[0004] In the existing electronic paper display device, the distribution structure of the pixel electrode 03 is as follows figure 1 As shown, when the black charged particles gather to the block-shaped pixel electrode 03 on the driving substrate under the electronic ink layer, the external light passes through the upper substrate through the transparent electrophoretic liquid, and is reflected by the lower reflective layer 04 to the observation surface, but irradiates to A considerable part of the incident angle of external light on the reflective layer 04 is not in the normal direction of the observation surface, which will cause color mixing of the light displayed between two adjacent pixel units 05, such as figure 2 As shown, that is, the display light of display area 01 enters display area 02, affecting the normal display of display area 02

The invention relates to the technical field of display devices discloses an electronic paper display device and a preparation method thereof and aims at decreasing light mixing phenomena occurred between every two adjacent pixel units and improving the display effect of the electronic paper display device. The electronic paper display device comprises a first substrate provided with a first electrode layer, a second substrate provided with a second electrode layer, an electronic ink layer arranged between the first electrode layer and the second electrode layer and multiple pixel units arranged between the first substrate and the second substrate and arranged in an array mode, wherein the first electrode layer comprises first sub-electrode zones corresponding to the pixel units in a one-to-one mode and distributed along the peripheries of the corresponding pixel units, and each first sub-electrode zone at least surrounds two sides of the corresponding pixel unit.
Description
technical field [0001] The invention relates to the field of display technology, in particular to an electronic paper display device and a preparation method thereof. Background technique [0002] With the rapid development of display technology, many novel display devices have been continuously developed. Among them, electronic paper display devices have many advantages such as low power consumption, thinness, long life, and flexibility, and have great potential for development. [0003] Traditional electronic paper display devices generally use the method of reflecting external ambient light to realize image display, that is, disperse black charged particles in transparent electrophoretic liquid to form an electronic ink layer, and control the distribution of black charged particles on the display viewing surface through the electrode electric field. Realize the display of black / white screen. When the black charged particles are evenly distributed on the upper substrate o...
