Embodiment 1

[0034] figure 1 is a schematic plan view of the array substrate in Embodiment 1 of the present invention, figure 2 It is a schematic plan view of the field of view control box in Embodiment 1 of the present invention, image 3 It is a schematic diagram of the structure of the display panel in the dual field of view mode in Embodiment 1 of the present invention, Figure 4 It is a schematic diagram of the optical path of the display panel in the dual field of view mode in Embodiment 1 of the present invention, Figure 5 It is a schematic structural diagram of the display panel in the single field of view mode in Embodiment 1 of the present invention, Image 6 is a schematic plan view of the dielectric layer in Embodiment 1 of the present invention.

[0035] like Figure 1 to Figure 6 As shown, a display panel with switchable single and double view fields provided by Embodiment 1 of the present invention includes a view field control box 10 and a display control box 20 arran...

Embodiment 2

[0063] Figure 7 It is a schematic diagram of the structure of the display panel in the second embodiment of the present invention when it is in a dual-field mode. like Figure 7 As shown, the display panel with switchable single and double viewing fields provided by Embodiment 2 of the present invention is the same as Embodiment 1 ( Figure 1 to Figure 6 ) in the single and double view field switchable display panels are basically the same, the difference is that, in this embodiment, the black matrix 114 and the second electrochromic layer 116 are located on the same side of the second electrode 115, preferably, Both the black matrix 114 and the second electrochromic layer 116 are located on the side of the second electrode 115 facing the dielectric layer.

[0064] Further, the second electrochromic layer 116 is correspondingly disposed under the first electrochromic layer 112 , and the second electrochromic layer 116 is not disposed at the black matrix 114 , thereby reduci...

Abstract

The invention discloses a display panel with switchable single and double fields of view, a control method and a display device. The display panel comprises a view field control box and a display control box, the view field control box is provided with a plurality of sub-pixels, the display control box is provided with a plurality of first pixel units and a plurality of second pixel units, the first pixel units and the second pixel units are alternately arranged in the first direction, and each sub-pixel corresponds to the adjacent first pixel unit and second pixel unit; a transparent substrate of the view field control box is provided with a first electrochromic layer, a second electrochromic layer, a dielectric layer and a black matrix. A first electrode for controlling the first electrochromic layer and a second electrode for controlling the second electrochromic layer are arranged on the transparent substrate; the black matrix separates the plurality of sub-pixels and shields a gapbetween two adjacent first electrochromic layers, and the projection of the second electrochromic layer on the display control box is located between the first pixel units and the second pixel units;the first electrochromic layer and the second electrochromic layer are switchable 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...
