Description

Technical Field

[0001] This application relates to the field of automotive technology, and in particular to a display module, an image generation unit, a human-machine interaction system for automotive head-up display, and an automobile. Background Technology

[0002] A head-up display (HUD) is an advanced driver assistance system, also known as a head-up imaging system. In the continuous development and evolution of HUD technology, the pursuit of better imaging effects and richer information presentation has always been one of the core goals. An automotive HUD imaging system includes an image generation unit and a windshield. When the HUD is working, the light generated by the image generation unit shines onto the windshield and is reflected back to the front of the windshield to form a distant virtual image. In related technologies, light from outside the HUD imaging system can easily penetrate the display module of the image generation unit. The energy generated by this penetrating light can burn the components within the display module, causing damage and affecting the normal operation of the image generation unit. Summary of the Invention

[0003] Therefore, it is necessary to address the problem that external light from the current automotive head-up display imaging system can easily shine into the display module of the image generation unit, and to propose a display module, an image generation unit, a human-computer interaction system for automotive head-up display, and an automotive vehicle.

[0004] A display module, comprising:

[0005] Display screen;

[0006] A light filtering component is located, at least partially, on the light-emitting side of the display screen;

[0007] The light filtering component includes a first color resist layer and a second color resist layer of different colors, which are rotatably arranged relative to the display screen. When the display module is in the first state, one of the first color resist layer and the second color resist layer overlaps with the display screen along the thickness direction of the display screen.

[0008] In this embodiment, the display module has a light filtering component at least partially disposed on the light-emitting side of the display screen. The first and second color resist layers of the light filtering component are rotatable relative to the display screen. This allows one of the first and second color resist layers to rotate relative to the display screen and overlap with it along the thickness direction when external light shines on it. Since the first and second color resist layers have a light filtering function, when one of them overlaps with the display screen along its thickness direction, at least a portion of the light shining on the display screen can be filtered out by the first and second color resist layers. Furthermore, because the first and second color resist layers are different colors, they can filter different types of light shining on the display screen separately. In the above process, by using a first color resist layer and a second color resist layer to filter the light incident on the display screen, it is more difficult for light from outside the display screen to enter the display screen, thereby reducing the amount of external light incident on the display screen, reducing the radiation generated by the light incident on the display screen, reducing the risk of the components inside the display screen being burned by external light, avoiding damage to the display screen due to excessive light incident on the display screen, and ensuring the normal operation of the display screen.

[0009] In summary, the display module in this embodiment, through the above-mentioned settings, makes it more difficult for light from outside the display screen to enter the display screen, thereby reducing the risk of damage to the display module.

[0010] This application also proposes an image generation unit, which includes the aforementioned display module, and

[0011] A housing surrounds and forms a receiving cavity. A light-transmitting hole is provided on the shell wall of the housing, and the light-transmitting hole communicates with the receiving cavity. The display module is located inside the receiving cavity, and the light filtering component of the display module is located between the display screen of the display module and the light-transmitting hole.

[0012] A reflector assembly is located within the receiving cavity; the reflector assembly is used to reflect the light emitted by the display module into the light-transmitting hole.

[0013] In this embodiment, the image generation unit, by placing the display module within the housing cavity, isolates the display module from the external environment, reducing the corrosive effects of dust or moisture and extending its lifespan. By providing a light-transmitting hole in the housing wall and placing the reflector assembly within the housing cavity, light emitted from the display module's screen, after being filtered by the light filter assembly and reflected by the reflector assembly, passes through the light-transmitting hole and exits the housing cavity. It is important to emphasize that by using a reflector assembly to reflect the light emitted from the display module into the light-transmitting hole, the placement requirements for the light-transmitting hole are reduced, eliminating the need for it to be positioned in the light-emitting direction of the display module. Furthermore, when light from outside the image generation unit passes through the light-transmitting hole to the reflector assembly and is reflected by the reflector assembly towards the display module, the display module's filtering assembly also filters this light, reducing the amount of light entering the display module and lowering the risk of damage.

[0014] In summary, the image generation unit in this embodiment, through the above-described settings, can reduce the risk of damage to the display module and extend its service life.

