图1是根据本发明的实施例的显示装置的架构图;
图2是根据本发明的实施例的信号控制器的模块图;

以下,将参照附图来详细描述本发明的实施例。然而,可以以许多不同的形式来实施本发明,并且本发明不应该被解释为限制于这里阐述的具体实施例。相反,提供这些实施例是为了解释本发明的原理及其实际应用,从而使本领域的其他技术人员能够理解本发明的各种实施例和适合于特定预期应用的各种修改。
图1是根据本发明的实施例的显示装置的架构图。
参照图1,根据本发明的实施例的显示装置包括:显示面板组件100和信号控制器200。
显示面板组件100包括:阵列排布的多个像素PX、N条扫描线G1至GN、M条数据线D1至DM、扫描驱动器110、第一数据驱动器120a和第二数据驱动器120b。在本实施例中,示出了两个数据驱动器,但本发明并不限制于此,例如在更高分辨了的显示装置中,可以包括三个或者更多个数据驱动器。
每个像素PX连接到对应的扫描线和对应的数据线。每个像素PX可以包括:开关器件(未示出),连接到对应的扫描线和对应的数据线;发光单元(未示出),连接到该开关器件。在本实施例中,该开关器件可优选为薄膜晶体管,但本发明并不限制于此。发光单元可例如是液晶发光单元或者有机发光单元。
扫描驱动器110连接到扫描线G1至GN,并向扫描线G1至GN施加扫描信号,该扫描信号通常由高电平信号和低电平信号组合而成。
第一数据驱动器120a连接到数据线D1至DM/2,并向数据线D1至DM/2施加数据电压;第二数据驱动器120b连接到数据线D(M+2)/2至DM,并向数据线D(M+2)/2至DM施加数据电压。
在本实施例中,扫描驱动器110、第一数据驱动器120a和第二数据驱动器120b被集成而包括于液晶面板组件100中。可替换地,扫描驱动器110、第一数据驱动器120a和第二数据驱动器120b可以被安装在柔性印刷薄膜(未示出)上,然后附接到液晶面板组件100(此时液晶面板组件100不包含扫描驱动器110、第一数据驱动器120a和第二数据驱动器120b)。
信号控制器200控制扫描驱动器110、第一数据驱动器120a和第二数据驱动器120b的操作。
信号控制器200能够产生扫描控制信号CONT1和数据控制信号CONT2。信号控制器200将扫描控制信号CONT1传送到扫描驱动器110,并将数据控制信号CONT2分别传送到第一数据驱动器120a和第二数据驱动器120b。
第一数据驱动器120a和第二数据驱动器120b分别响应于数据控制信号CONT2并根据各自存储的伽马代码(Gamma Code)产生数据电压,并分别将数据电压施加到数据线D1至DM/2和数据线D(M+2)/2至DM。
扫描驱动器110响应于扫描控制信号CONT1向扫描线G1至GN施加为高电平信号的扫描信号而导通连接到扫描线G1至GN的开关器件。然后,分别施加到数据线D1至DM/2和数据线D(M+2)/2至DM的数据电压通过导通的开关器件而被传送到每个像素PX。
诚如背景技术中描述,由于第一数据驱动器120a和第二数据驱动器120b
在制程时产生的差异,第一数据驱动器120a和第二数据驱动器120b各自输出的数据电压不同,从而使显示装置产生显示分屏现象,而显示画面在第一数据驱动器120a连接的数据线DM/2和第二数据驱动器120b连接的数据线D(M+2)/2之间出现显示分屏现象最明显。
为了消除上述显示分屏现象,使多个像素PX显示同灰阶的单色画面,信号控制器200获取第一数据驱动器120a连接的数据线Di和第二数据驱动器120b连接的数据线Dj上的电压数据,并且信号控制器200根据获取到的电压数据对第一数据驱动器120a和第二数据驱动器120b中的伽马代码进行调整,直至第一数据驱动器120a输出至数据线Di上的数据电压和第二数据驱动器120b输出至数据线Dj上的数据电压相同,其中,1≤i≤M/2,(M+2)/2≤j≤M。
优选地,由于连接第一数据驱动器120a的数据线DM/2和连接第二数据驱动器120b的数据线D(M+2)/2彼此相邻,显示画面在数据线DM/2和数据线D(M+2)/2之间出现分屏现象最明显,为了更有效地消除上述分屏现象,使多个像素PX显示同灰阶的单色画面,信号控制器200可获取第一数据驱动器120a连接的数据线DM/2和第二数据驱动器120b连接的数据线D(M+2)/2上的电压数据,并且信号控制器200根据获取到的电压数据对第一数据驱动器120a和第二数据驱动器120b中的伽马代码进行调整,直至第一数据驱动器120a输出至数据线DM/2上的数据电压和第二数据驱动器120b输出至数据线D(M+2)/2上的数据电压相同。
