Patent ID: 8094173

Claim:
A computing system for adjusting a screen resolution of a liquid crystal display module (LCM) of a portable electronic device, the portable electronic device comprising a touch panel, and a bay configured to receive and hold a stylus, the system comprising: an input module configured for receiving input signals received from the touch panel, wherein the input signals correspond to user inputs contacting the touch panel to activate one or more functions of the portable electronic device; a detection module configured for detecting usage statuses of the user inputs and for generating a status notification indicative of the usage statuses of the user inputs, wherein the status notification indicates that the user input is by finger touch if the stylus is not received in the bay and the status notification indicates that the user input is by the stylus if the stylus is received in the bay; an adjustment module configured for receiving the status notification from the detection module, and detecting a resolution mode of the LCM to determine whether the resolution mode of the LCM is compatible with the user inputs, wherein the resolution mode comprises a high resolution mode and a low resolution mode; and the adjustment module further configured for reducing the screen resolution of the LCM upon the condition that the LCM is in the high resolution mode and the user input is by the finger touch, so that user interfaces of the portable electronic device are displayed using large icons, or increasing the screen resolution of the LCM upon the condition that the LCM is in the low resolution mode and the user input is by the stylus, so that the user interfaces are displayed using small icons.