[0015] This application also proposes a human-computer interaction system for a car head-up display, including the aforementioned image generation unit, and

[0016] A windshield, located at the light-transmitting hole of the image generation unit, on the side opposite to the display module of the image generation unit.

[0017] This application also proposes a car including the aforementioned head-up display human-computer interaction system.

[0018] In this embodiment, the human-computer interaction system of the car head-up display and the car, the light emitted by the display module's screen is filtered by the light filtering component, and after being shot towards the reflector component, it can be reflected by the reflector component, and under the reflection of the reflector component, it passes through the light transmission hole, leaves the housing cavity through the light transmission hole, shoots out of the housing, shoots towards the windshield, and is then reflected by the windshield to the side of the windshield away from the image generation unit to form a distant virtual image, which provides driving assistance to the car driver.

[0019] In addition, when light from outside the image generation unit passes through the light-transmitting hole to the reflector assembly and is emitted by the reflector assembly to the display module, the filtering component of the display module will also filter the light to reduce the amount of light entering the display module and reduce the risk of damage to the display module.

[0020] In summary, the human-computer interaction system of the car head-up display in this embodiment, along with the car itself, can assist the driver and reduce the amount of light entering the display module. Attached Figure Description

[0036] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0037] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0038] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0040] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0041] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0042] Please see Figure 1 , Figure 2 as well as Figure 6 and Figure 8 , Figure 1 This is a schematic diagram of the structure of a human-computer interaction system for a car head-up display according to an embodiment of this application. Figure 2 It shows Figure 1The diagram shows a structural schematic of a display module 100. One embodiment of this application provides a display module 100, including a display screen 110 and a light filtering assembly 120. The light filtering assembly 120 is at least partially located on the light-emitting side of the display screen 110. The light filtering assembly 120 includes a first color resist layer 121 and a second color resist layer 122 of different colors, which are rotatably disposed relative to the display screen 110. When the display module 100 is in a first state, one of the first color resist layer 121 and the second color resist layer 122 overlaps with the display screen 110 along the thickness direction V1 of the display screen 110. It should be noted that the first state refers to the state of the display module 100 when the light filtering assembly 120 filters the light incident on the display screen 110.

[0043] In this embodiment, the display module 100 has a light filtering component 120 at least partially disposed on the light-emitting side of the display screen 110. The first color resist layer 121 and the second color resist layer 122 of the light filtering component 120 are rotatable relative to the display screen 110. This allows one of the first color resist layer 121 and the second color resist layer 122 to rotate relative to the display screen 110 and overlap with the display screen 110 along the thickness direction V1 when external light is incident on the display screen 110. Since the first color resist layer 121 and the second color resist layer 122 have a light filtering function, when one of the first color resist layer 121 and the second color resist layer 122 overlaps with the display screen 110 along the thickness direction V1, at least a portion of the light incident on the display screen 110 can be filtered out by the first color resist layer 121 and the second color resist layer 122. Furthermore, since the first color resist layer 121 and the second color resist layer 122 are of different colors, they can respectively filter different types of light rays incident on the display screen 110. In the above process, by using the first color resist layer 121 and the second color resist layer 122 to filter the light incident on the display screen 110, it becomes more difficult for external light to enter the display screen 110, thereby reducing the amount of external light entering the display screen 110, reducing the radiation generated by the light entering the display screen 110, lowering the risk of the components inside the display screen 110 being burned by external light, and preventing damage to the display screen 110 due to excessive light entering the display screen 110, thus ensuring the normal operation of the display screen 110.

[0044] In summary, the display module 100 in this embodiment, through the above-mentioned settings, makes it more difficult for light from outside the display screen 110 to enter the display screen 110, thereby reducing the risk of damage to the display module 100.

[0045] Optionally, when the display module 100 is in the first state, one of the first color resist layer 121 and the second color resist layer 122 overlaps with the display screen 110 along the thickness direction V1 of the display screen 110. In this way, when the display module 100 is in the first state, one of the first color resist layer 121 and the second color resist layer 122 can filter out more light incident on the display screen 110.

[0046] Optionally, when the display module 100 is in the second state, the first color resist layer 121 and the second color resist layer 122 are removed from the light-emitting side of the display screen 110. At this time, the first color resist layer 121 and the second color resist layer 122 of the light filtering assembly 120 will not filter the light incident on the display screen 110. In this way, the display screen 110 can switch between the first state and the second state as needed.

