example (1

[0148] A ferroelectric PVDF sheet with a thickness of 40 pm was used. TiO 2 The dispersible sheet is laminated on the surface of the PVDF sheet. TiO 2 The dispersible tablet was 10 microns thick with the base tablet material made of polyethylene. This laminate was cut into squares with an average size of 200 μm*200 μm by using a sharp square stainless steel sheet. For the thixotropic suspending medium, 5 centistokes of silicon fluid (Aldrich Chemical Company) and fumed silica flakes were mixed in a weight ratio of 5 to 1. After the two were completely mixed, 5% by weight of the above-prepared PVDF particle excised portion was mixed with the thixotropic fluid. The original PVDF sheet has 15nC / cm 2 spontaneous polarization.

[0149] This mixture forms a very viscous colloidal fluid. In order to stabilize the fluid, after leaving the fluid at room temperature for 24 hours, the fluid was moved to the next step of the experiment. Color filter glass substrates based on both ...

[0157] A ferroelectric PVDF sheet with a thickness of 40pm was used. A carbon based dyed dispersant sheet was laminated on one surface of the PVDF sheet. The carbon disperse sheet is 10 microns thick, where the base sheet material is made of polyethylene. Cut the laminate into squares of average size 200 μm*200 μm by using a sharp square stainless steel sheet. For the thixotropic suspending medium, 5 cmS of silicon fluid (Aldrich Chemical Co.) and fumed silica flakes were mixed in a 5 to 1 weight ratio. After the two were completely mixed, 5% by weight of the above-prepared PVDF particle excised portion was mixed with the thixotropic fluid. The original PVDF sheet has 12nC / cm 2 spontaneous polarization.

[0158] This mixture forms a very viscous colloidal fluid. In order to stabilize the fluid, after leaving the fluid at room temperature for 24 hours, the fluid was moved to the next step of the experiment. Red, blue and green color filters were used together with transpa...

example (3

[0164] A ferroelectric PVDF sheet with a thickness of 40pm was used. The PVDF sheet has its own spontaneous polarization direction perpendicular to the sheet surface, and the same TiO 2 The dispersant sheet is laminated on one surface of the PVDF sheet, which is the negative polarization direction. TiO 2 The dispersible tablet was 10 microns thick with the base tablet material made of polyethylene. The same carbon-based dyed disperse sheet as in Example 2 was laminated on the other surface of PVDF, which was positively charged. Both surfaces of PVDF are laminated with white flakes and black flakes. This laminate was cut into squares with an average size of 200 μm*200 μm by using a sharp square stainless steel sheet. For the thixotropic suspending medium, 5 centistokes of silicon fluid (Aldrich Chemical Company) and fumed silica flakes were mixed in a weight ratio of 5 to 1. After the two were completely mixed, 5% by weight of the excised portion of the PVDF particles prep...

Abstract

New type of electrophoretic display mode is disclosed in this Invention. Introducing transparent medium in an electrophoresis technology, diversity application type of full motion video, full-color image capable electrophoretic display system is realized. New concept of optical switching element based on ferroelectric coupling torque enables both crisp full motion video image and non-power based still image. This display configuration is also effective to apply large billboard displays with significant power saving.

Description

technical field [0001] The present invention relates to an electrophoretic display whose drive torque is derived from a ferroelectrically coupled substrate, and whose specific structure is a reflective type display and a transparent type display. Background technique [0002] Due to the advantages in terms of power consumption and clarity under sunlight ambient brightness conditions, memory type display devices have attracted much research and product consideration since the beginning of the flat panel display industry. Some LCDs are being used for this purpose with their memory functions. Over the past few years, some types of electrophoretic displays have come into widespread use, especially in so-called e-reader displays. [0003] Reflective display technology based on memory function is suitable for display devices, especially for character displays, just like paper-like images. The reflective properties of displayed images are also well suited to replace paper media, ...
