摘要： A backlight assembly that improves color uniformity is presented. The backlight assembly includes a plurality of point light sources, an optical member on the point light sources, and a reflecting plate that is positioned to receive light that is reflected by the optical member. The point light sources includes a red light emitting diode generating red light, a green light emitting diode generating green light, and a blue light emitting diode generating blue light. The optical member transmits white light formed by mixing at least some of the red, green and blue lights and reflects the untransmitted portion of the red, green and blue lights. The reflecting plate, which receives the reflected light from the optical member, includes a plurality of patterns that reflect the incident red, green and blue lights, essentially “recycling” the light that did not get transmitted in the first pass.

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 A2, the lens satisfies the equation: A1+A2

摘要： A method of driving a light source, a light source apparatus for performing the method, and a display apparatus having the light source apparatus are disclosed in accordance with one or more embodiments. In the method, a plurality of light source strings connected in parallel is driven by applying a driving voltage to a first terminal of the light source strings. A peak current due to a voltage deviation of each of the light source strings is switch-controlled to uniform an average current of the light source strings. Thus, a peak current flowing through light source strings in accordance with a voltage deviation of the light source strings is switch-controlled, so that an average current of the light source strings may be uniformly maintained. Therefore, a voltage deviation is not consumed as power, so that damage to circuit elements due to heat may be prevented.
摘要翻译：根据一个或多个实施例公开了一种驱动光源的方法，用于执行该方法的光源装置和具有该光源装置的显示装置。在该方法中，通过向光源串的第一端施加驱动电压来驱动并联连接的多个光源串。由于每个光源串的电压偏差引起的峰值电流被开关控制以使光源串的平均电流均匀。因此，根据光源串的电压偏差流过光源串的峰值电流是开关控制的，使得可以均匀地保持光源串的平均电流。因此，不会将电压偏差作为功率消耗，从而可以防止由于热而对电路元件造成的损坏。

摘要： A display apparatus includes light source blocks driven as follows in displaying at least one frame (possibly every frame). An image to be displayed includes image pixels. Each light source block corresponds to an image pixels block which is a block of image pixels to be displayed directly opposite to the light source block. For each image pixels block, a block mean value and a block maximum value are determined. A parameter is determined which corresponds to a total luminance of the frame. For each image pixels block, a block representative value is determined which corresponds to the parameter, the block representative value being within a range between the block mean value and the block maximum value inclusive. During the frame, each light source block is driven to provide a luminance which is an increasing function of the corresponding block representative value.
