Problems solved by technology

[0006] However, in a high-temperature and high-humidity environment, when there is peeling between the adhesive layer 111 and the boundary electrode 120, the electric field distribution of the electrophoretic display layer 112 will be uneven, resulting in the frame pattern mura (display blemish) appears

Embodiment Construction

[0023] In order to strengthen the bonding effect of the adhesive layer and avoid mura at the boundary of the viewing area, the boundary structure of the viewing area of ​​the electronic paper display of the present invention produces a plurality of downward protrusions on the lower surface of the adhesive layer. Please refer to image 3 , which shows a partial cross-sectional view of a preferred embodiment of the boundary structure of the visible area of ​​the electronic paper display of the present invention. From the partial cross-sectional view, it can be seen that the composition of the boundary structure of the visible area is a protective layer 200, a front panel 210, a boundary electrode 220, and a flat layer 240 from top to bottom, wherein the composition of the front panel 210 is from the bottom to the bottom. The uppermost layer is an adhesive layer 211 , an electrophoretic display layer 212 , an ITO layer 213 , and a PET layer 214 . When there is a voltage differen...

Abstract

The invention discloses a visible range boundary structure of an electronic paper display. The structure is provided with a flat layer, a boundary electrode, a viscose layer and an electrophoresis display layer, wherein the boundary electrode is located above the flat layer and composed of metal; the viscose layer is located above the boundary electrode, and the lower surface of the viscose layer is provided with at least one downward-protruding part to increase the adhesive force; and the electrophoresis display layer is located on the upper surface of the viscose layer.

Description

technical field [0001] The invention relates to an electronic paper display, in particular to an electronic paper display border structure for reducing the occurrence probability of electronic paper display mura (display defect). Background technique [0002] In order to prevent the pixels around the display area from being covered by the edge strips of the casing, the current electronic paper displays generally reserve a strip-shaped border area around the display area, and respectively set corresponding strip-shaped border electrodes. During operation, the electronic paper display can control the displayed color of the border area by applying a voltage to the strip-shaped border electrodes. Usually, the display color of the boundary area will be set to be similar to the color of the electronic paper display casing—for example, black, so that the boundary area becomes a buffer zone between the display area and the edge of the casing to absorb the width error of the edge of ...
