Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. 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.
In an embodiment of the present invention, a display device 01 is provided, and in the embodiment of the present invention, the display device 01 is an OLED (Organic Light Emitting Diode) display device. As shown in fig. 1, the display device 01 includes a processor 10, a display 20, and a Driver Integrated Circuit (DIC) 30.
In addition, the control method of the display device 01 includes, as shown in fig. 2, S101 to S104.
S101, the processor 10 receives the first instruction, and inputs the static image 100 as shown in fig. 3a, at least one dynamic image 200 as shown in fig. 3b, and the initial display position of each dynamic image 200 to the DIC 30.
Wherein the display area of the moving image 200 is smaller than the display area of the still image 100. In this case, when the moving image 200 is superimposed on the still image 100, the still image 100 may be a background image, and the moving image 200 may be positioned in front of the background image as a foreground image.
It should be noted that before executing S101, a communication protocol, such as MIPI (mobile industry processor interface) or SPI (serial peripheral interface), may be established between the processor 10 and the DIC 30. Thereby enabling the processor 10 to input information such as the still image 100, the moving image 200, and the initial display position of the moving image 200 to the DIC30 through the above-described interface.
When the processor 10 receives the first instruction, the display device 01 enters the AOD display mode. In this case, the still image 100 may be an image in which at least a part of the display screen 20 is displayed at all times and the content does not change. That is, the display content of the still image 100 as the background image does not change after the display device 01 enters the AOD.
The moving image 200 is an image in which a feature such as a position (or a shape) changes with time, which is displayed on the still image 100 by superimposing the display screen 20 on the still image 100 after the display device 01 enters the AOD.
For example, in some embodiments of the present application, the static image 100 is a dial as shown in fig. 3 a. Based on this, the at least one dynamic image 200 comprises an hour hand, a minute hand and a second hand as shown in fig. 3 b. In this case, when the display device 01 enters the AOD, the positions of the hour hand, minute hand, and second hand as the moving image 200 change with time.
Before S101, the user can set the style of the dial as the still image 100 and the style of the hour hand, minute hand, or second hand as the moving image 200.
For example, in fig. 3a, the dial is circular. In other embodiments of the present application, the dial may also be a square, a diamond, etc., which is not limited in this application. In addition, the present application does not limit the styles of the hour hand, minute hand or second hand, such as length, thickness and the like.
In other embodiments of the present application, the static image 100 may also be a map, and the dynamic image 200 may be an identification of a location of the user in the map. In this case, when the display device 01 enters the AOD, the location of the user in the map as the moving image 200 changes over time.
The above is merely an illustration of the still image 100 and the moving image 200. Other examples are not described in detail herein. For convenience of illustration, the following description will be given taking a dial as the still image 100 and an hour hand, a minute hand, or a second hand as the moving image 200.
In this case, the hour hand, minute hand, or second hand is superimposed on the dial at the initial display position, and the display screen 10 displays the same time as the processor 10 executes S101.
In addition, in the case where the still image 100 is a dial and the at least one moving image 200 includes an hour hand, a minute hand, and a second hand, and when the processor 10 receives the first instruction during the execution of the step S101, the method for controlling the display device 01 further includes:
In addition, for example, in some embodiments of the present application, when the display device 10 is a mobile phone or a tablet computer, after the display device 01 enters the AOD, as shown in fig. 4a, a portion of the display screen 20 in the display device 10, for example, a middle display area, displays a time clock image, and another portion of the display area does not display a picture, so as to achieve the purpose of reducing power consumption.
Alternatively, in other embodiments of the present application, as shown in fig. 4b, when the display device 10 is mounted on the band 40 to form the wearable device 02, the display screen 20 of the display device 10 displays the time clock image in almost all display areas. At this time, the wearable device 02 is used only for display, and does not perform other controllable operations such as an operation of referring to information or the like.
