Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
Example one
Fig. 1 shows a flowchart of steps of a time display method according to a first embodiment of the present invention, where the method may be applied to a display driver chip of a time display device, where the time display device further includes an application processor, and referring to fig. 1, the method may specifically include the following steps:
step 101: and receiving target time image information sent by the application processor.
In the embodiment of the present invention, the mobile terminal may include at least one mode capable of displaying time without performing a screen-up operation, for example, a power saving mode, and the user may start such a mode by clicking a virtual button for starting the mode, or long pressing an off key.
When a certain mode is turned on, the application processor may determine target time image information corresponding to the current time, where the current time may be used as a starting time, where the target time image information may include image information corresponding to the current time displayed in a preset pattern, for example, an hour hand position, a minute hand position, a second hand position, and the like corresponding to the current time displayed in a dial clock pattern, and this is not specifically limited in the embodiment of the present invention. And the application processor can send the target time image information corresponding to the current time to the display driving chip, so that the display driving chip receives the target time image information.
Then, the application processor can enter a sleep state without sending time-related information to the display driver chip, and the application processor can be awakened until the mobile terminal exits the power saving mode or other information needing to be updated is sent.
Step 102: and determining image updating information corresponding to the preset time length from the starting time.
After receiving the target time image information sent by the application processor, the display driver chip may determine image update information corresponding to a preset time period from the start time, where the image update information is a variation that should be generated when the time image corresponding to the start time passes the preset time period, for example, a pointer angle variation corresponding to a dial clock, or a digital variation corresponding to an electronic clock.
Step 103: and generating a time image corresponding to the preset time duration from the initial time according to the target time image information and the image updating information.
In this step, the display driver chip may generate a time image corresponding to a preset duration from the start time according to the target time image information corresponding to the start time and a variation that should be generated when the time image corresponding to the start time passes the preset duration.
Step 104: and outputting the time image for display when the preset time length is passed after the time is counted from the starting time.
In the embodiment of the present invention, when receiving the target time image information sent by the application processor, the display driver chip may start timing from the start time, and when the preset time length elapses from the start time, the display driver chip may output the time image corresponding to the lapse of the preset time length from the start time to the display panel, and the display panel may display the time image.
Step 105: and taking the time obtained by adding the starting time and the preset time length as the starting time, taking the time image information corresponding to the time image as the target time image information, and returning to the step of determining the image updating information corresponding to the time when the preset time length passes from the starting time.
After the display driver chip outputs the time image, the display driver chip may use a time obtained by adding the start time and the preset time length as a new start time, use time image information corresponding to the time image as new target time image information, and then may return to the step of determining image update information corresponding to the time when the preset time length elapses from the start time. Therefore, the application processor only needs to send target time image information to the display driving chip once at the starting time, and the subsequent display driving chip can perform self-updating of the time image in a circulating mode, so that the application processor does not need to be kept in a working state all the time, and the power consumption of the mobile terminal is reduced.

Example two
Fig. 2 is a flowchart illustrating steps of a time display method according to a second embodiment of the present invention, where the method may be applied to a display driver chip of a time display device, and the time display device further includes an application processor, and referring to fig. 2, the method may specifically include the following steps:
step 201: and the display driving chip receives the target time image information sent by the application processor.
In this embodiment of the present invention, when a user triggers a mode capable of displaying time without performing a screen-up operation in a mobile terminal, the application processor may first send a control command to the display driver chip to instruct the display driver chip to enter a corresponding display mode, and then the application processor may send target time image information to the display driver chip, and then the display driver chip may store the target time image information in a specific Memory for subsequent retrieval, for example, may store the target time image information in a Font Memory, which is not specifically limited in this embodiment of the present invention. Optionally, in a specific application, the control command and the target time image information may be transmitted in a form of an MIPI (Mobile Industry Processor Interface) signal, and a transmission process follows an MIPI protocol.
In an alternative implementation, in a case where the user presets in advance that the time is displayed in the dial clock style, the target time image information may include at least one of a start time corresponding to a first minute position in the dial clock, and a start time corresponding to a first second minute position in the dial clock. Further, in a case where the user presets at least one of an hour hand pattern, a minute hand pattern, and a second hand pattern of the dial clock in advance, the target time image information may further include at least one of an hour hand pattern, a minute hand pattern, and a second hand pattern corresponding to the dial clock. The pointer pattern may specifically include at least one of pattern parameters such as a pointer color, a pointer shape, and a pointer pattern, which is not specifically limited in this embodiment of the present invention.
