Description

Technical Field

[0001] This case relates to a display, and more particularly to a display with a fan. Background Art

[0002] In recent years, the market development of displays has become increasingly prosperous. Displays are widely used in various electronic devices in a variety of application scenarios, such as tablet devices, e-readers, convertible laptop devices, handheld devices, commercial advertising displays, etc.

[0003] In order to make the display suitable for various usage scenarios, it sometimes has a need for orientation adjustment. For example, the display may be rotated to a portrait or landscape orientation for use. At this time, if the display has a fan and the display with the fan is directly rotated for use, the mode of the airflow blown by the fan may not meet the usage requirements. In addition, even if the operation of the fan can be adjusted to meet the usage requirements, the adjustment still needs to be carried out specifically for the fan. In either case, this will make the operation of the display in different usage scenarios more difficult. Summary of the Invention

[0004] Therefore, to solve the foregoing problems, this case provides a display, which includes a display module, a fan, and a control module. The display module has a display surface and a back shell. The back shell wraps the display module and forms an accommodation space between the back shell and the display module. The display module can be selectively set in a first orientation or a second orientation. The fan is located inside the back shell, and the fan has a first state corresponding to the first orientation and a second state corresponding to the second orientation. The control module is located inside the back shell and is connected to the display module and the fan. The control module drives the display module to display a menu window on the display surface, and the control module receives a selection instruction through the menu window. When the control module drives the display module to display the display surface corresponding to the first orientation or the second orientation according to the selection instruction, the control module controls the fan to be adjusted to the first state or the second state correspondingly.

[0005] By receiving the selection instruction through the menu window and adjusting both the display mode of the display module and the fan according to the selection instruction, it is possible to control the state of the fan while selecting the screen display direction, thereby solving the above problems.

[0006] Furthermore, there are heat-generating components such as a processor and a display module inside the display, so waste heat will accumulate inside the device.

[0007] However, if the display with a fan is rotated for use, it will cause a change in the heat dissipation air field or flow path inside the display. If a correct and effective heat dissipation air field or flow path is not established as soon as possible, at this time, the air flow blown by the fan for the display may not only fail to assist in the uniform distribution of heat inside the display, but may even interfere with it. Therefore, if the fan is not adjusted after the display is rotated, or there may be an adjustment for the fan but it is accidentally adjusted incorrectly, it may result in a heat dissipation air field or flow path that is not conducive to the uniform distribution of heat when the fan operates. In either case, since the operation of the fan at this time is of no help or even harmful to the uniform distribution of heat inside the display, the operation of the fan at this time is a low-efficiency operation or even an additional energy consumption.

[0008] Therefore, in some embodiments of the present case, when the control module in the display drives the display module to change the display surface from the corresponding first orientation to the corresponding second orientation according to the selection instruction, the control module further cooperates with the natural flow direction of the internal hot air flow of the display at the second orientation to control the fan.

[0009] It is known that hot air has a natural tendency to move from bottom to top (i.e., from a place with lower gravitational potential energy to a place with higher gravitational potential energy) because its density is lower than that of normal-temperature air, and thus has a "natural flow direction of hot air flow". In other words, the natural flow direction of hot air flow is opposite to the direction of gravity. By enabling the control module to control the fan based on control rules related to the natural flow direction of hot air flow, it can generate an air flow that has a lower impact on the natural flow of the internal hot air flow of the display (compared to not adjusting the fan). In this way, the fan inside the display will operate in a manner suitable for the second orientation, enhancing the thermal uniformity inside the display, enabling the fan to operate in a more efficient manner, and thus solving the aforementioned problems.

[0060] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments, but it is not intended to limit the present invention.

[0061] This case provides a display that can be applied to various electronic devices. The display includes a display module, a fan, and a control module. The display module has a display surface, and the control module drives the display module to display a menu window on the display surface. The control module receives a selection instruction through the menu window, and the selection instruction corresponds to the orientation selected by the user. By adjusting the screen display mode of the display surface of the display module and the fan according to the selection instruction, the purpose of simultaneously controlling the screen display direction of the display surface and the fan state can be achieved, thereby solving the problems of "when the display is rotated for use, the air flow mode blown by the fan cannot be adjusted, which may not meet the usage requirements" or "even if the fan can be adjusted, the adjustment still needs to be performed separately for the fan".

[0062] The aforementioned electronic device can be a laptop computer, a desktop computer (set), a workstation, a mobile phone, a tablet computing device, a wearable electronic device, a gaming device, an advertising display for a shopping mall, or other electronic devices, or a part of the aforementioned devices.

[0063] Please refer to Figure 1 and Figure 2 . Figure 1 is a perspective view of a display 1 according to an embodiment of this case.Figure 2 A block diagram drawn according to a display 1 of an embodiment of the present case. In this embodiment, the display 1 has a display module 101, a fan 103, and a control module 104. The display module 101 has a display surface 1011 and a back shell 1012. The display module 101 can display images on the display surface 1011. For example, the display module 101 can be an organic light-emitting diode display (OLED), an electronic paper, a system-integrated panel, a liquid crystal display (LCD), a light-emitting diode display (LED Display), a micro light-emitting diode display (Micro LED Display), a mini light-emitting diode display (Mini LED Display), or a touch display panel (such as a resistive touch panel, a capacitive touch panel, an optical touch panel, or an electromagnetic touch panel), etc.

[0064] In some embodiments, the back shell 1012 covers a part of the display surface 1011 of the display module 101. A receiving space S is formed between the back shell 1012 and the display surface 1011. In some embodiments, the back shell 1012 has a first side wall 1021, a second side wall 1022, a third side wall 1023, and a fourth side wall 1024, where the first side wall 1021 and the second side wall 1022 are opposite to each other, and the third side wall 1023 and the fourth side wall 1024 are opposite to each other.

