The above touch manners in the non-bending direction are only for illustration and not for limitation.
在实际操作时，由于采用采用投射电容式自容式触控技术和电阻触控技术仅需要设置一个方向上(即弯曲方向上)的触控驱动/感应线，因此本发明实施例所述的触控装置在弯曲方向上优选采用投射电容式自容式触控方式和电阻触控方式，以上在弯曲方向上的优选的触控方式仅作为举例说明，并不作限制。In actual operation, since the projected capacitive self-capacitive touch technology and the resistive touch technology only need to set the touch driving/sensing lines in one direction (that is, in the bending direction), the embodiment of the present invention The touch device preferably adopts the projected capacitive self-capacitance touch method and the resistive touch method in the bending direction, and the above preferred touch methods in the bending direction are only for illustration and not for limitation.

也即在一具体实施例中，所述红外线发射器和所述红外线接收器是分边设置的，并且所述红外线发射器和所述红外线接收器是一一对应的；所述处理单元13通过判断所红外线接收器接收到的红外线是否被遮挡而判断在非弯曲方向上是否存在触控事件，并根据该红外线接收器接收到的红外线来判断非弯曲方向上的触控坐标；That is to say, in a specific embodiment, the infrared transmitter and the infrared receiver are arranged side by side, and the infrared transmitter and the infrared receiver are in one-to-one correspondence; the processing unit 13 passes Judging whether the infrared rays received by the infrared receiver are blocked to determine whether there is a touch event in the non-bending direction, and judging the touch coordinates in the non-bending direction according to the infrared rays received by the infrared receiver;
所述红外线发射器的个数和所述红外线接收器的个数取决于曲面显示面板的触控分辨率的要求。The number of the infrared emitters and the number of the infrared receivers depends on the touch resolution requirements of the curved display panel.
如图2所示，本发明所述的触控装置的第一具体实施例应用于的曲面显示面板20包括相对设置的上侧边201和下侧边202，由图2可知，所述上侧边201和所述第二侧边202为弯曲的侧边；As shown in FIG. 2 , the curved display panel 20 to which the first embodiment of the touch control device according to the present invention is applied includes an upper side 201 and a lower side 202 which are oppositely arranged. As can be seen from FIG. 2 , the upper side The side 201 and the second side 202 are curved sides;

