Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a display panel, display device, control method, and electronic device. Background Technology

[0002] With the widespread application of smart terminal devices, the functions integrated into these devices are becoming increasingly integrated, and people are becoming more and more reliant on them. Taking smartphones as an example, smartphones have become an indispensable part of people's lives, but due to limitations in phone space and battery technology, limited usage time has become a major pain point for users. As a crucial component for human-computer interaction, reducing display power consumption has become a focus of effort across the entire industry. Summary of the Invention

[0003] This application provides a display panel, display device, control method, and electronic device to solve the problem of excessive power consumption in existing display panels.

[0004] To solve the above-mentioned technical problems, this application is implemented as follows:

[0005] In a first aspect, embodiments of this application provide a display panel, comprising: a substrate; display units, wherein a plurality of display units are arrayed on the substrate, at least one display unit includes a light-emitting unit and an ink unit, the ink unit including ink particles, the ink particles being used to reflect light to achieve display; and driving electrodes disposed on the substrate, the driving electrodes including a first driving electrode and a second driving electrode, the first driving electrode being used to drive the light-emitting unit, and the second driving electrode being used to drive the ink particles of the ink unit to move.

[0006] Secondly, embodiments of this application also provide a display device, including the display panel described above.

[0007] Thirdly, embodiments of this application also provide a method for controlling a display panel, wherein the display panel is the aforementioned display panel, and the control method includes:

[0008] Obtain the information to be displayed from the display panel, including static and dynamic display information;

[0009] Control the ink unit to display static information;

[0010] Control the light-emitting unit to display dynamic information.

[0011] Fourthly, embodiments of this application also provide an electronic device, including a processor, a memory, and a computer program stored in the memory and executable on the processor, wherein the computer program, when executed by the processor, implements the steps of the control method described above.

[0012] Thus, in the display panel provided in this application embodiment, the display panel includes a substrate and display units and driving electrodes disposed on the substrate. At least some display units include light-emitting units and ink units. The light-emitting units emit light to achieve display, and the ink particles in the ink units reflect light to achieve image display. The first driving electrode and the second driving electrode independently drive the light-emitting units and the ink units. During the use of the display panel, the light-emitting units or the ink units can be controlled independently or jointly to display according to usage requirements. When the ink units display, the ink units utilize ink particles to reflect external light for display. The ink particles do not need to emit light themselves; only the second driving electrode needs to control the movement of the ink particles to achieve the display of a specific image, thus effectively reducing the power consumption of the display panel. Therefore, by setting at least some display units as independently controlled light-emitting units and ink units, this application embodiment can effectively reduce the power consumption of the display panel.

[0027] To make the technical problems, technical solutions and advantages of this application clearer, a detailed description will be provided below in conjunction with the accompanying drawings and specific embodiments.

[0028] Please refer to the following: Figures 1 to 3 , Figure 1 This is a schematic diagram of the structure of the display panel 10 according to an embodiment of this application; Figure 2 for Figure 1 A magnified schematic diagram of a partial structure in one example; Figure 3 for Figure 2 Sectional view at point AA.

[0029] like Figures 1 to 3 As shown, in a first aspect, embodiments of this application provide a display panel 10, including a substrate 100, display units 200, and driving electrodes 300. A plurality of display units 200 are arrayed on the substrate 100, and at least one display unit 200 includes a light-emitting unit 210 and an ink unit 220. The ink unit 220 includes ink particles 221, which are used to reflect light to achieve display. The driving electrode 300 is disposed on the substrate 100 and includes a first driving electrode 310 and a second driving electrode 320. The first driving electrode 310 is used to drive the light-emitting unit 210, and the second driving electrode 320 is used to drive the movement of the ink particles 221 of the ink unit 220.

