Description

显示面板光学补偿装置、显示面板和显示面板光学补偿方法 技术领域
本发明的实施例涉及一种显示面板光学补偿装置、显示面板和显示面板光学补偿方法。
背景技术
无论是有源矩阵有机发光二极体(Active Matrix/Organic Light Emitting Diode，AMOLED)电视机还是AMOLED显示模组，都存在显示不均匀的问题，即存在显示器亮度不均匀导致各种痕迹的现象Mura。通过光学测量方式即可看到显示器亮度的均匀性比较差。
AMOLED是电流型发光器件，因此受电流的影响很大。由于当前工艺的限制，背板均匀性很难做到让人满意，所以出现了电流的非均匀性。电流的非均匀性会造成亮度的非均匀性，因此导致AMOLED显示器的显示不均匀。
另外，电激发光(Electro Luminescent，EL)工艺有蒸镀型和喷墨打印型等几种，也会造成OLED的电学特性的非均匀性，这种非均匀性同样会造成屏幕显示的不均匀。
为了改善AMOLED显示面板的均匀性，通常会采用一些补偿技术，来缩小屏幕的亮度差异。补偿技术中的外部补偿技术相当于一种反馈机制。图1是AMOLED补偿技术中的补偿反馈机制示意图。在该补偿技术中，先检测出显示面板的不均匀程度，形成数据，该数据相当于对应显示面板的历史档案，反应这个显示面板的物理属性。然后，将数据传递到图像数据处理单元，并由图像数据处理单元进行图像数据的矫正处理。将显示面板原本偏亮位置的图像数据的灰阶降低，形成新的图像数据，再传递出去；将显示面板原本偏暗位置的图像数据的灰阶抬高，形成新的图像数据，再传递出去。这种处理思路类似于电路里面的负反馈设计，将输出端信息反向传送给输入端，借此纠正输入端信息，最终达到动态平衡。
光学补偿技术是外部补偿中的一种。AMOLED光学补偿装置利用光学 CCD设备拍摄点亮的AMOLED显示面板，获得每个像素的亮度数据。然后，该装置对获得的亮度数据进行处理分析，形成芯片能够调用的可烧录数据。然后，该装置将数据烧录到闪存(flash)芯片上。再次开机时需更换另外一套程序，如图2所示，该程序能够读取闪存(flash)芯片存储的数据，并将其存储在同步动态随机存储器(Synchronous Dynamic Random Access Memory，SDRAM)当中。在屏幕正常工作时，随时读取SDRAM中的数据，用以处理输入的图像数据，形成补偿后的数据，传递给AMOLED显示面板。

本发明的实施例的显示面板光学补偿装置可以通过时序控制单元3连接到AMOLED面板，向AMOLED面板输出补偿后的显示数据，以实现显示数据负反馈的光学补偿输出，从而在AMOLED面板上得到补偿后的显示画面。
本发明的实施例还提供了一种显示面板，其包括如上任一项所述的显示面板光学补偿装置。
本发明的实施例的显示面板例如可以为：电子纸、手机、平板电脑、电视机、显示器、笔记本电脑、数码相框、导航仪等任何具有显示功能的产品或部件。
本发明的实施例提供的显示面板光学补偿装置可以为多种形式，只要具有上述单元、组件即可。本领域技术人员可以采用硬件、软件、固件或三者的结合来实现上述单元、组件，从而形成本发明实施例的装置和显示面板。
本发明的实施例还提供了一种光学补偿方法，使用如上任一项所述的显示面板光学补偿装置，所述方法包括以下步骤。
步骤501：将开关置于第一位置，时序控制单元运行在无补偿模式，数据单元接收补偿数据并将该补偿数据烧录至存储单元内。
步骤502：将开关置于第二位置，所述时序控制单元运行在补偿模式，时序控制单元读取存储单元中的补偿数据，对要在显示面板上显示的显示数据进行补偿运算，输出补偿后的显示数据。
