[0047] In FIG. 1, for convenience of explanation, the display device (100) is depicted as an electronic paper display device or an electrophoretic display device, but is not limited thereto.

[0048] According to an embodiment, the electrophoretic display device may include a display panel having characteristics similar to paper print using electronic ink (e-ink).

[0049] According to an embodiment, the electrophoretic display device can provide content by reflecting external light without a backlight. Since the electrophoretic display device provides content using natural light without emitting light, it can operate at low power.

[0050] According to an embodiment, the electrophoretic display device consumes power only when refreshing the screen due to a change in content, and after refreshing the screen, it can continuously display the screen without additional power consumption. Due to these advantages, the electrophoretic display device is utilized in e-books, price displays, menus, etc.

[0051] As an example, the electrophoretic display device includes microcapsules, and each of the microcapsules may include a positively charged white particle and a negatively charged black particle.

[0052] According to an embodiment, an electrophoretic display device can determine the color of each pixel by using an electric field to move white particles or black particles to a surface (or the front of the electrophoretic display device). For example, the electrophoretic display device can display content (e.g., images, text) by determining the color of each pixel by applying a negative charge to move white particles to the front or applying a positive charge to move black particles to the front.

[0053] However, this is not limited thereto, and each of the microcapsules may include various colored particles in addition to white and black particles. For example, each of the microcapsules may further include various colored particles such as red, green, and blue particles, and the colors included in the content can be expressed through these various colored particles.

[0054] According to an embodiment, the display device (100) communicates with the server (200) and can receive and provide content from the server (200).

[0055] According to an embodiment, when content is received from a server (200), the display device (100) consumes power to update the screen to provide the content and can provide the content without additional power consumption. Additionally, while the display device (100) is providing content, when changed content is received from the server (200), the display device (100) consumes power to update the screen to provide the changed content and can provide the changed content without additional power consumption.

[0056] FIG. 2 is a block diagram of an exemplary display device capable of performing the operations described according to an embodiment of the present disclosure.

[0057] Referring to FIG. 2, a display device (100) according to an embodiment may include a display panel (110), a memory (120), and at least one processor (130).

[0058] According to the embodiment, the display panel (110) can be implemented as various types of display panels such as LCD (liquid crystal display), OLED (organic light-emitting diode), LCoS (Liquid Crystal on Silicon), DLP (Digital Light Processing), QD (quantum dot) display panel, QLED (quantum dot light-emitting diodes), μLED (Micro light-emitting diodes), Mini LED, etc. Meanwhile, the display panel (110) may be implemented as a touch screen combined with a touch sensor, a flexible display, a rollable display, a 3D display, a display in which a plurality of display modules are physically connected, etc.

[0059] According to an embodiment, the display panel (110) may be implemented as an electrophoretic display and may be implemented as a display having characteristics similar to paper print using electronic ink (e-ink) as described above. According to one embodiment, the display panel (110) may provide an image by reflecting external light without a separate backlight. For example, the display panel (110) may operate at low power because it does not emit light and provides an image using natural light (or reflected light).

[0060] For example, if the display panel (110) is implemented as an electrophoretic display (or, EPD), the display panel (110) may require power (e.g., electrical energy) only when the screen is switched (or, updated).

[0061] According to an embodiment, the memory (120) may store data necessary for various embodiments of the present disclosure. According to an embodiment, the memory (120) may be implemented in the form of a memory embedded in the display device (100) or in the form of a memory that can be attached to and detached from the display device (100), depending on the purpose of data storage.

