therefore, some touch display devices still have physical buttons corresponding to functions that are often operated blindly, such as the volume buttons of smart phones and the air conditioning knobs of car consoles. However, compared with the display area of a touch screen, which can have diverse designs and switching displays, the setting positions of these physical buttons are relatively monotonous, and often increase the width of the frame or occupy the display area, reducing the aesthetics and functionality. Therefore, improving the combination design of touch screens and physical buttons / knobs to achieve better functionality and customization requirements is a problem that needs to be solved in the field. SUMMARY

[0004] The present invention provides a display device including a knob disposed across a display area and a non-display area, and multiple detection pieces in the knob are simultaneously detected by a touch screen to achieve the purpose of increasing panel functionality and tactile diversity and simplifying the design of the detection mechanism.

[0005] The present invention also provides a vehicle display system including a display device with a knob disposed across a display area and a non-display area to provide multiple tactile feedback for the user of the vehicle during operation and increase the design variation 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 is located on the extension plane of the touch surface. The knob is at least partially disposed on the first area and partially disposed on the second area, is rotatable relative to the touch screen, and includes multiple sub-sections disposed adjacent in the angular direction; the knob includes at least two detection pieces, the detection pieces are disposed close to the touch screen, and each sub-section includes at most one detection piece. Wherein the touch screen can detect the position of the detection pieces, and only one detection piece is located on the first area at the same time.

[0007] In another aspect, a vehicle display system includes the aforementioned display device, and the vehicle display system is disposed on a console in a vehicle. BRIEF DESCRIPTION OF DRAWINGS

[0047] like Figure 1 and Figure 2 As shown, 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 the second area 120 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 containing the touch surface 111. Figure 3As shown, the knob 200 further comprises a plurality of sub-sections 210 arranged adjacently in the angular direction. The rotation of the knob 200 has a segmentation corresponding to the sub-sections 210, for example, when the sub-sections 210 are four, the knob 200 can be rotated by one quarter of a circle for each segment (i.e. the minimum rotation angle is 90°). In other words, the sub-sections 210 are switched in different angular positions by rotating the knob 200 together, and after rotating a segment, the projection position of the sub-sections 210 on the touch screen 100 coincides with the position of the adjacent sub-section 210 before rotation. Among them, the sub-sections 210 are virtual or physical areas defined for the convenience of design and description, and the 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 feedback generating parts (not shown) arranged adjacently in the angular direction, each sub-section 210 can be located between adjacent tactile feedback generating parts, but not limited to this; when the knob 200 is rotated, the tactile feedback generating parts are rotated together to the adjacent angular position and provide tactile feedback, such as elastic force or resistance feeling, etc.

[0048] In addition, the knob 200 includes at least two detection members 220, which can be arranged close to the touch screen 100, and each sub-section 210 includes at most one detection member 220, that is, each sub-section 210 includes a complete detection member 220 or no detection member 220, and the area of each detection member 220 is smaller than the area of the sub-section 210 where it is located. Among them, the touch screen 100 can detect the position of these detection members 220, and at any angular position, only one detection member 220 is located on the first area 110. In some embodiments, the first area 110 can include a plurality of sensing units, when the detection member 220 is located on the projection of one or more sensing units, the sensing unit will generate an electrical signal, which is used to determine the position of the detection member 220 and correspond to one of the rotation segments. For example, in an embodiment, the area and position of the sensing unit can correspond to the projection of the sub-section 210 on the first area, so that at any angular position of the knob 200, there is a sub-section 210 including a detection member 220 located on one of the sensing units; in another aspect, the range of the sub-section 210 can be defined by the area and position of the sensing unit. In another embodiment, the sub-section including the detection member 220 can cover a plurality of sensing units, and the detection member 220 is located on one or more sensing units, but not limited to this.

[0049] 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.

[0050] like Figure 3 In the illustrated embodiment, the knob 200 includes two sensing elements 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 region 110 and the second region 120. Figure 3 In the illustrated embodiment, the projection of the knob 200 onto the touchscreen 100 can be a hollow annular shape, 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, i.e., the area not covered by the knob 200. When the center of the knob 200 is located on the boundary between the first region 110 and the second region 120, the area of ​​the hollow region 203 on the projection of the first region 110 is the same as the area of ​​the hollow region 203 on the projection of the second region 120. When the knob 200 is offset towards the first region 110, the area of ​​the hollow region 203 on the projection of the first region 110 is larger than the area of ​​the hollow region 203 on the projection of the second region 120. When the knob 200 is offset towards the second region 120, the area of ​​the hollow region 203 on the projection of the first region 110 is smaller than the area of ​​the hollow region 203 on the projection of the second region 120. The area of ​​the hollow region 203 projected onto the first zone 110 can be used, for example, to display the function parameters adjusted by the knob 200, or to display different images in accordance 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 region 203.

