摘要： A light-generating device includes a driving substrate and a plurality of light source arrays. The driving substrate has a rectangular planar shape. The plurality of light source arrays is formed on the driving substrate. The light source arrays include at least one light emitting diode to generate light in response to power being applied through the substrate, and the light source arrays are spaced apart from each other. Thus, heat generated from the light-generating device is rapidly dissipated from the light-generating device, improving brightness of the light, brightness uniformity of the light and color reproducibility of the light.

摘要： In an anisotropic conductive film including conductive particles, and a bump, and a packaging structure of a semiconductor chip having the anisotropic conductive film and the bump, the anisotropic conductive film includes a resin layer and the conductive particles. The anisotropic conductive film electrically connects an electrode of a substrate and the bump of a semiconductor chip. A volume ratio of the conductive particles to the resin layer is about 0.1 to about 0.12. A number of the conductive particles per cubic millimeter (mm3) is about 4 millions to about 7 millions. A standard deviation of heights of the bumps is no more than about 0.25. An interval between each of the bumps and an electrode of the substrate is no more than about 1.3 μm. Therefore, the size of each of the conductive particles is optimized so that a failure probability of the open circuit is decreased.

摘要： In a drive IC and a display device having the same, the drive IC includes a plurality of bumps disposed on a lower surface of the drive IC and aligned in a plurality of rows along an edge of the drive IC. The bumps aligned in different rows from each other are juxtaposed in a direction perpendicular to a direction in which the bumps are aligned. Accordingly, when the drive IC is mounted on a display panel using an anisotropic conductive film, the anisotropic conductive film may be smoothly flowed through a space defined by the bumps of the drive IC, thereby improving electric properties of the drive IC and display device.

摘要： A light generating device includes a circuit board and a plurality of light source units. Each of the light source units includes a first light source group and a second light source group. The first light source group includes at least two light sources spaced apart from each other by a first distance and the second light source group including at least two light sources. Each of the light sources of the second light source group is spaced apart from a first virtual line segment connecting centers of the light sources of the first light source group by a second distance that is larger than the first distance. A second virtual line segment connecting centers of the light sources of the second light source group crosses the first virtual line segment.