In another alternative implementation, in a case where the user presets in advance that the time is displayed in the electronic clock style, the target time image information may include at least one of a first hour value at which the start time corresponds to the electronic clock, a first minute value at which the start time corresponds to the electronic clock, and a first second value at which the start time corresponds to the electronic clock. Further, in a case where the user presets at least one of an hour digit pattern, a minute digit pattern, and a second digit pattern of the electronic clock in advance, the target time image information may further include at least one of an hour digit pattern, a minute digit pattern, and a second digit pattern corresponding to the electronic clock. The digital style may specifically include at least one of style parameters such as a digital color, a digital font, a digital size, and the like, which is not specifically limited in this embodiment of the present invention.
After the application processor sends the target time image information to the display driving chip, the application processor can enter a sleep state without sending time-related information to the display driving chip, and the application processor can be awakened until the mobile terminal exits a mode of displaying time without performing a bright screen operation or other information needing to be updated needs to be sent.
Step 202: and the display driving chip determines corresponding image updating information when a preset time length passes from the starting time.
In the embodiment of the present invention, in the case where the time needs to be displayed in the dial clock style, the step may specifically include at least one of the following sub-steps:
determining an hour hand rotation angle corresponding to a preset duration from the starting moment to obtain image updating information corresponding to the hour hand;
determining a minute hand rotation angle corresponding to a preset duration from the starting moment to obtain image updating information corresponding to the minute hand;
and determining a second hand rotation angle corresponding to the preset time duration from the starting time to obtain image updating information corresponding to the second hand.
Because there are intervals between the scales of the dial clock and there is a certain time difference between the time when the display driver chip receives the target time image information and the time when the display driver chip finally displays the time image, the display driver chip needs to determine how much variation should be made in the pointer position from the start time to the time when the time image is finally displayed, so as to finally display the accurate time image. In practical applications, the preset time period may be 0.5 second, 1 second, 3 seconds, and the like, which is not specifically limited in the embodiment of the present invention.
In the case where the time needs to be displayed in an electronic clock format, the step may specifically include at least one of the following sub-steps:
determining the corresponding hour value variation when a preset time length passes from the starting time to obtain image updating information corresponding to the hour;
determining the corresponding minute value variable quantity when a preset time length passes from the starting time, and obtaining image updating information corresponding to minutes;
and determining the second value variable quantity corresponding to the preset time duration from the starting time to obtain the image updating information corresponding to the second.
Step 203: and the display driving chip generates a time image corresponding to the preset time length from the initial time according to the target time image information and the image updating information.
In the embodiment of the present invention, when time needs to be displayed in a dial clock style, the step may be specifically implemented in the following manner, including: determining a second hour hand position corresponding to the first hour hand position after rotating the hour hand rotating angle; determining a corresponding second minute hand position after the first minute hand position rotates by the minute hand rotating angle; determining a second hand position corresponding to the first second hand position after the second hand rotating angle is rotated; a time image is generated with the hour hand in a second hour hand position, the minute hand in a second minute hand position, and the second hand in a second hand position. That is, the display driver chip may determine a second pointer position corresponding to the first pointer position corresponding to the start time after the preset duration, and then the display driver chip may generate a time image in which the pointer is located at the second pointer position, that is, the time image corresponding to the preset duration from the start time.
In the case that the time needs to be displayed in an electronic clock style, the step may be specifically implemented in a manner including: determining a second hour value corresponding to the first hour value after the first hour value is added with the hour value variation; determining a second minute value corresponding to the first minute value and the minute value variation after the first minute value and the minute value variation are added; determining a second value corresponding to the sum of the first second value and the second value variable quantity; and generating a time image corresponding to the second hour value, the second minute value and the second value. That is, the display driver chip may determine a second time value corresponding to the first time value corresponding to the start time after the preset duration, and then the display driver chip may generate a time image corresponding to the second time value, that is, a time image corresponding to the preset duration from the start time.
Step 204: and the display driving chip synthesizes the time image and a pre-stored first background image to obtain a synthesized image.
In the embodiment of the invention, the mobile terminal can display time on a specific background, and correspondingly, the application processor can transmit a first background image required by the display time to the display driving chip in advance. Illustratively, fig. 3 shows a first background image, which refers to an area a in fig. 3, the first background image may include a dial clock background, refer to an area B in fig. 3, the first background image may include date information, such as a calendar date of 5-21-month, a Tuesday, a lunar calendar date of seventeen-four-month, etc., refer to an area C in fig. 3, the first background image may include electric quantity information of 77%, refer to an area D in fig. 3, the first background image may further include at least one shortcut start icon, such as a shortcut start icon for turning on a flashlight, a shortcut start icon for making a call, etc., so that a user may quickly start some commonly used functions. Of course, in practical applications, the first background image may further include other information, and this is not specifically limited in this embodiment of the present invention. The display driving chip may superimpose the time image and the pre-stored first background image, so that a composite image may be obtained, as shown in fig. 4.
