Abstract
The invention relates to an active matrix with data driver circuit and selection driver circuit, where the active matrix is electrically connected with the driver circuits and where it comprises electrowetting cells (EW cells) arranged in rows and columns. An EW cell comprises at least two electrodes, which are connected through at least one transistor with data lines and row lines of the driver circuits. The electrodes which are provided for controlling the EW cell are connected with the same data line and with two different control lines, where the selection driver circuit simultaneously activates the transistors which are connected with the individual selection lines by control signals and where it connects the electrodes of the respective EW cell locally so to achieve a medium voltage value.
Claims14
Display device with an active matrix, at least one data driver circuit, and at least one selection driver circuit, where the active matrix is electrically connected with both the data driver circuit and the selection driver circuit, and where it comprises electrowetting cells (EW cells) which are regularly arranged in rows and columns, where each EW cell has at least two control electrodes which are connected through at least one transistor each with data lines and selection lines of the driver circuits for addressing the EW cells, wherein
- the at least two control electrodes which are provided for controlling the individual EW cell are connected with the same data line and with two different selection lines, and in that the selection driver circuit is configured such to simultaneously activate the transistors which are connected with the individual selection lines by control signals and to connect the at least two control electrodes of the respective EW cell locally.