[0047] Please see Figure 1 and Figure 2 In some embodiments, the display screen 110 includes a first light-emitting device 111 and a second light-emitting device 112 with different light-emitting colors. The light-emitting color of the first light-emitting device 111 is the same as the color of the first color resist layer 121, and the light-emitting color of the second light-emitting device 112 is the same as the color of the second color resist layer 122. The rotation axis V2 of the light filtering assembly 120 intersects the thickness direction V1 of the display screen 110. When the display module 100 is in the first state, the light filtering assembly 120 rotates relative to the display screen 110 so that one of the first color resist layer 121 and the second color resist layer 122 overlaps with the display screen 110 along the thickness direction V1 of the display screen 110.

[0048] In this embodiment, the display module 100 sets the color of the first light-emitting device 111 to be the same as the color of the first color resist layer 121. This allows the light filtering component 120 to rotate relative to the display screen 110 when the first light-emitting device 111 emits light, causing the first color resist layer 121 to overlap with the display screen 110 along the thickness direction V1 of the display screen 110. This allows the first color resist layer 121 to filter out the light emitted by other light-emitting devices besides the first light-emitting device 111.

[0049] Similarly, by setting the color of the second light-emitting device 112 to be the same as the color of the second color resist layer 122, when the second light-emitting device 112 of the display screen 110 emits light, it can drive the light filtering component 120 to rotate relative to the display screen 110, so that the second color resist layer 122 overlaps with the display screen 110 along the thickness direction V1 of the display screen 110, thereby relying on the second color resist layer 122 to filter out the light emitted by other light-emitting devices other than the first light-emitting device 111.

[0050] It should be noted that the display screen 110 includes either an OLED (Organic Light-Emitting Diode) screen or an MLED (Micro Light-Emitting Diode) screen.

[0051] Optionally, the first light-emitting device 111 includes multiple devices, and the multiple first light-emitting devices 111 are arranged at intervals.

[0052] Optionally, the second light-emitting device 112 includes a plurality of second light-emitting devices 112, which are arranged at intervals.

[0053] Optionally, please refer to Figure 4 The light filtering assembly 120 also includes a third color resist layer 123. The colors of the first color resist layer 121 and the second color resist layer 122 are different from the color of the third color resist layer 123. The third color resist layer 123 is rotatably configured relative to the display screen 110. When the display module 100 is in the first state, one of the first color resist layer 121, the second color resist layer 122, and the third color resist layer 123 overlaps with the display screen 110 along the thickness direction V1 of the display screen 110.

[0054] Optionally, please refer to Figure 3 The display screen 110 includes a third light-emitting device 113. The light-emitting colors of the first light-emitting device 111 and the second light-emitting device 112 are different from the light-emitting color of the third light-emitting device 113. The light-emitting color of the third light-emitting device 113 is the same as the color of the third color resist layer 123.

[0055] Optionally, the third light-emitting device 113 may include multiple devices.

[0056] Please see Figure 3 In other embodiments, the display screen 110 is configured as an LCD (Liquid Crystal Display) screen. The backlight 130 of the display screen 110 is located on the side of the display screen 110 away from the light filtering assembly 120. A first light-emitting device 111 and a second light-emitting device 112 are provided on the side of the backlight 130 near the display screen 110. The light emission color of the first light-emitting device 111 is the same as the color of the first color resist layer 121, and the light emission color of the second light-emitting device 112 is the same as the color of the second color resist layer 122. The rotation axis V2 of the light filtering assembly 120 intersects the thickness direction V1 of the display screen 110. When the display module 100 is in the first state, the light filtering assembly 120 rotates relative to the display screen 110 so that one of the first color resist layer 121 and the second color resist layer 122 overlaps with the display screen 110 along the thickness direction V1 of the display screen 110.

[0057] Optionally, please refer to Figure 5A third light-emitting device 113 is provided on the side of the backlight 130 near the display screen 110. The light-emitting color of the first light-emitting device 111 and the light-emitting color of the second light-emitting device 112 are different from the light-emitting color of the third light-emitting device 113. The light-emitting color of the third light-emitting device 113 is the same as the color of the third color resist layer 123.

