Description

Electronic device for diagnosing power failure of a display and method of operation thereof

[0001] The present disclosure relates to a technique for diagnosing a power failure of a display in an electronic device.

[0002] As mobile devices become more functional, the types of malfunctions they can cause are also becoming more diverse. Among these various types of malfunctions, those occurring in the display can be relatively inconvenient because they are intuitively recognizable to users. In smartphones, where the display occupies most of the surface area, they can cause operational inconveniences in addition to visual ones.

[0003] Display defects can be caused by a variety of factors, including material defects, external impacts, and progressive defects. Progressive defects can be caused by foreign substances or corrosion inside the mobile device.

[0004] In cases of progressive defects, users may be able to visually detect the display defect while using the mobile device.

[0005] However, if there is a problem with the display power during the progress, it is not directly visible on the display screen, making it difficult for the user to check it with the naked eye. If left untreated, it may have a negative effect not only on the display but also on other components.

[0006] The present disclosure provides an electronic device and an operating method thereof for detecting a defect in a display module in advance even while the display screen is operating normally.

[0007] An electronic device according to one embodiment may include a display module, a first power management module for controlling first voltage power and second voltage power supplied to the display module, and a regulator power supply, and may include a second power management module for controlling power supplied to at least one processor. The at least one processor may, when the first voltage power supply is turned on, switch a first mode in which the regulator power supply is operated to a second mode in which the regulator power supply operates as a bypass, receive an interrupt generated based on a first voltage output by the first voltage power supply, and determine an abnormality in the display module based on the interrupt.

[0008] In an operating method of an electronic device according to one embodiment, the electronic device may include a display module, a first power management module, a second power management module, and at least one processor. The operating method may include an operation of switching a first mode in which a regulator power of the second power management module is driven to a second mode in which the regulator power operates as a bypass when a first voltage power controlled by the first power management module is turned on, an operation of receiving an interrupt generated based on a first voltage output by the first voltage power supply by at least one processor, and an operation of determining an abnormality of the display module based on the interrupt.

[0061] According to one embodiment, the first power management module (188-1) may include or be connected to a connector (1780). The connector (1780) may be composed of a plurality of pins, each of which may be connected to the display module (160) through different wiring. For example, the connector (1780) may be composed of 60 pins, but may also be composed of fewer or more pins than 60 pins depending on the wiring design between the first power management module (188-1) and the display module (160).

[0062] Among the power supplies shown, the power supply having the highest voltage is EVAVDD, and for example, EVAVDD can provide a voltage of about 7.2 V to the display module (160). VCI, which is a power supply adjacent to ELAVDD, is a power supply supplied to the DDI and can provide a voltage of about 3.0 V to the display module (160). At this time, ELAVDD and VCI are closest in terms of relative position, and a problem may occur in the resistive material near the wiring that transmits the voltage of ELAVDD due to the high voltage characteristic of ELAVDD. Therefore, a short circuit may occur between ELAVDD and VCI. Meanwhile, even if a short circuit occurs between ELAVDD and VCI, it is not visually confirmed in the image provided on the display screen, but if the short circuit state is maintained and a voltage that does not meet the rated specification is continuously applied to each element included in the display module (160), other components in addition to the display module (160) may be damaged.

[0063] The above describes a short circuit that occurs between ELAVDD and VCI, but it is not necessarily limited to ELAVDD and VCI. Since ELAVDD has the highest voltage, a short circuit can also occur in other power wiring if it is located close to ELAVDD or electrically connected to it via wiring.

[0064] Meanwhile, the first power management module (188-1) can operate according to the first mode or the second mode.

[0065] The first mode refers to a state in which a user is using an application of an electronic device (101), and the processor (120), display module (160), and network are operating normally. For example, in the first mode, the first power management module (188-1) may operate in Buck mode to supply rated voltage to the display module (160).

[0066] The second mode corresponds to a mode for reducing battery consumption by delaying the operation of the processor (120), the operation of the display module (160), and the operation of the network when the user does not use the electronic device (101) for a certain period of time. For example, the electronic device (101) operates in the second mode, Doze mode, when a set period of time has elapsed while the screen is turned off while not being charged. When the electronic device (101) enters the second mode, the first power management module (188-1) for managing the power supplied to the display module (160) and / or the second power management module (188-2) for managing the power supplied to the processor (120) may operate according to the Doze Mode in order to reduce power consumption due to the operation of the processor (120) and / or the display module (160).

