Abstract: A method includes forming an interposer, which includes forming a rigid dielectric layer, and removing portions of the rigid dielectric layer. The method further includes bonding a package component to an interconnect structure, and bonding the interposer to the interconnect structure. A spacer in the interposer has a bottom surface contacting a top surface of the package component, and the spacer includes a feature selected from the group consisting of a metal feature, the rigid dielectric layer, and combinations thereof. A die-saw is performed on the interconnect structure.

Abstract: A method for forming a chip package structure is provided. The method includes disposing a chip over a redistribution structure. The method includes forming a molding layer over the redistribution structure and adjacent to the chip. The method includes partially removing the molding layer to form a trench in the molding layer, and the trench is spaced apart from the chip.

Abstract: An apparatus for driving a display panel includes an output terminal for outputting driving voltages to the display panel, a source driver for intermittently outputting data voltages to the driving voltage output terminal and at least one charge sharing branch connected to the driving voltage output terminal. Each of the at least one charge sharing branch includes a charge sharing capacitor and a charge sharing switch connected in series between the driving voltage output terminal and ground, enabling the accumulation and supply to the display of the necessary reverse driving voltages, from a single intermittent source driver instead of from two independently-powered opposite polarity sources.

Abstract: An electronic device includes a first display for displaying static images, and a second display for displaying dynamic images. The first display includes a plurality of first pixels, and the second display includes a plurality of white pixels. The first display is stacked on the second display, and the plurality of first pixels respectively correspond to the plurality of white pixels.

Abstract: A source driver includes a shift register, a latch, a digital to analog converter (DAC), an output buffer, a level shifter, and a comparator. The shift register receives digital image data. The latch stores digital image data under control of the shift register. The DAC is coupled to the latch and converts digital image data to analog image data. The level shifter shifts a voltage level of analog image data, generates a number of first driving voltages, and outputs the first driving voltages to the output buffer. The comparator controls a voltage generator to generate a number of second driving voltages between corresponding two neighboring first driving voltages; and the voltage generator outputs the second driving voltages to the output buffer. The output buffer sequentially outputs the first driving voltages and the second driving voltages.
