Description

Technical Field

[0001] This disclosure relates to an electronic device, and more particularly to an electronic device installed in a vehicle with a windshield. Background Technology

[0002] Panoramic head-up displays (PHUDs) represent the future trend, but due to placement limitations (such as horizontal placement rather than vertical placement), they are prone to dust accumulation, leading to a decline in display quality. Furthermore, because PHUDs are positioned far from the user, manual cleaning is difficult. Therefore, effectively cleaning PHUDs to mitigate dust accumulation has become a pressing issue. Summary of the Invention

[0003] This disclosure relates to an electronic device installed in a vehicle with a windshield that can have better display quality.

[0004] According to an embodiment disclosed herein, an electronic device installed in a vehicle with a windshield includes a display module, a cleaning module, and a dust collection module. The display module includes a light-emitting unit and a cover layer. The light-emitting unit is adapted to emit a light beam. The cover layer is disposed on and overlaps the light-emitting unit. The windshield and the display module are disposed opposite each other. The light beam penetrates the cover layer and reaches the windshield, allowing a virtual image to be observed formed behind the windshield by a human eye. The cleaning module and the dust collection module are respectively disposed on opposite sides of the display module. At least a portion of the cleaning module is adjacent to the cover layer, while the dust collection module has an opening adjacent to the cover layer.

[0005] Based on the above, in the embodiments disclosed herein, the electronic device includes a cleaning module and a dust collection module disposed on opposite sides of the display module, wherein at least a portion of the cleaning module is adjacent to the cover layer, and the opening of the dust collection module is adjacent to the cover layer. By design, the cleaning module can clean dirt (such as dust) on the surface of the display module and collect it in the dust collection module, thereby reducing / avoiding the impact of dirt on the display quality of the electronic device.

[0006] To make the above-mentioned features and advantages disclosed herein more apparent and understandable, specific embodiments are described below in conjunction with the accompanying drawings. Attached Figure Description

[0096] This disclosure can be understood by referring to the following detailed description in conjunction with the accompanying drawings. It should be noted that, for ease of understanding and for the sake of brevity, many of the drawings in this disclosure depict only a portion of the electronic device, and certain components in the drawings are not drawn to scale. Furthermore, the number and dimensions of the components in the drawings are for illustrative purposes only and are not intended to limit the scope of this disclosure.

[0097] Throughout this specification and the appended claims, certain terms are used to refer to specific elements. Those skilled in the art will understand that electronic device manufacturers may use different names to refer to the same elements. This document is not intended to distinguish between elements that function identically but have different names.

[0098] In the following description and claims, the words “containing” and “including” are open-ended terms, and therefore should be interpreted as “containing but not limited to…”.

[0099] Furthermore, relative terms such as "below" or "bottom" and "above" or "top" may be used in the embodiments to describe the relative relationship of one element of the figures to another element. It is understood that if the apparatus in the figures is flipped so that it is upside down, the element described as being on the "below" side will become the element on the "above" side.

[0100] In some embodiments disclosed herein, terms such as "connection" and "interconnection," unless specifically defined, may refer to two structures in direct contact, or to two structures not in direct (indirect) contact, wherein another structure is disposed between the two structures. Furthermore, these terms regarding engagement and connection may also include situations where both structures are movable or both structures are fixed. In addition, the term "coupling" includes the transfer of energy between two structures through direct or indirect electrical connection, or the transfer of energy between two separate structures through mutual induction.

[0101] It should be understood that when an element or membrane is referred to as being "on" or "connected" to another element or membrane, it can be directly on or directly connected to that other element or membrane, or there may be an inserted element or membrane between them (indirect cases). Conversely, when an element is referred to as being "directly" on or "directly connected" to another element or membrane, there may be no inserted element or membrane between them.

[0102] The terms “approximately,” “equal to,” “same,” “substantially,” or “roughly” are generally interpreted as being within 20% of a given value or range, or as being within 10%, 5%, 3%, 2%, 1%, or 0.5% of a given value or range.

