说 明 书 液晶显示器及其液晶面板 技术领域
本发明涉及显示领域, 具体地讲, 涉及一种液晶显示器及其液晶面板。 背景技术 与等离子显示器 (Plasma Panel Display, PDP)、 有机发光二极管(Organic Light Emitting Diode, OLED )显示器、 阴极射线管( Cathode Ray Tube, CRT) 显示器等可自发光不同, 液晶显示器(Liquid Crystal Display, LCD)是非自发 光的显示器。 目前, 液晶显示器所采用的光源可分为电激发光 (Electroluminescence , EL)、发光二极管(Light Emitting Diode, LED)与冷阴极荧光灯(Cole Cathode Florescent Lamp, CCFL) , 其中, 以 LED应用较为广泛。 白光 LED作为液晶 显示器的光源, 具有省电、 体积小等优点, 目前已广泛适用于移动电话、 个人 数字助理 (Personal Digital Assistant, PDA), 数字相机和笔记本电脑等小型液 晶显示器中。 图 1是根据现有技术的液晶显示器的剖视示意图。 如图 1所示, 背光模块 11包括: LED111、 反射片 112、 导光板 113及光学膜片等组件, LED111所 发射的光可经由这些组件而向上传到透明玻璃基板 12。 透明玻璃基板 12上设 置有多个薄膜晶体管 (Thin Film Transistor, TFT ) 121 , 经由薄膜晶体管 121 的控制, LED111所发射的光光即可穿过液晶层 13到达另一透明玻璃基板 14 上的彩色滤光片 (Color Filter) 141。 LED111所发射的光经过彩色滤光片 141 上红色 (R) 子像素 (Sub-pixel)、 绿色 (G) 子像素或蓝色 (B ) 子像素的即 会呈现红色 (R)、 绿色 (G) 或蓝色 (B ) , 最后显示在液晶显示器的面板上。 然而, 随着人们对液晶显示器的色彩的要求越来越高, 已经提出了多种高 色饱和度的方案, 例如, 直接采用白光 LED、 组合不同颜色光的 LED形成白 光、 采用单一颜色光的 LED搭配荧光粉层等。 但是, 在上述这些方案中, 由 于透明玻璃基板 14上的彩色滤光片 141的透射频谱中存在透射波峰, 而 LED111所发射的光具有一定的波峰宽度, 如果需要提升液晶显示器的色彩显 示范围,则需要增加 LED111所发生的光中长波段光的比例(例如红光、绿光), 这样会使 LED111的效率下降, 进而降低了 LCD的效率, 最直接表现在于降 低了光的利用率。 发明内容

附图说明 通过结合附图, 从下面的描述中, 本公开的上述和其他方面、 特点和其他 优点将会更清楚地被理解, 附图中: 图 1是根据现有技术的液晶显示器的剖视示意图; 图 2是根据本发明的第一实施例的液晶显示器的剖视示意图; 图 3是根据本发明的第二实施例的液晶显示器的剖视示意图; 图 4是根据本发明的第三实施例的液晶显示器的剖视示意图; 图 5是根据本发明的第四实施例的液晶显示器的剖视示意图; 图 6是根据本发明的第五实施例的液晶显示器的剖视示意图; 图 7是根据本发明的第六实施例的液晶显示器的剖视示意图; 图 8是根据本发明的第七实施例的液晶显示器的剖视示意图; 图 9是根据本发明的第八实施例的液晶显示器的剖视示意图; 图 10是本发明的一种直下式背光模块的剖视示意图。 具体实施方式 以下, 将参照附图来详细描述本发明的实施例。 附图中, 相同的标号将始 终被用于表示相同的元件。 