背景技术Background technique

随着科学技术的发展，触摸屏在越来越多的电子设备上得到了广泛应用，用户可以通过触摸屏对设备进行各种各样的操作。With the development of science and technology, touch screens have been widely used in more and more electronic devices, and users can perform various operations on the devices through the touch screens.

现有的触摸屏大多为电容式触摸屏，电容式触控装置判断感应点是否被触控的方式为检测所述感应点的感应量，其中感应量为电容变化量，且能够以该感应点触控前后的电压变化量表示，当按压该电容式触摸屏时，在X轴和Y轴方向的扫描线上电后被触控到的点所在的X轴扫描线和Y轴扫描线就会各出现一个正的感应峰值，而出现感应峰值的地方就是被按压到的位置。在触摸屏系统中，在得到一帧时间内的感应(Diff)数据后需要快速获取按压的峰值区域，从而定位触控区域。Most of the existing touch screens are capacitive touch screens, and the capacitive touch device determines whether the sensing point is touched by detecting the sensing quantity of the sensing point, wherein the sensing quantity is the capacitance change, and the sensing point can be used to touch the sensing point. The amount of voltage change before and after indicates that when the capacitive touch screen is pressed, the X-axis scan line and the Y-axis scan line where the touched point is located after the scan lines in the X-axis and Y-axis directions are powered up will appear one each. Positive induction peak, and the place where the induction peak occurs is the position that is pressed. In a touch screen system, after obtaining the sensing (Diff) data within a frame time, it is necessary to quickly obtain the peak area of pressing, so as to locate the touch area.

现有技术中，确定按压的峰值区域需要通过触控装置对触摸屏上的所有感应点(sensor)按行和列逐个搜索并查找满足感应大于预定阈值并且大于相邻感应点的位置，耗费时间较长，搜索的特征较为单一，轮廓信息不好获取，数字电路硬件化困难。In the prior art, to determine the peak area of the pressing, it is necessary to search all the sensing points (sensors) on the touch screen row and column one by one through the touch device and find the position that satisfies the sensing greater than the predetermined threshold and greater than the adjacent sensing points, which takes a relatively long time. It is long, the features of the search are relatively single, the contour information is not easy to obtain, and the hardware of the digital circuit is difficult.

进一步的，步骤S3：分别获取第一方向投影区20和所述第二方向投影区30的投影峰值点的步骤包括：Further, step S3: the step of respectively acquiring the projection peak points of the first-direction projection area 20 and the second-direction projection area 30 includes:

分别遍历第一方向投影区20和第二方向投影区30，将感应数据大于设定阈值(本实施例的设定阈值以150为例)，且大于与其相邻的感应数据的投影点确定为投影峰值点。图3-图6中虚线椭圆圈起来的数据所在的点即为第一方向投影区20和第二方向投影区30上的投影峰值点，投影峰值点的获取可以通过ALU算法。Traverse the first-direction projection area 20 and the second-direction projection area 30 respectively, and determine the projection point where the sensing data is greater than the set threshold (the set threshold in this embodiment is 150 as an example), and is greater than the projection point of the adjacent sensing data as Projected peak point. The points where the data circled by the dotted ellipse in FIGS. 3 to 6 are located are the projection peak points on the first-direction projection area 20 and the second-direction projection area 30, and the projection peak point can be obtained through the ALU algorithm.

进一步的，步骤S4：根据第一方向投影区20和第二方向投影区30的投影峰值点以及感应数据组的对应关系确定实际的峰值感应点的步骤包括：在感应数据组中分别将第一方向投影区20的至少一个第一峰值感应点对应的一行感应数据确定为第一备选通道；在感应数据组中分别将第二方向投影区30的至少一个第二峰值感应点对应的一列感应数据确定为第二备选通道；获得感应数据组中第一备选通道和第二备选通道交点位置上的至少一个感应点；以及将交点位置上的至少一个感应点中的感应数据大于设定阈值的感应点确定为实际的峰值感应点。Further, step S4: the step of determining the actual peak sensing point according to the projection peak points of the projection area 20 in the first direction and the projection area 30 in the second direction and the corresponding relationship of the sensing data set includes: in the sensing data set, the first A row of sensing data corresponding to at least one first peak sensing point in the direction projection area 20 is determined as the first candidate channel; in the sensing data group, a column corresponding to at least one second peak sensing point in the second direction projection area 30 is respectively sensed The data is determined as the second candidate channel; at least one sensing point at the intersection of the first candidate channel and the second candidate channel in the sensing data group is obtained; and the sensing data in the at least one sensing point at the intersection position is greater than the set value. The threshold sensing point is determined as the actual peak sensing point.