[0051] For various knob 200 positions, different numbers of sub-sections 210 and detection members 220 positions can be designed to achieve the condition that only one detection member 220 is located on the first area 110 at the same time. For example, when the area of the hollow region 203 projected on the first area 110 is the same as the area of the hollow region 203 projected on the second area 120, such as Figure 3 In the embodiment shown in FIG. 2A, the knob 200 can have four sub-sections 210, two adjacent sub-sections 210 of each rotation section are located on the first area 110, while the other two sub-sections are located on the second area 120, wherein the two sub-sections 210 that are not adjacent to each other will not be located on the first area 110 at the same time, and thus two detection members 220 can be arranged in the two sub-sections 210 that are not adjacent to each other. Specifically, as shown on the left side of the actuation diagram in FIG. 2A, the knob 200 has four sub-sections 210A, 210B, 210C, and 210D, wherein the detection member 2201 is located in the sub-section 210A and on the first area 110, and the detection member 2202 is located in the sub-section 210C and on the second area 120, at this time the touch screen 100 can detect the position of the detection member 2201; after rotating 90° in the rotation direction R to the next rotation section, the sub-section 210A where the detection member 2201 is located moves to the second area 120, and the sub-section 210C where the detection member 2202 is located moves to the first area 110, at this time the touch screen 100 can detect the position of the detection member 2202. Figure 4

[0052] The above design principles can be adjusted to be applicable to different numbers of sub-sections 210, for example, the knob 200 can have an even number of sub-sections 210, and two detection members 220 can be arranged in two sub-sections 210 that are 180° apart from each other, so that the two sub-sections will not be located on the first area 110 at the same time. The knob 200 can also have an odd number of sub-sections 210, for example Figure 5 In the embodiment shown in FIG. 2B, the center of the knob 200 is located on the boundary between the first area 110 and the second area 120, and the knob 200 has nine sub-sections 210 (i.e., 40° per rotation section), and the sub-sections 210 where the detection member 2201 and the detection member 2202 are located are separated by three or four sub-sections 210. In some angular positions (such as the position shown in FIG. 2B), the sub-section 210 where the detection member 220 is located will cross the first area 110 and the second area 120, at this time one of the detection members (such as the detection member 2201) is at least partially located on the first area 110, and the other detection member (such as the detection member 2202) is completely located on the second area 120. Figure 5

[0053] When the area of the hollow region 203 projected on the first area 110 is smaller than the area of the hollow region 203 projected on the second area 120, the knob 200 can adopt a similar or different design to the above-mentioned embodiments. For example Figure 6 ​​In the embodiment shown, the hollow region 203 is entirely located on the second zone 120, in which case the knob 200 can be designed to have four sub-sections 210 and two detection members 2201, 2202, and two of the sub-sections 210 are at least partially located on the first zone 110. When any of the sub-sections 210 in which a detection member is located is rotated to one of the two adjacent positions on the first zone 110 (e.g., the right upper and left upper positions in Figure 6 ), the outer edge 202 corresponding to the middle position of the sub-section 210 is located on the first zone 110, so that the detection member (e.g., the detection member 2201) disposed at the middle position of the sub-section 210 is at least partially located on the first zone 110. As described above, this design principle can also be adjusted for different numbers of sub-sections 210.

[0054] On the other hand, when the area of the hollow region 203 located on the projection of the first zone 110 is smaller than the area of the hollow region 203 located on the projection of the second zone 120, the knob 200 can be designed similarly or differently from the above embodiment. For example, as shown in the embodiment, Figure 7 the hollow region 203 is entirely located on the first zone 110, in which case the knob 200 can be designed to have four sub-sections 210 and two detection members 2201, 2202, and two of the sub-sections 210 are at least partially located on the second zone 120. When any of the sub-sections 210 in which a detection member is located is rotated to one of the two adjacent positions on the second zone 120 (e.g., the right lower and left lower positions in Figure 7 ), the outer edge 202 corresponding to the middle position of the sub-section 210 is located on the second zone 120, so that the detection member (e.g., the detection member 2202) disposed at the middle position of the sub-section 210 is entirely located on the second zone 120, and the other detection member (e.g., the detection member 2201) is located on the first zone 110 and can be detected.

