具体实施方式
为了解决目前显示器的OSD菜单物理按键引起的操作繁琐问题,提升用户工作效率(如快速切换应用场景)，实现产品的真正无边框设计以及增加触控体验等，本公开提供了一种在显示面板上增加局部触控区域，从而取代OSD菜单的触控显示器解决方案。具体而言，本公开通过在显示面板增加触控设计，即电路上增加触控功能电路设计，在常规显示器的部分区域建立触控功能，如显示器右侧1/4区域，从而实现取代OSD物理按键和增加用户触控功能体验。同时，局部触控显示器相对于全屏触控显示器，其成本优势明显，使用范围更广泛，具有更高的市场价值，能够快速实现产品应用。
根据本公开的一个方面，提供了一种显示面板，如图1所示为根据本公开的实施例的一种显示面板的示意图。如图1所示，该显示面板10包括显示区域，显示区域包括至少一个触控区11和至少一个非触控区12。至少一个触控区11被配置为在被触摸时显示至少一个触控按钮13。该至少一个触控按钮13被配置为在被触摸时，使得在至少一个触控区11中显示能够进行触控操作的预定画面。该能够进行触控操作的预定画面(屏幕菜单，例如，OSD菜单)可包括多个触控按键，以通过触控方式对显示面板10进行参数调节。也就是说，显示面板10的显示区域可至少划分为两个显示区域，其中一个可以为触控区11，在该区域中可进行触控操作；另一个可以为非触控区12，在该区域仅能进行常规显示，而不能进行触控操作。该至少一个触控按钮13和包括多个触控按键的预定画面，可通过触控调整存储器中的控制信息进而来驱动该显示区域进行显示，例如显示亮度变化。可选地，至少一个触控区11的面积可为显示区域的面积的1/4，至少一个触控区11可位于显示区域的靠近显示面板的边缘的一侧。
至少一个触控区11被配置为在被触摸时显示能够进行触控操作的预定画面(例如，屏幕控制菜单)，由于可对触控区11进行触控操作，因此，本公开可以取代OSD物理按键而采用触控菜单方式来对显示面板的参数(例如，亮度、对比度等)进行调节，从而提高用户功能体验。进一步地，还可以以进度条方式设置屏幕菜单的参数调节方式，以进一步提高用户功能体验。并且，屏幕菜单还可以包括其它功能按键，例如手写文字输入、功能提示等按键。通过采用相应的控制算法，触控区11可实现相关技术中触控面板能够实现的任意操作。
可选地，该显示面板10还包括：时序控制寄存器TCON(Timer Control Register)22、微控制器MCU(Microprogrammed Control Unit)23、电源管理集成电路25和触控集成电路TPIC(Touch Integrated Circuit For Panel)24，用于实现本公开的非触控区的显示功能以及触控区的触控显示功能。如图1和图5所示，时序控制寄存器22被配置为在触控阶段(例如显示面板的时间同步信号Tsync的低电平阶段)时，输出触控使能信号Touch_EN和栅极使能信号GATE_EN。微控制器23被配置为在触控使能信号Touch_EN的控制下，输出触控时钟同步信号Touch sync和脉冲宽度调制波PWM。电源管理集成电路25被配置为输出公共电压信号。触控集成电路24被配置为在触控时钟同步信号Touch sync的控制下，基于脉冲宽度调制PWM波和公共电压信号，输出第一冗余寄生电容信号VCOM_M，以及基于栅极使能信号GATE_EN输出第二冗余寄生电容信号GATE_M。该第一冗余寄生电容信号VCOM_M和第二冗余寄生电容信号GATE_M用于消除显示面板上的寄生电容。通常，显示面板设置有时间同步信号Tsync，在本公开中，以时间同步信号Tsync的高电平阶段作为显示阶段，时间同步信号Tsync的低电平阶段作为触控阶段，来对本公开进行详细说明，但本公开并不限于此。
图2为根据本公开的实施例的一种显示面板的结构示意图。如图2所示，显示面板10还包括在显示区域中的呈多行多列排布的多 个像素单元21和多条第一信号线31。图2仅示出显示面板10的触控区11中的呈多行多列排布的多个像素单元21，但是，已知的是，在非触控区12中也设置有呈多行多列排布的多个像素单元21。