参照图5，第一方向投影区20的第一峰值感应点上的感应数据737、767、800、879、807所在的行为第一备选通道，第二方向投影区30的第二峰值感应点上的感应数据807、767、879、800所在的列作为第二备选通道，感应数据737所在的第一备选通道与第二备选通道相交得到了交点R(1,1)、G(1,2)、G(1,3)、G(1,4)，之后判断交点R(1,1)、G(1,2)、G(1,3)、G(1,1)和预定阈值的大小关系，判断方式不限，可以通过软件程序或者ALU算法，通过判断只有交点R(1,1)上的感应数据大于预定阈值，那么交点R(1,1)就是实际的峰值感应点，而交点G(1,2)、G(1,3)、G(1,1)上的感应数据小于预定阈值，那么G(1,2)、G(1,3)、G(1,4)即为本领域所述的鬼点，需要滤除。图5为了显示清晰，仅示出部分交点，实际判断过程中，需要获取所有第一备选通道与第二备选通道的交点，再将所有交点上的感应数据与预定阈值进行比较，然后滤除小于预定阈值的感应数据所在的点。Referring to FIG. 5 , the sensing data 737 , 767 , 800 , 879 , and 807 on the first peak sensing point of the first direction projection area 20 are located in the first candidate channel, and the second peak sensing point of the second direction projection area 30 is located. The column where the sensing data 807, 767, 879, and 800 are located on is used as the second candidate channel, and the first candidate channel where the sensing data 737 is located intersects with the second candidate channel to obtain the intersection points R(1,1), G( 1,2), G(1,3), G(1,4), and then determine the intersection points R(1,1), G(1,2), G(1,3), G(1,1) and The relationship between the predetermined threshold value and the judgment method is not limited. It can be determined by software program or ALU algorithm. By judging that only the sensing data at the intersection point R(1,1) is greater than the predetermined threshold value, then the intersection point R(1,1) is the actual peak sensing point, and the sensing data at the intersection points G(1,2), G(1,3), G(1,1) are less than the predetermined threshold, then G(1,2), G(1,3), G(1 , 4) is the ghost point described in the field and needs to be filtered out. Figure 5 only shows some intersection points for the sake of clarity. In the actual judgment process, it is necessary to obtain the intersection points of all the first candidate channels and the second candidate channels, and then compare the sensing data on all the intersection points with the predetermined threshold, and then filter Divide the points where the sensed data is less than a predetermined threshold.

本发明实施例提供的触控定位方法，在获取到一帧时间内的感应数据后，将二维的感应数据投影成一维的投影数据，确定投影峰值点后再根据第一方向投影区20和第二方向投影区30与感应数据组的投影对应关系确定实际的峰值感应点，扫描时间短，可以快速定位触控区域。In the touch positioning method provided by the embodiment of the present invention, after acquiring the sensing data within a frame time, the two-dimensional sensing data is projected into one-dimensional projection data, the projection peak point is determined, and then the projection area 20 and The projection correspondence between the projection area 30 in the second direction and the sensing data set determines the actual peak sensing point. The scanning time is short, and the touch area can be quickly located.

本发明提供的触控定位方法，还可以根据第一方向投影区20和第二方向投影区30的投影峰值点确定各个峰值感应点所处位置的峰值感应区域。The touch positioning method provided by the present invention can also determine the peak sensing area where each peak sensing point is located according to the projection peak points of the projection area 20 in the first direction and the projection area 30 in the second direction.

进一步的，根据第一方向投影区20和第二方向投影区30的投影峰值点确定各个峰值感应点所处位置的峰值感应区域的步骤包括：分别获取各个峰值感应点在第一方向投影区20的投影峰值点前后大于设定阈值的感应点的个数作为行宽；分别获取各个峰值感应点在所述第二方向投影区的投影峰值点前后大于设定阈值的感应点的个数作为列宽；以各个峰值感应点为中心，并根据各个峰值感应点的行宽和列宽在感应量数据组中对应的感应数据确定第一峰值区域；以及对第一峰值区域边缘优化确定所述各个峰值感应点所处位置的峰值感应区域。其中，投影峰值点及其前后大于设定阈值的感应点所在的区域为投影峰值区域。Further, the step of determining the peak sensing area where each peak sensing point is located according to the projection peak points of the first direction projection area 20 and the second direction projection area 30 includes: respectively acquiring each peak sensing point in the first direction projection area 20. The number of sensing points that are greater than the set threshold before and after the projection peak point is taken as the row width; the number of sensing points that are greater than the set threshold before and after the projection peak point of each peak sensing point in the projection area of the second direction is obtained as the column. taking each peak sensing point as the center, and determining the first peak area according to the corresponding sensing data of the row width and column width of each peak sensing point in the sensing quantity data set; and optimizing the edge of the first peak area to determine the each peak area The peak sensing area where the peak sensing point is located. Among them, the projection peak point and the area where the sensing points before and after it are greater than the set threshold are located are the projection peak area.

