为使本公开实施例的目的、技术方案和优点更加清楚，下面将结合本公开实施例的附图，对本公开实施例的技术方案进行清楚、完整地描述。显然，所描述的实施例是本公开的一部分实施例，而不是全部的实施例。基于所描述的本公开的实施例，本领域普通技术人员在无需创造性劳动的前提下所获得的所有其他实施例，都属于本公开保护的范围。
除非另作定义，此处使用的技术术语或者科学术语应当为本公开所属领域内具有一般技能的人士所理解的通常意义。本公开中使用的“第一”、“第二”以及类似的词语并不表示任何顺序、数量或者重要性，而只是用来区分不同的组成部分。同样，“一个”、“一”或者“该”等类似词语也不表示数量限制，而是表示存在至少一个。“包括”或者“包含”等类似的词语意指出现该词前面的元件或者物件涵盖出现在该词后面列举的元件或者物件及其等同，而不排除其他元件或者物件。
目前，通过在液晶显示装置的显示液晶面板和背光模组之间设置控光面板可以对提供给显示液晶面板的背光的亮度进行分区域控制。例如，控光面板通常为控光液晶面板，通过调节控光液晶面板的液晶层中液晶分子的偏转角度可以对提供给显示液晶面板的背光的亮度进行调节。例如，通过调节控光液晶面板中液晶分子的偏转角度可以减小向显示液晶面板中对应显示画面的暗态区域的部分提供的背光的亮度，以降低显示画面中暗态区域的透过光强，从而避免或减弱液晶显示装置的暗态漏光现象。
通常情况下，液晶显示装置中的显示液晶面板和控光液晶面板具有相同的外观尺寸及功能尺寸，例如显示液晶面板与控光液晶面板的形状及大小均相同，显示液晶面板中的显示区域与控光液晶面板中的控光区域的形状及大小均相同，以使对位贴合显示液晶面板和控光液晶面板后，控光区域可以与 显示区域相对应，从而背光模组发出的背光在经控光区域调控之后被提供至显示区域。
图1A为一种将显示液晶面板和控光液晶面板进行对位贴合的示意图。例如，如图1A所示，显示液晶面板11包括显示区域12，控光液晶面板13包括控光区域14，显示区域12与控光区域14的形状及大小(即图中二者彼此平行的面(水平面)上的各个方向上的尺寸)均相同。
例如，如图1A所示，显示液晶面板11和控光液晶面板13上均设置有多个对应的对位标记15，以用于在将显示液晶面板11和控光液晶面板13贴合的过程中进行对位，从而实现显示区域12的中心C1与控光区域14的中心C2以及显示区域12和控光区域14在水平面的各个方向上的侧边的对齐。例如，将显示液晶面板11和控光液晶面板13按照对应的对位标记15进行对位后，显示区域12的中心C1和控光区域14的中心C2之间的连线垂直于显示液晶面板11的主表面和控光液晶面板13的主表面，且显示区域12和控光区域14在水平面的各个方向上的侧边在显示液晶面板11的主表面(或控光液晶面板13的主表面)的正投影彼此重叠。由此，在将显示液晶面板11和控光液晶面板13贴合后，控光区域14的中心C2在显示液晶面板11上的正投影可以与显示区域12的中心C1重合，进而使控光区域14在显示液晶面板11上的正投影与显示区域12重合，从而可以通过控光区域14对显示区域12接收的背光的亮度进行调节。
但是，在对位贴合的过程中，由于例如设备精度或工艺精度等方面的影响，显示液晶面板11和控光液晶面板13之间往往会存在贴合偏差，因而在实际制备的液晶显示装置中，控光区域14和显示区域12之间在彼此平行的面中会发生偏移。图中的对位标记为十字形，但是本公开对此不作限制，本公开的实施例可以采用各种适当的对位标记。
例如，如图1B所示，在将显示液晶面板11和控光液晶面板13贴合后形成的液晶显示装置10中，由于贴合偏差的影响，控光区域14的中心C2在显示液晶面板11上的正投影与显示区域12的中心C1没有完全重合，控光区域14在显示液晶面板11上的正投影只能与一部分的显示区域12交叠，即，在垂直于显示液晶面板11(或控光液晶面板13)的主表面的方向上，部分显示区域12没有与控光区域14交叠，从而导致该部分显示区域12无法接收到经控光区域14调节后的背光以执行显示操作，或者接收到相对于预期亮度降低的背光，进而使液晶显示装置10的实际显示区域减小，造成显示区域面积的损失。因而，在液晶显示装置10中，由于显示区域面积的损失，显示画面会出现部分缺失，难以提供完整的显示画面，进而严重降低画面的显示质量以及显示效果，使产品的信赖性和稳定性大大降低。
本公开至少一个实施例提供一种显示装置，该显示装置通过对控光面板 的尺寸设计进行优化，可以降低或避免显示装置中显示区域面积的损失，进而在通过控光面板使显示装置提供的显示画面的对比度提升的基础上，进一步改善画面的显示效果以及显示质量，提升产品的信赖性和稳定性，使用户获得更好的观赏体验。
本公开至少一个实施例提供一种显示装置，该显示装置包括控光面板和显示液晶面板。显示液晶面板位于控光面板的出光侧。控光面板包括控光区域，控光区域被配置为向显示液晶面板提供调节后的背光。显示液晶面板包括显示区域，显示区域被配置为接收调节后的背光以执行显示。控光区域在至少一个方向上的两相对边缘之间的距离大于显示区域在该至少一个方向上的两相对边缘之间的距离。
由于控光区域在至少一个方向上的两相对边缘之间的距离大于显示区域在该方向上的两相对边缘之间的距离，因此该方向上，控光区域的宽度大于显示区域的宽度，从而在将控光面板和显示液晶面板对位贴合后，可以至少在该方向上减弱或避免由于贴合偏差而对显示装置的实际显示区域造成的面积损失。由此，在通过控光面板对显示装置提供的显示画面的亮度进行更加有效地控制以提升画面对比度的同时，可以提高显示装置提供的显示画面的完整性和准确性，从而改善画面的整体显示效果和显示质量，提升产品的信赖性和稳定性，使用户获得更好的观赏体验。
