Description

Technical Field

[0001] This invention relates to the field of electronic equipment technology, and in particular to a display module and its control method and control device, as well as electronic equipment. Background Technology

[0002] With the rapid development of electronic technology, electronic devices are becoming increasingly powerful, leading to a surge in the number of electrical components they require. As the number of electrical components increases, improving the battery life of electronic devices has become a key focus.

[0003] To improve the battery life of electronic devices, the main technology used to improve battery life is to increase the capacity of the battery. However, increasing the battery capacity will inevitably increase the size of the battery, which will lead to the thickness of the electronic device, which is not conducive to the design of a thin and light electronic device. Summary of the Invention

[0004] This invention discloses a display module and its control method and device, as well as an electronic device, to solve the problem in related technologies where electronic devices increase battery capacity to enhance battery life, resulting in thicker electronic devices.

[0005] To solve the above-mentioned technical problems, the present invention is implemented as follows:

[0006] In a first aspect, this application discloses a display module, including a display body, a first photoelectric conversion element and a first control module, wherein the first photoelectric conversion element is disposed on the back side of the display body, and the display side of the display body is distributed opposite to the back side of the display body;

[0007] The first control module is connected to the display body. The first control module is used to control the display body to display at a corresponding resolution according to the ambient light intensity, so that the ambient light passes through the display body and is converted into photoelectric light by the first photoelectric conversion element.

[0008] Secondly, this application also discloses an electronic device, which includes the display module described in the first aspect.

[0009] Thirdly, this application also discloses a control method for a display module, wherein the display module is the display module described in the first aspect, and the control method includes:

[0010] Detect ambient light intensity;

[0011] The display body is controlled to display at a corresponding resolution based on the ambient light intensity, so that ambient light passes through the display body and is converted into photoelectric light by the first photoelectric converter.

[0012] Fourthly, this application also discloses a control device for a display module, wherein the display module is the display module described in the first aspect, and the control device includes:

[0013] The detection module is used to detect ambient light intensity;

[0014] The control module is used to control the display subject to display at a corresponding resolution according to the ambient light intensity, so that the ambient light passes through the display subject and is converted into photoelectric light by the first photoelectric converter.

[0015] The technical solution adopted in this invention can achieve the following technical effects:

[0016] The display module disclosed in this application comprises a display body, a first photoelectric converter, and a first control module. The first photoelectric converter is located on the back side of the display body, and the first control module is connected to the display body. The first control module can control the display body to display at a corresponding resolution according to the ambient light intensity, so that ambient light passes through the display body and is supplied to the first photoelectric converter for photoelectric conversion. The first photoelectric converter then converts solar energy into electrical energy through the photoelectric effect, thereby powering the display module or other components of the electronic device. This solves the problem of thicker electronic devices caused by increasing battery capacity to increase battery life in related technologies.

[0017] Since the first control module can control the display subject to display at the corresponding display resolution according to the ambient light intensity, and allow ambient light to pass through for photoelectric conversion by the first photoelectric conversion element, the display subject can display while allowing ambient light to pass through for photoelectric conversion by the first photoelectric conversion element.

[0037] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0038] The technical solutions disclosed in the various embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0039] Please refer to Figures 1 to 5 This invention discloses a display module, which includes a display body 100, a first photoelectric conversion element 200, and a first control module.

[0040] The display body 100 is a component of the display module used to display images, and the side of the display body 100 used to display images is the display side.

[0041] The display body is a component that allows light to pass through; optionally, the display body can be a transparent OLED component.

[0042] The first photoelectric conversion element 200 is a component capable of converting solar energy into electrical energy through the photoelectric effect. The first photoelectric conversion element 200 is disposed on the back side of the display body 100. It should be noted that the back side of the display body 100 is opposite to the display side of the display body 100.

[0043] The first control module is connected to the display body 100. The first control module is used to control the display body 100 to display at a corresponding resolution according to the ambient light intensity, so that the ambient light passes through the display body 100 and is converted by the first photoelectric conversion element 200. It should be noted that the ambient light intensity is inversely proportional to the display resolution, and the display resolution is inversely proportional to the amount of light transmitted by the display body 100.

[0044] It should be noted that when ambient light shines on the display body 100, in the display state, due to the blocking effect of the excitation state of the light-emitting layer 160 of the display body 100, only a small proportion of the ambient light can pass through the display body 100. When the display resolution is high, the illuminated area of ​​the light-emitting layer 160 of the display body 100 is larger, and the area where ambient light can pass through the display body 100 is smaller; when the resolution of the display body 100 is low, the illuminated area of ​​the light-emitting layer 160 of the display body 100 is relatively smaller, and the area where ambient light can pass through the display body 100 is larger.

