附图说明
为了更清楚地说明本发明实施例中的技术方案,下面将对实施例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性的前提下,还可以根据这些附图获得其他的附图。
图1为本发明实施例提供的一种显示面板的结构示意图;
图2为本发明实施例提供的一种显示装置的结构示意图;
图3为本发明实施例提供的一种显示面板的驱动方法流程图;
图4为本发明另一实施例提供的一种显示面板的驱动方法流程图。
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。
本发明的说明书和权利要求书及所述附图中的术语“第一”、“第二”等是用于区别不同对象,而不是用于描述特定顺序。此外,术语“包括”和“具有”以及它们任何变形,意图在于覆盖不排他的包含。例如包含了一系列步骤或单元的过程、方法、系统、产品或设备没有限定于已列出的步骤或单元,而是可选地还包括没有列出的步骤或单元,或可选地还包括对于这些过程、方法、产品或设备固有的其它步骤或单元。
在本文中提及“实施例”意味着,结合实施例描述的特定特征、结构或特 性可以包含在本发明的至少一个实施例中。在说明书中的各个位置出现该短语并不一定均是指相同的实施例,也不是与其它实施例互斥的独立的或备选的实施例。本领域技术人员显式地和隐式地理解的是,本文所描述的实施例可以与其它实施例相结合。
请参阅图1,本发明实施例提供一种显示面板10,所述显示面板10包括多条间隔设置的数据线100、多条间隔设置的扫描线200、多个像素驱动电路300及一驱动器400,所述扫描线200与所述数据线100交叉设置,相邻的两条数据线100及相邻的两条扫描线200之间形成像素区域500,各像素驱动电路300设置在相应的像素区域500内,且各像素驱动电路300分别与相应的数据线100和扫描线200连接,各像素驱动电路300包括存储电容310。
所述驱动器400电连接所述多条数据线100,用于提供充电电压,所述充电电压包括预充电电压及数据电压,其中,所述预充电电压的电压值大于所述数据电压的电压值,所述充电电压被提供给连接在同一条数据线100上的各存储电容310,以使得连接在同一条数据线100上的各存储电容310的存储电容值在预设时间内达到预设电容值。
可以理解的是,如果仅提供数据电压对储存电容310充电,所述储存电容310的有效电容值是等于数据电压在预设时间内对储存电容310充电的总量和。由于在显示面板10一般包括多个储存电容310,且在同一条数据线100上的储存电容310与所述驱动器400的距离不相同,尤其对于远离所述驱动器400的储存电容310,其接受被提供的数据电压具有滞后性,进而导致对储存电容310充电后的有效电容值不足,从而引起显示面板10显示效果的不均匀。本发明实施例中通过在提供数据电压之前,提供预充电电压对储存电容310充电,由于预充电电压的电压值大于数据电压,在预设时间内对储存电容310充电,储存电容310的有效电容值总和会大于仅提供数据电压对储存电容310充电的 有效电容值总和,进而可以改善显示面板10显示画面不均的问题。
在进一步的实施例中,对于同一存储电容310而言,所述预充电电压先于所述数据电压被提供。所述预充电电压首先被提供,可避免储存电容310被击穿的风险。因为预充电电压相对数据电压来说为高压,如果先提供数据电压对储存电容充电,储存电容值达到一定的数值后,再采用预充电电压对其充电,可能存在预充电电压较高而击穿所述储存电容310的风险。
在进一步的实施例中,在同一条数据线100上,连接第n条扫描线200的所述像素驱动电路300记为第n像素驱动电路300a,所述第n像素驱动电路300a中的所述储存电容310记为第n储存电容310a,提供给所述第n储存电容310a的所述充电电压记为第n充电电压。所述驱动器400根据所述第n存储电容310a与所述驱动器400之间的距离确定第n充电电压中的预充电电压的电压值及充电时间。
在进一步的实施例中,对于同一条数据线100上任一个所述储存电容310而言,当任意一个存储电容310被提供的所述预充电电压的电压值相等时,距离所述驱动器400越远的所述存储电容310被提供的所述预充电电压的预充电时间越长。
举例说明,在同一条数据线100上,连接第n-1条扫描线200的所述像素驱动电路300记为第n-1像素驱动电路300b,其中所述第n-1条扫描线200与所述第n条扫描线200相邻设置。所述第n-1像素驱动电路300b中的所述储存电容310记为第n-1储存电容310b,提供给所述第n-1储存电容310b的所述充电电压记为第n-1充电电压。所述第n-1储存电容310b与所述驱动器400之间的距离记为第n-1距离。所述第n储存电容310a与所述驱动器400之间的距离记为第n距离。所述第n-1充电电压中的所述预充电电压记为第n-1预充电电压,所述第n-1预充电电压的充电时间记为第n-1预充电时间, 所述第n预充电电压的充电时间记为第n预充电时间。
当第n-1预充电电压的电压值等于第n预充电电压的电压值时,所述第n-1距离小于所述第n距离时,所述第n预充电时间大于所述第n-1预充电时间。也就是说,当驱动器400提供给同一条数据线100上中储存电容310的预充电电压的电压值相等时,距离驱动器400较远的第n储存电容310a所需要的第n预充电时间大于距离驱动器400较近的第n-1储存电容310b所需要的第n-1预充电时间,以此来弥补因距离较远而充电不足的储存电容310b的电容值,以使电容值总和达到预设电容值。