[0103] In this disclosure, the area, width, thickness, or height of each component, or the distance or spacing between components, can be measured using an optical microscopy (OM), a scanning electron microscope (SEM), an alpha-step thickness gauge, an ellipsometry, or other suitable methods. Specifically, according to some embodiments, a scanning electron microscope can be used to obtain a cross-sectional structural image including the component to be measured, and to measure the area, width, thickness, or height of each component, or the distance or spacing between components.

[0104] In this disclosure, roughness judgment is defined by SEM observation, where the peaks and valleys of surface undulations on an uneven surface have a distance difference of 0.15 micrometers (μm) to 1 μm. Roughness judgment measurement can involve using SEM, transmission electron microscope (TEM), etc., to observe the surface undulations at an appropriate magnification, and comparing the undulations by taking a sample of unit length (e.g., 10 μm) to determine its roughness range. Here, "appropriate magnification" means that at least one surface can show at least 10 undulating peaks in the field of view at this magnification, indicating a roughness (Rz) or average roughness (Ra).

[0105] As used herein, the terms “film” and / or “layer” can refer to any continuous or discontinuous structure and material (such as materials deposited by the methods disclosed herein). For example, films and / or layers can include two-dimensional materials, three-dimensional materials, nanoparticles, or even partial or complete molecular layers, or partial or complete atomic layers, or atomic and / or molecular clusters. Films or layers may contain materials or layers with pinholes and may be at least partially continuous.

[0106] Although the terms first, second, third… can be used to describe multiple components, the components are not limited to these terms. These terms are used only to distinguish a single component from other components in the specification. The same terms may not be used in the claims, but rather replaced by first, second, third… in the order of the elements declared in the claims. Therefore, in the following description, a first component may be a second component in the claims.

[0107] Unless otherwise defined, all terms used herein (including technical and scientific terms) have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure pertains. It is understood that these terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning consistent with the relevant art and the context of this disclosure, and should not be interpreted in an idealized or overly formal manner, unless specifically defined herein.

[0108] It should be understood that the technical features of several different embodiments can be replaced, reorganized, or mixed to complete other embodiments without departing from the spirit of this disclosure.

[0111] Figure 1A This is a schematic diagram showing the relative position of an electronic device and a windshield according to an embodiment of the present disclosure. Figure 1B yes Figure 1A A schematic diagram of the electronic device. Figure 1C yes Figure 1A A schematic diagram of an electronic device from another perspective.

[0112] Please also refer to Figure 1A , Figure 1B as well as Figure 1C An electronic device 100a installed in a vehicle having a windshield G includes a display module 110, a cleaning module 120a, and a dust collection module 130a. The display module 110 includes a light-emitting unit 112 and a cover layer 114. The light-emitting unit 112 is adapted to emit a light beam L. The cover layer 114 is disposed on and overlaps the light-emitting unit 112. The windshield G is disposed opposite to the display module 110. The light beam L penetrates the cover layer 114 and forms an image M on the windshield G. The cleaning module 120a and the dust collection module 130a are respectively disposed on opposite sides of the display module 110. At least a portion of the cleaning module 120a is adjacent to the cover layer 114, while the dust collection module 130a has an opening 132 adjacent to the cover layer 114.

[0113] In detail, the vehicle with a windshield G can be, for example, a car, and the electronic device 100a can be installed in the vehicle, such as a car, ship, or airplane, for use by passengers or the driver, but is not limited thereto. The display module 110 is disposed in a receiving groove S, wherein the receiving groove S has a first side S1 and a second side S2 opposite to each other, and a third side S3 and a fourth side S4 connecting the first side S1 and the second side S2 and opposite to each other. The cleaning module 120a and the dust collection module 130a are respectively disposed on the first side S1 and the second side S2 of the receiving groove S. In one embodiment, the display device A in the display module 110 (e.g., ...) Figure 2BThe display device A in the display module 110 may be a non-self-emissive display device, such as a liquid crystal display (LCD) or a quantum dot display (QLED), but is not limited thereto. In one embodiment, the display device A in the display module 110 may also be a self-emissive display module, such as an inorganic light-emitting diode display (LED) or an organic light-emitting diode display (OLED), but is not limited thereto.

