  • Patent number: 11984419
    Abstract: Package structures and methods for manufacturing the same are provided. The package structure includes a first bump structure formed over a first substrate. The first bump structure includes a first pillar layer formed over the first substrate and a first barrier layer formed over the first pillar layer. In addition, the first barrier layer has a first protruding portion laterally extending outside a first edge of the first pillar layer. The package structure further includes a second bump structure bonded to the first bump structure through a solder joint. In addition, the second bump structure includes a second pillar layer formed over a second substrate and a second barrier layer formed over the second pillar layer. The first protruding portion of the first barrier layer is spaced apart from the solder joint.

  • Patent number: 9213663
    Abstract: An output input (I/O) control apparatus and a control method thereof are provided. The I/O control apparatus includes an interface control unit, a read-only memory, a random access memory, a multiplexer and a micro-process unit. The interface control unit is coupled to a memory apparatus through a bus, and the memory apparatus is external to the I/O control apparatus. The read-only memory stores judgment codes. The multiplexer is controlled by the micro-process unit to switch to the interface control unit, the read-only memory or the random access memory. When the bus is not busy, the micro-process unit can read data from the memory apparatus. When the bus is occupied and busy, the micro-process unit can read and execute codes from the read-only memory or the random access memory so as to avoid computer system instability or thermal damage.

  • Patent number: 8451285
    Abstract: A method for improving motion blur and contour shadow of a display displaying images having a number of frames includes transforming a second average gray scale into a third average gray scale when a first average gray scale for displaying a first frame is unequal to the second average gray scale for displaying a second frame. A luminance corresponding to the second frame is generated according to the third average gray scale and at least one luminance query table. The third average gray scale is greater than the first average gray scale and the second average gray scale or less than the first average gray scale and the second average gray scale.
