Package of a controller and screen control module with the same

Abstract

A screen control module of a mobile electronic device has at least one controller formed on a circuit board. The circuit board has multiple solder pads formed on the circuit board and respectively aligning along a first direction and a second direction. An amount of the solder pads along the first direction is greater than that along the second direction. The controller is formed by an integrated circuit with a package, and the aspect ratio of the package is not less than 2. The package has multiple electrical contacts respectively aligning along a length direction and a width direction. Each electrical contact aligns with and is electrically connected to a corresponding solder pad. Accordingly, the screen control module mounted within a side frame of a display of the mobile electronic device can increase the aspect ratio to meet the demand for narrowing the side frame of the display.
