Description

一种显示面板的驱动方法和驱动电路
【技术领域】
本发明涉及液晶显示领域, 更具体的说, 涉及一种显示面板的驱动方法和 驱动电路。
【背景技术】
目前液晶显示器的解析度和尺寸越来越大型化, 以薄膜型晶体管 (TFT)为主 要驱动方式的面板对应的等效传输途径上的等效电阻和电容负载越来越大, 如 图 1 所示, 数据驱动集成电路 (Data IC)在第一条扫描信号到来时候输出数据信 号, 波形如图 2所示; 而第 n条扫描线位置的数据信号会变异成如图 3所示的 波形, 这种变异通常业界叫做 RC延时, 这样对同一条数据线来说, 在不同的 垂直位置会有不同的充电效果, 严重时会造成上、 下和中心均齐度差异较大, 看到的影像品味较差。
【发明内容】
本发明所要解决的技术问题是提供一种能减少均齐度差异的显示面板的驱 动方法和驱动电路。
本发明的目的是通过以下技术方案来实现的:
一种显示面板的驱动方法, 包括步骤:
逐行驱动显示面板的扫描线;
其中在一帧画面显示的时间内, 至少有一条扫描线的驱动时间大于第一条 扫描线的驱动时间;
在一帧的周期内, 所有扫描线的驱动时间总和不超过单帧显示时间。
进一步的, 假设第一条扫描线的驱动时间为 T, 扫描线总数为 N, 相邻两帧 画面的垂直空白时间为 T1 , 所有扫描线驱动时间之和为 Tm, 则 Tm与 T X N的 差值小于或等于 Tl。经研究,相邻两个帧图像切换的时候存在垂直空白(vertical blanking ) 时间, 该时间内显示面板无画面显示。 据此, 本技术方案将垂直空白 时间计入单帧显示时间内, 只要扫描线累计增加的时间不超过垂直空白时间, 就不会影响正常的画面显示。 本方案增加了扫描线的充电时间, 可以在改善均 齐度的基础上提高像素的充电率。
进一步的, 在一帧画面显示的时间内, 下一行扫描线的驱动时间大于上一 行扫描线的驱动时间。
进一步的, 在一帧画面显示的时间内, 相邻两条扫描线驱动时间的差值相 等。 差值相等方便设计;
进一步的, 在一帧画面显示的时间内, 相邻两条扫描线驱动时间的差值递 增。 采用递增方案均齐度的平衡效果更佳, 因为随着数据线长度的增加, 在 RC 延时的作用下, 其信号波形的变异不是线性变化的, 而是呈现递增趋势。 因此 扫描线的驱动时间的增加也采用递增的方案, 可以更好地补偿波形的变异, 显 示效果更佳。
进一步的, 将扫描线进行分组, 每组扫描线至少包括一条扫描线; 下一组 扫描线的驱动时间大于上一组扫描线的驱动时间。 分组控制有利于筒化控制方 案, 降低开发和制作成本。
进一步的, 每组内的扫描线驱动时间相等。
进一步的, 在一帧画面显示的时间内, 相邻两组扫描线驱动时间的差值相 等。
一种显示面板的驱动电路, 包括扫描线, 所述扫描线连接有控制扫描线驱 动时序的时间模块;
所述时间模块逐行驱动显示面板的扫描线;
其中在一帧画面显示的时间内, 至少有一条扫描线的驱动时间大于第一条 扫描线的驱动时间;
假设第一条扫描线的驱动时间为 T,扫描线总数为 N,相邻两帧画面的垂直 空白时间为 T1 , 所有扫描线驱动时间之和为 Tm, 则 Tm与 T x N的差值小于或 等于 Tl。
进一步的, 所述驱动电路包括与扫描线连接的扫描线驱动模块, 所述时间 模块包括与扫描线驱动模块耦合的时序控制器、 与时序控制器耦合的存储单元; 时序控制器从存储单元读取每行扫描线的驱动时间, 生成驱动信号发送到 扫描线驱动电路。
进一步的, 所述驱动电路包括与扫描线连接的扫描线驱动模块, 所述时间 模块包括时序控制器和存储单元, 时序控制器包括逐行增加扫描线驱动时间的 驱动单元;
驱动单元从存储单元读取相邻两条扫描线驱动时间的差值, 生成驱动信号 发送到扫描线驱动电路。
现有每条扫描线的驱动时间是相等的, 因此随着数据信号传输距离的增加, 在相同的扫描线驱动时间内, 像素的充电量递减, 从而造成均齐度差异。 本发 明采用增加扫描线驱动时间的方式来延长数据线的充电时间, 补偿因为电阻电 容引起的数据信号波形变异(RC delay ) 而造成充电效果差异, 达到亮度均匀, 提高产品的均齐度, 改善品味性的目的, 只要驱动所有扫描线的累计时间不超 过单帧的显示时间, 就不会影响正常的画面显示。 采用本发明的技术方案无需 改变现有的数据驱动信号, 仅需要调整相对筒单的扫描线驱动时序即可, 有利 于缩减开发周期, 减低开发难度。

本发明公开了一种显示面板的驱动方法和驱动电路。 该驱动电路包括扫描 线, 所述扫描线连接有控制扫描线驱动时序的时间模块;