[0062] For example, data for driving the display device (100) may be stored in memory embedded in the display device (100), and data for the extended function of the display device (100) may be stored in memory that is detachable from the display device (100). Meanwhile, the memory embedded in the display device (100) may be implemented as at least one of volatile memory (e.g., DRAM (dynamic RAM), SRAM (static RAM), or SDRAM (synchronous dynamic RAM), etc.), non-volatile memory (e.g., OTPROM (one-time programmable ROM), PROM (programmable ROM), EPROM (erasable and programmable ROM), EEPROM (electrically erasable and programmable ROM), mask ROM, flash ROM, flash memory (e.g., NAND flash or NOR flash, etc.), a hard drive, or a solid-state drive (SSD). Additionally, the memory that is detachable from the display device (100) may be implemented in the form of a memory card (e.g., CF (compact flash), SD (secure digital), Micro-SD (micro secure digital), Mini-SD (mini secure digital), xD (extreme digital), MMC (multi-media card), etc.), or external memory connectable to a USB port (e.g., USB memory). there is.

[0063] According to an embodiment, the memory (120) may store at least one instruction or a computer program including instructions for controlling the display device (100).

[0064] According to an embodiment, at least one processor (130) controls the overall operation of the display device (100). Specifically, at least one processor (130) is connected to each component of the display device (100) and can control the overall operation of the display device (100).

[0065] At least one processor (130) according to an embodiment can perform the operation of an electronic device (100) according to various embodiments by executing at least one instruction stored in memory (120).

[0066] According to an embodiment, at least one processor (130) may be implemented as a digital signal processor (DSP) that processes digital signals, a microprocessor, or a TCON (Timing controller). However, it is not limited thereto, and may include or be defined by one or more of a central processing unit (CPU), a Micro Controller Unit (MCU), a micro processing unit (MPU), a controller, an application processor (AP), a communication processor (CP), an ARM processor, or an AI (Artificial Intelligence) processor. Additionally, at least one processor (130) may be implemented as a System on Chip (SoC) or Large Scale Integration (LSI) with a built-in processing algorithm, or may be implemented in the form of a Field Programmable Gate Array (FPGA). At least one processor (130) can perform various functions by executing computer executable instructions stored in memory.

[0067] At least one processor (130) may include one or more of a CPU (Central Processing Unit), GPU (Graphics Processing Unit), APU (Accelerated Processing Unit), MIC (Many Integrated Core), DSP (Digital Signal Processor), NPU (Neural Processing Unit), hardware accelerator, or machine learning accelerator. At least one processor (130) may control one or any combination of other components of an electronic device and may perform operations or data processing related to communication. At least one processor (130) may execute one or more programs or instructions stored in memory. For example, at least one processor (130) may perform a method according to an embodiment of the present disclosure by executing one or more instructions stored in memory.

[0068] When the method according to an embodiment of the present disclosure includes a plurality of operations, the plurality of operations may be performed by a single processor or by a plurality of processors. For example, when a first operation, a second operation, and a third operation are performed by the method according to an embodiment, the first operation, the second operation, and the third operation may all be performed by a first processor, or the first operation and the second operation may be performed by a first processor (e.g., a general-purpose processor) and the third operation may be performed by a second processor (e.g., an artificial intelligence dedicated processor).

[0069] At least one processor (130) may be implemented as a single-core processor including one core, or as one or more multi-core processors including multiple cores (e.g., homogeneous multi-core or heterogeneous multi-core). When at least one processor (130) is implemented as a multi-core processor, each of the multiple cores included in the multi-core processor may include internal processor memory such as cache memory or on-chip memory, and a common cache shared by multiple cores may be included in the multi-core processor. Additionally, each of the multiple cores included in the multi-core processor (or some of the multiple cores) may independently read and execute program instructions for implementing the method according to the embodiment of the present disclosure, or all (or some) of the multiple cores may be linked together to read and execute program instructions for implementing the method according to the embodiment of the present disclosure.

[0070] When the method according to an embodiment of the present disclosure includes a plurality of operations, the plurality of operations may be performed by one of the plurality of cores included in a multi-core processor, or may be performed by a plurality of cores. For example, when a first operation, a second operation, and a third operation are performed by the method according to an embodiment, the first operation, the second operation, and the third operation may all be performed by a first core included in a multi-core processor, or the first operation and the second operation may be performed by a first core included in a multi-core processor and the third operation may be performed by a second core included in a multi-core processor.

