Example one
Referring to fig. 1, the present embodiment provides a screen display method, including:
step S101: receiving a detection instruction for the touch screen, and detecting all touch induction channels of the touch screen according to the detection instruction so as to detect abnormal touch induction channels and positions thereof; and all the abnormal touch sensing channels divide the touch screen into a plurality of display windows.
For example, the detection instruction may be issued by a user through a setting button in a setting menu in the terminal device, the setting button is in an off state in a normal state, and when the user feels that the touch performance of the touch screen is not good, the terminal device starts to detect all touch sensing channels of the touch screen by opening the setting button to issue the detection instruction.
According to the detection instruction, all touch induction channels of the touch screen are detected to detect abnormal touch induction channels, and the method comprises the following steps:
(a) detecting all touch induction channels of the touch screen according to the detection instruction to obtain performance parameters respectively corresponding to all the touch induction channels;
(b) determining whether each touch sensing channel is an abnormal touch sensing channel or not according to a comparison result of the performance parameter corresponding to each touch sensing channel and a preset parameter, and determining the position of each abnormal touch sensing channel;
when the performance parameters corresponding to the current touch sensing channel are inconsistent with the preset parameters, the current touch sensing channel is an abnormal touch sensing channel;
and when the performance parameter corresponding to the current touch sensing channel is consistent with the preset parameter, the current touch sensing channel is a normal touch sensing channel.
The performance parameters include capacitance value and noise. The location of the abnormal touch-sensitive channel includes coordinates of the abnormal touch-sensitive channel. And comparing the performance parameters of each touch induction channel with preset parameters, if abnormity occurs or the comparison fails, indicating that the current touch screen is abnormal and damaged, retrieving the coordinates (including x-axis coordinates and y-axis coordinates) of the abnormal touch induction channel, and if the multiple channels are damaged, retrieving and storing the coordinates respectively.
For example, the possible distribution situations of the abnormal touch sensing channels are shown in fig. 2 to 4, and all the abnormal touch sensing channels divide the touch screen into several display windows, such as 4 display windows in fig. 2, 6 display windows in fig. 3, and 9 display windows in fig. 4.
Step S102: and calculating the display areas of all the display windows according to the positions of all the abnormal touch sensing channels, and selecting the display window with the largest display area as a target display window.
Specifically, the display areas of all the display windows are calculated according to the coordinates of all the abnormal touch sensing channels, and the display window with the largest display area is selected as the target display window.
As shown in fig. 2, the display area of the display window located at the lower right corner of the touch screen is the largest, which is the target display window; as shown in fig. 3, the display area of the display window located at the lower right corner of the touch screen is the largest, which is the target display window; as shown in fig. 4, the display window located in the middle of the touch screen has the largest display area, i.e., the target display window.
Step S103: and receiving touch operation, and displaying all display contents of the touch screen in the target display window according to the touch operation.
Specifically, once a touch operation of a user on the display screen is received, all display contents of the touch screen are displayed in the target display window. Therefore, the user can perform normal touch operation in the target display window, and avoids an abnormal touch induction channel, so that the touch operation is not influenced, the inconvenience caused by the fact that the touch screen is partially damaged and cannot be touched is solved, the cost is reduced, and the method is more humanized.
Displaying all display contents of the touch screen in the target display window according to the touch operation, and the method comprises the following steps:
(a) calculating the resolution of the target display window according to the positions of all the abnormal touch sensing channels and the size and resolution of the touch screen;
(b) and displaying all display contents of the touch screen in the target display window according to the touch operation and the resolution of the target display window.
For example, the origin of the entire coordinate system may be located at the upper left corner of the touch screen, and the coordinates of the abnormal touch sensing channel may be determined based on the number of pixels, that is, the unit of the coordinates of the abnormal touch sensing channel may be the number of pixels, and the abscissa difference and the ordinate difference are calculated directly according to the coordinates of the four vertices of the target display window, where the abscissa difference × the ordinate difference is the resolution of the target display window.
And displaying all display contents of the touch screen in the target display window according to the touch operation and the resolution of the target display window, namely using the target display window as a new operation screen, so that the touch operation of a user is facilitated, and the operability and convenience of the user are greatly improved.
Step S104: and when the touch operation is not received within a preset time length, restoring all display contents of the touch screen to full-screen display.
Specifically, when the touch operation is not received within the preset time, it is indicated that the user does not need to perform the touch operation temporarily, full-screen display is resumed at this time, and all display contents of the touch screen are displayed in the target display window according to the touch operation until the touch operation is received again, so that the operability and convenience of the user are greatly improved.
Step S105: and receiving a full-screen display instruction, and restoring all display contents of the touch screen to full-screen display according to the full-screen display instruction.
Illustratively, when a user is watching a video and the like, the video can be watched more conveniently through full-screen display, the user can restore full-screen display through a full-screen display key in the target display window, and the perception and comfort of the user are greatly improved. And when the touch operation is received again, displaying all display contents of the touch screen in the target display window according to the touch operation, so that the operability and convenience of a user are greatly improved.
