All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The terms "first," "second," and "third," etc. in the description and claims of the present invention and the above-described drawings are used for distinguishing between different objects and not for describing a particular order. Furthermore, the terms "comprises" and any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or modules is not limited to the listed steps or modules but may alternatively include other steps or modules not listed or inherent to such process, method, article, or apparatus.
Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the invention. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.
It should be understood that the technical solution of the embodiment of the present invention may be specifically applied to a Mobile Terminal (Terminal) configured with an OLED display screen, such as a Mobile phone (e.g., an Android Mobile phone, an iOS Mobile phone, etc.), a television, a tablet computer, a Mobile Internet Device (MID), a Personal Digital Assistant (PDA), etc. An OLED display is a display formed of organic light-emitting materials that emit colored light when energized. In order to flexibly display more images and text information, a display screen is generally manufactured to have a lattice structure, that is, the whole screen is composed of a plurality of light emitting elements arranged in order, and an electric array image having gray scale is formed by controlling the brightness of each light emitting element, wherein the light emitting elements are composed of organic light emitting materials. The mobile terminal may also be referred to as User Equipment (User Equipment, abbreviated as "UE"), a terminal, a wireless terminal or a mobile station (mobile station, abbreviated as "MS"), and the like.
The embodiment of the invention discloses a light-emitting control method and device of a light-emitting element and a mobile terminal, which can control the light-emitting of the light-emitting element through a preset duty ratio so as to slow down the aging of the light-emitting element. The details are described below.
Referring to fig. 1, fig. 1 is a schematic flow chart illustrating a light emitting control method of a light emitting device according to an embodiment of the present invention. Specifically, as shown in fig. 1, the method for controlling light emission of a light emitting element according to an embodiment of the present invention may include:
101. when the current light-emitting element needs to emit light, whether the current light-emitting element is in a preset target area range is judged.
It should be understood that the method of the embodiment of the present invention may be specifically applied to the above-mentioned mobile terminal (simply referred to as "terminal"), and the display screen of the terminal is composed of at least one light-emitting element. Further, the light emitting element corresponds to a screen pixel, and may be specifically an OLED. Each screen pixel includes red sub pixel point (R), green sub pixel point (G) and blue sub pixel point (B), then each sub pixel point in this screen pixel can be an OLED, and the OLED that this red sub pixel point (R) corresponds is used for showing red (red light), the OLED that green sub pixel point (G) corresponds is used for showing green (green light), and the OLED that blue sub pixel point (B) corresponds is used for showing blue (blue light), thereby carries out the colour mixture through RGB and shows.
In a specific embodiment, some specific areas, i.e. target areas, may be configured in advance in the display screen, such as areas where display contents of a status bar or a virtual key display bar of the display screen may not change or change little for a long time, resulting in easy aging. So that the aging of the light emitting elements of the target area can be slowed down by controlling the light emission of the light emitting elements included in the portion of the target area.
102. And if the current light-emitting element is within the range of the target area, controlling the current light-emitting element to alternately emit light and not emit light according to a preset duty ratio.
The duty ratio may refer to a ratio of a time duration corresponding to the non-light emission to a total time duration corresponding to the light emission and the non-light emission.
In a specific embodiment, when it is determined that light emission needs to be performed by the light emitting element, that is, the OLED needs to be lit, it is determined whether a display area where the OLED needs to be lit is a target area in the display screen by detecting, and when the display area is the target area, it is determined that light emission (display) control is performed on the OLED. Specifically, the light emission and non-light emission of the OLED may be controlled according to a predetermined duty ratio, where the duty ratio determined by the first time period corresponding to the light emission and the second time period corresponding to the non-light emission (light emission stop) may be preset. For example, assuming that the period is 1 second, in the period of 1 second, 0.8 second of the light emitting elements emits light, and the remaining 0.2 second of the light emitting elements does not emit light. Because the non-luminous time of the light-emitting element is short, the user sees that the display content is always displayed due to the residual visual effect, the display effect is not influenced, and the aging of the OLED is effectively delayed by switching control of light emission and non-light emission.
