Electro-wetting display unit and electro-wetting display system

Abstract

The invention provides an electro-wetting display unit and an electro-wetting display system. The electro-wetting display unit comprises a fluid layer, a dielectric layer and an electrode, wherein the fluid cavity comprises polar fluid, colored non-polar fluid and a partition wall used for surrounding the polar fluid and the non-polar fluid; the dielectric layer is positioned below the fluid cavity and is contacted with the non-polar fluid or the polar fluid in the fluid cavity; and the electrode is positioned below the dielectric layer. The electro-wetting display unit is characterized in that a hollow groove is arranged in the partition wall, is provided with an opening facing to the dielectric layer and is used for completely or partly storing the non-polar fluid when the voltage is applied between the polar fluid and the electrode. The electro-wetting display system comprises the electro-wetting display unit. When the electro-wetting display unit trends to be in the bright state in display, and the non-polar fluid paved above the dielectric layer originally enters the hollow groove by the assistance of the extrusion force on the non-polar fluid caused by the polar fluid controlled by the electrode, and is not attached at one corner or the middle area of the bottom surface.

Description

technical field [0001] The present invention relates to the field of display technology, in particular, the present invention relates to an electrowetting (electrowetting) display unit and an electrowetting display system. Background technique [0002] Electrowetting display is a new display technology emerging in recent years. Electrowetting display technology is more and more popular because of its characteristics of bistable display, good reflectivity, low power consumption, wide temperature range and fast enough response speed. Electrowetting display technology is still in its infancy, but its superior performance and development potential indicate that in the field of display technology in the future, electrowetting display will definitely occupy a place and become an important display method. [0003] Electrowetting display technology is a technology that controls the surface layer of the surrounded fluid by controlling the voltage to cause changes in the electrowetti...

AI Technical Summary

Problems solved by technology

However, when a voltage is applied between the polar fluid and the lower electrode for bright state display, as Figure 1b , 2b As shown by the arrows in and 3b, the non-polar fluid shrinks, but it still remains in the corners of the display pixels, making it impossible to achieve a completely uniform display when the bright state is displayed

Especially when it is used for black and white display, it cannot achieve a complete full white display, but black non-polar fluid can be seen in the corners, and the visibility of colored non-polar fluid in pixels will reduce the contrast and transmission of the display. rate, so that a good display effect cannot be achieved

That is, in the bright state, the non-polar fluid will also occupy a considerable area, thus affecting the display effect
