Abstract: A package comprises a substrate including a first surface, and an upper conductive layer arranged on the first surface, a first light-emitting unit arranged on the upper conductive layer, and comprises a first semiconductor layer, a first substrate, a first light-emitting surface and a first side wall, a second light-emitting unit, which is arranged on the upper conductive layer, and comprises a second light-emitting surface and a second side wall, a light-transmitting layer arranged on the first surface and covers the upper conductive layer, the first light-emitting unit, and the second light-emitting unit, a light-absorbing layer, which is arranged between the substrate and the light-transmitting layer in a continuous configuration of separating the first light-emitting unit and the second light-emitting unit from each other, and a reflective wall arranged on the first side wall, wherein a height of the reflective wall is lower than that of the light-absorbing layer.

Abstract: Techniques for color change of Information elements (IEs) are described. In an example, a color of the IE and a color of a region of a virtual environment surrounding the IE may be compared. Based on the comparison, it may be determined whether the IE is distinguishable from the region of the virtual environment. Further, based on the determination, the color of the IE may be changed to facilitate distinguishability of the IE.

Abstract: A terminal computer display assembly, which fixes a monitor onto a rotary supporting base provided. The support has a set of rails with a plurality of positioning units longitudinally aligned, and an inclined angular-positioning unit to limit the backward inclination of the support within a particular range of angles. The monitor is fixed onto a sliding block which is attached to the set of rails, allowing the monitor to move up or down freely for in a suitable highly location. A buffering unit is installed between the sliding block and the base, and it can prevent the monitor from falling instantaneously while positioning the height. The base is furthermore built with a circuit board inside for act as in interface for connecting to other accessories.

Abstract: The mean for the universal serial bus hide and swing, its body inside have a sliding unit its head pivot to establish on can swing from as of deal with USB, and a memory to equip the electricity conjunction in deal with USB. The USB can conceal in the body, or along with the sliding unit to swing after being moved the indentation of the body.
