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, the electrochromic material layer 133 is an organic electrochromic material, and if the electrochromic device 13 is the inorganic electrochromic device 13, the electrochromic 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 the display area 101 of base plate 1, if only display screen 4, then display screen 4 set up in on the display 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 the display area 101 of base plate 1, display screen 4 set up in on the touch-control screen 3.