[0058] Please see Figure 1 and Figure 2 In some embodiments, the first light-emitting device 111 and the second light-emitting device 112 emit light sequentially. When the first light-emitting device 111 emits light, the first color resist layer 121 overlaps with the display screen 110 along the thickness direction V1 of the display screen 110; when the second light-emitting device 112 emits light, the second color resist layer 122 overlaps with the display screen 110 along the thickness direction V1 of the display screen 110.

[0059] In this embodiment, the display module 100 is configured such that when the first light-emitting device 111 emits light, the first color resist layer 121 overlaps with the display screen 110 along the thickness direction V1 of the display screen 110. This allows the first color resist layer 121 to filter the light incident on the display screen 110 during the process of the first light-emitting device 111 emitting light. Specifically, the first color resist layer 121 filters light that has a different color from the light emitted by the first light-emitting device 111.

[0060] Similarly, when the second light-emitting device 112 emits light, the second color resist layer 122 overlaps with the display screen 110 along the thickness direction V1 of the display screen 110, so that the second color resist layer 122 can filter the light incident on the display screen 110 during the process of the second light-emitting device 112 emitting light. Specifically, the second color resist layer 122 filters light that has a different color from the light emitted by the second light-emitting device 112.

[0061] Optionally, please refer to Figure 4 and Figure 5 The first light-emitting device 111, the second light-emitting device 112, and the third light-emitting device 113 emit light in sequence. When the third light-emitting device 113 emits light, the third color resist layer 123 overlaps with the display screen 110 along the thickness direction V1 of the display screen 110.

[0062] Optionally, please refer to Figure 4 and Figure 5 The first light-emitting device 111 emits red light, the second light-emitting device 112 emits green light, and the third light-emitting device 113 emits blue light. In this way, the first light-emitting device 111, the second light-emitting device 112, and the third light-emitting device 113 can synthesize white light by emitting light in sequence.

[0063] Please see Figures 1 to 3In some embodiments, the light filtering assembly 120 includes a light-transmitting element 124, a portion of which is located on the light-emitting side of the display screen 110. The light-transmitting element 124 is rotatably disposed relative to the display screen 110. A first color resist layer 121 and a second color resist layer 122 are arranged at intervals on the peripheral wall of the light-transmitting element 124 along the rotation direction of the light filtering assembly 120.

[0064] In this embodiment, the display module 100 is rotatably configured relative to the display screen 110. The first color resist layer 121 and the second color resist layer 122 are arranged at intervals on the peripheral wall of the light-transmitting element 124 along the rotation direction of the light filtering assembly 120. Thus, during the rotation of the light-transmitting element 124, one of the first color resist layer 121 and the second color resist layer 122 can move to the light-emitting side of the display screen 110 under the drive of the light-transmitting element 124 and overlap with the display screen 110 along the thickness direction V1 of the display screen 110.

[0065] Optionally, the rotation axis of the light-transmitting element 124 coincides with the rotation axis V2 of the light filtering assembly 120.

[0066] Optionally, please refer to 4 and Figure 5 The third color resist layer 123 is disposed on the peripheral wall of the light filtering assembly 120, and along the rotation direction of the light filtering assembly 120, the third color resist layer 123 is located between the first color resist layer 121 and the second color resist layer 122.

[0067] Please see Figure 2 and Figure 3 In some embodiments, the peripheral wall of the light-transmitting element 124 includes a first mounting surface 124-1, a second mounting surface 124-2, a first isolation surface 124-4, and a second isolation surface 124-5. Along the rotation direction of the light filtering assembly 120, the first mounting surface 124-1, the first isolation surface 124-4, the second mounting surface 124-2, and the second isolation surface 124-5 are arranged alternately. A first color resist layer 121 is disposed on the first mounting surface 124-1, and a second color resist layer 122 is disposed on the second mounting surface 124-2. When the display module 100 is in the first state, the first mounting surface 124-1 and the first isolation surface 124-4 rotate to the light-emitting side of the display screen 110 and are positioned opposite each other along the thickness direction V1 of the display screen 110; the second mounting surface 124-2 and the second isolation surface 124-5 rotate to the light-emitting side of the display screen 110 and are positioned opposite each other along the thickness direction V1 of the display screen 110.