[0055] The knob 200 can also have different numbers of sub-sections 210, for example, Figure 8In the illustrated embodiment, the knob 200 is disposed with the second region 120 and has nine sub-segments 210 (i.e., each rotation segment is 40°), wherein the sub-segments 210 where the detection pieces 2201 and 2202 are located are separated by three or four sub-segments 210. In certain rotation states (e.g., the illustrated position), the sub-segment 210 where the detection pieces 220 are located will span the first region 110 and the second region 120, at which time one of the detection pieces (e.g., the detection piece 2201) is at least partially located on the first region 110, and the other detection piece (e.g., the detection piece 2202) is completely located on the second region 120. Figure 8 In the illustrated position, the sub-segment 210 where the detection pieces 220 are located will span the first region 110 and the second region 120, at which time one of the detection pieces (e.g., the detection piece 2201) is at least partially located on the first region 110, and the other detection piece (e.g., the detection piece 2202) is completely located on the second region 120.

[0056] By the above configuration, when the knob 200 is in any angular position, there is exactly one detection piece 220 at least partially located on the first region 110, and the other detection piece 220 is completely located on the second region 120. The touch screen 100 can be designed such that only the first region 110 can sense the detection pieces 220, and thus only one detection piece 220 needs to be judged in position corresponding to any angular position of the knob 200, so as to simplify the program design for detection.

[0057] For different designs and applications, the present application can include various positions of the knob 200, the number of sub-segments 210, and the position, number, or shape of the detection pieces 220. For example, the positions of the detection pieces 220 in the knob 200 can be equidistant (e.g., the illustrated embodiment) or non-equidistant (e.g., the illustrated embodiment); the detection pieces 220 can be the same or different sizes, and have shapes such as circular, triangular, or rectangular, e.g., the edges of the detection pieces 220 can be circular arcs and correspond to the shape of the inner edge 201 and / or the outer edge 202 of the knob 200 (e.g., the illustrated embodiment), so as to provide a relatively large detection area, but not limited thereto. Figure 6 Figure 3 For example, the positions of the detection pieces 220 in the knob 200 can be equidistant (e.g., the illustrated embodiment) or non-equidistant (e.g., the illustrated embodiment); the detection pieces 220 can be the same or different sizes, and have shapes such as circular, triangular, or rectangular, e.g., the edges of the detection pieces 220 can be circular arcs and correspond to the shape of the inner edge 201 and / or the outer edge 202 of the knob 200 (e.g., the illustrated embodiment), so as to provide a relatively large detection area, but not limited thereto. Figure 3

[0058] Next, the mechanical structure embodiment of the knob 200 and the auxiliary rotation assembly will be described.

[0059] In an embodiment, as shown in Figure 9 and Figure 10 ​​As shown, the display device further comprises a knob base 300 which is overlapped with the touch screen 100 and located between the touch screen 100 and the knob 200. The knob base 300 can be fixed on the touch screen 100 by, for example, adhesion, embedding or other means, and rotatably connected with the knob 200 so that the knob 200 can rotate relative to the knob base 300. The knob base 300 can comprise an adjacent inner portion 310 corresponding to the position of the inner edge 201 of the knob 200 and a bottom portion 320 located between the detecting member 220 and the touch screen 100. The inner portion 310 can comprise a rotor 311 which is arranged towards the knob 200 and contacts the knob 200 to assist the rotation of the knob 200 relative to the knob base 300. The thickness D of the bottom portion 320 in the direction through the touch surface 111 can be designed to not affect the thickness of the detecting member 220 sensed by the touch screen 100, for example, less than 0.5 mm. In addition, the knob 200 can comprise a conductive cover 230 arranged on the side of the detecting member 220 away from the touch screen 100, and the conductive cover 230 is connected with the detecting member 220, for example, a conductive spring 240 is arranged between the two to maintain good contact between the conductive cover 230 and the detecting member 220. The conductive cover 230, the conductive spring 240 and the detecting member 220 can comprise conductive materials, such as metals, metal oxides, conductive plastics, etc., to form a current path between the detecting member 220, the conductive cover 230 and the finger, so that the touch screen 100 can detect the position of the detecting member 220 when the user touches the conductive cover 230. By the above arrangement, the detecting member 220 does not directly contact the screen to reduce the friction wear of the touch surface 111 and avoid foreign matter such as dust entering the internal gap to affect the operation.