参照图5，以实际的峰值感应点上的感应数据807为例，它在第一方向投影区20的投影峰值区域为YP5，投影峰值807前面有一个大于预定阈值的数据379，后面有一个大于预定阈值的数据499，它在第二方向投影区的投影峰值807的投影区域为XP1,它前面有两个大于预定阈值的数据169、567，它后面有两个大于预定阈值的数据790、346，由此可以确定该峰值感应点的行宽为前1后1，列宽为前2后2。YP1-YP4为第一投影区20的投影峰值区域，XP2-XP4为第二投影区30的投影峰值区域，不过如果该投影峰值前后的感应数据为其他的投影峰值，则自动截止不再计算。之后以感应数据807所在的实际峰值感应点为中心，根据该峰值感应点的行宽和列宽在感应数据组中对应的感应数据即可确定感应数据807所在的峰值感应点的第一峰值区域，具体对应关系是以感应数据807为中心，将感应数据807所在行及其前面一行和后面一行与感应数据807所在列及其前面两列和后面两列的重叠区域确定为该峰值感应点的第一峰值区域，即图6中的GP5。同理可以确定其他峰值感应点的第一峰值区域GP1-GP4，从图中可以看出因为感应数据组中同一列或者同一行上可能有两个以上的峰值点，投影时出现影子覆盖，使得其行宽或者列宽出现偏差，所以得到的第一峰值区域会出现不准确的情况，所以需要对其边缘进行优化以得到实际的峰值感应区域。Referring to FIG. 5, taking the sensing data 807 on the actual peak sensing point as an example, the projection peak area of the projection area 20 in the first direction is YP5, the projection peak 807 has a data 379 larger than a predetermined threshold in front, and a data 379 larger than a predetermined threshold in the back. The data 499 of the predetermined threshold, the projection area of the projection peak 807 of the projection area in the second direction is XP1, there are two data 169, 567 greater than the predetermined threshold in front of it, and there are two data 790, 346 behind it that are greater than the predetermined threshold , it can be determined that the row width of the peak sensing point is the first 1 and the last 1, and the column width is the first 2 and the last 2. YP1-YP4 are the projection peak areas of the first projection area 20, and XP2-XP4 are the projection peak areas of the second projection area 30. However, if the sensing data before and after the projection peak are other projection peaks, the automatic cutoff will not be calculated. Then, taking the actual peak sensing point where the sensing data 807 is located as the center, and according to the sensing data corresponding to the row width and column width of the peak sensing point in the sensing data group, the first peak area of the peak sensing point where the sensing data 807 is located can be determined. , the specific correspondence is centered on the sensing data 807, and the overlapping area of the row where the sensing data 807 is located, its previous row and the following row and the column where the sensing data 807 is located, and the first two columns and the latter two columns is determined as the peak sensing point. The first peak region, namely GP5 in Figure 6. Similarly, the first peak areas GP1-GP4 of other peak sensing points can be determined. It can be seen from the figure that because there may be more than two peak points in the same column or row in the sensing data set, shadow coverage occurs during projection, so that The row width or column width deviates, so the obtained first peak area may be inaccurate, so the edge needs to be optimized to obtain the actual peak sensing area.

进一步的，对第一峰值区域边缘优化确定各个峰值感应点所处位置的峰值感应区域的步骤包括：将第一峰值区域上的一个边界的感应数据与设定阈值进行比较，若边界上的感应数据均小于设定阈值，则将边界沿靠近峰值感应点的方向移动，直到该边界中出现至少一个感应数据大于设定阈值，则该感应数据所在的位置的边界即为该方向的边界；重复上述的比较，直至所述第一峰值区域的四个边界均被调整；以及将调整之后的四个边界确定的区域设置为最终的所述峰值感应区域。将所述第一峰值区域上的一个边界的感应数据与设定够阈值进行比较，若边界上的感应数据均大于设定阈值，则将边界沿背离所述峰值感应点的方向移动，直到边界中出现至少一个感应数据小于设定阈值，则该感应数据的所在位置的前一位置的边界的即为该方向的边界；重复上述的比较，直至第一峰值区域的四个边界均被调整；以及将调整之后的四个边界确定的区域设置为最终的峰值感应区域。Further, the step of determining the peak sensing area where each peak sensing point is located by optimizing the edge of the first peak area includes: comparing the sensing data of a boundary on the first peak area with a set threshold, if the sensing data on the boundary is If the data are all less than the set threshold, move the boundary in the direction close to the peak sensing point until at least one sensing data in the boundary is greater than the set threshold, then the boundary of the location where the sensing data is located is the boundary of the direction; repeat In the above comparison, all four boundaries of the first peak region are adjusted; and the region determined by the four boundaries after the adjustment is set as the final peak sensing region. Compare the sensing data of a boundary on the first peak area with the set threshold, and if the sensing data on the boundary are all greater than the set threshold, move the boundary in a direction away from the peak sensing point until the boundary If at least one sensing data is less than the set threshold, the boundary of the previous position of the sensing data is the boundary of the direction; the above-mentioned comparison is repeated until the four boundaries of the first peak area are adjusted; And the area determined by the four boundaries after adjustment is set as the final peak sensing area.

