Description

一种液晶显示面板及液晶显示装置
【技术领域】
本发明涉及液晶显示技术领域,特别是涉及一种亮度补偿的液晶显示面板。
【背景技术】
TFT-LCD(薄膜晶体管液晶显示器),是有源矩阵类型液晶显示器(AM-LCD)中的一种。TFT-LCD作为一种优质平板显示装置,其优点是体积小、功耗低、分辨率高、色彩饱和度高、图像刷新速度快等优点。
TFT-LCD面板可视为两块玻璃基板中间夹着一层液晶,上层的玻璃基板上设置有彩色滤光片、而下层的玻璃板上设置有薄膜晶体管(TFT)。通过TFT上的信号产生电场变化来控制液晶分子的转动方向,改变偏振光的透过率,达到显示目的。此外,上层玻璃与彩色滤光片贴合,形成多个像素单元包含红蓝绿三种颜色,这些发出红蓝绿色彩的像素单元便构成了液晶显示面板上的图像画面。
液晶本身不能发光,它只能通过调节背光源的光场来实现显示,液晶显示面板相对于背光模块来设置,此背光模块可为侧光式(side Lighting)背光模块或直下式入光(Bottom Lighting)背光模块,以提供背光至液晶显示面板背光源发光,使液晶发光。但是在室外及强光环境中,液晶显示装置的亮度和对比度大大降低,为了提高对比度和亮度只有增大背光亮度,而背光亮度越高,功耗越大。
【发明内容】
本发明的一个目的在于提供一种液晶显示面板,以解决在室外及强光环境中,为了提高液晶显示器的亮度和对比度需要增大背光模块的背光亮度,造成功耗较大的技术问题。

所述幅度控制单元通过外界线路连接所述光强调节像素的所述薄膜晶体管的输入端,用于向所述光强调节像素输入光强调节信号,其中所述光强调节信号根据环境光的强度生成。
在本发明的液晶显示面板中,所述光强调节像素还包括一薄膜晶体管,所述调节模块包括幅度控制单元和开启控制单元;
所述薄膜晶体管的输出端与所述光强调节像素的像素电极连接;
所述开启控制单元通过外界线路连接所述光强调节像素的所述薄膜晶体管的控制端,用于控制所述光强调节像素的所述薄膜晶体管的开启关闭;
所述液晶显示面板还包括:
源驱动芯片,用于向所述数据线传输数据信号;
所述幅度控制单元设置在源驱动芯片中,通过所述数据线连接所述光强调节像素的所述薄膜晶体管的输入端,用于向所述薄膜晶体管输入光强调节信号,其中所述光强调节信号根据环境光的强度生成。
在本发明的液晶显示面板中,所述光强调节像素的光强调节信号是根据相应的所述显示像素的图像信号以及所述环境光的强度生成。
在本发明的液晶显示面板中,所述光强调节像素的光强调节信号为相应的所述显示像素的所有子像素的图像信号的均值乘以增益系数,所述增益系数与所述环境光的强度成正比。
在本发明的液晶显示面板中,所有所述光强调节像素的所述薄膜晶体管的控制端共用一驱动信号,所述驱动信号为直流低电位电压。
在本发明的液晶显示面板中,所述显示像素包括红、绿、蓝子像素,所述光调节像素为白色像素。

背光模块,以及
液晶显示面板,所述液晶显示面板包括第一基板和第二基板、以及设置于所述第一基板和所述第二基板之间的液晶层;
所述第二基板包括数据线、扫描线以及由所述数据线和所述扫描线交错形成的多个像素单元;
其中所述像素单元包括:
显示像素,用于显示图像信号;以及
光强调节像素,用于通过改变自身的显示亮度来调节所述液晶显示面板的亮度。
本发明通过增加一可以改变自身的显示亮度的光强调节像素,所述光强调节像素的显示亮度可以根据环境光的强度调节,在室外或者强光环境中,不用增大背光模块的背光亮度,也能够提高液晶显示面板的对比度和亮度,从而降低了功耗。

图1是现有技术中液晶显示面板的结构示意图。
图2是本发明实施例中第一实施例的液晶显示面板结构示意图。
