Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings and examples.
As shown in fig. 1-3, a self-chargeable touch display structure includes a substrate 1, atouch screen 3/a display screen 4 and a solar cell film 2, where the substrate 1 includes adisplay area 101 and anon-display area 102, thetouch screen 3/the display screen 4 is disposed on thedisplay area 101 of the substrate 1, and the solar cell film 2 is disposed on thenon-display area 102 of the substrate 1; thenon-display region 102 of the substrate 1 can be switched between a light-transmitting state and a light-shielding state.
The touch display structure switches thenon-display area 102 of the substrate 1 between a light transmitting state and a light shielding state, when thetouch screen 3/the display screen 4 is in a working state (for example, when the electronic device is on), thenon-display area 102 of the substrate 1 is switched to a light-shielding state, so that ambient light cannot penetrate through the substrate 1 and reach the solar cell film 2, when thetouch screen 3/display screen 4 is in a non-operating state (for example, when the electronic device is turned on), thenon-display area 102 of the substrate 1 is switched to a transparent state, so that ambient light can pass through the substrate 1 and reach the solar cell film 2, and since the power generation time of the solar cell film 2 is staggered with the operating time of thetouch screen 3/display screen 4, the electromagnetic signal generated by the solar cell film 2 during power generation does not affect the use of thetouch screen 3/display screen 4.
The substrate 1 is electrochromic glass, and an electrochromic device 13 is packaged in anon-display area 102 of the substrate.
The electrochromic device 13 includes a firsttransparent electrode layer 131 and a secondtransparent electrode layer 132 disposed opposite to each other, and anelectrochromic material layer 133 disposed between the first transparent electrode and the second transparent electrode in a stacked manner.
When current is introduced into the firsttransparent electrode layer 131 and the secondtransparent electrode layer 132, an electric field is formed between the firsttransparent electrode layer 131 and the secondtransparent electrode layer 132, and the electrochromic material turns into black or gray under the action of the electric field, so that a light-shielding state is presented; when current is not conducted to the firsttransparent electrode layer 131 and the secondtransparent electrode layer 132, an electric field is not formed between the firsttransparent electrode layer 131 and the secondtransparent electrode layer 132, and the electrochromic material becomes transparent in a natural state and is in a light-transmitting state.
In one embodiment, as shown in fig. 2, the electrochromic glass includes a first glass substrate 11 and a second glass substrate 12 which are oppositely arranged, and an encapsulation area is formed between the first glass substrate 11 and the second glass substrate 12 on thenon-display area 102; the electrochromic device 13 is encapsulated in the encapsulation area.
In this embodiment, if theelectrochromic material layer 133 uses a solid-state electrochromic material, such as tungsten trioxide, the encapsulation area does not need to be closed, and the encapsulation area may be a gap between the first glass substrate 11 and the second glass substrate 12; if theelectrochromic material layer 133 is made of a liquid electrochromic material, such as EC liquid, the encapsulation area needs to be sealed, a sealant located on the inner side and the outer side of thenon-display area 102 may be disposed between the first glass substrate 11 and the second glass substrate 12, so that theelectrochromic material layer 133 is sealed in a sealed cavity formed by the first glass substrate 11, the second glass substrate 12 and the sealant, or at least one of the first glass substrate 11 and the second glass substrate 12 may be provided with an encapsulation groove to accommodate and encapsulate theelectrochromic material layer 133.
Of course, if theelectrochromic material layer 133 is made of a solid-state electrochromic material, at least one of the first glass substrate 11 and the second glass substrate 12 may be provided with an encapsulation groove to accommodate and encapsulate theelectrochromic material layer 133, so as to reduce the overall thickness of the substrate 1.
In another embodiment, as shown in fig. 3, the substrate 1 includes a third glass substrate 14 and an electrochromic device 13, and the electrochromic device 13 is disposed between thenon-display region 102 of the third glass substrate 14 and the solar cell thin film 2.
In this embodiment, the electrochromic device 13 is directly fabricated on the third glass substrate 14, compared with the previous embodiment, one glass substrate 1 is omitted, the cost and the thickness are both small, but the electrochromic material can only be a solid-state electrochromic material.
The electrochromic device 13 is an organic electrochromic device 13 or an inorganic electrochromic device 13, if the electrochromic device 13 is the organic electrochromic device 13, theelectrochromic material layer 133 is an organic electrochromic material, and if the electrochromic device 13 is the inorganic electrochromic device 13, theelectrochromic material layer 133 is an inorganic electrochromic material.
This touch-control display structure can only touch-control screen 3 or display screen 4 also can have simultaneously touch-control screen 3 and display screen 4, if only touch-control screen 3, then touch-control screen 3 set up in on thedisplay area 101 of base plate 1, if only display screen 4, then display screen 4 set up in on thedisplay area 101 of base plate 1, if have simultaneously touch-control screen 3 and display screen 4, then touch-control screen 3 set up in on thedisplay area 101 of base plate 1, display screen 4 set up in on the touch-control screen 3.
The solar cell film 2 includes an anode layer disposed on the substrate 1, a semiconductor photovoltaic layer disposed on the anode layer, and a cathode layer disposed on the semiconductor photovoltaic layer.
The anode layer is a transparent anode and can be made of ITO materials, the cathode layer is preferably a metal cathode and can be made of materials such as silver, silver-copper alloy, aluminum or aluminum-molybdenum alloy and the like, so that ambient light penetrating through the semiconductor photovoltaic layer is reflected back to the semiconductor photovoltaic layer again, and the photoelectric conversion rate is improved.
