Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as detailed in the appended claims.
In the related art, in a single DDIC (display driver integrated circuit, which may be referred to as a driver chip for short) AMOLED screen, the power consumption ratio of the DDIC to the screen is about 20:1, so that the DDIC is a main power consumption device in the screen-off display AOD mode. Therefore, the technology of using double DDICs or even more DDICs to drive the display screen simultaneously improves the power consumption of the display screen while increasing the number of the DDICs. Aiming at the problem of overhigh power consumption of the display screen, a new display mode is provided, and only part of driving chips in the multi-driving display screen are used for providing normal display functions for the display screen.
Fig. 1 is a flowchart illustrating a driving method of a display screen according to an exemplary embodiment. The driving method of the display screen can be used in a terminal, as shown in fig. 1, and includes the following operation steps.
In step S11, determining a display mode of the multi-drive display panel;
in step S12, when the display mode of the multi-driver display is the preset display mode, the state of one or more driver chips of the multi-driver display is controlled to be a normal operating state. The number of the driving chips in the normal working state is less than the total number of the driving chips of the multi-drive display screen, and the preset display mode comprises the step of lightening part of pixel points on the screen.
Therefore, the technical scheme of the embodiment provides a new display mode for the multi-drive display screen, that is, part of the drive chips in the multi-drive display screen are controlled to work normally, so that part of the pixel points on the screen can be lightened for displaying the screen content. This way, the way of lighting a part of the pixel points on the screen means that the pixel points on the screen are in the off state, that is, by reducing the number of the lighted pixel points, the power consumption of the multi-drive display screen is reduced. Accordingly, the power consumption of the device corresponding to the multi-drive display screen, such as a mobile phone or other personal equipment, is also reduced.
In the above step S12, the normal operation state related to the driver chip includes a state of normal operation after power-on. The driving chip in the normal working state can at least normally control the on and off of all pixel points in the corresponding position range in the screen. In this embodiment, taking the driving chip DDIC as an example, the normal operating state of the driving chip may include a normal (normal) state of the driving chip, and the power-off (power-off) state, a sleep (sleep) state, and a standby (standby) state of the driving chip are all considered as abnormal operating states.
In addition, in this embodiment, all the driver chips of the multi-driver display support a function of receiving different instructions, that is, an on instruction may be sent to one or more driver chips of the multi-driver display to control the states of the driver chips to be normal operating states, and an off instruction may be sent to other driver chips of the multi-driver display to control the states of the driver chips to be other states than the normal operating states.
The present embodiment further provides another driving method for a display screen, where the method controls the state of one or more driving chips of a multi-driving display screen to be a normal operating state by using the following method:
one or more driving chips are selected from all driving chips of the multi-drive display screen according to a first rule, and the states of the selected driving chips are controlled to be normal working states.
In the above method, the first rule may include a plurality of selection manners, which is not particularly limited in this embodiment. For example, a set number of driving chips may be randomly selected, where the set number is less than the total number of driving chips of the multi-driving display panel. For another example, a set driver chip may be selected, and the set driver chip may be configured in advance, or may be set in real time according to a user operation instruction.
It can be seen from the above that, in the technical scheme of this embodiment, when the driver chip in the normal working state is selected, the driver chip can be randomly selected, also can be selected according to the default configuration, and also can be selected in real time according to the user requirements. And all the driving chips of the multi-drive display screen respectively control the on and off of the pixel points in different position ranges in the screen for displaying the screen content, so that after the driving chip in the normal working state is selected, the screen content can be displayed in the position range in the screen corresponding to the driving chip in the normal working state. That is, after the driver chip in the normal operating state is selected, the display range of the screen content is determined. Therefore, the mode of selecting the driving chip in the working state in the technical scheme of the embodiment is various, so that the display range of the screen content can be selected in various ways. Namely, on the basis of reducing the power consumption of the multi-drive display screen, the user experience is enriched.
The present embodiment further provides another driving method for a display screen, where the method controls the state of one or more driving chips of a multi-driving display screen to be a normal operating state by using the following method:
according to a second rule, selecting two or more than two driving chips from all driving chips of the multi-drive display screen, and configuring the selected driving chips into working driving chips in turn;
and controlling the state of the working driving chip to be a normal working state.
In this embodiment, since the implementation of this embodiment is a manner in which the driver chips normally operate in turn, the second rule in this embodiment may include various selection manners, various turn manners, and combinations of various selection manners and turn manners.
For example, the selection mode included in the second rule may include random selection, selection according to a preset configuration, real-time selection according to a user instruction, and the like. The number of the selected driving chips is at least two, and can be at most the same as the total number of the driving chips of the multi-drive display screen. The implementation of different selection manners can be seen in the various selection manners mentioned in the first rule above.