[0065] The display module 101 can be selectively set in a first orientation FO (for example, as shown in Figure 1 and Figure 3 (A-1), with the first side wall 1021 as the bottommost surface of the display module 101) or a second orientation SO (for example, as shown in Figure 3 (D-1), with the third side wall 1023 as the bottommost surface of the display module 101, but not limited thereto). That is, in the embodiment shown in Figure 3 , the second orientation SO is the orientation obtained by rotating the first orientation FO shown in Figure 3 (A-1) clockwise by 90 degrees (however, in other embodiments, the second orientation SO can be the orientation obtained by rotating the first orientation FO shown in Figure 3 (A-1) clockwise by 180 degrees or 270 degrees). The user can, according to their needs, adjust the display module 101 from the first orientation FO to the second orientation SO (at this time, the display 1 is also adjusted from the first orientation FO to the second orientation SO), or adjust the display module 101 from the second orientation SO to the first orientation FO (at this time, the display 1 is also adjusted from the second orientation SO to the first orientation FO).

[0066] Please refer to Figure 1。In this embodiment, the fan 103 is located within the back shell 1012 and is disposed adjacent to the first side wall 1021 for generating an air flow in a direction away from the first side wall 1021 (similar to that shown in Figure 3 (A-2)). The statement that "the fan 103 is adjacent to the first side wall 1021" means that the distance between the fan 103 and the first side wall 1021 is less than the distances between the fan 103 and the other side walls 1022, 1023, and 1024, and the "fan 103 is adjacent to the first side wall 1021" can be that the distance between the fan 103 and the first side wall 1021 is less than a predetermined value, or the fan 103 is in contact with the first side wall 1021. As shown in Figure 1 , in the illustrated embodiment, the display 1 is in the first orientation FO, and the fan 103 blows air into the accommodation space S. The fan 103 can be an axial flow fan, a centrifugal fan, or a mixed flow fan. In some embodiments, a plurality of fans 103 can also be disposed adjacent to and along the first side wall 1021. However, for the sake of more concise subsequent description of this case, only one fan adjacent to the side wall is shown in the drawings.

[0067] Please continue to refer to Figure 1 and Figure 2 . The control module 104 is located within the back shell 1012 and is connected to the display module 101 and the fan 103 to control the display module 101 and the fan 103. The control module 104 is used to control the operating state of the fan 103, for example, but not limited to, the control module 104 controls the fan 103 in a first state or a second state. Among them, the operating state (the first or second state) can be start (operation), stop (stop operation), increase flow rate (or increase rotational speed), decrease flow rate (or decrease rotational speed), and the flow direction can be specified (for example, by controlling the forward or reverse rotation of the fan blades).

[0068] The control module 104 is used to drive the display module 101 to display an image on the display surface 1011, where the image can include a menu window 1011a (for an example of the display of the menu window, please refer to Figure 3 (B-1)). When the user selects an option in the menu window 1011a, the control module 104 receives a selection instruction corresponding to the selected option (the option can, for example, include "the first orientation FO" and "the second orientation SO", or options corresponding to "the first orientation FO" and "the second orientation SO" described in other ways. The selected option can also be referred to as the selected orientation in this article). After receiving the selection instruction, when the control module 104 drives the display module 101 to display an image on the display surface 1011, the displayed image corresponds to the selected orientation. For example, when the control module 104 drives the display module 101 to display the menu window 1011a on the display surface 1011, and the user selects the first orientation FO, the control module 104 drives the display module 101 to display the display surface 1011 corresponding to the first orientation FO (as shown in Figure 3(B-1)) and control the fan 103 to be in the state corresponding to the first direction FO (also known as the first state, such as Figure 3 (B-2) where the fan 103 in the housing space S blows air into the state). When the user selects the second direction SO, the control module 104 drives the display module 101 to display the display surface 1011 corresponding to the second direction SO (such as Figure 3 (C-1)) and control the fan 103 to be in the state corresponding to the second direction SO (also known as the second state, such as Figure 3 (C-2) the stopped operation state).

[0069] The function of the control module 104 described in this article can be implemented in the form of a software program. For example, the control module 104 includes an instruction set encoded on a machine-readable storage medium and executable by a processor. The processor can call one or more instructions stored in the storage medium and execute it to perform at least one function described in this article according to the at least one instruction called. One or more instructions may include code generated by a compiler or code executed by an interpreter. The readable storage medium can be provided in the form of a non-transitory storage medium. Additionally or alternatively, the control module 104 may include a hardware device that includes an electronic circuit system for implementing the functions described in this article. In addition, there may be a preset correspondence between the fan state and the display direction of the display surface 1011 in the control module 104.

[0070] In summary, by making the control module 104 adjust the display direction of the display surface 1011 and the state of the fan 103 according to the selection instruction (corresponding to the direction selected by the user), the purpose of controlling the state of the fan 103 while selecting the screen display direction can be achieved.

[0071] Hereinafter, referring to Figure 3 (A-1) to Figure 3 (D-2), an embodiment is provided and described as follows. Please first refer to Figure 3 (A-1) and Figure 3 (A-2). Figure 3 (A-1) shows a schematic diagram of the display module 101 in the first direction FO in an embodiment. Figure 3 (A-2) shows the corresponding Figure 3 (A-1), when the control module 104 controls the fan 103 in the first state, a schematic diagram of the air flow direction of the fan 103. Among them, to more clearly represent Figure 3 (A-2) the air flow direction of the fan 103 in Figure 3 (A-2) omits Figure 3The screen displayed on the display surface 1011 in (A-1). The display module 101 (sometimes also represented by the display 1 at the rear) is set to the first orientation FO at this time. The control module 104 drives the display module 101 to display the display surface 1011 corresponding to the first orientation FO and controls the fan 103 to be in the first state (as Figure 3 (A-2) shows. The first state in this embodiment is "operating and blowing air into the accommodation space S"). Since the fan 103 blows air into the accommodation space S, and based on the natural tendency of hot air to rise, the hot air also flows upward from the first side wall 1021; thus, the air flow direction generated by the fan 103 is generally consistent with the natural flow direction of the hot air flow.

