Technical Field

Background
Portable terminal devices such as smart phones and tablet computers have become indispensable tools for people. In order to save the electric quantity of the terminal equipment, the terminal equipment can enter a rest screen standby state when not in a use state. In the screen-off standby state, the user may wake up the screen of the terminal device by pressing a bright screen key (e.g., Home key or power key) of the terminal device.
However, the position of the bright screen key of the terminal device is fixed, the user can only press the bright screen key at the fixed position to wake up the screen, which is inconvenient for the user to use, and the service life of the solid bright screen key is limited, and the key of the terminal device is easily damaged by pressing the solid bright screen key to wake up the screen. Because most of the current terminal devices adopt a touch screen as a display and control device, a scheme for waking up a screen of the terminal device by executing a certain bright screen gesture on the touch screen appears. For example, the user may wake up the screen of the terminal device by double-clicking on the touch screen or performing other specific bright screen gestures.
The touch screen of the terminal device realizes touch control by detecting capacitance or resistance change of a touched position on the touch screen, but the capacitance or resistance value of the touch screen of the terminal device is abnormal in detection in some cases. For example, when the terminal device is switched from the screen-on state to the screen-off state, the capacitance or the resistance of the touch screen may change, and at this time, if the user performs the screen-on gesture on the touch screen, the touch screen may not be correctly detected, so that the terminal device may not correctly respond to the screen-on operation, and the user experience is affected.

Detailed Description
The present application will be described in further detail with reference to the following drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the application and are not limiting of the application. It should be further noted that, for the convenience of description, only some of the structures related to the present application are shown in the drawings, not all of the structures.
In order to provide better use feeling for users, the screen occupation ratio of the current portable terminal device is larger, and a Touch Panel (TP) is mostly arranged in the area of the whole display screen, so that the display screen becomes the Touch screen as the input device of the terminal device. As shown in fig. 1, fig. 1 is a schematic front view of a terminal device, and in fig. 1, a touch panel is disposed in an area where a display screen 11 is located, so that a user can operate and control the terminal device by touching any position of the display screen 11.
The touch screen of the terminal equipment consists of a liquid crystal screen, a touch panel and a driving circuit, and a transparent cover plate for protecting the liquid crystal screen is covered on the liquid crystal screen and the touch panel. The touch panel is composed of a plurality of sensor nodes, as shown in fig. 2, and fig. 2 shows a schematic structural diagram of a touch screen of a terminal device. The liquid crystal screen 21 and the touch panel 22 are overlapped in area, the touch panel 22 is composed of a plurality of sensor nodes 23, each sensor node is connected with a driving circuit 24, and a protection panel 25 covers the liquid crystal screen 21, the touch panel 22 and the driving circuit. The touch panel 22 is divided into two structures, namely a capacitive structure and a resistive structure, and taking the currently commonly used capacitive structure as an example, each time a user touches a touch screen of the terminal device, a sensor node 23 in the touch panel 22 at a touch position detects that capacitance changes, so that the touch position of the user can be determined.
In order to save the electric quantity of the terminal device, the display screen of the terminal device is generally required to be in a screen-off state in a standby state of the terminal device, and the screen is turned on when a user triggers the screen to be turned on. At present, two terminal screen-lighting control methods exist, one of which is realized by pressing a screen-lighting key of an entity by a user, such as a Home key or a power key of a terminal device, but in this method, the user needs to press a key at a specific position, so that the operation of the user is limited, and the entity key is easy to damage. Another method is to preset a screen-brightening gesture, and when a user executes the screen-brightening gesture on the touch screen, the terminal device is controlled to brighten, but parameters of each sensor node in the touch panel change under certain conditions of the touch screen of the terminal device, which may cause inaccurate detection of the screen-brightening gesture of the user, and thus may not correctly respond to the screen-brightening operation of the user.
Fig. 3 is a flowchart of a first embodiment of a terminal bright screen control method provided in an embodiment of the present application, and as shown in fig. 3, the method provided in this embodiment includes:
The terminal screen-lighting control method provided by the embodiment of the application is applied to any terminal equipment with a touch screen, and the terminal equipment can automatically or manually close the display screen to enter a screen-off state. As can be seen from the touch screen structure shown in fig. 2, the touch screen of the terminal device is composed of two parts, namely, the liquid crystal display and the touch panel, and when the terminal device enters the screen-off state, the liquid crystal display is turned off, and the touch panel can still be in the working state.
Therefore, when the terminal device is in the screen resting state, the touch operation on the touch screen of the terminal device can be continuously detected. Each touch operation of the user on the touch screen is detected to obtain touch data, and the touch data at least comprises position information on the touch screen. By continuously detecting, a series of continuous or discontinuous touch operation data can be obtained, and the touch operation data can be formed into a touch data queue through the time of the touch operation data. To avoid the false screen-up of the terminal device, the screen-up operation performed by the user on the touch screen is generally a specific gesture combination, for example, a gesture of double-clicking or drawing a specific track on the touch screen. Therefore, only after the touch data of a certain time is detected, whether the touch data is a preset bright screen operation can be judged, so that the touch data of the touch screen needs to be continuously detected to obtain a touch data queue.