[0071] In the embodiments of the present disclosure, the processor may mean a system-on-chip (SoC) in which at least one processor and other electronic components are integrated, a single-core processor, a multi-core processor, or a core included in a single-core processor or a multi-core processor, wherein the core may be implemented as a CPU, GPU, APU, MIC, DSP, NPU, hardware accelerator, or machine learning accelerator, but the embodiments of the present disclosure are not limited thereto.

[0072] FIG. 3 is a drawing illustrating a display device that displays a second content in which a portion of the first content is modified according to an embodiment of the present disclosure.

[0073] A display device (100) according to an embodiment of the present disclosure can display a first content (A) on a display panel (110). For example, the display device (100) can receive the first content (A) from a server (200) and display the first content (A).

[0074] According to an embodiment, if the display device (100) is implemented as an electrophoretic display device, the display device (100) can consume power to update the display panel (110) (e.g., electrophoretic display) to provide the first content (A).

[0075] For example, the display device (100) can control the display panel (110) (e.g., electrophoretic display) by using an electric field to control each of the microcapsules to move either a positively charged white particle or a negatively charged black particle contained in each of the microcapsules, thereby providing a screen corresponding to the first content (A).

[0076] According to an embodiment, the display device (100) can provide changed content (hereinafter, second content (B)).

[0077] For example, the second content (B) may include content in which some area (1) of the first content (A) has been changed.

[0078] According to an embodiment, the display device (100) may be implemented as an electrophoretic display device that primarily displays content that does not have frequent frame changes (e.g., 60fps), such as price displays or menu boards, or content that occurs at preset time intervals (e.g., 24 hours), unlike cases where frame changes occur frequently (e.g., 60fps), such as movie content or game content.

[0079] According to the embodiment, between the previous content (e.g., first content (A)) and the new content (or changed content) (e.g., second content (B)) provided by the display device (100), the entire area may be changed, but only a part of the area (1) may be changed. In particular, for content such as a menu, only a part of the area (1) may be changed between the previous content (e.g., first content (A)) and the new content (e.g., second content (B)), such as changing some menus among the menus included in the menu to different menus, changing the prices of some menus, or overlapping a UI indicating sold-out on some menus (it may be updated only partially from the previous content).

[0080] According to the embodiment, when the display device (100) updates the display panel (110) by applying an electric field to all the microcapsules included in the display panel (110) to provide a second content in which only a part area (1) of the first content has been changed, a flickering phenomenon occurs in the remaining area excluding the part area (1) due to the application of the electric field, and there was a problem that a significant amount of time was consumed to update all the microcapsules included in the display panel (110).

[0081] A display device (100) according to an embodiment of the present disclosure may update only the changed portion (1) rather than the entire area of ​​the display panel (110) in order to provide a second content (B) in which a portion (1) of the first content (A) is changed.

[0082] Referring to FIG. 3, the display device (100) displays a first content (A), and while displaying the first content (A), if it acquires (or receives) a second content (B) in which a portion of the first content (A) has been changed, it can update the portion of the first content (1) and display the second content (B).

[0083] According to the embodiment, the display device (100) updates only a portion of the area (1) that has changed between the previous content (e.g., first content (A)) and the new content (e.g., second content (B)), and maintains (or does not update) the remaining area, thereby preventing unnecessary flickering in the remaining area. In addition, since only a portion of the area (1) is updated rather than the entire area of ​​the display panel (110), waste of time and power can be reduced.

[0084] According to an embodiment, the flickering phenomenon occurring in the electrophoretic display device may be an inherent phenomenon that occurs during the process of refreshing the display panel (110) to provide content (e.g., first content (A), second content (B), etc.). For example, the flickering phenomenon may occur during the process in which the display device (100) aligns each of the black particles or white particles contained in the microcapsules to correspond to the new content (e.g., second content (B)) in order to provide new content.