In the embodiment of the invention, when it is determined that the current light-emitting element needs to emit light, the loss of the light-emitting element can be reduced by judging whether the current light-emitting element is in the preset target area range and controlling the current light-emitting element to alternately emit light and not emit light according to the preset duty ratio in the target area range, that is, by controlling the alternate display and non-display of a specific display area in the display screen, so that the aging of the light-emitting element is slowed down.
Further, referring to fig. 2, fig. 2 is a schematic flow chart of another light-emitting control method of a light-emitting device according to an embodiment of the present invention. Specifically, as shown in fig. 2, the method for controlling light emission of a light emitting element according to an embodiment of the present invention may include:
201. when the current light-emitting element needs to emit light, the identification information of the display area where the current light-emitting element is located is acquired.
Specifically, the identification information may include a region name (e.g., a status bar), a region location coordinate, and the like associated with the current light emitting element, which is not limited in the embodiments of the present invention.
202. And detecting whether the identification information of the display area is matched with the identification information of a preset target area.
Optionally, the target area may include an area of the display screen where the display content may not change or change little for a long time, such as a status bar, a virtual key display bar, and the like.
Specifically, the mobile terminal stores identification information of the target area, such as a name of the target area, a position coordinate of the target area, and the like. It is to be understood that the acquired identification information of the display region where the current light-emitting element is located corresponds to the stored identification information of the target region, as is region name information, or as is region position coordinate information.
Further, when it is detected that the identification information of the display area where the current light emitting element is located matches the identification information of the target area, step 203 may be executed, that is, it may be determined that the current light emitting element is within the range of the target area; otherwise, it can be determined that the current light-emitting element is not within the target area, and the light-emitting element can still be controlled to emit light in the existing manner.
203. Determining that the current light-emitting element is within the target area.
204. And in each preset light-emitting period, controlling the current light-emitting element to emit light in a first time length, and controlling the current light-emitting element to stop emitting light in a second time length.
The first duration corresponding to the light emission is longer than the second duration corresponding to the no light emission (light emission stopping), the sum of the first duration and the second duration is equal to the preset light emission period, and the duration proportion of the first duration and the second duration (namely the duty ratio determined by the first duration and the second duration) can be obtained through pre-configuration. In order to satisfy the visual residual effect, a ratio of the second time period to the first time period may be set to not more than 1: 4. For example, assuming that the preset light emitting period is 1 second, within a period of 1 second, 0.8 second of the light emitting elements emits light, the remaining 0.2 second of the light emitting elements does not emit light, and the light emitting elements are controlled to repeat the light emission and the non-light emission with the light emitting period. The non-luminous time of the light-emitting element is short, so that the effect of visual residual is achieved, a user sees that the display content is displayed all the time, the display effect cannot be influenced, and the aging of the OLED is effectively delayed through the switching control of the light-emitting and the non-light-emitting.
In the embodiment of the invention, when the current light-emitting element is determined to emit light, whether the light-emitting element is in the target area range can be determined by detecting whether the identification information of the display area where the current light-emitting element is located is matched with the identification information of the preset target area, so that when the light-emitting element is determined to be in the target area range, the current light-emitting element is controlled to alternately emit light and not emit light according to the preset duty ratio, namely, the loss of the light-emitting element can be reduced by controlling the alternate display and the non-display of the specific display area in the display screen, and the aging of the light-emitting element is slowed down.
Referring to fig. 3, fig. 3 is a schematic structural diagram of a light-emitting control device according to an embodiment of the present invention. Specifically, the apparatus according to the embodiment of the present invention may be disposed in the mobile terminal, and a display screen of the mobile terminal is composed of at least One Light Emitting Device (OLED). As shown in fig. 3, the light emitting control apparatus according to the embodiment of the present invention may include a determination module 11 and a light emitting control module 12. Wherein,
the judging module 11 is configured to judge whether the current light emitting element is within a preset target area range when light emission through the current light emitting element is required.
In a specific embodiment, the mobile terminal is configured with a target area, where the target area is some specific areas in the display screen, such as a status bar or a virtual key display bar of the display screen, where display contents may be unchanged or slightly changed for a long time, which may lead to aging. Therefore, when light emission is required to be performed through one or more light emitting elements, the determining module 11 may determine whether the part of the light emitting elements is within the target area range, so as to trigger and control the light emission of the part of the light emitting elements to slow down the aging of the light emitting elements in the target area.
