针对杂讯干扰电容量一事,触控面板的控制器已设定不同杂讯类型的标志(Flag),供该控制器执行报点程序时,可排除杂讯干扰,以液体所造成的杂讯干扰来说,目前触控面板的控制器设定有液体标志,一旦从触控信号判断出有液体存在于触控面板上,即将该液体标志予以标记,于该控制器执行后续报点程序时,会判断液体标志已被标记,而排除液体干扰,例如原本为多指报点程序,即限制为单点报点程序,减少因杂讯干扰而误判多物体的现象。Regarding the issue of noise interfering with capacitance, the controller of the touch panel has set flags (Flag) of different noise types for the controller to eliminate noise interference when the controller executes the report program, and the noise caused by liquid In terms of interference, the current touch panel controller is set with a liquid flag. Once it is judged from the touch signal that there is liquid on the touch panel, the liquid flag will be marked. When the controller executes the follow-up reporting program , it will judge that the liquid mark has been marked, and eliminate the liquid interference. For example, the original multi-finger reporting program is limited to a single-point reporting program to reduce the misjudgment of multiple objects due to noise interference.

具体实施方式Detailed ways
为提升一触控面板上识别液体存在的正确性,请参阅图1及图2,本发明包括有以下主要步骤:In order to improve the accuracy of identifying the presence of liquid on a touch panel, please refer to Figure 1 and Figure 2, the present invention includes the following main steps:
判断触控面板10上无触碰物体(S10);Judging that there is no touching object on the touch panel 10 (S10);
读取至少一全点式感应图框(S11),以互容扫描方式扫描该触控面板10,获得该全点式感应图框;Read at least one full-point sensing frame (S11), and scan the touch panel 10 in a mutual capacitance scanning manner to obtain the full-point sensing frame;
计算有效感应点数量(S12),在各全点式感应图框中,将感应点的感应值超过一液体感应值的该感应点视为有效感应点,并计算有效感应点数量;及Calculate the number of effective sensing points (S12). In each full-point sensing map frame, consider the sensing point whose sensing value exceeds a liquid sensing value as an effective sensing point, and calculate the number of effective sensing points; and
识别液体物体(S13),判断该有效感应点数量超过一预设临界值时,则识别该液体物体存在(S14)。Identifying the liquid object (S13), and identifying the presence of the liquid object when it is judged that the number of effective sensing points exceeds a preset threshold (S14).
当识别有液体物体存在,则该触控面板10的控制器11会将触碰信号的液体标志予以标记,令操作系统12接收到此一触碰信号后,由已标记的液体标志获知目前触控面板10上有液体存在,以在后续执行排除触控面板10上液体存在的干扰作业,例如不处理或忽略该触控信号的坐标。When it is recognized that there is a liquid object, the controller 11 of the touch panel 10 will mark the liquid symbol of the touch signal, so that the operating system 12 can know the current touch signal from the marked liquid symbol after receiving the touch signal. There is liquid on the touch panel 10, so as to eliminate the interference operation of the liquid on the touch panel 10, for example, not processing or ignoring the coordinates of the touch signal.
再请配合参阅图3所示,本发明实现以上主要步骤的第一较佳实施例的流程图,其中实现上述判断触控面板上无触碰物体步骤的实际作法包括有:Please refer to FIG. 3 again, the flow chart of the first preferred embodiment of the present invention to realize the above main steps, wherein the actual practice of realizing the above step of judging that there is no touch object on the touch panel includes:
以自容式扫描该触控面板,以获得该触控面板的各条感应线的感应量(S101);Scanning the touch panel in a self-capacitive manner to obtain sensing values of each sensing line of the touch panel (S101);
判断各感应线的感应量是否超过一预设自容触碰感应量;若无,则目前触控板上未有触碰物体(S102)。It is judged whether the sensing amount of each sensing line exceeds a preset self-capacitance touch sensing amount; if not, there is no touch object on the touch panel (S102).
