Detailed Description

The present application will be described in further detail with reference to the following drawings and examples. It is to be noted that the following examples are only illustrative of the present application, and do not limit the scope of the present application. Likewise, the following examples are only some examples and not all examples of the present application, and all other examples obtained by a person of ordinary skill in the art without any inventive work are within the scope of the present application.

Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.

Referring to fig. 1, fig. 1 is a schematic exploded view of a monitoring device 100 according to some embodiments of the present application, the monitoring device 100 generally including a housing assembly 10 and a display screen assembly 20. The housing assembly 10 forms an accommodating space 101, and the accommodating space 101 is configured to accommodate a parameter module, a power module, and a circuit board of the monitoring device 100. Specifically, the housing assembly 10 may be a box-shaped structure with an opening at one end, that is, the display screen assembly 20 is covered on the opening of the housing assembly 10, so that the display screen assembly 20 can display images to the outside through the opening of the housing assembly 10. In this embodiment, a window is disposed on a side of the housing assembly 10 close to the display screen assembly 20, and the display screen assembly 20 is mounted on the window of the housing assembly 10. The display screen assembly 20 and the housing assembly 10 together enclose the accommodating space 101.

Referring to fig. 2 to 4, fig. 2 is a schematic structural diagram of a display screen assembly 20 in the embodiment of fig. 1, fig. 3 is a schematic structural diagram of the display screen assembly 20 in the embodiment of fig. 2, and fig. 4 is a schematic structural diagram of a cross section of the display screen assembly in the embodiment of fig. 2 along the direction a-a, where the display screen assembly 20 may generally include a cover plate 21, a touch panel 22, and a display panel 23 that are stacked. The cover plate 21 may be made of a transparent material, for example, the cover plate 21 may be a transparent glass cover plate or a transparent resin cover plate. The touch panel 22 may be used for a user to input a control instruction to implement human-computer interaction, for example, when the touch panel 22 responds to a gesture touch of the user, the display panel 23 may display a menu switch, a pop-up switch of a parameter setting window, or the like, correspondingly. The display panel 23 can also be used to display the data information monitored by the monitoring device 100 and the processed image information, so that the user can more intuitively know the monitored information. The touch panel 22 is generally a light-permeable panel, and not only can be used for responding to user operations, but also can enable image information displayed by the display panel 23 to sequentially pass through the touch panel 22 and the cover plate 21 to be viewed by a user.

It should be noted that fig. 2-4 illustrate X, Y and Z directions of the display screen assembly 20, mainly to illustrate XY, XZ and YZ planes for convenience of description. All directional indications (such as up, down, left, right, front, and rear … …) in the embodiments of the present application are only used to explain the relative positional relationship between the components, the movement, and the like in a specific posture (as shown in the drawings), and if the specific posture is changed, the directional indication is changed accordingly. The XY plane is a plane substantially parallel to the display surface of the display panel assembly 20, and the Z direction is a thickness direction of the display panel assembly 20, i.e. the Z direction can be regarded as a stacking direction of the display panel assembly 20.

It will be appreciated that when the orthographic projection of the screen assembly 20 onto the XY plane is generally rectangular, the X direction may be considered to be the direction of extension of the shorter side of the orthographic projection of the screen assembly 20 and the Y direction may be considered to be the direction of extension of the longer side of the orthographic projection of the screen assembly 20. Of course, in other embodiments, the X-direction may be considered to be the height direction of the monitoring device 100 when the monitoring device 100 is normally positioned with the user facing the display screen assembly 20.

Specifically, the touch panel 22 is disposed between the cover 21 and the display panel 23, that is, the touch panel 22 is disposed on the light exit surface of the display panel 23 and configured to sense a touch action of a user. The cover plate 21 and the housing assembly 10 jointly enclose the accommodating space 101, and the touch panel 22 and the display panel 23 are accommodated in the accommodating space 101. The touch panel 22 is attached to an inner surface of the cover plate 21 (i.e., a surface of the cover plate 21 close to the accommodating space 101), and the display panel 23 is attached to a side of the touch panel 22 away from the cover plate 21.

