Abstract

An electrowetting display device includes an electrowetting display panel and an illumination unit. The electrowetting display panel includes two or more different optical color-converting liquid layers and a plurality of light-shielding liquid layers. The two or more different optical color-converting liquid layers are able to convert the light source generated by the illumination unit into light beams having two or more different colors of desired grey scales. The light-shielding liquid layers can be driven to change the transmittance of display regions so as to implement switch between transparent display mode, non-transparent display mode and semi-transparent display mode.

Description

technical field [0001] The invention relates to a switchable transparent electrowetting display device, in particular to a switchable transparent electrowetting display device which can independently control the transparency and the grayscale brightness value of pixels. Background technique [0002] The electrowetting display device (electrowetting display device) has become one of the key points of the research and development of the display technology industry due to its advantages of no need to install polarizers and high aperture ratio. Please refer to figure 1 . figure 1 A schematic diagram of a known electrowetting display device is shown. Such as figure 1 As shown, a known electrowetting display device 10 includes an electrowetting display panel 20 and a backlight module 30 . The electrowetting display panel 20 includes two transparent substrates 21 and 22 oppositely arranged, and a polar aqueous solution 23, a hydrophobic dielectric layer 24, a transparent electr...
