附图说明
为了更清楚地说明本发明实施例或现有技术中的技术方案,下面将对实施 例或现有技术描述中所需要使用的附图作简单地介绍,显而易见地,下面描述中的附图仅仅是本发明的一些实施例,对于本领域普通技术人员来讲,在不付出创造性劳动的前提下,还可以根据这些附图获得其他的附图。
图1是本发明较佳实施方式中的液晶显示装置结构示意图。
具体实施方式
下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅是本发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本发明保护的范围。
请参阅图1,本发明的较佳实施例提供了一种液晶显示装置,其包括背光模组10及液晶面板20。所述液晶面板20包括彩膜基板21、阵列基板22及夹持于彩膜基板21与阵列基板22之间的液晶层23。所述背光模组10为蓝色光源。所述阵列基板22包括玻璃基板221及设于玻璃基板221的彩色层222、与彩色层222叠加设置的偏光层223。所述偏光层223与所述液晶层23相邻设置。所述彩色层222包括蓝光滤光膜层224及彩色单元层225。所述彩色单元层包括数个彩色单元(图未标),每一彩色单元包括红色量子棒层(R)226、绿色量子棒层(G)227及透明彩色滤光层(T)228。其中,所述红色量子棒层226与绿色量子棒层227层叠设于所述蓝光滤光膜层224上,所述透明彩色滤光层228叠设于所述偏光层223。其中,所述红色量子棒层226及绿色量子棒层227的长轴方向垂直于所述背光模组10出光方向。
本实施例中,所述液晶显示装置还包括胶框,胶框位于所述彩膜基板21与阵列基板22之间密封所述液晶层23。所述彩膜基板21背向所述液晶层23的表面设有偏光片211。所述阵列基板22还包括配向层(图未示)及驱动阵列单元层220。所述驱动阵列单元层220设于所述玻璃基板221上,所述配向层设于所述驱动阵列单元层220上,所述彩色层设于所述配向层上。所述偏光层223位于所述彩色层222上并与所述液晶层相邻设置。所述红色量子棒层226与绿色量子棒层227层叠设于所述蓝光滤光膜层224上,所述透明彩色滤光层225叠设于所述偏光层223,并且与所述红色量子棒层226、绿色量子棒 层227及蓝光滤光膜层224组成的层结构的厚度相同。
本发明的所述液晶显示装置中,所述彩色层222即相当于液晶显示面板中的像素层,使用量子棒代替传统的彩色像素滤光晶片结构,由于量子棒发光特性具有和量子点相类似的特性,其发光光谱波长可通常量子点棒的直径进行调节,而且当蓝光(无论自然光还是偏振光)激发量子棒发光后,量子棒会发出偏振光,背光模组的光源为蓝色光源,所以,对于本发明所述的液晶显示装置中,采用量子棒作为彩色层,避免彩色层之间的不同色彩互相吸收光源,可以在光源能耗上相对传统液晶显示器的大幅度降低,同时提高画面的高色饱和。其中,由于背光模组的光源为蓝色光源,蓝光激发红色量子棒后,存在蓝光残留,由于残留蓝光的存在,会降低红光的色纯度,而本申请采用蓝光滤光膜层224与红色量子棒层(R)226及绿色量子棒层(G)227配合,有效的避免红色量子棒残留蓝光而受到影响,可以保证色彩饱和度。
进一步的,所述红色量子棒层226及绿色量子棒层227的长轴方向与所述偏光层223的透过轴方向平行,可以实现液晶面板具有较高的对比度。
进一步的,所述阵列基板20还设有数个隔离柱(图未示),所述穿插于所述红色量子棒层与绿色量子棒层之间,红色量子棒层与透明彩色滤光层之间以及绿色量子棒层与透明彩色滤光层之间。所述隔离柱可支撑于所述彩膜基板21及阵列基板22之间,同时可以防止所述红色量子棒层与绿色量子棒层荧光再吸收现象,提升发光效率。
