Description

折叠式液晶显示器及其制作方法 技术领域
本发明涉及显示技术领域，尤其涉及一种折叠式液晶显示器及其制作方法。
背景技术
平面显示器件具有机身薄、省电、无辐射等众多优点，得到了广泛的应用。现有的平面显示器件主要包括液晶显示器(Liquid Crystal Display，LCD)及有机发光二极管显示器(Organic Light Emitting Display，OLED)。
液晶显示器是目前最常见的平板显示器，其靠着成熟的制作工艺，较低的生产成本，优异的显示画面等优点逐渐占据了如今平板显示器市场中的大部分市场份额。
现有市场上的液晶显示器大部分为背光型液晶显示器，其包括液晶显示面板及背光模组(backlight module)。液晶显示面板又包括：一彩色滤光片基板(Color Filter，CF)、一薄膜晶体管阵列基板(Thin Film Transistor Array Substrate，TFT Array Substrate)以及一配置于两基板间的液晶层(Liquid Crystal Layer)，其工作原理是在两片基板当中放置液晶分子，两片基板中间有许多垂直和水平的细小电线，通过控制液晶层中的电场控制液晶分子改变方向，从而调整从背光模组入射到液晶层的光的偏振，使液晶面板显示图像。
目前，常规的液晶显示器都只具有一个显示面，观众只能从该显示面观察显示画面，并且该显示面的大小在制作完成就不能再改变。然而，目前的消费者既希望显示器具有较大的显示面，又希望显示器便于携带，例如在手机屏幕上，为了便于手机的携带，手机屏幕往往只能局限在一定的尺寸范围内，导致人们不能在手机屏幕上享受大尺寸屏幕显示的图像，同时现有的大尺寸液晶显示器体型庞大，也不利于搬运和运输；同时，在某些应用场景下两个观众可能会需要同时观看不同的信息、节目、或画面，此时单一显示面的液晶显示器就不能满足观众的需求。因此，液晶显示器的应用和使用方式还需拓展。

进一步地，所述第一刚性基板4、与第二刚性基板5可由玻璃、金属、或陶瓷形成，优选薄型玻璃，所述第一及第二柔性衬底12、21可选用任意柔性的且合适的绝缘材料形成，例如，聚酰亚胺、聚碳酸酯、聚醚砜、聚对苯二甲酸乙二醇酯、聚萘二甲酸乙二醇酯、多芳基化合物、或玻璃纤维增强塑料等。具体地，所述折叠部的宽度范围可根据液晶显示器的尺寸和采用该液晶显示器的电子产品的尺寸进行调整，优选0～5mm，更优选0mm、0.1mm、0.2mm等较小的数值。此外，所述折叠式液晶显示器可以通过调整折叠部的液晶的预倾角、或在折叠部设置覆盖所述折叠部的黑色遮光材料等方法来避免所述折叠部产生漏光。
下面利用本发明的优选实施例对本发明进行详细说明，在下述优选实施例中，所述折叠式液晶显示器均包括两个第一刚性基板与两个第二刚性基板，相应形成两个显示部及一个折叠部6，所述两个显示部分别定义为第一显示部91与第二显示部92、
请参阅图1，在本发明的第一实施例中，所述第一显示部91和第二显示部92均采用透射显示，其中，所述第一显示部91的第一偏光片7的远离所述第一刚性基板4的一侧设有第一背光模组101，所述第二显示部92的第一偏光片7的远离所述第一刚性基板4的一侧设有第二背光模组102，也即第一显示部91和第二显示部92的显示面均位于第二柔性基板2一侧，此时可以通过沿所述折叠部6弯折将第一显示部91的第一背光模组101和 第二显示部92的第二背光模组102背向层叠实现双面显示，或将第一显示部91和第二显示部92展开至同一平面组成一个更大显示面。所述第一显示部91和第二显示部92可以共用一个控制电路驱动系统，或分别设置独立的控制电路驱动系统，优选地，所述第一显示部91和第二显示部92共用一个控制电路驱动系统，以减少集成电路数量，节约成本。