红外线发射器和红外线接收器的设置的密度取决于曲面显示面板的触控分辨率的要求；The arrangement density of the infrared emitter and the infrared receiver depends on the requirement of the touch resolution of the curved display panel;
如图2所示，所述触控波发射模块包括沿着上侧边201从左至右依次设置的第一红外线发射器211、第二红外线发射器212、第三红外线发射器213、第四红外线发射器214、第五红外线发射器215、第六红外线发射器216、第七红外线发射器217和第八红外线发射器218；As shown in FIG. 2 , the touch wave emitting module includes a first infrared emitter 211 , a second infrared emitter 212 , a third infrared emitter 213 , a fourth An infrared emitter 214, a fifth infrared emitter 215, a sixth infrared emitter 216, a seventh infrared emitter 217 and an eighth infrared emitter 218;
所述触控波接收模块包括沿着下侧边202依次设置的第一红外线接收器221、第二红外线接收器222、第三红外线接收器223、第四红外线接收器224、第五红外线接收器225、第六红外线接收器226、第七红外线接收器227和第八红外线接收器228；The touch wave receiving module includes a first infrared receiver 221, a second infrared receiver 222, a third infrared receiver 223, a fourth infrared receiver 224, and a fifth infrared receiver arranged sequentially along the lower side 202. 225, the sixth infrared receiver 226, the seventh infrared receiver 227 and the eighth infrared receiver 228;
所述第一红外线发射器211向所述第一红外线接收器221发射红外光，通过判断所述第一红外线接收器221接收到的红外光是否被遮挡而判断是否存在触控事件，依次类推，即一所述红外线发射器对应一红外线接收器；The first infrared transmitter 211 transmits infrared light to the first infrared receiver 221, and determines whether there is a touch event by judging whether the infrared light received by the first infrared receiver 221 is blocked, and so on, That is, one infrared transmitter corresponds to one infrared receiver;
在所述曲面显示面板20上，沿着弯曲方向还从上至下设置有多条触控扫描/感应线，在本发明所述的触控装置的第一具体实施例中，在弯曲方向上采用投射电容式自容式触控方式；On the curved display panel 20, a plurality of touch scanning/sensing lines are arranged from top to bottom along the curved direction. In the first specific embodiment of the touch device according to the present invention, in the curved direction Using projected capacitive self-capacitive touch mode;
如图2所示，在所述曲面显示面板20上，从上至下依次设置有第一触控扫描/感应线231、第二触控扫描/感应线232、第三触控扫描/感应线233、第四触控扫描/感应线234、第五触控扫描/感应线235、第六触控扫描/感应线236和第七触控扫描/感应线237；As shown in FIG. 2, on the curved display panel 20, a first touch scanning/sensing line 231, a second touch scanning/sensing line 232, and a third touch scanning/sensing line are sequentially arranged from top to bottom. 233. The fourth touch scanning/sensing line 234, the fifth touch scanning/sensing line 235, the sixth touch scanning/sensing line 236, and the seventh touch scanning/sensing line 237;
本发明所述的触控装置的第一具体实施例仅需要设置一层触控电极层(该触控电极层上仅需设有沿着弯曲方向设置的多条触控扫描/感应线)，而在相对容易实现触控的非弯曲方向上采用红外触控技术(无需设置触控电极)，即可以实现大尺寸曲面显示，工艺制程简单，成本低。The first specific embodiment of the touch device described in the present invention only needs to be provided with one touch electrode layer (the touch electrode layer only needs to be provided with a plurality of touch scanning/sensing lines arranged along the bending direction), However, using infrared touch technology in the non-curved direction, which is relatively easy to realize touch control (no need to set touch electrodes), can realize large-size curved surface display, with simple process and low cost.
本发明所述的触控装置的第一具体实施例在曲面弯曲方向上采用的投射电容式自容式触控结构的实现方式可选Add-on(外挂式)、In-cell(内嵌式)或On-cell(外置式)，由于在结构上仅需要在曲面弯曲方向上布设触控扫描/感应线，因此在设计上难度大大下降，成品良率及成本相对于传统双向实现方式均会有较大程度的优势。In the first specific embodiment of the touch device according to the present invention, the projected capacitive self-capacitive touch structure adopted in the curved direction of the curved surface can be implemented in Add-on (external plug-in), In-cell (embedded) ) or On-cell (external), since the structure only needs to lay touch scanning/sensing lines in the curved direction of the curved surface, the difficulty of design is greatly reduced, and the yield and cost of the finished product will be lower than the traditional two-way implementation. have a greater degree of advantage.
具体的，根据另一种具体实施方式，当所述触控波具体包括红外线时，所述触控波发射模块可以包括N个红外线发射器，所述触控波接收模块可以包括M个红外线接收器；N和M都为正整数，N小于M；Specifically, according to another specific implementation manner, when the touch wave specifically includes infrared rays, the touch wave transmitting module may include N infrared transmitters, and the touch wave receiving module may include M infrared receivers device; both N and M are positive integers, and N is less than M;
每一红外线发射器依次扫描至少一个红外线接收器；Each infrared transmitter sequentially scans at least one infrared receiver;
所述N个红外线发射器分别设置于所述第一侧边和所述第二侧边，所述M个红外线接收器分别设置于所述第一侧边和所述第二侧边；The N infrared transmitters are respectively arranged on the first side and the second side, and the M infrared receivers are respectively arranged on the first side and the second side;
也即，红外线发射器和红外线接收器采用对侧混合排布的方式，并采用一个红外线发射器依次扫描多个红外线接收器的形式，其优点是减少了红外线发射器的个数，但是红外线发射器需要预先设定多个扫描位置并提升触控扫描频率，且这种扫描方式在红外线发射器和红外线接收器的排布方式上只能采用对向放置的方式(如果同向放置，红外线发射器少而红外线接收器多，那么在靠近红外线发射器的这边的屏幕，必然会有“盲区”出现)。That is to say, the infrared transmitter and the infrared receiver are arranged in a mixed manner on the opposite side, and one infrared transmitter scans multiple infrared receivers in sequence, which has the advantage of reducing the number of infrared transmitters, but the infrared transmitter The sensor needs to pre-set multiple scanning positions and increase the touch scanning frequency, and this scanning method can only be placed in opposite directions in the arrangement of the infrared transmitter and infrared receiver (if placed in the same direction, the infrared transmitter If there are fewer infrared receivers and more infrared receivers, then there must be a "blind area" on the screen near the infrared transmitter).
如图3所示，本发明所述的触控装置的第二具体实施例应用于曲面显示面板30；As shown in FIG. 3 , the second specific embodiment of the touch device described in the present invention is applied to a curved display panel 30 ;

The curved side is perpendicular and parallel to the non-curved side for touch location.
本发明所述的触控装置的该具体实施例在实际应用中会存在下列问题：存在受限区域(Restricted Area)，这是因为：表面声波发射器发射的表面声波并不能沿实际弧线传播，而在弧线顶端连线以内区域，存在着一个受限区域，如果在扫描过程中，此区域出现障碍物，则容易造成表面声波方向上触控事件的误识别，同理，表面声波接收器端也会存在这样一个受限的弧面区域。This specific embodiment of the touch device described in the present invention has the following problems in practical application: there is a restricted area (Restricted Area), this is because: the surface acoustic wave emitted by the surface acoustic wave emitter cannot propagate along the actual arc , and there is a restricted area within the line at the top of the arc.