在本公开一些实施例提供的显示装置中，通过使控光区域在至少一个方向上的两相对边缘之间的距离大于显示区域在该方向上的两相对边缘之间的距离，可以在该方向上使显示液晶面板的显示区域在控光面板上的正投影位于控光区域内，进而避免了由于贴合偏差而对显示装置的实际显示区域造成的面积损失，保证了显示装置提供的显示画面的完整性和准确性，从而显著地改善了画面的显示效果以及显示质量，进一步提升了产品的信赖性和稳定性。
下面，将参考附图详细地说明本公开的一些实施例。应当注意的是，不同的附图中相同的附图标记将用于指代已描述的相同的元件。
图2为本公开一些实施例提供的一种显示装置的结构示意图，例如为显示装置20沿第一方向R1的截面结构的示意图。
例如，如图2所示，显示装置20包括显示液晶面板21和控光面板22，显示液晶面板21位于控光面板22的出光侧。控光面板22包括控光区域202，控光区域202被配置为向显示液晶面板21提供调节后的背光。显示液晶面板21包括显示区域201，显示区域201被配置为接收调节后的背光以执行显示。控光区域202在第一方向R1上的两相对边缘230和240之间的距离L22大于显示区域201在第一方向R1上的两相对边缘210和220之间的距离L21。该第一方向R1可以为显示液晶面板21(或控光面板22)所在平面中 的任一方向，例如，当显示液晶面板21的显示区域为矩形时，该第一方向R1可以为该矩形的长边方向、短边方向或对角方向等。
控光区域202在第一方向R1上的两相对边缘230和240之间的距离L22(即控光区域202在第一方向R1上的宽度L22)与显示区域201在第一方向R1上的两相对边缘210和220之间的距离L21(即显示区域201在第一方向R1上的宽度L21)之间的差值大于零，从而可以至少在该第一方向R1上减弱或避免由于贴合偏差而对显示装置20的实际显示区域造成的面积损失。
例如，在图2所示的实施例的至少一个示例中，控光区域202在第一方向R1上的两相对边缘230和240之间的距离L22与显示区域201在第一方向R1上的两相对边缘210和220之间的距离L21之间的差值为预定距离，该预定距离的数值等于在将显示液晶面板21与控光面板22贴合的情形下，显示液晶面板21与控光面板22在第一方向R1上的最大贴合公差的绝对值Xmax1的两倍，即该预定距离的数值为2×Xmax1。
需要说明的是，上述贴合公差指的是在例如利用对位标记(未示出)将显示液晶面板21与控光面板22对位贴合时，由于例如设备精度或工艺精度等方面的原因而允许存在的偏差量的范围，例如在第一方向R1上的贴合公差为显示液晶面板21与控光面板22之间在第一方向R1上的偏差量的范围；相对于完全对齐的状态，该偏差量的范围为-Xmax1～+Xmax1。例如，该偏差量的范围也可以理解为控光区域202的中心A2在显示液晶面板21上的正投影与显示区域201的中心A1之间产生的偏移量。
例如，贴合公差的具体取值范围可以根据显示液晶面板21及控光面板22的尺寸规格、所使用的贴合设备、采用的贴合工艺以及实际不同的操作环境等而确定，该贴合公差的范围需要涵盖在对位贴合显示液晶面板21和控光面板22时由于设备精度、工艺精度等方面的误差而可能产生的最大偏差量，也即控光区域202的中心A2在显示液晶面板21上的正投影与显示区域201的中心A1之间可能出现的最大偏移量。
例如，如图2所示，在显示装置10中的显示液晶面板21和控光面板22贴合后出现偏差且在第一方向R1上的偏差量的大小为X1的情形，也即控光区域202的中心A2在显示液晶面板21上的正投影与显示区域201的中心A1之间在第一方向R1上的偏移量的大小为X1的情形，由于控光区域202在第一方向R1上的宽度L22大于显示区域201在第一方向R1上的宽度L21且大于的差值为2×Xmax1，因此在显示装置20中，显示区域201的边缘210在控光面板22上的正投影与相邻的控光区域202的边缘230之间的距离为Xmax1+X1，显示区域201的边缘220在控光面板22上的正投影与相邻的控光区域202的边缘240之间的距离为Xmax1-X1。由于Xmax1≥X1，因 此在第一方向R1上，显示区域201在控光面板22上的正投影可以位于控光区域202内，也即，在第一方向R1上，显示装置20的实际显示区域的宽度等同于显示区域201的宽度，从而避免了在第一方向R1上由于贴合偏差而对显示装置20的实际显示区域造成的面积损失，提升了显示装置20提供的显示画面的完整性和准确性。
例如，在本公开的一些实施例中，控光区域202在第一方向R1上的两相对边缘230和240之间的距离L22(即控光区域202在第一方向R1上的宽度)与显示区域201在第一方向R1上的两相对边缘210和220之间的距离L21(即显示区域201在第一方向R1上的宽度)之间的差值的大小还可以大于在将显示液晶面板21与控光面板22贴合的情形下，显示液晶面板21与控光面板22在第一方向R1上的最大贴合公差的绝对值Xmax1的两倍，即上述预定距离的数值还可以大于2×Xmax1，从而可以进一步保证显示装置20的实际显示区域在第一方向R1上的宽度，以避免在第一方向R1上对显示装置20的实际显示区域造成面积损失。
例如，在实际情况中，由于设备或实际操作环境的差异，难以准确地确定显示液晶面板21与控光面板22在第一方向R1上的最大贴合公差的绝对值Xmax1，因此通过使上述预定距离的数值大于2×Xmax1，可以进一步保证在第一方向R1上，显示区域201在控光面板22上的正投影可以位于控光区域202内，从而更有效地避免了由于贴合偏差而导致显示装置20在第一方向R1上实际显示区域面积的损失。