[0045] In this paper, when the display resolution is high, the display body 100 has a stronger ability to block ambient light, and the ability of ambient light to pass through the display body 100 is weaker. When the display resolution is low, the display body 100 has a weaker ability to block ambient light, and the ability of ambient light to pass through the display body 100 is stronger.

[0046] When the ambient light intensity is high, the first control module can control the display resolution of the display body 100 to decrease, thereby allowing more ambient light to pass through the display body 100, which in turn allows more ambient light to be supplied to the first photoelectric conversion unit 200 for photoelectric conversion. When the ambient light intensity is low, the first control module can control the display resolution of the display body 100 to increase, thereby allowing less ambient light to pass through the display body 100, which in turn allows the display body 100 to display images better.

[0047] The first control module can control the display resolution of the display body 100 by controlling the deflection angle of the pixels 110 of the display body 100, or by controlling a portion of the display body 100 to light up while another portion is turned off. Of course, the display resolution of the display body 100 can also be controlled in other ways, which will not be described in detail here.

[0048] The display module disclosed in this application comprises a display body 100, a first photoelectric converter 200, and a first control module. The first photoelectric converter 200 is located on the back side of the display body 100, and the first control module is connected to the display body 100. The first control module can control the display body 100 to display at a corresponding resolution according to the ambient light intensity, so that ambient light passes through the display body 100 and is supplied to the first photoelectric converter 200 for photoelectric conversion. Thus, the first photoelectric converter 200 converts solar energy into electrical energy through the photoelectric effect, thereby powering the display module or other components of the electronic device. This solves the problem of thicker electronic devices caused by increasing battery capacity to increase battery life in related technologies.

[0049] Because the first control module can control the display body 100 to adjust the display resolution according to the ambient light intensity, and allow ambient light to pass through for photoelectric conversion by the first photoelectric converter 200, the display body 100 can simultaneously display and allow ambient light to pass through for photoelectric conversion by the first photoelectric converter 200. Since ambient light intensity is inversely proportional to display resolution, and display resolution is inversely proportional to the amount of light transmitted by the display body 100, when the ambient light intensity is high, the display resolution of the display body 100 can be reduced to allow more ambient light to pass through, thus providing more ambient light for photoelectric conversion by the first photoelectric converter 200. When the ambient light intensity is low, the photoelectric conversion performance of the first photoelectric converter 200 is low, so the display resolution of the display body 100 can be increased to allow less ambient light to pass through, resulting in better display performance. This makes the display module more rational in balancing display resolution and the photoelectric conversion performance of the first photoelectric converter 200.

[0050] In some embodiments, to change the display resolution, the first control module may control the deflection angle of the pixels 110 of the display body 100. However, to simplify the control of the display resolution of the display body 100 by the first control module, optionally, the display body 100 may include a plurality of pixels 110 arranged in an array, and the first control module may be connected to the plurality of pixels 110. When the display body 100 is in a first state, such as... Figure 1 As shown, the first control module can control a portion of the pixels 110 to be lit, while another portion is off, so that the area of ​​the light-transmitting region corresponding to the off-state pixels 110 is proportional to the amount of light transmitted by the display body 100, and the display resolution of the display body 100 is proportional to the area of ​​the light-transmitting region corresponding to the off-state pixels 110. The more off-state pixels 110 there are, the larger the corresponding light-transmitting region, resulting in a relatively lower display resolution and more light transmitted through the display body 100; conversely, the fewer off-state pixels 110 there are, the smaller the corresponding light-transmitting region, resulting in a relatively higher display resolution and less light transmitted through the display body 100.

[0051] The display module disclosed in this application uses a first control module to control a portion of the pixels 110 to be lit and another portion of the pixels 110 to be off, thereby changing the display resolution. This makes changing the display resolution relatively simple and easy to implement.

[0052] Optionally, when the display subject 100 is in the first state, the pixels 110 in the lit state can form multiple spaced lit areas, and the pixels 110 in the off state can form multiple spaced off areas. The display module disclosed in this application, by forming multiple spaced lit areas for the pixels 110 in the lit state and multiple spaced off areas for the pixels 110 in the off state, can avoid significant differences in the display performance of the display subject 100 caused by either all pixels 110 in a local area being displayed or all pixels 110 in a local area being undisplayed. This ensures the display performance of the display subject 100 as much as possible.