[0068] In this embodiment, when the first light-emitting device 111 emits light, the light-transmitting element 124 rotates relative to the display screen 110 until the first mounting surface 124-1 and the first insulating surface 124-4 are positioned relative to the light-emitting side of the display screen 110 and are arranged opposite each other along the thickness direction V1 of the display screen 110. Thus, the light emitted by the first light-emitting device 111 can pass through the first color resist layer 121, pass through the first mounting surface 124-1, enter the light-transmitting element 124, and then exit from the first insulating surface 124-4. The first color resist layer 121 can partially filter the light emitted from the first mounting surface 124-1 onto the display screen 110, filtering out light with a color different from that emitted by the first light-emitting device 111.

[0069] Similarly, when the second light-emitting device 112 emits light, the light-transmitting element 124 rotates relative to the display screen 110 until the second mounting surface 124-2 and the second insulating surface 124-5 are positioned on the light-emitting side of the display screen 110 and are arranged opposite each other along the thickness direction V1 of the display screen 110. In this way, the light emitted by the second light-emitting device 112 can pass through the second color resist layer 122, pass through the second mounting surface 124-2 and enter the light-transmitting element 124, and then exit the light-transmitting element 124 from the second insulating surface 124-5. The second color resist layer 122 can partially filter the light emitted from the second mounting surface 124-2 onto the display screen 110, filtering out light with a color different from that emitted by the second light-emitting device 112.

[0070] Please see Figure 4 and Figure 5 In other embodiments, the peripheral wall of the light-transmitting element 124 includes a first mounting surface 124-1, a second mounting surface 124-2, a first insulating surface 124-4, a second insulating surface 124-5, a third mounting surface 124-3, and a third insulating surface 124-6. Along the rotation direction of the light filtering assembly 120, the first mounting surface 124-1, the third insulating surface 124-6, the second mounting surface 124-2, the first insulating surface 124-4, the third mounting surface 124-3, and the second insulating surface 124-5 are arranged alternately. A first color resist layer 121 is disposed on the first mounting surface 124-1, a second color resist layer 122 is disposed on the second mounting surface 124-2, and a third color resist layer 123 is disposed on the third mounting surface 124-3. When the display module 100 is in the first state, the first mounting surface 124-1 and the first isolation surface 124-4 are rotated to the light-emitting side of the display screen 110 and are arranged opposite each other along the thickness direction V1 of the display screen 110; the second mounting surface 124-2 and the second isolation surface 124-5 are rotated to the light-emitting side of the display screen 110 and are arranged opposite each other along the thickness direction V1 of the display screen 110; the third mounting surface 124-3 and the third isolation surface 124-6 are rotated to the light-emitting side of the display screen 110 and are arranged opposite each other along the thickness direction V1 of the display screen 110.

[0071] Please see Figure 2 and Figure 3 In some embodiments, the rotation axis V2 of the light filtering assembly 120 passes through the center of the light-transmitting element 124, and the first mounting surface 124-1 and the first isolation surface 124-4, as well as the second mounting surface 124-2 and the second isolation surface 124-5, are symmetrical about the rotation axis V2 of the light filtering assembly 120.

[0072] In this embodiment, the display module 100 is configured such that the first mounting surface 124-1 and the first isolation surface 124-4 are symmetrical about the rotation axis V2 of the light filtering component 120, ensuring that the distances from the first mounting surface 124-1 and the first isolation surface 124-4 to the rotation axis V2 of the light filtering component 120 are equal. Similarly, by configuring the second mounting surface 124-2 and the second isolation surface 124-5 to be symmetrical about the rotation axis V2 of the light filtering component 120, the distances from the second mounting surface 124-2 and the second isolation surface 124-5 to the rotation axis V2 of the light filtering component 120 are also equal.

[0073] Optionally, the light-transmitting element 124 is constructed as a regular quadrilateral columnar transparent body.

[0074] Please see Figure 4 and Figure 5 Optionally, the third mounting surface 124-3 and the third isolation surface 124-6 are symmetrical about the rotation axis V2 of the light filter assembly 120, respectively.

