Description

TECHNICAL FIELD

[0001] The disclosure relates to an electronic device, and more particularly, to an electronic device capable of expanding a screen. BACKGROUND

[0002] Currently, a screen expansion method of an electronic device can include implementing a single screen folding, scrolling, or stretching characteristic using a flexible screen. However, such a screen expansion method can have high application dependency on a flexible screen and can have high cost. SUMMARY

[0003] Example embodiments relate to an electronic device capable of expanding a screen while circumventing dependency on and limitations of a flexible screen.

[0004] According to an example embodiment, an electronic device can include a first display panel, a second display panel, a third display panel, a frame supporting the first display panel, the second display panel, and the third display panel, and a deployment mechanism connected to the frame. The deployment mechanism can be configured to drive the first display panel and the second display panel to move in a first direction such that the first display panel, the second display panel, and the third display panel switch between a screen stacked state and a screen tiled state. In the screen tiled state, the first display panel, the second display panel, and the third display panel can be arranged side by side in the first direction and the third display panel can be between the first display panel and the second display panel. In the screen stacked state, the first display panel, the second display panel, and the third display panel can be stacked in a second direction different from the first direction. The deployment mechanism can be configured to control the first display panel, the second display panel, and the third display panel to switch between the screen stacked state and the screen tiled state.

[0005] In some embodiments, the first direction can correspond to a width direction of the first display panel or a length direction of the first display panel, the second display panel, and the third display panel, and the second direction can correspond to a thickness direction of the first display panel, the second display panel, and the third display panel.

[0006] In some embodiments, the frame can include a base frame. The base frame can support the first display panel, the second display panel, the third display panel, and the deployment mechanism. The base frame can slidably support the first display panel and the second display panel such that the first display panel and the second display panel can move in the first direction. The base frame can be configured to provide fixed support for the third display panel such that a position of the third display panel relative to the base frame does not change when the first display panel, the second display panel, and the third display panel switch between the screen stacked state and the screen tiled state.

[0007] In some embodiments, the frame can further include a side frame. The side frame can be mounted on the base frame. The first display panel and the second display panel can be fixed to the side frame.

[0008] In some embodiments, the base frame can include a guide groove, and the side frame can be embedded in the guide groove, such that the first display panel and the second display panel, which can be fixed to the side frame, can be configured to move in the first direction under the guidance of the guide groove.

[0009] In some embodiments, the unfolding mechanism can include a guide rail, a plurality of sliders, a plurality of links, and a motor. The guide rail can be on the back of the third display panel. The guide rail can extend in a third direction. The third direction can be perpendicular to the first direction and the second direction. The plurality of sliders can be in the guide rail and configured to be able to slide along the guide rail. The plurality of links can connect the first display panel and the second display panel to the plurality of sliders. The motor can be configured to provide power. When the plurality of sliders slide along the guide rail in response to the power provided by the motor, the first display panel and the second display panel can move in the first direction opposite to each other.

[0010] In some embodiments, the plurality of sliders can include a first slider and a second slider. The plurality of links can include a first link, a second link, a third link, and a fourth link. The first link can be between the first display panel and the first slider. The second link can be between the second display panel and the first slider. The third link can be between the first display panel and the second slider. The fourth link can be between the second display panel and the second slider.

[0011] In some embodiments, the motor can be configured to supply power to the first slider and the second slider to move the first slider and the second slider away from each other. When the motor moves the first slider and the second slider away from each other, the first display panel and the second display panel can move in the first direction opposite to each other and away from the third display panel, such that the overlapping area of the first display panel, the second display panel, and the third display panel in the second direction can be reduced. The motor can be configured to supply power to the first slider and the second slider to move the first slider and the second slider close to each other. When the motor moves the first slider and the second slider close to each other, the first display panel and the second display panel can move in the first direction opposite to each other and can move close to the third display panel, such that the overlapping area between the first display panel, the second display panel, and the third display panel in the second direction can be increased.

