Title:
液晶ディスプレイにプリント回路を接続する方法
Document Type and Number:
Japanese Patent JP4464065
Kind Code:
B2
Abstract:
The liquid crystal cell comprises an upper glass (1) and a lower glass (3) confining the liquid crystal material. A connection zone (6,8) is created by positioning an extension of the upper glass on contacts facing the printed circuit board. A laser beam is used to complete the formation of a connection. The procedure provides connection between a printed circuit board and the electrode tracks of a liquid crystal display cell (10). The cell comprises an upper glass (1) and a lower glass (3), and a sealing ring (5) which serves to confine the liquid crystal material. The display cell is constructed with at least one extension (7,9) for the upper glass (1) so that its lower surface may support the electrode tracks. A connection zone (6,8) is created by positioning the extension on the contacts facing the printed circuit board. A laser beam is focussed on to the contact zone, through the upper glass, or with grazing incidence with respect to the upper glass. This establishes a permanent connection.
