Detailed Description
Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as detailed in the accompanying claims.
Fig. 1 is a flowchart illustrating a method of reducing display power consumption according to an exemplary embodiment of the present disclosure. Referring to fig. 1, the method provided in the present embodiment is applied to a touch terminal, and the method may include:
S101, responding to touch operation of a target image currently displayed by the touch terminal, and determining position information of a touch area corresponding to the touch operation on a display screen according to original touch data corresponding to the touch operation.
Specifically, the method provided in this embodiment may be executed by a central processing unit CPU in the touch terminal, or may be executed by a display driver in the touch terminal. In this embodiment, this is not limited. In addition, when the method is executed through the display driver, data transmission between the CPU and the display driver can be reduced, the cost of the CPU is saved, and the burden of the CPU is reduced.
When a touch operation is detected by a touch sensor in the touch terminal, a touch event is reported to the CPU. Further, when the method is performed by the CPU, the CPU may perform the method upon detecting a touch event reported by the touch sensor. In addition, when the method is performed by the display driver, the display driver may perform the method upon receiving a notification message issued by the CPU, and the notification message may be a notification message sent to the display driver when the CPU detects a touch event reported by the touch sensor.
In addition, the original touch data corresponding to the touch operation may be the original data reported by the touch sensor. Further, the position information of the touch area corresponding to the touch operation on the display screen may be the pixel coordinates of each touch point in the touch area corresponding to the touch operation on the display screen or the pixel coordinates of the boundary touch point of the touch area corresponding to the touch operation on the display screen. In the present embodiment, this is not limited.
In specific implementation, the touch area may be determined firstly based on the original touch data (the related process may be referred to in the description of the related technology), further, the touch coordinates of each touch point in the touch area corresponding to the touch operation on the touch screen may be mapped onto the display screen (the related specific implementation principle of the mapping may be referred to in the description of the related technology), the pixel coordinates of each touch point in the touch area corresponding to the touch operation on the display screen are obtained, and finally, the pixel coordinates of each touch point in the touch area corresponding to the touch operation on the display screen are determined as the position information of the touch area corresponding to the touch operation on the display screen, or the pixel coordinates of the boundary touch point in the touch area corresponding to the touch operation on the display screen are determined as the position information of the touch area corresponding to the touch operation on the display screen.
S102, determining an updated image for updating the target image based on the position information; the resolution of the updated image is equal to the physical resolution of the display screen, and the pixel value of each pixel point in the first area corresponding to the touch area in the updated image is 0.
In particular, the target image may be scaled first so that the resolution of the scaled target image is equal to the physical resolution of the display screen. Further, updating pixel values of all pixel points in a first area corresponding to the touch area in the scaled target image to 0 to obtain an updated image.
The first region corresponding to the touch region in the target image refers to a region in which position information matches position information of the touch region corresponding to the touch operation on the display screen. For example, when the position information of the touch area corresponding to the touch operation on the display screen is the pixel coordinates of each touch point in the touch area corresponding to the touch operation on the display screen, at this time, the first area may be an area configured by pixel points in the target image whose pixel coordinates are equal to the first pixel coordinates (the pixel coordinates of each touch point in the touch area corresponding to the touch operation on the display screen). For another example, when the position information of the touch area corresponding to the touch operation on the display screen is the pixel coordinate of the boundary touch point in the touch area corresponding to the touch operation on the display screen, at this time, the first area may be an area surrounded by the pixel coordinate of the target image equal to the pixel coordinate of the second pixel coordinate (the pixel coordinate of the boundary touch point in the touch area corresponding to the touch operation on the display screen).
And S103, updating the target image by using the updated image, so that the display panel of the touch terminal turns off the pixel light emitting units corresponding to the target area when the updated image is displayed.
When the method is executed by the CPU, the specific implementation procedure of this step may be to issue the updated image to a display driver, so as to instruct the display driver to send the updated image to the display panel for display.
When the method is executed by a display driver, the specific implementation process of the step may be that the updated image is sent to the display panel for display.
The display panel includes pixel light emitting units arranged in an array, and when the display panel displays the updated image, the pixel value of each pixel point in the first area is 0, so that the pixel light emitting unit corresponding to the first area (the pixel light emitting unit whose position matches that of the first area) is turned off and does not emit light when the display panel is actually displayed.
