The transparent cover plate 310 may adopt a common transparent cover plate 310, which is used for protecting the display screen 320, so as to avoid damage of the display screen 320 caused by collision of external force, and can play a role in dust prevention; the light-transmitting cover plate 310 with the touch function can also be adopted, so that the electronic device 10 has the touch function, and the use is more convenient for users. Therefore, the specific material of the transparent cover plate 310 is not particularly limited in the present application.
In addition, the display 320 may be a flexible display or a rigid display. For example, the display 320 may be an organic light-emitting diode (OLED) display, an active-matrixorganic light-emitting diode (AMOLED) display, a mini-led (mini organic light-emitting diode) display, a micro-led (micro organic light-emitting diode) display, a micro-organic led (micro organic light-emitting diode) display, a quantum dot led (quantum dot light emitting diode, QLED) display, or a liquid crystal display (liquid crystal display, LCD) or the like.
When the electronic device 10 is in operation, the electronic device 10 can be interconnected with a mobile phone to display information in the mobile phone, such as a micro message, a short message, a call, etc., while displaying time and date via the display module 300. In addition, some electronic devices 10 also have a function of monitoring information of the user's body, for example, monitoring heart rate, blood pressure, etc., and these information can be displayed by the display module 300.
However, since the time and date displayed by the display module 300 can only display digital information on the display surface of the display module 300, the stereoscopic impression of the hands and dial of the mechanical watch cannot be displayed, and the display effect of the electronic device 10 cannot be accepted for the user who is used to wear the mechanical watch, thereby reducing the user experience.
In the related art, in order to solve the above-mentioned problems, a small display screen is embedded in the dial of some mechanical watches to display some information on the mobile phone. However, since the display screen is small, contents that can be displayed are limited, and thus functions of the intelligent system may be limited. In addition, when the watch is manufactured, a mechanical pointer and a dial are needed, a display screen is integrated on the dial, and an intelligent system is arranged, so that on one hand, the design difficulty is increased, and on the other hand, the production cost is increased.
Referring to fig. 3 and fig. 4, fig. 3 is a block diagram of a display module 300 of the electronic device 10 according to an embodiment of the application, and fig. 4 is a block diagram of a control system of the display module 300 shown in fig. 3. The electronic device 10 includes the wristband 100 and the case 200 described above, and further includes a display module 300 shown in fig. 3. The display module 300 includes a transparent cover 310, a first display 330, a second display 340, and a driving circuit 350.
Specifically, the first display screen 330 and the second display screen 340 are stacked and arranged at intervals, and a side of the second display screen 340 facing the first display screen 330 is a display side of the second display screen 340, that is, a surface of the second display screen 340 facing the first display screen 330 is an image display surface of the second display screen 340; the side of the first display screen 330 away from the second display screen 340 is the display side of the first display screen 330, i.e. the surface of the first display screen 330 away from the second display screen 340 is the image display surface of the first display screen 330.
The first display 330 is used for displaying a pointer image of the mechanical watch, and the second display 340 is used for displaying a dial plate of the mechanical watch and an intelligent system image. The light-transmitting cover 310 is disposed on the display side of the first display 330. The driving circuit 350 is electrically connected to the first display 330, and the driving circuit 350 is electrically connected to the second display 340, and the driving circuit 350 is configured to drive the first display 330 to display the pointer and drive the second display 340 to display the dial.
In this way, the electronic device 10 drives the first display 330 to display the pointer and the second display 340 to display the dial simultaneously through the driving circuit 350, and the first display 330 and the second display 340 are spaced apart, i.e. have a gap therebetween. Accordingly, the pointer image displayed on the first display screen 330 and the dial image displayed on the second display screen 340 can display the stereoscopic impression of the mechanical wristwatch.
Meanwhile, the second display screen 340 is further used for displaying an image of the intelligent system, so as to display information of other devices (such as mobile phones) interconnected and intercommunicated with the electronic device 10, thereby realizing image display of the intelligent system. Therefore, the display module 300 can display the mechanical pointer type visual effect and simultaneously display the image of the intelligent system, so that the electronic device 10 can display the stereoscopic effect of the mechanical pointer while realizing the intelligence, thereby being beneficial to improving the user experience.
It will be appreciated that, since the first display screen 330 and the second display screen 340 need to display the image content at the same time and cooperate, the images displayed on the first display screen 330 and the second display screen 340 need to be aligned at the pixel level, so as to avoid the occurrence of jaggies or moire patterns on the images caused by the pixel misalignment between the first display screen 330 and the second display screen 340, thereby ensuring the display effect of the images.