[0012] In some embodiments, the motor can be a linear motor, and the linear motor can be fixed to the frame. An output end of the linear motor can be connected to the plurality of sliders to supply power to the plurality of sliders.

[0013] In some embodiments, in the screen tiling state, the first display panel, the second display panel, and the third display panel are configured to cooperatively display different regions of an image. In the screen stacking state, one of the first display panel, the second display panel, and the third display panel can be configured to separately display an image. The remaining two of the first display panel, the second display panel, and the third display panel can be configured to not display the image.

[0014] In some embodiments, in the screen stacking state, the first display panel, the second display panel, and the third display panel can be configured to cooperatively display different partial source information of an image in full resolution and full color depth by means of sub-layers or sub-color steps. The first display panel, the second display panel, and the third display panel can be configured to perform asynchronous processing in time or space on at least one of the pixels and refresh rates of the first display panel, the second display panel, and the third display panel, and the top two of the first display panel, the second display panel, and the third display panel can be transparent display panels.

[0015] Compared with the screen expansion manner of the electronic device using a flexible screen to realize a folding screen, a rolling screen, a telescopic screen, and the like, the screen expansion manner according to the example embodiments can realize screen expansion by using a conventional screen, which can reduce the dependence on flexible screen materials and technologies, can reduce the cost, and can enhance the display effect.

[0032] Example embodiments will be described in detail below with reference to the accompanying drawings.

[0033] Figure 1 is a block diagram illustrating an electronic device 100 according to an example embodiment.

[0034] Referring to Figure 1 According to an example embodiment, the electronic device 100 includes a plurality of display panels 110, a frame 120, and a deployment mechanism 130.

[0035] The plurality of display panels 110 can include a first display panel, a second display panel, and a third display panel for displaying an image. In one example, any one of the plurality of display panels 110 can include an organic light emitting diode (OLED) display panel or a liquid crystal display (LCD) display panel. However, it should be understood that the present application is not limited thereto, for example, any one of the plurality of display panels 110 can include any type of display panel. Further, in one example, the plurality of display panels 110 can include the same type of display panel, and in another example, the plurality of display panels 110 can include different types of display panels. For the sake of brevity, example embodiments can describe embodiments of the inventive concept with the plurality of display panels including three display panels (e.g., a first display panel, a second display panel, and a third display panel). However, while the present application describes example embodiments with the plurality of display panels 110 including three display panels, the present application is not limited thereto, for example, the plurality of display panels 110 can include two display panels, or four or more display panels.

[0036] The frame 120 can support the first display panel, the second display panel, and the third display panel. In one example, the frame 120 can also support components of the electronic device 100. For example, the frame 120 can also support the unfolding mechanism 130.

[0037] Hereinafter, the frame 120 will be described in detail with reference to Figure 2 and Figure 3

[0038] The unfolding mechanism 130 can be connected to the frame 120, and can be configured to drive the first display panel and the second display panel to move in the first direction X, such that the first display panel, the second display panel, and the third display panel are switched between the screen-stacked state and the screen-tiled state.

[0039] In one example, a portion of the unfolding mechanism 130 can be fixed to the frame 120, and another portion of the unfolding mechanism 130 can be connected to the plurality of display panels 110.

[0040] In one example, the first direction X can correspond to a width or length direction of the first display panel, the second display panel, and the third display panel, and the second direction Y can correspond to a thickness direction of the first display panel, the second display panel, and the third display panel. That is, the first direction X can correspond to a width or length direction of each of the plurality of display panels 110, and the second direction Y can correspond to a thickness direction of each of the plurality of display panels 110. Accordingly, the first direction X can be perpendicular to the second direction Y.

[0041] ​In one example, in the screen tiled state, the first display panel, the second display panel and the third display panel can be arranged side by side in the first direction X and the third display panel can be located between the first display panel and the second display panel. That is, in the screen tiled state, the plurality of display panels 110 can be arranged side by side in the first direction X and the third display panel can be located between the first display panel and the second display panel in the first direction X. Further, in one example, in the screen stacked state, the first display panel, the second display panel and the third display panel can be stacked in the second direction Y. That is, in the screen stacked state, the plurality of display panels 110 can be stacked in the second direction Y.