[0072] Next, please refer to Figure 3 (B-1) and Figure 3 (B-2). Figure 3 (B-1) shows a schematic diagram of the display module 101 in the first orientation FO and displaying the menu window 1011a. Figure 3 (B-2) shows the corresponding Figure 3 (B-1). When the control module 104 controls the fan 103 to be in the first state, a schematic diagram of the air flow direction of the fan 103. As Figure 3 (B-2) shows, the display 1 is still set to the first orientation FO at this time. Therefore, the control module 104 drives the display module 101 to display the display surface 1011 corresponding to the first orientation FO and controls the fan 103 to be in the first state. The user can, for example, use a remote control, the buttons on the display 1, or directly touch the display surface 1011 of the display 1 (when the display module 101 has a touch function) and other methods to make the control module 104 drive the display module 101 to display a menu window 1011a on the display surface 1011 (as Figure 3 (B-1) shows).

[0073] Please refer to Figure 3 (B-1) and Figure 3 (B-2). When the user selects an option in the menu window 1011a, the control module 104 receives the selection instruction corresponding to the selected option through the menu window 1011a. In this embodiment, the second orientation SO is the orientation obtained by rotating the first orientation FO clockwise by 90 degrees. Therefore, an option corresponding to the second orientation SO can be selected in the menu window 1011a. For example, as Figure 3 (B-1) shows, if the display module 101 is a touch display panel, an option corresponding to the orientation with the third side wall 1023 as the bottom surface can be selected by tapping, so that the control module 104 receives the selection instruction through the menu window 1011a.

[0074] Please continue to refer to Figure 3 (B-1) and Figure 3 (B-2). AsFigure 3 (As shown in (B-2), before the menu window 1011a is called up and the user has not selected an option in the menu window 1011a (that is, before the control module 104 receives a selection instruction through the menu window 1011a), the fan 103 disposed adjacent to the first side wall 1021 in the display 1 is still in the state corresponding to the first orientation FO. In this embodiment, the fan 103 still blows air into the accommodation space S.)

[0075] Next, please refer to Figure 3 (C-1) and Figure 3 (C-2). After the user selects an option in the menu window 1011a, the control module 104 receives a selection instruction through the menu window 1011a. The control module 104 then drives the display module 101 according to the selection instruction to change the display surface 1011 from the display corresponding to the first orientation FO (in this embodiment, the orientation with the first side wall 1021 as the bottommost surface) to the display corresponding to the second orientation SO (in this embodiment, the orientation with the third side wall 1023 as the bottommost surface). Further, as Figure 3 (shown in (C-2), when the control module 104 drives the display module 101 to change the display surface 1011 from the display corresponding to the first orientation FO to the display corresponding to the second orientation SO according to the selection instruction, the control module 104 also controls the state of the fan 103 to be adjusted from "blowing air into the accommodation space S (the first state)" to "closed (the second state)".)

[0076] Next, please refer to Figure 3 (D-1) and Figure 3 (D-2). After receiving the selection instruction through the menu window 1011a and the control module 104 drives the display module 101 to change the display surface 1011 from the display corresponding to the first orientation FO to the display corresponding to the second orientation SO according to the selection instruction, the user can rotate the display 1 clockwise by 90 degrees so that the third side wall 1023 becomes the bottommost surface and then proceed with subsequent use. At this time, as Figure 3 (shown in (D-2), since the control module 104 turns off the fan 103, when the display 1 is in the second orientation SO, compared with the first state (blowing air into the accommodation space S) of the fan 103 when it is in the first orientation FO, the fan 103 does not generate an air flow that interferes with the natural flow of the internal hot air flow of the display 1.)

[0077] It is also worth noting that in such as Figure 3 (A-1) to Figure 3In the embodiment shown in (D-2), after the user first selects an option in the menu window 1011a to cause the control module 104 to receive a selection instruction, the user then physically rotates the display 1. However, in some other embodiments, the user may also first physically rotate the display 1, and then cause the control module 104 to drive the display module 101 to display the menu window 1011a on the display surface 1011, so as to select an option in the menu window 1011a to cause the control module 104 to receive a selection instruction.

[0078] For example, after the menu window 1011a is displayed on the display surface 1011, the user first physically rotates the display 1 (at this time, the display 1 will be as Figure 5 (shown in (B-1)), and then the user selects an option in the menu window 1011a. The control module 104 immediately receives the selection instruction and drives the display module 101 according to the selection instruction, so that the display surface 1011 corresponds to the second direction SO for display (at this time, the display 1 will change from being as Figure 5 (shown in (B-1)) to being as Figure 5 (shown in (C-1)).

[0079] As can be seen from the foregoing embodiments, if the control module 104 cooperates with the natural flow direction of the internal hot air flow of the display 1 in the second direction SO, and the control fan 103 is adjusted from the state corresponding to the first direction FO to the state corresponding to the second direction SO, the interference of the fan 103 on the natural flow of the hot air flow in the second direction SO can be reduced, and the inefficient operation of the fan 103 for the purpose of uniform heat distribution can be reduced. In addition, since there is no need to additionally adjust the state of the fan 103 after rotating the display 1, the possibility that the fan 103 is adjusted to an operation that is not conducive to uniform heat distribution can be reduced.

[0080] Accordingly, in some embodiments of this case, when the control module 104 in the display 1 drives the display module 101 to change the display surface 1011 from corresponding to the first position FO to corresponding to the second position SO according to the selection instruction, the control module 104 can control the state of the fan 103 based on a control rule related to the natural flow direction of the internal hot air flow of the display 1 in the second position SO. For example, the rule can be: when the control module 104 drives the display module 101 to change the display surface 1011 from corresponding to the first position FO to corresponding to the second position SO according to the selection instruction, (1) if the fan 103 is on the side of the natural flow direction of the hot air flow in the second position SO, the control module 104 controls the fan 103 to reduce the amount of air blown into the accommodation space S and perpendicular to the natural flow direction of the hot air flow (compared with the amount of air blown into the accommodation space S by the fan 103 when the display 1 is in at least one other position), (2) if the fan 103 is on the top side of the natural flow direction of the hot air flow in the second position SO, the control module 104 controls the fan 103 to turn off or discharge air to the outside of the display 1, or (3) if the fan 103 is on the bottom side of the natural flow direction of the hot air flow in the second position SO, the control module 104 controls the fan 103 to generate an air flow in the same direction as the natural flow direction of the hot air flow.

