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是本发明提供的终端的功能模块示意图。
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作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，本发明提供一种显示屏驱动器10、显示屏及终端20，所述显示屏驱动器用于处理终端处理器20发送的图像数据并传给显示屏以驱动显示屏。所述显示屏包括与显示屏驱动器电连接的显示面板，所述显示屏为液晶显示屏。所述终端可以为手机或者显示器，本实施例中一手机为例。所述终端包括主板，所述主板设有处理器21，处理器21连接所述显示屏驱动器10用以驱动所述显示屏驱动器。
本实施例中，所述驱动器10包括数据接收器11、图像处理模块12、数据存储器13、时序控制器14及源极驱动器15。
所述数据接收器11接收所述终端处理器21发送的图像数据并传递给所述图像处理模块12。所述图像处理模块12处理所述数据接收器11传送的图像数据。本实施例中，所述图像处理模块12包括色彩增强模块121及动态背光调节模块122，所述色彩增强模块121增强所述数据接收器传送的图像数据所 要显示的面图的色彩，所述动态背光调节模块122调节经所述色彩增强模块处理的图像数据的背光灰度及亮度。还可以包括白平衡调节模块，图像数据锐度增强模块等，图中未示。
所述数据存储器13存储所述图像处理模块12处理后的图像数据；所述显示屏驱动器10还包括所述脉冲宽度调制寄存器16。所述脉冲宽度调制寄存器16存储所述图像处理模块12处理图像数据后产生的背光调节信号。
所述时序控制器14控制所述源极驱动器15接收所述数据存储器13传递的图像数据并送出。本实施例中，所述显示屏还包括薄膜晶体管开关器件，所述源极驱动器连接所述薄膜晶体管开关器件的源极，以实现驱动器对显示屏的驱动。
请再次参阅图1，当所述终端处理器21发送静态图像数据，所述数据接收器接11收的静态图像数据经过所述图像处理模块12处理，所述脉冲宽度调制寄存器16存储所述图像处理模块12第一帧处理静态图像数据产生的背光调节信号，经过所述图像处理模块12处理后的静态图像数据存储至所述数据存储器13，时序控制器14控制所述数据存储器13内存储的静态图像数据传递给所述源极驱动器15，同时输出所述脉冲宽度调制寄存器16存储的背光调节信号。

当所述终端的处理器21发送的动态图像数据数时，所述数据接收器11接收的动态图像数据经过所述图像处理模块12进行处理后存储至所述数据存储器13，所述脉冲宽度调制寄存器16存储所述图像处理模块12每次处理动态图像数据产生的动态背光调节信号，所述时序控制器14控制源极驱动器15读取所述数据存储器13内存储的动态图像数据，同时读取所述脉冲宽度调制寄存器16存储的动态背光调节信号对背光进行调节。
以上所揭露的仅为本发明较佳实施例而已，当然不能以此来限定本发明之权利范围，本领域普通技术人员可以理解实现上述实施例的全部或部分流程，并依本发明权利要求所作的等同变化，仍属于发明所涵盖的范围。
