Abstract
An electrophoresis display includes a control substrate having a first face and a second face, a driving circuit layer, a control electrode layer, an electrophoresis layer, and an opposite substrate. The viewing face of the electrophoresis display is on the first face of the control substrate. The aperture ratio of the control substrate in the electrophoresis display, viewed from the first face of the control substrate and toward a display area of the electrophoresis display, is not less than 70%.
Claims31
An electrophoresis display, comprising:
- a control substrate, comprising a first face and a second face;
- a driving circuit layer, arranged on the second face of the control substrate and comprising a plurality of thin film transistors, a plurality of gate lines, and a plurality of data lines, at least one of the gate lines electrically connected to gates of the thin film transistors, at least one of the data lines electrically connected to drains or sources of the thin film transistors;
- a control electrode layer arranged on a side of the driving circuit layer away from the control substrate and comprising a plurality of transparent control electrodes, at least one of the transparent control electrodes electrically connected to the source or the drain of one of the thin film transistors;
- an electrophoresis layer comprising an electrophoretic material, the electrophoretic material comprising a plurality of charged color particles, the charged color particles arranged in a colloidal solution and moving through the colloidal solution under an influence of an electric field, the charged color particles comprising positively charged color particles and/or negatively charged color particles;
- and
- an opposite substrate arranged on a side of the electrophoresis layer away from the control substrate;
- wherein, the first face is a viewing face of the electrophoretic display;
- along a direction looking from the first face of the control substrate into a display region of the electrophoretic display, an aperture ratio of the control substrate of the electrophoretic display is not less than 70%.
