    • A dual-sided electrophoretic display (700) having a first region (701) and a second region (702) is provided. Each of the first region (701) and the second region (702) includes selectively operable members (703,704) that function as pixels for presenting images on the electrophoretic display (700). Each of the selectively operable members (703,704) is driven by a driver circuit (710) by way of corresponding thin film transistors and capacitors (742,742), which are opaque. As the selectively operable members (704) of the second region (702) are bigger than are the selectively operable members (703) of the first region (701), the aperture ratio of the selectively operable members (704) of the second region (702) is greater than in the first region (701) when viewed from the rear side (730). Thus, a contrast ratio of the second region (602), when viewed from the rear side (730) is sufficiently high that text, icons, and characters presented in the second region (602) are legibly visible on the rear side (730).
    • 提供具有第一区域(701)和第二区域(702)的双面电泳显示器(700)。 第一区域(701)和第二区域(702)中的每一个包括用作在电泳显示器(700)上呈现图像的像素的选择性可操作的构件(703,704)。 选择性可操作的构件(703,704)中的每一个由不透明的相应的薄膜晶体管和电容器(742,742)由驱动电路(710)驱动。 由于第二区域(702)的选择性可操作的构件(704)比第一区域(701)的可选择性地操作的构件(703)大,所以第二区域(702)的可选择性地可操作的构件(704) 702)从后侧(730)观察时大于第一区域(701)。 因此,当从后侧(730)观察时,第二区域(602)的对比度足够高,使得呈现在第二区域(602)中的文本,图标和字符在后侧(730)上可见地可见, 。