[0042] Hereinafter, a detailed description will be given of the electronic device 100 according to an example embodiment. Figures 2 to 7 The expansion mechanism 130 is described in detail.

[0043] According to an example embodiment, the expansion mechanism 130 can be controlled such that the first display panel, the second display panel and the third display panel are switched between the screen stacked state and the screen tiled state. In one example, the expansion mechanism 130 can be controlled in a wired or wireless manner and can be provided with various control signals for switching the plurality of display panels 110 to the screen stacked state or the screen tiled state according to a preset program or a user instruction.

[0044] The screen expansion method according to an example embodiment can achieve screen expansion by utilizing a conventional screen, thus reducing dependency on flexible screen materials and technology, reducing costs, and at the same time, enhancing display effects.

[0045] Figure 2 FIG. 1 is a block diagram illustrating an electronic device 100 according to an example embodiment. Figure 3 FIG. 2 is a detailed diagram illustrating a frame 120 of an electronic device according to an example embodiment.

[0046] Referring to FIG. 1, Figure 2 and Figure 3According to an example embodiment, the frame 120 can include a base frame 121. The base frame 121 can support the first display panel, the second display panel, the third display panel, and the unfolding mechanism 130. That is, the base frame 121 can support the plurality of display panels 110 and the unfolding mechanism 130. In one example, the base frame 121 can slidably support the first display panel and the second display panel so that the first display panel and the second display panel can move in the first direction X. That is, the base frame 121 can slidably support one or more display panels among the plurality of display panels 110 that can move in the first direction X. Also, in this example, the base frame 121 can fixedly support the third display panel so that the position of the third display panel relative to the base frame 121 does not change when the first display panel, the second display panel, and the third display panel are switched between the screen stack state and the screen lay state. That is, the base frame 121 can fixedly support one or more display panels among the plurality of display panels 110 that cannot move in the first direction X.

[0047] According to an example embodiment, the frame 120 can further include a side frame 122. The side frame 122 can be mounted on the base frame 121. In one example, the first display panel and the second display panel can be fixed to the side frame 122. That is, the sliding connection between one or more display panels among the plurality of display panels 110 that can move in the first direction X and the base frame 121 can be implemented by fixing the one or more display panels among the plurality of display panels 110 that can move in the first direction X to the side frame 122 mounted on the base frame 121.

[0048] In one example, the base frame 121 can include a guide groove 1211. In this case, the side frame 122 can be embedded in the guide groove 1211 so that the first display panel 111 and the second display panel 112 fixed to the side frame 122 move in the first direction X under the guidance of the guide groove 1211. That is, the side frame 122 can implement the sliding connection between the side frame 122 and the base frame 121 through the guide groove 1211 included in the base frame 121. Accordingly, the sliding connection between one or more display panels among the plurality of display panels 110 that can move in the first direction X and the base frame 121 can be implemented through the sliding connection of the guide groove 1211 between the side frame 122 and the base frame 121.

[0049] Figure 4 is a block diagram illustrating an unfolding mechanism 130 of an electronic device 100 according to an example embodiment. Figures 5 to 7 is a detailed diagram illustrating an unfolding mechanism 130 of an electronic device 100 according to an example embodiment.

[0050] Referring toFigure 4 According to an example embodiment, the unfolding mechanism 130 can include a guide rail 131, a plurality of sliders 132, a plurality of links 133, and a motor 134.

[0051] The guide rail 131 can be disposed at the back of the third display panel. In one example, the guide rail 131 can be fixed to the frame 120 (e.g., the base frame 121). Also, the guide rail 131 can extend in a third direction Z perpendicular to the first direction X and the second direction Y. For example, in one example, when the first direction X corresponds to a length direction of the plurality of display panels, the third direction Z can correspond to a width direction of the plurality of display panels. In another example, when the first direction X corresponds to a width direction of the plurality of display panels, the third direction Z can correspond to a length direction of the plurality of display panels.

