以下将结合附图及实施例来详细说明本发明的实施方式,借此对本发明如何应用技术 手段来解决技术问题,并达成技术效果的实现过程能充分理解并据以实施。需要说明的是, 只要不构成冲突,本发明中的各个实施例以及各实施例中的各个特征可以相互结合,所形 成的技术方案均在本发明的保护范围之内。
如图 2所示,为根据本发明的原理设计的公共电 ]£自动调整系统 200的示意图。在显 示面板 102上划分了多个区域或者称为若干代表性的点 S】、 S2、 ……。 这些区域分别对 应于不同的公共电压驱动输入( Vl、 V2、 ……) 。 例如, 调整 VI或 V2的大小可以改变 S2区域处的闪烁值。 在不同的区域 (S1、 S2、 ……) 附近安装了多个感光器, 以便可以
感测来自不同区域的发光量,从而得到对应于不同区域的闪烁值„感测器将得到的闪烁值 传送到多路复用元件 205。
多路复用元件 205与多个感光器连接。可以接收多个感光器传送的闪烁值,并在一个 时刻选择将其中的一个闪烁值传送给中央处理单元或计算比较单元 202。由于多路复用元 件传送的闪烁值还是个模拟量, 而计算比较单元 202处理的是数字量。 因此, 还需要在其 与计算比较单元 202之间设置模数转换单元 203。
i十算比较单元 202在一个时间序列上连续接牧多路复用元件 205发送的多个传感器感 测的闪烁值, 计算由多个闪烁值确定的实际显示条件, 并将其与最佳显示条件比较, 判断 是否满足所述最佳显示条件。
给显示面板上的不同区域分配不同的权重,并基于该权重计算由多个闪烁值确定的实 际显示条件。如图 3所示, 为显示面板上的不同区域分配的不同权重的示意图。在该示例 中, 可以看出, 面板两侧的区域的权重稍小些, 例如 Wl=0.i , 而面板中央位置的权重最 大, W0=0.6。 因为面板中间的区域在显示中对视觉的影响最大。 当然, 还可以存在其他 分配权重的情况, 这些不同的权重分配均落于本发明的保护范围。
在本发明的一个实施例中, 可以按照以下公式来计算实际的显示条件-
M

公共电压调节输出单元 20 和 204与计算比较单元 202连接。当最佳显示条件不满足 时, 调整当前的公共电压输出值, 如果满足, 保持当前的公共电压输出值不变。
在一个实施例中, 可以以下方式进行电压的调整- 当比较的结果表明实际显示条件与最佳显示条件相差超过第一预设值 ,优先调整权 重值最大的区域对应的公共电压输出值;
当比较的结果表明实际显示条件与最佳显示条件相差小于第二预设值 ,优先调整权 重值最小的区域对应的公共电 i£输出值;
当比较的结果表明实际显示条件与最佳显示条件相差在第一预设值和第二预设值之 闾时, 优先调整权重值处于中间的区域对应的公共电压输出值。
在一个实例中,公共电压调节输出单元 20】和 204包括公共电 ]£缓存器。该缓存器中 设有一块存储区, 其用于 存待输出的公共电压值, 并在输出指令下达时, 将其通过数模 转换后提供给显示面板各个不同区域对应的公共电极端。
如图 4所示,为根据本发明的原理进行自适应多区公共电压调整方法的流程图。该方 法开始于步骤 S401。 并在步骤 S402中, 感测来自不同区域的发光量, 从而得到对应于不 同区域的闪烁值并进行传送。 在步骤 S403中, 接收对应于多个区域的闪烁值, 并在一个 时刻将其中的一个闪烁值进行传送。
在步骤 S404中, 在一个时间序列上连续接收感测的闪烁值, 计算所述多个闪烁值导 致的显示条件, 并将其与最佳显示条件比较, 判断是否满足所述最佳显示条件。
在歩骤 S405中, 判断当所述最佳显示条件不满足时, 调整当前的公共电压值 (在步 骤 S406中实现) , 如果满足, 保持当前的公共电压输出值不变, 并将调整过程结束, 歩 骤 S407。
当比较的结果表明实际显示条件与最佳显示条件相差超过第一预设值 ,优先调整权 重值最大的区域对应的公共电压输出值;
当比较的结果表明实际显示条件与最佳显示条件相差小于第二预设值 ,优先调整权 重值最小的区域对应的公共电压输出值;
当比较的结果表明实际显示条件与最佳显示条件相差在第一预设值和第二预设值之 闾时, 优先调整权重值处于中间的区域对应的公共电压输出值。
上述操作反复执行,直到实际显示条件与最佳显示条件匹配,或者在最佳显示条件附 近的范围内, 可以输出停止调整的指令, 使得公共电压的输出值保持稳定。
显示面板上的不同区域分配不同的权重,并基于该权重计算由所述多个闪烁值确定的 显示条件。在一个例子中,可以通过改变电压缓存器中存储的电压值来调节输出的公共电 压。 也可以通过改变公共电压驱动电路的输入电压值来调节输出的公共电压。
虽然本发明所揭露的实施方式如上,但所述的内容只是为了便于理解本发明而采用的 实施方式, 并非用以限定本发明。任何本发明所属技术领域内的技术人员, 在不脱离本发 明所揭露的精神和范围的前提下,可以在实施的形式上及细节上 ί乍任何的修改与变化,但 本发明的专利保护范围, 仍须以所附的权利要求书所界定的范围为准。
