A control method, an apparatus, an electronic device, and a storage medium of a touch screen according to embodiments of the present application are described below with reference to the accompanying drawings.
The embodiment of the application provides a control method of a touch screen, aiming at the problems that in the related art, the OLED screen is used for screen-off display, the cost is high, and the OLED screen cannot be popularized and used.
According to the control method of the touch screen, the state conversion layer is arranged below the message popup layer, the popup instruction of the message popup is received when the touch screen is turned off, the backlight is turned on, the state conversion layer is converted into the background state from the transparent state, and the message popup is rendered on the state conversion layer, so that only the region where the message popup is located is left in a user visible region on the touch screen, screen turn-off display is achieved, screen turn-off display can be achieved without using an OLED screen, the cost is low, and the method can be popularized and used.
Fig. 1 is a schematic flowchart of a control method of a touch screen according to an embodiment of the present application.
The control method of the touch screen in the embodiment of the present application may be implemented by a device controlled by the touch screen provided in the embodiment of the present application, and the device may be configured in an electronic device, such as a mobile phone, a tablet computer, a car machine, and the like, so as to implement a screen-off display by controlling state transitions of a state conversion layer under a backlight and a message popup.
As shown in fig. 1, the control method of the touch screen includes:
After the application on the electronic device receives the message, the application may generate a pop-up instruction for the message popup, and then the electronic device may receive the pop-up instruction for displaying the message popup on the touch. The message popup may be a dialog box or a message notification, and the popup instruction is used to indicate that there is a message popup to be displayed on the touch screen, and the popup instruction includes but is not limited to: the content of the message, the size of the message pop, etc.
For example, the vehicle touch screen refers to a touch screen of a car machine, and the car machine may install a plurality of applications, such as an application for playing songs, a navigation application, a chat application, a parking assistance application, and the like. In addition, the car machine can be connected with a mobile phone, a palm computer and the like to synchronously receive messages of the mobile phone, the palm computer and the like. After the application program on the car machine receives the message, the car machine can receive a pop-up instruction for displaying the message popup window on the touch screen.
In general, the touch screen is in an on state, and then a backlight of the touch screen is in an on state, so that a user can see contents displayed on the touch screen.
In this embodiment, the touch screen may also be turned off. Specifically, the touch screen may be automatically turned off according to the setting, or the user may turn off the touch screen through a key on the vehicle for turning off the touch screen. Here, the key for turning off the touch screen may also be used for turning on the touch screen.
For example, if it is preset that the touch screen is turned off between 9 pm and 12 pm, the backlight of the touch screen may be automatically turned off in this time period, that is, the touch screen is turned off, so that the touch screen is in a standby state. For another example, when the touch screen is in the on state, if the user triggers a key for turning off the touch screen, the backlight of the touch screen is turned off, so that the touch screen is in the standby state.
It can be understood that, after the backlight of the touch screen is turned off, the brightness of the touch screen is zero, and the user cannot see the content displayed on the touch screen.
Therefore, when a message popup is about to pop up, the touch screen may be in a standby state or an open state. Based on this, the current state of the touch may be detected, and specifically, the current state of the touch screen may be determined according to a value of a preset field for identifying the state of the touch screen. For example, if the value is 00, the touch screen is in a standby state, and if the value is 01, the touch screen is currently in an on state.
And 103, responding to the current state of the touch screen in a standby state, and sending a control instruction for starting a backlight lamp of the touch screen.
When the current state of the touch screen is in a standby state, namely the touch screen is in a screen-off state, in order to display a message popup, a backlight of the touch screen needs to be turned on. At this time, a control instruction for turning on the backlight of the touch screen is given, so that the backlight is turned on according to the control instruction. If the backlight is turned on, the content displayed on the touch screen, such as an application logo, is displayed.
And 104, converting the state conversion layer displayed on the touch screen from a transparent state to a background state.
In this embodiment, a state conversion layer may be rendered on the touch screen in advance, and a default state of the state conversion layer is a transparent state. Here the state-change layer can be switched from a transparent state to a background state. Wherein, the background state can be black, that is, the state changing layer changes from transparent to black. Then the state translation layer may block the content of the level rendered below it after transitioning to the background state.
And 105, rendering a message popup window on the state conversion layer based on the popup instruction. And rendering a message popup window on the state conversion layer according to the popup instruction after the backlight lamp of the touch screen is started and the state conversion layer displayed on the touch screen is converted from a transparent state to a background state.
In this embodiment, the message popup corresponds to one layer, the state translation layer corresponds to one layer, and rendering the message popup on the state translation layer means rendering the message popup on a level of the state translation layer so that the level where the message pops up is above the level of the state translation layer.
