A cold-cathode tube has hitherto been used as a backlight for supplying illumination to a liquid crystal television but recently, light emitting diode pieces have been used for a backlight of a large-size liquid crystal television. For the purpose of improving the emission efficiency, flip chip mounting of the light emitting diode piece is advantageous but the mounting yield is restricted by the piece size, electrode structure and wire pattern structure, facing situations having difficulties in realizing simplified mounting and reduction of costs of members. In a liquid crystal display apparatus having a liquid crystal panel, an optical system and a light source, the light source includes a light emitting element structure having positive and negative electrodes, at least one of them being plural, and wires mounted to the positive and negative electrodes through flip chip mounting by making electrical correspondence to individual regions of the positive and negative electrodes.

The invention is related to method for upgrading software in wireless communication system in order to guarantee that RRU can be upgraded reliably, stably, and rapidly. The invention includes steps: (1) radio frequency unit (RFU) at remote end loads software of optical interface module (OIM) in current version, and reports the version of software to up level; (2) baseband pool unit determines whether software of OIM is needed to upgrade; if yes, then RFU at remote end down loads software of OIM in new version from the baseband pool unit, and saves it to built in memory and loads and runs it; if not, then ending step; (3) RFU at remote end detects whether communication link on the optical interface is normal; if yes, then upgrading operation is successful; if not, then RFU at remote end resets and loads software of OIM in old version. The invention reduces increment of network flux caused by that multiple RRUs obtain software of OIM from BBU at same time.

The invention discloses a start-up method of a CPU system and a system thereof. The start-up method comprises powering on a single board, starting a BOOT FLASH chip and running version software therein to boot the start-up of the CPU system, if the starting or running is failed, resetting the single board and starting another BOOT FLASH chip and running version software therein to boot the start up of the CPU system. The invention protects key points during the start-up process of the CPU system by adopting coordination of software and hardware through the two BOOT FLASH chips, when the start-up of the BOOT FLASH or the version software running is failed, the CPU start-up can be booted by restarting another BOOT FLASH, and the software of the two BOOT FLASH chips can be updated, so as to realize more reliable CPU system start-up and updating of the boot program.

The present invention discloses a display device which is configured with a liquid crystal display panel and a backlight module. The backlight module includes at least an optical film and a mainframe structure which includes a plastic frame and a backboard integrally with the plastic frame. The backboard includes an integral bottom to support the optical films of the backlight module, and a first sidewall. Wherein the plastic frame is integrally formed with a carrying portion. a second sidewall, and a supporting portion, wherein the carrying portion is used to position optical films, and also support the liquid crystal display panel, wherein to receiving slot is defined, between the second sidewall and the supporting main portion such that the first sidewall is received therein, wherein the supporting portion includes an integrally formed main portion interconnected to the carrying portion and a positioning block which prevent the plastic frame from transversal movement with respect to the backboard together with the bottom of the backboard. The present invention readily increases the stability and firmness of the plastic frame.

The invention discloses method and system for upgrading processes. The method includes steps: creating target process, and backing up the process data of the source process to the target process; when receiving integrated data form socket interface, the method stops interacting data with the socket interface, and backing up the receiving data to the target process; after finishing backing up operation, the target process sends switch request to the socket interface; after receiving information of the switch request, the socket interface switches socket service to the target process in order to carry out data interaction between the target process (through the socket interface) and the opposite terminal connected to the socket interface. Under precondition without disconnecting the socket, the invention carries out reliable and smooth upgrading.