在进一步的实施例中,对于同一条数据线100上任一个所述储存电容310而言,当任意一个存储电容310被提供的所述预充电电压的充电时间相等时,距离所述驱动器400越远的所述存储电容310被提供的所述预充电电压的电压值越大。
举例说明,所述第n-1充电电压中的所述预充电电压记为第n-1预充电电压,所述第n-1预充电电压的电压值记为第n-1预充电电压值,所述第n预充电电压的电压值记为第n预充电电压值。当第n-1预充电电压的充电时间等于第n预充电电压的充电时间时,所述第n-1距离小于所述第n距离时,所述第n预充电电压值大于所述第n-1预充电电压值。也就是说,当驱动器400提供给同一条数据线100上中储存电容310的预充电电压的充电时间相等时,距离驱动器400较远的第n储存电容310a所需要的第n预充电电压值大于距离驱动器400较近的第n-1储存电容310b所需要的第n-1预充电电压值。以此来弥补因距离较远而充电不足的储存电容310b的电容值,以使电容值总和达到预设电容值。
除了上面单独使用预充电电压值和预充电电压时间来实现本发明技术方案以外,还可以同时调节预充电电压值和预充电时间来给储存电容充电,以解 决远端储存电容的电容值不足现象。
可以理解的是,当任意一个存储电容310被提供的所述预充电电压的充电时间相等时,所述第n距离和所述第n预充电电压值之间的对应信息形成第一对应信息,所述第一对应信息储存在所述驱动器400中。所述驱动器400读取所述第一对应信息,并根据所述第一对应信息为所述第n储存电容提供预充电电压的电压值。对于在同一条数据线100上的每一个储存电容310,所述驱动器400中均储存了与所述储存电容310相对应的第一对应信息,对于不同位置的储存电容,其第一对应信息不一样。可以理解的是,所述第一对应信息可通过对显示面板10中每个储存电容310进行测试得到,将测试后的数据储存到驱动器400中,其中测试方法可以将同一条数据线上选取距离所述驱动器400最近端、中端及最远端的三个储存电容,然后根据这三个储存电容的数据,采用内插法得到其他储存电容的数据,以得到整条数据线上每一个储存电容的第一对应信息。
可以理解的是,所述驱动器400中可包括寄存器,所述第一对应信息储存在所述寄存器中,所述驱动器400通过读取所述寄存器中的第一对应信息来提供预充电电压的电压值。可以理解的是,所述寄存器可以为多个,可将同一条数据线上的多个储存电容的对应关系分组存在不同的寄存器中,例如将临近驱动器一端的寄存器记为第1个寄存器,可将第1个至第10个储存电容的对应关系储存在第1个寄存器中,将第11个至第20个储存电容的对应关系储存在第2个寄存器中,依次类推。所述驱动器400分别从对应的寄存器中读取对应的第一对应信息来提供预充电电压的电压值。
可以理解的是,当任意一个存储电容310被提供的所述预充电电压的电压值相等时,所述第n距离和所述第n预充电时间之间的对应信息形成第二对应信息,所述第二对应信息储存在所述驱动器中。所述驱动器400读取所述第二 对应信息,并根据所述第二对应信息为所述第n储存电容提供预充电电压的充电时间。
在进一步的实施例中,所述像素驱动电路300包括开关薄膜晶体管320,所述第n像素驱动电路300a中的所述开关薄膜晶体管320记为第n开关薄膜晶体管320a,所述第n开关薄膜晶体管320a用于控制所述数据线100与所述第n储存电容310a的导通与截止。
当所述驱动器400提供所述第n充电电压给所述第n储存电容310a时,所述第n开关薄膜晶体管320a导通。在同一条数据线100上的其他所述开关薄膜晶体管320截止。也就是说,同一条数据线100上的每一个储存电容310是在不同时间段内完成充电过程的。当驱动器400对第n储存电容310a充电时,其他的储存电容310不充电。通过开关薄膜晶体管320来控制储存电容310的充电顺序,以使储存电容310更有序完成充电过程。
在进一步的实施例中,所述扫描线200连接所述开关薄膜晶体管320,所述扫描线200用于提供扫描信息,所述扫描信息为导通信息或者截止信息。当所述扫描信息为导通信息时,所述开关薄膜晶体管320导通。当所述扫描信息为截止信息时,所述开关薄膜晶体管320截止。当所述开关薄膜晶体管320为N型晶体管时,所述导通信息为高电平,所述截止信息为低电平。当所述开关薄膜晶体管320为P型晶体管时,所述导通信息为低电平,所述截止信息为高电平。
在进一步的实施例中,所述第n储存电容310a被提供所述第n充电电压的起始时间为第n起始时间,所述第n-1储存电容310b被提供所述第n-1充电电压的起始时间为第n-1起始时间,所述第n-1距离小于所述第n距离,所述第n起始时间早于所述第n-1起始时间。也就是,扫描线200从远离所述驱动器400的一端开始扫描。
在进一步的实施例中,所述导通信息控制所述第n开关薄膜晶体管320a导通的时间记为第n时间,所述第n时间等于所述第n-1起始时间减去所述第n起始时间。当扫描线是在连续时间内扫描第n储存电容310a和第n-1储存电容时310b,所述预设时间即为所述第n时间。
请参阅图2,本发明实施例还提供一种显示装置20,所述显示装置20包括上述任一项实施例所述的显示面板10。所述显示装置20可以为但不仅限于为电子书、智能手机(如Android手机、iOS手机、Windows Phone手机等)、平板电脑、柔性掌上电脑、柔性笔记本电脑、移动互联网设备(MID,Mobile Internet Devices)或穿戴式设备等,或者可以为有机电致发光二极管(Organic light-emitting diodes,OLED)显示装置、有源矩阵有机发光二极管(Active Matrix Organic Light Emitting Diode,AMOLED)显示装置。
