Description of the main elements
The following detailed description will further illustrate the invention in conjunction with the above-described figures.
Detailed Description
As shown in fig. 1, the electrochromic display device 100 includes a cover plate 10, an adhesive layer 20, a touch assembly 30, and an electrochromic assembly 40, which are sequentially stacked.
The cover plate 10 and the touch assembly 30 are bonded by the adhesive layer 20. The cover plate 10 may be made of glass, such as soda glass, aluminosilicate glass, alkali-free glass, etc. The cover plate 10 may also be made of transparent plastic or any other material with a certain light transmittance that can protect the structure to which it is attached. The Adhesive layer 20 is transparent, and may be an Adhesive having high light transmittance, such as a solid Clear Adhesive (OCA) or a Liquid Clear Adhesive (LOCA), so as not to affect the display effect.
The electrochromic assembly 40 includes a common electrode 41, an electrochromic layer 42, an electrolyte layer 44, an ion storage layer 46, and a thin film transistor substrate 48. The electrochromic layer 42 has opposite first and second sides 421 and 422. The electrolyte layer 44, the ion storage layer 46 and the thin film transistor substrate 48 are located on the first side 421. A plurality of common electrodes 41 are located on the second side 422. Electrolyte layer 44 is located between ion storage layer 46 and electrochromic layer 42. The ion storage layer 46 is located between the electrolyte layer 44 and the pixel electrode 484 of the thin film transistor substrate 48. The electrochromic assembly 40 is laminated in the order of a thin film transistor substrate 48, an ion storage layer 46, an electrolyte layer 44, an electrochromic layer 42, and a common electrode 41.
in another embodiment, the locations of electrochromic layer 42 and ion storage layer 46 may be interchanged. That is, electrolyte layer 44 is located between ion storage layer 46 and electrochromic layer 42. The electrochromic layer 42 is located between the electrolyte layer 44 and the pixel electrode 484 of the thin film transistor substrate 48. The electrochromic element 40 is laminated in this order of a thin film transistor substrate 48, an electrochromic layer 42, an electrolyte layer 44, an ion storage layer 46, and a common electrode 41.
the electrochromic layer 42 is an electrochromic material with electrochromic characteristics, and may be an inorganic electrochromic material, such as CeO2-TiO2, NiOx, WO3, MnO2, or an organic electrochromic material, such as bipyridyl salts, conductive polymers, metal-organic polymers, or metal phthalocyanine. The electrochromic layer 42 may exhibit a light-shielding (coloring) or transparent state by undergoing a redox reaction when a voltage applied between opposite sides thereof is changed.
Electrolyte layer 44 acts as an ion conducting layer to provide a channel for the transport of ions between electrochromic layer 42 and ion storage layer 46, but to block the passage of electrons. The electrolyte layer 44 may be prepared using a high molecular polymer solid electrolyte material.
The ion storage layer 46 is used to store ions and supply the ions needed during the color change process to balance the total amount of charge in the device. The ion storage layer 46 may also use an electrochromic material having properties opposite to those of the electrochromic material of the electrochromic layer 42 to function as a color overlay or complement. For example, the ion storage layer 46 may employ a cathodically reducible color change material and the electrochromic layer 42 may employ an anodically oxidized color change material.
The thin film transistor substrate 48 includes a substrate 482, a plurality of scanning lines GL provided on the substrate 482, a plurality of data lines DL, and a plurality of pixel units Px. Each of the scan lines GL extends in a first direction D1, each of the data lines DL extends in a second direction D2, and the first direction D1 crosses the second direction D2.
two adjacent scan lines GL and two adjacent data lines DL are insulatively crossed to define one pixel unit Px. The plurality of pixel units Px are arranged in a matrix in a plurality of rows and columns. Each pixel unit Px includes a pixel electrode 484 electrically connected to the electrochromic layer 42 and a thin film transistor 486, and the thin film transistor 486 is used for applying a driving signal on the data line DL to the pixel electrode 484 under the control of the scan line GL.
