摘要:
A method for supporting session mobility, more particularly, a method for supporting session mobility that can move various sessions between two or more devices by using session initiation protocol (SIP). Various sessions can be simultaneously moved by utilizing a SIP PUBLISH message. Accordingly, a user can utilize various services as they are regardless of changing of service receiving device while the user utilizes various services. Also, the session mobility can be effectively supported whether the target of the session movement is known or not.

A flat panel display device is provided with an increased viewing angle having good dark versus light imaging contrast. The display device includes a display panel, a first optical unit, and a second optical unit. The display panel includes a liquid crystal layer that is driven in a vertical alignment mode. The first optical unit includes a negative C-plate and a first polarizer having a first absorption axis. The second optical unit includes a biaxial compensation plate having a refractive indices coefficient, (nx−nz)/(nx−ny) of more than 0.45 and less than 0.55, and a second polarizer having a second absorption axis crossing the first absorption axis. The biaxial compensation plate has a refractive indices relationship of nx>nz>ny such that dispersion of polarization states of colored light rays passed through the C-plate and the liquid crystal layer may be minimized and gathered about an extinction point, thereby improving contrast at side viewing angles.

A method of manufacturing a display device includes forming a buffer layer on a top surface of a substrate, forming an amorphous silicon layer on a top surface of the buffer layer, and forming a polysilicon layer by irradiating the amorphous silicon layer with a laser beam. A plurality of first protrusions are formed on the top surface of the polysilicon layer, and a plurality of second protrusions are formed on a surface of the buffer layer by transferring the shape of the polysilicon layer to the buffer layer. A gate insulator on the buffer layer is then formed in the shape of bumps of the second protrusions.
