图 2为根据本发明实施例的电子设备中的亚像素单元的示意图。 具体实施方式
为使本发明的目的、技术方案和优点更加清楚, 下面将结合附图及具体 实施例对本发明进行详细描述。
〈实施例一〉
本发明实施例提供了一种电子设备,用于在釆集物品图像的同时显示该 图像。该电子设备包括至少一个显示单元、和至少一个图像釆集单元,其中, 所述显示单元与所述图像釆集单元相邻排布, 而在所述图像釆集单元中设置 有用于釆集光信号的透镜。

其中, 所述显示单元 111具体可以是有机发光二极管显示单元。 这里, 个相邻的所述显示单元可以由红色、 蓝色和绿色的有机发光层排列形成。
与现有技术类似, 本实施例的上述结构还可以包括图像处理单元(图中 未示出), 用以根据各个图像釆集单元获得的电信号, 生成对应的图像信号, 并控制各个亚像素单元的显示输出信号, 以在该显示面板上显示对应的图 像。
本发明实施例釆用以上结构, 在图像釆集单元中增加了透镜, 从而可以 汇聚光信号以实现距离显示面板更远的物品的图像釆集,提高了现有技术中 的 CM0S-0LDE显示设备所支持的图像釆集距离, 能够获得更好的成像效果。
上述透镜 113具体可以是光学微透镜(或者是光学微透镜组)。 为了实 现远近不同的各种物品的图像釆集, 本实施例可以釆用具有两种以上的不同 焦距的透镜, 分别设置在各个图像釆集单元中, 这样至少存在两个图像釆集 单元具有不同的焦距的透镜。 通过设置具有不同焦距的光学微透镜, 使得图 像釆集单元能够釆集不同距离范围的物品图像的釆集, 进而通过图像处理单 元的进一步处理, 能够获得不同距离的物品的清晰图像。
作为另一种优选实施方式, 本实施例中, 上述透镜 113的焦距可以根据 预定条件进行调节。 例如, 釆用向列型液晶 (NLC )材料形成可调式液晶透 镜(LensVector ), 这种可调式液晶透镜通过在透明的 IT0电极之间釆用了 特殊的控制机制,在在电场作用下通过控制分子结构发生变化进而控制光信 号发生改变, 例如分子结构变化凸透镜形状, 可让光信号汇聚、 实现对焦光 信号等处理。 当电场发生变化时, 可使该材料内部的分子结构发生变化, 从 而可以实现类似于不同焦距的光信号微透镜的效果。

基于以上所述的电子设备,本发明实施例还提供了一种电子设备的成像 方法, 所述方法包括:
步骤 21 , 获得所述至少一个图像釆集单元所釆集到的光信号。
步骤 22 , 基于所述光信号生成图像。
这里可以通过光敏二极管实现光信号到电信号的转换,进而由图像处理 单元基于所述电信号生成图像。
