Embodiment Construction

[0034] Depending on the different shapes and materials of the electrowetting display, the values ​​of digital voltage, non-selected voltage and selected voltage can be set accordingly, and the values ​​of on-voltage and off-voltage are the result of cell design / layer structure. In order to better illustrate the implementation process of the present invention, the on-voltage of the pixel of the electrowetting display is 15V, and the off-voltage of the pixel of the electrowetting display is 9V. According to different shapes and materials of the electrowetting display, any other voltage value capable of turning on / off the electrowetting display can also be set. The voltage of a certain row of the electrowetting display is applied to the common electrode, and the voltage of a certain column of the electrowetting display is applied to the digital electrode. The actual voltage at a certain pixel of the electrowetting display is jointly affected by the voltages respectively applied t...

Abstract

The present invention provides a bistable driving method for an electrowetting display, comprising: setting an unselected voltage for one or more writing lines, the unselected voltage being less than the turn-on voltage minus the digital voltage and greater than the turn-off voltage; The row voltage of one or more write rows is switched from an unselected voltage to a selected voltage that is less than the turn-on voltage and greater than the turn-on voltage minus the digital voltage; applying said digital voltage such that the voltage of at least one pixel determined by said one or more write rows and at least one column to be written is greater than the turn-on voltage; changing the row voltage of one or more write rows from a selected voltage Switching to a non-selected voltage and reducing the digital voltage applied to the at least one column to 0V; applying the steps described above to the next one or more writing rows until the display is written to full screen. This driving method is fast and stable, and can reduce the number of electrodes used.

Description

technical field [0001] The invention relates to a driving method and an electrowetting display, in particular to a bistable driving method of the electrowetting display and a related electrowetting display, and belongs to the field of electrowetting display. Background technique [0002] Electrowetting displays are becoming more attractive due to their combination of high brightness, high contrast ratio, large viewing angle and fast switching speed. These properties make electrowetting displays suitable for video applications. In theory, electrowetting displays can be made transmissive or reflective. For reflective electrowetting displays, energy consumption can be relatively low since no backlight is required. [0003] Electrowetting displays generally include: a hermetically sealed electrowetting cell, polar and non-polar liquids (such as water and oil) with different optical properties contained in the cell, several electrodes (such as digital electrodes and common ele...
