Abstract

The invention discloses an electrowetting display screen and a vehicle speed prompting screen based on electrowetting display. The electrowetting display screen comprises a top conductive board, at least one first electrowetting display front panel unit, a second electrowetting display front panel unit, and a driving unit. The top conductive board, the at least one first electrowetting display front panel unit, and the second electrowetting display front panel unit are successively arranged from top to bottom. The driving unit is used for driving the at least one first electrowetting display front panel unit and the second electrowetting display front panel unit and controlling a display timing sequence. The electrowetting display screen switches different display effects by controlling the display area of the electrowetting display front panel unit in each layer and controlling the display timing sequence of the electrowetting display front panel units in multiple layers. The invention also discloses the vehicle speed prompting screen based on electrowetting display. The vehicle speed prompting screen based on electrowetting display has characteristics of high visibility, low power consumption, and fast response speed. The electrowetting display screen can be widely used in display technical field.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an electrowetting display screen and a vehicle speed prompt screen based on the electrowetting display. Background technique [0002] Electrowetting display (Electrowetting display) technology is a reflective "paper-like" display technology based on voltage-controlled interfacial movement between colored non-polar oil and polar liquid. When no voltage is applied, The ink spreads on the surface of the hydrophobic layer, revealing the color of the ink. When a voltage is applied, the ink contracts, revealing the color of the underlying substrate. This display technology has the characteristics of good outdoor visibility (especially in strong light environment), fast switching response, low energy consumption, rich color schemes, etc., and has excellent application potential. [0003] At present, common prompt screens are mainly based on technologies such as LED or LCD, which are ...
