DEVICE FOR MEASURING THE TRANSMITTANCE OF A TSP(TOUCH SCREEN PANEL) CAPABLE OF CONFIRMING IR PRINTING PATTERNS FORMED ON A TSP ON THE FRONT SIDE OF A PROXIMITY LIGHTING SENSOR

摘要

PURPOSE: A device for measuring the transmittance of a TSP(Touch Screen Panel) is provided to downwardly irradiate lights through an optical cable of a light emitting unit when the light emitting unit and a light receiving unit are positioned vertically around a spaced space, thereby confirming the IR printing patterns rapidly and accurately.;CONSTITUTION: A device for measuring the transmittance of a TSP comprises a control board and a body including a control panel and a lamp. A touch panel in which the IR printing patterns are formed is on the upper part of the body. A transferring unit is formed so that the touch panel is closely adhered on one side of a holder. An irradiating stand(30) forming a space separated from the holder by being fixed on a fixing stand is installed on the holder. A light receiving unit, which confirms lights penetrated through transparent or semi-transparent IR printing patterns for each touch panel, is formed on the lower part of the holder. An optical cable(37) connected to a body by the fixing unit is installed at a position corresponding to the light receiving unit. A light emitting unit irradiates lights straightly to the IR printing patterns of the each touch panel through the optical cable.;COPYRIGHT KIPO 2013
