Patent Application
20210255773
Embodiments of the disclosure relate to a technology for securing a storage capacity of a memory.
As an information technology (IT) has been developed, service ranges to be provided to a user have been extensively increased in a display device. For example, the display device may provide, to a user, a movie, a drama, and an advertisement received over the Internet. In addition, to provide, to a user, a feeling similar to a reality space, the display device may output a 3D image, and the user may enjoy a game through the display device.
As various types of services may be provided to the user, and the size of the display device is increased, the number of applications executed at one time by the display device is increased. For example, an application to output a moving picture or an application to receive data from an external device may be simultaneously executed.
When several applications are simultaneously executed, the display device may terminate an unnecessary application to secure the storage capacity of the memory. However, some applications may be instantly re-executed as soon as the display device terminates the some applications. When the some applications are re-executed, the display device has to terminate the some applications again. Accordingly, data processing or calculation of the display device may be overloaded. In addition when some applications are executed, the storage capacity of the memory is not secured. Accordingly, a screen may be stopped.
Embodiments disclosed in the disclosure are to provide an electronic device to solve the above problems and to resolve the issues raised herein.
According to an embodiment of the disclosure, a display device may include a memory to store an application belonging to a first group executed without a trigger after execution-terminated, and an application belonging to a second group re-executed by a trigger after execution-terminated and a processor to measure a spare storage capacity indicating an amount of a spare space to store data by the memory, in which the processor may first terminate the application belonging to the second group rather than the application belonging to the first group, when selecting an application, which is to be terminated, of the application belonging to the first group and the application belonging to the second group, and when the spare storage capacity is equal to or less than a preset value.
According to an embodiment of the disclosure, a method of a display device may include measuring a spare storage capacity indicating an amount of a spare space to store data by a memory of the display device, determining whether an application, which is being executed in the display device, is an application belonging to a first group or an application belonging to a second group, when the spare storage capacity is equal to or less than a preset value, not terminating the application, which is being executed, when the application, which is being executed, is the application belonging to the first group, as a determination result, and terminating the application being executed, when the application, which is being executed, is the application belonging to the second group, as the determination result, and the application belonging to the first group may refer to an application which is re-executed without a trigger after execution-terminated, and the application belonging to the second group may refer to an application which is re-executed by a trigger after execution-terminated.
According to an embodiment of the disclosure, the display device may include a memory to store applications, an executing unit to classify the applications into a first group application re-executed without a trigger after execution-terminated, and a second group application re-executed by a trigger after execution-terminated, a measuring unit to measure a storage capacity indicating an amount of data to be stored in the memory, and a managing unit to determine whether an application, which is being executed, is included in the first group application or the second group application, when the storage capacity is equal to or less than a preset value, not to terminate the application being executed when the application belongs to the first group application as the determination result, and to terminate the application being executed when the application belongs to the second group application as the determination result.
According to embodiments disclosed herein, the storage capacity of the memory may be secured. According to embodiments of the disclosure, the driving performance of the processor may be improved.
Besides, a variety of effects directly or indirectly understood through the disclosure may be provided.
Hereinafter, various embodiments of the disclosure may be described with reference to accompanying drawings. Accordingly, those of ordinary skill in the art will recognize that modification, equivalent, and/or alternative on the various embodiments described herein can be variously made without departing from the scope and spirit of the disclosure. With regard to description of drawings, similar components may be marked by similar reference numerals.
Referring to 1, according to a comparative example, a display device 10 may include a housing 11 and a display 12.
The housing 11 may form an outer portion of the display device 10. The display 12 may be exposed through a cover glass included in the housing 11, and may output various types of content (e.g., a drama or a movie).
According to a comparative example, the display device 10 may terminate unnecessary some of applications being executed, when a storage capacity of a memory is insufficient. When the some applications are terminated, the storage capacity of the memory may be secured. Accordingly, the display device 10 may execute another application and may improve the driving performance of the display device 10.
However, some applications may be applications (hereinafter, a first group application or an application belonging to a first group) re-executed without a trigger, even if the execution of the some application is terminated. Even if the first group application is terminated, the first group application is immediately executed. Accordingly, the display device 10 has to terminate the first group application again. When the same operation is repeated as described above, the storage capacity of the memory may not be secured, and thus the driving performance of the display device 10 may be degraded. For example, as illustrated in
According to an embodiment of the disclosure, a display device 100 may include a housing 110 and a display 120.
The housing 110 forms an outer portion of the display device 100, thereby protecting various components, which are included in the display device 100, from an external shock.