图 2是根据本发明的第一实施例的液晶显示器的剖视示意图。 参照图 2, 根据本发明的第一实施例的液晶显示器包括背光模块 21、 第一 基板 22、 液晶层 23和第二基板 24。 其中, 第一基板 22和第二基板 24可由透 明材料 (例如玻璃) 形成。 具体而言, 背光模块 21包括: 蓝光 LED211、 反射片 212、 导光板 213及 光学膜片、 固定件等组件。 LED211所发射的蓝光可经由这些组件而向上传到 第一基板 22。第一基板 22上设置有多个薄膜晶体管(Thin Film Transistor, TFT) 221 , 经由薄膜晶体管 221的控制, 蓝光穿过第一基板 22上的荧光粉层 222和 液晶层 23到达第二基板 24上的彩色滤光片 (Color Filter) 241。 在本实施例中, 彩色滤光片 241包括多个阵列排布的像素 2411, 而各个像 素 2411之间具有间隙 2412。与现有技术不同的是,每个像素 2411包括红色 (R) 子像素 (Sub-pixel) 和绿色 (G) 子像素, 其中, 每个子像素是由与其颜色对 应的光阻沉积在第二基板 24上形成的。 换句话说, 将现有技术的像素中的蓝 色 (B ) 子像素去除形成间隙 2412。 相对应地, 将与彩色滤光片 241上的间隙 2412相对应的荧光粉层去除, 也就是说, 第一基板 22上的与彩色滤光片 241 上的红色子像素、 绿色子像素对应处设置荧光粉层 222。 荧光粉层 222可为黄色荧光粉层 YF。 蓝光穿过荧光粉层 222后, 由于蓝 光为短波长的光,所以可激发荧光粉层 222内的荧光微粒,经混光后发出白光。 当白光经过彩色滤光片 241上的红色子像素和绿色子像素后分别呈现红色和绿 色, 最后显示在液晶显示器的面板上。 而穿过荧光粉层 222中被去除了荧光粉 层位置处的蓝光穿过液晶层 23到达彩色滤光片 241,并从彩色滤光片上的间隙 2412直接穿过, 呈现蓝色, 最后显示在液晶显示器的面板上。 在本实施例中, 蓝光 LED可替换为蓝紫光 LED、 紫光 LED、 紫外光 LED 等的短波长 LED。 此外, 为了在液晶显示器的面板上呈现的红色、 绿色和蓝色 能够混色形成白色, 由于黄色荧光粉层 YF会对穿过其内部的蓝光进行吸收, 所以本实施例优选地使红色子像素的尺寸与绿色子像素的尺寸相等, 而使间隙 2412的尺寸小于它们二者中任一个的尺寸。具体地说, 红色子像素的宽度与绿 色子像素的宽度相等, 而间隙 2412的宽度小于红色子像素的宽度或绿色子像 素的宽度。 根据本实施例的液晶显示器, 由于蓝光 LED所发射的蓝光中的一部分直 接穿过液晶层 23, 并通过间隙 2412后显示在液晶显示器的面板上, 减少了荧 光粉层 222及形成蓝色子像素的光阻对其的吸收, 所以提高了光的利用率,进 而提高液晶显示器的整体效率。 图 3是根据本发明的第二实施例的液晶显示器的剖视示意图。 在本实施例的描述中, 与第一实施例相同之处在此不再赘述, 仅描述与第 一实施例不同之处。 参照图 3,与第一实施例不同之处在于,第一基板 22上设置有多个薄膜晶 体管(Thin Film Transistor, TFT )221,经由薄膜晶体管 221的控制,蓝光 LED211 所发射的蓝光液晶层 23和第二基板 24上的荧光粉层 222之后, 到达第二基板 24上的彩色滤光片 (Color Filter) 241。 也就是说, 在本实施例中, 将荧光粉 层 222设置在第二基板 24之上, 即彩色滤光片 241与液晶层 23之间。 图 4是根据本发明的第三实施例的液晶显示器的剖视示意图。 