请参阅图2，在本发明的第二实施例中，所述第一显示部91和第二显示部92均采用透射显示，其中，所述第一显示部91的第一偏光片7的远离所述第一刚性基板4的一侧设有第一背光模组101，所述第二显示部92的第二偏光片8的远离所述第一刚性基板4的一侧设有第二背光模组102，或者所述第一显示部91的第二偏光片8的远离所述第一刚性基板4的一侧设有第一背光模组101，所述第二显示部92的第一偏光片7的远离所述第一刚性基板4的一侧设有第二背光模组102，也即所述第一显示部91和第二显示部92的显示面一个位于第一柔性基板1一侧
，另一个位于第二柔性基板2一侧，此时可以通过将第一显示部91和第二显示部92展开至同一平面或形成一定的角度，使得观众可以从第一显示部91和第二显示部92分别观看不同的画面，从而丰富液晶显示器的功能，并在携带时可以将第一显示部91和第二显示部92折叠到一起以减小其占用的空间，以便于携带。所述第一显示部91和第二显示部92可以共用一个控制电路驱动系统，或分别设置独立的控制电路驱动系统，优选地，所述第一显示部91和第二显示部92共用一个控制电路驱动系统，以减少集成电路数量，节约成本。
请参阅图3，图3为本发明的第三实施例，该第三实施例与第二实施例的不同之处在于，所述为了使第一显示部91和第二显示部92具有平整的表面，在所述折叠式液晶显示器展开时，其折叠部6具有一个呈一定角度的弯折，从而使第一显示部91和第二显示部92在设置了背光模组之后依然具有平整的表面，具体可以通过调整所述折叠部6的宽度来实现。其余均与第二实施例相同，此处不再赘述。
请参阅图4，在本发明的第四实施例，所述第一显示部91采用透射显示，第二显示部92采用反射显示。所述第一显示部91的第一偏光片7的远离所述第一刚性基板4的一侧设有第一背光模组101，所述第二显示部92的第二柔性基板2靠近所述第一柔性基板1的一侧设有反射层23。若设有反射层一侧的柔性基板为彩膜基板，则所述反射层23设于所述彩膜基板中彩色滤光薄膜与该侧的柔性衬底之间，若设有反射层一侧的柔性基板为阵列基板，则所述反射层23可设于所述该侧柔性基板与液晶层3之间的任 意位置。所述反射层23通常由反射率较高的金属层形成，其可将环境光线中入射到显示器内的光线反射回去，从而为第二显示部92提供一定的显示亮度。此时可以通过将第一显示部91和第二显示部92展开至同一平面或形成一定的角度，观众可从第一显示部91和第二显示部92分别观看不同的画面，从而丰富液晶显示器的功能，并在携带时可以将第一显示部91和第二显示部92折叠到一起以减小其占用的空间，以便于携带。
进一步地，在本发明的第四实施例中，为了使第一显示部91和第二显示部92具有一致或较接近的光学效果，例如RGB色坐标、色饱和度等光学效果，第二显示部92的彩色滤光薄膜的色阻厚度可以为第一显示部91的一半，或者第二显示部92的彩色滤光薄膜的色阻厚度等于第一显示部91，但是第二显示部92的各个像素中色阻被挖空除去部分。为了使第一显示部91和第二显示部92在液晶两端电压相同时，第一显示部91光线一次经过液晶层3和第二显示部92光线两次经过液晶层3所产生的相位延迟一样，从而便于第一显示部91和第二显示部92共用伽马电压驱动系统，可以使第二显示部92的液晶盒厚为第一显示部91的一半左右，也可以改变电极结构，例如，在边缘场开关(Fringe Field Switching，FFS)显示模式中改变狭缝(Slit)电极的间距，使第二显示部92的狭缝电极间距大于第一显示部91，同时第一显示部91和第二显示部92电极结构差异也可以是其他形式，例如电极的角度、高度等。为了获得较好的反射光学效果，第二显示部92的显示模式可以与第一显示部91不一致，第二显示部92的电极结构、液晶初始排布、信号施加方式也可以与第一显示部91不一致。为了获得较好的反射光学效果，第二显示部92的偏光片上可以设置四分之一波片或半波片等光学膜片。