例如，如图2所示，显示液晶面板21还包括围绕显示区域201的第一遮光区域203，第一遮光区域203在控光面板22上的正投影在第一方向R1上与控光区域202至少部分重叠。例如，该遮光区域203可以避免或减弱显示区域201中靠近边缘210的部分和靠近边缘220的部分受到多余的光线的干扰。
例如，如图2所示，控光面板22还包括围绕控光区域202的第二遮光区域204。例如，在控光面板22与显示液晶面板21的形状及尺寸相同的情形，第一遮光区域203的面积与第二遮光区域204的面积之间的差值等于控光区域202的面积与显示区域201的面积之间的差值。
例如，如图2所示，显示装置20还包括背光源23。背光源23位于控光面板22远离显示液晶面板21的一侧，且被配置为向控光面板22提供初始背光。控光面板22对初始背光进行调节以得到调节后的背光，并将调节后的背光提供给显示液晶面板21。由此，显示装置20可以通过控光面板22对提供的显示画面的亮度进行更加有效地控制，例如可以降低显示画面中暗态区域的透过光强，从而避免或减弱显示装置20的暗态漏光现象，进而提升画面的对比度，改善画面的显示质量以及显示效果。
需要说明的是，本公开的实施例对背光源23的类型不作限制，例如背光源23包括多个光源，例如多个线光源或由多个点状光源组成，例如点光源可以为LED光源，线光源可以为CCFL光源等；例如，背光源23可以为直下式背光源或侧入式背光源等，侧入式背光源还包括导光板；并且，根据需要，背光源23还可以包括扩散膜、棱镜膜等光学功能膜，本公开的实施例对此不作限制。
例如，背光源23的结构及设置方式可以参考本领域中的常规设计，本公开的实施例对此不作限制。
需要说明的是，图2所示的显示装置20还可以包括其他结构或膜层，例如，在至少一个实施例中，显示装置20还可以包括设置于显示液晶面板21与控光面板22之间的各向同性扩散膜(isotropic diffusion film,IDF)或其他功能性膜层或结构，本公开的实施例对此不作限制。
需要说明的是，显示液晶面板21和控光面板22的具体结构可以参考本领域的常规设计方案，本公开的实施例对此不作限制。例如，显示液晶面板21可以包括例如栅线、数据线、像素电极、公共电极、液晶层和彩膜等用于显示的各种部件等；并且，显示液晶面板21可以为各种类型，例如，垂直电场型或水平电场型，对于水平电场型，可以为面内开关型(IPS)、边缘电场开关型(FFS)或高级超维开关(ADS)型。控光面板22可以包括例如栅线、数据线、像素电极、公共电极、液晶层等用于实现光控的各种部件等；类似地，控光面板22也可以为各种类型，例如，垂直电场型或水平电场型，对于水平电场型，可以为面内开关型(IPS)、边缘电场开关型(FFS)或高级超维开关(ADS)型。
例如，在本公开实施例提供的显示装置20中，控光面板22可以为控光液晶面板，也可以为其他类型的具有光控功能的面板，例如，电子墨水面板或电致变色面板等。
需要说明的是，在图2所示的显示装置20中，仅示出了在第一方向R1上显示区域201的两相对边缘210和220之间的距离L21与控光区域202的两相对边缘230和240之间的距离L22之间的差值关系。显示装置20中其他方向上显示区域201的两相对边缘之间的距离与控光区域202的两相对边缘之间的距离之间的差值关系可以参考上述内容进行设置，在此不再赘述。
例如，根据显示液晶面板和控光面板的实际规格、贴合工艺所能达到的精度标准等不同的实际情况，在本公开一些实施例提供的显示装置中，仅需在一个方向上(例如第一方向R1上)使控光区域的宽度大于显示区域的宽度，例如大于的数值可以为大于或等于该方向上的最大贴合偏差的绝对值的2倍，以使显示区域在控光面板上的正投影可以位于控光区域内。而在本公开一些实施例提供的显示装置中，则需要在多个方向(例如包括第一方向 R1)上使控光区域的宽度大于显示区域的宽度，例如大于的数值可以为大于或等于该方向上的最大贴合偏差的绝对值的2倍，以使显示区域在控光面板上的正投影可以位于控光区域内。
例如，根据显示液晶面板和控光面板的实际规格、贴合工艺所能达到的精度标准等不同的实际情况，在本公开一些实施例提供的显示装置中，可以在某个或某几个方向上将控光区域的宽度与显示区域的宽度之间的差值的大小设置为等于或稍大于该方向上的最大贴合偏差的绝对值的2倍，而在其他方向上将控光区域的宽度与显示区域的宽度之间的差值的大小设置为大于该方向上的最大贴合偏差的绝对值的2倍。也就是说，显示装置中不同方向上的控光区域的宽度与显示区域的宽度之间的差值的大小可以分别确定，本公开的实施例对此不作限制。
需要说明的是，在本公开实施例提供的显示装置中，对显示液晶面板和显示区域的形状或大小、以及相应的控光面板和控光区域的形状或大小不作限制。例如，显示液晶面板和控光面板的形状及尺寸可以彼此相同，或者控光面板的尺寸也可以稍大于显示液晶面板的尺寸。例如，显示区域和控光区域的形状可以相同，也可以不同。
下面以显示液晶面板和控光面板的形状以及显示区域和控光区域的形状均为方形为例，对图2所示的显示装置20的平面结构进行说明。
图3为本公开一些实施例提供的一种显示装置的平面示意图，例如为图2所示的显示装置20的平面结构的示意图。