The plurality of pixel electrodes 484 are arranged in a matrix in rows and columns, and the pixel electrode 484 of each pixel unit Px is isolated from the pixel electrodes 484 corresponding to the other pixel units Px. The thin film transistor 486 includes a gate electrode GE, a source electrode SE, and a drain electrode DE. The gate electrode GE of the thin-film transistor 486 is electrically connected to a corresponding scanning line GL, the source electrode SE of the thin-film transistor 486 is electrically connected to a corresponding data line DL, and the drain electrode DE of the thin-film transistor 486 is electrically connected to the pixel electrode 484 of the corresponding pixel unit Px.
the data line DL is used for transmitting a driving signal to the thin film transistor 486. The scanning line GL is used to control the tft 486 to receive the driving signal. The driving signal is, for example, a voltage. In this way, the scanning line GL can control the on and off of the thin film transistor 486 of each pixel unit Px, so as to individually charge the pixel electrode 484 of each pixel unit Px, thereby achieving the purpose of individually applying a driving signal to the electrochromic layer 42 corresponding to each pixel electrode 484, and further enabling the electrochromic layer 42 corresponding to each pixel unit Px to generate the color change of different gray scales under the cooperation of the pixel electrode 484 and the common electrode 41.
in one embodiment, each pixel unit Px further includes a storage capacitor (not shown), and the drain DE of the thin film transistor 486 is electrically connected to one end of the storage capacitor, so as to solve the problem that the color stability cannot be maintained for a long time due to the leakage current existing inside the electrochromic device 40. The substrate 482 is used for carrying various elements of the tft substrate 486. Substrate 482 may be a transparent substrate 482, such as substrate 482 formed of glass, transparent plastic, or the like.
In one embodiment, the touch device 30 includes a first substrate 32, a plurality of touch sensing electrodes 34, a transparent insulating adhesive layer 35, a second substrate 36 and a common electrode 41. The touch sensing electrode 34 is located on a side of the common electrode 41 away from the electrochromic layer 42, and the touch sensing electrode 34 is arranged to be insulated and crossed with the common electrode 41. The first substrate 32 is located on a side of the touch sensing electrode 34 away from the common electrode 41. The touch sensing electrode 34 is formed on the surface of the first substrate 32. The second substrate 36 is located between the touch sensing electrode 34 and the common electrode 41. The common electrode 41 is formed on a surface of the second substrate 36. The transparent insulating adhesive layer 35 is located between the touch sensing electrode 34 and the second substrate 36. Each common electrode 41 is a rectangular strip extending along the first direction D1, the plurality of common electrodes 41 are disposed at intervals along the second direction D2, each touch sensing electrode 34 is a rectangular strip extending along the second direction D2, and the plurality of touch sensing electrodes 34 are disposed at intervals along the first direction D1. In other embodiments, the common electrode 41 and the touch sensing electrode 34 may have other conventional shapes and structures, for example, each common electrode 41 is a series formed by connecting a plurality of sub-common electrodes, and each touch sensing electrode 34 is a series formed by connecting a plurality of sub-touch sensing electrodes. Each sub-common electrode may be a diamond shape, a rectangular shape, or the like, and each sub-touch sensing electrode may be a diamond shape, a rectangular shape, or the like.
the common electrode 41 is time-division multiplexed as the touch driving electrode 38, and the common electrode 41 and the touch sensing electrode 34 are matched to realize touch sensing operation. The transparent insulating adhesive layer 35 and the second substrate 36 serve as a dielectric layer between the touch sensing electrodes 34 and the touch driving electrodes 38, so that the touch driving electrodes 38 and the touch driving electrodes 38 form a mutual capacitance type touch sensing structure. When a touch occurs, the capacitive coupling between the touch driving electrode 38 and the touch sensing electrode 34 corresponding to the vicinity of the touch point is affected, so that the sensing signal (e.g. voltage value) related to the mutual capacitance is changed, and the coordinates of each touch point can be calculated. In one embodiment, the first substrate 32 and the second substrate 36 may be rigid substrates such as glass and sapphire. In other embodiments, the first substrate 32 and the second substrate 36 may also be transparent flexible substrates, such as Polyimide (PI), polymethyl methacrylate (PMMA), Polycarbonate (PC), polyethylene Terephthalate (PET), and the like.
