Abstract:
일실시예에따른촉각디스플레이장치는제1 전극, 제1 전극상의기둥구조지지체들, 기둥구조지지체들사이의전기활성고분자, 및전기활성고분자상의제2 전극을포함할수 있다. 평면도상에제1 전극과제2 전극이교차하는면 당여섯개의기둥구조지지체들이도시되어있지만, 지지체들의개수에한정되지않는다. 또한기둥의단면이사각형으로한정되지않는다. 외부전압이인가될경우전기활성고분자가수축될수 있다. 예를들어, 전기활성고분자가유전탄성체인경우, 외부전압의크기제곱에비례하여두께방향(z 방향)으로수축될수 있다. 기둥구조지지체들은외부전압및 전기활성고분자의수축에의해변형되지않을수 있다. 따라서, 기둥구조지지체들이삽입된부분은전기활성고분자의상부면및 하부면보다바깥쪽으로더 돌출될수 있다. 또한, 제1 전극및 제2 전극은순응전극이므로돌출된모양을따라서변형될수 있다. 결과적으로, 외부전압인가시촉/질감을제공할수 있는디스플레이장치가얻어질수 있다.
Abstract:
A transistor according to one embodiment of the present invention includes an active layer and a gate insulating layer which touches the active layer. The active layer and the gate insulating layer include the same oxide. The oxygen content of the oxide of the gate insulating layer is higher than the oxygen content of the oxide of the active layer. Because the active layer and the gate insulating layer have the same material, high charge mobility in the active layer is obtained in driving the transistor. In manufacturing the transistor, the active layer and the gate insulating layer are formed by depositing the same material in the same sputtering chamber while changing oxygen partial pressure ratios.

Abstract:
A method for cleaning a flexible substrate is provided to improve the yield of a flexible substrate by guaranteeing process reliability and mass production of a flexible substrate without modifying the mass production equipment of conventional semiconductor and display devices. After a flexible substrate(21) is loaded, impurities attached to both main surfaces of the flexible substrate are detached by adhesive force while using first rotational rollers(22) positioned on both the main surfaces of the flexible substrate. The impurities are transferred from the first roller to rotational second rollers(23) by using the second rollers having high adhesive force as compared with the first roller. The static electricity of the flexible substrate can be removed by using anti-static equipment.

An electrophoretic microcapsule patterning method and an electrophoretic display are provided to manufacture pixels having a desired, uniform line-width by molding iterative patterns on a substrate and applying microcapsule lines between the patterns and to prevent the blur of a color between adjacent colors to improve the quality of the electrophoretic display. A photosensitive film is formed on a substrate(S210). In order to form iterative patterns, the photosensitive film is patterned in a lithography method(S220). A microcapsule slurry, a compound of a microcapsule and a water-soluble binder, is manufactured(S230). The manufactured microcapsule slurry is poured into a dispenser(S240). The microcapsule slurry is applied between the iterative patterns of the photosensitive film(S250).