[0081] Among them, as described above, the foregoing control method can be achieved by the control module 104 having a preset relationship between the fan state directly corresponding to each option in the menu window 1011a and the screen display direction of the display surface 1011, and the control module 104 directly controls according to this relationship; or, the control module 104 can first obtain the natural flow direction of the internal hot air flow of the display 1 and the position of the fan 103 in the second position SO through the position sensing module 105 (reference can be made to Figure 4 ), then judge the relationship between the fan 103 and the natural flow direction of the hot air flow, and the control module 104 then controls according to this relationship to achieve (this part will be described later).

[0082] Next, please refer to Figure 4 . Figure 4A block diagram drawn for a display according to another embodiment of the present case. In some embodiments, the display 1 may have an orientation sensing module 105, which is located inside the back shell 1012 and connected to the control module 104. The orientation sensing module 105 can be used to detect the orientation of the display 1 / display module 101 and output a signal to the control module 104, so that the control module 104 knows that the orientation of the display 1 / display module 101 has changed. In some embodiments, the orientation sensing module 105 can be an accelerometer, a geomagnetic sensor, a gyroscope, etc. Additionally, since the orientation sensing module 105 can be used to detect the orientation of the display 1 / display module 101, and the natural flow direction of the hot air current is opposite to the direction of gravity, the control module 104 can know the natural flow direction of the hot air current inside the display 1 at a certain orientation through the orientation sensing module 105. Furthermore, the position of the fan 103 at the first orientation FO can be recorded in the control module 104. Then, according to the new orientation of the display 1 / display module 101 detected by the orientation sensing module 105, the position of the fan 103 at the second orientation SO can be known, and the relative position relationship between the fan 103 and the natural flow direction of the hot air current at the second orientation SO can be inferred.

[0083] In some embodiments, when the orientation sensing module 105 senses that the display 1 changes from the first orientation FO to the second orientation SO (such as when the display 1 changes from Figure 5 (A-1) to Figure 5 (B-1)), the control module 104 responds to this change and drives the display module 101 to display a menu window 1011a on the display surface 1011. At this time, the display surface 1011 still corresponds to the first orientation FO for display, and the menu window 1011a that appears can also be displayed on the display surface 1011 in a manner corresponding to the first orientation FO, but it is not limited thereto. By automatically displaying the menu window 1011a on the display surface 1011 after the display 1 rotates, instead of manually calling out the menu window 1011a, the overall operation process becomes more streamlined.

[0084] For example, please refer to Figure 5 (A-1) and Figure 5 (A-2). Figure 5 (A-1) shows a schematic diagram of the display module 101 in the first orientation FO in an embodiment; Figure 5 (A-2) shows corresponding to Figure 5 (A-1), a schematic diagram of the air flow direction of the fan 103 when the control module 104 controls the fan 103 in the first state. Among them, to more clearly show Figure 5 (A-2) the air flow direction of the fan 103 in Figure 5 (A-2) omits Figure 5 (A-1) the picture displayed on the display surface 1011. In Figure 5The display 1 in (A-1) has an orientation sensing module 105 (not shown in Figure 5 (A-1), for reference Figure 4 ). The display module 101 (sometimes also represented by the display 1 at the rear) is set to the first orientation FO at this time. The control module 104 drives the display module 101 to display the display surface 1011 corresponding to the first orientation FO and controls the fan 103 to be in the first state (as Figure 5 (A-2) shows. In this embodiment, the first state is "operating and blowing air into the accommodation space S"). At this time, the air flow direction generated by the fan 103 is substantially the same as the natural flow direction of the hot air flow inside the display 1.

[0085] Next, please refer to Figure 5 (B-1) and Figure 5 (B-2). Figure 5 (B-1) shows a schematic diagram of the display surface 1011 corresponding to the first orientation FO and displaying a menu window 1011a thereon when the display module 101 rotates to the second orientation SO in this embodiment. Figure 5 (B-2) shows the corresponding Figure 5 (B-1), a schematic diagram of the air flow direction of the fan 103 when the control module 104 still controls the fan 103 in the first state. As Figure 5 (B-1) shows, the user first rotates the display 1 90 degrees to the right to make it in the orientation of "with the third side wall 1023 as the bottom surface" (i.e., the second orientation of this embodiment). The display 1 has an orientation sensing module 105. When the orientation sensing module 105 senses that the display 1 changes from the first orientation FO to the second orientation SO, the control module 104 responds to this change and drives the display module 101 to display a menu window 1011a on the display surface 1011. At this time, the display surface 1011 still corresponds to the first orientation FO for display, and the appeared menu window 1011a can also be displayed on the display surface 1011 in a manner corresponding to the first orientation FO. The user selects an option in the menu window 1011a, and the control module 104 receives the selection instruction through the menu window 1011a. In this embodiment, the control module 104 receives a selection instruction corresponding to the orientation of "with the third side wall 1023 as the bottom surface" through the menu window 1011a.

[0086] Continue to refer to Figure 5 (B-1) and Figure 5(B-2). Before the menu window 1011a is called out and the user has not selected an option in the menu window 1011a (that is, before the control module 104 receives a selection instruction through the menu window 1011a), the fan 103 disposed adjacent to the first side wall 1021 in the display 1 is still in the state corresponding to the first orientation FO. In this embodiment, the fan still blows air into the accommodation space S. At this time, since the natural flow direction of the hot air flow inside the display 1 is from the third side wall 1023 to the fourth side wall 1024, the air flow blown out by the fan 103 at this stage will interfere with the natural flow of the hot air flow.