Further, the orthographic projection of the display panel 23 on the touch panel 22 covers a part of the touch panel 22, and the orthographic projection of the touch panel 22 on the cover 21 covers a part of the cover 21. In other words, the orthographic projection of the cover 21 on the touch panel 22 completely covers the touch panel 22, and the orthographic projection of the touch panel 22 on the display panel 23 completely covers the display panel 23. That is, the projection area of the cover 21 projected on the XY plane is not smaller than the projection area of the touch panel 22 projected on the XY plane, and the projection area of the touch panel 22 projected on the XY plane is not smaller than the projection area of the display panel 23 projected on the XY plane. It can be understood that, in the stacking direction of the cover plate 21, the touch panel 22 and the display panel 23, the areas of the cover plate 21, the touch panel 22 and the display panel 23 are sequentially reduced, the cover plate 21 covers the touch panel 22, and the touch panel 22 covers the display panel 23.

In this embodiment, the display panel assembly 20 may further include a circuit board 24, and the circuit board 24 is electrically connected to the touch panel 22. The circuit board 24 may be a flexible circuit board, one end of the circuit board 24 is connected to the touch panel 22, and the other end of the circuit board 24 is folded to a side of the display panel 23 away from the touch panel 22 for connecting to a main control board.

It is understood that the housing space 101 of the housing assembly 10 can accommodate therein a main control board, a processor, etc. of the monitoring device 100. The touch panel 22 is connected to the main control board through the circuit board 24, so that the main control board can receive an instruction input by the touch panel 22 and transmit the instruction to the processor, so that the processor can control the display panel 23 to perform corresponding display. In addition, the main control board may also be connected to the display panel 23, so that the main control board may respond to the instruction of the processor to control the display panel 23 to perform corresponding display.

The cover 21 may generally include a first light-transmitting region 211, a second light-transmitting region 212, and a non-light-transmitting region 213, the first light-transmitting region 211 being adjacent to the non-light-transmitting region 213, and the second light-transmitting region 212 being adjacent to the non-light-transmitting region 213. The first light-transmitting region 211 and the second light-transmitting region 212 are spaced apart from each other.

It is to be understood that the "first transparent region", "second transparent region" and "transparent region" are generally transparent regions on the cover plate, and the "non-transparent region" is generally opaque regions on the cover plate. For example, in some embodiments, the cover plate is made of a transparent material (e.g., glass, etc.), and the opaque material (e.g., ink, etc.) is printed on a portion of the surface of the cover plate to form the opaque region, and the region of the cover plate other than the opaque region is the transparent region.

In one embodiment, the first light-transmitting region 211 may be provided with one or more. When the first light-transmitting regions 211 are provided in plurality, the first light-transmitting regions 211 are disposed at intervals. It is understood that the meaning of "a plurality" is at least two, e.g., two, three, etc., unless specifically limited otherwise. The non-transmissive region 213 surrounds the one or more first transmissive regions 211.

The touch panel 22 may generally include a first sensing region 221, a second sensing region 222 and a non-sensing region 223, wherein the first sensing region 221 is adjacent to the non-sensing region 223, and the second sensing region 222 is adjacent to the non-sensing region 223. Wherein the first sensing region 221 and the second sensing region 222 are disposed at an interval. It is understood that the regions such as the "first sensing region", the "second sensing region" and the "sensing region" generally refer to a region of the touch panel where a user touch action can be sensed, and the "non-sensing region" generally refers to a region of the touch panel where a user touch action cannot be sensed.

In an embodiment, one or more first sensing regions 221 may be provided. When the first sensing region 221 is provided in plurality, the plurality of first sensing regions 221 are disposed at intervals. Wherein the non-sensing area 223 surrounds the one or more first sensing areas 221.

The display panel 23 generally includes a display area 231 and a non-display area 233 adjacent to the display area 231, and the display area 231 can be used for displaying the picture of the monitoring device 100.