图3是本发明实施例中第二实施例的液晶显示面板结构示意图。
【具体实施方式】
以下各实施例的说明是参考附加的图式,用以例示本发明可用以实施的特定实施例。本发明所提到的方向用语,例如「上」、「下」、「前」、「后」、「左」、「右」、「内」、「外」、「侧面」等,仅是参考附加图式的方向。因此,使用的方向用语是用以说明及理解本发明,而非用以限制本发明。在图中,结构相似的单元是以相同标号表示。
请参照图1,图1为现有技术中液晶显示面板的结构示意图。
液晶显示装置可包括液晶显示面板100和背光模块(未绘示)。液晶显示面板100相对于背光模块来设置,此背光模块可为侧光式(side Lighting)背光模块或直下式入光(Bottom Lighting)背光模块,以提供背光至液晶显示面板100。背光模块的亮度是可调整的,液晶显示面板100具有多个显示像素(譬如红R、绿G、蓝B),这些显示像素的亮度随灰阶值增大而提高,灰阶值0~N,N例如是255,灰阶值为255时,液晶显示面板100的亮度最高。
如图1所示,液晶显示面板100可包括第一基板110、第二基板120、液晶层130、第一偏光片140、第二偏光片150及相位延迟差片160。液晶层130是形成于第一基板110及第二基板120之间,即液晶层130是位于第一基板110及第二基板120的内侧。第一偏光片140是设置于第一基板110的外侧,第二偏光片150是设置于第二基板120的外侧,相位延迟差片160可贴合于第一基板110或第二基板120的外侧表面上。
如图1所示,第一基板110和第二基板120的基板材料可为玻璃基板或可挠性塑料基板,第一基板110可例如为具有彩色滤光片(Color Filter,CF)的玻璃基板或其它材质的基板,而第二基板120可例如为具有薄膜晶体管(Thin Film Transistor,TFT)矩阵的玻璃基板或其它材质的基板。值得注意的是,在一些实施例中,彩色滤光片和TFT矩阵亦可配置在同一基板上。
第二基板120还包括数据线、扫描线、由所述数据线和所述扫描线形成多个像素单元,所述像素单元包括:显示像素包括多个子像素(譬如R、G、B),用于显示图像信号,每个显示像素的所有子像素都包括一薄膜晶体管。
第二基板120还包括栅驱动芯片,通过所述扫描线连接所述显示像素的薄膜晶体管的控制端,通过所述扫描线向所述显示像素输入扫描信号,控制所述薄膜晶体管的开启关闭;以及源驱动芯片,其通过所述数据线连接所述显示像素的薄膜晶体管的输入端,在薄膜晶体管导通时,通过所述数据线向所述显示像素输入数据信号,以生成图像。
第二基板120设置有像素电极,该像素电极通过薄膜晶体管输入端的数据信号在薄膜晶体管输出端产生一像素电压,即显示像素的所有子像素R、G、B内的像素电极分别产生一像素电压,该像素电压与所有子像素对应第一基板110中第一电极(图未标示)的公共电压Vcom之间产生电压差,形成电场,该电场驱动液晶层130内的液晶分子发生倾斜,进而使得光线透过或者不透过液晶层130,使液晶显示面板100形成不同的亮度。
请参照图2,图2是本发明实施例中第一实施例的液晶显示面板结构示意图。
如图2所示,第二基板120包括多个像素单元,所述像素单元包括:显示像素(RGB),所述像素单元还包括光强调节像素(白色像素W),白色像素能够通过改变自身的显示亮度来调节所述液晶显示面板的亮度,每个所述光强调节像素包括一薄膜晶体管。
本实施例中在栅驱动芯片23通过所述扫描线(G1-G4)输入的扫描信号为高电平时,源驱动芯片22通过所述数据线(D1-D6)向所述显示像素的所有子像素(譬如RGB)输入的数据信号为图像信号,以生成彩色图像;