请配合参阅图1及4所示,为自容式及互容式分别扫描包括有液体的触控面板10,由自容式扫描后各条行、列感应数量均为0(如灰阶标示)可知,自容式扫描各条感应线101、102的感应量并不受液体的干扰,其中一种自容式扫描方法是以同相驱动信号同时输出至行感应线,同时对各条行、列感应线101、102输出激励信号,接着依序接收各感应线101、102的感应量,直到所有感应线101、102均取得感应量,即可输出一组感应信息。由于如水滴等液体出现在触控面板上,且水滴位置对应其中数条相邻感应线,则虽然各条感应线的电压会因为水滴而有上升或下降变化,但同时对所有感应线输出相同相位的激励信号,即可使得相邻感应线之间的电位相同或相近,使得依序接收对应水滴位置的各条感应线的感应量,该感应量中不会包括有水滴感应量的变化;因此,单端输入同相扫描方式输出的感应信息即能有效排除水滴等液体的干扰;反之,由互容式扫描而得的全点式感应图框(如不以灰阶标示),对应液体位置的感应点即出现非0的正感应量;是以,本实施例以自容式扫描该触控面板10,可判断该触控面板10上是否存在触控物体,若确定无触碰物体才执行图1其余步骤(S11~S14)。Please refer to Figures 1 and 4, which are self-capacitance and mutual-capacity scanning of the touch panel 10 containing liquid respectively. After self-capacity scanning, the sensing numbers of each row and column are all 0 (as indicated by the gray scale. ), it can be seen that the sensing values of the sensing lines 101 and 102 in the self-capacity scanning are not disturbed by the liquid. One of the self-capacitance scanning methods is to simultaneously output the in-phase drive signal to the row sensing lines, and at the same time, each row, The column sensing lines 101, 102 output excitation signals, and then receive the sensing values of each sensing line 101, 102 in sequence, until all the sensing lines 101, 102 have obtained sensing values, a set of sensing information can be output. Since liquid such as water drops appears on the touch panel, and the position of the water drop corresponds to several adjacent sensing lines, although the voltage of each sensing line will rise or fall due to the water drop, the output is the same for all sensing lines at the same time. The excitation signal of the phase can make the potentials between adjacent sensing lines the same or similar, so that the sensing amount of each sensing line corresponding to the position of the water drop is sequentially received, and the sensing amount does not include the change of the sensing amount of the water drop; Therefore, the sensing information output by single-ended input and in-phase scanning can effectively eliminate the interference of liquids such as water droplets; on the contrary, the full-point sensing frame (if not marked in gray scale) obtained by mutual capacitance scanning corresponds to the position of the liquid A non-zero positive sensing value appears at the sensing point; therefore, this embodiment scans the touch panel 10 in a self-capacitance manner to determine whether there is a touch object on the touch panel 10. If it is determined that there is no touch object, then Execute the remaining steps (S11-S14) in Fig. 1 .
此外,再请参阅图5所示,为本发明第二较佳实施例的流程图,是揭示实现上述判断触控面板10上无触碰物体步骤的另一实际作法,其包括有:In addition, please refer to FIG. 5 again, which is a flow chart of the second preferred embodiment of the present invention, which discloses another practical method for realizing the above-mentioned step of judging that there is no object touched on the touch panel 10, which includes:
以互容式扫描该触控面板10,以获得一感应图框(S103);scanning the touch panel 10 in a mutual capacitive manner to obtain a sensing frame (S103);
判断该感应图框上是否有感应量超过一预设互容触碰感应量的感应点(S104);若无,则识别该触控板上未有触碰物体;Judging whether there is a sensing point on the sensing frame whose sensing value exceeds a preset mutual capacity touch sensing value (S104); if not, then identifying that there is no touching object on the touch panel;
若有,则判断该多个感应点构成的感应群形状是否符合触碰物体感应群形状(S105),若不相符,则识别该触控板上没有触碰物体。If so, it is judged whether the shape of the sensing group formed by the plurality of sensing points conforms to the shape of the sensing group of the touch object (S105), and if not, it is recognized that there is no touch object on the touch panel.
上述实施例是以互容式扫描该触控面板10进行有无触碰物体的判断,由于一触碰物体会对应一具有多个感应点的感应群,故可通过判断感应群形状加以识别是否有触控物体;如图6所示,以全点式扫描包括有不同位置的液体物体及触碰物体的触控面板10所获得的全点式感应图框,虽然液体物体也出现具有多个感应点的感应群20,但其感应点的感应量分布情形与触碰物体的感应群30中感应点的感应量分布情形并不相同,最大不同之处在于液体物体的感应群20中间感应量较其周边感应点的感应量为低,甚至为0或负值,而触碰物体的感应群30则是中间感应量较其周边为高,甚至最高;是以,藉此方式同样可先识别该触控面板上是否有存在触碰物体,一旦确认无触碰物体,开始执行图1的其余步骤(S11~S14)。In the above-mentioned embodiment, the touch panel 10 is scanned in mutual capacity to judge whether there is a touch object. Since a touch object corresponds to a sensing group with multiple sensing points, it can be identified by judging the shape of the sensing group. There is a touch object; as shown in Figure 6, the full-point sensing frame obtained by scanning the touch panel 10 that includes liquid objects in different positions and the touch objects is used as shown in Figure 6, although the liquid object also appears to have multiple The sensing group 20 of the sensing point, but the distribution of the sensing amount of the sensing point is different from the distribution of the sensing amount of the sensing point in the sensing group 30 of the touching object. The biggest difference lies in the middle sensing amount of the sensing group 20 of the liquid object. The sensing value of the surrounding sensing points is lower, or even 0 or negative, while the sensing value of the sensing group 30 touching the object is higher, or even the highest, than the surrounding sensing points; Whether there is a touch object on the touch panel, once it is confirmed that there is no touch object, start to execute the remaining steps (S11-S14) in FIG. 1 .
