请参阅图1，本申请实施方式的显示面板组件200包括触摸屏组件100和显示面板20。触摸屏30设置在显示面板20。
显示面板20可包括液晶显示面板、有机发光显示面板、等离子体显示面板及场发射显示面板。在图示的实施方式中，触摸屏30层叠在显示面板20上。可以理解，在其它实施方式中，触摸屏30可以形成在显示面板20内。
请一并参阅图2，本申请实施方式的触摸屏组件100包括触摸检测电路10和触摸屏30。触摸屏30包括多个触摸传感器Cji、多条行驱动线TX和多条列 接收线RX，每条行驱动线与一行触摸传感器连接，每条列接收线与一列触摸传感器连接。多个触摸传感器Cji呈阵列排布以形成触摸传感器阵列，i*j个触摸传感器排列成i列j行，其中，i，j为正整数，j表示触摸传感器Cji的行序数，而i表示触摸传感器Cji的列序数。
在本申请实施方式中，触摸传感器141是电容传感器，具体的，每条行驱动线TX与对应一行电容传感器的一个电极连接，每条列接收线RX与对应一列电容传感器的另一个电极连接。
本申请实施方式的显示面板组件200和触摸屏组件100，在确定触摸屏30在被弯折时，可对弯折引起的输出电压的变化不作触控处理，避免了将触摸屏30被弯折误认为触摸屏30被触摸，从而提高触控交互体验。具体地，显示面板可为柔性显示面板(如OLED显示面板)，触摸屏安装在柔性显示面板上时，会随着柔性显示面板的弯折而弯折。
请参阅图3和图4，本申请实施方式的触摸检测电路10包括驱动模块12、感应模块14和连接感应模块14的处理模块16。驱动模块12用于向触摸屏30提供驱动信号Vdriver。感应模块14用于产生触摸传感器141的输出电压Vout。处理模块16用于确定输出电压Vout与预设电压阈值Vref的差值绝对值是否大于预设值H，及在输出电压Vout与预设电压阈值Vref的差值绝对值大于预设值H时，用于确定整行或整列触摸传感器是否被触控，以及在整行或整列触摸传感器被触控时，用于确定触摸屏30被弯折。
本申请实施方式的触摸检测电路10，在确定触摸屏30被弯折时，可对弯折引起的输出电压的变化不作触控处理，避免了将触摸屏30被弯折误认为触摸屏30被触摸，从而提高触控交互体验。
可以理解，一般而言，当输出电压Vout与预设电压阈值Vref的差值绝对值大于预设值H时，可以确定触摸屏30被触摸。然而，除了被触摸之外，触摸屏30的弯折也会导致触摸传感器141的输出电压变化。也即是说，触摸屏30在被弯折时，有可能会出现输出电压Vout与预设电压阈值Vref的差值绝对 值大于预设值H的情形。因此，当某个触摸传感器141的输出电压Vout与预设电压阈值Vref的差值绝对值大于预设值H时，无法确定触摸屏30是在该触摸传感器141的对应位置被触摸，还是触摸屏30没有被触摸，只是被弯折。
另外，当触摸屏30被弯折时，一般是沿着行驱动线TX或列接收线RX的方向被弯折，而通常地用户不会同时触控整行的触摸传感器或整列的触摸传感器。因此，可以通过确定整行或整列触摸传感器141是否被触控，来确定触摸屏30是否弯折。这样，可以确定输出电压Vout的变化到底是由触摸引起的，还是由弯折引起的，并根据不同的情形对触摸屏30的输出电压进行处理，从而减少误触发的情况，提高触摸屏30的灵活性和稳定性。
请注意，图3中的触摸传感器141可以是图2中的触摸传感器阵列中的任意一个触摸传感器Cji，图2所示的每条列接收线RX都连接有图3中的电路。
具体地，驱动模块12通过行驱动线TX向触摸屏30提供驱动信号Vdriver，感应模块14通过列接收线RX输出触摸传感器Cji的输出而产生输出电压Vout。在一个例子中，图3中的触摸传感器141是图2中的触摸传感器阵列中的触摸传感器C23，驱动模块12通过行驱动线TX2向触摸传感器C23提供驱动信号Vdriver，感应模块14通过列接收线RX3输出触摸传感器C23的输出。
另外，触摸屏组件100中，触摸屏30连接驱动模块12和感应模块14。