[0030] Thus, in the display panel 10 provided in this embodiment, the display panel 10 includes a substrate 100 and display units 200 and driving electrodes 300 disposed on the substrate 100. At least a portion of the display units 200 includes light-emitting units 210 and ink units 220. The light-emitting units 210 emit light to achieve display, and the ink particles 221 in the ink units 220 reflect light to achieve image display. The first driving electrode 310 and the second driving electrode 320 of the driving electrodes 300 independently drive the light-emitting units 210 and the ink units 220. During the use of the display panel 10, the light-emitting units 210 or the ink units 220 can be controlled to display independently or together according to usage requirements. When the ink units 220 display, the ink units 220 use ink particles 221 to reflect external light for display. The ink particles 221 do not need to emit light themselves; only the second driving electrode 320 needs to control the movement of the ink particles 221 to achieve the display of a specific image, thus effectively reducing the power consumption of the display panel 10. Therefore, by configuring at least some of the display units 200 as independently controlled light-emitting units 210 and ink units 220, the power consumption of the display panel 10 can be effectively reduced.

[0031] There are various types and arrangements of the light-emitting unit 210. For example, the light-emitting unit 210 may include at least one of the following: organic light-emitting diode (OLED), micro light-emitting diode (Micro LED).

[0032] The ink particles 221 of the ink unit 220 are used to reflect light. For example, different colors of ink particles 221 can be set to achieve color display of the display panel 10.

[0033] In the display panel 10 provided in this embodiment, some display units 200 may simultaneously include a light-emitting unit 210 and an ink unit 220, while other display units 200 may only include a light-emitting unit 210, to improve the display effect of the display panel 10. Alternatively, another portion of the display units 200 may include an ink unit 220 to reduce the power consumption of the display panel 10. Optionally, all display units 200 of the display panel 10 may include both a light-emitting unit 210 and an ink unit 220.

[0034] Optionally, the second driving electrode 320 is used to generate an electric field and can control the magnitude of the electric field so that the ink particles 221 move under the drive of the electric field force. The second driving electrode 320 drives the movement of the ink particles 221 so that the multiple ink units 220 can realize the display of the image.

[0035] In some alternative embodiments, please continue to refer to Figure 2 and Figure 3 The ink unit 220 includes a wall portion 222, which is disposed on the substrate 100 and encloses a receiving space. Ink particles 221 are disposed in the receiving space, and the second driving electrode 320 is used to drive the ink particles 221 to move within the receiving space.

[0036] In these alternative embodiments, by providing the wall portion 222, the ink particles 221 of a single ink unit 220 can be confined within the receiving space, preventing the ink particles 221 from scattering within the display panel 10 and affecting other structures of the display panel 10.

[0037] There are various ways to set the wall portion 222. The wall portion 222 can be made of organic or inorganic insulating materials. When the wall portion 222 is made of insulating material, the second driving electrode 320 can be set on the surface of the wall portion 222 facing or away from the accommodating space, so as to increase the distribution area of ​​the second driving electrode 320 and improve the control effect of the second driving electrode 320 on the ink particles 221.

[0038] In other alternative embodiments, please continue to refer to Figure 2 and Figure 3 The second driving electrode 320 can also be reused as at least part of the wall portion 222. That is, the second driving electrode 320 can not only drive the ink particles 221 to move, but also confine the ink particles 221 within the receiving space. This eliminates the need to simultaneously provide an insulating wall portion 222 and a conductive second driving electrode 320, simplifying the structure of the display panel 10. In addition, the second driving electrode 320 can also reflect more light to the ink particles 221, improving the display effect of the ink unit 220.

[0039] Please refer to the following: Figures 2 to 5 , Figure 4 for Figure 1 A magnified schematic diagram of the structure of Q in another example; Figure 5 for Figure 4 Sectional view at point BB. Figure 4 and Figure 2 The difference lies in the fact that the ink units 220 of the display unit 200 of the display panel 10 are in different display states.

[0040] In some alternative embodiments, such as Figures 2 to 5 As shown, the display panel 10 also includes a shielding portion 230, which is disposed on the wall portion 222, and at least a portion of the shielding portion 230 and the substrate 100 are spaced apart to form a shielding space. The second driving electrode 320 is also used to drive ink particles 221 to move to the shielding space.