[0114] Furthermore, the display device A in the display module 110 includes multiple light-emitting units 112 (such as... Figure 2B The multiple light-emitting units 112 may be, for example, light-emitting diode chips or organic light-emitting layers, but are not limited thereto. In an embodiment not shown, the display module may also include an optical film disposed on the light-emitting units, wherein the optical film is, for example, a diffuser, prism sheet, brightness enhancement film, anti-reflection or anti-glare film, but is not limited thereto, used to improve the optical performance of the light-emitting units. In an embodiment not shown, the display module may also include an adhesive layer, wherein the cover layer can be disposed on the display device through the adhesive layer. In an embodiment not shown, the cover layer is separately disposed from the display device, wherein the cover layer is disposed above the light-emitting units or covers the display device. In an embodiment not shown, the cover layer is separately disposed from the display device, and there is an angle between the two. Figure 1C As shown, in this embodiment, the cover layer 114 and the light-emitting unit 112 overlap each other in the normal direction N of the display module 110. Furthermore, the display device A in this embodiment also includes a substrate 111, wherein the substrate 111 and the cover layer 114 are parallel to each other. The substrate 111 is, for example, a substrate with active and passive components, but is not limited thereto. In another embodiment, the display module 110 further includes a heat sink 116 disposed below the substrate 111 of the display device A, but is not limited thereto. Please refer again to... Figure 1A and Figure 1CThe windshield G and the display module 110 are disposed opposite each other, with the windshield G and the display module 110 forming an angle. The light beam L emitted by the light-emitting unit 112 in the display module 110 penetrates the cover layer 114 and is projected onto the windshield G, so that the human eye can observe that the image M is formed behind the windshield G. That is, the light beam L penetrates the cover layer 114 and shines on the windshield G, so that the human eye can observe that the image M is formed behind the windshield G. At this time, the image M is, for example, a virtual image. The aforementioned "the windshield G and the display module 110 forming an angle" means that the display module 110 is obliquely positioned so that the outline shape of the virtual image M is approximately consistent with the outline of the light-emitting area A1 of the display module 110. In other words, the arrangement of "the windshield G and the display module 110 forming an angle" can reduce the problem of virtual image M distortion. In this embodiment, the image M is formed on the windshield G, but it is not limited to this. In one embodiment, the image M may be formed on a transparent layer or a translucent layer. In one embodiment, image M may also be formed on a window, glass, acrylic sheet, or suitable imaging layer.

[0115] Next, please refer to Figure 1BIn this embodiment, the cleaning module 120a can be, for example, an air blowing device. The airflow F blown out by the cleaning module 120a flows across the surface of the cover layer 114 of the display module 110 to blow dirt (such as dust) on the surface of the cover layer 114 to the opening 132 of the dust collection module 130a located on the opposite side of the cleaning module 120a. The opening 132 then collects the dirt (such as dust) into the dust collection module 130a by suction. That is, this embodiment cleans the surface of the display module 110 using a non-contact cleaning module 120a. More specifically, the air source for the cleaning module 120a can be a separate fan system or the vehicle's air conditioning system, but is not limited thereto. In this embodiment, at least a portion of the cleaning module 120a adjacent to the cover layer 114 refers to the air outlet of the cleaning module 120a being adjacent to the cover layer 114, so that the airflow F blown out by the cleaning module 120a can remove dirt from the surface of the cover layer 114. In one embodiment, the air outlet of the cleaning module 120a can be an elongated opening. In another embodiment, the air outlet of the cleaning module 120a can be composed of multiple separate openings arranged in a row, wherein the smaller openings blow out a smaller volume of air, while the opening 132 of the dust collection module 130a can draw in a larger volume of air, thereby suppressing dust. In one embodiment, the wind speed can be measured, for example, using an anemometer, which is placed near the air outlet and near the air extraction opening for measurement. In an embodiment not shown, the surface of the cover layer can also have a protruding structure, which allows the airflow from the cleaning module 120a to easily disturb the dust. In an embodiment not shown, the side of the display module 110 can also have a protruding structure, which allows the airflow from the cleaning module 120a to easily disturb the dust. In one embodiment, the surface of the cover layer can have an anti-fouling layer, making it difficult for dirt to adhere.