[0053] To ensure uniformity of display resolution, in one optional embodiment, the multiple pixels 110 can be distributed in multiple columns, and each pair of adjacent lit areas can have an off area, with the number of pixel columns contained in the off area between two adjacent lit areas being equal. The display module disclosed in this embodiment achieves relatively uniform display resolution by arranging the multiple pixels 110 in multiple columns, providing an off area for each pair of adjacent lit areas, and ensuring that the number of pixel columns contained in the off area between two adjacent lit areas is equal.

[0054] Of course, in some embodiments, the number of pixel columns contained in the off region between two adjacent lit regions may not be equal. Here, there is no specific limitation on the number of pixel columns contained in the off region between two adjacent lit regions.

[0055] In one optional embodiment, when the display body 100 is in the second state, the first control module can also be used to control multiple pixels 110 to be in a lit state. When the display body 100 is in the third state, the first control module can also be used to control multiple pixels 110 to be in a turned-off state.

[0056] It should be noted that when the display body 100 is in the second state, such as Figure 2 and Figure 3 As shown, when multiple pixels 110 are lit, only a small proportion of ambient light passes through the display body 100. When multiple pixels 110 are off, more ambient light can pass through the display body 100. In the second state, the ambient light intensity is weak (e.g., on a cloudy day, indoors, or at night). In this scenario, the efficiency of solar power generation is extremely low, and the user's display requirements are high; therefore, the display effect of the display body 100 can be prioritized. In the third state, the display body 100 is not working. At this state, the light transmittance of the display body 100 is good. Under conditions of high ambient light intensity, ambient light can pass through the display body 100 to enable the first photoelectric converter 200 to perform photoelectric conversion, thereby allowing the first photoelectric converter 200 to generate electricity more effectively.

[0057] The display module disclosed in this application allows the display body 100 to better display in the second state and better generate electricity in the third state by having a first control module control multiple pixels 110 to be lit in the second state and a first control module control multiple pixels 110 to be turned off in the third state.

[0058] To further enhance photoelectric conversion capability, the display module may optionally include a second photoelectric conversion component 300, which may be disposed on the display side of the display body 100 and may be a light-transmitting structural component.

[0059] The display module disclosed in this application can further improve the photoelectric conversion capability of the display module by setting a second photoelectric converter 300 on the display side of the display body 100. Moreover, when the display body 100 is displaying, the light emitted by the display body 100 will also pass through the second photoelectric converter 300, causing the second photoelectric converter 300 to generate electricity, which is equivalent to recovering and utilizing a portion of the electrical energy used by the display module for display.

[0060] Specifically, the first photoelectric conversion element 200 can be a silicon-based solar cell. Silicon-based solar cells have high photoelectric conversion efficiency, resulting in better power generation. The second photoelectric conversion element 300 can be a transparent organic solar cell. Transparent organic solar cells allow light to pass through, preventing light from being blocked from passing through the display body 100. Moreover, organic solar cells are flexible, allowing them to be better installed on the display body 100. Of course, the first photoelectric conversion element 200 and the second photoelectric conversion element 300 can also be other types of solar cells; no specific limitations are imposed here.

[0061] Optionally, the display body 100 may include a light-transmitting protective cover 120, which may be located on the display side of the display body 100. The second photoelectric conversion element 300 may be disposed on the inner side of the light-transmitting protective cover 120 and be attached to the inner surface of the light-transmitting protective cover 120. The light-transmitting protective cover 120 may protect the second photoelectric conversion element 300.

[0062] Optionally, the first control module can be connected to the second photoelectric converter 300. The first control module can be used to determine the ambient light intensity based on the internal current value of the second photoelectric converter 300. It should be noted that the internal current value of the second photoelectric converter 300 is directly proportional to the ambient light intensity. Specifically, during photoelectric conversion, an internal current is generated within the second photoelectric converter 300. The ambient light intensity is directly proportional to the internal current value of the second photoelectric converter 300; the greater the ambient light intensity, the greater the internal current value of the second photoelectric converter 300. Since there is a corresponding relationship between the internal current value of the second photoelectric converter 300 and the ambient light intensity, the ambient light intensity can be determined based on the internal current value of the second photoelectric converter 300.

[0063] The display module disclosed in this application determines the ambient light intensity based on the internal current value of the second photoelectric converter 300, so that the second photoelectric converter 300 can not only be used for power generation, but also indirectly detect the ambient light intensity, thereby giving the second photoelectric converter 300 the effect of having two uses in one device.

[0064] In some embodiments, in order to detect ambient light intensity, the display module may also be equipped with a dedicated light intensity sensor, such as a conventional photosensor.