下面以一种显示面板光学补偿方法的操作步骤为例，来详细说明本发明实施例的具体实现过程。
步骤601：在电路板上安装闪存芯片，形成电路结构。
本步骤中，在原始出厂状态下，可以将闪存芯片(Flash芯片)直接打件到电路板上。所述闪存芯片作为存储单元，内部的数据为随机数据，即无效数据。
步骤602：将双刀双掷开关置于第一位置，TCON芯片(时序控制单元)在无补偿模式下工作，与闪存芯片无数据交换；CON接口(数据单元)通过CCD获取显示面板不均匀程度信息以得到补偿数据，并将补偿数据烧录至闪存芯片内。
图5和7分别示出了本实施例的显示面板光学补偿方法所使用的显示面板光学补偿装置在无补偿模式下与补偿模式下的连接示意图。如图5和7所示，7为控制和数据总线，双刀双掷开关4配置为分别切换TCON芯片3的工作模式和闪存芯片1的电源。
在初始运行时，首先将双刀双掷开关4置于第一位置，使得第一刀使TCON芯片(时序控制单元)3和第一电平输出端连接，第二刀使Flash芯片(存储单元)1与CON接口(数据单元)2连接。如图5中所示，TCON芯片3通过双刀双掷开关4接地，状态控制信号为Low，参见图6的状态控制信号时序控制图的t1时刻，代表在无补偿模式下工作。Flash芯片1直接连接CON接口2。状态控制信号为Low时，TCON芯片3在与Flash芯片1相连的控制和数据总线7上输出高阻态，将Flash芯片1的控制权交给CON接口2。这样，Flash芯片1的电源由CON接口提供，由于CON接口除了图中所示连接外没有任何其它连接，因此Flash芯片1没有供电。
然后，启动CCD以获取显示面板的不均匀程度信息。然后，处理单元6对该不均匀程度信息进行分析校正，计算负反馈信息，形成补偿数据，并将所述补偿数据传送至CON接口。
CON接口2通过下载线与处理单元6相连。在无补偿模式下，Flash芯片1的控制和数据总线与CON接口连接，并且Flash芯片1的电源由CON接口提供，此时通过计算机(PC)将CON接口接收到的补偿数据烧录至Flash芯片内，覆盖掉原始出厂状态下的随机数据。
步骤603：将双刀双掷开关置于第二位置，令TCON芯片在补偿模式下工作，读取闪存芯片中的补偿数据，进行补偿运算，输出补偿后的数据。
本步骤中，将双刀双掷开关4切换到第二位置，使得第一刀使TCON芯片与第二电平输出端连接，第二刀使闪存芯片和电源连接。如图7所示，TCON芯片3通过双刀双掷开关连接至从TCON芯片接出的高电平输出端，即TCON芯片输出的电源VDD，状态控制信号变为High，见图6中的t2时刻，代表时序控制单元，即TCON芯片在补偿模式下工作。Flash芯片直接连接从TCON芯片引出的电源VDD，由其供电。
此时，CON接口和计算机之间的下载线断开，时序控制单元在补偿模式下运行，TCON芯片自Flash芯片中读取数据，并进行补偿运算，然后输出补偿后的数据至AMOLED面板，得到补偿后的显示画面。
至此，则完成了本发明实施例的显示面板光学补偿方法的全过程。
在本发明的实施例提供的显示面板光学补偿装置、显示面板和显示面板光学补偿方法中，可以通过开关的控制使时序控制单元运行在两种模式。在无补偿模式下，将补偿数据烧录至存储单元内；在补偿模式下，读取补偿数据对显示数据进行补偿，输出补偿后的显示数据。本发明的实施例无需重新开机进行模式切换，装置结构简单，操作灵活，稳定性高，节拍速度快，适合量产。
以上实施例仅用以说明本发明的技术方案，而非对其限制；尽管参照前述实施例对本发明进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本发明各实施例技术方案的精神和范围。