According to the method provided by the embodiment, in response to the touch operation of the target image currently displayed by the touch terminal of the device, the position information of the touch area corresponding to the touch operation on the display screen is determined according to the original touch data corresponding to the touch operation, and the update image for updating the target image is determined based on the position information; the updated image is obtained, wherein the resolution of the updated image is equal to the physical resolution of the display screen; and the pixel value of each pixel point in the first area corresponding to the touch area in the updated image is 0, and the target image is updated to the updated image by using the updated image, so that the pixel light-emitting unit corresponding to the first area is turned off when the display panel of the touch terminal of the device displays the updated image. Thus, the pixel light emitting units corresponding to the touch area can be turned off, and the purpose of reducing power consumption is achieved. In addition, since the turned-off pixel light emitting unit is the pixel light emitting unit corresponding to the touch area, that is, the partial image not displayed is the partial image blocked by the user, the user experience is not affected at this time.
Fig. 2 is a flowchart illustrating a method of reducing display power consumption according to an exemplary embodiment of the present disclosure. Referring to fig. 2, on the basis of the above embodiment, determining an update image for updating the target image based on the position information includes:
S201, generating a touch image for showing the touch area according to the position information and the physical resolution of the display screen; the resolution of the touch image is equal to the physical resolution, and the pixel value of each pixel point in a second area matched with the position information in the touch image is equal to a first preset value.
Specifically, when the position information of the touch area corresponding to the touch operation on the display screen is the pixel coordinates of each touch point in the touch area corresponding to the touch operation on the display screen, at this time, the second area may be an area formed by pixel points in the touch image, where the pixel coordinates are equal to the first pixel coordinates (the pixel coordinates of each touch point in the touch area corresponding to the touch operation on the display screen). When the position information of the touch area corresponding to the touch operation on the display screen is the pixel coordinate of the boundary touch point in the touch area corresponding to the touch operation on the display screen, at this time, the second area may touch an area surrounded by the pixel points in the image, where the pixel coordinate is equal to the second pixel coordinate (the pixel coordinate of the boundary touch point in the touch area corresponding to the touch operation on the display screen).
In addition, the first preset value is set according to actual needs. In this embodiment, a specific value of the first preset value is not limited. For example, in one embodiment, the first preset value may be 0.
Further, in an embodiment, a pixel value of any pixel point in the touch image except the second area may be equal to the second preset value. Wherein the second preset value is different from the first preset value. For example, in one embodiment, the second preset value may be 255.
For example, fig. 3 is a schematic diagram of a touch operation illustrated by the present disclosure according to an exemplary embodiment. Fig. 4 is a schematic diagram of a touch image corresponding to the embodiment shown in fig. 3. Referring to fig. 3 and 4, the touch image is used to show the touch area.
S202, synthesizing the updated image based on the touch image and the target image.
Fig. 5 is a schematic diagram of an implementation of a composite updated image shown in accordance with an exemplary embodiment of the present disclosure. Referring to fig. 5, in a specific implementation, the process of synthesizing the updated image may include:
(1) For any updated pixel point in a target area corresponding to the second area in the updated image, determining the pixel value of the updated pixel point as 0;
(2) And determining the pixel value of a target pixel point corresponding to the updated pixel point in the target image as the pixel value of the updated pixel point aiming at any updated pixel point except the target area in the updated image.
Specifically, the target pixel point corresponding to the updated pixel point in the target image refers to a pixel point whose pixel coordinate is equal to the pixel coordinate of the updated pixel point.
The method provided by the embodiment provides a method for determining an update image based on the position information, by which an update image with a shielding area (the first area) can be generated, and further, a target image can be updated by using the update image, so that when the display panel of the touch terminal displays the update image, a pixel light emitting unit corresponding to the shielding area is turned off, and the purpose of reducing display power consumption is achieved.
A more specific embodiment is given below to illustrate the technical solution of the present disclosure in detail:
Fig. 6 is a flowchart illustrating a method of reducing display power consumption according to an exemplary embodiment of the present disclosure. Referring to fig. 6, the method provided in the present embodiment is applied to a touch terminal, and the method is performed by a display driver on the touch terminal, and the method may include:
S601, responding to touch operation of a target image currently displayed by the touch terminal, acquiring original touch data corresponding to the touch operation from a touch driver, and determining position information of a touch area corresponding to the touch operation on a display screen according to the original touch data corresponding to the touch operation.
