Problems solved by technology

Generally speaking, an electrophoretic display is mainly composed of a thin film transistor array substrate and an electrophoretic display film, and the dielectric layer used to define micro-cups in the electrophoretic display film is made of a light-transmitting material. After the external light source passes through the dielectric layer in the electrophoretic display film, it will irradiate the thin film transistors on the thin film transistor array substrate, causing the thin film transistors to generate photocurrent and affect the characteristics of the elements, resulting in poor display quality of the electrophoretic display

[0030] figure 1 It is a schematic cross-sectional view of the electrophoretic display panel according to the first embodiment of the present invention. Please refer to figure 1 The electrophoretic display panel 100 of this embodiment includes an active device array substrate 110 and an electrophoretic display film 120 . The active device array substrate 110 includes a plurality of active devices 112 and a light shielding layer 114 covering the active devices 112 . The electrophoretic display film 120 is disposed on the active device array substrate 110 , and the electrophoretic display film 120 includes a conductive layer 122 , a dielectric layer 124 and a plurality of electrophoretic display media 126 . Such as figure 1 As shown, the dielectric layer 124 is disposed on the lower surface of the conductive layer 122, the dielectric layer 124 has a plurality of microcups 124a arranged in an array and located on its lower surface, and the dielectric layer 124 is located betwee...

[0036] figure 2It is a schematic cross-sectional view of the electrophoretic display panel according to the second embodiment of the present invention. Please refer to figure 2 , the electrophoretic display panel 100' in this embodiment is similar to the electrophoretic display panel 100 in the first embodiment, but the main difference between them is that the light shielding layer 114 in the active element array substrate 110' in this embodiment is located Between the pixel electrode PE and the active device 112 , and the active device 112 and the pixel electrode PE form a plurality of pixels P. In other words, the light-shielding layer 114 and the pixel electrode PE belong to different film layers, which are different from the reflective pixel electrode R of the first embodiment.

[0037] Based on the above, the light-shielding layer 114 of this embodiment can be a metal layer with a single-layer structure, a metal layer with a multi-layer structure, a light-shielding la...

Abstract

The invention discloses an electrophoretic display panel which comprises an active element array substrate and an electrophoretic display film. The active element array substrate is provided with a plurality of active components and a light shield layer shielding the active elements. The electrophoretic display film is configured on the active element array substrate and comprises a conducting layer, a dielectric layer and a plurality of electrophoretic display media. The dielectric layer is configured on the conducting layer and is provided with a plurality of microcups which are distributed in an array, the dielectric layer is positioned between the conducting layer and the active element array substrate, and the light shield layer prevents light penetrating the dielectric layer from irradiating the active elements. In addition, the electrophoretic display media are configured in the microcups.

Description

technical field [0001] The present invention relates to an electrophoresis display panel, and in particular to an electrophoresis display panel with a light-shielding layer. Background technique [0002] In recent years, due to the continuous vigorous development of various display technologies, after continuous research and development, products such as electrophoretic displays, liquid crystal displays, plasma displays, organic light-emitting diode displays, etc., have been gradually commercialized and applied to various sizes and Display devices of various sizes. With the increasing popularity of portable electronic products, flexible displays (such as electronic paper (e-paper), electronic book (e-book), etc.) have gradually attracted the attention of the market. Generally speaking, electronic paper (e-paper) and electronic book (e-book) use electrophoretic display technology to achieve the purpose of display. Taking an e-book as an example, its sub-pixels are mainly co...
