Abstract: An imaging device and an imaging method are provided. An incident beam is separated into a first spectroscopic beam and a second spectroscopic beam by a spectroscopic unit and the first spectroscopic beam and the second spectroscopic beam are respectively incident on a first imaging module and a second imaging module. One of a phase detection autofocus (PDAF) mode and a contrast detection autofocus (CDAF) mode of the first imaging module is activated based on a brightness of an ambient light source. The first imaging module and the second imaging module are activated to shoot at a partially overlapping field of view (FOV) to obtain a first image and a second image. The first image and the second image are superimposed to obtain a composite image.

Abstract: An electronic device includes an electrophoretic image display (EPD) panel, a switch circuit includes a relay and a metal oxide semiconductor field effect transistor (MOS-FET), and a electrophoretic display control unit in communication with the EPD panel and the MOS-FET through a data bus. The electrophoretic display control unit can receive a touch signal when a click operation is performed on the EPD panel, drive the EPD panel to update an image displayed on the EPD panel by controlling two normally open terminals of the relay to connect two common terminals of the relay, and control two normally closed terminals of the relay to connect the two common terminals of the relay after updating the image of the EPD panel. Thus, the quality of the image displayed on the EPD panel is increased as a contrast value of the image is barely changed.

Abstract: A finger-mounted touch panel actuator includes a sleeve, at least one protrusion and a vibrator configured to selectively vibrate the sleeve. The sleeve includes an inner surface and an outer surface. The at least one protrusion extends from the outer surface of the sleeve. The sleeve is wearable by a user of the touch panel and the user may selectively touch the touch panel with the at least one protrusion. The vibrator vibrates the sleeve in response to a vibrating signal.

Abstract: A bi-stable display, frame updating method and timing sequence controlling method thereof are disclosed. The frame updating method of the bi-stable display includes the steps of comparing a difference of source driver output voltages of adjacent frames of image updating period with a preset threshold, and determining parameter value of each transitional state of the adjacent frames when the difference equal or greater than the preset threshold for controlling level of source driver output voltage. Accordingly, the effects such as signal interference, reduction of image quality resulted from switching between high voltage levels directly and rapidly and excessive power consumption may be eliminated.

Abstract: A display device, a back light thereof, and a method of driving the back light are disclosed in the present invention. A field emitting back light plate is used as a back light module of a passive light-emitting display device in the present invention. Because various video signals are produced in different timing, the brightness of the light and the lightening region are controlled in accordance with the video signals in the timing. Hence, the power consumption of the back light in the display device is decreased. Besides, the contrast of the display device is increased, and the life-span of the back light is lengthened.
