    摘要: A backlight unit for a liquid crystal display which can achieve substantially uniform luminance over the entire display screen includes: a light-guide plate guiding incident light and having a diffusion pattern for emitting light upward, the diffusion pattern being formed on at least one of upper and lower surfaces of the light-guide plate; and a point light source assembly disposed on at least one side portion of the light-guide plate, the point light source assembly including a plurality of point-light-source elements and a support substrate, in which the point-light-source elements are disposed on the support substrate and supply the light to the light-guide plate. An edge portion of one surface of the light-guide plate, which is adjacent to the point light source assembly, includes a first region corresponding to the point-light-source elements and a second region corresponding to a position between the point-light-source elements. The diffusion pattern may be formed in such a manner that the second region has a higher density than the first region.

    摘要: A gate IC protection device that protects a gate IC from damage and allows image to be generated normally even when an abnormal vertical synchronization start signal is received is presented, along with a gate driver and a liquid crystal display employing the gate IC protection device. A method of protecting a gate IC in a display device is also presented. The gate IC protection device includes a vertical synchronization start signal converting unit and a signal delay unit. The vertical synchronization start signal converting unit receives a first vertical synchronization start signal and a level control signal, performs a predetermined logic operation thereon, and outputs a second vertical synchronization start signal. The signal delay unit receives the second vertical synchronization start signal and outputs the level control signal that is fed back to the vertical synchronization start signal converting unit in synchronization with a gate clock signal.