至少一个触控区11可被划分为多个感测分区14(感测块)。多个感测分区14中的每一个包括相邻选定数量的像素单元21，并且多个感测分区14分别与多条第一信号线31一一对应，每一个感测分区14中的各像素单元的公共电极分别连接至相应的第一信号线31。图3A为根据本公开的实施例的触控区的感测分区的结构示意图，图3B为根据本公开的实施例的触控区的像素单元的结构示意图。如图3A所示，触控区11包括45x10个感测分区14，在显示阶段，通过多条第一信号线31中的一条向相应一个感测分区14中的各像素单元提供公共电压信号。在本公开中，在显示阶段，通过一条第一信号线31向一个感测分区14提供公共电压信号，即触控区11的感测分区14的数量等于第一信号线31的数量。也就是说，在触控区11，多个感测分区14中的每一个中的各像素单元21的公共电极(公共电压层)可以是一体形成的，而各感测分区14的公共电极是彼此独立的，因此需分别向各感测分区14提供公共电压信号。如图3B所示，左侧示图示出一个像素单元可包括红色(R)、绿色(G)和蓝色(B)三个子像素，右侧示图示出对应的剖面结构图，其包括依次设置的玻璃基底、公共电极层(VCOM)层、像素单元和彩膜基底。
可选地，该显示面板10还包括一条第二信号线32，至少一个非触控区12中的多个像素单元21均连接至该第二信号线32，如图2所示。也就是说，在至少一个非触控区12，各像素单元21的公共电压层可以一体形成，只需提供一个公共电压信号即可。

可选地，该显示面板还包括栅极驱动电路28和至少一个源极驱动电路27。如图2所示，栅极驱动电路GIP/GOP(Gate In Panel/Gate On Panel)28与触控集成电路24连接，并通过多条栅线33与显示面板中的多个像素单元行分别连接，被配置为在显示阶段基于触控集成电路24输出的栅极电压信号GATE

本公开通过在显示面板增加触控设计，即电路上增加触控功能电路设计，在常规显示器的部分区域建立触控功能，从而实现取代OSD物理按键和增加用户触控功能体验。同时，局部触控显示器相对于全屏触控显示器，其成本优势明显，使用范围更广泛，具有更高的市场价值，能够快速实现产品应用。
根据本公开的一个方面，还提供了一种显示装置，其包括以上所述的显示面板以及用于驱动该显示面板的外围驱动电路。本公开的显示装置例如可为LCD(Liquid Crystal Display)触控显示装置，通过采用上述显示面板，可以实现取代OSD物理按键和增加用户触控功能体验，并且其成本优势明显，使用范围更广泛，具有更高的市场价值，能够快速实现产品应用。
根据本公开的另一方面，还提供了一种显示面板的驱动方法。图4为根据本公开的实施例的显示面板的驱动方法流程图，图5为根据本公开的实施例的显示面板的驱动时序图，以下参考图2、图4和图5来对本公开的显示面板的驱动方法进行详细说明。如图4所示，本公开的驱动方法包括步骤S110至S120。
在步骤S110中，触摸位于显示面板的显示区域中至少一个触控区中的触控按钮。具体地，在该阶段，触摸显示区域中的至少一个触控区中的触控按钮，由此产生针对该触控按钮的触摸信号。
在步骤S120中，基于对触控按钮的触摸，在至少一个触控区中显示能够进行触控操作的的预定画面。可选地，预定画面包括多个触控按键。具体地，在该阶段，基于所接收的触摸信号，可以在至少一个触控区中显示包括多个触控按键的预定画面，例如屏幕菜单。并且，在该显示预定画面的过程中，非触控区的显示画面不发生变化。
以下参考图2、图4和图5，来对本公开的显示面板的触控阶段和显示阶段的驱动方法分别进行详细说明。
在显示面板的触控阶段，首先，时序控制寄存器22输出触控使能信号Touch_EN和栅极使能信号GATE_EN。然后，微控制器23在触控使能信号Touch_EN的控制下，输出触控时钟同步信号Touch sync和脉冲宽度调制波PWM。然后，电源管理集成电路25输出公共电压信号。然后，触控集成电路24在触控时钟同步信号Touch sync的控制下，基于公共电压信号和脉冲宽度调制波PWM输出第一冗余寄生电容信号VCOM_M，以及基于栅极使能信号GATE_EN输出第二冗余寄生电容信号GATE_M。如图5所示，在时间同步信号Tsync的低电平阶段V_Blanking，通过触控集成电路24向SRIC7和SRIC8输出方波形式的第一冗余寄生电容信号VCOM_M。该方波形式的第一冗余寄生电容信号VCOM_M可通过直流公共电压信号和脉冲宽度调制波PWM叠加形成。第二冗余寄生电容信号GATE_M由触控集成电路基于栅极使能信号GATE_EN生成。该第一冗余寄生电容信号VCOM_M和第二冗余寄生电容信号GATE_M用于消除显示面板上的寄生电容。
接下来，通过与至少一个感测子电路261连接的多路复用器263和多条第一信号线31、以及通过与至少一个源极运算放大器262连接的多路复用器263，分别将第一冗余寄生电容信号VCOM_M输入至显示面板的至少一个触控区的各像素单元的公共电极和数据线34。然后，通过栅极驱动电路28将第二冗余寄生电容信号GATE_M输入至显示面板的至少一个触控区11的各像素单元的栅线。最后，至少一个感测子电路261基于微控制器输出的触控时钟同步信号Touch sync和脉冲宽度调制波PWM，经由相应多路复用器通过多条第一信号线31感测对至少一个触控区11中的至少一个触控按钮13以及预定画面中的多个触控按键的触摸。
