Abstract:
A device and a method for upgrading firmware are provided to reduce memory usage in a mobile terminal by compressing and decompressing data stored to a memory with a virtual driver, which supports firmware upgrade using a FOTA(Firmware Over-The-Air) technology. An interface module(610) communicates with other nodes. A virtual driver manager(640) compresses information when a request for writing information received through the interface module to a memory is received from an upper layer, and distributes/stores the compressed information to first and second area when the compressed information is bigger than a size set in the first area. The virtual driver manager calculates a position of the information, loads/decompresses the information stored in the calculated position, and transfers the decompressed information to the upper level when a read request for the information is received. The first area is a compressed software image of binary information storage area, and the second area is a reserved area. A controller performs basic process or control over a mobile terminal, and a storage stores software for the control and temporary data which are generated during the execution of the software.
Abstract:
An LCD(Liquid Crystal Display) is provided to rapidly display a desired image by immediately initializing a driving part in case a certain display region displays a reversed image due to static electricity. An LCD comprises a TFT display plate, a common electrode display plate, a first driving chip(410), a second driving chip(412), a phase detection part(434), and a reset part(436). The TFT display plate has a display area containing the first display region and the second display region and a peripheral area formed around the display area. The common electrode display plate, where common electrodes are formed, is arranged opposite to the TFT display plate so as to have the same area as the display area. The first driving chip, installed at the peripheral area, creates the first common voltage mother signal to supply common voltage to the common electrodes formed at the first display region. The second driving chip, installed at the peripheral area, creates the second common voltage mother signal to supply common voltage to the common electrodes formed at the second display region. The phase detection part detects whether the phase of the first common voltage mother signal is identical to the phase of the second common voltage mother signal. If the phase of the first common voltage mother signal is different from the phase of the second common voltage mother signal, the reset part initializes the first driving chip and the second driving chip.
Abstract:
A method and an apparatus for downloading software in a mobile terminal is provided to prevent important information from leaking out due to illegal hacking by preventing a binary, of which the version is lower than an existing binary of a mobile terminal, from being downloaded using version information and hash information. A mobile terminal, if the authentication information of a new binary is received from a downloader, decodes the authentication information using an RSA public key(301,303). If the authentication information is decoded normally, the mobile terminal confirms the version of the authentication information, searches for an existing binary of the same type as the new binary, and compares the confirmed version with the version of the searched binary(307,309). In case the version of the authentication information is lower than the version of the existing binary, the mobile terminal transmits a downgrade impossible message to the downloader(323). However, if the version of the authentication information is higher than or equal to the version of the existing binary, the mobile terminal transmits a download accept message to the downloader(311). Then the mobile terminal checks whether the new binary is received from the downloader(313). If the new binary is received, the mobile terminal confirms whether the hash information of the received binary is matched with the hash information of the authentication information(315,317).

A backlight unit and an LCD(Liquid Crystal Display) having the same are provided to suppress the loss of light in an air layer positioned between a light guiding plate and a reflecting layer, by coating a rear surface of the light guiding plate with a reflective material having higher refractive index than the light guiding plate so as to totally reflect the light advancing in a direction of the rear surface of the light guiding plate. A lamp(134) generates light. A light guiding plate(112) guides the light generated from the lamp. A coating layer(120) is formed on a rear surface of the light guiding plate to reflect the light advancing in a direction of the rear surface of the light guiding plate. The coating layer has a higher refractive index than the light guiding plate. The coating layer is formed of aluminum or silver. An anti-oxidizing layer is formed on a surface of the coating layer to prevent the oxidation of the coating layer.