It should be noted that the pixel level alignment means that the pixel points of the first display screen 330 and the pixel points of the second display screen 340 are overlapped along the thickness direction of the display module 300. The overlapping may be complete or substantially overlapping, that is, the pixels of the first display screen 330 overlap with the corresponding pixels on the second display screen 340, for example, 95% overlap, and only the portion not overlapping by more than 5%.
In some embodiments, a gap L may be disposed between the first display screen 330 and the second display screen 340, so that the first display screen and the second display screen are disposed at a distance, and light transmission can be achieved. Alternatively, referring to fig. 5, fig. 5 is a block diagram of another display module 300 according to an embodiment of the present application, the display module 300 may further include a transparent substrate 360, the transparent substrate 360 is disposed between the first display screen 330 and the second display screen 340, one surface of the transparent substrate 360 is fixed to the first display screen 330 in a bonding manner, and the other surface of the transparent substrate 360 is fixed to the second display screen 340 in a bonding manner. In this way, on the one hand, the first display screen 330 and the second display screen 340 can be arranged at intervals through the transparent substrate 360; on the other hand, the transparent substrate 360 can form a support between the first display screen 330 and the second display screen 340, which is beneficial to improving the overall support strength of the display module 300. The transparent substrate 360 may be made of a transparent material having high light transmittance, for example, optical glass or acryl, and the material of the transparent substrate 360 is not particularly limited in the present application.
In addition, the size of the gap L between the first display screen 330 and the second display screen 340 may be determined according to the distance between the hands and the dial of the mechanical watch. Illustratively, the distance between the hands and the dial of the mechanical watch is generally 1-2 mm, and thus, the gap L between the first display screen 330 and the second display screen 340 provided by the embodiment of the present application may be 1-2 mm. Specifically, it may be 1mm, 1.3mm, 1.5mm, 1.8mm, 2mm or the like. That is, the thickness H of the transparent substrate 360 may be 1 to 2mm. Specifically, it may be 1mm, 1.3mm, 1.5mm, 1.8mm, 2mm or the like. Therefore, the present application is not particularly limited thereto.
In addition, since the second display screen 340 needs to display an image through the first display screen 330, the first display screen 330 needs to have light transmittance so that the image of the second display screen 340 can pass through the first display screen 330 for the user to view. Specifically, referring to fig. 6, fig. 6 is a front view of the display module 300 provided in fig. 3, the first display screen 330 may include a first display area 330a, where the outline of the first display area 330a forms the pointer shape of the mechanical watch, and the area outside the first display area 330a is a first transparent area 330b. The image displayed on the second display screen 340 is displayed through the first light-transmitting area 330b, so that a user can see a mechanical watch display effect with a stereoscopic effect formed by the watch hand displayed on the first display screen 330 and the dial displayed on the second display screen 340.
In some examples, the first display area 330a may be displayed in a different color, for example, the first display area 330a may be displayed in black, that is, a region where black is displayed on the first display screen 330 forms a pointer, and the other regions are all transparent. The color of the first display area 330a may also be blue, red, gray, white, yellow, etc., which is not particularly limited in the present application.
In addition, since the pointer of the watch is thin, the area occupied on the display surface of the first display screen 330 is small, which is generally not more than 2% of the whole display surface of the first display screen 330, so that the pointer formed by the first display area 330a does not cause large-area shielding to the image displayed on the second display screen 340, i.e. the user is not influenced to view the image displayed on the second display screen 340.
In addition, the hands may include only an hour hand and a minute hand. Thus, the user can accurately know the current time through the hour hand and the minute hand. Also, the hour and minute hand move more slowly in the displayed image, without affecting the user's view of the image displayed on the second display screen 340.
Alternatively, the hand may include an hour hand, a minute hand, and a second hand. Therefore, the stereoscopic effect of the mechanical watch can be better displayed, and good use experience can be obtained for a part of users who are used to using the mechanical watch.
