Problems solved by technology
[0005] However, the reflective electrowetting display technology in the prior art can only achieve black and white display without the cooperation effect of color filters, and the display effect is very limited; while color display requires additional color filters, and the structure is more complicated. Complexity, which limits the further development of reflective electrowetting display technology

An embodiment of the present invention provides a display panel, which relates to the field of display technology, and can achieve color display without a backlight source or a color filter layer. The display panel includes: a pixel isolation wall arranged between the first and second substrates, and the pixel isolation wall divides the space between the first and second substrates into a plurality of sub-pixel regions; The space between the substrate and the second substrate is sequentially provided with a first electrode, a first fluid layer, a second fluid layer, a hydrophobic medium layer, a second electrode, and a black light-absorbing layer; the first fluid layer is composed of a transparent hydrophilic liquid; The second fluid layer is made of colored ink; when there is no electric field between the first and second electrodes, the second fluid layer spreads on the surface of the hydrophobic medium layer; when an electric field is formed between the first and second electrodes Next, the second fluid layer is brought together to expose the hydrophobic medium layer. Used in the preparation of display panels.
Description
technical field [0001] The present invention relates to the field of display technology, in particular to a display panel. Background technique [0002] Electrowetting (Electro Wetting on Dielectric, EWOD) refers to the phenomenon that the surface tension of the liquid on the solid surface is changed by adjusting the voltage applied between the liquid and the solid electrode, thereby changing the contact angle between the two. In recent years, droplet driving and control technology based on the electrowetting effect on the medium has attracted widespread attention and has been applied to the field of flat panel display. [0003] At present, electrowetting display technology is mainly divided into two types: reflective and passive light emitting. Reflective electrowetting display technology mainly controls the grayscale by shrinking and expanding the black ink covered on the white reflective electrode under voltage control to achieve black and white display; or, on the basis...
