Definitions
- the present invention relates to the field of liquid crystal display technologies, and in particular, to a liquid crystal display panel and a liquid crystal display.

- TFT Thin Film Transistor
- the amount of chromaticity in the light emitted from the liquid crystal display depends on the backlight spectrum of the backlight 11 and the formulation of the color resistance in the color resist layer 152. Therefore, if the chromaticity is to be increased, the number of pigments in the color resist layer 151 can be increased. Increasing the amount of the pigment in the color resist layer 151 can be achieved by increasing the film thickness or by changing the formulation of the color resist in the color resist layer 151.
- the chromaticity is increased by increasing the film thickness, for example, referring to FIG. 2, since the thickness of the color resist layer 152 is increased, although the surface layer cross-connection of the color resist layer 152 is completed, in actual operation, the color resist layer 152 is The underlying cross-linking is insufficient, and an under-cut phenomenon occurs after the development reaction, which causes the common electrode 153 (ITO) of the CF substrate 15 to be broken, thereby causing display abnormality. In addition, the amount of the pigment in the color resist layer 152 affects the final contrast. Once the film thickness of the color resist layer 152 is increased, the number of collisions between the polarized light and the pigment particles increases, and the polarization of the polarized light becomes non-polarized light, resulting in a decrease in contrast. .
- the chromaticity is increased by changing the formulation of the color resist in the color resist layer 151, for example, the ratio of the pigment in the color resist is increased, the ratio of the polymer/monomer in the color resist layer 152 may be caused. When it is lowered, the characteristics of exposure and development of the color resist layer 152 cannot be achieved, and the process cannot be achieved.

Abstract
一种液晶显示面板及液晶显示器,液晶显示面板包括彩膜片(26,36);液晶显示面板的第二基板(24,34)包括多个像素单元;液晶显示面板的色阻区(222,342,R,G,B)对应一像素单元的像素区(R,G,B);第一基板(22,32)和第二基板(24,34)之间设置液晶层(23,33);彩膜片(26,36)包括多个彩膜区(262,362,R,G,B),分别对应于色阻区(222,342,R,G,B),且相互对应的彩膜区(262,362,R,G,B)和色阻区(222,342,R,G,B)的颜色相同,从而提高液晶显示面板中图像显色色度。
Description
本发明涉及液晶显示技术领域,特别是涉及一种液晶显示面板和液晶显示器。
请参阅图1,图1为现有技术中液晶显示器的结构示意图。
所述液晶显示器包括背光源11、上偏光片12、薄膜晶体管(Thin Film
Transistor,TFT)基板13、液晶层(cell)14、彩色滤光片(Color Filter,CF)基板15以及下偏光片16。
从液晶显示器出射的光线中色度的大小取决于背光源11的背光频谱以及色阻层152中色阻的配方。因此若要提高色度,可以增加色阻层151中色素(pigment)的数量。而要增加色阻层151中色素的数量,可以通过增加膜厚的方式,或者通过改变色阻层151中色阻的配方来实现。
若通过增加膜厚的方式来提高色度,譬如请参阅图2,由于色阻层152的厚度增加,虽然色阻层152的表层交连完成,但是在实际操作过程中,色阻层152的底层交连不足,于显影反应后,会产生底切(under-cut)的现象,进而导致CF基板15的公共电极153(ITO)出现断开的现象,进而造成显示异常。此外,色阻层152中色素的数量会影响到最终对比度,一旦色阻层152的膜厚增加,偏极化光线与色素粒子碰撞次数增加,使偏极光线成为非偏极化光线导致对比度降低。
若通过改变色阻层151中色阻的配方来提高色度,譬如即将色阻中色素的比例提高,则可能会造成色阻层152中聚合物(polymer)/单体(monomer)等比例的下降,导致色阻层152曝光显影的特性将无法达成,制程无法达到。

在该第二较佳实施例中,所述彩膜片36仍是设置于所述第一基板32的外侧。彩膜片36包括玻璃基板361和多个彩膜区362,该彩膜区362具有不同的颜色,譬如R、G、B。在本实施例中,同一颜色的彩膜区362对应相同颜色的色阻区342。譬如彩膜区R对应色阻区R,彩膜区G对应色阻区G,彩膜区B对应色阻区B。
图4所示的第二较佳实施例与图3所示的第一较佳实施例的原理类似,此处不再详述。
图5为本发明中液晶显示面板的第三较佳实施例的结构示意图。
在该第三较佳实施例中,液晶显示面板包括第一偏光片31、第一基板32、液晶层33、第二基板34、第二偏光片35以及彩膜片36。其中,液晶层33是形成于第一基板32及第二基板34之间,亦即液晶层33是位于第一基板32及第二基板34的内侧。第一偏光片31是设置于第一基板32的外侧,第二偏光片35是设置于第二基板34的外侧。
与图4所示的第二较佳实施例不同之处在于,该第三较佳实施例中,所述彩膜片36是设置于所述第一基板32的内侧。彩膜片36包括玻璃基板361和多个彩膜区362,该彩膜区362具有不同的颜色,譬如R、G、B。在本实施例中,同一颜色的彩膜区362对应相同颜色的色阻区342。譬如彩膜区R对应色阻区R,彩膜区G对应色阻区G,彩膜区B对应色阻区B。
图5所示的第三较佳实施例与图4所示的第二较佳实施例原理类似,此处不再赘述。
本发明还提供一种液晶显示器,包括背光模组,还包括本发明提供的液晶显示面板,鉴于该液晶显示面板在上文已有详细的描述,此处不再赘述。
本发明相对现有技术,通过在液晶显示面板上设置一彩膜片,尤其是将该彩膜片设置在液晶显示面板的出光侧,该彩膜片包括多个颜色的彩膜区,相同颜色的彩膜区对应相同颜色的色阻区,从液晶显示面板出射的光线经所述彩膜片的色彩加强后,极大的提高了影像的显色色域。
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。
