Abstract:
1. A display device, comprising: a substrate; a first driving electrode layer on the substrate; a first display material layer on the first electrode layer; a common electrode layer on the first display material layer; a second display material layer on the common electrode layer; a second driving electrode layer on the second display material layer; and a controller coupled to said first and second driving electrode layers and the common electrode layer for concurrently driving the first and second display material layers by: based on image signals inputted for the first and second display material layers, generating first and second writing waveforms for the first and second driving electrode layers, respectively, and a scanning waveform for the common electrode layer; adjusting at least one of the generated waveforms based on at least another one of the generated waveforms for at least one of cross-talk prevention or image quality adjustment; and placing the adjusted and generated waveforms on the respective electrode layers to concurrently drive the first and second display material layers while achieving said at least one of cross-talk prevention or image quality adjustment; wherein the controller is configured to generate a writing pulse for each of the first and second writing waveforms and a scanning pulse for the scanning waveform of a voltage sufficient for causing the respective display material layer being driven to change an initial optical state thereof, wherein the writing or scanning pulses of the waveforms corresponding to two adjacent electrode layers partially overlap each other in time, wherein said overlapped pulses include either a writing pulse with a scanning pulse or a writing pulse with a writing pulse; and based on an effective pulse width of the writing pulse or scanning pulse of the waveform corresponding to one of said two electrode layers, adjust an effective pulse width of the writing pulse or scanning pulse of the waveform corresponding to the other of said two electrode layers to drive, during a non-overlapping period of the writing or scanning pulses of the waveforms corresponding to said two electrode layers, the display material layer between said two electrode layers from the initial optical state to a target optical state corresponding to the image signals inputted for said display material layer.
