具体实施方式
下面将结合本申请实施例中的附图,对本申请实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本申请一部分实施例,而不是全部的实施例。基于本申请中的实施例,本领域普通技术人员在没有付出创造性劳动前提下所获得的所有其他实施例,都属于本申请保护的范围。
本申请的描述中,除非另有明确的规定和限定,术语“连接”应做广义理解,例如,可以是固定连接,也可以是可拆卸连接,或一体地连接;可以是直接相连,也可以通过中间媒介间接相连,也可以是两个元件内部的连通;可以是通讯连接;可以是电连接。对于本领域的普通技术人员而言,可以根据具体情况理解上述术语在本申请中的具体含义。
本申请的描述中,术语“和/ 或”是指相关联列出的项中的一个或多个的任何组合以及所有可能组合,并且包括这些组合。
请参阅图1,图1为本申请第一实施例提供的显示屏结构框图。
如图1所示,第一实施例中,所述显示屏1包括:自发光显示组件10、反射式液晶显示组件20以及控制器30。所述控制器30分别与自发光显示组件10和反射式液晶显示组件20连接。所述控制器30用于获取当前环境光的亮度值,并根据所述环境光的亮度值不同选择性地:
控制所述自发光显示组件10工作进行发光显示;或,
控制所述反射式液晶显示组件20工作,以利用环境光进行显示;或,
控制所述自发光显示组件10工作进行发光显示,并控制所述反射式液晶显示组件20工作,以利用环境光进行显示。
由于反射式LCD屏在光照亮度高时显示效果好,且能耗小,但在光照亮度低时显示效果不好,OLED屏在光照亮度高时,需要增大电流以增强显示亮度,会加快其老化,缩短其寿命,且环境光在其表面反射影响显示效果,因此,本申请中,所述显示屏1包括所述自发光显示组件10和所述反射式液晶显示组件20,结合了OLED屏可以在环境光亮度低的地方显示效果好、轻薄的优点,反射式LCD屏利用环境光进行显示更加护眼节能的优点,通过使所述自发光显示组件10和所述反射式液晶显示组件20的优势互补,从而使得所述显示屏1在各种光照亮度环境下都具有良好的显示效果,同时能耗更低,寿命更长,机身轻薄,现有的生产技术也容易生产。
进一步地,所述控制器30用于在所述亮度值大于或等于第一预设亮度值时,控制自发光显示组件10不工作,且控制反射式液晶显示组件20工作以利用环境光进行显示。所述控制器30用于在所述亮度值小于第一预设亮度值且大于第二预设亮度值时,控制所述自发光显示组件10工作以进行发光显示,同时控制所述反射式液晶显示组件20工作以利用环境光进行显示,其中,所述第二预设亮度值小于所述第一预设亮度值。所述控制器30用于在所述亮度值小于或等于第二预设亮度值时,控制所述自发光显示组件10工作以进行发光显示,且控制反射式液晶显示组件20不工作。
由于所述自发光显示组件10在环境光亮度较高时需要增大驱动电流,以提高显示亮度使图像在高亮度的环境中显示清楚,同时由于环境光在所述自发光显示组件10的表面反射会影响其显示效果,因此在环境光亮度值大于或等于第一预设亮度值时,由所述反射式液晶显示组件20利用环境光完成显示任务,此时所述反射式液晶显示组件20显示效果好,且耗电少,所述自发光显示组件10此时不需要进行显示,有利于延长所述自发光显示组件10的寿命。在环境光亮度值小于第一预设亮度值且大于第二预设亮度值时,所述反射式液晶显示组件20继续利用环境光与所述自发光显示组件10一同完成显示任务,减少能耗,同时环境光不是在所述自发光显示组件10表面反射,而是经所述反射式液晶显示组件20反射用于显示,将环境光从影响所述自发光显示组件10显示效果的因素变成参与显示的资源,合理有效利用资源。在环境光亮度值小于或等于第二预设亮度值时,环境光在所述自发光显示组件10的表面反射对其显示效果影响很小,所述反射式液晶显示组件20利用环境光辅助显示帮助不大,且消耗能源,因此仅由所述自发光显示组件10发光进行显示。通过根据环境光的亮度值控制由所述自发光显示组件10发光,和/或所述反射式液晶显示组件20利用环境光完成显示任务,从而合理利用所述自发光显示组件10和所述反射式液晶显示组件20各自的优势。
其中,在一实施例中,所述自发光显示组件10可以是但不仅限于OLED、LED等通过自身结构可发出多种颜色光的器件。其中,所述自发光显示组件10采用透明电极,可以是阴极与阳极都采用AZO(ZnO:Al,铝掺杂的氧化锌)、SWNT(Single-Walled carbon NanoTube,单壁的碳纳米管)、ITO(In2O3:Sn,氧化铟锡)等等,这里不做具体限制。