[0041] In these alternative embodiments, a shielding portion 230 is provided on the wall portion 222, and the shielding space formed between the shielding portion 230 and the substrate 100 can accommodate ink particles 221. For example... Figure 2 and Figure 3 As shown, when the ink unit 220 is displaying, the ink unit 220 is located in the receiving space and is not obstructed by the obstruction part 230. Figure 4 and Figure 5 As shown, when the ink unit 220 does not need to display, the second driving electrode 320 can drive the ink particles 221 to move to the occlusion space, thereby hiding the ink particles 221, increasing the light transmittance of other positions in the accommodating space, and thus increasing the light transmittance of the display panel 10. This allows the display panel 10 to still have a certain light transmittance when the light-emitting unit 210 is displaying, enabling the display panel 10 to achieve transparent display.

[0042] There are several ways to set up the shielding part 230; please refer to further information. Figure 2 and Figure 3 The shielding part 230 can be provided on the surface of the wall part 222 facing the receiving space.

[0043] Please see Figure 6 and Figure 7 , Figure 6 for Figure 1 A magnified schematic diagram of the structure of Q in another example; Figure 7 for Figure 6 Sectional view at point BB.

[0044] In some alternative embodiments, such as Figure 6 and Figure 7 As shown, the shielding portion 230 is disposed on the side of the wall portion 222 away from the substrate 100, and at least the shielding portion 230 extends toward the receiving space to form a shielding space with the substrate 100.

[0045] In these alternative embodiments, the shielding portion 230 can be attached to the wall portion 222, and at least a portion of the wall portion 222 can extend outward toward the receiving space. The distance between the wall portion 222 extending into the receiving space and the substrate 100 is large, which can increase the size of the shielding space.

[0046] There are various ways to arrange the distribution pattern of the blocking portion 230. The blocking portion 230 can be consistent with the extension path of the wall portion 222, that is, the blocking portion 230 can be arranged in a closed ring around the ink particle 221. Alternatively, the blocking portion 230 can also be arranged on part of the wall portion 222, that is, the blocking portion 230 is a non-closed ring. The blocking portion 230 is arranged on at least one side of the circumferential direction of the receiving space. As long as the second driving electrode 320 can drive the ink particle 221 to the blocking space of the blocking portion 230 facing the substrate 100, it is acceptable.

[0047] There are various ways to fabricate the shielding portion 230 and the wall portion 222. For example, the wall portion 222 can be formed by reusing the second driving electrode 320. The wall portion 222 includes a metal material, and the shielding portion 230 also includes a metal material, but the metal materials of the shielding portion 230 and the second driving electrode 320 are different. The shielding portion 230 and the wall portion 222 can be fabricated using a wet etching process. By controlling the composition of the etching solution, the etching rate of the metal material used to fabricate the second driving electrode 320 is made greater than the etching rate of the metal material used to fabricate the shielding portion 230, thereby forming a larger shielding portion 230 and a smaller wall portion 222.

[0048] Optionally, the wall portion 222 includes a first segment 222a and a second segment 222b. The first segment 222a is located between the light-emitting unit 210 and the ink unit 220 to isolate the light-emitting unit 210 and the ink unit 220; the second segment 222b is connected to both ends of the first segment 222a and encloses the first segment 222a to form a receiving space, and the second driving electrode 320 is reused as the second segment 222b.

[0049] In these optional embodiments, the wall portion 222 includes two parts. The first segment 222a of the wall portion 222 is used to isolate the light-emitting unit 210 and the ink unit 220. The second segment 222b of the wall portion 222 is formed by reusing the second driving electrode 320. On the one hand, it can increase the distribution area of ​​the second driving electrode 320. On the other hand, it can avoid affecting the light-emitting effect of the light-emitting unit 210 when the second driving electrode 320 is reused as the first segment 222a.

[0050] There are various ways to set the material of the first segment 222a. The first segment 222a can be made of insulating material that can be light-transmitting or light-blocking.