The driving circuit 350 is configured to simultaneously control the first display screen 330 and the second display screen 340 to display images, so as to realize the collaborative display of the first display screen 330 and the second display screen 340. In some embodiments, the driving circuit 350 may be integrated on a chip, i.e. form a driving chip, and the driving chip controls the display images of the first display screen 330 and the second display screen 340 simultaneously. Alternatively, the driving circuits 350 may be integrated on two chips, that is, two driving chips are formed, the two driving chips control the first display screen 330 and the second display screen 340 respectively, and the two driving chips are controlled and driven by the same controller, so as to realize the collaborative display of the first display screen 330 and the second display screen 340. Therefore, the present application is not particularly limited to the specific configuration of the driving circuit 350.
Based on this, since the second display screen 340 needs to display an image through the first light-transmitting region 330b of the first display screen 330, the first display screen 330 needs to have a better light-transmitting performance. So that the display image of the second display screen 340 can be displayed in a state where the first display screen 330 displays the pointer or does not display the pointer (i.e., the first display screen 330 is in a screen-off state where no image is displayed).
In some embodiments, the first display screen 330 and the second display screen 340 may each use an LCD screen, and since the LCD screen needs a backlight, the first display screen 330 and the second display screen 340 may share a backlight, so that the first display screen 330 has light transmittance. Referring to fig. 7 and 8, fig. 7 is a block diagram of another display module 300 according to an embodiment of the application, and fig. 8 is a front view of a second display screen 340 in the display module 300 shown in fig. 7.
The first display 330 includes a first liquid crystal display panel 331, the second display 340 includes a second liquid crystal display panel 341 and a first backlight layer 342, and the first backlight layer 342 is disposed on a side of the second liquid crystal display panel 341 away from the first liquid crystal display panel 331. The vertical projection of the first display area 330a on the second liquid crystal display panel 341 forms a second light-transmitting area 341a, and an area (hatched portion in fig. 8) other than the second light-transmitting area 341a on the second liquid crystal display panel 341 is a second display area 341b.
Specifically, the first liquid crystal display panel 331 includes a first TFT (Thin Film Transistor ) layer 3311, a first liquid crystal layer 3312, a first filter 3313, and a first polarizer 3314, which are stacked in this order in a direction away from the second liquid crystal display panel 341. The second liquid crystal display panel 341 includes a second polarizer 3411, a second TFT layer 3412, a second liquid crystal layer 3413, and a second filter 3414, which are stacked in this order in a direction away from the first backlight layer 342.
Thus, the first liquid crystal display panel 331 and the second liquid crystal display panel 341 may share the same backlight source, i.e. the first backlight layer 342. And, the liquid crystal at the second light-transmitting area 341a on the second liquid crystal display panel 341 is in an all-on state, so that light can transmit through the second liquid crystal display panel 341 and be received by the first display area 330a of the first liquid crystal display panel 331, and the first display area 330a on the first liquid crystal display panel 331 displays different colors, namely, displays a pointer. Meanwhile, the liquid crystal of the first light-transmitting area 330b on the first liquid crystal display panel 331 is also in an all-on state, so that an image displayed by the second display area 341b on the second liquid crystal display panel 341 is displayed through the first light-transmitting area 330b of the first liquid crystal display panel 331.
In addition, the polarizer is not disposed on the side of the first lcd panel 331 close to the first lcd panel 331 and the side of the second lcd panel 341 close to the first lcd panel 331, so that the light emitted from the light emitting side of the second lcd panel 341 can be ensured to be directly incident on the first display area 330a of the first lcd panel 331, which is beneficial to improving the display effect.
Further, the first TFT layer 3311 may be provided on a separate support substrate. The first TFT layer 3311 may be directly disposed on the transparent substrate 360, so that the thickness of the entire display module 300 may be reduced, and the overall thickness of the electronic device 10 may be reduced, thereby reducing the thickness of the electronic device 10.
It should be noted that, the second TFT layer 3412 needs to have a separate supporting substrate to form a support, which is a conventional technical means of LCD panels, and thus will not be described in detail herein.
In other embodiments, the first display screen 330 may also be an ink screen, that is, the first display screen 330 includes a first ink display panel 332. Referring to fig. 9 and 10, fig. 9 is a block diagram of a display module 300 according to another embodiment of the application, and fig. 10 is a block diagram of a first ink display panel 332 in the display module 300 shown in fig. 9.