S102, the processor 10 enters the sleep state, and the DIC30 updates the actual display position of the moving image 200 in real time according to the initial display position of the moving image 200.
After the processor 10 has executed the above-mentioned S101, it enters the sleep state. At this point, processor 10 need not send time-dependent display data to DIC30 in real-time.
Next, DIC30 may update the actual display position of the hour, minute, or second hand, respectively, in real-time based on the initial display position of the hour, minute, or second hand as dynamic image 200 input by processor 10.
For example, in some embodiments of the present application, the DIC30 described above includes a clock 301 as shown in FIG. 5.
Based on this, the above S102 may include: the clock 301 of the DIC30 counts time, and the DIC30 acquires the actual display position of the moving image 200 based on the timing result and the initial display position of the moving image 200.
The clock 301 (CLK) of the DIC30 may include a crystal 3011 disposed inside the DIC 30. The crystal oscillator 3011 oscillates within its tension limits at a frequency that depends on the crystal cutting parameters of the crystal oscillator itself and the amount of tension the crystal is subjected to.
The clock 301 further includes a Counter (Counter)3012 and a Holding Register (Holding Register)3013 connected to the crystal 3011. Each oscillation of the crystal 3011 causes the counter to decrement by 1. When the counter 3012 is decremented to 0, an interrupt is generated and the counter 3012 is reloaded with the initial value from the holding register 3013.
Each interrupt is referred to herein as a Clock Tick (Clock Tick). In this case, the number of interrupts of the clock 301 per second, that is, the inherent number of interrupts, may be set for the purpose of time counting.
On this basis, when the still image 100 is a dial, the at least one moving image 200 includes an hour hand, a minute hand, and a second hand, and the processor 10 inputs the display position of the intersection 21 of the hour hand, the minute hand, and the second hand to the DIC30 in the above S101, the DIC30 acquiring the actual display position of the moving image 200 based on the timing result and the initial display position of the moving image 200 includes:
first, the DIC30 obtains the rotation angles of the hour hand, minute hand, and second hand around the intersection 21 from the clock timing result.
For example, according to the rotation rule of the second hand, the minute hand and the hour hand, the second hand can rotate 6 degrees at a time; the minute hand rotates 6 degrees per minute; the hour hand is turned 30 ° per hour. The DIC30 then calculates the actual rotation angle of the second, minute and hour hands based on the timing result of its internal clock.
Illustratively, DIC30 is clocked according to its internal clock for 2 seconds. At this time, the second hand is rotated by 12 ° about the intersection point 21 with respect to the initial position. The minute hand and hour hand are not rotated with respect to the initial position.
Then, the DIC30 determines the actual display positions of the second hand, minute hand, and hour hand, respectively, from the calculated actual rotation angle.
S103 and DIC30 superimpose moving image 200 on still image 100 according to the actual display position of moving image 200, thereby generating superimposed image 300 as shown in fig. 3 c.
S104 and DIC30 drive display screen 20 to display superimposed image 300.
As described above, in the control method of the display apparatus 01 according to the embodiment of the present application, after the processor 10 executes S101, the processor 10 enters the sleep state immediately after receiving the first instruction and inputting the static image 100, the at least one dynamic image 200 and the initial display position of each dynamic image 200 to the DIC 30.
Based on this, after the processor 10 enters the sleep state, the processor 10 does not need to send the display data related to the moving image 200 to the DIC30 in real time, thereby effectively reducing the power consumption of the processor 10.
Further, after the processor 10 is hibernated, the DIC30 may update the actual display position of the moving image 200 in real time according to the received initial display position of the moving image 200, and superimpose the moving image 200 on the still image 100 according to the actual display position of the moving image 200 to generate the superimposed image 300.
In this way, DIC30 drives display screen 20 to display superimposed image 300 as described above, thereby ensuring that display screen 20 displays moving image 200, such as a rotating hour, minute or second hand, as a function of time, even when processor 10 is in a sleep state.