例如，结合图2和图3所示，显示区域201在第一方向R1上的两相对的第一显示边缘(即边缘210和220)之间的距离L21与控光区域202在第一方向R1上的两相对的第一控光边缘(即边缘230和240)之间的距离L22之间的差值为第一预定距离，该第一预定距离的数值等于在将显示液晶面板21与控光面板22贴合的情形下，显示液晶面板21与控光面板22在第一方向R1上的最大贴合公差的绝对值Xmax1的两倍，即L22-L21＝2×Xmax1。显示区域201在第二方向R2上的两相对的第二显示边缘之间的距离L23与控光区域202在第二方向R2上的两相对的第二控光边缘之间的距离L24之间的差值为第二预定距离，该第二预定距离的数值等于在将显示液晶面板21与控光面板22贴合的情形下，显示液晶面板21与控光面板22在第二方向R2上的最大贴合公差的绝对值Xmax2的两倍，即L24-L23＝2×Xmax2。
例如，结合图2和图3所示，在显示装置20中的显示液晶面板21和控光面板22贴合后出现偏差且在第一方向R1上的偏差量的大小为X1、在第二方向R2上的偏差量的大小为X2的情形，也即控光区域202的中心A2在显示液晶面板21上的正投影与显示区域201的中心A1之间在第一方向R1上的偏移量的大小为X1且在第二方向R2上的偏移量的大小为X2的情形， 由于控光区域202在第一方向R1上的宽度L22大于显示区域201在第一方向R1上的宽度L21且大于的差值为2×Xmax1，因此在显示装置20中，显示区域201的边缘210在控光面板22上的正投影与相邻的控光区域202的边缘230之间的距离为Xmax1+X1，显示区域201的边缘220在控光面板22上的正投影与相邻的控光区域202的边缘240之间的距离为Xmax1-X1。相应地，由于控光区域202在第二方向R2上的宽度L24大于显示区域201在第二方向R2上的宽度L23且大于的差值为2×Xmax2，因此在显示装置20中，显示区域201在第二方向R2上的两相对边缘与相邻的控光区域202在第二方向R2上的两相对边缘之间的距离分别为Xmax2+X2和Xmax2-X2。
由于Xmax1≥X1且Xmax2≥X2，因此在第一方向R1和第二方向R2上显示区域201在控光面板22上的正投影均可以位于控光区域202内，也即显示区域201在控光面板22上的正投影位于控光区域202内。因此，在第一方向R1和第二方向R2上，显示装置20中实际显示区域的宽度均等同于显示区域201的宽度，从而避免了由于贴合偏差而对显示装置20的实际显示区域造成的面积损失，保证了显示装置20提供的显示画面的完整性和准确性，从而显著地改善了画面的显示效果以及显示质量，进一步提升了产品的信赖性和稳定性。
例如，在图3所示的实施例中，以显示区域201和控光区域202的形状为方形为例进行说明，即第一方向R1垂直于第二方向R2。而在本公开的其他一些实施例中，根据显示区域201和控光区域202的实际不同形状，例如显示区域201和控光区域202的形状也可以为梯形、菱形等，第一方向R1和第二方向R2之间的角度关系也随之相应地调整。
例如，在本公开的一些实施例中，控光区域202在第一方向R1上的两相对边缘之间的距离(即控光区域202在第一方向R1上的宽度L22)与显示区域201在第一方向R1上的两相对边缘之间的距离(即显示区域201在第一方向R1上的宽度L21)之间的差值的大小还可以大于在将显示液晶面板21与控光面板22贴合的情形下，显示液晶面板21与控光面板22在第一方向R1上的最大贴合公差的绝对值Xmax1的两倍，即L22-L21＞2×Xmax1。控光区域202在第二方向R2上的两相对边缘之间的距离(即控光区域202在第二方向R2上的宽度L24)与显示区域201在第二方向R2上的两相对边缘之间的距离(即显示区域201在第二方向R2上的宽度L23)之间的差值的大小还可以大于在将显示液晶面板21与控光面板22贴合的情形下，显示液晶面板21与控光面板22在第二方向R2上的最大贴合公差的绝对值Xmax2的两倍，即L24-L23＞2×Xmax2。由此，可以进一步保证显示装置20的实际显示区域在第一方向R1和第二方向R2上的宽度，以避免对显示装置20的实际显示区域造成面积损失。
例如，在实际情况中，由于设备或实际操作环境等的差异，难以分别准确地确定显示液晶面板21与控光面板22在第一方向R1上的最大贴合公差的绝对值Xmax1以及在第二方向R2上的最大贴合公差的绝对值Xmax2。因此通过使第一预定距离和第二预定距离的数值分别大于2×Xmax1以及2×Xmax2，可以进一步保证显示区域201在控光面板22上的正投影位于控光区域202内，从而更有效地避免了由于贴合偏差而导致显示装置20的实际显示区域面积的损失。
例如，在本公开的一些实施例中，控光面板包括控光像素阵列，控光像素阵列被配置为对射入控光面板的背光进行调节，以使控光面板向显示液晶面板提供调节后的背光。该控光像素阵列至少位于控光区域中。
例如，在本公开的一些实施例中，显示液晶面板的显示区域包括阵列排布的多个显示像素单元，例如显示像素阵列。例如，显示装置通过位于控光区域中的控光像素阵列对显示像素阵列中的多个显示像素单元所接收到的背光的亮度进行分区域调节。
下面以图2和图3所示的显示装置20的结构为例，对显示装置20中控光像素阵列的结构设计进行说明。
图4为本公开一些实施例提供的一种显示装置中控光像素阵列与显示像素阵列的示意图，例如为图2和图3所示的显示装置20中控光像素阵列与显示像素阵列的示意图。
例如，结合图3和图4所示，显示装置20的显示区域201包括阵列排布的多个显示像素单元410。显示装置20的控光像素阵列包括阵列排布的多个控光像素单元420。
例如，在显示装置20的控光面板22中，第二遮光区域204至少部分遮挡控光像素阵列在第一方向R1和第二方向R2上位于控光区域202的边缘的控光像素单元420以形成控光区域202。例如，如图4所示，控光像素阵列中位于第一方向R1和第二方向R2上的边缘的控光像素单元420的一部分位于控光区域202中，一部分被第二遮光区域204遮挡。