在感测到对至少一个触控区11中的至少一个触控按钮13以及预定画面中的多个触控按键的触摸之后，至少一个感测子电路261产生触摸信号，并通过串行外围设备接口如SPI(Serial Peripheral Interface)将该触摸信号发送至微控制器23，微控制器23进而将该 触摸信号通过SPI通过连接端口CNT发送至前端系统，进而实现对显示面板的参数调节。
在显示面板的显示阶段，首先，时序控制寄存器22输出显示使能信号Display_EN以及栅极使能信号GATE_EN。然后，微控制器23在显示使能信号Display_EN的控制下，输出时间同步信号Tsync。然后，电源管理集成电路25输出公共电压信号。然后，触控集成电路24在时间同步信号Tsync的控制下，输出由电源管理集成电路25提供的公共电压信号VCOM1，并且在栅极使能信号GATE_EN的控制下，输出栅极电压信号GATE。
接下来，通过并行执行如下操作来实现显示面板的显示画面的显示：通过与至少一个感测子电路261连接的多路复用器263和多条第一信号线31、以及通过与至少一个源极运算放大器262连接的多路复用器263，分别将来自触控集成电路24的公共电压信号VCOM1以及数据信号DATA输入至显示面板的至少一个触控区的各像素单元的公共电极和数据线；栅极驱动电路28基于触控集成电路24输出的栅极电压信号GATE，通过多条栅线分别向显示面板中的多个像素单元行提供栅极驱动信号；至少一个源极驱动电路27在微控制器23提供的时间同步信号Tsync的控制下，通过数据线向显示面板的至少一个非触控区11的多个像素单元列发送数据信号DATA；以及电源管理集成电路25还通过至少一个源极驱动电路27经由第二信号线32向至少一个非触控区12中的各像素单元提供公共电压信号VCOM2。公共电压信号VCOM1和公共电压信号VCOM2可以相等，并且可以均为直流信号。
如图5所示，在本公开中，以显示面板的时间同步信号Tsync为基准，将显示面板的工作过程划分为触控阶段Touch(其对应V_Blanking阶段)和显示阶段Display。触控阶段对应显示面板的时间同步信号的低电平阶段，显示阶段对应时间同步信号的高电平阶段。由图5可知，触控检测信号PWM为周期方波信号并且其周期小于时间同步信号的周期，触控使能信号对应时间同步信号的下降沿， 显示使能信号Display_EN对应时间同步信号的上升沿。
在本公开中，需注意的是，在第一触控阶段，触摸触控按钮13，在其后的第一显示阶段，在触控区11中显示包括触控按键的预定画面，而在非触控区依然显示之前的显示画面而不发生变化。在接下来的第二触控阶段，触摸预定画面中的触控按键，在其后的第二显示阶段，在触控区11和非触控区12中显示显示面板的参数被调节之后的显示画面，而包括触控按键的预定画面可以设置为自动隐藏。触控按钮13以及触控按键的预定画面的显示，可通过调用预先存储在存储器中的相应的显示画面数据来进行显示。
同时，如图5所示，在触控阶段，可通过栅极驱动电路提供周期方波形式的第一冗余寄存电容信号GATE_M(高电平VGL_H和低电平VGL_L)以消除显示面板部分寄存电容。在该触控阶段，第一冗余寄存电容信号GATE_M的幅度小于在显示阶段栅极驱动电路提供的栅极驱动信号(高电平VGH和低电平VGL)的幅度。触控阶段的第一冗余寄存电容信号GATE_M和显示阶段的栅极电压信号GATE均由触控集成电路24基于栅极使能信号GATE_EN生成，只是两者的幅值不同。其中，触控阶段的第一冗余寄存电容信号GATE_M不足以开启显示面板中的晶体管的栅极。
可选地，本公开的驱动方法还包括对至少一个触控区的亮度和至少一个非触控区的亮度进行均一性调整，例如通过亮度补偿、分区精确颜色控制等对显示面板的亮度进行均一性调整。
在本公开中，通过采用上述显示面板及其驱动方法，可以实现取代OSD物理按键和增加用户触控功能体验，并且使其成本降低，使用范围更广泛，具有更高的市场价值，能够快速实现产品应用。
可以理解的是，以上实施方式仅仅是为了说明本公开的原理而采用的示例性实施方式，然而本公开并不局限于此。对于本领域内的普通技术人员而言，在不脱离本公开的精神和实质的情况下，可以做出各种变型和改进，这些变型和改进也视为本公开的保护范围。