在本实施例的描述中, 与第一实施例相同之处在此不再赘述, 仅描述与第 一实施例不同之处。 参照图 4, 与第一实施例不同之处在于, 在彩色滤光片 241上的间隙 2412 处设置蓝色 (B ) 子像素。 即在本实施例中, 每个像素 2411包括红色 (R) 子 像素 (Sub-pixel)、 绿色 (G) 子像素和蓝色 (B ) 子像素。 此外, 为了在液晶 显示器的面板上呈现的红色、 绿色和蓝色能够混色形成白色, 由于黄色荧光粉 层 YF会对穿过其内部的蓝光进行吸收, 所以本实施例优选地使红色子像素的 尺寸与绿色子像素的尺寸相等, 而使蓝色子像素的尺寸小于它们二者中任一个 的尺寸。 具体地说, 红色子像素的宽度与绿色子像素的宽度相等, 而蓝色子像 素的宽度小于红色子像素的宽度或绿色子像素的宽度。 根据本实施例的液晶显示器, 由于蓝光 LED所发射的蓝光中的一部分穿 过液晶层 23, 并通过间隙 2412处设置的蓝色子像素后显示在液晶显示器的面 板上, 减少了荧光粉层 222对其的吸收, 所以提高了光的利用率, 进而提高液 晶显示器的整体效率。 图 5是根据本发明的第四实施例的液晶显示器的剖视示意图。 在本实施例的描述中, 与第一实施例相同之处在此不再赘述, 仅描述与第 一实施例不同之处。 参照图 5,与第一实施例不同之处在于,第一基板 22上设置有多个薄膜晶 体管(Thin Film Transistor, TFT )221,经由薄膜晶体管 221的控制,蓝光 LED211 所发射的蓝光液晶层 23和第二基板 24上的荧光粉层 222之后, 到达第二基板 24上的彩色滤光片 (Color Filter) 241。 也就是说, 在本实施例中, 将荧光粉 层 222设置在第二基板 24之上, 即彩色滤光片 241与液晶层 23之间。 另外, 在彩色滤光片 241上的间隙 2412处设置蓝色(B )子像素。 即在本 实施例中, 每个像素 2411包括红色 (R)子像素(Sub-pixel)、 绿色 (G)子像 素和蓝色 (B ) 子像素。 为了在液晶显示器的面板上呈现的红色、 绿色和蓝色 能够混色形成白色, 由于黄色荧光粉层 YF会对穿过其内部的蓝光进行吸收, 所以本实施例优选地使红色子像素的尺寸与绿色子像素的尺寸相等, 而使蓝色 子像素的尺寸小于它们二者中任一个的尺寸。 具体地说, 红色子像素的宽度与 绿色子像素的宽度相等, 而蓝色子像素的宽度小于红色子像素的宽度或绿色子 像素的宽度。 根据本实施例的液晶显示器, 由于蓝光 LED所发射的蓝光中的一部分穿 过液晶层 23, 并通过间隙 2412处设置的蓝色子像素后显示在液晶显示器的面 板上, 减少了荧光粉层 222对其的吸收, 所以提高了光的利用率, 进而提高液
图 6是根据本发明的第五实施例的液晶显示器的剖视示意图。 参照图 6, 根据本发明的第五实施例的液晶显示器包括背光模块 21、 第一 基板 22、 液晶层 23和第二基板 24。 其中, 第一基板 22和第二基板 24可由透 明材料 (例如玻璃) 形成。 具体而言, 背光模块 21包括: 蓝光 LED211、 反射片 212、 导光板 213及 光学膜片、 固定件等组件。 LED211所发射的蓝光可经由这些组件而向上传到 第一基板 22。第一基板 22上设置有多个薄膜晶体管(Thin Film Transistor, TFT) 221 , 经由薄膜晶体管 221的控制, 蓝光穿过第一基板 22上的荧光粉层 422和 液晶层 23到达第二基板 24上的彩色滤光片 (Color Filter) 441。 