As can be seen from the above, when the processor 10 enters the sleep state, the DIC30 may update the actual display position of the moving image 200 in real time according to the timing result of the internal clock. However, since the inherent interruption times of the clock have errors, for example, the preset inherent interruption times of the clock is 600 times per second, and the actual inherent interruption times of the clock may be 601 times per second or 602 times per second, the timing result of the clock has errors.
Thus, after the timing errors are accumulated for a period of time, the actual display position of the moving image 200 updated by the DIC30 in real time may deviate, for example, such that the final display time of the display screen 20 may not match the actual display time.
In order to solve the above problem, after the above S101 is executed and the processor 10 enters the sleep state, the method provided by the embodiment of the present application is as shown in fig. 6, and further includes S201 to S202.
At intervals of a predetermined time, processor 10 receives a second instruction to provide rectified images to DIC 30S 201.
S202, DIC30 drives display 20 to display the corrected image.
In S201, after the processor 10 receives the second instruction, the processor 10 stops the sleep state and enters the operating state. The processor 10 that is now in operation needs to send display data relating to the moving image 200, i.e., the above-described rectified image, to the DIC30 in real time.
For example, the corrected image may be an image in which the time represented by the combination of the hour hand, minute hand, or second hand is the same as the actual time (e.g., beijing time) in the image displayed on the display screen 20.
Illustratively, the predetermined time is 3min to 10 min. When the above-mentioned preset time is less than 3min, the time for which the processor 10 is in the sleep state is too short, so that the effect of reducing power consumption is reduced.
Alternatively, when the preset time is longer than 10min, the sleep time of the processor 10 is too long, and the accumulated clock error value in the DIC30 is large, so that the time of the user viewing the overlay image 300 displayed on the display screen 20 before the display screen 20 displays the corrected image has a large error from the actual time.
Based on this, in some embodiments of the present application, the preset time may be 3min, 4min, 5min, 6min, 7min, 8min, 9min, and 10 min.
In addition, when the static image 100 is a dial and the at least one dynamic image 200 includes an hour hand, a minute hand, and a second hand, and when the processor 10 receives a second instruction every preset time, the method further includes:
the processor 10 acquires the network time and generates the corrected image according to the network time.
In this case, the corrected image includes the dial, hour hand, minute hand, and second hand, and the time when the hour hand, minute hand, and second hand are combined on the dial is the same as the network time.
The network time may be an actual time acquired by the processor 10 after connecting to the communication network, for example, beijing time.
On this basis, DIC30 is shown in FIG. 5, and further includes memory 302. Based on this S101, the method further includes:
the memory 302 of the DIC30 stores the static image 100, the at least one dynamic image 200, and the initial display position of each dynamic image 200 for the purpose of obtaining the above information by the DIC 30.
The memory 302 may be various media capable of storing program codes, such as a ROM, a RAM, and the like.
The embodiment of the application provides a wearable device 02. The wearable device comprises the display device 01.
As can be seen from the above, the display device 01 includes the processor 10, the display 20, and the DIC30 as shown in FIG. 1.
In addition, the display device 01 includes a main board 40. The processor 10 is mounted on the motherboard 40.
The DIC30 is disposed in a non-display area of the display 20, i.e., an area other than an Active Area (AA) of the display 20. The DIC30 is electrically connected to the processor 10 through a Flexible Printed Circuit (FPC).
In this case, the FPC may be bent to dispose the main board 40 and the processor 10 disposed on the main board 40 on the non-display side of the display screen 20.
The processor 10 is configured to receive a first instruction and input the still image 100, the at least one moving image 200, and an initial display position of each moving image 200 to the DIC 30.
The DIC30 is configured to update the actual display position of the moving image 200 in real time according to the initial display position of the moving image 200 after the processor 10 enters the sleep state, and superimpose the moving image 200 onto the still image 100 to generate the superimposed image 300.
The display screen 10 is configured to perform image display under the driving of the DIC 30.