此外，还可以在所述第二显示部92的显示面一侧设置前置背光模组。
请参阅图5，在本发明的第五实施例中，所述第一显示部91和第二显示部92均采用透射显示，其中，所述第一显示部91的第一偏光片7的远离所述第一刚性基板4的一侧设有第一背光模组101，所述第二显示部92的第一偏光片7的远离所述第一刚性基板4的一侧设有第二背光模组102，也即第一显示部91和第二显示部92的显示面均位于第二柔性基板2一侧，且所述第一显示部91与第二显示部92具有不同的可视视角范围。所述第一显示部91与第二显示部92的不同视角范围可通过不同的液晶配向方式、不同的驱动方式、不同的电极设置方式、不同显示模式等一个或者多个方法实现。
具体地，设置第一显示部91和第二显示部92具有共同的显示模式或 者显示像素，所述第一显示部91和第二显示部92均为FFS显示模式，此时第一显示部91与第二显示部92的不同视角范围可通过如下两种方法实现，第一种为：将第二显示部92的彩色滤光薄膜的部分色阻层挖空，形成一窄视角提供区域24，在窄视角提供区域24下方的液晶被配向为竖直排列，从而增大第二显示部92的像素漏光，减弱其大视角的观看对比度、以及清晰度；第二种为：将第二显示部92靠近所述第二柔性基板2一侧的液晶初始排列成较大的预倾角，如30至80deg，高预倾角产生侧向漏光以实现窄视角，此时液晶优选为负性液晶。
具体地，第一显示部91与第二显示部92的不同视角范围还可以通过不同显示模式来实现，如将第一显示部91设置为多畴垂直配向(Multi-domain Vertical Alignment，MVA)显示模式，第二显示部92设置为垂直配向(Vertical Alignment，VA)显示模式。
此外，上述各个折叠式液晶显示器，均可在其外围增设一可挠保护层，对所述折叠式液晶显示器进行保护，并使多个显示部在折叠前后保持整体性，另外，在上述各个折叠式液晶显示器中，当所述折叠部弯折的角度较小和所述折叠部需要经常弯折时，为了防止折叠部出现断裂，还可以增加折叠部的柔性基板的厚度使其大于显示部的厚度，厚度增加的方向可以往液晶盒内增加，也可以是往液晶盒外增加厚度，以提升所述折叠式液晶显示器的使用寿命。
上述各个折叠式液晶显示器中的背光模组可根据需要选择侧入式背光模组、或直下式背光模组。

进一步地，所述第一刚性基板4、与第二刚性基板5可由玻璃、金属、或陶瓷形成，优选薄型玻璃，所述第一及第二柔性衬底12、21可选用任意柔性的任意合适的绝缘材料形成，例如，聚酰亚胺、聚碳酸酯、聚醚砜、聚对苯二甲酸乙二醇酯、聚萘二甲酸乙二醇酯、多芳基化合物、或玻璃纤维增强塑料等。所述第一及第二柔性衬底12、21可通过诸如旋涂、狭缝涂覆、喷墨涂覆等涂布工艺而涂布在刚性母板上。
步骤3、将形成有第一柔性基板1、和第二柔性基板2的第一刚性母板和第二刚性母板对组成盒使得第一柔性基板1与和第二柔性基板2相对设置，并在第一柔性基板1与和第二柔性基板2之间灌入液晶，形成液晶层3。或者在所述第一柔性基板1和第二柔性基板2的一个柔性基板上点滴液晶和涂覆框胶，然后在将两形成有第一柔性基板1、和第二柔性基板2的第一刚性母板和第二刚性母板对组成盒使得第一柔性基板1与和第二柔性基板2相对设置，进而在第一柔性基板1与和第二柔性基板2之间形成液晶层3。
步骤4、切割所述第一刚性母板和第二刚性母板，形成设于所述第一柔性基板1远离所述第二柔性基板2一侧的多个间隔分布的第一刚性基板4、以及设于所述第二柔性基板2远离所述的第一柔性基板1一侧的与所述多个第一刚性基板4相对设置的多个第二刚性基板5；
