Abstract: A backlight assembly includes a light source, a light-guide plate and an integrally formed frame. The light-guide plate guides light generated from the light source. The integrally formed frame includes a chassis and a mold frame integrally combined with the chassis as an indivisible unitary element through insert/outsert injection. The integrally formed frame receives the light source and the light-guide plate. A hemming part is formed on a sidewall of the chassis to increase strength of the integrally formed frame. Therefore, the number of elements is decreased, and strength against bending stress, impact resistance and heat dissipation are improved.

Abstract: Disclosed is an electrophoretic display and a method for driving the electrophoretic display. The method for driving the electrophoretic display, which includes a first electrode, a second electrode, and an electrophoretic layer including electrophoretic particles disposed in a plurality of pixels receiving the voltage for driving from the first electrode and the second electrode and provided between the first electrode and the second electrode includes applying a reset voltage to the pixels, applying a reset compensation voltage including reversed polarity to the reset voltage to the pixels, applying an image display voltage including the same or different polarity during a predetermined time between the neighboring pixels, and applying an image display compensation voltage including reversed polarity to the image display voltage to the pixels during a predetermined time. The foregoing method provides a potential distribution which is symmetrical in the boundary region between the neighboring pixels such that the display size of the real image of each of the pixels is uniform and an afterimage may be prevented, thereby improving the display performance.