[0075] Optionally, the light-transmitting element 124 is constructed as a regular hexagonal columnar transparent body.

[0076] Please see Figure 2 and Figure 3 In some embodiments, the display module 100 includes a first driving member 140, which is located on one side of the light-transmitting member 124 along the extension direction of the rotation axis V2 of the light filtering assembly 120. The output end of the first driving member 140 is connected to the light-transmitting member 124. The first driving member 140 is used to drive the light-transmitting member 124 to rotate so that when the first light-emitting device 111 emits light, the first color resist layer 121 rotates to the light-emitting side of the display screen 110, and when the second light-emitting device 112 emits light, the second color resist layer 122 rotates to the light-emitting side of the display screen 110.

[0077] In this embodiment, the display module 100 connects the output end of the first driving member 140 to the light-transmitting member 124, so that the light-transmitting member 124 can automatically rotate relative to the display screen 110 under the drive of the first driving member 140, which can better save manpower.

[0078] Optionally, please refer to Figure 4 and Figure 5The first driving member 140 is used to drive the light-transmitting member 124 to rotate so that when the third light-emitting device 113 emits light, the third color resist layer 123 rotates to the light-emitting side of the display screen 110.

[0079] Optionally, the first driving component 140 includes, but is not limited to, common rotary motion driving devices such as pneumatic motors, servo motors, and hydraulic pumps.

[0080] Please see Figures 6 to 8 In some embodiments, the first color resist layer 121 includes a first flexible color resist layer (not shown in the figure), and the second color resist layer 122 includes a second flexible color resist layer (not shown in the figure). The first color resist layer 121 and the second color resist layer 122 are disposed around the outside of the display screen 110 and are arranged along the rotation direction of the light filtering assembly 120. The first color resist layer 121 and the second color resist layer 122 are connected.

[0081] In this embodiment, the display module 100 surrounds the display screen 110 with a first color resist layer 121 and a second color resist layer 122 along the rotation direction of the light filtering assembly 120. On one hand, when the first light-emitting device 111 emits light, the first color resist layer 121 can rotate relative to the display screen 110 along the rotation axis V2 surrounding the light filtering assembly 120, moving to the light-emitting side of the display screen 110 and overlapping with the display screen 110 along the thickness direction V1, thereby filtering the light incident on the light-emitting side of the display screen 110. On the other hand, when the second light-emitting device 112 emits light, the second color resist layer 122 can rotate relative to the display screen 110 along the rotation axis V2 surrounding the light filtering assembly 120, moving to the light-emitting side of the display screen 110 and overlapping with the display screen 110 along the thickness direction V1, thereby filtering the light incident on the light-emitting side of the display screen 110.

[0082] Optionally, please refer to Figure 6 and Figure 7 The third color resist layer 123 includes a third flexible color resist layer (not shown in the figure). The third color resist layer 123 is located on the outside of the display screen 110. Along the rotation direction of the light filtering assembly 120, the third color resist layer 123 is located between the first color resist layer 121 and the second color resist layer 122, and is connected to the first color resist layer 121 and the second color resist layer 122.

[0083] Please see Figure 7 and Figure 8In some embodiments, the display module 100 includes a second drive member 150, which is disposed on one side of the display screen 110 along the extension direction of the rotation axis V2 of the light filtering assembly 120; the output end of the second drive member 150 contacts the side of the first color resist layer 121 and / or the second color resist layer 122 away from the display screen 110, and is used to drive the first color resist layer 121 and the second color resist layer 122 to rotate.

[0084] In this embodiment, the display module 100 contacts the output end of the second driving member 150 with the side of the first color resist layer 121 and / or the second color resist layer 122 away from the display screen 110. This allows the first color resist layer 121 to automatically rotate relative to the display screen 110 under the drive of the second driving member 150, along the rotation direction of the light filtering component 120, thereby saving manpower.

[0085] Optionally, please refer to Figure 6 and Figure 8 A roller 151 is fitted onto the output end of the second driving component 150. Along the rotation axis V2 of the light filtering assembly 120, the roller 151 is located on one side of the display screen 110. The rotation axis of the roller 151 is parallel to the thickness direction V1 of the display screen 110. The first color resist layer 121 and / or the second color resist layer 122 are located between the roller 151 and the display screen 110. Thus, the first color resist layer 121 and the second color resist layer 122 can rotate to the light-emitting side of the display screen 110 under the drive of the roller 151.