此外，在本申请实施方式中，预设电压阈值Vref为触摸屏30既没有被触控也没有被弯折时的输出电压Vout，预设值H的具体数值可以通过实际取样确定。在一个例子中，预设值H的数值可设置为预设电压阈值Vref的10％。
可以理解，预设值H可以看成是触摸传感器在没被触控时所输出的输出电压Vout的噪声范围，在这个范围内，输出电压Vout的大小波动都可被看成是实际上触摸传感器并未被触控。
处理模块16包括计数单元162和调节单元164。
计数单元162的计数值在触摸检测电路10的每个扫描周期T的初始值为0，计数单元162连接感应模块14并用于在一个扫描周期T内输出电压Vout大于 或等于预设电压阈值Vref时，使计数值加1；处理模块16用于确定计数值是否大于0并用于在计数值大于0时，确定输出电压Vout与预设电压阈值Vref的差值绝对值是否大于预设值H。
如此，实现统计一个扫描周期T内输出电压Vout大于或等于预设电压阈值Vref的次数。可以理解，正常无外界干扰情况下，输出电压Vout不会超过预设电压阈值Vref的幅值，此时计数值为0，处理模块16用于在计数值等于0时，确定触摸屏30既没有被弯折也没有被触摸。当计数值大于0时，才有必要去确定输出电压Vout与预设电压阈值Vref的差值绝对值是否大于预设值H。请注意，如前所述，外界干扰可能是触摸屏30被弯折，也可能是触摸屏30被触摸。
具体地，计数单元162包括第一比较器B1、计数器1622和第一电容C1。第一比较器B1的负向输入端与感应模块14的输出端连接以接收输出电压Vout，第一比较器B1的正向输入端用于输入预设电压阈值Vref，第一比较器B1的正向输入端与第一电容C1的第一端连接，第一电容C1的第二端接地，第一比较器B1的输出端与计数器1622连接，计数器1622用于根据第一比较器B1的输出调节计数值。
进一步地，输出电压Vout每达到预设电压阈值Vref一次，也即是输出电压Vout每达到或超过预设电压阈值Vref的幅值一次，第一比较器B1就会输出高电平一次，计数器1622设置为上升沿触发有效，每当计数器1622接收到第一比较器B1送出的高电平信号，计数器1622就计数1次。
在某些实施方式中，处理模块16用于当每条列接收线在同一时刻输出的输出电压Vout与预设电压阈值Vref的差值绝对值均大于预设值H时，确定整行触摸传感器Cji被触控以及用于当同一条列接收线在触摸检测电路10的一个扫描周期T内输出的每个输出电压Vout与预设电压阈值Vref的差值绝对值均大于预设值H时，确定整列触摸传感器Cji被触控。如此，实现确定整行或整列触摸传感器141是否被触控。
调节单元164连接计数单元162，调节单元164用于在确定触摸屏30被弯 折时，调节预设电压阈值Vref以使输出电压Vout与调节后的预设电压阈值Vrefx的差值绝对值不大于预设值H。
如此，实现通过调节单元164调节预设电压阈值Vref。请注意，此处调节后的预设电压阈值用Vrefx表示，以表明调节后的预设电压阈值Vrefx与预设电压阈值Vref在数值上不同。
具体地，可以通过公式Vrefx＝Vref+a来将预设电压阈值Vref调节为调节后的预设电压阈值Vrefx。其中，预设电压阈值Vref在数值上等于触摸屏30既没有被触控也没有被弯折时的输出电压Vout，a为对预设电压阈值Vref进行调节的调节量。
可以理解，如前所述，当输出电压Vout与预设电压阈值Vref的差值绝对值大于预设值H时，可以确定触摸屏30被触摸。而当触摸屏30被弯折时，即使触摸屏30没有被触摸，输出电压Vout与预设电压阈值Vref的差值绝对值也会大于预设值H。
因此，需要调整预设电压阈值Vref，以使输出电压Vout与调节后的预设电压阈值Vrefx的差值绝对值不大于预设值H，这样来补偿由弯折引起的输出电压Vout与预设电压阈值Vref的差值绝对值的变化，使得在触摸屏30被弯折时，不会因输出电压Vout与调节后的预设电压阈值Vrefx的差值绝对值大于预设值H而误判触摸屏30被触摸。