例如，在图3和图4所示的显示装置20中，显示液晶面板21的第一遮光区域(未示出)对显示液晶面板21中除显示区域201以外的部分进行遮挡，例如第一遮光区域可以在垂直于显示液晶面板21的主表面的方向上，对控光区域202中未与显示区域201交叠的部分进行遮挡，进而以避免位于该部分区域内的控光像素单元420对显示区域201中的显示像素单元410接收的背光的亮度造成干扰。
例如，在显示装置20的实际显示区域中，每个控光像素单元420分别与一部分显示区域201内的多个显示像素单元410对应，进而可以分区域调节显示区域201内的显示像素单元410所接收的背光的亮度。
例如，在图4所示的实施例中，控光像素阵列中的多个控光像素单元420均具有相同的结构设计，从而可以降低显示装置20的制备成本以及制备工艺的难度。例如，可以根据控光区域202在第一方向R1上的宽度L22和在第二方向R2上的宽度L24来确定控光像素单元420的个数，以使控光像素阵列在第一方向R1上的尺寸等于或稍大于L22且在第二方向R2上的尺寸等于或稍大于L24。例如，控光像素阵列位于控光区域202以外的部分可以通过第二遮光区域204中设置的例如黑矩阵(或遮光层)进行遮挡，从而形成控光区域202。
图5为本公开一些实施例提供的另一种显示装置中控光像素阵列与显示像素阵列的示意图，例如为图2和图3所示的显示装置20中控光像素阵列与显示像素阵列的示意图。
例如，结合图3和图5所示，显示装置20的显示区域201包括阵列排布的多个显示像素单元410。控光像素阵列位于控光区域202中，控光像素阵列包括边缘控光像素单元430和中部控光像素单元440，边缘控光像素单元430沿控光区域202的边缘设置且围绕中部控光像素单元440。在至少一个方向上，例如在第一方向R1或第二方向R2上，边缘控光像素单元430的尺寸不同于中部控光像素单元440的尺寸。
例如，相比于图4中所示的控光像素阵列，图5中所示的控光像素阵列中的边缘控光像素单元430和中部控光像素单元440分别具有不同的结构设计，进而可以使控光像素阵列在第一方向R1上的尺寸和在第二方向R2上的尺寸分别等于控光区域202在第一方向R1上的宽度L22和第二方向R2上的宽度L24。由此，显示装置20的第二遮光区域204中无需设置控光像素阵列，进而可以对第二遮光区域204中的结构设计以及面积大小进行更灵活地调整和优化。
例如，在图5所示的显示装置20中，沿控光区域202在第一方向R1上的边缘的边缘控光像素单元430在第二方向R2上的尺寸均不同于中部控光像素单元440在第二方向R2上的尺寸，例如可以稍大于中部控光像素单元440在第二方向R2上的尺寸。沿控光区域202在第二方向R2上的边缘的边缘控光像素单元430在第一方向R1上的尺寸均不同于中部控光像素单元440在第一方向R1上的尺寸，例如可以稍小于中部控光像素单元440在第一方向R1上的尺寸。
需要说明的是，在图5所示的显示装置20中，位于不同位置的边缘控光像素单元430与中部控光像素单元440在第一方向R1以及第二方向R2上的尺寸关系只是示例性说明。例如，在本公开的其他一些实施例中，边缘控光像素单元430与中部控光像素单元440在第一方向R1以及第二方向R2上的尺寸关系可以根据显示区域201和控光区域202在第一方向R1和第二 方向R2上的宽度进行设置，本公开的实施例对此不作限制。
需要说明的是，在图5所示的显示装置20中，边缘控光像素单元430的设计结构只是示例性说明；在本公开的其他一些实施例中，边缘控光像素单元430的设计结构可以根据例如控光区域202的轮廓形状、大小等进行设置，本公开的实施例对此不作限制。
例如，图4中所示的控光像素单元420以及图5中所示的边缘控光像素单元430和中部控光像素单元440的具体结构和排布方式等可以参考本领域中的常规设计，本公开的实施例对此不作限制。
需要说明的是，图4和图5中所示的控光像素阵列和显示像素阵列只是示例性说明。例如，本公开实施例对控光像素阵列中的控光像素单元以及显示像素阵列中的显示像素单元的个数、具体结构、排布方式等不作限制。
例如，在本公开一些实施例提供的显示装置中，以图4和图5所示的显示装置20为例，显示液晶面板21和控光面板22在第一方向R1和第二方向R2上的最大贴合公差的绝对值Xmax1和Xmax2通常分别小于显示像素单元410在第一方向R1和第二方向R2上的尺寸。由此，在显示液晶面板21和控光面板22出现贴合偏差的情形下，显示装置20中的控光像素单元(例如控光像素单元420、边缘控光像素单元430和中部控光像素单元440)和显示像素单元410之间不会出现对应异常，因而可以保证显示装置20中画面的正常显示。
需要说明的是，在本公开实施例提供的显示装置中，显示液晶面板的每个显示像素单元包括至少一个子像素单元，即包括至少一个子像素，例如图4和图5中所示的为每个显示像素单元410包括3个子像素单元且3个子像素单元沿第一方向R1并列排布的情形。本公开实施例对每个显示像素单元中设置的子像素单元的具体个数、排布方式等不作限制，显示像素单元的结构、功能等可以参考本领域中的常规设计方案，在此不再赘述。
例如，在本公开一些实施例提供的显示装置中，根据不同实际情况的需求，在显示装置在至少一个方向上的贴合公差的绝对值大于或等于显示像素单元在该方向上的尺寸的情形，由于显示画面中一般不存在灰阶突变的情况，例如通常情况下，相邻的显示像素单元对应的背光亮度基本相同或相似，因而在显示装置中的控光像素单元和显示像素单元之间出现轻微对应异常的情形，显示装置仍旧可以提供相对正常的显示画面。