[0051] The display unit 200 can be shaped in various ways. Optionally, the display unit 200 can be rectangular in its orthographic projection onto the substrate 100, and the light-emitting unit 210 and the ink unit 220 can be arranged in a 1:1 ratio. In other embodiments, the light-emitting unit 210 is positioned near one of the top corners of the display unit 200. In this case, the first segment 222a can be L-shaped, and the second segment 222b connects to both ends of the L-shaped first segment 222a and encloses the first segment 222a to form an accommodating space.

[0052] In some alternative embodiments, the shielding portion 230 and the second driving electrode 320 are disposed on the same side of the ink particle 221.

[0053] In these optional embodiments, when the second driving electrode 320 drives the ink particles 221 to move, the electric field force near the second driving electrode 320 is relatively large, resulting in a greater control force on the ink particles 221, allowing the ink particles 221 to move quickly to the vicinity of the second driving electrode 320. By placing the blocking part 230 and the second driving electrode 320 on the same side of the ink particles 221, when the light-emitting unit 210 emits light, the speed at which the ink particles 221 are blocked can be increased, thereby improving the display effect of the display panel 10.

[0054] Optionally, as described above, when the second driving electrode 320 is reused as the second segment 222b, the blocking portion 230 is disposed on the side of the second segment 222b away from the substrate 100, so as to reduce the distance between the blocking portion 230 and the second driving electrode 320 and increase the speed at which ink particles 221 are blocked.

[0055] In some optional embodiments, the display panel 10 further includes an encapsulation layer 400, which is located on the side of the display unit 200 and the driving electrode 300 facing away from the substrate 100. The encapsulation layer 400, together with the wall portion 220 and the substrate 100, encapsulates the receiving space and provides protection to the ink particles 221. Optionally, the encapsulation layer 400 is disposed throughout and also encapsulates the light-emitting unit 210, so that the encapsulation layer 400 can provide protection to the light-emitting unit 210.

[0056] In some optional embodiments, in the same display unit 200, the light-emitting unit 210 emits the same color as the ink particles 221.

[0057] In these optional embodiments, the light-emitting unit 210 and the ink particles 221 in the same display unit 200 display the same color, which can improve the color shift problem of the display panel 10. In addition, when the light-emitting color of the light-emitting unit 210 is the same as the color of the ink particles 221, the ink particles 221 can be used to assist the light-emitting unit 210 in display, so the brightness of the light-emitting unit 210 can be appropriately reduced, further reducing the power consumption of the display panel 10.

[0058] In some alternative embodiments, in the same display unit 200, the projected area of ​​the ink unit 220 on the substrate 100 is larger than the projected area of ​​the light-emitting unit 210 on the substrate 100.

[0059] In these alternative embodiments, as described above, when the light-emitting unit 210 emits light, the second driving electrode 320 can drive the ink particles 221 to move and be blocked, thereby increasing the light transmittance of the accommodating space. When the distribution area of ​​the ink units 220 is large, the light transmittance of the display panel 10 can be further improved.

[0060] In some optional embodiments, the display unit 200 includes a red display unit 200a, a blue display unit 200c, and a green display unit 200b. Each of the red display unit 200a, blue display unit 200c, and green display unit 200b includes a light-emitting unit 210 and an ink unit 220. In the red display unit 200a, blue display unit 200c, and green display unit 200b, the light-emitting unit 210 has an equal projected area on the substrate 100, and / or the ink unit 220 has an equal projected area on the substrate 100.

[0061] In these alternative embodiments, the light-emitting units 210 and / or ink units 220 of different colors have equal projected areas on the substrate 100, which can improve the color shift problem of the display panel 10.

[0062] The second aspect of this application also provides a display device, including the display panel 10 of any of the first aspect embodiments described above. Since the display device provided in the second aspect of this application includes the display panel 10 of any of the first aspect embodiments described above, it has the beneficial effects of the display panel 10 of any of the first aspect embodiments described above, which will not be elaborated further here.