[0116] In addition, please refer to the following: Figure 1B as well as Figure 1CIn this embodiment, the cleaning module 120a may further include a detection component 125. The detection component 125 may be disposed on the third side S3 and / or the fourth side S4 of the receiving groove S, for detecting the degree of dirt and the type of dirt (such as dust or oil stains) on the surface of the covering layer 114. After detection, the cleaning module 120a may selectively perform the corresponding cleaning method for different types of dirt. For example, dust may be cleaned by blowing air, and oil stains may be cleaned by wiping. In one embodiment, the detection component 125 may be, for example, infrared detection, visible light detection, haze detection, or electrical detection (capacitance or resistance), but is not limited thereto. In one embodiment, the air outlet 124 of the cleaning module 120a may be disposed on either side of the receiving groove S, while the opening 132 of the dust collection module 130a is disposed on the opposite side of the cleaning module 120a, that is, the air outlet 124 of the cleaning module 120a and the opening 132 of the dust collection module 130a are respectively disposed on opposite sides of the display module 110. In one embodiment, the air outlet 124 of the cleaning module 120a can be disposed on multiple sides of the receiving groove S, while the opening 132 of the dust collection module 130a is disposed on one of the remaining sides of the receiving groove S. In a non-rectangular display module, the relative arrangement of the air outlet 124 and the opening 132 can increase the smoothness of the airflow F from the air outlet 124 to being drawn in by the opening 132, thereby improving cleaning efficiency.

[0117] In short, in this embodiment, the electronic device 100a includes a cleaning module 120a and a dust collection module 130a disposed on opposite sides of the display module 110. The air outlet of the cleaning module 120a is adjacent to the cover layer 114, while the opening 132 of the dust collection module 130a is adjacent to the cover layer 114. By design, the non-contact cleaning module 120a can clean dirt (such as dust) on the surface of the display module 110 and collect it in the dust collection module 130a, thus reducing / avoiding the impact of dirt on the display quality of the electronic device 100a. Furthermore, the cleaning module 120a in this embodiment also includes a detection component 125 to detect the degree and type of dirt.

[0118] It should be noted that the following embodiments use the component reference numerals and some content from the foregoing embodiments, with the same reference numerals used to represent the same or similar components, and descriptions of the same technical content omitted. For explanations of the omitted parts, please refer to the foregoing embodiments; these will not be repeated in the following embodiments.

[0119] Figure 2A This is a top view schematic diagram of an electronic device according to another embodiment of the present disclosure. Figure 2B It is along Figure 2A A cross-sectional view of line II. Please refer to the diagram below. Figure 1B and Figure 2AThe electronic device 100b in this embodiment is similar to the electronic device 100a described above, except that in this embodiment, the cleaning module 120b further includes an auxiliary device 140b, wherein the nozzle 142b of the auxiliary device 140b is adjacent to the cover layer 114 of the display module 110, and the auxiliary device 140b may be, for example, a detection component 125. Figure 2B A dust blowing device or a vibration device (such as an ultrasound) can assist in detecting, dusting or vibrating the covering layer 114.

