Abstract:
An electrophoretic display apparatus includes a first substrate, a plurality of sub-pixel structures, a color filter array, and an electrophoretic layer. The sub-pixel structures are disposed on the first substrate, and each of the sub-pixel structures includes a plurality of sub-pixel sub-structures. The color filter array is disposed above the sub-pixel structures, and includes a plurality of filter units. The filter units are divided into a plurality of groups having different colors, and the filter units belonging to the groups having different colors are alternately disposed above the sub-pixel structures. Each of the filter units corresponds to the sub-pixel sub-structures of at least one sub-pixel structure, and at least two of the sub-pixel sub-structures of the same sub-pixel structure are adapted to be applied different voltages. The electrophoretic layer is disposed on the sub-pixel structures.