Specifically, the first ink display panel 332 includes an upper substrate 3321 (the upper surface thereof is the display surface of the first ink display panel 332), a lower substrate 3322, and a transparent capsule layer 3323 disposed between the upper substrate 3321 and the lower substrate 3322, wherein the transparent capsule layer 3323 includes a plurality of transparent capsules 3323a (i.e. electronic ink). Wherein, electrode films (not shown) are disposed on both the upper substrate 3321 and the lower substrate 3322. The transparent capsule 3323a has a liquid charge disposed therein, for example, positive charge to white and negative charge to black. When positive and negative voltages are applied to the first ink display panel 332, the distribution of the white charges and the black charges can be controlled by attraction and repulsion between the charges, so that a black or white picture is displayed on the first ink display panel 332 or a transparent state is displayed.
For example, when white charges are concentrated on the display side (side near the upper substrate 3321) of the first ink display panel 332, the first ink display panel 332 can display a white image as shown by the transparent capsule 3323a on the left side in fig. 10. When black charges are concentrated on the display side of the first ink display panel 332, the first ink display panel 332 is able to display a black image, as shown by the transparent capsule 3323a on the right side in fig. 10. When the white charges and the black charges are distributed in the transparent capsule layer 3323 in a direction parallel to the first ink display panel 332, the white charges are distributed on the left side and the black charges are distributed on the right side as shown in fig. 10, that is, neither the white charges nor the black charges are concentrated on the display side of the first ink display panel 332, thereby making the first ink display panel 332 in a transparent state.
In this way, only the first display area 330a on the first ink display panel 332 is required to display white or black, and the first transparent area 330b on the first ink display panel 332 is transparent, so that the first ink display panel 332 can display the pointer of the mechanical watch. And, the display image of the second display screen 340 can be displayed through the first light-transmitting region 330b of the first ink display panel 332.
In addition, since the ink screen does not need an additional light source, the ink screen has the advantage of saving power consumption, when the ink screen is adopted by the first display screen 330, the ink screen can be always highlighted, so that a user does not need to wake up the screen when looking over time, and the use experience of the mechanical watch is further reflected, so that the use experience of the user is improved.
Based on this, the second display screen 340 may employ an LCD screen, an OLED screen, or an ink screen while the first display screen 330 employs an ink screen.
For example, with continued reference to fig. 9 and 10, when the second display screen 340 employs an LCD screen, the second display screen 340 may include a third liquid crystal display panel 343 and a second backlight layer 344. The second backlight layer 344 is disposed on a side of the third liquid crystal display panel 343 away from the first ink display panel 332. Since the first ink display panel 332 has a self-luminous function, a light-transmitting region does not need to be provided on the third liquid crystal display panel 343. I.e. the second display screen 340 may display images using a conventional LCD screen.
Alternatively, the second display screen 340 may also employ an OLED screen or a water-ink screen. Referring to fig. 11 and 12, fig. 11 is a structural diagram of an OLED screen used for the second display screen 340 in the display module 300 provided in fig. 9, and fig. 12 is a structural diagram of an ink screen used for the second display screen 340 in the display module 300 provided in fig. 9.
The second display screen 340 may include a first OLED display panel 345 or a second ink display panel 346. Because the OLED screen or the ink screen has self-luminescence, the power consumption is saved. Therefore, the mechanical dial displayed on the second display screen 340 may be set to be normally bright, and displayed in cooperation with the pointer displayed on the first ink display panel 332, so that the image of the mechanical watch can be normally bright on the display module 300. In this way, when the user does not wake up the displayed image of the intelligent system, the image displayed by the display module 300 makes the electronic device 10 be equal to a mechanical table, so as to further improve the user experience.
Of course, the mechanical watch hands and dial images displayed on the first display screen 330 and the second display screen 340 may be set to be not normally displayed in a bright state, i.e. when the electronic device 10 is turned off, the display module 300 is completely in the off-screen state (i.e. black screen), so that the power consumption can be further saved, and the duration of the electronic device 10 can be prolonged.
Or, whether the pointer and the dial of the mechanical watch are always bright or not can be selected by the user, namely, the user can adjust whether the pointer and the dial of the mechanical watch are always bright or not through the setting function of the intelligent system, so that the user can select the mechanical watch according to personal use habits. Therefore, the present application is not particularly limited thereto.
In still other embodiments, the first display screen 330 may also select an OLED transparent screen. I.e. the first display screen 330 may comprise an OLED transparent display panel 333. Referring to fig. 13, fig. 13 is a block diagram of a display module 300 according to another embodiment of the application.