所述液晶显示面板100还包括调节模块21,所述调节模块21外接于所述液晶显示面板100,能够根据环境光的强度调节所述光强调节像素的显示亮度。所述光强调节像素自身的显示亮度是通过光强调节信号来改变的,其中光强调节信号根据环境光的强度生成。
所述调节模块21包括开启控制单元211和幅度控制单元212,所述光强调节像素的薄膜晶体管的输出端连接所述光强调节像素的像素电极;该像素电极通过薄膜晶体管输入端的光强调节信号在该薄膜晶体管输出端产生一像素电压。
所述开启控制单元211通过外界线路连接所述光强调节像素的所述薄膜晶体管的控制端,通过外界线路输入一驱动信号来控制所述光强调节像素的薄膜晶体管的开启关闭。优选地,所有所述光强调节像素的所述薄膜晶体管的控制端共用一驱动信号,所述驱动信号为直流低电位电压,电压的高低相对于第一基板上第一电极的公共电压(Vcom)作参照。
所述幅度控制单元212通过外界线路连接所述光强调节像素的所述薄膜晶体管的输入端,在所述薄膜晶体管开启时,所述幅度控制单元212向所述光强调节像素输入光强调节信号,其中所述光强调节信号根据环境光的强度生成,譬如所述光强调节信号的电压等于增益系数乘以所述显示像素的所有子像素的图像信号电压的均值(也可以是方差等)生成,其中所述增益系数与环境光的强度成正比。当环境光强的时候,所述增益系数越大,输入所述光强调节像素的光强调节信号的电压越大,当所述环境光弱的时候,所述增益系数越小,输入所述光强调节像素的光强调节信号的电压越小。所述光强调节信号譬如为一方波信号,该方波信号的周期为画面帧的周期,该方波信号的电压可根据人眼对环境光强弱的感受进行人工调节或者由幅度控制单元212根据环境光的强度自动控制,从而将调节后的方波信号输入,方波信号的电压高低相对于Vcom的电压值作参照。
当幅度控制单元212根据环境光的强度自动控制时,幅度控制单元212譬如还包括环境光监测器,根据环境光监测器监测到的环境光的强度自动调整所述光强调节信号的电压幅度,当监测到环境光强的时候,幅度控制单元212增大光强调节信号的电压值,使光强调节像素的薄膜晶体管输出端的像素电压变高,从而使液晶显示面板的亮度越高;当所述环境光弱的时候,幅度控制单元212降低光强调节信号的电压值,使光强调节像素的薄膜晶体管输出端的像素电压降低,从而使液晶显示面板的亮度变暗。
通过调整输入到所述光强调节像素的光强调节信号的电压,改变光强调节像素的像素电压与相应第一基板上第一电极的公共电压的电压差值,改变光线的透过率,从而调整液晶显示器的亮度。
譬如,所述光强调节信号通过改变白色像素的像素电压与该像素对应第一基板110中第一电极的公共电压之间形成电压差,其中白色像素的像素电压是由白色像素的薄膜晶体管输入端输入的光强调节信号在白色像素的薄膜晶体管的输出端产生的,该电压差使白色像素形成不同的灰阶,从而可以改变白色像素自身的显示亮度。通常情况下,第一基板110中第一电极的公共电压保持不变,因而只需要改变输入到白色像素的像素电压就可以改变所述电压差。当输入到白色像素的光强调节信号越大,所述电压差越大,白光的透过率越高,液晶显示面板的亮度越高,当输入到白色像素的光强调节信号越小,所述电压差越小,白光的透过率越低,液晶显示面板的亮度越暗。
本发明通过增加光强调节像素(白色像素),并且根据环境光的强度自适应地调节输入到白色像素的光强调节信号的电压,从而调节白光的透过率,因此在室外或者强光环境下,不需要增大背光源的背光亮度,就能提高液晶显示面板的亮度。
请参照图3,图3是本发明实施例中第二实施例的液晶显示面板结构示意图。