进一步地,信号控制器200将调整后的伽马代码分别写入第一数据驱动器120a和第二数据驱动器120b中。
图2是根据本发明的实施例的信号控制器的模块图。
参照图2,根据本发明的实施例的信号控制器200包括:电压检测转换模块210、控制模块220以及写入模块230。
优选地,电压检测转换模块210可为模数转换器(DAC),但本发明并不限制于此。当多个像素PX同时显示同灰阶的单色画面时,电压检测转换模块210检测第一数据驱动器120a连接的数据线Di上的第一数据电压和第二数据驱动器120b连接的数据线Dj上的第二数据电压,并将第一数据电压和第二数
据电压分别转换为第一数字信号和第二数字信号(即电压数据)。
电压检测转换模块210将第一数字信号和第二数字信号输送至控制模块220。控制模块220比对第一数字信号和第二数字信号的差异,并根据差异结果调整第一数据驱动器120a和第二数据驱动器120b中的伽马代码,直至第一数据驱动器120a输出至数据线Di上的数据电压和第二数据驱动器120b输出至数据线Dj上的数据电压相同。这里,控制模块220可以以第一数据驱动器120a中的伽马代码为基准,调整第二数据驱动器120b中的伽马代码;或者控制模块220可以以第二数据驱动器120b中的伽马代码为基准,调整第一数据驱动器120a中的伽马代码;或者控制模块220以一预定的伽马代码为基准,分别调整第一数据驱动器120a和第二数据驱动器120b中的伽马代码。
控制模块220将调整后的伽马代码输送至写入模块230。写入模块230将调整后的伽马代码写入第一数据驱动器120a和第二数据驱动器120b中。
图3是根据本发明的实施例的显示装置显示分屏的消除方法的流程图。

S330:利用信号控制器200根据获取到的电压数据对第一数据驱动器120a和第二数据驱动器120b中的伽马代码进行调整,直至第一数据驱动器120a输出至数据线Di上的数据电压和第二数据驱动器120b输出至数据线Dj上的数据电压相同。
结合参照图2,实现步骤S330的具体方法包括:首先,利用信号控制器200的控制模块220比对第一数字信号和第二数字信号的差异;接着,利用信号控制器200的控制模块220根据差异结果调整第一数据驱动器120a和第二数据驱动器120b中的伽马代码,直至第一数据驱动器120a输出至数据线Di上的数据电压和第二数据驱动器120b输出至数据线Dj上的数据电压相同。
这里,控制模块220可以以第一数据驱动器120a中的伽马代码为基准,调整第二数据驱动器120b中的伽马代码;或者控制模块220可以以第二数据驱动器120b中的伽马代码为基准,调整第一数据驱动器120a中的伽马代码;或者控制模块220以一预定的伽马代码为基准,分别调整第一数据驱动器120a和第二数据驱动器120b中的伽马代码。
S340:利用信号控制器200将调整后的伽马代码分别写入第一数据驱动器120a和第二数据驱动器120b中。
结合参照图2,实现步骤S340的具体方法包括:利用信号控制器200的写入模块230将调整后的伽马代码分别写入第一数据驱动器120a和第二数据驱动器120b中。
此外,根据本发明的上述方法可以被实现为计算机可读记录介质中的计算机代码。本领域技术人员可以根据对上述方法的描述来实现所述计算机代码。当所述计算机代码在计算机中被执行时实现本发明的上述方法。
此外,根据本发明的实施例的显示装置中的各个器件或模块可被实现为硬件组件。本领域技术人员根据限定的各个器件或模块所执行的处理,可以使用例如现场可编程门阵列(FPGA)或专用集成电路(ASIC)来实现各个器件或模块。
综上所述,根据本发明的实施例,消除了高分辨率显示装置中由于使用至少两个数据驱动器而引起的显示分屏现象,从而提高显示装置的显示效果。
虽然已经参照特定实施例示出并描述了本发明,但是本领域的技术人员将理解:在不脱离由权利要求及其等同物限定的本发明的精神和范围的情况下,可在此进行形式和细节上的各种变化。
