Abstract

A display panel with switchable single and double view fields, a control method, and a display device. The display panel includes a view field control box and a display control box. The view field control box has a plurality of sub-pixels, and the display control box has alternately arranged A plurality of first pixel units and a plurality of second pixel units, each sub-pixel corresponds to adjacent first pixel units and second pixel units; the transparent substrate of the field of view control box is provided with a first electrochromic layer, The second electrochromic layer, the dielectric layer and the black matrix, the first electrode for controlling the first electrochromic layer and the second electrode for controlling the second electrochromic layer are arranged on the transparent substrate, and the black matrix separates a plurality of sub-pixels And cover the gap between two adjacent first electrochromic layers, the projection of the second electrochromic layer on the display control box is located between the first pixel unit and the second pixel unit; the first electrochromic layer and the second electrochromic layer can be switched between transparent and black.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display panel with switchable single and double viewing fields, a control method and a display device. Background technique [0002] The existing dual-view display technology is mainly implemented by using a grating structure attached to the outside of the display panel. A slit grating is arranged in front of the display panel, and the slit grating includes alternately arranged light-shielding areas and light-transmitting areas; since the function of the slit grating is to make only a part of the display area of ​​the display panel visible in the left viewing area on the left side of the screen ( Including a plurality of first display areas), the right view area on the right side of the screen can only see another part of the display area of ​​the display panel (including a plurality of second display areas), wherein the first display area and the second display area alternate...