参照图6，第一峰值区域GP1、GP5、GP3都需要对边缘进行优化，其中GP1、GP5存在箭头的边界需要向靠近峰值感应点的方向，即向箭头指向的方向搜索，直到该边界中出现至少一个感应数据大于设定阈值，将其所在位置的边界确定为GP1、GP5真正的边界；GP3存在箭头的边界需要向背离峰值感应点的方向的移动，即箭头指向的方向，直到该边界中出现至少一个感应数据小于设定阈值，将其所在位置的前一位置的边界确定为GP3真正的边界。Referring to FIG. 6 , the edges of the first peak regions GP1, GP5, and GP3 need to be optimized, and the boundaries of GP1 and GP5 with arrows need to be searched in the direction close to the peak sensing point, that is, in the direction pointed by the arrows, until the boundary appears. At least one sensing data is greater than the set threshold, and the boundary of its location is determined as the real boundary of GP1 and GP5; the boundary of GP3 with arrows needs to move in the direction away from the peak sensing point, that is, the direction pointed by the arrow, until the boundary When at least one sensing data is smaller than the set threshold, the boundary of the previous position of its position is determined as the real boundary of GP3.

应当说明，本领域普通技术人员可以理解，本文中使用的与电路运行相关的词语“期间”、“当”和“当……时”不是表示在启动动作开始时立即发生的动作的严格术语，而是在其与启动动作所发起的反应动作(reaction)之间可能存在一些小的但是合理的一个或多个延迟，例如各种传输延迟等。本文中使用词语“大约”或者“基本上”意指要素值(element)具有预期接近所声明的值或位置的参数。然而，如本领域所周知的，总是存在微小的偏差使得该值或位置难以严格为所声明的值。本领域已恰当的确定了，至少百分之十(10％)(对于半导体掺杂浓度，至少百分之二十(20％))的偏差是偏离所描述的准确的理想目标的合理偏差。当结合信号状态使用时，信号的实际电压值或逻辑状态(例如“1”或“0”)取决于使用正逻辑还是负逻辑。It should be noted that those of ordinary skill in the art will understand that the terms "during", "while" and "when" used herein in relation to the operation of a circuit are not strict terms denoting actions that occur immediately upon initiation of the action, Rather, there may be some small but reasonable delay or delays between it and the reaction initiated by the initiating action, such as various transmission delays, etc. The words "about" or "substantially" are used herein to mean that an element has a parameter that is expected to be close to the stated value or position. However, as is well known in the art, there are always slight deviations that make it difficult for the value or location to be exactly the stated value. It is well established in the art that a deviation of at least ten percent (10%) (for semiconductor doping concentration, at least twenty percent (20%)) is a reasonable deviation from the exact ideal described. When used in conjunction with signal states, the actual voltage value or logic state of the signal (eg, "1" or "0") depends on whether positive or negative logic is used.

本文中描述的方法中的多个步骤，除非特意指出，仅仅作为示例而非意指严格限制步骤的先后顺序，本领域的技术人员可以根据实际工艺条件改变多个步骤的先后顺序。本文中描述的产品中的部件的数，除非特意指出，仅仅作为示例而非意指严格限定该数的数值，本领域的技术人员可以根据实际产品要求改变数的数值。The multiple steps in the method described herein, unless otherwise specified, are only used as examples and are not meant to strictly limit the sequence of the steps, and those skilled in the art can change the sequence of the multiple steps according to actual process conditions. The number of components in the product described herein, unless otherwise specified, is merely an example and is not intended to strictly limit the numerical value of the number, and those skilled in the art can change the numerical value of the number according to actual product requirements.
