An image display device is provided. The device includes a display screen, a storage unit, and a processing unit. The storage unit stores images and selection interface information. The selection interface information includes a plurality of catalogues each of which collects one or more images. The processing unit includes a selection interface display module, a selection control module, and an image search module. The selection interface display module controls the display screen to display a selection interface that provides the catalogues for selection according to the selection interface information. The selection control module generates a selection signal in response to a selection operation on the selection interface. The selection signal indicates which catalogue on the selection interface is selected. The image search module searches the storage unit for the images according to the selection signal. An image display method is also provided.

An exemplary electronic device capable of automatically selecting a power source includes two power ports configured to connect to external power sources and a battery compartment configured to receive a battery module. The voltage of the battery module is higher than at least one of the external power sources. The electronic device further includes a power selection module allocated between the battery module and the power port which selects the lower voltage. Three diodes are respectively located on the output path of the three power sources. A path switch that controls whether power to the device comes from the battery compartment or a power port is located between the anode of the battery compartment and the diode located on the output path of the battery module. Among the multiple power sources, the external power source providing a higher voltage is the first to be chosen to power the electronic device.

A touch sensing apparatus is provided. The apparatus includes a sensor (13), a flip-flop (16), and a microcontroller unit (17). The sensor is connected to one of input of the flip-flop for receiving electricity signals from an object that touches the sensor. The MCU respectively supplies two AC signals at two outputs thereof to two inputs of the flip-flop. The flip-flop outputs a first type output signal at the output thereof when the sensor not being touched. When being touched, the sensor receives electricity signals from an object, and causes a delay of an AC signal to be inputted to the input of the flip-flop to which the sensor is connected, the delay of the AC signal to be inputted to the input of the flip-flop further causes the flip-flop to output a second type output signal at a output thereof. The MCU detects a change of the output signals of the flip-flop from the first type output signal to the second type output signal and accordingly identifies a touch on the sensor.

A touch sensing apparatus is provided. A preferred embodiment of a touch sensing apparatus includes a sensor (13), an MCU (15), and an integration circuit (14). The sensor is for receiving electricity signals from an object that touches the sensor. The MCU (Microcontrol Unit) has a signal output port A and a signal input port B. The signal input port is connected to the sensor. The integration circuit interposes between the signal output port and the signal input port of the MCU. The signal output port outputs AC signals to the signal input port through the integration circuit. The integration circuit prolongs active transition times of the AC signals, and the MCU identifies a touch on the sensor when the active transition times of the AC signals fall in a predetermined range and accordingly implements a predetermined function.