[0067] Fig. 5 illustrates a control block diagram when a short circuit does not occur, and Fig. 6 is a flowchart of an operating method of an electronic device in a state according to Fig. 5.

[0068] According to one embodiment, the first power management module (188-1) supplies a first voltage to the display module (160, FIG. 4) in the first mode, and the second voltage power supply supplies a second voltage lower than the first voltage to the display module (160, FIG. 4). The battery (189) supplies power to the display module (160), the first power management module (188-1) managing power to be supplied to the display module (160), and the second power management module (188-2) managing power supplied to the processor (120). In the first mode, the second power management module (188-2) operates in Buck mode to ensure that the application is executed normally.

[0069] For example, when the first voltage power supply is ELAVDD and the second voltage power supply is VCI, ELAVDD can supply a voltage of about 7.2 V to the display module (160) to operate the regulator of the display module (160), and VCI can supply a voltage of about 3 V to the display driver IC (DDI) (230, see FIG. 2) of the display module (160).

[0070] Referring to FIG. 6, an electronic device (101) according to one embodiment causes a first power management module (188-2) to enter a first mode (601).

[0071] In the first mode, the first voltage power supply (501) supplies a first voltage that does not exceed the absolute maximum rating (AMR) to the display module (160). In the second mode, the second voltage power supply (502) supplies a second voltage that does not exceed the absolute maximum rating to the display module (160). The first voltage corresponds to a voltage higher than the second voltage.

[0072] An electronic device (101) according to one embodiment can detect a first voltage output from a first voltage power source (501) (603).

[0073] An electronic device (101) according to one embodiment determines (605) whether a first voltage output from a first voltage power source (501) is higher than a reference voltage. The reference voltage is a value that is compared to determine whether a voltage drop has occurred in the first voltage due to a short circuit, and is lower than the maximum rated voltage and refers to a voltage level when the first voltage power source normally supplies power.

[0074] According to step 605, if the first voltage is equal to the reference voltage or lower than the maximum rated voltage, the electronic device (101) according to one embodiment determines that a short circuit has not occurred.

[0075] After this, the electronic device (101) according to one embodiment does not generate an interrupt (607). The interrupt may correspond to one of the routine operations processed for short circuit protection (SCP) provided by the first power management module (188-1).

[0076] Figure 7 shows a control block diagram when a short occurs in the first mode.

[0077] Unlike FIG. 5, when a short circuit occurs between the first voltage power source (501) and the second voltage power source (502), the first voltage supplied from the first voltage power source (501) can be applied to the output terminal side of the second voltage power source (502).

[0078] For example, when the first voltage power supply (501) is ELAVDD, it outputs a voltage of about 7.2 V. If a short circuit occurs, the voltage of 7.2 V may also be supplied to an element corresponding to the second voltage power supply (502). As mentioned above, ELAVDD is a power supply that supplies the highest voltage in the relationship between the display module (160) and the first power management module (188-1), and if the voltage supplied by ELAVDD is 7.2 V to an element other than the element corresponding to ELAVDD, the voltage may exceed the maximum rated voltage, which may cause damage to the element.

[0079] In addition, in a short state, the first voltage supplied from the first voltage power source (501) may be applied to the second power management module (188-2) due to the diode characteristics of the second voltage power source (502), and as a result, the second power management module (188-2) may also be adversely affected.

[0080] Even if a short circuit occurs in the electronic device (101), a certain level of voltage is supplied to each element of the display module (160), although it is not at the rated voltage, so the user cannot check the power failure on the display screen.

[0081] Fig. 8 is a diagram for explaining the voltage drop when a short circuit occurs in the second mode. Fig. 9 is a flowchart of an operating method of an electronic device in a state according to Fig. 8.

