相应的,本申请实施例还提供一种显示装置,包括如前述任一实施例中的触控显示面板。
有益效果:本申请实施例的触控显示面板,通过触控生成电路在触控阶段中根据同步控制信号输出与数据信号同相位且不同幅值的触控信号至触控电极,可以在触控阶段中保持像素电极与公共电极之间的压差一致,也就是说,在触控阶段中液晶夹压保持不变,改善或者避免了横纹这样的显示异常。
在触控显示面板中,如图1所示,显示过程包括显示阶段DP1和触控阶段TP1,由于触控信号TPDO/TPDE/TPCOM的电位不论是在显示阶段DP1还是触控阶段TP1均保持恒定,导致在触控阶段TP1中像素电极具有的数据信号DS的电位与触控信号TPDO/TPDE/TPCOM的电位之差发生变化,而接收触控信号TPDO/TPDE/TPCOM的触控电极与公共电极为同一电极,致使像素电极与公共电极之间的压差即液晶夹压发生变化,进而导致横纹这样的显示异常。
有鉴于上述提及的在触控阶段TP1中液晶夹压不一致导致显示异常的技术问题,本实施方式提供了一种触控显示面板,请参阅图2至图8,如图2、图3和图4所示,该触控显示面板包括公共电极、提供数据信号DS的像素电极、提供恒定电压信号P_COM的恒压传输线,以及触控生成电路,公共电极复用为触控电极;触控生成电路在触控阶段TP1中根据同步控制信号T_SYNC输出与数据信号DS同相位且不同幅值的触控信号TPDO/TPDE/TPCOM至触控电极。
可以理解的是,本实施方式提供的触控显示面板,通过触控生成电路在触控阶段TP1中根据同步控制信号T_SYNC输出与数据信号DS同相位且不同幅值的触控信号TPDO/TPDE/TPCOM至触控电极,可以在触控阶段TP1中保持像素电极与公共电极之间的压差一致,也就是说,在触控阶段TP1中液晶夹压保持不变,改善或者避免了横纹这样的显示异常。
在其中一个实施方式中,如图2所示,触控显示面板还包括直流电压转换器、电平转换芯片、数据驱动芯片、像素阵列、时序控制器、闪存、输入连接器、微控制器(Microcontroller Unit,MCU)、发光二极管转换器以及背光单元中的至少一个。
其中,输入连接器分别与时序控制器、微控制器、直流电压转换器以及发光二极管转换器电连接,以实现时序控制器通过eDP(Embedded DisplayPort)协议和/或I2C(Inter-Integrated Circuit)协议接收对应的信号,并为微控制器提供3.3V的直流电压,以及提供多种不同规格的电源信号,以及为发光二极管转换器提供输入信号以驱动背光单元提供对应的背光。
其中,微控制器可以通过I2C协议与时序控制器进行通信。时序控制器控制电平转换芯片和数据驱动芯片按照既定的内容进行工作,以驱动像素阵列显示预期的画面。直流电压转换器为电平转换芯片和数据驱动芯片提供对应的电压。
而为了提高减少触控生成电路的占用空间,触控生成电路可以集成于直流电压转换器、电平转换芯片以及数据驱动芯片中的至少一个中,或者,也可以集成于时序控制器、直流电压转换器、发光二极管转换器或者背光单元中。
在其中一个实施方式中,如图3所示,触控生成电路包括放大模块100和选择模块200,放大模块100的输入端与像素电极电连接;选择模块200的第一输入端与放大模块100的输出端电连接,选择模块200的第二输入端与恒压传输线电连接,选择模块200的控制端接入同步控制信号T_SYNC,选择模块200的输出端输出触控信号TPDO/TPDE/TPCOM。