Further, the second transparent region 212, the second sensing region 222, and the display region 231 are disposed correspondingly, the non-transparent region 213, the non-sensing region 223, and the non-display region 233 are disposed correspondingly, and the first transparent region 211 and the first sensing region 221 are disposed correspondingly. That is, in the Z direction, the second light-transmitting region 212, the second sensing region 222, and the display region 231 are sequentially stacked, the non-light-transmitting region 213, the non-sensing region 223, and the non-display region 233 are sequentially stacked, and the first light-transmitting region 211 and the first sensing region 221 are stacked. The projection of the first light-transmitting area 211 on the touch panel 22 is located in the first sensing area 221, that is, the light can pass through the first light-transmitting area 211 via the first sensing area 221. The user can see the picture displayed in the display area 231 through the second light-transmitting area 212. When the second sensing area 222 responds to the gesture touch of the user in the second light-transmitting area 212, the display area 231 may correspondingly display the display contents such as menu switching or popup switching of the parameter setting window. The display area 231 can also be used to display data information monitored by the monitoring device 100 and processed image information so that the user can more intuitively understand the monitored information.

It should be noted that the terms "first" and "second" in the present application are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature.

In one embodiment, the cover 21 may further be printed with at least one key identification 214. When the key mark 214 is provided in plural, plural key marks 214 are provided at intervals. The key marks 214 and the first light-transmitting areas 211 are arranged in a one-to-one correspondence manner. Specifically, each first light-transmitting area 211 surrounds at least a portion of the outer periphery of the key mark 214 corresponding to the first light-transmitting area 211.

In an embodiment, when the first light-transmitting area 211 surrounds a portion of the outer periphery of the key mark 214, the non-light-transmitting area 213 surrounds the first light-transmitting area 211 and the key mark 214, and the non-light-transmitting area 213 and the outer periphery surrounded by the first light-transmitting area 211 and the key mark 214 are adjacent to each other.

Further, the key identifier 214 and the first sensing area 221 are stacked, that is, the cover 21 covers the touch panel 22, so that the user touch action occurring on the key identifier 214 is sensed by the touch panel 22. In other words, when the first sensing region 221 responds to the gesture touch of the user on the key identifier 214, the display region 231 may correspondingly display the display contents such as menu switching, or pop-up switching of the parameter setting window.

As shown in fig. 5, the key identification 214 is substantially rectangular or rectangular-like. The shape of the first light-transmitting area 211 is adapted to the shape of the key indicator 214, that is, the first light-transmitting area 211 is substantially rectangular or rectangular-like and surrounds the outer periphery of the key indicator 214. It should be understood that the key indicator 214 may also be one or more of a triangle, a circle, an ellipse, a polygon, etc., and the first light-transmitting region 211 may also be one or more of a triangle, a circle, an ellipse, a polygon, etc.

In the present embodiment, the shape of the first light-transmitting area 211 is adapted to the shape of the key mark 214. In other embodiments, the shape of the first light-transmitting region 211 and the shape of the key indicator 214 may not be adapted. That is, the present embodiment does not specifically limit the shapes of the key identifier 214 and the first light-transmitting area 211. It is understood that, no matter what shape the key indicator 214 and the first light-transmitting area 211 are, the first light-transmitting area 211 in this embodiment surrounds the outer periphery of the key indicator 214.

Referring to fig. 8, fig. 8 is a schematic layout view of a cover plate 21 according to another embodiment of the present application.

The shapes of the first light-transmitting areas 211 may be the same or different, and the shapes of the key marks 214 may be the same or different. Alternatively, at least some of the first light-transmitting regions 211 in the plurality of first light-transmitting regions 211 have the same shape, and at least some of the key identifiers 214 in the plurality of key identifiers 214 have the same shape. Still alternatively, at least some of the first light-transmitting regions 211 among the plurality of first light-transmitting regions 211 have different shapes, and at least some of the key marks 214 among the plurality of key marks 214 have different shapes.

Specifically, the shapes of the key identifier 214a and the key identifier 214b are substantially the same, the shapes of the key identifier 214c and the key identifier 214d are substantially the same, and the shapes of the key identifier 214a and the key identifier 214b are different from the shapes of the key identifier 214c and the key identifier 214 d. The first light transmission region 211a and the first light transmission region 211c have substantially the same shape, and the first light transmission region 211b and the first light transmission region 211d have different shapes. The first light-transmitting area 211a surrounds a portion of the outer periphery of the key mark 214a, the first light-transmitting area 211b surrounds a portion of the outer periphery of the key mark 214b, the first light-transmitting area 211c surrounds a portion of the outer periphery of the key mark 214c, and the first light-transmitting area 211d surrounds a portion of the outer periphery of the key mark 214 d.