[0052] The plurality of sliders 132 can be disposed in the guide rail 131 and can be configured to be slidable along the guide rail 131. Since the guide rail 131 can extend in the third direction Z perpendicular to the first direction X and the second direction Y, the plurality of sliders 132 can slide in the third direction Z perpendicular to the first direction X and the second direction Y. For example, in one example, when the first direction X corresponds to a length direction of the plurality of display panels, the third direction Z can correspond to a width direction of the plurality of display panels, and the plurality of sliders 132 can slide in the width direction of the plurality of display panels. In another example, when the first direction X corresponds to a width direction of the plurality of display panels, the third direction Z can correspond to a length direction of the plurality of display panels, and the plurality of sliders 132 can slide in the length direction of the plurality of display panels.

[0053] The plurality of links 133 can be used to connect the first display panel and the second display panel to the plurality of sliders 132. In one example, the first display panel and the second display panel can include a non-display area. In this case, the plurality of links 133 can connect the first display panel and the second display panel to the plurality of sliders 132 by being connected to the non-display area of the first display panel and the second display panel.

[0054] The motor 134 can be configured to provide power. In one example, the motor 134 can be a linear motor or a numerical control motor. For example, the motor 134 can be controlled in a wired or wireless manner, and can be provided with various control signals for switching the plurality of display panels 110 to the screen-stacked state or the screen-tiled state according to a preset program or a user instruction. In this case, the linear motor can be fixed to the frame 120 (e.g., the base frame 121), and an output end of the linear motor can be connected to the plurality of sliders 132 to provide power to the plurality of sliders 132. For example, in one example, when the plurality of sliders 132 slide along the guide rail 131 by the power provided by the motor 134, the first display panel and the second display panel can move in the first direction X in opposite directions from each other.

[0055] Referring to Figures 5 to 7 In one example, the plurality of sliders 132 can include a first slider 1321 and a second slider 1322, and the plurality of links 133 can include a first link 1331, a second link 1332, a third link 1333, and a fourth link 1334. In this case, the first link 1331 can be disposed between the first display panel 111 and the first slider 1321, the second link 1332 can be disposed between the second display panel 112 and the first slider 1321, the third link 1333 can be disposed between the first display panel 111 and the second slider 1322, and the fourth link 1334 can be disposed between the second display panel 112 and the second slider 1322. In one example, through the above connection structure, when the first slider 1321 and the second slider 1322 are moved away from each other by the power provided by the motor 134, the first display panel 111 and the second display panel 112 can be moved in opposite directions to each other in the first direction X and away from the third display panel 113, so that the overlapping area of the first display panel 111, the second display panel 112, and the third display panel 113 in the second direction Y can be reduced; when the first slider 1321 and the second slider 1322 are moved close to each other by the power provided by the motor 134, the first display panel 111 and the second display panel 112 can be moved in opposite directions to each other in the first direction X and close to the third display panel 113, so that the overlapping area of the first display panel 111, the second display panel 112, and the third display panel 113 in the second direction Y can be increased. In one example embodiment, the sliders 1321 and 1322 can be, but are not limited to, plastic structures that can have a polygonal (e.g., rectangular) shape and can have rounded corners, and the sliders 1321 and 1322 can be attached to the guide rails 131 so that the sliders 1321 and 1322 can slide along the guide rails 131.