[0086] Please see Figure 1 This application also proposes an image generation unit 10, which includes a display module 100, a housing 200, and a reflector assembly 300. The housing 200 encloses a receiving cavity 210, and a light-transmitting hole 220 is provided on the housing wall of the housing 200, which communicates with the receiving cavity 210. The display module 100 is located inside the receiving cavity 210, and a light filtering assembly 120 of the display module 100 is located between the display screen 110 of the display module 100 and the light-transmitting hole 220. The reflector assembly 300 is located inside the receiving cavity 210; the reflector assembly 300 is used to reflect the light emitted by the display module 100 into the light-transmitting hole 220.

[0087] In this embodiment, the image generation unit 10, by placing the display module 100 in the receiving cavity 210 of the housing 200, can isolate the display module 100 from the external environment, reducing the corrosion caused by external dust or moisture to the display module 100 and increasing the service life of the display module 100. By providing a light-transmitting hole 220 on the shell wall of the housing 200 and placing the reflector assembly 300 in the receiving cavity 210, the light emitted by the display screen 110 of the display module 100, after being filtered by the light filtering assembly 120, is reflected by the reflector assembly 300 and passes through the light-transmitting hole 220, leaving the receiving cavity 210 of the housing 200 and exiting the housing 200. It is important to emphasize that by using the reflector assembly 300 to reflect the light emitted from the display module 100 into the light-transmitting hole 220, the requirements for the placement of the light-transmitting hole 220 can be reduced, so that the light-transmitting hole 220 does not need to be placed in the light-emitting direction of the display module 100. Furthermore, when light from the image generation unit 10 passes through the light-transmitting hole 220 to the reflector assembly 300 and is emitted by the reflector assembly 300 towards the display module 100, the filter assembly 120 of the display module 100 also filters this light, reducing the amount of light entering the display module 100 and lowering the risk of damage to the display module 100.

[0088] In summary, the image generation unit 10 in this embodiment, through the above-mentioned settings, can reduce the risk of damage to the display module 100 and extend the service life of the display module 100.

[0089] Please see Figure 1 In some embodiments, the reflector assembly 300 includes a first reflector 310 and a second reflector 320. The first reflector 310 is at least partially disposed on the side of the light filtering assembly 120 opposite to the display screen 110; the second reflector 320 is disposed opposite to the first reflector 310 along a first direction (not shown), which intersects the direction from the display screen 110 to the light-transmitting aperture 220. The first reflector 310 reflects light emitted from the display screen 110 to the second reflector 320, and the second reflector 320 reflects light into the light-transmitting aperture 220. Optionally, the first direction is parallel to the rotation axis V2 of the light filtering assembly 120.

[0090] In this embodiment, the light emitted by the display screen 110 of the image generation unit 10 and the display module 100 is filtered by the light filtering component 120 and then directed towards the first reflector 310. The light is then reflected by the first reflector 310 and directed towards the second reflector 320. Finally, the light is reflected by the second reflector 320 into the light-transmitting hole 220 and exits the receiving cavity 210 of the housing 200 through the light-transmitting hole 220, and then exits the housing 200.

[0091] Please see Figure 1 In some embodiments, the surface of the first reflector 310 near the display screen 110 is configured as a first reflective surface 311, and the angle A between the first reflective surface 311 and the surface of the display screen 110 near the first reflector 310 is an acute angle; and / or, the surface of the second reflector 320 near the first reflector 310 is a second reflective surface 321, and the second reflective surface 321 is recessed in the direction away from the first reflector 310.

