An OLED display device includes a first substrate; organic light-emitting diodes each including a first electrode, an organic light-emitting layer and a second electrode on the first substrate; a passivation layer on the organic light-emitting diodes; a second substrate spaced apart from the first substrate; a color filter layer on an inner surface of the second substrate; and a color changing layer contacting the passivation layer and the color filter layer.

Organic light-emitting diode display device and method of fabricating the same

An LCD device and a method for manufacturing the same is disclosed, in which it is possible to correct a problem of insufficient or excessive supply of liquid crystal in an LCD device by controlling an amount of liquid crystal. The method includes preparing a liquid crystal cell comprised of a first substrate, a second substrate, a liquid crystal layer between the first and second substrates, and a first sealant formed in the periphery of the liquid crystal layer between the first and second substrates; measuring an amount of liquid crystal provided to the inside of liquid crystal cell; forming an inlet for liquid crystal in the first sealant; and regulating the amount of liquid crystal by supplying or discharging the liquid crystal through the inlet; and sealing the inlet.

Methods of manufacturing liquid crystal display devices

An apparatus for testing a liquid crystal display (LCD) panel which is capable of easily attaching or detaching a large polarizer to/from a test board when testing a large LCD panel, the apparatus comprising a test board for outputting light to an LCD panel which is placed thereon, a polarizer fixing unit rotatably formed at the test board and having a groove in which a polarizer is inserted, and a stop formed at the test board to fix the polarizer fixing unit to a desired position.

Apparatus for testing liquid crystal display panel

A digital cordless telephone system comprises a multiplicity of subscriber cordless handsets (HS's) with a subscriber number of a private automatic branch exchange (PABX) being assigned to one or more of the HS's, a plurality of base stations (BS's), each of the BS's being coupled with one or more of the HS's by radio channels for controlling a radio link between each of the BS's and each of the HS's, and a system connecting unit coupled with the BS's and the PABX for allowing only authenticated HS's to initiate outgoing calls and for keeping track of each of the HS's to set up calls for the HS's whenever the HS's are within the service area of one of the BS's.

Digital cordless telephone system for a private automatic branch exchange

A digital cordless telephone (CT-2) system, having a multiple number of subscriber cordless handsets (HS's) and a subscriber manager which performs authentication for the HS's, comprises a plurality of base stations (BS's), each of the BS's being coupled with one or more HS's by radio channels for controlling radio link; and a system connector coupled with each of the BS's, coupled with a public switched telephone network (PSTN) for switching and concentrating channels between each of the BS's and the PSTN, and coupled with a public switched data network (PSDN) for communicating with the subscriber manager.
