  • Patent number: 7746093
    Abstract: A driving chip package, a display device including the same, and a method of testing the driving chip package are disclosed. Any contact failure between the driving chip package and the display substrate can be easily detected, thus reducing the quality management cost and preventing additional failures and increasing the manufacturing yield. The driving chip package includes a base film made of an insulating material, a plurality of interconnection lines formed (e.g., patterned) on the base film (that conduct externally processed driving signals to driving chip and that conduct the driving signals processed in and output by the driving chip), and at least one test interconnection line (e.g., a test signal input interconnection line or a test signal output interconnection line) formed parallel to the interconnection lines on the base film. A test signal input interconnection line and a corresponding test signal output interconnection line are electrically connected through a link on the display substrate.

  • Publication number: 20090051643
    Abstract: In a backlight assembly, a display apparatus having the backlight assembly, a method for driving the backlight assembly and a method for driving the display apparatus, the backlight assembly includes a plurality of light sources and a light source driving unit. The light sources are disposed along a direction and emit light. The light source driving unit causes the light sources to sequentially emit light along the direction, and causes each of the light sources to emit light during a first emitting period of a time period, and then causes each of the light sources to emit light during a second emitting period of the time period. The time period is substantially the same as a single frame. Accordingly, each of the light sources emits light again after the light sources have emitted light once, so that motion blur in the display apparatus may be decreased.