另外，在调整了预设电压阈值Vref之后，如果输出电压Vout与调节后的预设电压阈值Vrefx的差值绝对值大于预设值H，那么可以确定触摸屏30在弯折处被触摸。
进一步地，调节单元164包括第二比较器B2和电容调节件1642。第二比较器B2的正向输入端连接计数单元162，第二比较器B2的正向输入端连接电容调节件1642的第一端，第二比较器B2的输出端连接电容调节件1642的第二端，第二比较器B2的负向输入端接地，电容调节件1642用于调节自身的电容大小以调节预设电压阈值Vref。
第二比较器B2为过零比较器，反向输入端接地，当预设电压阈值Vref＞0时第二比较器B2输出高电平，当预设电压阈值Vref＜0时，第二比较器B2输出低电平。
进一步地，请参阅图5，电容调节件1642包括并联的多个支路，每个支路包括串联的电容Ck和开关k。如此，可以通过控制开关k的开闭来控制电容Ck是否接入调节单元164从而调节预设电压阈值Vref。
在图5的示例中，电容调节件1642包括并联的n个支路，开关k和电容Ck均有n个，第一条支路包括串联的开关k1和电容Ck1，第二条支路包括串联的开关k2和电容Ck2……第n条支路包括串联的开关kn和电容Ckn。
请再次参阅图3，感应模块14包括信号放大器142、第二电容C2和开关K1，信号放大器142的负向输入端连接触摸传感器141、第二电容C2的第一端和开关K1的第一端，信号放大器142的输出端连接第二电容C2的第二端、开关K1的第二端和处理模块16。
如此，实现感应模块14的基本构造。在触摸检测电路10中，触摸传感器141的电容与输出电压Vout在一定范围内成正相关，在一定范围内(如0.5pF-5pF)，触摸传感器141的电容越大，输出电压Vout也越大。
具体地，开关K1可以控制第二电容C2是否连通在信号放大器142的负向输入端和信号放大器142的输出端之间。可以理解，开关K1与第二电容C2并联，开关K1断开时，第二电容C2连通在信号放大器142的负向输入端和信号放大器142的输出端之间。开关K1闭合时，虽然第二电容C2连接在信号放大器142的负向输入端和信号放大器142的输出端之间，但是第二电容C2被开关K1短接，使得第二电容C2没有导通在信号放大器142的负向输入端和信号放大器142的输出端之间，第二电容C2对信号放大器142的输出端输出的输出电压Vout没有影响。
当触摸检测电路10初始化时，开关K1闭合，在触摸检测电路10检测时，开关K1断开。驱动信号Vdriver上升过程中，为触摸传感器141充电，由于运 放的虚短虚断的原理，信号放大器142输出的输出电压Vout会下降，对第二电容C2充同样多的电荷来保证信号放大器142的正向输入端保持电位。在一个例子中，信号放大器142可为运算放大器。
感应模块14包括第一电阻R1、第二电阻R2、第三电容C3和第四电容C4，触摸传感器141的第一端连接第一电阻R1的第一端和第三电容C3的第一端，触摸传感器141的第二端连接第二电阻R2的第一端和第四电容C4的第一端，第一电阻R1的第二端连接信号放大器142的负向输入端，第二电阻R2的第二端用于接收驱动信号Vdriver，第三电容C3的第二端和第四电容C4的第二端均接地。
具体地，在图3的示例中，第三电容C3为感应通道对地电容，第四电容C4为驱动通道对地电容。第一电阻R1为感应通道电阻，第二电阻R2为驱动通道电阻，第一电阻R1和第二电阻R2在数值上需要满足触摸检测电路10的驱动能力范围。
感应模块14包括第三电阻R3和第四电阻R4，第三电阻R3的第一端连接第四电阻R4的第一端和信号放大器142的正向输入端，第三电阻R3的第二端用于与电源连接，第四电阻R4的第二端接地。
具体地，在图3的示例中，第三电阻R3与第四电阻R4相等，从而为信号放大器142的正向输入端提供二分之一的偏置电压。