[0120] In detail, at Figure 2A In a top view, display module 110 has a first side 115 and a second side 117 opposite to each other, and a third side 118 and a fourth side 119 opposite to each other. Cleaning module 120b is adjacent to the first side 115 of display module 110, and cleaning module 120b includes a ventilation duct 122 and an air outlet 124 connected to the ventilation duct 122, wherein air outlet 124 is adjacent to cover layer 114. Cleaning module 120b may be an air conditioning system, such as an in-vehicle air conditioning system or an independent air conditioning system, but is not limited thereto. In one embodiment, controller 160 may be selectively disposed at air outlet 124 to control the direction of airflow. In one embodiment, cleaning module 120b includes a top cover D1, wherein the bottom B1 of top cover D1 is at a horizontal height higher than cover layer 114. In a cross-sectional view, the orthographic projection of sidewall W1 of top cover D1 onto cover layer 114 overlaps with cover layer 114, and sidewall W1 may be planar or non-planar. In one embodiment, the extension direction of the sidewall W1 is different from the extension direction of the bottom B1 of the top cover D1. The design of the top cover D1 reduces dust during cleaning, thus minimizing driving discomfort. In one embodiment, the material of the top cover D1 may be, for example, plastic or metal, but is not limited thereto. The cleaning module 120b also includes a detection component 125 for detecting the degree of dirt on the cover layer 114. In one embodiment, the electronic device 100b may further include a diverter 150 disposed between the display module 110 and the cleaning module 120b to disperse the airflow F, allowing the airflow F to flow over the upper and lower surfaces (i.e., both sides) of the display module 110. In one embodiment, the airflow F flowing over the heat sink can improve heat dissipation efficiency.

[0121] Furthermore, the dust collection module 130b is located adjacent to the second side 117 of the display module 110 to facilitate the collection of dirt, and the dust collection module 130b may also include a dust collection space 134, wherein the dust collection space 134 is connected to the opening 132. In one embodiment, the number of openings 132 may be one or more. In one embodiment, the dust collection space 134 is, for example, a dust collection box. Furthermore, the dust collection module 130b of this embodiment may also include an air extraction component 136 disposed within the dust collection space 134. In one embodiment, the air extraction component 136 is, for example, a fan air extraction device. The dust collection module 130b of this embodiment may also include a filter component 138 disposed within the dust collection space 134. In one embodiment, the filter component 138 is, for example, a replaceable filter. Dirt can be guided to the filter component 138 for dust filtration by the air extraction component 136. In an embodiment not shown, the electronic device may include a replacement port through which the filter can be replaced. In one embodiment, the replacement port may not have a cover, which can increase the convenience of replacing the filter, but is not a limitation thereof. Additionally, the replacement port may be located below the user's eye level, improving aesthetics. In one embodiment, the dust collection module 130b may further include a detection component 135 for detecting the degree and type of dirt in the air (such as dust). In one embodiment, the detection component 135 may be, for example, infrared detection, visible light detection, haze detection, or electrical detection (capacitance or resistance), but is limited thereto. In one embodiment, the dust collection module 130b includes an upper cover D2, the bottom B2 of which is at a higher level than the cover layer 114.

[0122] Next, please refer to the following: Figure 2A and Figure 2B, in this embodiment, the cover layer 114 and the light-emitting unit 112 overlap each other in the normal direction N of the display module 110. The cover layer 114 can be fixed to the display device A through the adhesive layer 113. In an embodiment, the distance between the light-emitting unit 112 and the cover layer 114 is, for example, between 0 and 10 cm, or between 0 and 0.1 cm, and the measurement method is along the normal direction N, measuring from the side of the cover layer 114 close to the light-emitting unit 112 to the upper surface of the light-emitting unit 112. In an embodiment, the ratio of the distance h3 between the light-emitting unit 112 and the cover layer 114 to the thickness h4 of the cover layer 114 is between 0 and 1000, that is, 0 < h3 / h4 < 1000. In an embodiment, the thickness of the cover layer 114 is, for example, between 0.1 mm and 1 mm. Furthermore, the substrate 111 of the display module 110 in this embodiment and the cover layer 114 are parallel to each other, and the display module 110 has a light-emitting area A1 and a non-light-emitting area A2. In an embodiment, the light-emitting area A1 can be regarded as the display area, and the non-light-emitting area A2 can be regarded as the non-display area, such as the peripheral area. In an embodiment, the display module 110 may also include a light-shielding layer SD, which is disposed on the adhesive layer 113 and located in the non-light-emitting area A2 for light-shielding or covering the peripheral area circuit.

