Each of the electrophoretic particles has a second color different from the first one. Another display is also provided.
Abstract:
An electronic advertising method and an electronic apparatus are provided. In the method, an amount of a factor of the electronic apparatus in executing a task function is accumulated and whether the amount is over a preset value of the electronic apparatus or not is determined. An advertisement is displayed if the amount is over the preset value and a question according to content of the advertisement is displayed. An operation responding an answer to the question is detected and a non-advertisement function is executed if the operation is detected.
Abstract:
A method for manufacturing a color electrophoretic display device includes the following steps. First, a substrate having a displaying region and a circuit region around the displaying region is provided. Next, a driving array is formed in the displaying region. Subsequently, an electrophoretic display layer is formed on the driving array. Afterwards, a thermal transfer process is performed so that a color filter layer is formed on the electrophoretic display layer. The method can increase the production eligibility rate of the color electrophoretic display device, thereby improving the display quality of the color electrophoretic display device.
Abstract:
Disclosed is a vehicle detection system including the processing device, the bi-stable display connected to the processing device and the detector connected to the processing device. The detector detects the status information of the vehicle to be processed by the processing device, and then the processed status information is displayed on the bi-stable display. The processed status information can be displayed for a long time without power consumption. In addition, the upkeep/repair records and the status information further can be stored in the memory device, and the user is reminded to proceed the upkeep/repair and the to replace the vehicle's components.
Abstract:
A touch display apparatus comprises a touch display structure and a touch controller electrically connected thereto. The touch display structure comprises a display layer, an electric circuit layer, and a second electrode. The electric circuit layer, disposed under the display layer, comprises a substrate, a driving electrode, and a first electrode. The driving electrode and the first electrode are disposed on an upper surface and a lower surface of the substrate, respectively, and are electrically connected to the touch controller, respectively. The second electrode is disposed under the first electrode and electrically connects to the touch controller. The first electrode and the second electrode generate a touch control signal in response to a press of a user or an electromagnetic signal. The touch controller receives and processes the touch control signal, and then, the touch controller transmits the touch control signal to the driving electrode to drive the display layer.

Abstract:
A LED driving device comprises a rectification circuit, a holding current circuit and a driving circuit to drive and linearly regulates an illumination brightness of at least one LED by utilizing level variation of current magnitude. The rectification circuit rectifies and outputs a rectified voltage to the holding current circuit and the driving circuit by filtering impulses via a filter after receiving an alternating current voltage. The driving circuit outputs a driving current filtered by a filter capacitor to the LED, and the driving current is sensed by a sensing resistor to allow the holding current circuit outputting a holding current to the rectification circuit such that the whole circuit power can be improved to reduce problems of noise interference and twinkling.