In one embodiment, in order not to affect the display effect, the common electrode 41 and the touch sensing electrode 34 are transparent, and the material thereof may be a conductive material such as a Metal Mesh (Metal Mesh), Indium Tin Oxide (ITO), Carbon Nanotube (Carbon Nanotube), or Nano Silver Wire (Nano Silver Wire). The transparent insulating Adhesive layer 35 may be, but not limited to, an Adhesive having high light transmittance, such as a solid Clear Adhesive (OCA) or a Liquid Clear Adhesive (LOCA).
In another embodiment, as shown in FIG. 2, the second substrate 36 can be omitted from the electrochromic display device 200. The touch assembly 30 includes a first substrate 32, a touch sensing electrode 34, a transparent insulating adhesive layer 35, and a common electrode 41. The touch sensing electrode 34, the transparent insulating glue layer 35 and the common electrode 41 are positioned on one side of the first substrate 32 close to the electrochromic layer 42. The transparent insulating adhesive layer 35 is disposed between the touch sensing electrode 34 and the common electrode 41 to electrically insulate the touch sensing electrode 34 from the common electrode 41. The common electrode 41 is time-division multiplexed as the touch driving electrode 38, and the common electrode 41 and the touch sensing electrode 34 are matched to realize touch sensing operation.
As shown in fig. 3, the present invention also provides a driving method applied to the above-described electrochromic display device 100, which includes applying a color-changing voltage for changing the color of the electrochromic layer 42 to the pixel electrode 484 and the common electrode 41 for a first period T1; in the second time period T2, the touch sensing electrode 34 and the common electrode 41 are loaded with touch signals. Wherein the first and second periods T1 and T2 are not overlapped in time, and the first and second periods T1 and T2 are alternately switched.
specifically, during the first time period T1, the touch-sensitive component 30 is not activated and the electrochromic component 40 is activated. In which a constant voltage is applied to the common electrode 41, and the voltage applied to the pixel electrode 484 is adjusted to cause the electrochromic layer 42 to change colors with different gray scales. Specifically, the scanning line GL controls the on and off of the thin film transistor 486 of each pixel unit Px, so as to individually charge the pixel electrode 484 of each pixel unit Px, and achieve the purpose of individually applying a driving signal to the electrochromic layer 42 corresponding to each pixel electrode 484, so that the electrochromic layer 42 corresponding to each pixel unit Px can generate color changes with different gray scales under the cooperation of the pixel electrode 484 and the common electrode 41.
In a second time period T2, the electrochromic device 40 is not activated and the touch device 30 is activated. Here, the voltage applied to the pixel electrode 484 is adjusted according to the voltage applied to the common electrode 41, so that the electrochromic layer 42 maintains a constant gray scale. When an object such as a finger or a stylus touches the cover 10, the capacitive coupling between the touch driving electrode 38 and the touch sensing electrode 34 corresponding to the vicinity of the touch point is affected, so that the sensing signal (e.g. voltage value) related to the mutual capacitance is changed, and the coordinates of each touch point can be calculated.
In summary, by time-sharing loading the color-changing voltage and the touch signal, the electrochromic display device 100 can have both touch and electrochromic functions, and when the electrochromic display device 100 displays a screen, not only the color of the whole display screen is changed, but also the driving signal can be independently applied to the electrochromic layer 42 corresponding to each pixel electrode 484, so that under the cooperation of the pixel electrode 484 and the common electrode 41, the electrochromic layer 42 corresponding to each pixel unit Px can generate color changes with different gray scales. As such, the electrochromic display device 100 has a wider application. For example, the electrochromic display device 100 can be used as a meeting room partition and can also be used as a whiteboard for writing; alternatively, when the electrochromic display device 100 is used as a smart window, a part of the see-through region and the like may be left.
in addition, the electrochromic display device 100 reuses the common electrode 41 of the electrochromic device 40 as the touch driving electrode 38 of the touch device 30, so that the advantages of reducing the thickness of the device, reducing materials, simplifying the manufacturing process and reducing the cost can be achieved under the condition of having both the electrochromic function and the touch function.
Although the present invention has been described in detail with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the spirit and scope of the present invention.