第二基板120包括多个像素单元,所述像素单元包括:显示像素(RGB),所述像素单元还包括光强调节像素(白色像素W),白色像素能够通过调节自身的亮度来调节液晶显示面板的亮度,所述光强调节像素包括一薄膜晶体管,本实施例中在栅驱动芯片33输入的扫描信号为高电平时,源驱动芯片32通过所述数据线输入的数据信号包括图像信号和光强调节信号;即源驱动芯片32通过所述数据线向所述显示像素的所有子像素(譬如RGB)传输图像信号,以生成彩色图像;向所述光强调节像素传输光调节信号。
所述液晶显示面板100还包括调节模块(图中未绘出),所述调节模块能够根据环境光的强度调节所述光强调节像素的显示亮度,通过光强调节信号改变所述光强调节像素自身的亮度,其中光强调节信号根据环境光的强度生成。所述调节模块包括开启控制单元311和幅度控制单元312;
所述光强调节像素的薄膜晶体管的输出端与所述光强调节像素的像素电极连接;该像素电极通过薄膜晶体管输入端的光强调节信号在该薄膜晶体管输出端产生一像素电压。
所述开启控制单元311通过外界线路连接所述光强调节像素的所述薄膜晶体管的控制端,通过外界线路输入一驱动信号来控制所述光强调节像素的薄膜晶体管的开启关闭。优选地,所有所述光强调节像素的所述薄膜晶体管的控制端共用一驱动信号,所述驱动信号为直流低电位电压;电压的高低相对于第一基板上第一电极的公共电压(Vcom)作参照。所述幅度控制单元312设置在数据驱动芯32片中,通过数据线连接(譬如D4、D8)所述光强调节像素的所述薄膜晶体管的输入端,在所述薄膜晶体管开启时,向所述薄膜晶体管的输入光强调节信号,其中所述光强调节像素的光强调节信号是根据相应的所述显示像素的图像信号以及所述环境光的强度生成,譬如所述光强调节信号的电压等于增益系数乘以所述显示像素的所有子像素的图像信号电压的均值(也可以是方差等)生成,其中所述增益系数与环境光的强度成正比。当环境光强的时候,所述增益系数越大,输入所述光强调节像素的光强调节信号的电压越大,当所述环境光弱的时候,所述增益系数越小,输入所述光强调节像素的光强调节信号的电压越小。所述光强调节信号譬如为一方波信号,该方波信号的周期为画面帧的周期,该方波信号的电压由幅度控制单元312根据环境光的强度自动控制,从而将调节后的方波信号输入,方波信号的电压高低相对于Vcom的电压值作参照。
通过调整输入到所述光强调节像素的光强调节信号的电压,改变光强调节像素的像素电压与相应第一基板上第一电极的公共电压的电压差值,改变光线的透过率,从而调整液晶显示器的亮度。
譬如,所述光强调节信号通过改变白色像素的像素电压与该白色像素对应第一基板110中第一电极的公共电压之间形成电压差,其中白色像素的像素电压是由白色像素的薄膜晶体管输入端输入的光强调节信号在该薄膜晶体管的输出端产生的,该电压差使白色像素形成不同的灰阶,从而可以改变自身的显示亮度。通常情况下,第一基板110中第一电极的公共电压保持不变,因而只需要改变输入到白色像素的像素电压就可以改变所述电压差。当输入到白色像素的光强调节信号越大,所述电压差越大,白光的透过率越高,液晶显示面板的亮度越高,当输入到白色像素的光强调节信号越小,所述电压差越小,白光的透过率越低,液晶显示面板的亮度越暗。
本发明通过增加光强调节像素(白色像素),并且根据环境光的强度自适应地调节输入到白色像素的光强调节信号的电压,从而调节白光的透过率,因此在室外或者强光环境下,不需要增大背光源的背光亮度,就能提高液晶显示面板的亮度。相对于本发明的第一实施例,本实施例由于所述调节模块内置于所述液晶控制面板中,因而具有集成度高,降低生产成本的有益效果。