[0082] An electronic device (101) according to one embodiment can switch the power management module (188, see FIG. 1) from a first mode to a second mode. The first mode is a state in which a user is using an application of the electronic device (101), and power may be supplied in a manner determined for the processor (120), the display module (160), and the network to generally operate. The second mode may correspond to a state for minimizing consumption of the battery (189) when the user does not use the electronic device (101) for a certain period of time. That is, the electronic device (101) according to one embodiment can switch the power management module (188) from the first mode to the second mode even when the user is using an application.

[0083] According to one embodiment, the electronic device (101) can control the second power management module (188-2) so that the regulator power (Vreg) of the second power management module (188-2) operates in a bypass mode in the second mode. When the regulator power operates in the bypass mode, the power supplied from the battery (189) can pass through the second power management module (188-2) as is and be applied between the second power management module (188-2) and the second voltage power source (502). For example, if the voltage output by the battery (189) in the second mode is 4 V, the voltage of 4 V can pass through the second power management module (188-2) as is and be applied between the second power management module (188-2) and the second voltage power source (502). At this time, the voltage of 4 V that passes through the second power management module (188-2) is also applied to the second voltage power supply (502), and a voltage lower than 4 V is also transmitted to the output terminal of the first voltage power supply (501) due to the diode's own resistance. That is, a voltage drop occurs at the output terminal of the first voltage power supply (501).

[0084] According to one embodiment, the first power management module (188-1) may generate an interrupt, which is a routine operation processed for short circuit protection (SCP). According to one embodiment, the first power management module (188-1) may generate an interrupt when it detects a voltage lower than a reference voltage at the output terminal of the first voltage power source (501).

[0085] Referring to FIG. 9, an electronic device (101) according to one embodiment causes a first power management module (188-2) to enter a second mode from a first mode (901). When the electronic device (101) according to one embodiment is in the second mode, the regulator power supply (Vreg) of the second power management module (188-2) may operate in a bypass mode. Accordingly, power supplied from the battery (189) may pass through the second power management module (188-2) as is and be applied between the second power management module (188-2) and the second voltage power supply (502).

[0086] An electronic device (101) according to one embodiment can detect a first voltage output from a first voltage power source (501) (903).

[0087] Unlike the cases of FIGS. 5 and 6, in the embodiment according to FIG. 9, a short circuit may occur between the first voltage power supply (501) and the second voltage power supply (502), resulting in a voltage drop at the output terminal of the first power supply voltage (501).

[0088] An electronic device (101) according to one embodiment determines whether a first voltage output from a first voltage power source (501) is lower than a reference voltage (905). In a short-circuit state, the first voltage may be lower than a voltage that is normally output. For example, when the regulator power source (Vreg) operates as a bypass, the voltage output from the battery (189) is transmitted to the output terminal of the first voltage power source (501) by passing through the second voltage power source (502). At this time, the transmitted voltage lowers the first voltage supplied by the first voltage power source (501).

[0089] According to step 905, if the first voltage is lower than the reference voltage, the electronic device (101) according to one embodiment determines that a short has occurred.

[0090] Thereafter, the electronic device (101) according to one embodiment generates an interrupt (607). The first power management module (188-1) according to one embodiment transmits the interrupt to the processor (160, FIG. 1).

[0091] Fig. 10 is a flowchart of an operating method of an electronic device according to one embodiment.

[0092] An electronic device (101) according to one embodiment initiates a display power diagnosis (diagnostic mode) (1001). The diagnostic mode may be performed at the user's command or automatically. The diagnostic mode may be performed automatically when various conditions are met. The various conditions are described in detail with reference to FIG. 11 below.

[0093] An electronic device (101) according to one embodiment can turn on a first voltage power source (501) (1003). The processor (160) can control a first power management module (188-1) to turn on the first voltage power source (501). The reason why the first voltage power source (501) is turned on is because an interrupt generation condition is a voltage drop occurring at an output terminal of the first voltage power source (501).

[0094] An electronic device (101) according to one embodiment can cause a second power management module (188-2) to enter a second mode (1005).

[0095] An electronic device (101) according to one embodiment controls a second power management module (188-2) to operate the regulator power supply (Vreg) in a bypass mode (1007).

[0096] An electronic device (101) according to one embodiment detects (1009) a first voltage of a first voltage power source (501). The first voltage generated at the output terminal of the first voltage power source (501) may decrease due to the occurrence of a short circuit.