需要进行说明的是,同步控制信号T_SYNC可以由时序控制器输出,也可以由其他的控制电路生成。例如,在显示阶段DP1中同步控制信号T_SYNC的电位为高电位的情况下,触控生成电路输出恒定电压信号P_COM为触控信号TPDO/TPDE/TPCOM;或者,在触控阶段TP1中同步控制信号T_SYNC的电位为低电位的情况下,触控生成电路输出同相位且不同幅值的数据信号DS为触控信号TPDO/TPDE/TPCOM,以保持数据信号DS与触控信号TPDO/TPDE/TPCOM之间的压差在触控阶段TP1中保持不变。
在其中一个实施方式中,如图4所示,触控生成电路在显示阶段DP1中还根据同步控制信号T_SYNC生成与恒定电压信号P_COM相同幅值的触控信号TPDO/TPDE/TPCOM。
需要进行说明的是,数据信号DS的脉冲幅值可以但不限于为5V,也可以为其他数值的电压;数据信号DS的低电位可以但不限于为0V,还可以为其他数值的电压。
在其中一个实施方式中,如图5所示,放大模块100包括第一反向放大单元101和第二反向放大单元102,第一反向放大单元101的输入端与像素电极电连接;第二反向放大单元102的输入端与第一反向放大单元101的输出端电连接,第二反向放大单元102的输出端与选择模块200的第一输入端电连接。
需要进行说明的是,第一反向放大单元101用于反向放大接入的数据信号DS,第二反向放大单元102用于反向放大第一反向放大单元101处理后的数据信号DS,如此既保证了数据信号DS的放大效果,又通过两次反向实现了数据信号DS的同向。也就是说,本实施方式实现了数据信号DS的同向放大。
在其中一个实施方式中,如图5所示,第一反向放大单元101包括第一电容C1、第一电阻R1、第一放大器AP1、第二电阻R2、第三电阻R3以及第四电阻R4,第一电容C1的一端与像素电极电连接;第一电阻R1的一端与第一电容C1的另一端电连接;第一放大器AP1的反相输入端与第一电阻R1的另一端电连接;第二电阻R2的一端与第一电阻R1的另一端电连接,第二电阻R2的另一端与第一放大器AP1的输出端电连接;第三电阻R3的一端与第一电源端VCC电连接,第三电阻R3的另一端与第一放大器AP1的同相输入端电连接;第四电阻R4的一端与第一放大器AP1的同相输入端电连接,第四电阻R4的另一端与接地端GND电连接。
需要进行说明的是,第一反向放大单元101用于反向放大接入的数据信号DS。若图6所示的数据信号DS具有正脉冲,则第一反向放大单元101的输出信号即节点BB1的电位波形具有负脉冲,且脉冲幅值可以大于数据信号DS的脉冲幅值。
在其中一个实施方式中,如图5所示,第二反向放大单元102包括第五电阻R5、第二放大器AP2、第六电阻R6以及第七电阻R7,第五电阻R5的一端与第一放大器AP1的输出端电连接;第二放大器AP2的反相输入端与第五电阻R5的另一端电连接;第六电阻R6的一端与第二放大器AP2的反相输入端电连接,第六电阻R6的另一端分别与第二放大器AP2的输出端和选择模块200的第一输入端电连接;第七电阻R7的一端与第二放大器AP2的同相输入端电连接,第七电阻R7的另一端与接地端GND电连接。
需要进行说明的是,第二反向放大单元102用于反向放大第一反向放大单元101处理后的数据信号DS。若图6所示的第一反向放大单元101的输出信号即节点BB1的电位波形具有负脉冲,则第二反向放大单元102的输出信号即节点CC1的电位波形具有与数据信号DS相同的正脉冲,且脉冲幅值可以大于数据信号DS的脉冲幅值。
需要进行说明的是,结合图5和图6所示,数据信号DS和节点BB1的电位波形以及节点CC1的电位波形在触控阶段TP1和显示阶段DP1中均分别相同。不同的是,在触控阶段TP1中,通过同步控制信号T_SYNC对选择模块200的控制可以选择数据信号DS作为触控信号TPDO/TPDE/TPCOM,因此,触控信号TPDO/TPDE/TPCOM与数据信号DS的相位相同而脉冲幅值不同,以保持像素电极与公共电极之间的液晶夹压在触控阶段TP1中保持不变;而在显示阶段DP1中,可以通过同步控制信号T_SYNC对选择模块200的控制可以选择恒定电压信号P_COM作为触控信号TPDO/TPDE/TPCOM,以进行对应的显示。
