  • Publication number: 20160308513
    Abstract: A data driver includes shift registers, sampling latches, holding latches, and a data sensing unit. The shift registers generate sampling pulses by shifting a source start pulse in response to a source sampling clock. Each of the sampling latches receives current data and stores the current data in response to each of the sampling pulses. Each of the holding latches receives the current data stored in each of the sampling latches, and stores the received current data in response to a source output enable signal. The data sensing unit receives the current data corresponding to an i-th sampling latch of the sampling latches or an i-th holding latch of the holding latches (i is a positive integer) and previous data stored in the i-th sampling latch or the i-th holding latch, compares the current data with the previous data, and generates control data based on the comparison result.

  • Patent number: 7999884
    Abstract: A liquid crystal display includes a liquid crystal display panel, a light source, a wire, a light guide plate, a bottom chassis, and a light source container. The liquid crystal display panel displays an image, and the light source generates a light. The wire connected to the light source, and the light guide plate guides the light from the light source to the liquid crystal display panel. The bottom chassis receives the light guide plate and the light source, and the bottom chassis is divided into two parts separable with each other. The light source container is integrally formed with the bottom chassis and surrounding at least a portion of the light source. The light source container includes a fixing section fixing the wire.