[0087] Next, please refer to Figure 5 (C-1) and Figure 5 (C-2). After the control module 104 receives a selection instruction corresponding to the second orientation through the menu window 1011a, the control module 104 drives the display module 101 according to the selection instruction to change the display surface 1011 from the state corresponding to the first orientation FO (in this embodiment, the orientation with the first side wall 1021 as the bottommost surface) to the state corresponding to the second orientation SO (in this embodiment, the orientation with the third side wall 1023 as the bottommost surface). When the control module 104 drives the display module 101 to change the display surface 1011 from the state corresponding to the first orientation FO to the state corresponding to the second orientation SO according to the selection instruction, the control module 104 also controls the state of the fan 103 to be adjusted from "blowing air into the accommodation space S (the first state)" to "closed (the second state)". Accordingly, when the display 1 is in the second orientation SO, the fan 103 will not generate an air flow that interferes with the natural flow of the hot air flow, thereby reducing the interference of the fan 103 on the natural flow of the hot air flow in the second orientation SO.

[0088] Accordingly, it can be seen that by enabling the display 1 to automatically display the menu window 1011a on the display surface 1011 for operation after rotation, it is possible to achieve the effect that there is no need to call out the menu window 1011a separately, and the overall operation process is more streamlined.

[0089] As long as the menu window 1011a can be used to receive selection instructions, there are no special restrictions on the way it receives selection instructions or the style of the menu. For example, in addition to the aforementioned method of clicking an option by touch to select, in some embodiments, options can also be selected by a remote control, by a button on the display 1, or by a gesture (such as swiping up on the touch display panel), so that the control module 104 receives a selection instruction through the menu window 1011a.

[0090] Regarding the style of the menu, reference can be made to Figure 6 (A), Figure 6 (B), Figure 6 (C). Figure 6 (A),Figure 6 (B), Figure 6 (C) shows a schematic diagram of some embodiments of the menu window 1011a according to the present case. Options can be presented in the menu window 1011a with visual elements (such as static graphics, animations, text, symbols, etc. or combinations thereof). In some embodiments, the menu window 1011a can display the current airflow direction and / or rotational speed generated by the fan 103; the menu window 1011a can also display, among the options, the orientation representative diagrams of the display 1 and the display screen, the airflow direction and / or rotational speed generated by the fan 103 at each corresponding orientation. In some embodiments, in addition to presenting options with visual elements, the options may not be presented on the display surface 1011.

[0091] For example, Figure 6 in the menu window 1011a in (A), the options of "not rotating", "rotating 90 degrees", "rotating 180 degrees", and "rotating 270 degrees" are presented with static graphics; Figure 6 in the menu window 1011a in (B), the options are presented in the form of text and graphics; Figure 6 in the menu window 1011a in (C), the options are not presented on the display surface 1011, and it receives selection instructions by receiving gestures. Different gestures directly correspond to different second orientation SO options. For example, in Figure 6 the menu window 1011a in (C), if it is desired that the second orientation SO changes to have the right side in the current diagram as the bottom surface, a gesture of swiping from right to left can be input on the menu window 1011a.

[0092] Please continue to refer to Figure 6 (A), Figure 6 (B), Figure 6 and (C) and also refer to Figure 7 (A), Figure 7 (B). Figure 7 (A), Figure 7 (B) shows schematic diagrams drawn according to other embodiments of the menu window 1011a of the present case. In some embodiments, the menu window 1011a has a directional element for determining at least two different orientations of the menu window 1011a. The directional element can be the contour of the menu window 1011a itself, the text in the menu, the graphics in the menu, or combinations of the foregoing, etc. Taking the three menu windows 1011a shown in Figure 6 (A), Figure 6 (B), Figure 6 (C) as an example, both the contour of the menu itself and the text in the menu can be regarded as directional elements. Figure 7(A) The menu window 1011a shown has a point-symmetric shape for the outline of the menu itself, which cannot be used as a directional element. However, the text in the menu can be used as a directional element for the menu window 1011a. In some embodiments, when the user already knows the meaning of the menu and how to operate it, the menu may not have text. In this case, the outline of the menu itself or the overall style of the menu can be used as a directional element, as shown in Figure 7 the menu window 1011a in (B). By means of the directional element, it is possible to determine the bottom edge of the menu window 1011a and thus determine its orientation.

[0093] As can be seen from the foregoing description, if the control module 104 controls the state of the fan 103 in accordance with the natural flow direction of the hot air flow inside when the display 1 is in the second orientation SO, it is possible to reduce the interference of the fan 103 on the natural flow of the hot air flow in the second orientation SO, and reduce the inefficient operation of the fan 103 in terms of the goal of uniform heat distribution or even simple energy consumption. Other aspects of the state control of the fan 103 by the control module 104 will be further disclosed below.

[0094] It should be noted first that, in order to make the description and the drawings more concise, for the steps of changing the screen display mode on the display surface 1011, the appearance of the menu window 1011a, the selection of options in the menu, etc. described in the subsequent aspects, reference can be made to the foregoing, and this part will not be repeated. In other words, only the state of the fan 103 after the display 1 is adjusted from the first orientation FO to the second orientation SO will be discussed subsequently, and the description of the change of the screen display mode of the display surface 1011, the calling out of the menu window 1011a, and receiving instructions with the menu window 1011a will not be repeated.

