Title: Alternating drive system for liquid crystal display device
Inventor: MANO HIROYUKI
IPC: G09G3/36
Filed: 1994-03-22
Abstract: PURPOSE:To dissolve display unevenness and to attain a display with excellent display quality by performing polarity inversion at plural lines period and constituting so that AC points performing the polarity inversion exist uniformly in an even line and an odd line. CONSTITUTION:A latch circuit 17 generates a second AC signal ML moving the AC point of a first AC signal M by one line by a line clock CL1. A frequency divider circuit 16 frequency-divides a frame signal FLM when the least significant bit of an inversion line number setting value is zero (even setting value), and generates an odd/even frame switching signal FLM1. According to the FLM1, a selector 18 switches over the M and the ML at every frame to output the AC signal Ml. By such a constitution, though the AC points concentrate to the even line or the odd line in one frame, the AC points appear uniformly in the even line and the odd line when viewing in several frames, and the display unevenness occurring due to the relation between display data change in a display pattern and an AC phase is dissolved.

IPC: H04B7/15
Filed: 1989-03-02
Abstract: PURPOSE:To attain system generation while continuing the operation to a port whose operating specification is not revised by stopping only the operation of the port when the operating specification of the port of a satellite access controller during operation is revised. CONSTITUTION:A satellite access controller 2 receiving a system generation request from a satellite network controller 1 stops the operation of only a port to be revised and sends a stop port notice to small sized earth stations 5-1 to 5-N through a satellite 4. The small sized earth stations 5-1 to 5-N receiving the notice use a port to be revised in terminal equipments 6-1 to 6-N to interrupt only a path connecting to host computers 3-1 to 3-M. Then the satellite access controller 2 executes system generation to revise the operating specification to the stopped port. Thus, while the communication operation through the satellite between the host computer and the terminal equipment continues while using a port not revising the operating specification, the system generation is applied.
