Abstract: An electrowetting on dielectric (EWOD) device for self-detection of an open-circuit or closed-circuit condition includes a detection chip, a power input module, a switch module, a detection module, and a determination module. The detection chip includes a channel, several driving electrodes, and a detection electrode. Each driving electrode can couple with the detection electrode to form the driving loop. The switch unit selects one of the driving electrodes to be electrically connected to the power input module for receiving a power voltage from the power input module. The detection module receives a detection voltage outputted by the detection electrode and accumulates the detection voltage to obtain an accumulated voltage. The determination module compares the accumulated voltage with a specified voltage for determining whether the driving loop is open-circuit or closed-circuit. A method for a self-detection circuit in EWOD device is also disclosed.

Abstract: A circuit applied to a television is provided. The television includes a memory and a display panel. The circuit includes an image processing circuit, a control circuit, an image capturing circuit and an output circuit. The image processing circuit processes image data to generate processed image data. The control circuit generates a control signal according to a switch signal. According to the control signal, the image capturing circuit captures the processed image data as predetermined image data and stores the predetermined image data to the memory. The output circuit transmits the predetermined image data to the display panel according to the control signal.