例如，在本公开一些实施例提供的显示装置中，根据目前贴合工艺中通常存在的最大贴合公差的数值，控光区域在至少一个方向上的两相对边缘之间的距离与显示区域在该至少一个方向上的两相对边缘之间的距离之间的差值的最小取值范围例如可以为400～600微米，进一步可以为200～400微米。
例如，在本公开一些实施例提供的显示装置中，由于贴合公差的具体取 值范围需要根据例如显示液晶面板和控光面板的尺寸规格、所使用的贴合设备、采用的贴合工艺以及实际不同的操作环境等条件而确定，因此，在相对难以准确确定最大贴合公差的数值的情形，显示液晶面板与控光面板之间的尺寸关系还可以根据显示液晶面板中显示像素单元的尺寸而进行设置。
例如，在本公开一些实施例提供的显示装置中，显示区域包括阵列排布的多个显示像素单元，控光区域在至少一个方向上的两相对边缘之间的距离与显示区域在该至少一个方向上的两相对边缘之间的距离之间的差值为预定距离，该预定距离的数值大于等于显示像素单元在至少一个方向上的尺寸。
例如，对于大小为61寸的方形显示装置，显示像素单元的宽度通常为372微米，相应地，控光区域在该宽度方向上的两相对边缘之间的距离与显示区域在该宽度方向上的两相对边缘之间的距离之间的差值可以设置为大于等于372微米或370微米。例如，对于大小为55寸的方形显示装置，显示像素单元的宽度通常为315微米，相应地，控光区域在该宽度方向上的两相对边缘之间的距离与显示区域在该宽度方向上的两相对边缘之间的距离之间的差值可以设置为大于等于315微米或320微米。
例如，本公开实施例提供的显示装置中的控光面板可以为控光液晶面板或其他具有控光功能的面板。本公开实施例提供的显示装置可以为液晶显示装置或其他具有显示功能的装置。
例如，在本公开一些实施例提供的显示装置中，控光面板还包括第一栅极驱动电路，第一栅极驱动电路位于第二遮光区域内且位于控光区域的至少一侧。第一栅极驱动电路包括多个级联的第一移位寄存器单元，多个第一移位寄存器单元分别与控光像素阵列中的多行控光像素单元电连接以提供第一栅极驱动信号。第一移位寄存器单元包括第一晶体管，第一晶体管包括并列排布的多个有源层，例如包括两行并列排布的有源层。
由于在控光面板和显示液晶面板的移位寄存器单元中，起到相同或相似作用的晶体管(例如输出晶体管、输入晶体管、复位晶体管等)的尺寸基本相同，例如晶体管的长度和宽度基本相同，因此通过将控光面板的第一移位寄存器单元中的第一晶体管的有源层排布为多行(例如排布为两行)且通过第一晶体管的源极和漏极串联，可以根据不同实际需求，对第一移位寄存器单元在不同方向上所占的尺寸进行适应性调整，从而优化控光面板的第二遮光区域内的布局设计，进而简化显示装置的制备工艺。
例如，以图3所示的显示装置20为例，控光面板22的第二遮光区域204内的第一移位寄存器单元中的第一晶体管的有源层包括如图6所示的沿第二方向R2并列排布的两行有源层AL，每行有源层AL包括多个沿第一方向R1并列排布且彼此相连的U型结构，两行有源层AL通过第一晶体管的例 如源极SE和漏极DE串联，从而可以减小第一移位寄存器单元在第一方向R1上所占的尺寸。由此，当第二遮光区域204在第一方向R1上的宽度小于第一遮光区域203在第一方向R1上的宽度时，通过减小控光面板22的第一移位寄存器单元在第一方向R1上所占的尺寸且增加第一移位寄存器单元在第二方向R2上所占的尺寸，可以优化控光面板22的第二遮光区域204内的布局结构，进而简化显示装置20的制备工艺。
例如，在本公开的一些实施例中，第一移位寄存器单元还可以包括多个将有源层排布为多行(例如两行、三行或更多行)的晶体管，从而可以进一步对第一移位寄存器单元在不同方向上所占的尺寸进行适应性调整，优化控光面板的第二遮光区域内的布局设计。
图7为本公开一些实施例提供的一种第一移位寄存器单元的具体实现示例的电路图。
例如，如图7所示，第一移位寄存器单元500包括输出电路510、输出复位电路520、输入电路530和降噪电路540。
例如，输入电路530包括第三晶体管M3。第三晶体管M3的栅极与第一极连接且配置为和输入端INT连接以接收输入信号，第三晶体管M3的第二极配置为和第一节点N1连接。第三晶体管M3配置为响应于输入信号将输入信号写入第一节点N1，以控制第一节点N1的电平。
例如，输出电路510包括第一晶体管M1，第一晶体管M1包括两行并列排布的有源层，例如如图6所示的通过例如源极SE和漏极DE串联的两行有源层AL。第一晶体管M1的栅极和第一节点N1连接，第一晶体管M1的第一极和时钟信号端CLK连接以接收时钟信号，第一晶体管M1的第二极和输出端OUTP连接。例如，第一晶体管M1配置为接收时钟信号并在第一节点N1的电平的控制下将时钟信号输出至输出端OUTP以作为第一栅极驱动信号。
例如，输出电路510还包括第一电容C1。第一电容C1的第一极配置为和第一节点N1连接，第一电容C1的第二极配置为和输出端OUTP连接。
例如，输出复位电路520包括第二晶体管M2，第二晶体管M2包括两行并列排布的有源层，例如如图6所示的通过例如源极SE和漏极DE串联的两行有源层AL。第二晶体管M2的栅极和复位端RST连接以接收复位信号，第二晶体管M2的第一极和输出端OUTP连接，第二晶体管M2的第二极和第一电压端VSS(例如提供低电平电压)连接。第二晶体管M2配置为响应于复位信号将例如低电平电压施加至输出端OUTP，以对输出端OUTP进行复位。