[0085] Additionally, if the display device (100) provides previous content (e.g., first content (A)) for a long time, each of the black particles or white particles contained in the microcapsules may become fixed in their current positions, causing a ghosting phenomenon. According to an embodiment, to prevent the occurrence of a ghosting phenomenon, the display device (100) aligns each of the black particles or white particles contained in the microcapsules to their initial positions and then aligns them to correspond to new content (e.g., second content (B)), and a blinking phenomenon may occur while each of the black particles or white particles is being aligned.

[0086] According to the embodiment, if a flickering phenomenon occurs in the entire area of ​​the display panel (110), the quality of the user experience is degraded, and there was a problem in that a flickering phenomenon occurred unnecessarily in the remaining area excluding the part area (1) that was changed between the previous content (e.g., first content (A)) and the new content (e.g., second content (B)).

[0087] A display device (100) according to an embodiment of the present disclosure updates a portion of the area (1) that has been changed between the first content (A) and the second content (B) to provide new content, for example, a second content (B), so that a flickering phenomenon may occur only in the portion of the area (1) and not in the remaining area.

[0088] For example, the display device (100) can receive coordinate information and a second content (B). According to an embodiment, the display device (100) can identify a portion of the area (1) that has changed between the first content (A) and the second content (B) based on the coordinate information.

[0089] According to an embodiment, the display device (100) identifies a portion area (1) corresponding to coordinate information in the first content (A) currently being displayed by the display device (100), and can display the second content (B) by updating the portion area (1) to correspond to the second content (B).

[0090] According to the embodiment, if the display device (100) provides the second content (B) by updating only a portion of the area (1), a boundary line may occur between the newly updated portion of the area (1) and the remaining area that is not updated on the second content (B) provided by the display device (100).

[0091] For example, as illustrated in FIG. 3, even if the background color of a part area (1) and the remaining area are the same on the second content (B) provided by the display device (100), the particles contained in the microcapsules corresponding to the part area (1) (e.g., black, white particles) and the particles contained in the microcapsules corresponding to the remaining area (e.g., black, white particles) are not aligned simultaneously, so there is a fine difference in the arrangement state (or alignment state) between the particles (e.g., inconsistency in the arrangement state between the particles), and the fine difference may cause a boundary line. In addition, a residual image phenomenon occurs in the remaining area, causing a fine color difference between the newly updated part area (1) and the unupdated remaining area (or a contrast occurs between the part area (1) and the remaining area), and the color difference may cause a boundary line.

[0092] FIG. 4 is a drawing illustrating a display device that sequentially updates pixels adjacent to a portion of a region according to an embodiment of the present disclosure.

[0093] Referring to FIG. 4, a display device (100) according to an embodiment of the present disclosure provides a second content (B) by updating a portion area (1) in a first content (A), and can update the remaining area (2) excluding the portion area (1) to remove a boundary line that occurs between the portion area (1) and the remaining area (2) on the second content (B).

[0094] According to an embodiment, the display device (100) may not provide the second content (B) by updating the entire area of ​​the display panel (110), but may provide the second content (B) by updating only the part area (1) that has been changed from the first content (A), and then update the remaining area (2) to remove the boundary line (or, the difference between the part area (1) and the remaining area (2)) that occurred between the part area (1) and the remaining area (2).

[0095] According to an embodiment, the display device (100) may simultaneously update a plurality of pixels corresponding to the remaining area (2), or sequentially update a plurality of pixels corresponding to the remaining area (2).

[0096] For example, the display device (100) can identify a portion of the region (1) based on coordinate information and sequentially update the pixels adjacent to the portion of the region (1) among the multiple pixels included in the remaining region (2).

