Title: Flat panel display and method of manufacture
Inventor: AN CHENGWU
IPC: G09F9/00
Filed: 2001-12-01
Abstract: PURPOSE: A flat panel display device and a manufacturing method thereof are provided to form the even thickness of the liquid crystal layer by distributing spacers evenly and accurately without concentration with adjusting gaps between cells. CONSTITUTION: In a flat panel display, a spacer array is created on a transparent substrate(10') to maintain two substrates(10) at the pre-determined spacing in the finished panel. Spacers(20') are distributed between the two substrates, which are sealed by using sealant(18) resulting in a cell gap with pre-determined spacing distance. The gap between the two sealed substrates forms a cell for liquid crystal(22). A laser is used to create the spacers on a surface of the glass substrate. The glass is locally molten by the converged laser beam. Under the effect of surface tension, the melted glass forms bumps which remain during cooling. The laser-induced spacers have a pre-determined profile with uniform height, diameter and distribution. The spacer characteristics are flexibly and precisely controlled.

Title: Improved method and arrangement for changing cells
IPC: H04W36/26
Filed: 1999-09-16
Abstract: The invention pertains to an improved method and arrangement for cell selection performed by a mobile station in a cellular radio system. Particularly the invention pertains to cell selection in a situation where the mobile station is connected to a special service such as the GPRS (General Packet Radio Service) offered by the current cell. An essential idea of the invention is that a base station sends to the mobile station information about whether the base station of a neighbouring cell offers the same service. This information is sent preferably in a signalling message of a certain service, such as the PSI3 message of the GPRS system (70) or in a system information SI message of a lower-level service, e.g. in a SI3 message. The mobile station changes serving base stations directly, without having to use lower-level system signalling (72) in between. The invention helps adjust cell reselection such that the load on the mobile station and radio signalling, caused by measurement of possible new cells and by message traffic, is as small as possible.