Further, at least a portion of the first light-transmitting area 211 of the plurality of first light-transmitting areas 211 surrounds a portion of an outer circumference of the corresponding key mark 214, or at least a portion of the first light-transmitting area 211 of the plurality of first light-transmitting areas 211 surrounds a portion of an outer circumference of the corresponding key mark 214.

It is understood that, regarding the corresponding relationship between the first light-transmitting area 211 and the key mark 214, the embodiment is only exemplified above, and other modifications by those skilled in the art according to the embodiment should be understood as being within the protection scope of the embodiment.

In this embodiment, each key identifier 214 may correspond to a corresponding function key of the monitoring device 100 to indicate that a corresponding function operation can be implemented through the key identifier 214. For example, a key mark 214 may have a power key pattern, a key mark 214 may have an ecg key pattern, a key mark 214 may have a blood pressure key pattern, a key mark 214 may have an oximetry key pattern, a key mark 214 may have a body temperature key pattern, and a key mark 214 may have a pulse rate key pattern. It should be understood that the present embodiment only exemplifies the above-mentioned key mark 214 pattern, and the key mark 214 pattern may be other types, which are not listed here.

Light can be transmitted through the first light-transmitting area 211 to indicate the execution status of the function key corresponding to the key indicator 214. For example, when light passes through the first light-transmitting area 211 corresponding to the key mark 214 with the power key pattern, it indicates that the power key function is in an on state, i.e., the monitoring device 100 is in an on state. For another example, when the first light-transmitting area 211 corresponding to the key mark 214 with the blood pressure key pattern has light transmitted therethrough, it indicates that the blood pressure detecting function is being performed.

The key mark 214 may be formed on the cover plate 21 by silk-screen printing or spraying.

Referring to fig. 9, fig. 9 is a schematic view of a light path of the first light-transmitting area 211 according to some embodiments of the present disclosure, wherein the display panel assembly 20 may further include a light assembly 25.

Specifically, the optical element 25 is disposed on a side of the touch panel 22 close to the display panel 23, that is, the optical element 25 is disposed on a side of the touch panel 22 away from the cover 21. The optical component 25 and the touch panel 22 are disposed at an interval in the Z direction. The light assembly 25 is configured to emit light outwards, so that the light can be emitted through the first transmissive region 211. The light emitted by the light assembly 25 sequentially passes through the first sensing region 221 and the first light-transmitting region 211 along the Z-direction and then is emitted, and the user can see the light emitted by the light assembly 25 through the first light-transmitting region 211.

Further, the light assembly 25 may generally include a light plate 251 and a light source 252, the light plate 251 and the touch panel 22 are spaced apart from each other and used for mounting the light assembly 25, and the light source 252 is mounted on the light plate 251 and is disposed on a side of the light plate 251 close to the touch panel 22 for emitting light outwards. The light source 252 may be provided in one or more, and when the light source 252 is provided in plural, the plural light sources 252 are provided at intervals. In the present embodiment, the light sources 252 and the first light-transmitting regions 211 are disposed in a one-to-one correspondence, so that the light emitted from each light source 252 can be emitted along the corresponding first light-transmitting region 211. In other words, the key identifier 214, the first sensing region 221, and the light source 252 are stacked in sequence, and light emitted from the light source 252 sequentially passes through the first sensing region 221 and the first light-transmitting region 211 along the Z direction and then is emitted. It is understood that the light source 252 may be a light-emitting diode (LED) lamp.

In the embodiment, the light assembly 25 and the display panel 23 are located in the order of the touch panel 22 away from the cover 21, and the light panel 251 and the display panel 23 are arranged side by side. In other words, the light panel 251/the light source 252 and the display panel 23 are disposed substantially side by side in the orthographic projection of the display panel 23 onto the plane (XY plane) on which the display panel 23 is projected. Preferably, the light panel 251/light source 252 and the orthographic projection of the display panel 23 onto the XY plane are arranged side by side substantially along the X direction.