[0097] For example, the display device (100) can provide a second content (B) by updating pixels corresponding to a portion of the area (1) among a plurality of pixels included in the display panel (110). Subsequently, the display device (100) can preferentially update pixels adjacent to at least one of the up, down, left, and right directions from the portion of the area (1) among pixels corresponding to the remaining area (2).

[0098] According to an embodiment, as illustrated in FIG. 4, the display device (100) can update a plurality of pixels included in the remaining area (2) by sequentially updating the pixels corresponding to the remaining area (2) in at least one of the up, down, left, and right directions, starting from the pixel closest to the partial area (1) and extending to the pixels furthest from the partial area (1) (e.g., pixels located at the edge of the display panel (110)) at a preset time interval (e.g., 5 sec). According to an embodiment, the preset time interval can be varied in various ways depending on user settings, settings via a server (200) providing content (e.g., first content, second content, etc.), settings based on firmware distributed by the manufacturer of the display device (100), etc.

[0099] According to the embodiment, the display device (100) updates only a part area (1) and does not update the remaining area (2), but updates the part area (1) to display the second content (B) and then updates the remaining area (2), so that the problem of causing flickering in the entire area to lower the quality of the user experience or taking a long time to provide the second content (B) can be prevented (see FIG. 3).

[0100] According to an embodiment, the display device (100) may update the remaining area (2) following the update of the partial area (1) in order to remove a boundary line (or contrast) that occurs between the partial area (1) and the remaining area (2) (see FIG. 4). For example, the display device (100) may update multiple pixels included in the remaining area (2) simultaneously, or may update multiple pixels included in the remaining area (2) sequentially from pixels adjacent to the partial area (1) to pixels far away.

[0101] According to an embodiment, if the display device (100) updates each of the plurality of microcapsules included in the display panel (110) and rearranges the positions of the color particles included in each of the plurality of microcapsules, the display device (100) can prevent the occurrence of afterimages while displaying new content (e.g., second content (B)) and can also remove boundary lines.

[0102] FIG. 5 is a drawing illustrating a display device that controls a display panel including a plurality of modules according to an embodiment of the present disclosure to display a second content.

[0103] According to an embodiment, the display panel (110) may include a plurality of modules (110-1, ..., 110-20).

[0104] In FIG. 5, for convenience of explanation, it is assumed that the display panel (110) includes a first module (110-1) to a 20th module (110-20), but it is not limited thereto.

[0105] According to an embodiment, the display device (100) receives (or acquires) coordinate information and a second content, and can identify a portion of the changed area between the first content (A) and the second content (B) based on the coordinate information.

[0106] According to an embodiment, the display device (100) can identify at least one module including some area of ​​a plurality of modules (110-1, ..., 110-20).

[0107] According to an embodiment, the display device (100) can display a second content (B) by updating a first plurality of pixels included in at least one module that includes a portion of the area.

[0108] According to an embodiment, the display device (100) can update the first plurality of pixels included in at least one module to display the second content (B), and then update the second plurality of pixels included in each of the remaining modules excluding at least one module among the plurality of modules (110-1, ..., 110-20).

[0109] Referring to FIG. 5, the display device (100) can identify a ninth module (110-9) and a tenth module (110-10) that include a portion of a changed area between a first content (A) and a second content (B) among a plurality of modules (110-1, ..., 110-20).

[0110] According to an embodiment, the display device (100) can update the pixels included in the ninth module (110-9) and the pixels included in the tenth module (110-10) to change a part of the first content (A) to correspond to the second content (B).

[0111] According to an embodiment, as illustrated in FIG. 5, there is a fine difference in the arrangement (or alignment) between the particles of microcapsules (e.g., black, white particles) included in the ninth module (110-9) and the tenth module (110-10) and the particles of microcapsules (e.g., black, white particles) included in the remaining modules (e.g., inconsistency in the arrangement of particles), and the fine difference can cause a boundary line.