[0092] In this embodiment, the light emitted by the display screen 110 of the image generation unit 10 and the display module 100 is filtered by the light filtering component 120 and then directed towards the first reflective surface 311 of the first reflector 310. Reflected by the first reflective surface 311, the light then travels towards the second reflective surface 321 of the second reflector 320, and is finally reflected by the second reflective surface 321 into the light-transmitting hole 220. The light then exits the housing 200 through the light-transmitting hole 220 and out of the housing 200. By setting the angle A between the first reflective surface 311 and the surface of the display screen 110 closest to the first reflector 310 to an acute angle, more of the light emitted by the display screen 110 towards the first reflective surface 311 is reflected by the first reflective surface 311 towards the second reflective surface 321. By setting the second reflective surface 321 to be recessed in the direction away from the first reflective mirror 310, more of the light reflected from the first reflective surface 311 to the second reflective surface 321 can be reflected into the light-transmitting hole 220 by the second reflective surface 321.

[0093] Please see Figure 1 This application also proposes a human-computer interaction system 1 for a car head-up display, including an image generation unit 10 and a windshield 20. The windshield 20 is located in the light-transmitting hole 220 of the image generation unit 10, on the side opposite to the display module 100 of the image generation unit 10.

[0094] In this embodiment, the human-computer interaction system 1 for the car head-up display has a light emitted from the display screen 110 of the display module 100. After being filtered by the light filtering component 120, the light is reflected by the reflector component 300 and passes through the light-transmitting hole 220. The light then leaves the receiving cavity 210 of the housing 200 through the light-transmitting hole 220, exits the housing 200, and is directed towards the windshield 20. The light is then reflected by the windshield 20 to the side of the windshield 20 away from the image generation unit 10 to form a distant virtual image, thus providing driving assistance to the car driver.

[0095] In addition, when light from the image generation unit 10 passes through the light-transmitting hole 220 to the reflector assembly 300 and is emitted by the reflector assembly 300 to the display module 100, the filter assembly 120 of the display module 100 will also filter the light, reducing the amount of light entering the display module 100 and lowering the risk of damage to the display module 100.

[0096] In summary, the human-computer interaction system 1 of the car head-up display in this embodiment can assist the driver and reduce the light entering the display module 100.

[0097] Please see Figure 1 In some embodiments, the human-machine interaction system 1 of the car head-up display includes a transparent dust cover 30, which is located between the windshield 20 and the image generation unit 10. The orthogonal projection of the transparent dust cover 30 onto the image generation unit 10 from the windshield 20 to the image generation unit 10 covers the light-transmitting hole 220. A dust collection groove 31 is provided on the side of the transparent dust cover 30 away from the light-transmitting hole 220, and the dust collection groove 31 is recessed in the direction close to the light-transmitting hole 220.

[0098] In this embodiment, the human-machine interface system 1 of the car head-up display 1 emits light from the display screen 110 of the display module 100. After exiting the housing 200 through the light-transmitting hole 220, the light passes through the transparent dust cover 30 and is reflected by the windshield 20. By placing the transparent dust cover 30 between the windshield 20 and the image generation unit 10, the orthogonal projection of the transparent dust cover 30 onto the image generation unit 10 covers the light-transmitting hole 220, thus sealing the light-transmitting hole 220 and preventing dust from the side of the windshield 20 near the image generation unit 10 from entering the housing 200 through the light-transmitting hole 220. By providing a dust collection groove 31 on the side of the transparent dust cover 30 away from the light-transmitting hole 220, and by recessing the dust collection groove 31 towards the light-transmitting hole 220, the dust collection groove 31 can better accommodate dust.

[0099] This application also proposes a car (not shown) including a human-machine interaction system 1 with a head-up display.

[0100] In this embodiment of the car, the light emitted from the display screen 110 of the display module 100 is filtered by the light filtering component 120 and then reflected by the reflector component 300. The light passes through the light-transmitting hole 220, exits the housing cavity 210 of the housing 200 through the light-transmitting hole 220, exits the housing 200, and is reflected by the windshield 20. It then forms a distant virtual image on the side of the windshield 20 away from the image generation unit 10, thus providing driving assistance to the car driver.

[0101] In addition, when light from the image generation unit 10 passes through the light-transmitting hole 220 to the reflector assembly 300 and is emitted by the reflector assembly 300 to the display module 100, the filter assembly 120 of the display module 100 will also filter the light, reducing the amount of light entering the display module 100 and lowering the risk of damage to the display module 100.

[0102] In summary, the car in this embodiment can provide driving assistance to the driver and reduce the amount of light entering the display module 100.
