Description

一种色偏补偿方法 【技术领域】
本发明涉及驱动电路技术领域,特别涉及一种色偏补偿方法。
【背景技术】
现有技术的液晶显示器中为解决残影现象,通常使用过电压驱动(Over Driver,OD)技术。液晶分子每一种稳定的状态都对应着一定的电压,当在电极上加电压时,液晶分子不是即时转动到目标状态,而是在一定的响应时间之后才能达到这个状态,电压越高,分子转动的速度越快。传统的液晶显示器中,在液晶分子上施加的驱动电压就是目标状态的对应电压,由于不同灰阶的对应电压不同,分子需要转过的角度也不同,这就造成了不同灰阶转换的响应时间千差万别。而在采用过电压驱动技术的液晶显示器中,施加的驱动电压在起始的时候稍高于目标状态的对应电压,使得液晶分子转动的速度更快,在到达目标状态时,电压再回落至目标状态的对应电压以保持状态,这样就有效缩短了反应时间,而且使不同灰阶切换的响应时间平均化。
薄膜晶体管液晶显示器中的三栅极机种为节省功耗,均采用翻转像素结合行反转的驱动方式。但因三栅极机种本身的像素电极充电时间很短,很容易出现像素电极充电不足的现象。当前景与背景颜色差异比较大时,前景的边缘处部分像素电极就会因充电不足而导致出现锯齿现象,使字体变得粗糙影响显示品位。另 外,对于比较特殊的画面来说,比如像素交错亮暗的画面或者相邻两个像素交错亮暗的画面,对三栅极液晶显示面板进行色偏补偿,会使画面出现噪点,使得色偏补偿效果适得其反。上述技术问题影响了液晶显示面板的显示效果,亟待解决。
【发明内容】
本发明的目的在于提供一种色片补偿方法,已解决现有技术中,因三栅极机种本身的像素电极充电时间很短,很容易出现像素电极充电不足的现象,使得当前景与背景颜色差异比较大时,会导致前景的边缘处部分像素电极就会因充电不足而导致出现锯齿现象,使字体变得粗糙影响显示品位,并且对于像素交错亮暗的画面或者相邻两个像素交错亮暗的画面,对三栅极液晶显示面板进行色偏补偿,会使画面出现噪点,使得色偏补偿效果适得其反的问题。

将所述第一灰阶值存储在所述第一像素电极对应的行数据缓存器内,以作为下一行的第三像素电极的上一行灰阶值数据,所述第三像素电极与所述第一像素电极共用一列数据线。
优选地,其中获取当前待充电的第一像素电极的第一行列位置及所述第一像素电极画面的第一灰阶值,之前还包括:
确定第一行第一列的初始像素电极所连接的数据线与其的相对位置,以确定所述液晶显示面板的排列架构。
优选地,其中所述第二像素电极在所述液晶显示面板的所述第二行列位置,根据所述第一行列位置与所述液晶显示面板的排 列架构得到。
优选地,其中若所述第一像素电极位于所述三栅极液晶显示面板的第一行,则判定所述第二灰阶值为0。
优选地,其中根据所述第一灰阶值与所述第二灰阶值得出所述第一像素电极的目标充电电压,并按照所述目标充电电压对其进行充电,或用与所述第一灰阶值对应的充电电压对其进行充电,之前还包括:

实施例二
请参考图2,图2为本实施例的一种色偏补偿方法另一实施 流程图,从图2可以看到,本发明的一种色偏补偿方法,用于三栅极液晶显示面板,所述三栅极液晶显示面板包括多行栅极线及多列数据线,包括以下步骤:
步骤S201:获取当前待充电的第一像素电极的第一行列位置及所述第一像素电极画面的第一灰阶值。
在本实施例中,获取当前待充电的第一像素电极的第一行列位置及所述第一像素电极画面的第一灰阶值,之前还包括:

查询表格
步骤S204:根据所述补偿灰阶值得到所述第一像素电极对应的充电电压,以作为所述目标充电电压,所述目标充电电压可使所述第一像素电极的画面亮度达到所述第一灰阶值对应的亮度。
在本步骤中,若所述补偿灰阶值为0,则将与所述第一灰阶值对应的充电电压作为第一像素电极的充电电压,此时所述第一灰阶值对应的充电电压和所述目标充电电压大小相同。此时与所述第一灰阶值对应的充电电压,也可使所述第一像素电极的画面亮度达到所述第一灰阶值对应的亮度。
步骤S205:按顺序获取N个所述第一像素电极所在行的像素电极的灰阶值,其中N为大于或等于8的偶数,并按顺序将N个灰阶值中相邻的两个作为一组,将每组内的偶数列的灰阶值与 奇数列的灰阶值相减求差值,得到N/2个第一灰阶值差值S1~SN/2
步骤S206:按顺序将N/2个第一灰阶差值中相邻的两个作为一组,将每组内的偶数列的灰阶值与奇数列的灰阶值相减求差值,得到N/4个第二灰阶值差值E1~EN/4

