Example 1
As shown in fig. 1, the present embodiment provides an electrochromic display including: anelectrochromic component 1; thedimming component 2 is positioned on one side of theelectrochromic component 1, which is far away from the light-emitting side of theelectrochromic component 1, and thedimming component 2 is suitable for switching between a transparent state and a reflecting state; thelight source 3 is arranged on one side, away from theelectrochromic component 1, of thedimming component 2, thelight source 3 is suitable for being in an on state when thedimming component 2 is switched to a transparent state, and thelight source 3 is suitable for being in an off state when thedimming component 2 is switched to a reflecting state.
In the electrochromic display, when the external light is weak or no external light exists, thelight source 3 is in an on state and thedimming component 2 is switched to a transparent state, and light emitted by thelight source 3 is irradiated onto theelectrochromic component 1 through thedimming component 2, so that a display image is generated on a light emitting side; when the external light is stronger, thelight source 3 is in a closed state and thedimming component 2 is switched to a reflection state, the external light irradiates thedimming component 2 through theelectrochromic component 1, and then the external light is emitted out through theelectrochromic component 1 after being reflected by thedimming component 2, so that a display image is generated on a light emitting side. Namely, the electrochromic display can ensure good display effect under different external light intensities by controlling thedimming component 2 to switch between the transparent state and the reflective state and controlling thelight source 3 to be turned on and off.
In this embodiment, thelight adjusting component 2 is an atomizing glass or a light adjusting film; thedimming component 2 comprises a third substrate, a third transparent conductive layer, a liquid crystal layer, a fourth transparent conductive layer and a fourth substrate which are stacked, wherein the third substrate is made of, but not limited to, glass or polyimide, and the fourth substrate is made of, but not limited to, glass or polyimide; specifically, when the third substrate and the fourth substrate are made of glass, thedimming component 2 is made of atomized glass; when the third substrate and the fourth substrate are made of polyimide, thelight adjusting assembly 2 is a light adjusting film.
Further, thedimming component 2 is adapted to be in a transparent state when the brightness of the external light is lower than the threshold, and thedimming component 2 is adapted to be in a reflective state when the brightness of the external light is higher than the threshold. Specifically, the threshold is 30lux to 100lux, and a specific threshold can be selected according to actual needs.
In the present embodiment, thelight source 3 includes, but is not limited to, a white light source. Furthermore, thelight source 3 is arranged on one side of thedimming component 2, which is far away from theelectrochromic component 1, so that the light emitted by the electrochromic display cannot be shielded, and the flexible setting mode is achieved. Preferably, thelight source 3 is a whole-surface light-emitting light source, and the whole-surface light-emitting light source can make the brightness and the contrast of the electrochromic display at different positions the same, so that the display effect is more uniform.
In this embodiment, the electrochromic display further comprises a control module (not shown in the figure) electrically connecting thedimming component 2 and thelight source 3, the control module being adapted to control thedimming component 2 to switch between a transparent state and a reflective state; the control module is further adapted to control the switching of thelight source 3.
Specifically, when the external light is strong, the control module controls thelight source 3 to be turned off and controls thedimming component 2 to be switched to a reflective state, so that the electrochromic display is a reflective display, the external light irradiates thedimming component 2 through theelectrochromic component 1, and is reflected by the dimmingcomponent 2 and then emitted through theelectrochromic component 1, so that a display image is generated on a light emitting side; when the brightness of a display image generated by the reflective display is low or the reflective display cannot generate the display image, the control module controls thelight source 3 to be turned on and switches thedimming component 2 to be in a transparent state, so that the electrochromic display is a transmissive display, and light emitted by thelight source 3 is irradiated onto theelectrochromic component 1 through thedimming component 2, so that the display image is generated on a light emitting side.
