    摘要： A liquid crystal display (LCD) apparatus time-divides a frame into a plurality of fields, in which lights having a color different from each other, are generated. The LCD apparatus includes a backlight unit. The backlight unit includes n of light-generating units sequentially generating the lights in the fields. An initial light-generating time of an nth light-generating unit being delayed by a predetermined time gap relative to the (n−1)th light-generating unit so that each of the fields includes a first period, in which one of the lights is generated, and a second period, in which at least two of the lights are generated. The light-generating units generate a peak light having a peak intensity in the first period. Thus, the intensity of light or the time period for which the light is generated, is controlled so that color mixing is minimized and color purity is improved.

    摘要： A lens for a light emitting diode is formed with a material having a refractive index of n, and the lens includes a base, a first curved circumferential surface extending from the base, a curved center-edge surface extending from the first curved circumferential surface, and a curved centermost surface extending from the curved center-edge surface. The base includes a groove for receiving a light emitting chip therein. In the lens, a distance from a center of the base to a point of the curved center-edge surface is always shorter than the radius of curvature for the point of the curved center-edge surface. The curved centermost surface has a concave shape with respect to the base. In addition, when an obtuse angle formed between a main axis of the lens and a tangent line of a point of the curved centermost surface is A1, and an acute angle formed between a straight line linking the center of the base to the point of the curved centermost surface and the main axis of the lens is A 2, the lens satisfies the equation: A1+A2

    摘要： A power supply includes a light source, a signal converting unit converting an externally supplied AC voltage into a DC voltage, a DC-DC converting unit converting a magnitude of the DC voltage, and a light source protecting unit. The light source protecting unit outputs the DC voltage of a predetermined range as a light source driving voltage to supply a stabilized source driving voltage to the light source and suspending an application of the light source driving voltage to the light source when a magnitude of the light source driving voltage is larger than a predetermined value, based on an externally supplied control signal.
