Abstract

The invention discloses electronic paper, and belongs to the technical field of display. The electronic paper comprises an array substrate, a cover plate and an electrophoresis layer. The first auxiliary electrode in the array substrate is electrically connected with the pixel electrode, so that the first auxiliary electrode is also equivalent to the pixel electrode. Therefore, when the electronic paper is used for displaying, the first auxiliary electrode and the second auxiliary electrode can form a first storage capacitor, and the pixel electrode and the second auxiliary electrode can form a second storage capacitor. The first storage capacitor and the second storage capacitor are connected in parallel, and the total storage capacitance value in the array substrate is the sum of the capacitance value of the first storage capacitor and the capacitance value of the second storage capacitor. Compared with the prior art, the electronic paper provided by the embodiment of the invention has the advantages that the capacitance value of the storage capacitor is increased, the stability of the voltage loaded on the pixel electrode is improved, and the display effect of the electronic paper is further improved.

Description

technical field [0001] The present application relates to the field of display technology, and in particular, to an electronic paper. Background technique [0002] Electronic paper is a new type of display device, which is mainly used in electronic labels, billboards and electronic readers. The display effect of the electronic paper is close to that of natural paper, which can reduce visual fatigue during reading. [0003] In the related art, electronic paper may generally include: an array substrate and a cover plate arranged oppositely, and an electrophoretic layer located between the array substrate and the cover plate. The array substrate has a plurality of pixels arranged in an array, and each pixel may include a pixel electrode and an auxiliary electrode insulated from the pixel electrode. The pixel electrode and the auxiliary electrode can form a storage capacitor during display, so as to maintain the stability of the voltage loaded on the pixel electrode. [0004]...