其中,所述液晶层22包括液晶分子以及配向膜。
其中,所述控制器30可以在光传感器检测到光亮度值时,获取光亮度值。

其中,所述滤光层23包括黑矩阵(简称:BM)与彩膜(简称:CF)。
进一步地,所述显示屏1还包括第一透明基板40与第二透明基板50;所述自发光显示组件10与所述反射层25之间自所述自发光显示组件10依次设有所述第一透明基板40、所述液晶层22、所述滤光层23、所述第二透明基板50与所述第二偏光片24。
其中,文中描述“A”与“Z”之间自“A”依次设有“B”、“C”、“D”……,仅表示彼此的相对位置关系依次为“A”、“B”、“C”、“D”……“Z”,但是“A”与“B”之间、“B”与“C”之间、“C”与“D”之间……还可以设置其他结构。
其中,所述第一透明基板40与所述第二透明基板50可以是但不仅限于透明玻璃基板等。
本实施例中,所述显示屏1中所述自发光显示组件10发光进行显示时,发出的光仅需要穿过所述第一偏光片21即可被人眼所看见,光损失较少,显示效果更好。
进一步地,所述反射式液晶显示组件20包括透明公共电极26,所述自发光显示组件10包括透明阴极11、透明阳极13;所述透明公共电极26位于所述液晶层22与所述滤光层23之间,所述透明阴极11与透明公共电极26之间产生电场改变所述液晶层22中的液晶分子的方向;所述透明阴极11与所述透明阳极13之间导通时所述自发光显示组件10发光。