再者,为排除本发明将其它杂讯(如充电杂讯或LCM杂讯等)误判为液体物体,则可进一步设定一预设张数,并读取该预设张数的全点式感应图框,当判断所有全点式感应图框的有效感应点数量均超过预设临界值后,才识别液体物体存在。实际实现的流程图如图7所示,其包括有:Furthermore, in order to exclude other noises (such as charging noise or LCM noise, etc.) misjudged as liquid objects by the present invention, a preset number of sheets can be further set, and the full points of the preset number of sheets can be read. When it is judged that the number of effective sensing points of all the full-point sensing frames exceeds the preset critical value, the existence of the liquid object is recognized. The actual implementation flow chart is shown in Figure 7, which includes:
(a)判断触控面板10上无触碰物体(S10’);(a) judging that there is no touch object on the touch panel 10 (S10');
(b)读取一全点式感应图框(S11),以互容扫描方式扫描该触控面板,获得该全点式感应图框;(b) Read a full-point sensing frame (S11), scan the touch panel in a mutual-capacity scanning manner, and obtain the full-point sensing frame;
(c)计算有效感应点数量(S12),在各全点式感应图框中,将感应点的感应值超过一液体感应值的该感应点视为有效感应点,并计算有效感应点数量;(c) Calculate the number of effective sensing points (S12). In each full-point sensing map frame, consider the sensing point whose sensing value exceeds a liquid sensing value as an effective sensing point, and calculate the number of effective sensing points;
(d)判断该有效感应点数量是否超过一预设临界值(S13),若否则返回步骤(a);若是,则进一步判断是否到达预设张数(S131),若尚未达到预设张数,返回步骤(a);若已到达该预设张数,则执行下一步骤;及(d) Judging whether the number of effective sensing points exceeds a preset critical value (S13), if not, return to step (a); if so, then further judge whether the preset number has been reached (S131), if not yet reached the preset number , return to step (a); if the preset number of sheets has been reached, proceed to the next step; and
(e)识别该液体物体存在(S14)。(e) Recognize that the liquid object exists (S14).
由上述步骤(a)至(e)可知,当连续预设张数的全点式感应图框的各张全点式感应图框的有效感应点数量,均超过一预设感应临界值时,则识别为液体物体存在,并借此排除出现时间较短的杂讯(如充电杂讯);当然上述步骤(a)判断无触碰物体的判断方式同样可采用第一或第二较佳实施例的作法。From the above steps (a) to (e), it can be seen that when the number of effective sensing points of each full-point sensing frame of the continuous predetermined number of full-point sensing frames exceeds a preset sensing threshold, Then it is recognized that there is a liquid object, and the noise (such as charging noise) that appears for a short time is eliminated; of course, the judgment method of the above step (a) to judge that there is no touching object can also adopt the first or second preferred implementation Example approach.
综上所述,本发明主要以易受液体干扰而产生电容变化量的全点式感应图框进行液体有无的识别,并在确定无触碰物体后开始读取该全点式感应图框,并预设一液体感应值,若全点式感应图框的感应点的感应值有超过该液体感应值,且感应值超过液体感应值的感应点数量高过预设临界值,即确认有液体物体存在;如此,即可将该液体标志予以标记,以利后续执行排除触控面板上液体存在的干扰作业。To sum up, the present invention mainly uses the full-point sensing frame that is susceptible to liquid interference to produce capacitance changes to identify the presence or absence of liquid, and starts to read the full-point sensing frame after it is determined that there is no touching object , and preset a liquid sensing value, if the sensing value of the sensing point of the full-point sensing frame exceeds the liquid sensing value, and the number of sensing points whose sensing value exceeds the liquid sensing value is higher than the preset critical value, it is confirmed that there is There is a liquid object; in this way, the liquid mark can be marked, so as to facilitate the subsequent execution of the interference operation of eliminating the presence of liquid on the touch panel.