例如，降噪电路540包括第四晶体管M4。第四晶体管M4的栅极和复位端RST连接以接收复位信号，第四晶体管M4的第一极和第一节点N1连 接，第四晶体管M4的第二极和第一电压端VSS连接。第四晶体管M4配置为响应于复位信号将例如低电平电压施加至第一节点N1，以进行降噪。
例如，在上述示例中，第一晶体管M1为输出电路510中起到输出作用的晶体管，即输出晶体管；第二晶体管M2为输出复位电路520中起到复位输出端作用的晶体管，即输出复位晶体管。通常，由于为了保证充电率，第一移位寄存器单元500中的输出晶体管或输出复位晶体管的有源层的尺寸往往较大，在使用单个或单行设置的有源层的情形，第一移位寄存器单元500在某一方向上所占的尺寸可能会较大。例如，以图3所示的显示装置20为例，当输出晶体管或输出复位晶体管的有源层沿第一方向R1单行设置时，第一移位寄存器单元500在第一方向R1上可能会需要占据第二遮光区域204内较多的空间。例如，输出晶体管(即第一晶体管M1)的沟道长度可以为几千微米，而大尺寸高分辨率的电视产品中的输出晶体管的尺寸甚至会大于10000微米。并且，由于输出复位晶体管(即第二晶体管M2)用于放电，因而输出复位晶体管的有源层的尺寸往往也会较大。因此，采用包括两行并列排布的有源层的第一晶体管M1和第二晶体管M2分别作为输出晶体管和输出复位晶体管可以优化控光面板的第二遮光区域内的布局结构，进而简化显示装置的制备工艺。
需要说明的是，图7所示的4T1C的电路结构只是示例性说明，在本公开的其他一些实施例中，控光面板的第一移位寄存器单元也可以采用其他类型的电路结构，例如6T1C、17T1C、19T1C等。本公开的实施例对此不作限制。
需要说明的是，在图7所示的第一移位寄存器单元500中，包括两行并列排布的有源层的第一晶体管和第二晶体管分别为输出晶体管和输出复位晶体管，而在本公开的其他一些实施例中，根据不同实际需求，电路结构中的其他晶体管的有源层也可以设置为两行(或更多行)并通过晶体管的源极和漏极串联，本公开的实施例对此不作限制。
需要说明的是，第一电容C1可以是通过工艺制程制作的电容器件，例如通过制作专门的电容电极来实现电容器件，该电容的各个电极可以通过金属层、半导体层(例如掺杂多晶硅)等实现，并且，第一电容C1也可以是晶体管之间的寄生电容，可以通过晶体管本身与其他器件、线路来实现。
需要说明的是，第一节点N1并非表示实际存在的部件，而是表示电路图中相关电连接的汇合点。
需要说明的是，第一移位寄存器单元500采用的晶体管均可以为薄膜晶体管、场效应晶体管或其他特性相同的开关器件，本公开的实施例以薄膜晶体管为例进行说明。这里采用的晶体管的源极、漏极在结构上可以是对称的，所以其源极、漏极在结构上可以是没有区别的。在本公开的实施例中，为了 区分晶体管除栅极之外的两极(即源极和漏极)，直接描述了其中一极为第一极，另一极为第二极。在本公开的实施例中的晶体管均以N型晶体管为例进行说明，此时，晶体管的第一极是漏极，第二极是源极。需要说明的是，本公开包括但不限于此。例如，本公开的实施例提供的移位寄存器单元500中的一个或多个晶体管也可以采用P型晶体管，此时，晶体管第一极是源极，第二极是漏极，只需将选定类型的晶体管的各极参照本公开的实施例中相应晶体管的各极相应连接，并且使相应的电压端提供对应的高电压或低电压即可。当采用N型晶体管时，可以采用氧化铟镓锌(Indium Gallium Zinc Oxide，IGZO)作为薄膜晶体管的有源层，相对于采用低温多晶硅(Low Temperature Poly Silicon，LTPS)或非晶硅(例如氢化非晶硅)作为薄膜晶体管的有源层，可以有效减小晶体管的尺寸以及防止产生漏电流。
例如，在本公开一些实施例提供的显示装置中，显示液晶面板还包括第二栅极驱动电路，第二栅极驱动电路位于第一遮光区域内且位于显示区域的至少一侧。第二栅极驱动电路包括多个级联的第二移位寄存器单元，多个第二移位寄存器单元分别与显示区域中的多行显示像素单元电连接以提供第二栅极驱动信号。第一移位寄存器单元中包括的晶体管的个数大于第二移位寄存器单元中包括的晶体管的个数。
由于在控光面板和显示液晶面板的移位寄存器单元中，起到相同或相似作用的晶体管(例如输出晶体管、输入晶体管、复位晶体管等)的尺寸基本相同，例如晶体管的长度和宽度基本相同，因此在第一移位寄存器单元内包括的晶体管的数量较多时，将第一移位寄存器单元中的一个或多个晶体管的有源层排布为两行(或多行)可以使第一移位寄存器单元和第二移位寄存器单元在某一方向上的尺寸基本保持一致，进而可以根据实际不同需求对显示装置的布局设计进行优化，简化显示装置的制备工艺。
例如，在本公开一些实施例提供的显示装置中，控光面板的第一移位寄存器单元可以采用19T1C的电路结构，显示液晶面板的第二移位寄存器单元采用17T1C的电路结构。
例如，在本公开一些实施例提供的显示装置中，控光面板的第一移位寄存器单元的行高小于一行控光像素单元的行高，即沿第一晶体管的多行(例如两行)有源层的排布方向，第一移位寄存器单元所占的尺寸小于一行控光像素单元的行高。第一移位寄存器单元通过信号线与对应的一行控光像素单元电连接，信号线为折线型。
图8A为本公开一些实施例提供的一种第一栅极驱动电路的第一移位寄存器单元与控光像素单元之间的连接方式的示意图，图8B为本公开一些实施例提供的一种第二栅极驱动电路的第二移位寄存器单元与显示像素单元之间的连接方式的示意图。