[0097] If the first voltage is lower than the reference voltage (1011), the first power management module (188-1) according to one embodiment generates an interrupt (1013). Then, the first power management module (188-1) according to one embodiment transmits the interrupt to the processor (160) (1015).

[0098] According to one embodiment, the processor (160) determines that there is a problem with the display power when receiving an interrupt (1017).

[0099] Meanwhile, if the first voltage is not less than the reference voltage and is close to the rated voltage, the first power management module (188-1) according to one embodiment does not generate an interrupt (1019).

[0100] If no interrupt occurs, the electronic device (101) according to one embodiment determines that there is no problem with the display power (1021).

[0101] The above describes an algorithm for detecting display power supply abnormalities based on voltage drops caused by short circuits and interrupts caused by voltage drops. Below, a method for an electronic device (101) to perform a diagnostic mode according to various conditions and, if a display power supply abnormality is detected as a result of the diagnostic mode, a method for the electronic device (101) to handle the situation will be described.

[0102] FIG. 11 is a flowchart of an operating method of an electronic device using various diagnostic modes according to one embodiment.

[0103] According to one embodiment, when the electronic device (101) is first operated (1101), the electronic device (101) records the usage time of the electronic device (101) from the time of operation (1103). Once a short circuit occurs, damage caused by the short circuit accumulates over time, so the electronic device (101) records the accumulated usage time from the time the user purchases the electronic device (101) and begins using it.

[0104] The predetermined time may be set differently for each region of the electronic device (101). The durability of the electronic device (101) may be affected by the temperature or humidity of a specific region. For example, if the region where the electronic device (101) is used is in a high temperature and high humidity environment, a short circuit may easily occur or damage to components due to a short circuit may occur relatively quickly.

[0105] If the recorded usage time exceeds a predetermined time (1105), the electronic device (101) automatically executes a diagnostic mode (1107). When the diagnostic mode is automatically executed, operations according to FIG. 10 may be performed.

[0106] An electronic device (101) according to one embodiment can perform a diagnostic mode by receiving a command requesting a diagnosis from a user (1113) even if the usage time does not exceed a predetermined time.

[0107] Additionally, the electronic device (101) according to one embodiment can automatically perform a diagnostic mode without receiving a command requesting a diagnosis from a user when an abnormal reboot occurs.

[0108] Additionally, the electronic device (101) according to one embodiment can automatically perform a diagnostic mode in response to receiving a command from a user to forcibly terminate the electronic device (101) and receiving a command from the user to reboot the electronic device (101).

[0109] Meanwhile, if the electronic device (101) according to one embodiment performs a diagnostic mode and detects an abnormality in the display power, it may provide a notification regarding the display power abnormality (1109). For example, the electronic device (101) may output a pop-up on the display screen to provide the user with a message indicating that additional diagnosis is required. Furthermore, in addition to providing the notification on the display screen, the electronic device (101) according to one embodiment may also provide the notification to an external electronic device (102, 104, or 108, see FIG. 1) via a wireless communication channel. For example, the electronic device (101) may control the communication module (190, see FIG. 1) to provide the notification to a wearable device (e.g., a smartwatch) connected using Bluetooth. Furthermore, for example, the electronic device (101) may control the communication module (190, see FIG. 1) to provide the notification to an external electronic device (104, see FIG. 1) linked to an Internet of Things platform. Additionally, when the electronic device (101) according to one embodiment performs a diagnostic mode and finds that there is an abnormality in the display power, it can execute a data cloud backup of all data stored in the electronic device (101) (1113).

[0110] An electronic device (101) according to one embodiment may automatically perform data cloud backup, and may provide a message to the user notifying of a display power failure and at the same time provide a message suggesting data cloud backup due to the display power failure.