[0095] Please refer to Figure 8 (A-1) and Figure 8 (A-2). Figure 8 (A-1) shows a schematic diagram of the air flow direction of the fan 103 when a display module 101 is in the first orientation FO and the control module 104 controls the fan 103 in the first state in an embodiment. Figure 8 (A-2) shows a schematic diagram of the air flow direction of the fan 103 when the display module 101 rotates 90 degrees clockwise to the second orientation SO and the control module 104 controls the fan 103 in the second state in this embodiment. Figure 8 In (A-1), the first orientation FO of the display 1 is the orientation with the first side wall 1021 as the bottommost surface; Figure 8In (A-2), the second orientation SO is the orientation where the display 1 is rotated 90 degrees clockwise and the third side wall 1023 is the bottommost surface. In the first orientation FO, the fan 103 disposed adjacent to the first side wall 1021 in the display 1, its corresponding state (the first state) in the first orientation FO is to blow air into the accommodation space S. In the second orientation SO, the corresponding state (the second state) of the fan 103 is not closed, but has a lower air volume than when the fan 103 is in the first orientation FO (in the figure, the number of arrows above the fan 103 indicates the relative magnitude of the air volume); in other words, at this time, the fan 103 blows air into the accommodation space S at a relatively low rotational speed.

[0096] Although the fan 103 is not closed in the second orientation SO, compared with the situation where the fan 103 maintains the first state, since the blown air volume has been reduced, it is still possible to reduce the interference of the fan 103 on the natural flow of the hot air flow in the second orientation SO.

[0097] Next, please refer to Figure 8 (B-1) and Figure 8 (B-2). Figure 8 (B-1) shows a schematic diagram of the air flow direction of the fan 103 when the display module 101 is in the first orientation FO and the control module 104 controls the fan 103 in the first state in an embodiment. Figure 8 (B-2) shows a schematic diagram of the air flow direction of the fan 103 when the display module 101 is rotated 180 degrees to the second orientation SO and the control module 104 controls the fan 103 in the second state in this embodiment. In this embodiment, the first orientation FO of the display 1 is the orientation with the first side wall 1021 as the bottommost surface, and the second orientation SO is the orientation where the display 1 is rotated 180 degrees clockwise and the second side wall 1022 is the bottommost surface. In the first orientation FO, the fan 103 disposed adjacent to the first side wall 1021 in the display 1, its corresponding state (the first state) in the first orientation FO is to blow air into the accommodation space S. In the second orientation SO, the fan 103 is on the top side of the natural flow direction of the hot air flow, and the corresponding state (the second state) of the fan 103 in this second orientation SO is closed. Compared with the situation where the fan 103 maintains the original state, making the fan 103 in the closed state in the second orientation SO can avoid the fan 103 generating an air flow in the opposite direction to the natural flow of the hot air flow and interfering with the natural flow of the hot air flow in this second orientation SO.

[0098] Next, please refer to Figure 9 (A-1) and Figure 9(A-2). In some embodiments, there are multiple side walls in the display 1, and fans 103 connected to the control module 104 are disposed adjacent to each of them. The control module 104 controls these fans 103 to adjust their states from the state corresponding to the first orientation FO to the state corresponding to the second orientation SO (however, the state changes of the fans 103 may be different from each other). By disposing the fans 103 on multiple side walls, the display 1 can generate an air flow that conforms to the natural flow direction of the hot air flow corresponding to the second orientation SO in more second orientations SO, thereby helping to achieve a more uniform heat distribution in the display 1 in multiple orientations.

[0099] For example, please refer to Figure 9 (A-1) and Figure 9 (A-2). Figure 9 (A-1) shows a schematic diagram of the air flow directions of the fans 103 when the display module 101 (display 1) is in the first orientation FO and the control module 104 controls the multiple fans 103 to be in the first state in an embodiment. Figure 9 (A-2) shows a schematic diagram of the air flow directions of the fans 103 when the display module 101 (display 1) rotates 180 degrees to the second orientation SO and the control module 104 controls the multiple fans 103 to be in the second state in this embodiment. The display 1 in this embodiment is similar to Figure 3 the display 1 shown in Figure 9 (A-1) and Figure 9 (A-2), except that in the displays 1 of

[0100] Continuing to refer to Figure 9 (A-1) and Figure 9 (A-2). In this embodiment, the first orientation FO of the display 1 is the orientation with the first side wall 1021 as the bottommost surface, and the second orientation SO is the orientation with the second side wall 1022 as the bottommost surface after the display 1 rotates 180 degrees clockwise. In the first orientation FO, for the fans 103 disposed adjacent to the first side wall 1021 in the display 1, their states corresponding to the first orientation FO are to blow air into the accommodation space S; while for the fans 103 disposed adjacent to the second side wall 1022, their states corresponding to the first orientation FO are closed. And as shown in Figure 9 (A-2), in the second orientation SO, the corresponding state of the fans 103 adjacent to the first side wall 1021 is the closed state, and the corresponding state of the fans 103 adjacent to the second side wall 1022 is to blow air into the accommodation space S.

[0101] Based on this, it can be seen that Figure 9 (A-1) and Figure 9Whether the display 1 in (A-2) has the first side wall 1021 as the bottommost surface or the second side wall 1022 as the bottommost surface, an air flow in the same direction as the natural flow direction of the hot air flow at this orientation can be generated inside the display 1. In the presence of such an air flow, the circulation inside the display 1 is better, which helps the heat to be more evenly distributed inside the display 1. Therefore, by providing fans 103 on multiple side walls, the display 1 can have better thermal uniformity in more second orientations SO.

[0102] Therefore, in some embodiments, if fans 103 connected to the control module 104 are provided adjacent to the first side wall 1021, the second side wall 1022, the third side wall 1023, and the fourth side wall 1024 of the display 1, and the control module 104 controls the states of these fans 103 based on control rules related to the natural flow direction of the hot air flow inside the display 1 in the second orientation SO, then regardless of which side wall is used as the bottommost surface in the second orientation SO of the display 1, an air flow in the same direction as the natural flow direction of the hot air flow at this orientation can be generated inside the display 1.

