Abstract:
PURPOSE: A touch screen is provided to minimize reflectivity, thereby reducing external light reflection. CONSTITUTION: The first and second transparent electrode layers(111,112) are mutually separated. Spacers(140) separate the first and second transparent electrode layers. An image display unit(130) is located under of the second transparent electrode layer. An adhesive layer(150) adheres the image display unit and the second transparent electrode layer. A refractive index matching layer(160) is filled between the spacers. The image display unit provides video information in the form of light.
Abstract:
A touch input device and a method for manufacturing the same are provided to integrate a touch sense device and a lighting device. A light source(110) generates light. A PCB(Printed Circuit Board)(120) for light guide comprises a transparent substrate body and one or more electrodes. When the generated light is incident on one side, the transparent substrate body propagates the incident light to the inside. At least one electrode is formed on an upper part of the transparent substrate body. A plurality of concave grooves is formed on a lower surface of the transparent substrate body. The concave grooves refract at least a part of the incident light to the electrode.

A sensor(100) for measuring bio information comprises a light guide plate(110), an optical extracting pattern(120), and an optical coupling pattern(130). The light guide plate guides a first light. The light extracting pattern is formed on the light guide plate, and outputs the first light to outside of the light guide plate by the light guide plate. The light coupling pattern is formed on the light guide plate, change progressive direction of a second light irradiated form the outside of the light guide plate, and guides the second light by the light guide plate.
Abstract:
The method of forming the semiconductor device is provided to prevent the loss of dopant in the thermal process by forming the capping oxide covering the semiconductor substrate in which dopant is injected. The conductive pattern(114) is formed on the semiconductor substrate(100). The photoresist pattern exposing the semiconductor substrate adjacent to the conductive pattern is formed. The dopant is injected by using the conductive pattern and photoresist pattern as mask and then impurity regions (140a,140b) are formed in the semiconductor substrate. The photoresist pattern is removed. The capping oxide covering the semiconductor substrate is formed. The thermal process is performed on the substrate. The dopant is activated.
Abstract:
A key-pad assembly is provided to allow a user to recognize a pushing state of a key button and to select electric contacts from a touch sensor or a switch member. A key-pad assembly includes a key-pad(230), a touch sensor(220), and a switch member(210). The touch sensor includes a light guiding plate(222). The touch sensor is positioned in a lower part of the key-pad and reflects light inputted to the light guiding plate to the key-pad. The switch member is positioned in a lower part of the touch sensor. The key-pad assembly further includes a light source(202) and a first printed circuit board(201). A light emitting surface of the light source faces a side surface of the light guiding plate. The first printed circuit board supports the light source on the light guiding plate and is electrically connected to the touch sensor.