It is understood that the light source 252 is electrically connected to the light panel 251, the light panel 251 is electrically connected to a main control board in the monitoring device 100, and the main control board can control the light source 252 to be turned on or off according to the received instruction and through the light panel 251. The main control board may control a single light source 252 to be turned on, or the main control board may control some or all of the light sources 252 to be turned on, which may be set by a person skilled in the art according to actual needs, and is not described herein again.

In this embodiment, the optical component 25 is disposed in the offset region between the edges of the touch panel 22 and the display panel 23, so as to reasonably utilize the layout space, which is beneficial to the overall structural layout of the display panel component 20.

In the research of the applicant, it is found that the front projection portion of the first sensing region 221 and the first light-transmitting region 211 projected onto the plane of the display panel 23 covers the non-display region 233 of the display panel 23, so that the light emitted from the light assembly 25 passes through a portion of the first sensing region 221 and a portion of the first light-transmitting region 211, and further the light-transmitting pattern displayed on the first light-transmitting region 211 is incomplete.

Based on this, the applicant further develops another display panel assembly 20 to solve the technical problem that the light-transmissive pattern displayed on the first light-transmissive region 211 is incomplete.

Referring to fig. 10, fig. 10 is a schematic cross-sectional view of a display panel assembly 20 according to another embodiment of the present application. In the present embodiment, the first sensing region 221 of the touch panel 22 is completely protruded from the edge of the display panel 23, and the first light-transmitting region 211 is completely protruded from the edge of the display panel 23. In other words, the orthographic projection of the first sensing region 221 onto the XY plane and the orthographic projection of the display panel 23 onto the XY plane are arranged side by side without an overlapping region. The orthographic projection of the first light-transmitting region 211 on the XY plane and the orthographic projection of the display panel 23 on the XY plane are arranged side by side without an overlapping area. The light assembly 25, the first sensing region 221 and the first light-transmitting region 211 are sequentially stacked, wherein the light assembly 25 and the first sensing region 221 are spaced apart.

Further, the light emitted from the light source 252 almost completely covers the first sensing region 221 and the first light-transmitting region 211, so that the first light-transmitting region 211 can show a complete light-transmitting pattern. It is to be understood that technical features not described in detail with respect to the display screen assembly 20 may be referred to the foregoing embodiments.

Referring to fig. 11 and 12 in combination, fig. 11 is a schematic exploded view of a display panel assembly 20 according to another embodiment of the present application, and fig. 12 is a schematic cross-sectional view of the display panel assembly 20 according to the embodiment of fig. 11. The display screen assembly 20 may further include a light assembly 25 and a light guide 26, among other things.

Specifically, the light assembly 25 is disposed on a side of the touch panel 22 close to the display panel 23, and light emitted from the light assembly 25 is emitted through the light guide 26, the first sensing area 221, and the first light transmission area 211. I.e., the light emitted by the light assembly 25 is visible to the user through the first light transmitting region 211.

The light guide 26 is disposed on a side of the touch panel 22 close to the display panel 23, or the light guide 26 is disposed between the touch panel 22 and the display panel 23. The orthographic projection of the light guide 26 projected on the plane of the touch panel 22 completely covers the first sensing area 221, or the orthographic projection of the light guide 26 projected on the plane of the cover plate 21 completely covers the first light-transmitting area 211. The light emitted from the light assembly 25 firstly enters from the light incident surface of the light guide 26, is homogenized by the light guide 26, then exits from the light exiting surface of the light guide 26 to the first sensing region 221, and then irradiates to the first light transmission region 211 through the first sensing region 221 and exits from the first light transmission region 211.

In the embodiment, the light guide 26 is substantially a sheet structure, and the light guide 26 may be attached to one side of the touch panel 22 close to the display panel 23, may be attached to one side of the display panel 23 close to the touch panel 22, and may be attached to the touch panel 22 and the display panel 23 respectively at two opposite sides of the light guide 26. The light guide 26 may generally include a light incident surface and a light emitting surface connected in a bent manner.