[0063] The display devices in this application include, but are not limited to, mobile phones, personal digital assistants (PDAs), tablet computers, e-books, televisions, access control systems, smart landline phones, control consoles, and other devices with display functions.

[0064] Please see Figure 8 , Figure 8 This is a flowchart illustrating a control method provided in an embodiment of this application.

[0065] An embodiment of the third aspect of this application provides a method for controlling a display panel 10. The display panel 10 can be any of the display panels 10 described in the first aspect embodiment above, such as... Figures 1 to 8 As shown, the control methods include:

[0066] Step S01: Obtain the information to be displayed from the display panel 10. The information to be displayed includes static display information and dynamic display information.

[0067] Optionally, the information to be displayed may include the screen information and display type to be displayed on the display panel 10. The display type may include, for example, dynamic video, games, video calls, e-book reading, news display, etc.

[0068] Step S02: Control the ink unit 220 to display static display information.

[0069] Step S03: Control the light-emitting unit 210 to display dynamic display information.

[0070] Static display information can include e-book reading, news reading, and other similar content, which do not require a high refresh rate or frequent screen refreshes. Optionally, static display information can be information whose display is unaffected by a refresh rate below 20 frames per second. Conversely, dynamic display information can include video streaming, video playback, games, and other similar content, which require a higher refresh rate. Dynamic display information can be information whose display is best achieved with a refresh rate above 20 frames per second.

[0071] In step S02, when the information to be displayed is static, the ink particles 221 in the ink unit 220 can be moved by the second driving electrode 320 to display the image. Optionally, in step S02, when the ink unit 220 displays static information in the same display unit 200, the light-emitting unit 210 can be turned off by the first driving electrode 310. In step S03, when the information to be displayed includes dynamic information, the light-emitting unit 210 is controlled to emit light by the first driving electrode 310 to display the image. In step S03, when the information to be displayed is dynamic information, when the light-emitting unit 210 in the same display unit 200 is used to display dynamic information, the ink particles 221 in the ink unit 220 can also be moved to a designated position by the second driving electrode 320. For example, the ink particles 221 in the ink unit 220 can be driven by the second driving electrode 320 to assist the light-emitting unit 210 in displaying, or the ink particles 221 in the ink unit 220 can be driven by the second driving electrode 320 to hide.

[0072] Optionally, when the information to be displayed on the display panel is static, such as when the display panel is used for e-book reading or news reading, the ink units 220 of all display units 200 can be controlled to be in display mode, and all light-emitting units 210 can be controlled to be in off mode. Optionally, when the information to be displayed on the display panel is dynamic, such as when the display panel is used for playing dynamic video, the light-emitting units 210 of all display units 200 can be controlled to be in display mode, and all ink units 220 can be controlled to be in off mode. When the information to be displayed on the display panel includes both static and dynamic information, such as when the display panel is used for displaying PPT, the light-emitting units 210 of some display units 200 can be controlled to be in display mode, and the ink units 220 of other display units 200 can be controlled to be in display mode.

[0073] In the control method of the display panel 10 provided in this application embodiment, the information to be displayed is first obtained through step S01, and then the working state of the light-emitting unit 210 and the ink unit 220 is controlled according to the information to be displayed in steps S02 and S03. When the information to be displayed is static display information, the ink unit 220 is controlled to be in the display state, which can effectively reduce the power consumption of the display panel 10. When the information to be displayed is dynamic display information, the light-emitting unit 210 is controlled to be in the display state, which can ensure the display effect of the display panel 10.

[0074] As described above, when the display panel 10 includes a wall portion 222 and a blocking portion 230, step S03 further includes: when the information to be displayed is dynamic display information, controlling the light-emitting unit 210 in the same display unit 200 to be in the display unit, and moving the ink particles 221 of the ink unit 220 to the blocking space. In these optional embodiments, when the information to be displayed is dynamic display information, moving the ink particles 221 to the blocking space can improve the light transmittance of the accommodating space, thereby enabling the display panel 10 to be both light-transmitting and displayable.