[0103] Next, please refer to Figure 10 . Figure 10 FIG. is a schematic diagram of a display 1 having ventilation holes 106 according to an embodiment of the present case. In some embodiments, the back shell 1012 has ventilation holes 106 (for example, at least one of the first side wall 1021, the second side wall 1022, the third side wall 1023, and the fourth side wall 1024). The fan 103 is used to introduce the gas outside the display 1 into the accommodation space S through the ventilation holes 106 or to discharge the gas in the accommodation space S from the ventilation holes 106. By providing the ventilation holes 106 on the back shell 1012, the heat dissipation of the display 1 can be further assisted.

[0104] Please continue to refer to Figure 10 . In particular, when the first orientation FO has the first side wall 1021 as the bottommost surface and a fan 103 is provided adjacent to the first side wall 1021, if the second side wall 1022 opposite to the first side wall 1021 is provided with ventilation holes 106, then since the air flow blown into the accommodation space S by the fan 103 (which is an air flow in the same direction as the natural flow direction of the hot air flow at this time) can carry the heat to the outside of the display 1 through the ventilation holes 106, this setting can further improve the heat dissipation effect of the display 1 in this orientation.

[0105] In addition, when ventilation holes 106 are provided on the side wall adjacent to the fan 103, the fan 103 can, by controlling its rotation direction, not only discharge the gas inside the display 1 from the adjacent ventilation holes 106, but also introduce external gas into the display 1 from the ventilation holes 106. In other words, at this time, in addition to being used for the internal air circulation of the display 1, the fan 103 can also have a mode of interacting with the external gas of the display 1. For example, the fan 103 can introduce air into the display 1 in a manner that conforms to the natural flow direction of the hot air in the second orientation SO of the display 1, or discharge the air from the display 1 in a manner that conforms to the natural flow direction of the hot air in the second orientation SO, so as to further improve the overall heat dissipation effect of the display 1. It should be noted that the connection line between the center of the ventilation hole 106 provided on the side wall adjacent to the fan 103 and the center of the fan 103 does not necessarily have to be perpendicular to the adjacent side wall. That is to say, the ventilation hole 106 can be arranged in a staggered manner with the fan 103, as long as the fan 103 can achieve the aforementioned "discharging air from the adjacent ventilation hole 106 to the outside of the display 1" and "introducing external gas into the display 1 from the ventilation hole 106".

[0106] Next, please refer to Figure 11 (A-1), Figure 11 (A-2) and Figure 11 (A-3). In some embodiments, if a fan 103 is provided adjacent to the first side wall 1021 and there are ventilation holes 106 on the first side wall 1021, the control of the state of the fan 103 by the control module 104 may include, but is not limited to, the following:

[0107] When the fan 103 is a lateral fan in the second orientation SO of the display 1, the control module 104 can (1) control the fan 103 to turn off, (2) control the fan 103 to reduce the air flow rate blown into the accommodation space S, or (3) control the air guiding direction of the fan 103 to change to discharge to the outside of the display 1.

[0108] For example, for the situation of (3) here, reference can be made to Figure 11 (A-1) and Figure 11(A-2). In this embodiment, the first orientation FO of the display 1 is the orientation with the first sidewall 1021 as the bottommost surface, and the second orientation SO is the orientation with the third sidewall 1023 as the bottommost surface after the display 1 is rotated clockwise by 90 degrees. In the first orientation FO, the fan 103 disposed adjacent to the first sidewall 1021 in the display 1 is in a state of blowing air into the accommodation space S corresponding to the first orientation FO. In the second orientation SO, the corresponding state of the fan 103 is the state of discharging air to the outside of the display 1 through the ventilation holes 106 (in this state, the fan 103 also reduces the amount of air blown into the accommodation space S and perpendicular to the natural flow direction of the hot air flow). Since the fan 103 can take out the air flow inside the display 1 in the second orientation SO, it helps to discharge the heat inside the display 1.

[0109] When the fan 103 is a top-facing fan in the second orientation SO of the display 1, the control module 104 can (1) control the fan 103 to turn off or (2) control the air guiding direction of the fan 103 to discharge to the outside of the display 1.

[0110] For example, in the case of (2) here, reference can be made to Figure 11 (A-1) and Figure 11 (A-3). In this embodiment, the first orientation FO of the display 1 is the orientation with the first sidewall 1021 as the bottommost surface, and the second orientation SO is the orientation with the second sidewall 1022 as the bottommost surface after the display 1 is rotated clockwise by 180 degrees. In the first orientation FO, the fan 103 disposed adjacent to the first sidewall 1021 in the display 1 is in a state of blowing air into the accommodation space S corresponding to the first orientation FO. In the second orientation SO, the corresponding state of the fan 103 is the state of discharging air to the outside of the display 1 through the ventilation holes 106. Since the fan 103 can take out the air flow inside the display 1, it helps to discharge the heat inside the display 1.

[0111] When the fan 103 is a bottom-facing fan in the second orientation SO of the display 1, the control module 104 controls the fan 103 to blow air into the accommodation space S in the second orientation SO of the display 1, and a air flow in the same direction as the natural flow direction of the hot air flow can be generated.

[0112] For example, reference can be made to Figure 12 (A-1) and Figure 12 (A-2). Figure 12 (A-1) shows a schematic diagram of the air flow direction of each fan 103 when the display module 101 (display 1) is in the first orientation FO and the control module 104 controls the plurality of fans 103 in the first state in an embodiment. Figure 12(A-2) shows a schematic diagram of the air flow direction of each fan 103 when the display module 101 (display 1) rotates clockwise by 90 degrees to the second orientation SO in this embodiment, and the control module 104 controls the fans 103 in the second state. As Figure 12 (A-1) shows that in this embodiment, the first orientation FO of the display 1 is the orientation with the first side wall 1021 as the bottom surface, and the second orientation SO is the orientation with the third side wall 1023 as the bottom surface after the display 1 rotates clockwise by 90 degrees. Among them, a fan 103 is adjacent to the first side wall 1021 of the display 1, and there are ventilation holes 106 on the first side wall 1021. Another fan 103 is also adjacent to the second side wall 1022, and there are also ventilation holes 106 on the second side wall 1022. In the first orientation FO, the fan 103 adjacent to the first side wall 1021 in the display 1 blows air into the accommodation space S in the corresponding first orientation FO state; while the fan 103 adjacent to the second side wall 1022 is in the closed state in the corresponding first orientation FO state. And as Figure 12 (A-2) shows that in the second orientation SO, the control module 104 controls the air guiding direction of the fan 103 adjacent to the first side wall 1021 to change to discharge to the outside of the display 1; and controls the fan 103 adjacent to the second side wall 1022 to open and discharge air to the outside of the display 1.

