Method of producing display panel and display panel
View Patent ↗The prevent invention is a method in which microcapsules are placed at desired locations selectively accurately and easily to produce a high accuracy electrophoretic display panel. In the production method of a display panel of the present invention, the microcapsules ( 43 ) are uniformly coated onto a substrate ( 41 ), on which electrodes ( 42 ) is formed by using an optical hardening resin as a binder material ( 44 ). Next, the binder material ( 44 ) is hardened by selectively irradiating a light beam to the only locations desired for placing the microcapsules ( 43 ) by using a photomask ( 45 ). The binder material ( 44 ) of portions not hardened is removed by washing in water. Thus, the microcapsules can be selectively and accurately placed at the only desired positions. A color electrophoretic display panel, in which each microcapsule of three primary colors is placed in a predetermined arrangement, can be produced by sequentially performing the processes for the three types of microcapsules corresponding to three primary colors.
1. A display apparatus including a plurality of pixels comprising:
a plurality of microcapsules in which a dispersion media and a plurality of particles are sealed therein; and
a binder of optical hardening resin that binds the plurality of microcapsules to each other,
wherein the microcapsules and the binder form a layer that is selectively placed in a region corresponding to the pixels and irradiated by light to harden the binder, and
wherein the plurality of microcapsules provide different colors upon receiving light, and the respective microcapsules for providing the respective colors are arranged on the respective corresponding electrodes.
2. The display apparatus according to claim 1 , wherein the particles include at least one of an electrophoretic or a magneticphoretic particle.
3. The display apparatus according to claim 1 , wherein the dispersion media is colored.
4. The display apparatus according to claim 3 , wherein the plurality of microcapsules include a plurality of groups, the dispersion media of each group is different in color.
5. The display apparatus according to claim 4 , wherein the particles of each group is colored different from the color of the dispersion media.
6. The display apparatus according to claim 3 , wherein the dispersion media is colored with dye(s) and/or pigment(s).