Because the backlight of the touch screen is turned on, the user can see the content displayed on the touch screen, and because the state conversion layer is in the background state currently and the level of the message popup window is higher than that of the state conversion layer, the message popup window is rendered on the state conversion layer, and the state conversion layer can block the display of other content on the touch screen except the message popup window, such as the display of an application program identifier.
In this embodiment, the rendering of the message popup on the state translation layer is to avoid that the state translation layer blocks the message popup and blocks display contents outside the message popup, so as to achieve the purpose of displaying only the message popup. Therefore, when the message popup is rendered on the state conversion layer, the area visible to the user is only the area where the message popup is located, and screen-off display is achieved.
In the embodiment of the application, the state conversion layer is arranged below the message popup layer, if a popup instruction for displaying the message popup on the touch screen is received when the touch screen is turned off, the state conversion layer is converted into a background state from a transparent state by turning on the backlight lamp, and the message popup is rendered on the state conversion layer, so that only the region where the message popup is located is left in a user visible region on the touch screen, screen turn-off display is realized, and screen turn-off display can be realized without using an OLED screen.
In practical applications, when there is a message popup to be displayed, the touch screen may be in an open state. In order to avoid the state conversion layer from affecting the normal display of the touch screen, in an embodiment of the present application, the method for controlling the touch screen further includes: and responding to the current state of the touch screen in an opening state, sending a control instruction for closing the state conversion layer, closing the state conversion layer according to the control instruction, and displaying a message popup window on the touch screen.
That is, when there is a message popup to be displayed, if the touch screen is in an open state, the state conversion layer is removed, and the message popup is displayed on the touch screen.
In the embodiment of the application, a control instruction for closing the state conversion layer is sent in response to the current state of the touch screen being in the open state, and the message popup window is displayed on the touch screen.
In practical applications, when the touch screen is normally displayed, application identifiers, such as icons and names of the applications, are displayed. To enhance the effectiveness of the screen-out display, in one embodiment of the present application, the level of the state translation layer is lower than the level of the message popup, and the level of the state translation layer is higher than the level of the application logo display layer.
The application program identifier display layer is a layer for displaying application program identifiers such as icons and names.
Specifically, a level mark is assigned to each layer, and a priority policy is stored in advance for the level marks. When a plurality of hierarchies are simultaneously present, the priority of each hierarchy is compared, and the higher the priority of the hierarchy is, the lower the priority of the hierarchy is.
In this embodiment, the level of the message popup is higher than that of the state translation layer, and the level of the state translation layer is higher than that of the application identifier display layer, as shown in fig. 2, fig. 2 is a schematic diagram of a level lower than that provided in this embodiment. Then, when displayed, the message popup is above the state translation layer, which is above the application identification.
In the embodiment of the application, the level of the state conversion layer is lower than that of the message popup window, and the level of the state conversion layer is higher than that of the application program identification display layer. Therefore, the message popup is displayed when the current state of the touch screen is in a standby state, and the level of the state conversion layer is higher than that of the application program identification display layer and lower than that of the message popup, so that the display of the message popup is not influenced, the display of the application program identification is shielded, and the screen-off display effect is improved.
In order to further improve the effect of the screen-off display, in an embodiment of the present application, when the screen-off display is performed, the brightness of the touch screen may also be adjusted according to the brightness information of the environment. Fig. 3 is a schematic flowchart of another control method for a touch screen according to an embodiment of the present disclosure.
As shown in fig. 3, the method further comprises:
In this embodiment, an optical sensor may be disposed near the touch screen, and the brightness of the current environment is collected in real time through the optical sensor, so as to obtain the brightness information of the environment.
And step 302, adjusting the brightness of the touch screen according to the brightness information of the environment.
In this embodiment, when the ambient brightness is low, the brightness of the backlight is reduced to reduce the brightness of the touch panel in order to reduce light leakage. When the brightness of the environment is higher, the brightness of the backlight lamp can be increased to increase the brightness of the touch screen, so that the interface is clearer, and a better screen-off display effect is achieved.
In the embodiment of the application, the brightness of the touch screen can be adjusted according to the brightness information of the environment by detecting the brightness information of the environment. Therefore, the brightness of the touch screen is dynamically adjusted according to the brightness of the environment, and the screen-off display effect can be further improved.
In order to improve the accuracy of adjusting the brightness of the touch screen, when the brightness of the touch screen is adjusted according to the brightness information of the environment, in an embodiment of the present application, the brightness of the touch screen may be adjusted according to the size relationship between the brightness of the environment and a preset threshold.
In this embodiment, a first preset threshold and a second preset threshold are preset, where the second preset threshold is greater than the first preset threshold, and the first preset threshold and the second preset threshold may be set according to actual needs and experience.
