Problems solved by technology

exist figure 1 Among them, the electrolyte layer 4 is a solid electrolyte, since the electrochromic layer 3 and the electrolyte layer 4 are both solid, so there will be no crosstalk between pixels, but the solid electrolyte contains a polymer, and the ion conduction rate is relatively slow. The response time of the device is slow, which affects the display effect
[0005] like figure 2 As shown, in another structure of the existing electrochromic display device, the electrolyte layer 4 is a liquid electrolyte, which does not contain polymers, ion conduction is not hindered, and the response time is relatively figure 1 The electrochromic display device shown in is fast, but it is prone to crosstalk between pixels

Embodiment 1

[0037] This embodiment provides an electrochromic display device, which has the advantages of simple structure, no crosstalk between pixels, and fast response speed.

[0038] like image 3 As shown, the electrochromic display device includes a first substrate 1 and a second substrate 2 arranged oppositely, an electrochromic layer 3 and an electrolyte layer 4 are arranged between the first substrate 1 and the second substrate 2, and the electrochromic An isolation layer 7 is provided between the layer 3 and the electrolyte layer 4, and the isolation layer 7 is formed by a material that allows the cations in the electrolyte layer 4 to pass through, while blocking the passage of anions and molecules. In this embodiment, the electrochromic display device is packaged by the outer frame 6 to form a whole. Since a liquid electrolyte is used, such as Figure 7 As shown, the electrolyte in it can provide the transport channel for the ions required by the electrochromic effect, which m...

Embodiment 2

[0055] This embodiment provides an electrochromic display device, compared with Embodiment 1, such as Figure 6 As shown, in the electrochromic display device in this embodiment, an isolation layer is still provided between the electrolyte layer and the electrochromic layer, but no barrier wall may be provided between the sub-pixels.

[0056] Wherein, the material of the isolation layer is the same as that of the embodiment 1, and the principle of forming the electrochromism between the electrolyte layer and the electrochromic layer is the same as that of the embodiment 1, and will not be described in detail here.

[0057] In the electrochromic display device of this embodiment, perfluorosulfonic acid resin is used to form the isolation layer, so that the electrolyte layer and the electrochromic layer are effectively isolated and the channel for the smooth flow of cations is maintained, which effectively solves the problem of electrochromic The problem that the material will b...

Embodiment 3

[0059] This embodiment provides a display device, which adopts the electrochromic display device in Embodiment 1 or Embodiment 2.

[0060] The display device may be any product or component with a display function, such as electronic paper, mobile phone, tablet computer, television, monitor, notebook computer, digital photo frame, and navigator.

[0061] Since the display device of this embodiment adopts the electrochromic display device in Embodiment 1 or Embodiment 2, the structure is simple, and the isolation layer makes the electrochromic layer and the electrolyte layer well isolated, so it can effectively avoid The electrochromic material is dissolved in the liquid electrolyte and maintains normal ion channels to ensure the stable display effect of the electrochromic display device.

Abstract

The invention belongs to the technical field of display and particularly relates to an electrochromic display device and unit. The electrochromic display device comprises a first substrate and a second substrate which are opposite. An electrochromic layer and an electrolyte layer are disposed between the first substrate and the second substrate. An isolation layer is discoed between the electrochromic layer and the electrolyte layer. The isolation layer is made of material which allows the positive ions in the electrolyte layer to pass and stops negative ions and molecules to pass. The electrochromic display device is fast in response, free of crosstalk among pixels and good in display effect.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to an electrochromic display device and a display device. Background technique [0002] Electrochromic (electrochromic) refers to the phenomenon that the optical properties of materials (reflectivity, transmittance, absorptivity, etc.) undergo stable and reversible color changes under the action of an external electric field. Change; materials with electrochromic properties are called electrochromic materials. [0003] Currently, display devices formed using electrochromic materials have appeared. Due to the bistable performance of electrochromic materials, electrochromic display devices made of electrochromic materials not only do not require backlights, but also do not consume power as long as the display content does not change after displaying static images, reaching The purpose of energy saving. In addition, compared with other display devices, the electrochromi...