[0113] In this embodiment, when the display 1 is in the first orientation FO, the fan 103 adjacent to the first side wall 1021 can introduce relatively low-temperature gas from the outside into the accommodation space S through the corresponding ventilation holes 106 to help the display 1 cool down. When the display 1 is in the second orientation SO, the fans 103 become the side fans of the display 1. Through the above configuration and control, the display 1 can have two fans 103 to discharge the heat inside the display 1 from their respective corresponding ventilation holes 106 after rotation, so that the display 1 can dissipate heat more effectively in the second orientation SO.

[0114] Next, refer to Figure 12 (B-1) and Figure 12 (B-2). Figure 12 (B-1) shows a schematic diagram of the air flow direction of each fan 103 when the display module 101 (display 1) is in the first orientation FO and the control module 104 controls the multiple fans 103 in the first state. Figure 12(B-2) shows a schematic diagram of the display module 101 (display 1) rotating 90 degrees clockwise to the second orientation SO in this embodiment, and the control module 104 controls the air flow directions of the fans 103 in the second state. In this embodiment, the first orientation FO of the display 1 is the orientation with the first side wall 1021 as the bottommost surface, and the second orientation SO is the orientation with the second side wall 1022 as the bottommost surface after the display 1 rotates 180 degrees clockwise. Among them, a fan 103 is adjacent to the first side wall 1021 of the display 1, and there are ventilation holes 106 on the first side wall 1021. Another fan 103 is also adjacent to the third side wall 1023, and there are ventilation holes 106 on the third side wall 1023. In the first orientation FO, the fan 103 adjacent to the first side wall 1021 in the display 1 blows air into the accommodation space S in the corresponding first orientation FO state; and the fan 103 adjacent to the third side wall 1023 blows air into the accommodation space S in the corresponding first orientation FO state. And as Figure 12 (B-2) shows that in the second orientation SO, the control module 104 controls the air guiding direction of the fan 103 adjacent to the first side wall 1021 to change to discharge to the outside of the display 1; and controls the fan 103 adjacent to the third side wall 1023 to increase the air flow rate blown into the accommodation space S.

[0115] In this embodiment, when the display 1 is in the first orientation FO, the fan 103 adjacent to the first side wall 1021 can introduce relatively low-temperature gas from the outside into the accommodation space S through the corresponding ventilation holes 106 to help cool the display 1. When the display 1 is in the second orientation SO, one of the fans 103 becomes the side fan of the display 1 and the other fan 103 becomes the bottom fan. And through the above configuration and control, the display 1 can have a fan 103 that generates an air flow in the same direction as the natural flow direction of the hot air flow in the display 1 in the second orientation SO after rotation, and also has a fan 103 that discharges the heat inside the display 1 from the corresponding ventilation holes 106, so that the display 1 can dissipate heat more effectively in the second orientation SO.

[0116] As can be seen from the above, by arranging fans 103 and corresponding ventilation holes 106 adjacent to multiple side walls of the display 1, the display 1 can also have better heat dissipation performance in multiple second orientations SO.

[0117] Accordingly, in some embodiments, if fans 103 connected to the control module 104 are disposed adjacent to the first sidewall 1021, the second sidewall 1022, the third sidewall 1023, and the fourth sidewall 1024 of the display 1, and ventilation holes 106 are provided on the first sidewall 1021, the second sidewall 1022, the third sidewall 1023, and the fourth sidewall 1024, and the control module 104 cooperates with the natural flow direction of the hot air flow inside the display 1 in the second orientation SO to control the states of these fans 103, then regardless of which sidewall is used as the bottom surface in the second orientation SO of the display 1, in addition to being able to generate an air flow in the same direction as the natural flow direction of the hot air flow at that orientation inside the display 1 to assist in uniform heat distribution, an air flow for enhancing the heat dissipation effect of the display 1 can also be generated.

[0118] In summary, the present case provides a display 1, which includes a display module 101, fans 103, and a control module 104. The display module 101 has a display surface 1011, and the control module 104 drives the display module 101 to display a menu window 1011a on the display surface 1011. The control module 104 receives a selection instruction through the menu window 1011a. The selection instruction corresponds to a new orientation in which the display 1 is to be used, and causes the display mode of the display surface 1011 of the display module 101 and the fans 103 to be adjusted corresponding to the selection instruction, so as to achieve the purpose of simultaneously controlling the display direction of the display surface 1011 of the display module 101 and the states of the fans 103, thereby solving the aforementioned problems of "when the display is rotated for use, the air flow blowing mode of the fan cannot be adjusted, which may not meet the usage requirements" or "even if the fan can be adjusted, the adjustment still needs to be carried out separately for the fan".

[0119] In addition, by further enabling the control module 104 to cooperate with the natural flow direction of the hot air flow to control the fans 103, the interference of the fans 103 on the natural flow of the hot air flow in the second orientation SO can be reduced, and the inefficient operation of the fans 103 in terms of the goal of uniform heat distribution can be reduced.

[0120] Furthermore, by disposing the fans 103 adjacent to multiple sidewalls, the display 1 can have better heat uniformity in more second orientations SO. By disposing the fans 103 and the corresponding ventilation holes 106 adjacent to multiple sidewalls of the display 1, the display 1 can also have better heat dissipation in multiple second orientations SO.

Any person with ordinary knowledge in the technical field to which the present invention pertains may make some modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be determined by the scope of the appended patent application.
