摘要： This application is directed to driving methods for electrophoretic displays. The driving methods and waveforms have the advantage that they provide a clean and smooth transition from one image to another image, without flashing or other undesired visual interruptions. The methods also provide faster image transitions. In an embodiment, a method drives a display device from a first image to a second image wherein images of a first color are displayed with a background of a second color, which method comprises driving pixels of the first color directly to the second color before driving pixels of the second color directly to the first color.

摘要： A frequency conversion correction circuit for an electrophoretic display (EPD) which has a control circuit to capture pixel signals of a next picture and gets a corresponding update signal from a look up table to be output, and a driving circuit to provide a plurality set of potential difference signals corresponding to a plurality set of electrodes of an EPD panel according to the update signal. The EPD further has an environment detection device and a duty frequency judgment unit. The environment detection device detects the operation environments of the EPD and gets an environment parameter. The duty frequency judgment unit compares the preset signal value sections where the environment parameter is located and generates a duty frequency signal and sends to the driving circuit. The driving circuit changes and outputs the frequency of the potential difference signals in a fixed frame time according to the duty frequency signal.

摘要： The present invention is directed to reflective display devices with a luminance enhancement structure on its viewing side and at least an auxiliary layer and/or edge sealing. The structure increases the overall reflectance by reducing the total internal reflection, and as a result, the brightness of a display device is increased.

摘要： The present invention is directed to driving waveforms and a driving method for an electrophoretic display. The method and waveforms have the advantage that the changes in the driving voltages due to the shift are minimized. In addition, the overall driving time for the waveforms is also shortened due to the shortened driving frames. There are no additional data points required as the number of the driving frames remains the same. Therefore, the power consumption is nearly identical with the waveform having driving frames of a fixed frame time.

摘要： A multiplex electrophoretic display driver circuit comprises a memory unit, a display controller and a voltage driving unit. The memory unit has two registers respectively storing the current and former gray-level matrix signals. The gray-level matrix signal contains gray-level data corresponding to electrophoretic pixels. The display controller has an encoding circuit and a counting circuit. The encoding circuit generates a difference-value matrix signal containing difference values according to a difference between the current and former gray-level matrix signals and then generates a voltage-difference matrix signal containing voltage-difference signals corresponding to the electrophoretic pixels. The counting circuit receives the difference-value matrix signal and counts to generate refreshing values corresponding to the difference values. The encoding circuit adds the refreshing values to a next-cycled difference-value matrix signal to generate a new voltage-difference matrix signal. The voltage driving unit drives the electrophoretic pixels according to the voltage-difference matrix signal.