When the date information is included in the first background image, before this step, the display driving chip may further perform steps including: receiving a first background image sent by an application processor, wherein the first background image is generated and obtained according to current date information when the date of the application processor changes; and replacing the second background image stored before the date is changed with the first background image.
The application processor can be awakened when the date changes, then generates a first background image according to the current date information, and then the application processor can send the first background image to the display driving chip, and then the display driving chip can replace a second background image which is stored before the date changes with the updated first background image.
For example, the display driver chip stores a second background image corresponding to day 5/20, when the date changes from day 5/20 to day 5/21, the application processor may be awakened, and then generate a first background image according to date information corresponding to day 5/21, and then the application processor may send the first background image to the display driver chip, and then the display driver chip may replace the second background image corresponding to day 5/20 stored before the date changes with the first background image corresponding to day 5/21, so that the area B in fig. 3 may be updated.
When the first background image includes the electric quantity information, before this step, the display driving chip may further perform the following steps including: receiving a first background image sent by an application processor, wherein the first background image is generated and obtained according to current electric quantity information when the electric quantity of the application processor changes; and replacing the second background image stored before the change of the electric quantity with the first background image.
The application processor can be awakened when the electric quantity changes, then a first background image is generated according to the current electric quantity information, the application processor can send the first background image to the display driving chip, and the display driving chip can replace a corresponding second background image before the stored electric quantity changes with the updated first background image.
For example, the display driver chip stores a second background image corresponding to 78% of electric quantity, when the electric quantity changes from 78% to 77%, the application processor may be awakened, and then generates a first background image according to date information corresponding to 77% of electric quantity, and then the application processor may send the first background image to the display driver chip, and then the display driver chip may replace the second background image corresponding to 78% of electric quantity stored before the electric quantity changes with the first background image corresponding to 77% of electric quantity, so that the area C in fig. 3 may be updated.
In a specific application, the first background image may be stored in a RAM (random access memory) of the display driver chip until the date and/or the power is changed again.
Step 205: and when the timing is started from the initial moment and the preset time length is passed, the display driving chip outputs the synthesized image for displaying.
In the embodiment of the present invention, since the sending time difference between the control command and the target time image information is very short, when the display driver chip receives the control command or receives the target time image information sent by the application processor, the display driver chip may start timing from the current start time through an internal crystal oscillator, and when a preset time length elapses from the start time, the display driver chip may output a composite image corresponding to the elapse of the preset time length from the start time to the display panel, and the display panel may display the composite image.
Step 206: and the display driving chip takes the moment obtained by adding the starting moment and the preset duration as the starting moment, takes the time image information corresponding to the time image as the target time image information, and returns to the step of determining the image updating information corresponding to the preset duration from the starting moment.
After the display driver chip outputs the time image, the display driver chip may use a time obtained by adding the start time and the preset time length as a new start time, use time image information corresponding to the time image as new target time image information, and then may return to the step of determining image update information corresponding to the time when the preset time length elapses from the start time. Therefore, the application processor only needs to send target time image information to the display driving chip once at the starting time, and the subsequent display driving chip can perform self-updating of the time image in a circulating mode, so that the application processor does not need to be kept in a working state all the time, and the power consumption of the mobile terminal is reduced.
In the embodiment of the invention, when the display driving chip receives the target time image information sent by the application processor, it is possible to determine image update information corresponding to the lapse of a preset time period from the start time, then, a time image corresponding to the preset time duration from the starting time can be generated according to the target time image information and the image updating information, then the time image and a pre-stored first background image can be synthesized to obtain a synthesized image, when the preset time length is passed after the time is counted from the starting time, the display driving chip can output the composite image for display, and then the display driving chip can take the time obtained by adding the starting time and the preset time length as a new starting time, take the time image information corresponding to the time image as new target time image information, and return to the step of determining the image updating information corresponding to the time when the preset time length passes from the starting time. Therefore, the application processor only needs to send target time image information to the display driving chip once at the starting time, and the subsequent display driving chip can perform self-updating of the time image in a circulating mode, so that the application processor does not need to be kept in a working state all the time, and the power consumption of the mobile terminal is reduced.