[0123] to the area of the light-emitting area A1 is, for example, between 0.7 and 1.5. In an embodiment, the ratio of the area of the cover layer 114 to the area of the light-emitting area A1 is, for example, between 1.0 and 1.3. In an embodiment, the area of the virtual image M can be obtained by measurement and calculation. Specifically, a detection device (such as a Camera, CCD (Charge Coupled Device)) can be set up on the first side of the imaging layer and has a fixed distance from the imaging layer (representing the user's viewing distance, such as 20 cm to 100 cm). In addition, a scale is placed on the second side of the imaging layer and at the focal position of the virtual image (such as 0.1 cm to 10 m, depending on the optical path length from the display device to the imaging layer). Then, the detection device is focused on the position where the virtual image M is located, and the virtual image projected from the display device to the imaging layer and the scale are photographed to obtain the length and width of the virtual image. The so-called "length and width" refers to "the length and width of the smallest rectangle that can frame the virtual image", and the area of the virtual image M is calculated based on this.

[0134] Figure 6 It is a flowchart of a cleaning program for an electronic device according to an embodiment of the present disclosure. Figure 7 is Figure 6 The system configuration diagram of the electronic device. Please first refer to Figure 7 , in this embodiment, the Controller Area Network (CAN or CAN bus) E0 can control four systems, namely the detection system E1, the display system E2, the electronic control system E3, and the operating system E4.

The operating system E4 at least includes a manual button E41, voice control E42, and gesture E43.

[0135] Next, please refer to the following: Figure 6 and Figure 7 The manual cleaning procedure for the electronic device is as follows: First, in step S201, the surface of the cover layer is detected by a dirt detector in the detection system. Next, in step S202, it is determined whether there is dirt affecting the image display. Next, optionally, step S203, the type of dirt is determined. Next, optionally, step S204, the corresponding cleaning method is determined based on the type of dirt. Next, in step S205, a signal is transmitted to the in-vehicle display system. Next, in steps S206 and / or S207, wherein in step S206, a prompt is displayed on the panoramic head-up display (PHUD); wherein in step S207, a prompt is displayed on the central signal display (CID) / augmented reality head-up display (ARHUD). Next, in step S208, the panoramic head-up display prompts the user to avoid the dirty area. Finally, in step S209, the user initiates the cleaning operation, i.e., manual cleaning is performed after detection. During manual cleaning, the dirt status is detected by the detection system E1, and the corresponding signal is transmitted to the display system E2 via the controller local area network E0. The display system E2 can show the operation interface or prompts. The user can issue control commands through the operating system E4, and the corresponding signal of the control command is transmitted to the electronic control system E3 via the controller local area network E0. The electronic control system E3 can then control the dirt cleaning device E31 to perform cleaning.

[0136] Please refer to the following at the same time: Figure 6 and Figure 7The automatic cleaning procedure for the electronic device begins with step S201, where a dirt detector in the detection system detects the surface of the cover layer. Next, step S202 determines if dirt affecting image display exists. Then, optionally, step S203 determines the type of dirt. Next, optionally, step S204 determines the corresponding cleaning method based on the type of dirt. Next, step S210 transmits a signal to the electronic control system. Finally, step S211 initiates the cleaning operation, which may include blowing air from the air outlet 124 of the cleaning module or bringing the cleaning layer 123 into contact with the cover layer and removing dirt from it. Alternatively, step S212 transmits a signal to the in-vehicle display system. Next, steps S213 and / or S214, where step S213 involves a panoramic head-up display (PHUD); and step S214 involves a central signal display (CID) / augmented reality head-up display (ARHUD). Finally, step S215 displays a prompt to avoid the dirty area. During automatic cleaning, the detection system E1 acquires the dirt level and transmits the corresponding signal to the electronic control system E3 via the controller area network E0. The electronic control system E3 then controls the dirt cleaning device E31 to perform the cleaning. Optionally, the detection system E1 can transmit the signal corresponding to the dirt level to the display system E2 via the controller area network E0, where the display system E2 can display an operation interface (stop automatic cleaning) or a prompt. In another embodiment, the cleaning operation can be performed in response to vehicle startup, or it can be performed periodically, for example, every 5 minutes. This period can be manually adjusted by the user or automatically adjusted by detecting the degree of dirt.