例如，以图4所示的显示装置20为例，结合图4和图8A所示，控光面板22的第一栅极驱动电路包括多个级联的第一移位寄存器单元(例如，第N行、第N+1行、第N+2行、第N+3行、第N+4行第一移位寄存器单元等，N为大于0的整数)，多行第一移位寄存器单元分别与控光像素阵列中的多行控光像素单元(例如，第N行、第N+1行、第N+2行、第N+3行、第N+4行控光像素单元等)电连接以提供第一栅极驱动信号。例如，第N行第一移位寄存器单元与第N行控光像素单元电连接以提供第N行控光像素单元所需的第一栅极驱动信号。
需要说明的是，图8A中没有示出多个第一移位寄存器单元之间的级联关系，上下两行第一移位寄存器单元之间的具体级联方式可以参照本领域中的常规设计，本公开实施例对此不作限制。
例如，控光面板22的第N行第一移位寄存器单元的行高H1(即第N行第一移位寄存器单元在第二方向R2上所占的尺寸)小于第N行控光像素单元的行高H2，即H1<H2，因此连接第N行第一移位寄存器单元和第N行控光像素单元的信号线L10需要为折线型，例如呈蛇形延伸。
例如，信号线L10的至少一个弯折处可以设置为直角，进而减弱在制备过程中工艺波动的影响，优化控光面板22的制备过程，提升制备的控光面板22的稳定性。或者，在本公开的其他一些实施例中，根据不同的实际布局需求，信号线L10的弯折处还可以设置为其他角度，或者信号线L10还可以设置为其他适合的形状，本公开的实施例对此不作限制。
例如，连接多行第一移位寄存器单元和多行控光像素单元的多条信号线在第一方向R1上所占的尺寸大致相同，也即每行信号线在第一方向R1上的长度彼此大致相同。例如，以第N行信号线L10为例，第N行信号线L10在第一方向R1上的长度为L101。
例如，结合图4和图8B所示，显示液晶面板21的第二栅极驱动电路包括多个级联的第二移位寄存器单元(例如，第M行、第M+1行、第M+2行、第M+3行、第M+4行第二移位寄存器单元等，M为大于0的整数)，多行第二移位寄存器单元分别与显示像素阵列中的多行显示像素单元(例如，第M行、第M+1行、第M+2行、第M+3行、第M+4行显示像素单元等)电连接以提供第二栅极驱动信号。例如，第M行第二移位寄存器单元与第M行显示像素单元电连接以提供第M行显示像素单元所需的第二栅极驱动信号。
需要说明的是，图8B中没有示出多个第二移位寄存器单元之间的级联关系，上下两行第二移位寄存器单元之间的具体级联方式可以参照本领域中的常规设计，本公开实施例对此不作限制。
例如，显示液晶面板21的第M行第二移位寄存器单元的行高H3(即 第M行第二移位寄存器单元在第二方向R2上所占的尺寸)等于第M行显示像素单元的行高H4，即H3＝H4，因此连接第M行第二移位寄存器单元和第M行显示像素单元的信号线L20可以呈直线延伸。
本公开至少一个实施例还提供一种控光面板，该控光面板包括控光区域。控光面板被配置为向位于控光面板的出光侧的显示液晶面板提供调节后的背光。显示液晶面板包括显示区域，显示区域被配置为接收调节后的背光以执行显示。控光区域在至少一个方向上的两相对边缘之间的距离大于显示区域在该至少一个方向上的两相对边缘之间的距离。
本公开至少一实施例提供的控光面板的控光区域在至少一个方向上的两相对边缘之间的距离大于显示区域在该方向上的两相对边缘之间的距离，即控光面板的控光区域至少在一个方向上的宽度大于显示区域的宽度，从而在将控光面板与对应的显示液晶面板对位贴合后，可以在至少一个方向上减弱或避免由于贴合偏差而对显示液晶面板的实际显示区域造成的面积损失。由此，在通过控光面板对显示液晶面板中的显示画面的亮度进行更加有效地控制以提升画面对比度的同时，可以提高显示液晶面板中显示画面的完整性和准确性，从而改善画面的整体显示效果和显示质量，提升产品的信赖性和稳定性，使用户获得更好的观赏体验。
例如，在本公开至少一个实施例提供的控光面板中，控光区域在至少一个方向上的两相对边缘之间的距离与显示区域在至少一个方向上的两相对边缘之间的距离之间的差值为预定距离，该预定距离的数值大于等于在将显示液晶面板与控光面板贴合的情形下，显示液晶面板与控光面板在至少一个方向上的最大贴合公差的绝对值的两倍。
例如，在本公开至少一个实施例提供的控光面板中，控光区域在任一方向上的两相对边缘之间的距离均大于显示区域在任一方向上的两相对边缘之间的距离。因此，在将控光面板与对应的显示液晶面板对位贴合后，显示液晶面板的显示区域在控光面板上的正投影可以位于控光区域内，进而避免了由于贴合偏差而对显示液晶面板的实际显示区域造成的面积损失，保证了提供的显示画面的完整性和准确性，从而显著地改善了画面的显示效果以及显示质量，进一步提升了产品的信赖性和稳定性。
例如，本公开实施例提供的控光面板的具体结构及功能可以参考本公开实施例提供的显示装置中关于控光面板的描述，例如可以参考上述显示装置20的实施例中关于控光面板22的描述，在此不再赘述。

例如，在本公开至少一个实施例提供的制备方法中，对位贴合控光面板和显示液晶面板包括：使得显示区域在控光面板上的正投影位于控光区域内。
例如，在本公开至少一个实施例提供的制备方法中，控光区域在至少一个方向上的两相对边缘之间的距离与显示区域在至少一个方向上的两相对边缘之间的距离之间的差值为预定距离，该预定距离的数值大于等于该对位贴合在上述至少一个方向上的最大贴合公差的绝对值的两倍。
本公开实施例提供的显示装置的制备方法的具体说明及效果可以参考本公开实施例提供的显示装置中的相应内容，例如可以参考上述显示装置20的实施例中的相应内容，在此不再赘述。
本公开至少一个实施例还提供一种电子设备，该电子设备包括本公开实施例提供的任意一种显示装置，例如可以包括上述实施例中的显示装置20。
例如，该电子设备可以为显示基板、显示面板、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，本公开的实施例对此不作限制。