[0065] To achieve a thinner and lighter display module, the first photoelectric conversion element 200 can optionally be attached to and fixed to the back surface of the display body 100. The display module disclosed in this application, by attaching and fixing the first photoelectric conversion element 200 to the back surface of the display body 100, avoids the need for a dedicated substrate layer for the first photoelectric conversion element 200, thereby simplifying the structure of the display module and contributing to its thinner and lighter design.

[0066] Optionally, the display body 100 may include a stacked anode layer 130, a hole injection layer 140, a hole transport layer 150, a light-emitting layer 160, an electron transport layer 170, an electron injection layer 180, and a cathode layer 190. When a voltage is applied to the display body 100, electrons from the cathode layer 190 and the anode layer 130 meet and combine in the light-emitting layer 160 to generate photons. The light-emitting layer 160 contains special organic materials that, together with the photons, become the three primary colors of red, green, and blue.

[0067] This application also discloses an electronic device, which includes the display module disclosed in the above embodiments. The electronic device disclosed in this application uses the display module from the above embodiments, enabling the first photoelectric converter 200 to convert solar energy into electrical energy through the photoelectric effect. This allows it to power the display module or other components of the electronic device, thereby solving the problem of thicker electronic devices caused by increasing battery capacity to enhance battery life in related technologies.

[0068] like Figure 6As shown, in some embodiments, the electronic device may further include an external power charging module 510, a battery 520, a power consumption module 530, and a power management module 540. Both the battery 520 and the power consumption module 530 can be connected to the power management module 540. When the display module includes a second photoelectric converter 300, the first photoelectric converter 200, the second photoelectric converter 300, and the external power charging module 510 can all be connected to the power management module 540 to supply power to either the battery 520 or the power consumption module 530, or simultaneously to either the battery 520 or the power consumption module 530. The power management module 540 can control whether the electronic device is powered by the display module or by the battery. Dynamic path management can dynamically adjust the charging current based on the input power capability and load current level, thereby ensuring that the charging time of the battery 520 is minimized while prioritizing the power consumption of the electronic device.

[0069] like Figure 7 As shown, in the specific implementation process, the display module can default to the second state. The display module can also include a comparator. When the display module changes from the first ambient light intensity to the second ambient light intensity, the comparator can compare the first difference between the first and second ambient light intensities or the second difference between the first current and the second current of the second photoelectric converter 300. When the first difference is greater than a first preset difference or the second difference is greater than a second preset difference, the comparator will issue an interrupt. An interrupt means that the display module stops executing the current task and starts executing a new task. After the comparator triggers the interrupt response, the internal current value I of the second photoelectric converter 300 can be detected. When the internal current value I of the second photoelectric converter 300 is greater than a first threshold and less than a second threshold, the display module can enter the first sub-state, such as... Figure 5 As shown. When the internal current value I is greater than the second threshold, the display module can enter the second sub-state, as shown. Figure 4 As shown. When the internal current value I is less than the first threshold, the display module remains in the second state, as shown. Figure 3 As shown. The first state includes a first sub-state and a second sub-state, wherein the number of pixels 110 turned off in the first sub-state is less than the number of pixels turned off in the second sub-state.

[0070] By setting a comparator, the detection of the internal current value I of the second photoelectric converter 300 can be resumed only after the comparator triggers an interrupt, thereby avoiding power loss caused by continuous detection of the internal current value I of the second photoelectric converter 300.

[0071] Optionally, the method for determining ambient light intensity can be based not only on current detection but also on voltage detection; the comparator can be, but is not limited to, a current comparator or a voltage comparator, without specific limitations here.

[0072] like Figure 8 As shown, this application also discloses a control method for a display module, wherein the display module can be the display module disclosed in the above embodiments, and the disclosed control method includes:

[0073] S101, detects ambient light intensity.

[0074] Ambient light intensity can be detected by a light intensity sensor, or indirectly by other means, such as indirectly detecting the ambient light intensity by measuring the current of the second photoelectric conversion element 300 located on the display side of the display body 100.

[0075] S102, the display body 100 is controlled to display at a corresponding resolution according to the ambient light intensity, so that the ambient light passes through the display body 100 and is converted by the first photoelectric conversion element 200.

[0076] It should be noted that ambient light intensity is inversely proportional to display resolution, and display resolution is inversely proportional to the amount of light transmitted to the display subject.

[0077] The control method for the display module disclosed in this application controls the display body 100 to display at a corresponding resolution according to the ambient light intensity, so that the ambient light passes through the display body 100 and is supplied to the first photoelectric conversion element 200 for photoelectric conversion. The first photoelectric conversion element 200 converts solar energy into electrical energy through the photoelectric effect, thereby providing power to the display module or other components of the electronic device. This solves the problem of thicker electronic devices caused by increasing battery capacity to increase battery life in related technologies.