所述时间模块逐行驱动显示面板的扫描线;
其中在一帧画面显示的时间内, 至少有一条扫描线的驱动时间大于第一条扫 描线的驱动时间;
在一帧的周期内, 所有扫描线的驱动时间总和不超过单帧显示时间。
现有每条扫描线的驱动时间是相等的, 因此随着数据信号传输距离的增加, 在相同的扫描线驱动时间内, 像素的充电量递减, 从而造成均齐度差异。 本发 明采用增加扫描线驱动时间的方式来延长数据线的充电时间, 补偿因为电阻电 容引起的数据信号波形变异( RC delay )而造成的充电效果差异,达到亮度均匀, 提高产品的均齐度, 改善品味性的目的, 只要驱动所有扫描线的累计时间不超 过单帧的显示时间, 就不会影响正常的画面显示。 采用本发明的技术方案无需 改变现有的数据驱动信号, 仅需要调整相对筒单的扫描线驱动时序即可, 有利 于缩减开发周期, 减低开发难度。
下面结合附图和较佳的实施例对本发明作进一步说明。
实施例一
如图 4所示, 本实施方式公开一种显示面板的驱动方法, 包括步骤:
51、 设定第一行扫描线的驱动时间 T;
52、 根据相邻两帧画面的垂直空白时间 T1和扫描线的总数 N计算每条扫描 线驱动时间的增值 Δ Τ;
53、 逐行驱动显示面板的扫描线; 先驱动上一行扫描线;
54、 再驱动下一行扫描线; 在一帧画面显示的时间内, 下一行扫描线的驱动 时间大于上一行扫描线的驱动时间, 且相邻两条扫描线驱动时间的差值都为 Δ T; 假设第一条扫描线的驱动时间为 T, 扫描线总数为 Ν, 相邻两帧画面的垂直 空白时间为 T1 , 所有扫描线驱动时间之和为 Tm, 则 Tm与 T x N的差值小于或 等于 Tl。
经研究, 相邻两个帧图像切换的时候存在垂直空白(vertical blanking )时间, 该时间内显示面板无画面显示。 据此, 本技术方案将垂直空白时间计入单帧显 示时间内, 只要扫描线累计增加的时间不超过垂直空白时间, 就不会影响正常 的画面显示。 本方案增加了扫描线的充电时间, 可以在改善均齐度的基础上提 高像素的充电率。
以解析度为 1920X1080(水平显示像素 X 垂直显示像素),其水平总像素: 2200, 垂直总像素: 1125 , 扫描频率: 60HZ为例, 其 vertical blanking (垂直空 白)时间大约有 0.7ms,每行的扫描时间大约是 14.8us, 可以通过某种方式让其每 行的打开时间从一个基准值开始逐渐调整每行的充电时间, 直到最大的扫描时 间允许数值, 如图 5所示, 第一条开启长度 14.2us开始, 大约经历 1080行后以 14.8us结束一个 frame (帧)的充电, 接着周而复始。 这样可以让液晶面板的上, 中, 下各区域的充电程度和液晶面板的开始端保持尽量一致, 达到预期目的。
进一步的, 为了筒化控制, 可以将扫描线进行分组, 以组为单元进行控制。 每组扫描线至少包括一条扫描线; 下一组扫描线的驱动时间大于上一组扫描线 的驱动时间, 每组内的扫描线驱动时间相等, 且相邻两组扫描线驱动时间的差 值相等。
随着数据线长度的增加, 在 RC延时的作用下, 其信号波形的变异不是线性 变化的, 而是呈现递增趋势。 因此扫描线的驱动时间的增加也可以采用递增的 方案, 能更好地补偿波形的变异, 显示效果更佳。
实施例二
如图 6所示, 本发明公开了一种显示面板的驱动方法和驱动电路。 该驱动电 路包括扫描线 30, 与扫描线 30连接的扫描线驱动模块。 时间模块 10包括时序 控制器 12和存储单元 11 , 时序控制器 12包括逐行增加扫描线驱动时间的驱动 单元 13;
驱动单元 13从存储单元 11读取相邻两条扫描线驱动时间的差值, 生成驱动 信号发送到扫描线驱动电路 20。
假设第一条扫描线的驱动时间为 T, 扫描线总数为 N, 相邻两帧画面的垂直 空白时间为 T1 , 所有扫描线驱动时间之和为 Tm, 则 Tm与 T x N的差值小于或 等于 Tl。
当然, 相邻两条扫描线的驱动时间的差值也可以不等, 此时可以省略驱动单 元 13, 时序控制器 12从存储单元 11读取每行扫描线的驱动时间, 生成驱动信 号发送到扫描线驱动电路 20。
存储单元选用 EEPROM , 当然也可以选用闪存、 ROM等存储器件。
以上内容是结合具体的优选实施方式对本发明所作的进一步详细说明, 不能 认定本发明的具体实施只局限于这些说明。 对于本发明所属技术领域的普通技 术人员来说, 在不脱离本发明构思的前提下, 还可以做出若干筒单推演或替换, 都应当视为属于本发明的保护范围。
