技术领域technical field
本发明涉及触控显示技术领域，特别涉及一种桌面返回方法及系统。The present invention relates to the technical field of touch display, in particular to a method and system for returning a desktop.
背景技术Background technique
随着信息技术、无线移动通讯、信息家电及触控显示技术的快速发展与应用，为了达到携带更便利、体积更轻巧化以及操作更人性化的目的，触控显示设备孕育而生，触控显示设备(如大屏触控显示面板)是结合触控技术、显示技术及通信技术所形成的一种输入/输出装置，广泛运用在生活当中。With the rapid development and application of information technology, wireless mobile communication, information home appliances and touch display technology, in order to achieve the purpose of more convenient portability, lighter size and more humanized operation, touch display devices have been born. A display device (such as a large-screen touch display panel) is an input/output device formed by combining touch technology, display technology and communication technology, and is widely used in daily life.
众所周知的，在触控显示设备的使用当中，通常需要进行返回桌面的操作。As is well known, in the use of a touch display device, an operation of returning to the desktop is usually required.
现有技术当中，目前在进行返回桌面的操作时，常常需要找到并点击当前应用的【退出】按钮或者按下home物理按键(或者home虚拟按键)，才可以返回到触控显示设备的桌面。然而上述返回桌面的方案在具体使用过程当中，用户体验感差，容易导致操作不流畅，特别对于一些大屏触控显示面板，在大屏幕上寻找【退出】按钮或者按下下方的home物理按键(或者home虚拟按键)的过程均比较麻烦，同时长期通过home键来返回桌面也容易导致home键的损坏。In the prior art, when returning to the desktop, it is often necessary to find and click the [Exit] button of the current application or press the home physical button (or home virtual button) to return to the desktop of the touch display device. However, the above solution of returning to the desktop has a poor user experience during the specific use process, which may easily lead to unsmooth operation. Especially for some large-screen touch display panels, look for the [Exit] button on the large screen or press the home physical button below. (or the home virtual button) process is cumbersome, and returning to the desktop through the home button for a long time is also likely to cause damage to the home button.

The terms used herein in the description of the present invention are for the purpose of describing specific embodiments only, and are not intended to limit the present invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
请参阅图1，所示为本发明第一实施例中的桌面返回方法，应用于触控显示设备，包括步骤S01至步骤S03。Please refer to FIG. 1 , which shows a desktop return method in the first embodiment of the present invention, which is applied to a touch display device, including steps S01 to S03.
步骤S01，当检测到所述触控显示设备的触摸屏上存在多个触控感应点时，判断多个所述触控感应点是否集中成两个触控感应区。Step S01 , when it is detected that there are a plurality of touch sensing points on the touch screen of the touch display device, it is determined whether the plurality of touch sensing points are concentrated into two touch sensing areas.
可以理解的，根据触控原理可知，当触碰所述触摸屏时，所述触摸屏将在相应位置上感应到触碰，从而产生所述触控感应点，因此当检测到所述触摸屏上存在多个所触控感应点时，代表存在多个点(如用户的多个手指)正在触碰所述触摸屏。It can be understood that, according to the principle of touch control, when the touch screen is touched, the touch screen will sense a touch at a corresponding position, thereby generating the touch sensing point, so when it is detected that there are multiple When there are three touch sensing points, it means that there are multiple points (such as multiple fingers of the user) touching the touch screen.
需要指出的是，当两个所述触控感应点靠的近时，可以将这两个所述触控感应点化分在同一个感应区内，因此所述触控感应区内的所有所述触控感应点必然是相互之间靠得近的。如当用户用并拢的四个手指触碰所述触摸屏时，所述触摸屏将产生四个所述触控感应点，由于这四个所述触控感应点靠得近，此时四个所述触控感应点将集中在一个所述触控感应区内。It should be pointed out that when the two touch sensing points are close together, the two touch sensing points can be divided into the same sensing area, so all the touch sensing areas in the touch sensing area The touch sensing points must be close to each other. For example, when the user touches the touch screen with four fingers close together, the touch screen will generate four touch sensing points. Since the four touch sensing points are close, the four touch sensing points The touch sensing points will be concentrated in one of the touch sensing areas.