Specifically, the OLED transparent display panel 333 may include an upper transparent glass cover plate 3331 and a lower transparent glass cover plate 3332, and a light emitting layer 3333 disposed between the upper transparent glass cover plate 3331 and the lower transparent glass cover plate 3332. The light emitting layer 3333 has a transparent sub-pixel added thereto in addition to the original red, green and blue (i.e., RGB sub-pixels), which is uniformly distributed on the light emitting layer 3333, and since the transparent sub-pixel itself does not emit light, and the transparent sub-pixel is made of a highly transparent material. When numerous transparent sub-pixels are uniformly distributed on the light emitting layer 3333, the OLED transparent display panel 333 can have a certain light transmittance. And when the original RGB sub-pixels do not emit light, the OLED transparent display panel 333 can exhibit a completely transparent effect.
In this way, the RGB sub-pixels on the first display area 330a of the OLED transparent display panel 333 can emit light to display the pointer image. The RGB sub-pixels in the first transparent region 330b of the OLED transparent display panel 333 do not emit light, so that the first transparent region 330b is transparent, and the display pattern on the second display screen 340 can be displayed through the first transparent region 330b.
In addition, because the OLED transparent display panel 333 has the advantage of low power consumption, the pointer pattern displayed on the OLED transparent display panel 333 can be always displayed in a bright mode, that is, the screen is turned off, so that the user does not need to wake up the screen when viewing time, thereby being beneficial to further reflecting the use feeling of the mechanical watch and improving the use experience feeling of the user.
Based on this, while the first display screen 330 employs an OLED transparent screen, the second display screen 340 may employ an LCD screen, an OLED screen (here, a general OLED screen), or an ink screen.
For example, referring to fig. 13, the second display screen 340 may employ a conventional LCD screen, and since the OLED screen has a self-luminous property, it is not necessary to provide a light-transmitting region on the second display screen 340. That is, the LCD of the second display 340 may normally display images (dial of the mechanical watch, intelligent system images, etc.).
Alternatively, the second display screen 340 may also employ an OLED screen or a water-ink screen. Referring to fig. 14 and 15, fig. 14 is a structural diagram of an OLED screen used for the second display screen 340 in the display module 300 provided in fig. 13, and fig. 15 is a structural diagram of an ink screen used for the second display screen 340 in the display module 300 provided in fig. 13.
The second display screen 340 may include a second OLED display panel 347 or a third ink display panel 348. Because the OLED screen or the ink screen has self-luminescence, the power consumption is saved. Therefore, the mechanical dial displayed on the second display screen 340 may be set to be normally-bright, and be cooperatively displayed with the pointer displayed on the OLED transparent display panel 333, so that the image of the mechanical dial can be normally-bright displayed on the display module 300. In this way, when the user does not wake up the displayed image of the intelligent system, the image displayed by the display module 300 makes the electronic device 10 be equal to a mechanical table, so as to further improve the user experience.
Of course, the mechanical watch hands and dial images displayed on the first display screen 330 and the second display screen 340 may be set to be not normally displayed in a bright state, i.e. when the electronic device 10 is turned off, the display module 300 is completely in the off-screen state (i.e. black screen), so that the power consumption can be further saved, and the duration of the electronic device 10 can be prolonged.
Or, whether the pointer and the dial of the mechanical watch are always bright or not can be selected by the user, namely, the user can adjust whether the pointer and the dial of the mechanical watch are always bright or not through the setting function of the intelligent system, so that the user can select the mechanical watch according to personal use habits. Therefore, the present application is not particularly limited thereto.
In summary, the display module 300 provided in the embodiment of the present application can display the three-dimensional structure of the mechanical dial through the cooperative display of the first display screen 330 and the second display screen 340, so that the electronic device 10 has the intelligent system function and simultaneously displays the visual effect of the mechanical watch. Thereby facilitating a greater diversification of the functions of the electronic device 10 and enabling a better use experience for users that are accustomed to using mechanical watches.
In addition, in the display module 300 provided in the embodiment of the present application, the first display screen 330 and the second display screen 340 include, but are not limited to, the above-mentioned several screens. For example, the first display screen 330 may also employ other screens having better light transmission performance. The second display screen 340 has no requirement for light transmittance of the screen, and thus, more choices are available, i.e., the conventional display screen 320 can be used as the second display screen 340 according to the embodiment of the present application.
In the description of the present specification, a particular feature, structure, material, or characteristic may be combined in any suitable manner in one or more embodiments or examples.
The foregoing is merely illustrative of the present application, and the present application is not limited thereto, and any person skilled in the art will readily recognize that variations or substitutions are within the scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
