Example Embodiment

[0067]

[0068] Titanium oxide powder (white particles) with an average particle size of 3μm covered with polyethylene resin and carbon black powder (black particles) with an average particle size of 4μm surface-treated by alkyltrimethylammonium chloride are placed in a transparent dispersion medium. Disperse in vinyl chloride to obtain dispersion A. In this case, the white particles are negatively charged and the black particles are positively charged.

[0069] Next, dissolve gelatin and sodium polystyrene sulfonate in water to prepare an aqueous solution, mix it with Dispersion A, adjust the liquid temperature to 40°C, and stir with a homogenizer while keeping the liquid temperature to obtain an O / W emulsion .

[0070] Next, the obtained O / W emulsion and the aqueous solution in which gum arabic was dissolved in water were mixed using a disperser at 40°C, while maintaining the liquid temperature at 40°C, acetic acid was used to adjust the pH of the solution to 4. A microcapsule ...

Abstract

The invention relates to a color-electrophoresis type display media panel which can ensure excellent display luminance and excellent display quality heterogeneity and can improve the narrow viewing angle. The color-electrophoresis type display media panel comprises a transparent substrate, a color filter layer, a transparent electrode layer, a microcapsule layer, an adhesive laye and a back electrode plate which are overlapped in sequence; the microcapsule layer is directly overlapped on the transparent electrode layer; the average particle diameters in arbitrary direction are defined as X and the average particle diameters in the orthogonal direction are defined as Y in the state of observing the particle diameters of the microcapsule in the microcapsule layer from the observation side; the distribution of the microcapsules with the average particle diameters X is as follows: more than 80% of the microcapsules have the average particle diameters of above X1 (X-20mum) and below X2 (X+20mum), less than 20% of the microcapsules have the average particle diameters of below X1 (X-20mum), and less than 5% of the microcapsules have the average particle diameters of above X2 (X+20mum), wherein the X is 35-45mum; and the distribution of the microcapsules with the average particle diameters of Y is the same as that of the microcapsules with average particle diameters of X.

Description

technical field [0001] The invention relates to a microcapsule electrophoretic display panel integrated with a color filter, and to a color electrophoretic display medium panel, which is composed of a structure in which a microcapsule layer is arranged between a group of opposing electrode plates. The layer is obtained by encapsulating electrophoretic ink in microcapsules, and one of the counter electrode plates is a transparent substrate with a color filter layer, thereby improving image quality. Background technique [0002] In recent years, with the development of information equipment, information display has also taken various forms. As display panels for variable information, CRTs (Cathode Ray Tubes) and liquid crystals using backlights are the mainstream. However, emissive displays such as CRTs and liquid crystal displays using backlights are unsuitable for long-term continuous reading of documents, etc., because the burden on the eyes is heavy and the eyes look tire...