[0060] In terms of appearance, as shown in Figure 9 The outer edge 202 of the knob 200 can have a concave-convex structure or texture to increase friction when the user rotates the knob 200. In addition, as shown in Figure 9 and Figure 10 The knob 200 can comprise an interior cover 250 inside the conductive cover 230, which can have different structures or textures to increase the aesthetic appearance, and can also cover the internal structure of the knob 200 to avoid foreign matter entering the internal gap. In different designs, the interior cover 250 can also be a non-rotating component, so that the conductive cover 230 rotates relative to the interior cover 250.

[0061] In an embodiment, as shown in Figures 9 to 11 The knob base 300 further comprises a positioning member 330 arranged on the side of the knob base 300 away from the touch screen 100, and the knob 200 comprises a plurality of positioning mechanisms 260 arranged on the side of the detecting member 220 away from the touch screen 100, wherein the positioning mechanisms 260 are arranged at an angle and can correspond to the plurality of sub-sections 210 (see Figure 3), for example, each sub-section 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 to switch the knob 200 between different angular positions. For example, the positioning mechanisms 260 can be recesses, and each sub-section 210 is located between two adjacent recesses, or the middle portion of each sub-section 210 corresponds to one recess; the positioning member 330 can be a spring piece protruding towards the recesses, and the positioning member 330 can be fixed on the inner portion 310 of the knob base 300, for example, by clamping the positioning member 330 between the clamping ring 340 and the inner portion 310. When the protruding portion of the spring piece is located between two adjacent recesses, the spring piece is compressed to generate a restoring force to move one of the recesses to the position matching the protruding portion of the spring piece. In different designs, the spring piece can have one or more protruding portions, for example Figure 11 The spring piece (i.e., the positioning member 330) shown has two protruding portions and corresponds to two recesses (i.e., the positioning mechanisms 260) disposed opposite in angle, respectively. As described above, the positioning mechanisms 260 and / or the positioning member 330 can serve as the tactile sensation generating portion to generate a restoring force or a resistance feeling or other tactile feedback when the knob 200 is rotated. By this arrangement, the segmented rotation of the knob 200 can be achieved, and the tactile feedback can be provided to inform the user of the number of rotated segments.

[0062] The above embodiments can be applied to vehicles that need to be controlled by the user. As shown in Figure 12 An embodiment of the present application provides a vehicle display system 900 including the display device described in the above embodiments. The vehicle display system 900 can be arranged on a console CS in the vehicle, for example, a center console beside the driver's seat, and the vehicle display system 900 can be connected to other devices in the vehicle, for example, an air conditioning system, a sound system, an entertainment system, etc., and control these devices by rotating the knob 200. When the user drives the vehicle, the position of the knob 200 can be located by tactile sensation and structural segmentation even without looking at the vehicle display system 900, and the selected function can be quantitatively operated by using the knob 200 with segmented rotation, so that the user's attention is focused on the direction in which the vehicle is moving, to improve the convenience and safety of the operation of the vehicle console. In addition, in some embodiments, the image interface of the vehicle display system 900 can be matched with the design of the knob 200, for example, when the knob 200 is used to operate the air conditioning system, the hollow area 203 (see Figure 3 ) corresponds to a screen that displays the air conditioning temperature. Multiple knobs 200 can also be provided in the vehicle display system 900 to correspond to different control functions (not shown in the figure). For various interface designs and control requirements, the vehicle display system 900 can use different configurations of the position of the knob 200 and the detection member 220 (see Figures 3 to 8). By the above configuration, the user who manipulates the vehicle can conveniently operate the console function, and safety and user experience are improved.

[0063] The present application has been described by the above embodiments, however, the above embodiments are only for illustrative purposes and not for limiting. According to different designs, some elements in one embodiment can be applied to other embodiments, but not limited thereto. The protection scope of the present application is subject to the scope defined by the appended patent claims, and those skilled in the art can make various modifications and decorations without departing from the spirit of the present application, and without exceeding the scope of the present application defined by the appended patent claims.