如图3和图4所示,图3为本发明实施例的三栅极液晶显示面板的像素交错亮暗的画面,图4为本发明实施例的三栅极液晶显示面板的相邻两个像素交错亮暗的画面。当液晶显示面板出现图3和图4的画面时,如果继续对像素电极进行色偏补偿的话,会导致画面更加模糊,副作用更大。因此,在液晶显示面板出现像素交错亮暗的画面,或出现相邻两个像素交错亮暗的画面时,必须停止对像素电极进行色偏补偿,而要按照该像素电极对应的灰阶值的充电电压对其进行充电。
在本实施例中,步骤S207中的确定用所述目标充电电压对所述第一像素电极进行充电,或用与所述第一灰阶值对应的充电电压对所述第一像素电极进行充电,具体包括:
若所述N/4个第二灰阶值差值E1~EN/4均等于0,则用与所述第一灰阶值对应的充电电压对所述第一像素电极进行充电。此时,根据图3和图4的画面,可以推断出这时液晶显示面板的画面为像素交错亮暗的画面,或为相邻两个像素交错亮暗的画面,因此必须停止对所述第一像素电极进行色偏补偿,即不能对其使用所述目标充电电压进行充电,而应该用与所述第一灰阶值对应的充电电压对所述第一像素电极进行充电。
在本实施例中,确定用所述目标充电电压对所述第一像素电极进行充电,或用与所述第一灰阶值对应的充电电压对所述第一像素电极进行充电,具体还包括:
若所述N/4个第二灰阶值差值E1~EN/4均小于所述第一灰阶值阈值,则判断所述N/2个第一灰阶差值S1~SN/2是否均大于所述第二灰阶值阈值。
若所述N/2个第一灰阶差值S1~SN/2不是都大于所述第二灰阶值阈值,则根据图3和图4可以推断出,此时液晶显示面板的画面不是像素交错亮暗的画面,或相邻两个像素交错亮暗的画面,则此时亦可以使用所述目标充电电压对所述第一像素电极进行充电,进行色偏补偿。
在本实施例中,判断所述N/2个第一灰阶差值S1~SN/2是否均大于所述第二灰阶值阈值,同时还包括:
若所述N/2个第一灰阶差值S1~SN/2均大于所述第二灰阶值 阈值,则进一步获取当前行前两个像素电极的灰阶值与它们对应的上一行的行数据存储器的灰阶值的差值,并判断两个所述差值是否均等于所述第一灰阶差值S1
若两个所述差值均等于所述第一灰阶差值S1,则根据图3和图4可以判定此时液晶显示面板的画面是像素交错亮暗的画面,或相邻两个像素交错亮暗的画面,则用所述第一灰阶值对应的充电电压对所述第一像素电极进行充电,否则用所述目标充电电压对所述第一像素电极进行充电。
步骤S208:将所述第一灰阶值存储在所述第一像素电极对应的行数据缓存器内,以作为下一行的第三像素电极的上一行灰阶值数据,所述第三像素电极与所述第一像素电极共用一列数据线。
本发明的一种色片补偿方法,通过获取当前待充电的第一像素电极的第一灰阶值,以及与第一像素电极共用一列数据线的第二像素电极的第二灰阶值,并根据第一灰阶值与第二灰阶值得出第一像素电极的目标充电电压,并按照所述目标充电电压对其进行充电,所述目标充电电压可使所述第一像素电极的画面亮度达到所述第一灰阶值对应的亮度,解决了现有技术中,因三栅极机种本身的像素电极充电时间很短,很容易出现像素电极充电不足的现象,使得当前景与背景颜色差异比较大时,会导致前景的边缘处部分像素电极就会因充电不足而导致出现锯齿现象,使字体变得粗糙影响显示品位,并且对于像素交错亮暗的画面或者相邻 两个像素交错亮暗的画面,对三栅极液晶显示面板进行色偏补偿,会使画面出现噪点,使得色偏补偿效果适得其反的问题。
综上所述,虽然本发明已以优选实施例揭露如上,但上述优选实施例并非用以限制本发明,本领域的普通技术人员,在不脱离本发明的精神和范围内,均可作各种更动与润饰,因此本发明的保护范围以权利要求界定的范围为准。