[0078] Optionally, the display module may also include a second photoelectric conversion element 300, which may be disposed on the display side of the display body 100 and may be a light-transmitting structural element.

[0079] Detecting ambient light intensity includes:

[0080] Step A1: Detect the internal current value of the second photoelectric conversion element 300.

[0081] Step A2: Determine the ambient light intensity based on the internal current value of the second photoelectric conversion element 300.

[0082] It should be noted that the internal current value of the second photoelectric conversion element 300 is directly proportional to the ambient light intensity.

[0083] The control method for the display module disclosed in this application determines the ambient light intensity by detecting the internal current value of the second photoelectric converter 300. The photoelectric conversion capability of the display module can be further improved by the second photoelectric converter 300. Moreover, when the display body 100 is displaying, the light emitted by the display body 100 also passes through the second photoelectric converter 300, causing the second photoelectric converter 300 to generate electricity, which is equivalent to recovering and utilizing a portion of the electrical energy used by the display module for display.

[0084] like Figure 9 As shown, optionally, the display subject may include a plurality of pixels 110 arranged in an array, wherein:

[0085] The control display unit 100 adjusts the display resolution according to the ambient light intensity, including:

[0086] S201, determine whether the ambient light intensity is greater than the first preset threshold.

[0087] S202, when the ambient light intensity is greater than a first preset threshold, control a portion of the pixels 110 to be lit and another portion of the pixels 110 to be off, so that the area of ​​the light-transmitting area corresponding to the off-state pixel 110 is proportional to the amount of light transmitted by the display body 100.

[0088] Specifically, the first preset threshold can be a light intensity value preset by the user.

[0089] The control method disclosed in this application changes the display resolution by controlling a portion of the pixels 110 to be lit and another portion of the pixels 110 to be off, thus making the change of display resolution relatively simple and easy to implement.

[0090] Optionally, the disclosed control methods also include:

[0091] S203, when the ambient light intensity is less than or equal to the first preset threshold, controls all pixels 110 to be in the lit state.

[0092] In environments with low light intensity (such as cloudy days, indoors, or at night), solar power generation is not required. Therefore, the display effect of the main display 100 is prioritized, allowing all pixels 110 to be lit up, thereby increasing the display resolution and improving the display effect of the display module.

[0093] like Figure 10 As shown, this application also discloses a control device for a wearable device, the disclosed control device comprising:

[0094] The detection module 501 is used to detect ambient light intensity.

[0095] The control module 502 is used to control the display body 100 to display at a corresponding resolution according to the ambient light intensity, so that the ambient light passes through the display body 100 and is converted by the first photoelectric conversion element 200.

[0096] It should be noted that ambient light intensity is inversely proportional to display resolution, and display resolution is inversely proportional to the amount of light transmitted to the display subject.

[0097] Optionally, the display module may also include a second photoelectric conversion element 300, which may be disposed on the display side of the display body 100. The second photoelectric conversion element 300 may be a light-transmitting structural component. The detection module 501 includes a first detection submodule and a first determination module. The first detection submodule is used to detect the internal current value of the second photoelectric conversion element 300, and the first determination module is used to determine the ambient light intensity based on the internal current value of the second photoelectric conversion element 300.

[0098] It should be noted that the internal current value of the second photoelectric conversion element 300 is directly proportional to the ambient light intensity.

[0099] Optionally, the display body 100 may include a plurality of pixels 110 arranged in an array, wherein:

[0100] The control module 502 is also used to control a portion of the pixels 110 to be lit and another portion of the pixels 110 to be off when the ambient light intensity is greater than a first preset threshold, so that the area of ​​the light-transmitting area corresponding to the off pixel 110 is proportional to the amount of light transmitted by the display body 100.

[0101] Optionally, the disclosed control module 502 is also used to control all of the multiple pixels 110 to be lit when the ambient light intensity is less than or equal to a first preset threshold.

[0102] The methods and steps implemented by the control device for the display module disclosed in this application are the same as or similar to the steps in the control method for the display module disclosed in the above embodiments, and can be referred to each other. They will not be repeated here.

[0103] The display module in the above embodiments can be a display module in a wearable device, and the electronic device in the above embodiments can be a wearable device, such as a smartwatch, smart glasses, or smart bracelet. Of course, the display module is not limited to the display module in a wearable device (especially smartwatches and smart bracelets), and the electronic device is not limited to wearable devices.