[0056] Although Figures 5 to 7 Although the connection relationship of the plurality of sliders 132 and the plurality of links 133 is described by way of example with reference to the case where the plurality of sliders 132 can include the first slider 1321 and the second slider 1322 and the plurality of links 133 can include the first link 1331, the second link 1332, the third link 1333, and the fourth link 1334, the example embodiments are not limited thereto, for example, the plurality of sliders 132 can include three or more sliders, and the plurality of links 133 can include less than four links or more than four links. In addition, although the connection relationship of the plurality of sliders 132 and the plurality of links 133 is described by way of example with reference to the case where the first display panel 111 and the second display panel 112 are disposed on the same side of the third display panel 113, the example embodiments are not limited thereto, for example, the first display panel 111 and the second display panel 112 can be disposed on different sides of the third display panel 113. Figures 5 to 7An example is described in which the first display panel 111 and the second display panel 112 can move away from the third display panel 113 in the first direction X in reverse to each other when the first slider 1321 and the second slider 1322 are moved away from each other by the power supplied by the motor 134, and the first display panel 111 and the second display panel 112 can move close to the third display panel 113 in the first direction X in reverse to each other when the first slider 1321 and the second slider 1322 are moved close to each other by the power supplied by the motor 134, but the present application is not limited thereto. For example, in another example, by other connection structures, when the first slider 1321 and the second slider 1322 are moved close to each other by the power supplied by the motor 134, the first display panel 111 and the second display panel 112 can move in reverse to each other in the first direction X and close to the third display panel 113, so that the overlapping area of the first display panel 111, the second display panel 112, and the third display panel 113 in the second direction Y can increase, and when the first slider 1321 and the second slider 1322 are moved away from each other by the power supplied by the motor 134, the first display panel 111 and the second display panel 112 can move in reverse to each other in the first direction X and away from the third display panel 113, so that the overlapping area of the first display panel 111, the second display panel 112, and the third display panel 113 in the second direction Y can decrease. In some embodiments, the motor 134 can move the first slider 1321 and the second slider 1322 close to each other or away from each other based on reversing the polarity of the power supplied to the first slider 1321 and the second slider 1322, but example embodiments are not limited thereto. The motor 134 can be electrically connected to the first slider 1321 and the second slider 1322 through a conductive element such as a metal contact or a wire, but example embodiments are not limited thereto.

[0057] Figure 8 FIG. 1 is a diagram illustrating an electronic device 100 according to an example embodiment. Figure 9 FIG. 2 is a diagram illustrating a second display mode of the electronic device 100 according to an example embodiment. Figure 10 FIG. 3 is a diagram illustrating a third display mode of the electronic device 100 according to an example embodiment.

[0058] According to example embodiments, the electronic device 100 can have a plurality of display modes. The plurality of display modes can include a first display mode, a second display mode, and a third display mode. The first display mode or the second display mode can be enabled when the electronic device 100 is in a screen stack state. Referring to FIGS. 1 to 3, the first display mode and the second display mode will be described. Figure 8For the first display mode, in the screen stacking state, one of the first display panel, the second display panel and the third display panel can be configured to display an image alone, and the remaining two of the first display panel, the second display panel and the third display panel can be configured not to display an image. For example, in one example, for the first display mode, in the screen stacking state, the uppermost one of the stacked multiple display panels can be configured to display an image alone (single screen operation), and the remaining one or more of the stacked multiple display panels can be configured not to display an image or in an off state to meet normal display, effectively reducing power consumption. In another example, for the first display mode, in the screen stacking state, a designated one of the stacked multiple display panels can be configured to display an image alone, and the display panels stacked above the designated display panel can be configured as transparent display panels, so that the designated display panel can display an image alone through the transparent display panels stacked above. The first display panel, the second display panel and the third display panel are simultaneously independently connected to the display chip. In the first display mode, a single display panel is in operation, the display chip outputs normal image information A to the single display panel for display, and the other two display panels are not in operation. Therefore, the first display mode can be referred to as a normal display mode.