在本实施例中, 彩色滤光片 441包括多个阵列排布的像素 4411,而各个像 素 4411之间具有间隙 4412。与现有技术不同的是,每个像素 4411包括红色 (R) 子像素 (Sub-pixel) 和绿色 (G) 子像素, 其中, 每个子像素是由与其颜色对 应的光阻沉积在第二基板 24上形成的。 换句话说, 将现有技术的像素中的蓝 色 (B ) 子像素去除形成间隙 4412。 相对应地, 将与彩色滤光片 441上的间隙 4412相对应的荧光粉层去除, 也就是说, 第一基板 22上的与彩色滤光片 441 上的红色子像素、 绿色子像素对应处设置荧光粉层 422。 荧光粉层 422包括红色荧光粉层 RF和绿色荧光粉层 GF。具体地讲,与彩 色滤光片 441上的红色子像素对应的荧光粉层为红色荧光粉层 RF, 与彩色滤 光片 441上的绿色子像素对应的荧光粉层为绿色荧光粉层 GF。 蓝光穿过荧光粉层 422后, 红色荧光粉层 RF将部分蓝光转换为红光, 绿 色荧光粉层 GF将部分蓝光转换为绿光。也就是说,蓝光经过红色荧光粉层 RF 后, 从红色荧光粉层 RF出射蓝光和红光; 而蓝光经过绿色荧光粉层 GF后, 从绿色荧光粉层 GF出射蓝光和绿光。 从红色荧光粉层 RF出射的蓝光和红光 经过彩色滤光片 441上的红色子像素呈现红色, 而从绿色荧光粉层 GF出射的 蓝光和绿光经过彩色滤光片 441上的绿色子像素呈现绿色, 最后红色和绿色显 示在液晶显示器的面板上。而穿过荧光粉层 422中被去除了荧光粉层位置处的 蓝光穿过液晶层 23到达彩色滤光片 441, 并从彩色滤光片上的间隙 4412直接 穿过, 呈现蓝色, 最后显示在液晶显示器的面板上。 在本实施例中, 蓝光 LED可替换为蓝紫光 LED、 紫光 LED、 紫外光 LED 等的短波长 LED。 此外, 为了在液晶显示器的面板上呈现的红色、 绿色和蓝色 能够混色形成白色, 由于红色荧光粉层 RF和绿色荧光粉层 GF会对穿过它们 内部的蓝光进行吸收, 并且红色荧光粉层 RF吸收蓝光的吸收率大于绿色荧光 粉层 GF吸收蓝光的吸收率, 所以本实施例优选地使红色子像素的尺寸、 绿色 子像素的尺寸和间隙的尺寸依次减小。 具体地说, 红色子像素的宽度、 绿色子 像素的宽度和间隙 4412的宽度依次减小。 根据本实施例的液晶显示器, 由于蓝光 LED所发射的蓝光中的一部分直 接穿过液晶层 23, 并通过间隙 4412后显示在液晶显示器的面板上, 减少了荧 光粉层 422及形成蓝色子像素的光阻对其的吸收, 所以提高了光的利用率,进 而提高液晶显示器的整体效率。 图 7是根据本发明的第六实施例的液晶显示器的剖视示意图。 在本实施例的描述中, 与第五实施例相同之处在此不再赘述, 仅描述与第 五实施例不同之处。 参照图 7,与第五实施例不同之处在于,第一基板 22上设置有多个薄膜晶 体管(Thin Film Transistor, TFT )221,经由薄膜晶体管 221的控制,蓝光 LED211 所发射的蓝光穿过液晶层 23和第二基板 24上的荧光粉层 422之后, 到达第二 基板 24上的彩色滤光片 (Color Filter) 441。 也就是说, 在本实施例中, 将荧 光粉层 422设置在第二基板 24之上, 即彩色滤光片 441与液晶层 23之间。 图 8是根据本发明的第七实施例的液晶显示器的剖视示意图。 在本实施例的描述中, 与第五实施例相同之处在此不再赘述, 仅描述与第 五实施例不同之处。 参照图 8, 与第五实施例不同之处在于, 在彩色滤光片 441上的间隙 4412 处设置蓝色 (B ) 子像素。 