After the brightness information of the environment is obtained, the brightness information of the environment is compared with a first preset threshold and a second preset threshold. If the brightness information of the environment is smaller than the first preset threshold, it is indicated that the brightness of the environment is relatively low, and in order to reduce light leakage, the brightness of the backlight may be reduced to reduce the brightness of the touch screen.
If the brightness information of the environment is greater than the second preset threshold, which indicates that the brightness of the environment is relatively high, the brightness of the touch screen may be increased, specifically, an adjustment amount of the brightness of the touch screen may be determined according to a difference between the brightness information of the environment and the second preset threshold, where the larger the difference is, the larger the adjustment amount of the brightness of the touch screen is.
If the brightness information of the environment is greater than or equal to the first preset threshold and less than or equal to the second preset threshold, the brightness of the touch screen can be kept unchanged.
In the embodiment of the application, when the brightness of the touch screen is adjusted according to the brightness information of the environment, if the brightness information of the environment is smaller than a first preset threshold, the brightness of the touch screen is reduced, and if the brightness information of the environment is larger than a second preset threshold, the brightness of the touch screen is improved, wherein the second preset threshold is larger than the first preset threshold. Therefore, the brightness of the touch screen can be accurately adjusted by setting the first preset threshold and the second preset threshold according to the comparison result of the brightness information of the environment and the first preset threshold and the second preset threshold, and the accuracy of the brightness adjustment of the touch screen is improved.
In order to avoid that a user mistakenly triggers an application program when the touch screen is closed, in one embodiment of the application, when the current state of the touch screen is in a standby state, the backlight is closed, the touch screen is kept in a touch detection state, and meanwhile, the state conversion layer is opened, so that the state conversion layer shields an application program identifier displayed in the touch screen.
The touch screen is in a touch detection state, which means that the touch operation can be monitored when the touch screen is in a standby state.
In this embodiment, when the current state of the touch screen is in the standby state, the backlight is turned off to make the brightness of the touch screen be 0, so that a user cannot see contents displayed on the touch screen, and the touch screen keeps monitoring of touch operations, and simultaneously the state conversion layer is turned on to shield an application program identifier displayed in the touch screen, thereby preventing the user from mistakenly triggering the application program.
That is to say, when the touch screen is in a standby state, the state conversion layer is opened to shield the application program identifier in the touch screen and prevent the application program from being triggered.
Therefore, in the embodiment of the application, the state conversion layer can be combined with the backlight to realize screen-off display, and can shield the application program identifier when the touch screen is closed, so that the application program in the touch screen is prevented from being triggered.
In the embodiment of the application, when the current state of the touch screen is in a standby state, the backlight lamp is turned off, the touch screen is kept in a touch detection state, and the state conversion layer is turned on at the same time, so that the state conversion layer shields the application program identifier displayed in the touch screen. Therefore, when the touch screen is closed, the touch screen can monitor the trigger operation and can prevent the application program from being triggered.
In order to improve the use experience of the touch screen, in an embodiment of the application, when the message popup command is received, if the touch screen is closed, the touch screen can be awakened, so that the touch screen can display normally. Fig. 4 is a schematic flowchart of another control method for a touch screen according to an embodiment of the present application.
As shown in fig. 4, in response to the current state of the touch screen being in the standby state, the method may further include:
In this embodiment, the automatic wake-up touch screen may be preset, or may be woken up according to the operation of the user on the relevant key.
For example, if the touch screen is preset to be turned off between 9 pm and 12 pm, a wake-up command may be received to wake up the touch screen when the time exceeds 12 pm. For another example, the user triggers a key on the vehicle for closing the touch screen, and then a wake-up instruction is generated according to the operation of the user, so that the wake-up instruction can be obtained to wake up the touch screen.
And step 402, controlling the backlight lamp to be turned on according to the awakening instruction, and turning off the state conversion layer.
After the wake-up instruction is acquired, the backlight lamp can be controlled to be turned on according to the wake-up instruction, so that the brightness of the touch screen is larger than 0. Because the application program identifier is arranged above the display layer and the state conversion layer is arranged below the message popup window, in order to normally display the application program, the state conversion layer can be closed, namely the state conversion layer is removed, so that the application program identifier is prevented from being shielded.
And then, the message popup and the application program identification can be displayed on the touch screen according to the corresponding level. In this embodiment, if the level of the message popup is higher than the level of the application identifier, the message popup is displayed above the application identifier.
In the embodiment of the application, when the current state of the touch screen is in a standby state, a wake-up instruction can be received, the backlight lamp is controlled to be turned on according to the wake-up instruction, and the state conversion layer is turned off. Therefore, when the touch screen is awakened, the state conversion layer is closed, and the layer below the state conversion layer is prevented from being shielded.