[0111] An electronic device (101, FIG. 1) according to one embodiment may include a display module (160, FIGS. 1 to 4) and a first power management module (188-1, FIGS. 3 to 5, FIGS. 7 and 8) and a regulator power supply (Vreg, FIGS. 5, 7 and 8) that control a first voltage power supply (501, FIGS. 5, 7 and 8) and a second voltage power supply (502, FIGS. 5, 7 and 8) supplied to the display module (160, FIGS. 1 to 4), and a second power management module (188-2, FIGS. 5, 7 and 8) that controls a power supply to at least one processor (120, FIGS. 1 and 3). At least one processor (120, FIGS. 1 and 3) according to one embodiment can switch a first mode in which a regulator power supply (Vreg, FIGS. 5, 7 and 8) is being driven, to a second mode in which the regulator power supply (Vreg, FIGS. 5, 7 and 8) operates as a bypass, when a first voltage power supply (501, FIGS. 5, 7 and 8) is turned on. At least one processor (120, FIGS. 1 and 3) according to one embodiment can receive an interrupt generated based on a first voltage output by the first voltage power supply (501, FIGS. 5, 7 and 8). At least one processor (120, FIGS. 1 and 3) according to one embodiment can determine an abnormality of a display module (160, FIGS. 1 to 4) based on the interrupt.

[0112] An electronic device (101, FIG. 1) according to one embodiment may further include a connector (1780, FIG. 4) composed of a plurality of pins to electrically connect a display module (160) and a first power management module (188-1). A first voltage power source (501) and a second voltage power source (502) according to one embodiment may supply power to the display module (160) at positions of adjacent pins among the plurality of pins. A first power management module (188-2) according to one embodiment may generate an interrupt when a first voltage becomes lower than a reference voltage due to a short circuit occurring between the first voltage power source (501) and the second voltage power source (502).

[0113] At least one processor (120) according to one embodiment may receive an interrupt from the first power management module (188-1). The interrupt may be a short circuit protection (SCP) provided by the first power management module (188-1).

[0114] According to one embodiment, the first voltage power supply (501) may be an ELAVDD that provides a first voltage as an input power to a power generation circuit through a first power management module (188-1).

[0115] At least one processor (120) according to one embodiment, upon receiving an interrupt, determines that the power of the display module (160) is defective and controls the display module (160) to output power status information of the display module (160) to the screen.

[0116] An electronic device (101, FIG. 1) according to one embodiment may further include a memory (130, FIG. 1) operatively connected to at least one processor (120). The memory (130) according to one embodiment may store the time at which an interrupt occurred in a diagnostic mode for switching from a first mode to a second mode.

[0117] At least one processor (120) according to one embodiment may cause the memory (130) to record the usage time of the electronic device (101). At least one processor (120) according to one embodiment may automatically execute a diagnostic mode when the usage time exceeds a predetermined time.

[0118] At least one processor (120) according to one embodiment may execute a diagnostic mode upon receiving a command requesting a diagnosis from a user.

[0119] An electronic device (101, FIG. 1) according to one embodiment may further include a communication module (190, FIG. 1) that performs communication with an external device (102, 104, or 108 of FIG. 1) via a network. At least one processor (120) according to one embodiment may, upon receiving an interrupt, transmit data stored in a memory (130) to the external device (102, 104, or 108 of FIG. 1) via a network.

[0120] The predetermined time according to one embodiment may be set differently for each region of the electronic device (101).

[0121] In an operating method of an electronic device (101, FIG. 1) according to one embodiment, the electronic device (101) may include a display module (160, FIGS. 1 to 4), a first power management module (188-1, FIGS. 3 to 5, FIGS. 7 and 8), a second power management module (188-2, FIGS. 5, 7 and 8), and at least one processor (120, FIGS. 1 and 3). The operating method according to one embodiment may include an operation of switching a first mode in which a regulator power supply (Vreg, FIGS. 5, 7 and 8) of a second power management module (188-2, FIGS. 5, 7 and 8) is being driven, to a second mode in which the regulator power supply (Vreg) operates as a bypass, while a first voltage power supply (501, FIGS. 5, 7 and 8) controlled by the first power management module (188-1) is turned ON. An operating method according to one embodiment may include an operation in which at least one processor (120) receives an interrupt generated based on a first voltage output by a first voltage power supply (501). An operating method according to one embodiment may include an operation in which an abnormality of a display module (160) is determined based on the interrupt.

[0122] An electronic device (101, FIG. 1) according to one embodiment may further include a connector (1780, FIG. 4) composed of a plurality of pins to electrically connect a display module (160) and a first power management module (188-1).