It is to be understood that theelectrochromic element 1 functions as a filter. Take the example that the electrochromic display needs to show blue light. When the electrochromic display is a reflective display, external light irradiates to theelectrochromic component 1 and then is filtered by theelectrochromic component 1 to remove light with non-blue wave bands, so that the light irradiating to thedimming component 2 is blue light, and the blue light irradiates to the surface of theelectrochromic component 1 after being reflected by the dimmingcomponent 2 and then emits the blue light on the light emitting side. When the electrochromic display is a transmissive display, light emitted by thelight source 3 is irradiated onto theelectrochromic component 1 through thedimming component 2, and then the light in a non-blue waveband is filtered by theelectrochromic component 1, so that light emitted from the light emitting side is blue light. That is, the display color of the electrochromic display is controlled by theelectrochromic assembly 1.

Specifically, the material of the first substrate 11 includes, but is not limited to, glass or polyimide, and the material of the second substrate 16 includes, but is not limited to, glass or polyimide; the material of the first transparent conductive layer 12 includes, but is not limited to, Indium Tin Oxide (ITO), nano silver wire or graphene, and the material of the second transparent conductive layer 15 includes, but is not limited to, Indium Tin Oxide (ITO), nano silver wire or graphene; the electrochromic layer 13 is made of a solid electrochromic material, specifically including an organic electrochromic material, an inorganic electrochromic material and an organic-inorganic hybrid electrochromic material, and the material of the electrochromic layer 13 can be selected according to a display color; the material of the electrolyte layer 14 is a liquid electrolyte, a solid electrolyte or a gel electrolyte, and the electrolyte layer 14 is ion-exchanged with the electrochromic layer 13, so that the electrolytic rate of the electrolyte layer 14 is related to the display capability of the electrochromic layer 13, and the electrolytic rate of the liquid electrolyte is greater than that of the gel electrolyte than that of the solid electrolyte, however, the encapsulation process of the liquid electrolyte is complicated, and therefore the material of the electrolyte layer 14 is preferably a gel electrolyte.
As shown in fig. 1, as an alternative embodiment, afirst antireflection film 17 is disposed on a surface of thefirst substrate 11 facing the first transparent conductive layer 12 and/or a surface of thefirst substrate 11 facing away from the first transparent conductive layer 12, where thefirst antireflection film 17 can improve transmittance of light incident on the surface of thefirst substrate 11, so as to improve brightness of the electrochromic display; and/or asecond antireflection film 18 is arranged on the surface of the second substrate 16 facing the secondtransparent conducting layer 15 and/or the surface of the second substrate 16 facing away from the secondtransparent conducting layer 15, and when the electrochromic display is a transmissive display, the transmittance of light from thelight source 3 to the second substrate 16 can be improved by the arrangement of thesecond antireflection film 18, so that the brightness of the electrochromic display is improved. That is, the arrangement of thefirst antireflection film 17 and thesecond antireflection film 18 can improve the display effect of the electrochromic display.
Further, as shown in fig. 1, when afirst antireflection film 17 is disposed on a surface of thefirst substrate 11 away from the first transparent conductive layer 12, atransparent protection layer 19 may be further disposed on a surface of thefirst antireflection film 17 away from thefirst substrate 11 to protect thefirst antireflection film 17 and prevent thefirst antireflection film 17 from being damaged. Specifically, the material of thetransparent protection layer 19 includes, but is not limited to, silicone-polyurea, silicone-polyurethane-polyurea, and silicone polyamide.
As an alternative embodiment, as shown in fig. 2, theelectrochromic layer 13 includes a plurality ofelectrochromic regions 131; theelectrolyte layer 14 comprises a plurality ofelectrolyte regions 141 corresponding to theelectrochromic regions 131, andisolation columns 142 are arranged between theadjacent electrolyte regions 141; both the first transparent conductive layer 12 and the second transparentconductive layer 15 are patterned to conform to theelectrochromic region 131 and theelectrolyte region 141. The above arrangement divides theelectrochromic assembly 1 into a plurality of display areas, and the colors displayed in the respective display areas may be the same or different, depending on the choice of the materials of the respectiveelectrochromic areas 131.
Further, severalelectrochromic regions 131 may be grouped, with adjacent 2 x 2 arrays in a group, with 4electrochromic regions 131 in each group displaying the four colors cyan, magenta, yellow, and black, respectively. The material of eachelectrochromic region 131 is a monochrome electrochromic material to improve controllability of display colors.
