Multi-level gray scale electrowetting driving method and system

Abstract

The invention discloses a multi-level gray scale electrowetting driving method. The method comprises steps that the ink power-on time is divided by a system into N time slots, in the first time slot,the ink is controlled for being in a tiled state; from the second time slot to the Nth time slot, based on the linear relationship when the ink is initially powered on, voltage driving is respectivelycarried out by the system to achieve the target gray scale. A multi-level gray scale electrowetting driving system comprises a first time slot control module and other time slot control modules. In the first time slot, the ink is controlled for being in the tiled state; from the second time slot to the Nth time slot, based on the linear relationship when the ink is initially powered on, voltage driving is carried out by the system to achieve the target gray scale, and electrowetting to display 16 gray scales can be achieved. The method is advantaged in that the linear relationship between thevoltage and reflectivity in the wetting power-on process is utilized, the brand new electrowetting driving mode is realized, and the method is widely applied to the electrowetting field.

Description

technical field [0001] The invention relates to the field of electrowetting, in particular to a multi-level grayscale electrowetting driving method and system. Background technique [0002] Electrowetting display is a new display technology that has emerged in recent years. When an electric field is not applied to an electrowetting display, the colored polar liquid in each pixel covers the entire pixel unit; when an electric field is applied, the inside of each pixel The colored polar liquid shrinks, enabling the color of the pixel substrate to be seen. At present, electrowetting displays have attracted international attention, because of the characteristics of low power consumption, fast refresh time, and reflective display of electrowetting displays, it is possible for electronic paper to achieve the display characteristics of current liquid crystal displays. [0003] The existing technology is aimed at the modulation of electrowetting gray scale by determining the apertu...

AI Technical Summary

Problems solved by technology

[0005] 1. The cycle of the control voltage is too large, and the linear relationship of the ink at the moment of power-on is not well utilized;

[0006] 2. There are few gray scales that can be realized, and the existing voltage cycle control can only achieve 4 gray scales;

[0007] 3. The driver chip of the existing electrophoretic display can only output three voltages: -15V, 0V and +15V
