  • Publication number: 20210398938
    Abstract: A uniform pressure gang bonding device and fabrication method are presented using an expandable upper chamber with an elastic surface. Typically, the elastic surface is an elastomer material having a Young's modulus in a range of 40 to 1000 kilo-Pascal (kPA). After depositing a plurality of components overlying a substrate top surface, the substrate is positioned over the lower plate, with the top surface underlying and adjacent (in close proximity) to the elastic surface. The method creates a positive upper chamber medium pressure differential in the expandable upper chamber, causing the elastic surface to deform. For example, the positive upper chamber medium pressure differential may be in the range of 0.05 atmospheres (atm) and 10 atm. Typically, the elastic surface deforms between 0.5 millimeters (mm) and 20 mm, in response to the positive upper chamber medium pressure differential.

  • Patent number: 11145266
    Abstract: A method and a circuit for viewing-angle image compensation applied to a flat panel display are provided. A viewing-angle image compensation scheme is applied to an input image for improving a problem of color shift caused by a large viewing angle. The method further solves the blur effect in high frequency regions and color bleeding in low saturation regions of the input image after viewing-angle image compensation. In the method, a frequency distribution of the input image is detected and decremental frequency weights are assigned to the regions having high to low frequencies. A saturation distribution of the input image is detected and incremental saturation weights are assigned to the regions having high to low saturations. The weights assigned to the regions are used to designate degrees of the viewing-angle image compensation. The method can effectively reduce the effect of the viewing-angle image compensation on the image.
