下面将结合本申请实施例中的附图,对本申请实施例中的技术方案进行清楚、完整地描述。显然,所描述的实施例仅仅是本申请一部分实施例,而不是全部的实施例。基于本申请中的实施例,本领域技术人员在没有作出创造性劳动前提下所获得的所有其他实施例,都属于本申请保护的范围。
在本申请的描述中,需要理解的是,术语“中心”、“纵向”、“横向”、“长度”、“宽度”、“厚度”、“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“水平”、“顶”、“底”、“内”、“外”、“顺时针”、“逆时针”等指示的方位或位置关系为基于附图所示的方位或位置关系,仅是为了便于描述本申请和简化描述,而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作,因此不能理解为对本申请的限制。此外,术语“第一”、“第二”仅用于描述目的,而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此,限定有“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多个所述特征。在本申请的描述中,“多个”的含义是两个或两个以上,除非另有明确具体的限定。
在本申请中,除非另有明确的规定和限定,第一特征在第二特征之“上”或之“下”可以包括第一和第二特征直接接触,也可以包括第一和第二特征不是直接接触而是通过它们之间的另外的特征接触。而且,第一特征在第二特征“之上”、“上方”和“上面”包括第一特征在第二特征正上方和斜上方,或仅仅表示第一特征水平高度高于第二特征。第一特征在第二特征“之下”、“下方”和“下面”包括第一特征在第二特征正下方和斜下方,或仅仅表示第一特征水平高度小于第二特征。
本申请实施例提供了一种液晶面板驱动电压极性反转方法,具体流程图如图1所示,将液晶面板栅线由上至下平均分为X个连续的栅线组,X为不小于2的整数;在一1/X帧的时间内,对于一栅线组,首先在1/2X帧的时间内,依次打开对应像素单元被施加第一数据电压信号的栅线行,向被打开的所述栅线行上的像素单元加载第一数据电压信号后,再在1/2X帧的时间内,依次打开对应像素单元被施加第二数据电压信号的栅线行,向被打开的所述栅线行上的像素单元加载第二数据电压信号,第一数据电压信号和第二数据电压信号极性相反,第一数据电压信号的电压极性为正且第二数据电压信号的电压极性为负,或者第一数据电压信号的电压极性为负且第二数据电压信号的电压极性为正;在每一1/X帧的时间内,对于剩余每一栅线组进行与上一栅线组同样的驱动电压极性反转操作,直至在一帧内完成对X个栅线组的驱动电压极性反转操作。
所述液晶面板驱动电压极性反转方法,同一栅线组内的像素单元只需进行一次驱动电压极性反转操作,相对于现有的显示面板的驱动过程中数据电压信号每行或者每两行的极性就会反转的操作,减少了电压极性反转的频率,降低了driver
IC的上升温度,达到了省电的目的。
具体地,对该X个连续的栅线组进行驱动电压极性反转操作时,可以由上至下依次对每个栅线组进行驱动电压极性反转操作,具体流程如图1所示。也可以根据预设顺序依次对每个栅线组进行驱动电压极性反转操作。可选地,在本申请的另一些实施方式中,可不采用将液晶面板栅线由上至下平均分为X个连续的栅线组的方式,而将液晶面板栅线分为栅线行数不同的栅线组,分别对每个栅线组进行驱动电压极性反转操作。
当对于某一栅线组,向被打开的栅线行上的像素单元加载第一数据电压信号后,Tcon IC的行缓冲数据中只存储该栅线组中对应像素单元被施加第二数据电压信号的栅线行的第二数据电压信号,向被打开的栅线行上的像素单元加载第二数据电压信号后,Tcon
IC的行缓冲数据中无存储数据。该Tcon IC的行缓冲数据的存储规则,解决了不论是1line架构、2line架构还是1+2line架构,在显示面板的驱动过程中,如要减少显示面板上数据电压信号的极性反转,则需要在Tcon
IC的行缓冲数据中存储整个显示面板中未加载的数据电压信号,会消耗较多的Tcon IC资源的问题,达到了相对节省Tcon IC资源的效果。需要说明的是,本申请实施例的液晶面板驱动电压极性反转方法在一些具体的实施方式中,Tcon
IC的行缓冲数据根据需要,也可以存储整个显示面板中未加载的数据电压信号。
在本申请实施例中,具体地,设液晶面板的data驱动频率为frame_rate,分辨率为M*N,若将液晶面板栅线由上至下平均分为X个连续的栅线组,X为不小于2的整数,则Tcon IC的linebuffer(行缓冲)数据有N/2X条,gate驱动频率为2X*frame_rate。

以data驱动频率为frame_rate=60HZ,分辨率为3840*2160的液晶面板为例,将液晶面板栅线由上至下平均分为3个连续的栅线组,如图2所示。则Tcon IC的linebuffer(行缓冲)数据有2160/6=360条,gate驱动频率为6*60=360HZ。该面板驱动架构采用1line架构,采用本申请实施例的液晶面板驱动电压极性反转方法,第1个1/6帧至第6个1/6帧的极性示意图如图3(a)至图3(f)所示。