In this embodiment, the touch screen of the terminal device may be a capacitive touch screen or a resistive touch screen, or touch screens of different forms, where the types of touch data are different. Preferably, the touch screen is a capacitive touch screen.
For various reasons, when detecting touch data, a touch screen of a terminal device may have a large deviation from the first data or from several data. For example, after the terminal device turns off the screen, each sensor node on the touch panel has a certain noise influence in a short time, and at this time, if the user touches the touch panel, the detected touch data has a large error. For example, a sensor node on the touch panel, which is far away from the driving circuit, is also prone to have a detection error when triggered in a standby state. When the touch data has a large error, the terminal device considers the touch data as noise data or abnormal data, which may cause that the bright screen operation performed by the user on the touch screen of the terminal device cannot be correctly detected. For example, the screen-lighting gesture of the terminal device is double-click screen-lighting, that is, quickly clicking twice on the touch screen is the screen-lighting gesture, and if the operation of clicking the touch screen for the first time is considered to be abnormal data due to a large detection error, the terminal device considers that the user has only clicked once, and the screen-lighting of the terminal device is not triggered.
Through a lot of experiments and researches, it is found that only the first or the first few touch data detected by the touch panel in the standby state may have a large error, and the detection error will gradually decrease as the detection proceeds. Therefore, when the terminal device is in a screen-rest state, after a touch data queue on a touch screen of the terminal device is detected, the nth touch data can be used as the touch data to be determined, and the touch gesture corresponding to the nth touch data in the touch data queue is determined according to the touch data started from the nth touch data, where N is greater than or equal to 2. Touch data preceding the N-1 th touch data in the touch data queue may be ignored or discarded. Since the first N-1 touch data are ignored or discarded, the detection error of the touch data queue from the Nth touch data will not be too large, and thus detection abnormality will not be caused thereby. Each touch data in the touch data queue at least comprises touch position information, so that touch track information can be obtained according to the touch data queue started by the Nth touch data, and a corresponding touch gesture can be obtained according to the touch track information. N in the touch data queue may be set according to the performance of different touch screens, and for a touch screen with better response performance, N may be generally set to 2.
The touch data in the touch data queue may be continuous or discontinuous, for example, for a double-tap gesture, the corresponding touch data is not continuous. Touch data within a time interval, typically short, such as 1 second or 500 milliseconds, can thus be served as a touch data queue. If touch data is detected again within a certain time interval after one touch data is detected, the two touch data are considered as a touch data queue.
It should be noted that the value N in the touch data queue may be preset or obtained by real-time detection. And when the touch data are detected, sequentially judging the touch data, if the touch data are abnormal, continuously judging whether the subsequent touch data are abnormal until the touch data are normal, and taking the normal touch data as the Nth touch data. In addition, each touch data in the touch data queue may be detection data of one frame of the touch panel, and according to the detection principle of the touch panel, whether the data is abnormal or not is determined according to only the difference between two adjacent detection data. And taking the previous frame data of the touch panel as original data (raw data) and the next frame data as baseline data (baseline), judging whether the raw data is abnormal or not according to the difference between the raw data and the baseline, and determining that the raw data is abnormal if the difference between the raw data and the baseline is greater than a preset threshold value. And sequentially judging the detected touch data until the difference between the Nth touch data and the (N + 1) th touch data is not greater than a preset threshold value, and starting to judge the touch gesture from the Nth touch data.
And 303, controlling the terminal device to light up when the touch gesture corresponds to a preset screen lighting gesture.
And after the touch gesture is obtained, comparing the touch gesture with a preset screen-lighting gesture in the terminal equipment, and if the touch gesture corresponds to the preset screen-lighting gesture, controlling the terminal equipment to light the screen. Because the touch gesture is formed according to the touch data from the Nth touch data in the touch data queue, the touch gesture detection error caused by the large error of the touch data detected at the beginning is avoided, and the screen-lighting gesture of the user can be correctly responded.
According to the terminal screen-lighting control method provided by the embodiment of the application, when the terminal device is in a screen-lighting state, the touch data queue on the touch screen of the terminal device is detected, the touch gesture corresponding to the touch data queue is judged from the Nth touch data of the touch data queue, N is larger than or equal to 2, when the touch gesture corresponds to the preset screen-lighting gesture, the screen lighting of the terminal device is controlled, the touch gesture detection error caused by the fact that the touch data detected at the beginning has a large error is avoided, the screen-lighting gesture of a user can be correctly responded, and the use experience of the user is improved.