[0059] Referring to Figure 9 For the second display mode, in the screen stacking state, the first display panel, the second display panel and the third display panel can be configured to display different partial source information of an image in full resolution and full color depth by means of partial layer or partial color step, the first display panel, the second display panel and the third display panel are configured to perform asynchronous processing on the pixels and / or refresh rate of the first display panel, the second display panel and the third display panel in time or space, and the uppermost two of the first display panel, the second display panel and the third display panel are transparent display panels. For example, the first display panel can be a transparent screen 1 in Figure 9 , the second display panel can be a transparent screen 2 in Figure 9 , and the third display panel can be an OLED screen 3 in Figure 9 , the first display panel, the second display panel and the third display panel work cooperatively under the driving of one display chip to display more original data from the display chip by means of partial layer or partial color step to display as much image detail information and color fullness and fineness as possible, thereby superimposing the display effect and improving the display detail. However, it should be understood that although Figure 9The first display panel and the second display panel are taken as transparent screens and the third display panel is located below the first display panel and the second display panel, but the example embodiments are not limited thereto, for example, the third display panel can be located above the first display panel and the second display panel or between the first display panel and the second display panel, and the uppermost two display panels among the first display panel, the second display panel and the third display panel can be transparent screens. The first display panel, the second display panel and the third display panel work cooperatively, and the display chip outputs original image deep level layer information A1, A2 and A3 to the first display panel, the second display panel and the third display panel respectively through algorithm processing. Since the sum (A1+A2+A3) of the image information contained by the first display panel, the second display panel and the third display panel is much larger than the conventional image information A, the display precision, resolution and color quality saturation are greatly improved, thereby enhancing the display effect. Therefore, the second display mode can be referred to as an enhanced display mode.

[0060] When the electronic device 100 is in the screen tiling state, the third display mode can be enabled. Referring to Figure 10 , for the third display mode, in the screen tiling state, the first display panel, the second display panel and the third display panel can be configured to cooperatively display different regions of an image. For example, the first display panel can display a first region of the image, the second display panel can display a second region of the image, and the third display panel can display a remaining region of the image. In the third display mode, the first display panel, the second display panel and the third display panel are expanded by a stretching manner to a display screen close to 3 times in size, and the screen expansion rate is close to 300%. The first display panel, the second display panel and the third display panel work cooperatively, and the display chip outputs partial image information A', B' and C' to the first display panel, the second display panel and the third display panel respectively through algorithm processing. The complete image is displayed by splicing the partial screen image information A', B' and C', the display panel size Z(A', B', C') is greater than the size Z(A) of a single display panel, and thus the screen expansion is realized. Therefore, the third display mode can be referred to as an expanded display mode.

[0061] Compared with the screen expansion mode of the electronic device using the flexible screen to realize the folding screen, the scrolling screen and the stretching screen, the screen expansion mode according to the example embodiments can realize the screen expansion by using the conventional screen, thereby reducing the dependence on the flexible screen material and technology, reducing the cost, and enhancing the display effect.

[0062] The electronic device 100 can include processing circuitry (such as hardware including logic circuitry; a hardware / software combination (such as a processor executing software), or a combination thereof). For example, the processing circuitry can more specifically include, but is not limited to, a central processing unit (CPU), an arithmetic logic unit (ALU), a digital signal processor, a microcomputer, a field programmable gate array (FPGA), a system on chip (SoC), a programmable logic unit, a microprocessor, an application specific integrated circuit (ASIC), etc., which can include a memory such as a volatile memory device (e.g., SRAM, DRAM, SDRAM) and / or a non-volatile memory (e.g., a flash memory device, a phase change memory, a ferroelectric memory device). The memory can store a preset program and / or instructions, which, when executed by the processing circuitry, configure the processing circuitry as a special-purpose processing circuitry for controlling the operation of the electronic device 100 described herein (such as controlling the motor 134 and the unfolding mechanism 150 to switch the plurality of display panels 110 to a screen-stacked state or a screen-tiled device according to the preset program and / or instructions, controlling the power supplied by the motor 134, controlling the display mode using the display panels 111 to 113 during the screen-stacked state and the screen-tiled state, and performing other functions of the electronic device 100 described herein) according to the preset program and / or instructions.

[0063] While the inventive concept has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those skilled in the art that various changes in form and details can be made therein without departing from the spirit and scope of the inventive concept as defined by the appended claims.
