[0057] An embodiment of the present disclosure will be described in more detail with reference to the attached drawings below.

[0058] FIG. 1 is a drawing for explaining an electronic device (100) that displays an image according to one embodiment.

[0059] Referring to FIG. 1, the electronic device (100) may be a device that displays an image. The electronic device (100) may be a display device that includes a panel for displaying an image.

[0060] The electronic device (100) can be connected to an external device (200). The electronic device (100) can receive an image or a control command from the external device (200).

[0061] The electronic device (100) can display an image received from an external device (200). The electronic device (100) can perform a control operation based on a control command received from the external device (200).

[0062] The electronic device (100) can operate in multiple modes. The electronic device (100) can operate in one of a first mode, a second mode, or a third mode. The first mode may be a normal mode, the second mode may be a power-saving mode, and the third mode may be a communication standby mode.

[0063] The third mode may be a power saving mode to save power by supplying power only to the preset modules.

[0064] The second mode may be a communication standby mode that additionally supplies power to modules performing communication functions in addition to the modules supplied in the power-saving mode. The communication standby mode may be described as a network standby mode, an external communication mode, etc.

[0065] The first mode may be a normal mode in which power can be supplied to all modules included in the electronic device (100). The normal mode may be a mode in which power is supplied to the main processor.

[0066] For example, the electronic device (100) may be e-Paper (electronic-Paper). The electronic device (100) may be described as electronic paper, an electronic book, an e-Paper display, an e-Paper device, an e-Paper apparatus, etc.

[0067] An electronic device (100) can display an image using electronic ink. The electronic ink can include colored particles (e.g., black and white particles). The electronic device (100) can display an image using microcapsules containing electronic ink. The electronic ink contained in the microcapsules can have particles of a first color (e.g., white) that are positively charged, and particles of a second color (e.g., black) that are negatively charged. The electronic device (100) can display an image by electrically controlling the microcapsules.

[0068] According to one embodiment, the electronic device (100) can display various colors using microcapsules and color filters including white particles and black particles.

[0069] The electronic device (100) can control the first color particles of electronic ink contained in the microcapsules to be positioned above the panel or the second color particles to be positioned above the panel by applying a voltage to the display module. An image can be displayed depending on which particle is displayed above.

[0070] The electronic device (100) can apply a voltage to place particles based on image pixel values. The operation of placing particles by applying a voltage can be performed in a normal mode.

[0071] When the particles are positioned by applying voltage, the electronic device (100) does not need to apply additional voltage to continue displaying the image. The electronic device (100) can change the normal mode to the power saving mode. While the image is displayed, the electronic device (100) can operate in the power saving mode. The electronic device (100) can apply voltage to some components even in the power saving mode. The electronic device (100) can update the image at preset intervals.

[0072] Image updating may include an operation of displaying the same image as the existing image once again. Image updating may include an operation of rearranging the arrangement of arranged particles. The electronic device (100) may initialize the arrangement of already arranged particles. The electronic device (100) may rearrange the arrangement of the initialized particles based on the image pixel values. Consequently, the electronic device (100) may display the same image by performing the image updating operation. Through the image updating operation, the electronic device (100) may prevent afterimages of the e-Paper. The preset time may be changed according to the user's settings.

[0073] The electronic device (100) may include one of an electrophoretic display, an electrowetting display, or an interferometric modulator display.

[0083] At least one processor (120) may control the display (140) to update the first image in the normal mode after a first time period when the normal mode is changed to the power saving mode based on a first user input. The expression "changing to the mode" may be described as "operating in the mode."

[0084] At least one processor (120) can receive a first user input.

[0085] The first user input may represent a user command to change from normal mode to power-saving mode. For example, the first user input may include an input in which the user presses a physical button on the electronic device (100). For example, the first user input may be received through an application on an external device (200). Additional information related to the user input is described in FIGS. 4 to 6 .

[0086] When a first user input is received, at least one processor (120) can change from a normal mode to a power saving mode. At least one processor (120) can identify whether a first time has arrived (or elapsed) in the power saving mode.

[0092] The second user input may represent a user command to change from normal mode to communication standby mode. For example, the second user input may include an input in which the user presses a physical button on the electronic device (100). For example, the second user input may be received via an application on an external device (200). Additional information related to the user input is described in FIGS. 4 to 6 .

[0093] When a second user input is received, at least one processor (120) can change from a normal mode to a communication standby mode. At least one processor (120) can identify whether a second time has arrived (or elapsed) in the communication standby mode.

[0094] When an event is identified that causes the second time to arrive (or elapse) in the communication standby mode, at least one processor (120) can change the communication standby mode to the normal mode.

[0095] At least one processor (120) can control the display (140) to update the first image in the normal mode. Once the first image is updated, at least one processor (120) can change from the normal mode to the communication standby mode.

[0096] Details regarding an embodiment of changing from communication standby mode to normal mode are described in FIG. 14.

[0097] The first time may be described as the first critical time, the first period, the first preset time, etc.

[0098] The second time may be described as the second critical time, the second period, the second preset time, etc.

[0099] For example, the first time and the second time may be different. The first time calculated (or computed) in power saving mode may be different from the second time calculated (or computed) in communication standby mode.

[0100] For example, the first time and the second time may be the same. The first time calculated (or computed) in power-saving mode and the second time calculated (or computed) in communication standby mode may be the same. The second time may be described as the first time.

[0101] The first and second times described in connection with the description of the multiple drawings below may not all refer to the same concept. They may be intended to distinguish different times in each embodiment. The ordinal numbers described for the first and second times may change. For times applied in different embodiments, the first time may be described as the third time, and the second time as the fourth time. In the description below, for the convenience of each description, the first time concept appearing in each embodiment may be described as the first time, and the second time concept may be described as the second time.

[0102] If the time concepts are identical, either the first or second time expression can be maintained. Even if the embodiments differ slightly, the same ordinal time expression can be described. The first time expression can be maintained for the time concept applied in power-saving mode, and the second time expression can be maintained for the time concept applied in communication standby mode.

[0104] The power saving mode may be a mode in which power is not supplied to the communication interface (130). The communication standby mode may be a mode in which power is supplied to the communication interface (130). In the power saving mode, information may not be received from the external device (200). In the communication standby mode, information may be received from the external device (200). In the communication standby mode, control commands received from the external device (200) cannot be directly executed.

[0105] The display (140) may include an e-Paper display. The display (140) may include electronic ink containing charged particles.