当所述步骤S01判断到多个所述触控感应点是集中成两个所述触控感应区时，则执行步骤S02，当所述步骤S01判断到多个所述触控感应点不是集中成两个所述触控感应区时，则不动作，继续检测。When the step S01 determines that the multiple touch sensing points are concentrated into two touch sensing areas, then execute step S02, and when the step S01 determines that the multiple touch sensing points are not concentrated When two touch sensing areas are formed, no action is taken and the detection is continued.
步骤S02，判断两个所述触控感应区内的所述触控感应点是否相向运动。Step S02 , judging whether the touch sensing points in the two touch sensing areas move toward each other.
其中，判断两个所述触控感应区内的所述触控感应点是否相向运动，是指判断所述触控感应区内的所述触控感应点相对另一个所述触控感应区内的所述触控感应点是否作相向运动。Wherein, judging whether the touch sensing points in the two touch sensing areas move toward each other refers to judging whether the touch sensing points in the touch sensing area are relative to the other touch sensing area. Whether the said touch sensing points move towards each other.
可以理解的，当触碰所述触摸屏的两个触碰点在所述触摸屏上做相向运动时，对应的两个触碰感应点也相应地进行相向运动。因此，当所述步骤S02判断出两个所述触控感应区内的所述触控感应点相向运动时，代表两个所述触控感应区上的触碰点(触碰所述触摸屏的点)在做相应地相向运动。例如，当用户用双手的并拢的四指触碰所述触摸屏，并在所述触摸屏上做相向运动时，所述触摸屏将产生八个所述触控感应点，并且将集中在两个所述触控感应区内，每个所述触控感应区内将包含四个所述触控感应点，同时当双手的并拢的四指在所述触摸屏上做相向运动时，两个所述触控感应区内的四个所述触控感应点将相应地做相向运动。It can be understood that when two touch points touching the touch screen move toward each other on the touch screen, the corresponding two touch sensing points also move toward each other correspondingly. Therefore, when it is determined in step S02 that the touch sensing points in the two touch sensing areas move toward each other, it means that the touch points on the two touch sensing areas (touching the touch screen) point) is doing corresponding relative motion. For example, when the user touches the touch screen with four fingers of both hands and moves towards each other on the touch screen, the touch screen will generate eight touch sensing points, and will focus on two of the touch sensing points. In the touch sensing area, each of the touch sensing areas will contain four of the touch sensing points. The four touch sensing points in the sensing area will move towards each other accordingly.
当所述步骤S02判断到两个所述触控感应区内的所述触控感应点相向运动时，则执行步骤S03，当所述步骤S02判断到两个所述触控感应区内的所述触控感应点没有相向运动时，则不动作，继续检测。When it is determined in step S02 that the touch sensing points in the two touch sensing areas are moving toward each other, then step S03 is executed. When the above-mentioned touch sensing points do not move toward each other, they do not act and continue to detect.
步骤S03，返回显示所述触控显示设备的桌面。Step S03, returning to displaying the desktop of the touch display device.
综上，本发明上述实施例当中的桌面返回方法，当用户想要回到所述触控显示设备的桌面时，可以通过将双手的并拢的手指(或单个手指)触碰到所述触控显示设备的触摸屏上，此时将检测到所述触摸屏上存在多个触控感应点，并且这些所述触控感应点必然集中成两个触控感应区，然后将双手的并拢的手指在所述触摸屏上相向滑动，根据触控原理，两个所述触控感应区内的所述触控感应点必然相向运动，此时即可返回显示所述触控显示设备的桌面。因此所述桌面返回方法及系统，由于在所述触摸屏上采用特定的手势即可完成返回桌面的操作，体验感好，提高了操作的流畅性。To sum up, in the method for returning to the desktop in the above-mentioned embodiments of the present invention, when the user wants to return to the desktop of the touch display device, he can touch the touch On the touch screen of the display device, it will be detected that there are multiple touch sensing points on the touch screen at this time, and these touch sensing points must be concentrated into two touch sensing areas, and then put the fingers of both hands together on the slide towards each other on the touch screen, according to the touch principle, the touch sensing points in the two touch sensing areas must move towards each other, and at this time, the desktop of the touch display device can be returned to display. Therefore, in the method and system for returning to the desktop, the operation of returning to the desktop can be completed by using a specific gesture on the touch screen, which has a good experience and improves the fluency of the operation.