[0112] According to an embodiment, the display device (100) can update the pixels included in the ninth module (110-9) and the pixels included in the tenth module (110-10) after updating the pixels included in each of the remaining modules (e.g., the first module (110-1) to the eighth module (110-8), the eleventh module (110-11) to the twenty-th module (110-20)).

[0113] According to an embodiment, the display device (100) may update the remaining modules (e.g., the first module (110-1) to the eighth module (110-8), the eleventh module (110-11) to the twentyth module (110-20)) simultaneously, or the remaining modules may be updated sequentially.

[0114] For example, as illustrated in FIG. 5, the display device (100) can update the pixels included in each of the third module (110-3) to fifth module (110-5), eighth module (110-8), and thirteenth module (110-13) to fifteenth module (110-15) that are adjacent to the ninth module (110-9) and the tenth module (110-10) in the up, down, left, right, and diagonal directions.

[0115] For example, the display device (100) can update the pixels included in each of the 3rd module (110-3) to 5th module (110-5), 8th module (110-8), and 13th module (110-13) to 15th module (110-15) after a preset time has elapsed (e.g., 5 sec) after updating the 9th module (110-9) and the 10th module (110-10). According to the embodiment, the preset time interval can be varied in various ways depending on user settings, settings via a server (200) providing content (e.g., 1st content, 2nd content, etc.), settings based on firmware distributed by the manufacturer of the display device (100), etc.

[0116] According to an embodiment, the display device (100) can update the third module (110-3) to the fifth module (110-5), the eighth module (110-8), and the thirteenth module (110-13) to the fifteenth module (110-15) to remove the boundary line between the ninth module (110-9) and the tenth module (110-10) which include a portion of the area, and the third module (110-3) to the fifth module (110-5), the eighth module (110-8), and the thirteenth module (110-13) to the fifteenth module (110-15) adjacent to the ninth module (110-9) and the tenth module (110-10).

[0117] FIG. 6 is a drawing illustrating a display device that sequentially updates a plurality of modules according to an embodiment of the present disclosure.

[0118] Referring to FIGS. 5 and 6, the display device (100) can sequentially update the remaining modules (e.g., the first module (110-1) to the eighth module (110-8), the eleventh module (110-11) to the twenty-th module (110-20)) at preset time intervals.

[0119] For example, after the display device (100) updates the third modules (110-3) to fifth modules (110-5), eighth module (110-8), and thirteenth modules (110-13) to thfifth modules (110-15) adjacent to the ninth module (110-9) and tenth module (110-10) which include some areas in the up, down, left, right, and diagonal directions, when a preset time has elapsed (e.g., 5 sec), the second modules (110-2), seventh modules (110-7), twelfth modules (110-12), and seventeenth modules (110-17) to twenty modules adjacent to the third modules (110-3) to fifth modules (110-5), eighth modules (110-8), and thirteenth modules (110-13) to thfifth modules (110-15) in the up, down, left, right, and diagonal directions are updated. Module (110-20) can be updated.

[0120] Subsequently, when a preset time elapses (e.g., 5 sec), the display device (100) can update the first module (110-1), sixth module (110-6), eleventh module (110-11), and sixteenth module (110-16) adjacent to the second module (110-2), seventh module (110-7), twelfth module (110-12), twelfth module (110-17) through twenty modules (110-20) in the up, down, left, right, and diagonal directions.

[0121] According to an embodiment, the display device (100) can sequentially update the remaining modules (e.g., the first module (110-1) to the eighth module (110-8), the eleventh module (110-11) to the twentieth module (110-20)) at preset time intervals to update a plurality of modules (110-1, ..., 110-20) constituting the display panel (110), and prevent the occurrence of a boundary line within the screen while displaying the second content (B) (or, remove the boundary line).

[0122] FIG. 7 is a drawing illustrating a color circle according to an embodiment of the present disclosure.

[0123] Figure 7 illustrates an example of a color wheel, in which colors are arranged in a ring shape to represent changes in color.