The light emitting control module 12 is configured to control the current light emitting element to alternately emit light and not emit light according to a preset duty ratio when the determination result of the determining module 11 is that the current light emitting element is within the target area range.
The duty ratio may refer to a ratio of a time duration corresponding to the non-light emission to a total time duration corresponding to the light emission and the non-light emission.
In a specific embodiment, when it is determined that light emission needs to be performed by the light emitting element, that is, the OLED needs to be lit, the determining module 11 may detect whether the display area where the OLED needs to be lit is a target area in the display screen, and when the display area is the target area, it is determined to trigger light emission (display) control of the OLED. Therefore, the light emission control module 12 can control the light emission and non-light emission of the OLED according to a predetermined duty ratio, wherein the duty ratio determined by the first time period corresponding to the light emission and the second time period corresponding to the non-light emission (light emission stop) can be preset. For example, assuming that the period is 1 second, the light emission control module 12 may control the light emitting elements to emit light for 0.8 second and the remaining light emitting elements to emit no light for 0.2 second within the period of 1 second. Because the non-luminous time of the light-emitting element is short, the user sees that the display content is always displayed due to the residual visual effect, the display effect is not influenced, and the aging of the OLED is effectively delayed by switching control of light emission and non-light emission.
In the embodiment of the invention, when it is determined that the current light-emitting element needs to emit light, the loss of the light-emitting element can be reduced by judging whether the current light-emitting element is in the preset target area range and controlling the current light-emitting element to alternately emit light and not emit light according to the preset duty ratio in the target area range, that is, by controlling the alternate display and non-display of a specific display area in the display screen, so that the aging of the light-emitting element is slowed down.
Further, referring to fig. 4, fig. 4 is a schematic structural diagram of another light-emitting control device according to an embodiment of the present invention. Specifically, the apparatus according to the embodiment of the present invention may include the determination module 11 and the light-emitting control module 12 of the light-emitting control apparatus according to the embodiment of the present invention shown in fig. 3. Further, in the embodiment of the present invention, the determining module 11 may specifically include:
an identification acquisition unit 111 configured to acquire identification information of a display area where the current light-emitting element is located;
a matching unit 112, configured to detect whether the identification information of the display area where the current light-emitting element is located, acquired by the identification acquisition unit 111, matches with identification information of a preset target area;
a determining unit 113, configured to determine that the current light-emitting element is within the target area range when the matching result of the matching unit 112 is that the identification information of the display area matches the identification information of the target area.
Specifically, the identification information may include a region name (e.g., a status bar), a region location coordinate, and the like associated with the current light emitting element, which is not limited in the embodiments of the present invention.
Further, the mobile terminal stores therein identification information of the target area, such as a name of the target area, position coordinates of the target area, and the like. It is to be understood that the acquired identification information of the display region where the current light-emitting element is located corresponds to the stored identification information of the target region, as is region name information, or as is region position coordinate information.
Further, in the embodiment of the present invention, the light emitting control module 12 may be specifically configured to:
and in each preset light-emitting period, controlling the current light-emitting element to emit light in a first time length, and controlling the current light-emitting element to stop emitting light in a second time length.
The first duration corresponding to the light emission is longer than the second duration corresponding to the no light emission (light emission stopping), the sum of the first duration and the second duration is equal to the preset light emission period, and the duration proportion of the first duration and the second duration (namely the duty ratio determined by the first duration and the second duration) can be obtained through pre-configuration. To ensure that the visual retention effect is satisfied, the ratio of the second duration to the first duration may be set to not more than 1: 4. The light emission control module 12 can thus alternately control the light emission and non-light emission of the light emitting element according to a preset light emission period (e.g., 1 second) and the first and second time periods.
In the embodiment of the invention, when the current light-emitting element is determined to emit light, whether the light-emitting element is in the target area range can be determined by detecting whether the identification information of the display area where the current light-emitting element is located is matched with the identification information of the preset target area, so that when the light-emitting element is determined to be in the target area range, the current light-emitting element is controlled to alternately emit light and not emit light according to the preset duty ratio, namely, the loss of the light-emitting element can be reduced by controlling the alternate display and the non-display of the specific display area in the display screen, and the aging of the light-emitting element is slowed down.