The alternate mode included in the second rule may be to sequentially configure corresponding driver chips from the selected driver chips as working driver chips according to a set arrangement order. Wherein, the working driving chip configured each time is not identical to the working driving chip configured last time. For example, the driver chips configured for operation for the first time are the driver chip 1 and the driver chip 2, and the driver chips configured for operation for the second time may be the driver chip 2, or the driver chip 2 and the driver chip 3. The time length for the working driving chip configured each time to maintain the normal working state can be a fixed time length, a random time length, a variable time length showing a preset rule, or a time length set by a user in real time.
The selected driver chips may also be divided into two or more driver chip groups. The driver chip sets can be sequentially configured into working driver chip sets according to a set sequence, and all the driver chips in the working driver chip sets are working driver chips. The number of the driver chips included in each driver chip group may be the same or different. The number of the driving chips in each driving chip group is less than the total number of the driving chips of the multi-drive display screen.
In this embodiment, the second rule may be configured in advance, or may be configured according to a user instruction.
It can be seen from the above that, for the similar reason as the embodiment of selecting the driving chip in the normal operating state according to the first rule, the technical solution of this embodiment controls different driving chips to be the driving chips in the normal operating state in turn, and enriches the user experience on the basis of reducing the power consumption of the multi-drive display screen. In addition, as can be known from the foregoing description, all the driver chips of the multi-driver display screen respectively control the on/off of the pixel points in different position ranges in the screen for displaying the screen content, so that when different driver chips are selected to be in a normal operating state, the display range of the screen content will change along with the change of the driver chips in the normal operating state. That is, the screen content can not be fixedly displayed in the same position range, so that the screen burning phenomenon can be greatly reduced on the basis of reducing the power consumption of the multi-drive display screen.
The embodiment also provides another driving method of the display screen, which determines the display mode of the multi-drive display screen in the following mode.
When any trigger condition of a preset display mode is met, determining the display mode of the multi-drive display screen to be the preset display mode;
the trigger condition of the preset display mode at least comprises any one or more of the following conditions:
the state of the device corresponding to the multi-drive display screen is a set state;
receiving an operation instruction for reducing the power consumption of the display screen by a device corresponding to the multi-drive display screen;
the operating system time of the device corresponding to the multi-drive display screen belongs to a set time period;
the folding angle of the multi-drive display screen is equal to or larger than a set angle.
In the method, the trigger conditions of the preset display mode may be pre-configured, or may be configured autonomously by the user, or one or more of the trigger conditions may be determined by the pre-configuration, and the rest may be determined by the autonomous configuration by the user. The present embodiment does not limit this.
When the state of the device corresponding to the multi-drive display screen is a set state, corresponding operation can be performed according to a preset display mode when the device enters the set state. In this embodiment, the setting state may include various states having low requirements for the display function. The required display function is determined according to the state of the device, so that the preset display mode is selected, and the number of the driving chips in the normal working state is reduced on the basis of the actual use condition of the device corresponding to the multi-drive display screen, so that the power consumption of the device corresponding to the multi-drive display screen is reduced, and the performance of the device is improved.
The triggering condition comprises that when the device corresponding to the multi-drive display screen receives an operation instruction for reducing the power consumption of the display screen, the device can perform corresponding operation according to a preset display mode when receiving the operation instruction in real time. In this embodiment, the operation instruction for reducing the power consumption of the display screen may include all operation instructions related to the display configuration parameters, for example, an operation instruction of a half-screen display (for example, an up-screen display, a down-screen display, a left-screen display, and the like) initiated by a user. The scheme for triggering the preset display mode reduces the number of the driving chips in the normal working state on the basis of the actual requirements of users, thereby reducing the power consumption of the device corresponding to the multi-drive display screen and improving the performance of the device.
The triggering condition comprises that when the operating system time of the device corresponding to the multi-drive display screen belongs to a set time period, corresponding operation can be performed according to a preset display mode at the set time. For example, the set time period may include a time period during which the user has a rest at night, or may include a work time period set by the user. The required display function is determined according to the using time period of the device corresponding to the multi-drive display screen, so that the preset display mode is selected, and the actual scene of the device used by a user is considered, so that the power consumption of the device corresponding to the multi-drive display screen is reduced, and the user experience is improved.
The triggering condition comprises that when the folding angle of the multi-drive display screen is equal to or larger than a set angle, the state of a device corresponding to the multi-drive display screen can be determined according to the folding state when the flexible display screen is folded or overturned, and then whether the corresponding operation is carried out according to a preset display mode is determined according to the state of the device. For example, when the folding angle of the multi-driver display is equal to or greater than the set angle, the state of the device corresponding to the multi-driver display may be considered as a state with a low requirement for the display function, such as standby or screen locking, and at this time, it may be determined to perform the corresponding operation according to the preset display mode. Therefore, the power consumption of the device corresponding to the multi-drive display screen is reduced, and the performance of the device is improved.