请参阅图2，所示为本发明第二实施例中的桌面返回方法，包括步骤S11至步骤S19。Please refer to FIG. 2 , which shows the desktop returning method in the second embodiment of the present invention, including steps S11 to S19.

其中，所述触控感应区包括所述触控感应点及所述触控感应点周围一定范围内的区域。Wherein, the touch sensing area includes the touch sensing point and an area within a certain range around the touch sensing point.
可以理解的，所述将相邻之间距离小于第一预值的所有所述触控感应点组合成一个触控感应区的步骤是指，将靠得近的所有所述触控感应点组合成一个触控感应区。例如，当用户用并拢的四个手指触碰所述触摸屏时，所述触摸屏将产生四个所述触控感应点，同时四个所述触控感应点相邻之间的距离将小于所述第一预值，四个所述触控感应点将被组合成一个所述触控感应区。It can be understood that the step of combining all the touch-sensing points whose adjacent distances are smaller than the first preset value into one touch-sensing area refers to combining all the touch-sensing points that are close together into a touch sensitive area. For example, when the user touches the touch screen with four fingers close together, the touch screen will generate four touch sensing points, and the distance between adjacent four touch sensing points will be smaller than the For a first preset value, four touch sensing points will be combined into one touch sensing area.
步骤S12，判断多个所述触控感应点是否集中成两个所述触控感应区。Step S12 , judging whether a plurality of the touch sensing points are concentrated into two touch sensing areas.

当所述步骤S12判断到多个所述触控感应点是集中成两个所述触控感应区时，则执行步骤S13，当所述步骤S12判断到多个所述触控感应点不是集中成两个所述触控感应区时，则不动作，继续检测。When the step S12 judges that the plurality of touch sensing points are concentrated into two touch sensing areas, then execute step S13, and when the step S12 judges that the plurality of touch sensing points are not concentrated When two touch sensing areas are formed, no action is taken and the detection is continued.
步骤S13，判断两个所述触控感应区内的所述触控感应点的数量是否均为预设数目。Step S13 , judging whether the number of the touch sensing points in the two touch sensing areas is a preset number.
当所述步骤S13判断到两个所述触控感应区内的所述触控感应点的数量均为所述预设数目时，则执行步骤S14，当所述步骤S13判断到两个所述触控感应区内的所述触控感应点的数量不是均为所述预设数目时，则不动作，继续检测。When the step S13 judges that the number of the touch-sensing points in the two touch-sensing areas is the preset number, then execute the step S14, and when the step S13 judges that the two When the number of the touch sensing points in the touch sensing area is not all the preset number, no action is taken and the detection is continued.
换言之，当两个所述触控感应区内的所述触控感应点的数量不是均为所述预设数目(如4个)时，将不会进行返回显示所述触控显示设备的桌面的操作。In other words, when the number of the touch sensing points in the two touch sensing areas is not the preset number (such as 4), it will not return to display the desktop of the touch display device operation.
步骤S14，判断两个所述触控感应区之间的距离是否大于第二预值。Step S14, judging whether the distance between the two touch sensing areas is greater than a second preset value.
当步骤S14判断到两个所述触控感应区之间的距离大于第二预值时，则执行步骤S15，当步骤S14判断到两个所述触控感应区之间的距离不大于第二预值时，则不动作，继续检测。When step S14 determines that the distance between the two touch sensing areas is greater than the second preset value, step S15 is executed, and when step S14 determines that the distance between the two touch sensing areas is not greater than the second When the preset value is reached, no action will be taken and the detection will continue.
换言之，当两个所述触控感应之间的初始距离不大于所述第二预值时，将不会进行返回显示所述触控显示设备的桌面的操作。In other words, when the initial distance between the two touch sensors is not greater than the second preset value, the operation of returning to display the desktop of the touch display device will not be performed.
