参见图5，图5为本申请实施例提供的显示屏的分解示意图。在一些实施例中，滤光层21可以由多个彩色滤光片和黑色矩阵组成。其中，多个彩色滤光片可以包括红色滤光片、绿色滤光片以及蓝色滤光片间隔设置，滤光层21还可以包括黑色矩阵，黑色矩阵设置在所述红色滤光片、所述绿色滤光片以及所述蓝色滤光片的间隔处。参见图6，其中，彩色滤光片可以为红色滤光片211、绿色滤光片212以及蓝色滤光片213。
具体的，滤光层21包括红色滤光片211、绿色滤光片212、蓝色滤光片213以及黑色矩阵214。其中，红色滤光片211、绿色滤光片212以及蓝色滤光片213可以包括扩散粒子且为具有扩散效果的滤光片，当发光层23发射的光线通过滤光层21时，在扩散粒子的作用下可以被扩散至显示屏20外的各个角度。黑色矩阵214可以用于分割相邻色阻，遮挡色彩的空隙，防止漏光或者混色。
在一些实施例中，彩色滤光片的形状可以为多边形，黑色矩阵214的形状也可以为多边形。例如，彩色滤光片的形状可以为矩形，黑色矩阵214的形状也可以为矩形。彩色滤光片包括多个红色滤光片、绿色滤光片以及蓝色滤光片，黑色矩阵包括多个黑色子矩阵，其中，多个红色滤光片、绿色滤光片以及蓝色滤光片与多个黑色子矩阵交替设置并铺满所述滤光层。
例如，请参见图7，图7为本申请实施例提供的显示屏的滤光层的滤光片排列结构示意图。图7示出了滤光层21中，彩色滤光片与黑色矩阵214的排列结构。其中红色滤光片211、绿色滤光片212、蓝色滤光片213以及黑色矩阵214可以为矩形形状，且交替排列在滤光层21。红色滤光片211、绿色滤光片212、蓝色滤光片213以及黑色矩阵214可以通过印刷的方式制作在玻璃层22上。
在一些实施例中，玻璃层22设置在滤光层21与发光层23之间，玻璃层22可以包括至少一块玻璃，该玻璃可以为encap玻璃。利用encap玻璃的抗震能力可以避免终端摔落时造成显示屏20的损坏，可以对显示屏20起到保护作用。此外，encap玻璃可以为透明状态，充当发光层23发射的光线传输过程中的良好介质。
在一些实施例中，发光层23可以包括子像素和边界结构。其中，一般的液晶面板上每个像素由红蓝绿(RGB)三原色组成，每个像素上的每种颜色叫一个"子像素"。发光层23可以包括多个子像素，子像素可以为红色子像素、绿色子像素以及蓝色子像素。发光层23在通电状态下可以通过红色子像素、绿色子像素以及蓝色子像素分别发出红色光线、绿色光线以及蓝色光线。
参见图8，图8为本申请实施例提供的显示屏的发光层的结构示意图。图8中，发光层23可以包括红色子像素231、绿色子像素232、蓝色子像素233以及边界结构234。其中，红色子像素231可以发射红色光线，绿色子像素232可以发射绿色光线，蓝色子像素233可以发射蓝色光线。边界结构234可以用于防止漏光。
在一些实施例中，滤光层21的彩色滤光片与发光层23的子像素可以据相同颜色相对设置，红色滤光片211、绿色滤光片212以及蓝色滤光片213与红色子像素231、绿色子像素232以及蓝色子像素233可以根据相同颜色相对设置。
具体的，参加图9，图9为本申请实施例提供的显示屏的滤光层与发光层的对应关系示意图。图9示出了发光层23发射的光线与滤光层21接收的光线的对应关系。比如，发光层23的红色子像素231可以对应滤光层的红色滤光片211进行设置，红色子像素231发出的红色光线可以通过红色滤光片211进行扩散、绿色子像素232可以对应滤光层的绿色滤光片212进行设置，绿色子像素232发出的绿色光线可以通过红色滤光片212进行扩散、蓝色子像素233可以对应滤光层的蓝色滤光片213进行设置，蓝色子像素233发出的蓝色光线可以通过蓝色滤光片213进行扩散。
在一些实施例中，基板24可以为透明塑料、玻璃或者金属箔等等。基板24可以用来支撑整个显示屏20。显示屏20可以包括硬屏和柔性屏。若显示屏20为硬屏，则基板24可以为玻璃基板，若显示屏20为柔性屏，则基板24可以为PI（Polyimide，软性塑料）基板。
本申请实施例公开了一种显示屏及终端。该显示屏包括依次排列的滤光层、发光层以及基板，所述滤光层包括具有扩散效果的彩色滤光片。该方案提出的显示屏通过设置彩色滤光片，将发光层发射的光线通过扩散粒子作用扩散至各个角度，从而可以有效扩大终端的显示屏视角。