The present embodiment further provides another driving method for a display screen, in which the setting state at least includes any one or more of the following:
an Always On Display (AOD) display mode, a standby mode, an emergency mode, an airplane mode, and a charging mode.
Therefore, according to the requirements, corresponding operation can be selected according to a preset display mode, power consumption of the multi-drive display screen is reduced, and accordingly power consumption of the device corresponding to the multi-drive display screen is reduced.
The present embodiment further provides another driving method of a display screen, which, as shown in fig. 2, includes the following operations:
in step S21, the display mode of the multi-drive display screen is updated;
in step S22, when the updated display mode of the multi-driver display is a display mode other than the preset display mode, the states of all the driver chips of the multi-driver display are controlled to be normal operating states.
The determining that the display mode of the multi-drive display screen is the display mode other than the preset display mode may be determining that the display mode is the display mode other than the preset display mode when it is determined that all trigger conditions of the preset display mode are not met. Or when the trigger condition of normal display is found to be satisfied, the display mode other than the preset display mode can be determined. Herein, the display modes other than the predetermined display mode (e.g. normal display mode) are required for normal use, and the predetermined display mode is required for low power consumption, which is a special requirement other than normal use. Therefore, the priority of the preset display mode is lower than that of the display modes other than the preset display mode, and the priority of the display modes other than the preset display mode is higher. In this way, when the trigger condition of the preset display mode and the trigger condition of the normal display are simultaneously met, the display mode with high priority is selected to perform the corresponding operation, namely the normal display mode is used to perform the corresponding operation.
It can be seen from the above that, according to the actual use situation, in consideration of the fact that the display function requirement changes, when the display function requirement returns to normal, all the driving chips of the multi-drive display screen are controlled to normally work to achieve the effect of normal display. Therefore, the display mode of the multi-drive display screen can be switched between the preset display mode and the normal display mode, and the normal use of the device is not influenced on the basis of reducing the power consumption of the device corresponding to the multi-drive display screen.
Fig. 3 is a flowchart illustrating a driving method of a display screen according to an exemplary embodiment, which may be used at a mobile terminal. In this embodiment, it is assumed that the multi-driver display panel includes two DDICs, as shown in fig. 4, the two DDICs can independently power up and down, the left DDIC is master MIPI (Mobile Industry Processor Interface), PORT 0 is used, and the right DDIC is slave MIPI, PORT1 is used. As shown in fig. 3, the method includes the following operations.
In step 31, it is detected that the mobile terminal corresponding to the multi-drive display screen is in the AOD mode.
In step 32, the display mode of the multi-drive display screen is determined to be the preset display mode.
As described above, the triggering condition of the preset display mode may include that the state of the device corresponding to the multi-driver display is a set state, where the set state includes the AOD mode, and thus the display mode of the multi-driver display is determined to be the preset display mode.
In step 33, only one DDIC is turned on for AOD display, and the other DDIC is powered down to enter a sleep state.
In this embodiment, turning on one DDIC means controlling the state of the DDIC to be a normal operating state, normal state. Specifically, different instructions may be sent to the left DDIC and the right DDIC respectively in a programming manner to control the state of one DDIC to be a normal state and control the other DDIC to be powered down to enter a sleep state. In addition, for two DDICs sharing a power supply, the state of one DDIC may be controlled to be normal, and the other DDIC may be controlled to enter sleep state or stand by state.
In other alternative embodiments, the operation of step 33 may also include the following operations:
and turning on the left DDIC and the right DDIC in turn to perform AOD display.
That is, the on command may be sent to the left DDIC and the right DDIC alternately in a programmed manner. In this way, after each time of sending the open instruction, the state of the DDIC receiving the open instruction is controlled to be normal state, and another DDIC not receiving the open instruction enters sleep state.

Therefore, the technical solution of the present embodiment provides a new driving apparatus, that is, a part of driving chips in a multi-driving display screen are controlled to operate normally, so that a part of pixel points on the screen can be lighted for displaying screen content. By the method, the power consumption of the multi-drive display screen is reduced without lighting all pixel points on the screen. Accordingly, the power consumption of the device corresponding to the multi-drive display screen, such as a mobile phone or other personal equipment, is also reduced.
The present embodiment further provides another driving apparatus for a display screen, wherein the second module 52 can control the state of one or more driving chips of the multi-driving display screen to be a normal operating state according to the following manner:
one or more driving chips are selected from all driving chips of the multi-drive display screen according to a first rule, and the states of the selected driving chips are controlled to be normal working states.
