Problems solved by technology
The existing active matrix electrowetting display devices are driven by PWM (Pulse width modulation, pulse width modulation) waveform, which is characterized by easy implementation of the driving system and convenient design of the driving waveform, but it is difficult to design the drive according to the electrowetting characteristics of the PWM waveform. , resulting in slow response time and unstable ink in the electrowetting display. The lower the modulation frequency, the longer the driving time of the display gray scale, which makes the response time of the electrowetting display slower and the display gray machine in this driving waveform. The stability of the display device is not good, resulting in quality problems of the display device

The invention discloses an electrowetting display driving method, a display, a device and a storage medium. It relates to the display field, wherein the method drives the ink in stages through a gray-scale driving waveform, wherein the gray-scale driving waveform includes a plurality of sub-frame driving waveforms, and in each stage, a sub-frame driving waveform is used to drive the ink to obtain a sub-image frame, Then obtain a plurality of sub-image frames, and combine the plurality of sub-image frames into a complete image frame. Using the hysteresis effect in the electrowetting characteristics to design the electrowetting driving waveform, compared with the existing electrowetting display, it can reduce the response time of the grayscale display of the electrowetting display device, and improve the response time of electrowetting and electrowetting. Grayscale stability, improving display quality with electrowetting.
Description
technical field [0001] The invention relates to the display field, in particular to an electrowetting display driving method, a display, a device and a storage medium. Background technique [0002] In recent years, electrowetting display technology has developed rapidly and gradually occupied more market share. Electrowetting display devices have the characteristics of high contrast, suitable for reading, convenient and light, foldable and bendable, and low energy consumption. The existing active matrix electrowetting display devices are driven by PWM (Pulse width modulation, pulse width modulation) waveform, which is characterized by easy implementation of the driving system and convenient design of the driving waveform, but it is difficult to design the drive according to the electrowetting characteristics of the PWM waveform. , resulting in slow response time and unstable ink in the electrowetting display. The lower the modulation frequency, the longer the driving time of...