即在本实施例中, 每个像素 4411包括红色 (R) 子 像素 (Sub-pixel)、 绿色 (G) 子像素和蓝色 (B ) 子像素。 此外, 为了在液晶 显示器的面板上呈现的红色、 绿色和蓝色能够混色形成白色, 由于红色荧光粉 层 RF和绿色荧光粉层 GF会对穿过它们内部的蓝光进行吸收, 并且红色荧光 粉层 RF吸收蓝光的吸收率大于绿色荧光粉层 GF吸收蓝光的吸收率, 所以本 实施例优选地使红色子像素的尺寸、 绿色子像素的尺寸和在间隙 4412处设置 的蓝色子像素的尺寸依次减小。 具体地说, 红色子像素的宽度、 绿色子像素的 宽度和蓝色子像素的宽度依次减小。 根据本实施例的液晶显示器, 由于蓝光 LED所发射的蓝光中的一部分穿 过液晶层 23, 并通过间隙 4412处设置的蓝色子像素后显示在液晶显示器的面 板上, 减少了荧光粉层 422对其的吸收, 所以提高了光的利用率, 进而提高液 晶显示器的整体效率。 图 9是根据本发明的第八实施例的液晶显示器的剖视示意图。 在本实施例的描述中, 与第五实施例相同之处在此不再赘述, 仅描述与第 五实施例不同之处。 参照图 9,与第五实施例不同之处在于,第一基板 22上设置有多个薄膜晶 体管(Thin Film Transistor, TFT )221,经由薄膜晶体管 221的控制,蓝光 LED211 所发射的蓝光穿过液晶层 23和第二基板 24上的荧光粉层 422之后, 到达第二 基板 24上的彩色滤光片 (Color Filter) 441。 也就是说, 在本实施例中, 将荧 光粉层 422设置在第二基板 24之上, 即彩色滤光片 441与液晶层 23之间。 在彩色滤光片 441上的间隙 4412处设置蓝色(B )子像素。 即在本实施例 中, 每个像素 4411包括红色 (R)子像素 (Sub-pixel)、 绿色 (G)子像素和蓝 色 (B ) 子像素。 此外, 为了在液晶显示器的面板上呈现的红色、 绿色和蓝色 能够混色形成白色, 由于红色荧光粉层 RF和绿色荧光粉层 GF会对穿过它们 内部的蓝光进行吸收, 并且红色荧光粉层 RF吸收蓝光的吸收率大于绿色荧光 粉层 GF吸收蓝光的吸收率, 所以本实施例优选地使红色子像素的尺寸、 绿色 子像素的尺寸和在间隙 4412处设置的蓝色子像素的尺寸依次减小。具体地说, 红色子像素的宽度、 绿色子像素的宽度和蓝色子像素的宽度依次减小。 根据本实施例的液晶显示器, 由于蓝光 LED所发射的蓝光中的一部分穿 过液晶层 23, 并通过间隙 4412处设置的蓝色子像素后显示在液晶显示器的面 板上, 减少了荧光粉层 422对其的吸收, 所以提高了光的利用率, 进而提高液 晶显示器的整体效率。 应当注意的是, 上述实施例中的侧入式背光模块(或称侧面发光式背光模 块) 可使用直下式背光模块替代。 图 10是本发明的一种直下式背光模块的剖 视示意图。 参照图 10, 直下式背光模块 61包括光源 (例如蓝光 LED、 紫光 LED等) 611、 反射片 612、 扩散板 613及光学膜片、 固定件等组件。 与侧入式背光模块 中将蓝光 LED211固定于导光板 213的一侧面不同的是,在直下式背光模块中, 光源 611固定设置在扩散板 613的下方。 同样的, 从光源 611所发射的光可经 由反射片 612、扩散板 613等这些组件的组合而向上传到透明玻璃基板。此外, 因后续过程与上述实施例所描述的相同, 所以在此不再赘述
虽然以上实施例已被示出和描述, 但对本领域的技术人员明显的是, 在不 脱离由权利要求限定的本发明的精神和范围的情况下, 可以对其进行修改和变 型。