本实施例中,所述自发光显示组件10的所述透明阴极11,同时也是所述反射式液晶显示组件20的像素电极,可以使所述显示屏1结构更加紧凑。
请结合参阅图2与图3,图3为本申请第一实施例提供的TFT电路示意图。
如图2与图3所示,当所述自发光显示组件10的所述透明阴极11,同时也是所述反射式液晶显示组件20的像素电极,第一薄膜晶体管Q10的与第二薄膜晶体管Q11与同一栅线(英文:Gate)连接,与不同的数据线连接,第一薄膜晶体管Q10与数据线2(英文:Data2)连接,第二薄膜晶体管Q11与数据线1(英文:Data1)连接,第二薄膜晶体管Q11的漏极(英文缩写:D)与所述透明阴极11(即像素电极)连接,图3中每个像素单元可以看作是像素电极与公共电极之间夹了一层液晶,将液晶层等效为Clc1,同时为了让充好电的电压能保持到下一次更新画面的时刻,因此还加有储存电容(用Cst1表示)。第一薄膜晶体管Q10的漏极(英文缩写:D)一方面通过储存电容(英文缩写:Cst2)与电源线(英文缩写:VDD)连接,另一方面与第三薄膜晶体管Q12的栅极(英文缩写:G)连接,第三薄膜晶体管Q12的漏极(D)与电源线(英文缩写:VDD)连接,第三薄膜晶体管Q12的源极(英文缩写:S)与所述自发光显示组件10的透明阳极13(图3中用D10表示)连接。
其中,当通过Data1向所述透明阴极11(即像素电极)加一显示电压,所述透明阴极11与所述透明公共电极26之间产生电场,所述反射式液晶显示组件20进行显示工作,同时通过Data2向所述透明阳极13加一与所述显示电压大小相等的电压,所述自发光显示组件10便不能工作。
其中,当通过Data1向所述透明阴极11(即像素电极)加一显示电压,所述透明阴极11与所述透明公共电极26之间产生电场,所述反射式液晶显示组件20进行显示工作,同时Data2向所述透明阳极13加一与所述显示电压大小不相等的电压,则所述自发光显示组件10也可以发光进行显示。
其中,当通过Data1向所述透明阴极11(即像素电极)加一不显示电压,所述透明阴极11与所述透明公共电极26之间不能产生电场,所述反射式液晶显示组件20不能进行显示工作,同时Data2向所述透明阳极13加一与所述不显示电压大小不相等的电压,则所述自发光显示组件10可以发光进行显示工作。
请参阅图4,图4为本申请第二实施例提供的显示屏结构示意图。
如图4所示,第二实施例与第一实施例相似,但与第一实施例不同的是,所述反射式液晶显示组件20包括透明公共电极26与透明像素电极27,所述透明公共电极26与所述透明像素电极27分别位于所述液晶层22的两侧,所述透明像素电极27与所述透明公共电极26之间产生电场改变所述液晶层22中的液晶分子的方向。所述自发光显示组件10包括透明阴极11与透明阳极13;所述透明阴极11与所述透明阳极13之间导通时所述自发光显示组件10发光。
本实施例中,与第一实施例相比,将所述透明像素电极27与所述透明阴极11分别独立设置,从而通过不同的TFT进行控制。可以理解的是,在另一些实施例中,所述透明公共电极26也可以与透明像素电极27设置在所述液晶层22的同一侧。
请参阅图5,图5为本申请第三实施例提供的显示屏结构示意图。
如图5所示,所述第三实施例与所述第一实施例相似,但与第一实施例不同的是,所述显示屏1还包括第一透明基板40与第二透明基板50;所述自发光显示组件10与所述第一偏光片21之间自所述自发光显示组件10依次设有所述液晶层22与所述第一透明基板40;所述反射层25与所述自发光显示组件10之间自所述反射层25依次设有所述第二偏光片24、所述第二透明基板50与所述滤光层23。
进一步地,所述反射式液晶显示组件20包括透明公共电极26,所述自发光显示组件10包括透明阴极11与透明阳极13;所述透明公共电极26位于所述第一透明基板40与所述液晶层22之间,所述透明公共电极26与透明阴极11配合产生电场改变所述液晶层22中的液晶分子的方向;所述透明阴极11与所述透明阳极13之间导通时所述自发光显示组件10发光。
本实施例中,与第一实施例不同的是,将所述自发光显示组件10设置在所述液晶层22与所述滤光层23之间,同时,由于所述自发光显示组件10的所述透明阴极11即为所述反射式液晶显示组件20的像素电极,因此,相比于第一实施例,将所述自发光显示组件10的结构进行了倒置,所述透明公共电极26也相应的相对于所述透明阴极11设置在所述液晶层22的另一侧。可以理解的是,在另一些实施例中,所述透明公共电极26也可以与所述透明阴极11设置在所述液晶层22的同一侧。

请参阅图8,为本申请一实施例提供的显示控制方法进一步的流程图。
进一步地,如图8所示,在S01:获取当前环境光的亮度值后,S02:根据所述环境光的亮度值的不同选择性地:“控制所述自发光显示组件工作进行发光显示,或控制所述反射式液晶显示组件工作,以利用环境光进行显示,或,控制所述自发光显示组件工作进行发光显示并控制所述反射式液晶显示组件工作,以利用环境光进行显示”包括:

在上述实施例中,对各个实施例的描述都各有侧重,某个实施例中没有详述的部分,可以参见其他实施例的相关描述。
以上是本申请实施例的实施方式,应当指出,对于本技术领域的普通技术人员来说,在不脱离本申请实施例原理的前提下,还可以做出若干改进和润饰,这些改进和润饰也视为本申请的保护范围。