[0124] Referring to the 10-color wheel shown in Fig. 7, the 10 colors are arranged in a ring shape to show the variation of the 10 colors, and the mixing relationship and contrast (or complementary color) relationship between the colors are shown.

[0125] For example, the 10-color wheel includes red, yellow, green, blue, and purple, and may include yellow-red (a mixture of red and yellow between red and yellow), green-yellow (a mixture of yellow and green between yellow and green), blue-green (a mixture of green and blue between green and blue), purple-blue (a mixture of blue and purple between blue and purple), and red-purple (a mixture of purple and red between purple and red). For example, red and blue-green, which are opposite each other on the 10-color wheel, may be in a contrast (or complementary) relationship.

[0126] According to an embodiment, each of the plurality of microcapsules included in the display device (100) may include various colored particles such as green particles, blue particles, yellow particles, and red particles in addition to black particles and white particles. For convenience of explanation, the description will assume a case where each of the plurality of microcapsules constituting the display panel (110) includes black particles, white particles, green particles, blue particles, yellow particles, and red particles.

[0127] According to an embodiment, the display device (100) can express colors included in content (e.g., first content (A), second content (B)) by combining (or mixing) various color particles.

[0128] For example, the display device (100) can sequentially arrange (or move) each of a plurality of color particles according to a preset order. For example, to display content, the display device (100) can sequentially arrange a plurality of color particles in the order of black particles -> white particles -> green particles -> blue particles -> yellow particles -> red particles to display content. For example, to change a portion of previous content (e.g., first content (A)), the display device (100) can sequentially arrange a plurality of color particles contained in microcapsules corresponding to a portion of the portion according to a preset order to change (or update) a portion of the portion to correspond to new content (e.g., second content (B)).

[0129] For example, when a display device (100) sequentially arranges a plurality of color particles according to a preset order, the display device (100) may arrange a third color particle (e.g., yellow particle) that is close to a contrast (or complementary) relationship, rather than arranging a second color particle (e.g., red particle) adjacent to the first color particle according to a color wheel after arranging a first color particle (e.g., blue particle).

[0130] According to the embodiment, if the display device (100) aligns a third color particle that is close to the contrast relationship after aligning a first color particle, the quality of the user experience is degraded due to the sudden color change, and it may cause the illusion that the display panel (110) has malfunctioned.

[0131] According to an embodiment, the display device (100) may sequentially align a plurality of color particles according to a preset order, but the display panel (110) may be controlled to align a second color particle adjacent to the first color particle after aligning the first color particle based on a color wheel. A detailed explanation thereof will be provided with reference to FIGS. 8 and 9.

[0132] FIG. 8 is a drawing illustrating colors corresponding to some areas according to an embodiment of the present disclosure.

[0133] According to an embodiment, when the display device (100) receives coordinate information and a second content (B), it can identify a part of the first content (A) based on the coordinate information.

[0134] According to an embodiment, the display device (100) can identify a first color (e.g., green) corresponding to a part area of ​​the first content (A) among a plurality of color particles included in the display panel (110).

[0135] For example, the display device (100) can identify the representative color (or average color) of a part of the first content (A) as the first color based on the average color coordinates of pixels included in a part of the first content (A).

[0136] According to an embodiment, the display device (100) can identify a second color (e.g., yellow) corresponding to a part of the changed area in the second content (B).

[0137] For example, the display device (100) can identify the representative color (or average color) of a changed portion of the second content (B) as the second color based on the average color coordinates of the pixels included in a changed portion of the second content (B).

[0138] According to an embodiment, the display device (100) can arrange colors that can be provided through the display panel (110) from a first color to a second color based on a color wheel. A detailed explanation thereof will be provided with reference to FIG. 9.

[0139] FIG. 9 is a drawing illustrating a display device that arranges colors that can be provided through a display panel from a first color to a second color according to an embodiment of the present disclosure based on a color wheel.

