Double layer superposed electronic paper driving structure

Abstract

The invention provides a double layer superposed electronic paper driving structure. The structure herein is characterized in that: the structure includes an upper layer electronic paper which is a cholesteric liquid crystal electronic paper screen and is composed of a surface glass substrate, a bottom glass substrate, a first driving control chip, a first driving layer FPC, and a liquid crystal and a glue frame which are inside the liquid crystal screen. The first driving control chip is disposed on the bottom glass substrate. The lower electronic paper is an electrophore electronic paper andis composed of an electrophore electronic payer film, a back glass substrate, a second driving control chip and a second driving layer FPC. The second driving control chip is arranged on the back glass substrate. The test interfaces of the upper layer electronic paper / the lower electronic paper are connected to a double layer superposed electronic paper test system plate directly or indirectly through the respective first driving layer FPC / the second driving layer FPC. The periphery of the double layer superposed electronic paper driving structure is sealed with a sealant. According to the invention, the structure herein has the advantages of enhanced display effects, optimized test interfaces, simplified hardware structures and lower cost.

Description

technical field [0001] The invention relates to a double-layer stacked electronic paper driving structure. Background technique [0002] In recent years, as people's visual pursuit of electronic display effects has become higher and higher, the research and application of color electronic paper has gradually attracted more and more people's attention. Generally, the upper / lower layer of electronic paper belongs to two independent and different types of electronic paper, and two sets of test system boards are needed to drive it, which causes defects such as redundant hardware system and unsightly structure. Therefore, it is necessary to provide a The double-layer superimposed electronic paper drive structure integrates the test system into one set to solve the shortcomings of the existing technology. Contents of the invention [0003] According to the technical problem raised above, a double-layer stacked electronic paper driving structure is provided. The present inventi...