The display 120 may be provided inside the housing 110. The display 120 may output various types of content (e.g., a drama, or a movie), and may output different types of content depending on user inputs.
According to an embodiment of the disclosure, the display device 100 may store the first group application and a second group application (or an application belonging to a second group) executed by a trigger after execution-terminated. For example, a web-server demon may be included in the first group application. The web-server demon may execute an application corresponding to a request of a client or may provide a service corresponding to the request, when receiving the request of the client in a background state. The web-server demon immediately performs a specific operation in response to the request of the client. Accordingly, the web-server demon may be immediately re-executed even if the display device 100 terminates the execution of the web-server demon. According to another embodiment, a media application (YouTube™) may be included in the second group application. The media application may not exert an influence on another function of the display device 100, even if the media application is terminated. Accordingly, even if the display device 100 terminates the media application, the media application may not be re-executed as long as a specific trigger (e.g., a user input) is not applied.
According to an embodiment of the disclosure, the display device 100 may terminate the second group application without terminating the first group application, when the storage capacity of the memory is insufficient. When the second group application is terminated, the second group application is not re-executed without a specific trigger. Accordingly, the storage capacity of the memory may be secured, and the driving performance of the display device 100 may be improved. For example, as illustrated in
Referring to
The memory 130 may store various data necessary to drive the display device 100. The data may include a first group application 130a, a second group application 130b, a program, or a relevant command. The program may include, for example, an operating system (OS), or a middleware. In the disclosure, the memory 130 may be referred to as a random access memory (RAM).
The processor 140 may be electrically connected with the memory 130. The processor 140 may execute a program to control another component (e.g., the display 120) connected with the processor 140 and may process and compute various data. For example, the processor 140 may change a screen which is output through the display 120 or may control an On/Off state of the display 120. In the disclosure, the processor 140 may be referred to as a central processing unit (CPU).
According to an embodiment, the processor 140 may measure a storage capacity (or a spare storage capacity) of the memory 130. The storage capacity may indicate an amount of a spare space in which the memory 130 stores data. The processor 140 may terminate the second group application 130b without terminating the first group application 130a, when the measured storage capacity is equal to or less than a preset value. In other words, the processor 140 may secure the storage capacity of the memory 130 by terminating the second group application 130b, when the storage capacity of the memory 130 is insufficient. When the storage capacity of the memory 130 is secured, the data processing ability or the calculation performance of the processor 140 may be improved, and a phenomenon of outputting the blue screen or temporarily stopping the screen of the display 120 may not occur.
According to an embodiment, the memory 130 may store the sequence of terminating the second group application 130b. The processor 140 may terminate the second group application 130b following the termination sequence without terminating the first group application 130a, when the storage capacity of the memory 130 is equal to or less than the preset value. For example, when an application ‘a’, an application ‘b’, and an application ‘c’ are stored in the memory 130 such that the applications are terminated in order of the application ‘a’, the application ‘b’, and the application ‘c’, the processor 140 may measure the storage capacity of the memory 130 and may terminate the applications in the above order.
According to an embodiment, the processor 140 may not terminate the first group application 130a and the second group application 130b, when the storage capacity of the memory 130 exceeds the preset value. In other words, when the storage capacity of the memory 130 is sufficient, because it is unnecessary to terminate an application which is being executed, the processor 140 may not terminate the first group application 130a and the second group application 130b.
Referring to
The processor 140 may include a measuring unit 141, a low memory management (LMM) 142, a setting unit 143, and a receiving unit 144.
The measuring unit 141 may measure the storage capacity of the memory 130. When the measured storage capacity exceeds the preset value, the measuring unit 141 may continuously perform a measuring operation until the storage capacity is equal to or less than the preset value. To the contrary, when the measured storage capacity is equal to or less than the preset value, the measuring unit 141 may notify the LMM 142 of that the storage capacity of the memory 130 is insufficient.
The LMM 142 may terminate the second group application 130b without terminating the first group application 130a, when the measured storage capacity is equal to or less than the preset value. According to an embodiment, the priorities 130c of the applications included in the second group application 130b may be different each other. The LMM 142 may sequentially terminate the applications included in the second group application 130b, based on the priorities 130c. In the disclosure, the LMM 142 may be referred to as a memory managing unit.
