  • Publication number: 20180061332
    Abstract: A driving device of automatically adjusting a frame rate for an active matrix electrophoretic display and a driving method thereof are provided. The driving method has a phase signal generation step for generating a plurality of phase signals, a phase signal processing step for processing an Nth phase signal and an (N+1)th phase signal, an union step, and an output step for outputting a driving voltage selecting signal, a latch signal and a gate driver control signal. Thus, the power consumption can be reduced by analyzing to maintain or reduce the frame rate of the active matrix electrophoretic display.

  • Publication number: 20170010730
    Abstract: A touch display module having a pressure detection mechanism is provided. The touch display module includes a 3-D (three-dimensional) sensor and a 3-D controller. The 3-D sensor includes touch units and at least one pressure sensing unit. The 3-D controller includes a driver and a driving pulse processor. The driver provides a pressure scan pulse to the pressure sensing unit and a touch scan pulse to the touch units in combination with the driving pulse processor. The present disclosure further provides a driving method corresponding to the touch display module having the pressure detection mechanism including steps of: providing pressure scan pulses to the pressure sensing unit by the driver in combination with the driving pulse processor and providing touch scan pulses to the touch units in combination of the driving pulse processor by the driver.

  • Publication number: 20170010740
    Abstract: The present invention discloses a display device with a three-dimensional input module, and the device includes a pressure sensor, a display module having a position input function, and a common controller. The pressure sensor is used for detecting pressing force values of multiple points in Z direction. The display module having the position input function is disposed on one side of the pressure sensor and used for detecting press positions of multiple points in X direction and Y direction and displaying. The common controller generates pixel-scanning pulses and touch-scanning pulses for the display module having the position input function, and generates pressure-scanning pulses for the pressure sensor to detect multiple input positions and multiple pressing force values corresponding to the multiple input positions. The display device with the three-dimensional input module has advantages of simple hardware design and better noise immunity.

  • Publication number: 20160301175
    Abstract: A crimping apparatus comprising a press module connected with a pressing mold, a translation module, and a pressure control module is disclosed. The press module generates an action force on the pressing mold through a fluid. The translation module is coupled to the press module for driving the press module to move toward a flexible printed circuit having two isolated circuit layers such that one circuit layer is pressed to crimp to the other circuit layer, wherein the pressure control module adjusts the pressure within the press module to maintain a constant force on the pressing mold whereby the pressing mold can generate a constant stress acting on the flexible printed circuit during the crimping process. In addition, the crimping apparatus can be adapted in a roll-to-roll process for crimping two isolated circuit layers of each flexible printed circuit unit arranged on the roll.

  • Publication number: 20080074891
    Abstract: The present invention is to provide a light comprising a shade, one or more reflection members facing an inner surface of the shade, and one or more light-emitting members each provided at one end of each of the reflection members. The reflection members and the light-emitting members are concealed by the shade so as to protect the reflection members and the light-emitting members. Light emitted by the light-emitting members is transmitted through the shade after being deflected by the reflection members.
