  • Patent number: 7483007
    Abstract: An alternating electric field is applied across liquid crystal cells of pixels of an optically compensated birefringence mode liquid crystal display during a time period after power is provided to the display to cause the liquid crystal cells to change from a splay state to a bend state. The alternating electric field has a frequency that is less than 40 Hz. After the liquid crystal cells change to the bend state, a backlight module is turned on, and the pixels are controlled to show images with a refresh rate of greater than 40 Hz.

  • Publication number: 20070274262
    Abstract: A home agent (200) for registering with a serving node (400) in a home network (10) includes a packet filter module (210), an agent control module (220), and a registration module (240). The packet filter module detects a mobile registration packet transmitted from a mobile node (100) and informs the agent control module. The registration module registers with the serving node by transmitting a registration request packet when the agent control module is informed by the packet filter module. The registration request packet includes a home address field and a care-of address (CoA) field. The home address field is set to an Internet protocol (IP) address of the mobile node in the home network, and the CoA field is set to an IP address of the home agent. A registration method, a network system, and a network roaming method are also provided.

  • Publication number: 20070274255
    Abstract: A mobile node (10) roams from a home network to a foreign network, and comprises an address detection module (101) and an address conversion request module (107). The address detection module detects a current address of the mobile node. The address conversion request module transmits an address conversion request message to a home agent according to the current address of the mobile node and an address of the home agent, receives an address conversion response message from the home agent, and generates an address mapping relationship between a home address and the current address of the mobile node. A network system and a network roaming method are also provided.

  • Patent number: 7233375
    Abstract: A liquid crystal display includes a first substrate and a second substrate, a liquid crystal layer disposed between the first and second substrate, and a backlight module disposed under the second substrate. The first substrate comprises color filters disposed in array, wherein each color filter has a chromaticity-adjusting region; a thickness of the color filters and a size of the chromaticity-adjusting region are adjustable for adjusting the chromaticity of the LCD. The second substrate comprises pixel electrodes corresponding to the color filters. Therefore, the liquid crystal display can easily adjust and perfect the chromaticity of the liquid crystal display under the restrictions of the material of the color filters, the backlight module, and the design thereof.

  • Publication number: 20060248243
    Abstract: A method for storage space allocation is disclosed. According to the present invention, the video data and the still picture data are recorded in a common storage area on a re-writable disc. When the still picture data is to be stored, it is recorded from the high-address end of the common storage area. On the other hand, when the video data is to be stored, it is recorded from the low-address end of the common area.