在其中一个实施方式中,如图7所示,放大模块100包括第八电阻R8、第三放大器AP3、第九电阻R9、第十电阻R10以及第十一电阻R11,第八电阻R8的一端与偏置电压端电连接;第三放大器AP3的反相输入端与第八电阻R8的另一端电连接;第九电阻R9的一端与第三放大器AP3的反相输入端电连接,第九电阻R9的另一端分别与第三放大器AP3的输出端和选择模块200的第一输入端电连接;第十电阻R10的一端与像素电极电连接,第十电阻R10的另一端与第三放大器AP3的同相输入端电连接;第十一电阻R11的一端与第三放大器AP3的同相输入端电连接,第十一电阻R11的另一端与接地端GND电连接。
需要进行说明的是,本实施方式能够在保持数据信号DS的相位不变的情况下正向放大脉冲幅值,同样能够输出与数据信号DS的相位相同且脉冲幅值不同的触控信号TPDO/TPDE/TPCOM。而且相较于图5所示,所使用元器件的数量更少,减少了成本及占用空间,还减少了数据信号DS的处理路径。
在其中一个实施方式中,如图5和图7所示,选择模块200包括数据选择器S2,数据选择器S2的第一输入端与放大模块100的输出端电连接,数据选择器S2的第二输入端与恒压传输线电连接,数据选择器S2的选择端接入同步控制信号T_SYNC,数据选择器S2的输出端输出触控信号TPDO/TPDE/TPCOM。
需要进行说明的是,若图8所示的数据信号DS具有正脉冲,则放大模块100的输出信号即节点CC2的电位波形具有与数据信号DS相同的正脉冲,且脉冲幅值可以大于数据信号DS的脉冲幅值。
结合图7和图8所示,数据信号DS以及节点CC2的电位波形在触控阶段TP1和显示阶段DP1中均分别相同。不同的是,在触控阶段TP1中,通过同步控制信号T_SYNC对选择模块200的控制可以选择数据信号DS作为触控信号TPDO/TPDE/TPCOM,因此,触控信号TPDO/TPDE/TPCOM与数据信号DS的相位相同而脉冲幅值不同,以保持像素电极与公共电极之间的液晶夹压在触控阶段TP1中保持不变;而在显示阶段DP1中,可以通过同步控制信号T_SYNC对选择模块200的控制可以选择恒定电压信号P_COM作为触控信号TPDO/TPDE/TPCOM,以进行对应的显示。
其中,在触控阶段TP1中数据信号DS与触控信号TPDO/TPDE/TPCOM之间的压差可以大于0V,例如,3V~6V,具体地,可以为4.8V、5.0V或5.2V等,需要进行说明的是,该压差的范围或者具体值可选地应用于液晶显示面板中。
在其中一个实施方式中,本实施方式提供一种显示装置,该显示装置包括上述至少一个实施方式中的触控显示面板,触控显示面板为触控液晶显示面板。
显示装置还包括存储器和处理器;所述存储器上存储有可在处理器上运行的计算机程序。上述存储器包括:ROM、RAM或磁碟或者光盘等各种可以存储程序代码的介质。
示例的,该显示装置可以为:智能手表、智能手环、手机、平板电脑或笔记本电脑等任何具有触控显示功能的产品或部件。
可以理解的是,由于本实施方式提供的显示装置包括了上述至少一个实施方式中的触控显示面板,同样能够通过触控生成电路在触控阶段TP1中根据同步控制信号T_SYNC输出与数据信号DS同相位且不同幅值的触控信号TPDO/TPDE/TPCOM至触控电极,可以在触控阶段TP1中保持像素电极与公共电极之间的压差一致,也就是说,在触控阶段TP1中液晶夹压保持不变,改善或者避免了横纹这样的显示异常。