[0140] Referring to FIG. 8, the display device (100) can identify that a part of the first content (A) corresponds to a first color, and that a part of the changed content (B) corresponds to a second color.

[0141] According to an embodiment, the display device (100) can arrange black particles and white particles last after arranging the first to fourth colors based on a color wheel when the first color and the second color are adjacent.

[0142] For example, the display device (100) can identify that a part of the first content (A) corresponds to green, and that a part of the changed part of the second content (B) corresponds to yellow.

[0143] As illustrated in FIG. 9, since green and yellow are adjacent, the display device (100) can arrange the remaining colors, such as green, blue, red, and yellow, excluding black and white, among the colors that can be provided through the display panel (110), from green to yellow.

[0144] For example, the display device (100) can arrange green based on a color wheel, arrange blue adjacent to green, arrange red adjacent to blue, and then arrange yellow. Subsequently, the display device (100) can arrange white and black (or black and white) last.

[0145] According to an embodiment, the display device (100) can sequentially arrange (or position) a plurality of color particles in the order of green particles -> blue particles -> red particles -> yellow particles -> white particles -> black particles (or black particles -> white particles) during the process of updating a part area of ​​the first content (A) to correspond to the second content (B).

[0146] However, this is an example for the convenience of explanation and is not limited thereto.

[0147] According to an embodiment, the display device (100) may arrange black particles, white particles, a third color, and a fourth color between the first color and the second color, based on a color wheel, if the first color and the second color are not adjacent, fix the first color first and fix the second color last.

[0148] For example, the display device (100) can identify that a part of the first content (A) corresponds to green, and that a part of the changed part of the second content (B) corresponds to red.

[0149] As illustrated in FIG. 9, since green and red are not adjacent, the display device (100) can arrange colors that can be provided through the display panel (110), from green to red.

[0150] For example, the display device (100) can arrange green based on a color wheel and arrange blue adjacent to green. Then, the display device (100) can exclude red adjacent to blue among the multiple color particles because it must be arranged last, exclude yellow because it is close to a contrast (or complementary) relationship with blue, and arrange white and black (or black and white). Then, the display device (100) can arrange red last after arranging yellow.

[0151] According to an embodiment, the display device (100) can sequentially arrange (or position) a plurality of color particles in the order of green particles -> blue particles -> white particles -> black particles (or, black particles -> white particles) -> yellow particles -> red particles during the process of updating a part area of ​​the first content (A) to correspond to the second content (B).

[0152] According to an embodiment, the display device (100) minimizes the occurrence of sudden color changes during the process of updating the display panel (110) to change some areas, thereby improving the quality of the user experience and preventing the illusion that the display panel (110) is malfunctioning.

[0153] Returning to Fig. 2, the display device (100) may further include a communication interface.

[0154] The communication interface can input and output various types of data. For example, the communication interface can transmit and receive various types of data with external devices (e.g., source devices), external storage media (e.g., USB memory), and external servers (e.g., web hard drives) through communication methods such as AP-based Wi-Fi (Wi-Fi, Wireless LAN network), Bluetooth, Zigbee, wired / wireless LAN (Local Area Network), WAN (Wide Area Network), Ethernet, IEEE 1394, HDMI (High-Definition Multimedia Interface), USB (Universal Serial Bus), MHL (Mobile High-Definition Link), AES / EBU (Audio Engineering Society / European Broadcasting Union), Optical, and Coaxial.

[0155] According to one example, the communication interface may include a Bluetooth Low Energy (BLE) module. BLE refers to Bluetooth technology capable of transmitting and receiving low-power, low-capacity data in the 2.4 GHz frequency band with a range of about 10 m. However, it is not limited thereto, and the communication interface may also include a Wi-Fi communication module. For example, the communication interface may include at least one of a Bluetooth Low Energy (BLE) module or a Wi-Fi communication module.