The setting unit 143 may set the priority 130c. For example, the setting unit 143 may set a higher priority 130c to the second group application 130b and may set a lower priority 130c to the first group application 130a. When the storage capacity of the memory 130 is equal to or less than the preset value, the LMM 142 may terminate the second group application 130b having the higher priority 130c, or vice versa.
According to an embodiment, the setting unit 143 may be included in the LMM 142. In other words, the LMM 142 may set the priorities 130c of the first group application 130a and the second group application 130b. When the storage capacity of the memory 130 is equal to or less than the preset value, the LMM 142 may terminate the second group application 130b having the higher priority 130c.
The receiving unit 144 may receive a user input. For example, when a user intends to execute the media application through a remote controller after the LMM 142 terminates the media application, the receiving unit 144 may receive the user input. The LMM 142 may execute the media application based on the user input, and may output a media execution screen through the display 120.
In the specification, components having the same reference numerals as those of the display device 100 illustrated in

In operation 420, the processor 140 may determine whether the storage capacity measured in operation 410 is equal to or less than a preset value. When the measured storage capacity exceeds the preset value, the processor 140 may repeatedly perform operation 410. To the contrary, when the measured storage capacity is equal to or less than the preset value, the processor 140 may perform operation 430. For example, when the preset value is 0.5 GB, and the storage capacity is 0.3 GB, the processor 140 may perform operation 430.
In operation 430, the processor 140 may terminate the second group application 130b without terminating the first group application 130a. In other words, the processor 140 may terminate the second group application 130b without terminating the first group application 130a, when the storage capacity of the memory 130 is insufficient. When the second group application 130b is terminated, the second group application is not re-executed without a specific trigger. Accordingly, the storage capacity of the memory 130 may be ensured, and data processing or computing performance of the processor 140 may be improved. Accordingly, a phenomenon of outputting the blue screen or temporarily stopping the screen of the display 120 may not occur.
Referring to
In operation 520, the processor 140 may set mutually different priorities 130c to the first group application 130a and the second group application 130b. The processor 140 may set a lower priority 130c to the first group application 130b and may set a higher priority 130c to the second group application 130a, or vice versa.
In operation 530, the processor 140 may measure the storage capacity of the memory 130. For example, when the total storage capacity of the memory 130 is 4 GB, and an amount of the stored data is 3 GB, the storage capacity may be 1 GB.
In operation 540, the processor 140 may determine whether the storage capacity measured in operation 530 is equal to or less than the preset value. When the measured storage capacity exceeds the preset value, the processor 140 may repeatedly perform operation 530. To the contrary, when the measured storage capacity is equal to or less than the preset value, the processor 140 may perform operation 550.
In operation 550, the processor 140 may select at least one of applications being executed. For example, in the state that the application ‘a’, the application ‘b’, and the application ‘c’ are being executed, the processor 140 may select the application ‘a’.
In operation 560, the processor 140 may determine whether the application selected in operation 550 is included in the first group application 130a. When the application selected in operation 550 is included in the first group application 130a, operation 570 may be performed. When the application selected in operation 550 is not included in the first group application 130a, operation 580 may be performed. When the application selected in operation 550 is included in the first group application 130a, the processor 140 may select another application without terminating the application selected in operation 550. To the contrary, when the application selected in operation 550 is not included in the first group application 130a (is included in the second group application 130b), the processor 140 may terminate the application selected in operation 550.
According to an embodiment, in operation 560, the processor 140 may measure the priority 130c of the application selected in operation 550. The processor 140 may determine whether the application selected in operation 550 is included in the first group application 130a, based on the priority 130c.
In operation 570, the processor 140 may select another application instead of the application selected in operation 550. According to an embodiment, the processor 140 may select the application ‘b’ among the application ‘a’, the application ‘b’, and the application ‘c’. When the application ‘b’ is included in the first group application 130a, the processor 140 may repeatedly perform operation 570. When the application ‘b’ is not included in the first group application 130a, the processor 140 may terminate the application ‘b’.
In operation 580, the processor 140 may terminate the application selected in operation 550. In other words, when the application selected in operation 550 is included in the second group application 130b, the processor 140 may terminate the execution of the selected application.

According to an embodiment, the setting unit 143 having the classification result received therein may set mutually different priorities 130c to the first group application 130a and the second group application 130b. For example, the setting unit 143 may set a lower priority 130c to the first group application 130b and may set a higher priority 130c to the second group application 130b, or vice versa.
The LMM 142 may measure the storage capacity of the memory 130. The LMM 142 may measure the priority 130c of the application being executed, when the measured storage capacity is equal to or less than the preset value.
