Embodiment Construction

[0023] The core idea of ​​the present invention is to provide a touch display device and its back cover. By introducing the electrochromic function into the back cover, the device can be made more colorful, and at the same time, the multi-touch function can be integrated into the back cover. On the board, through the cooperation of software, the user's finger operation position is displayed on the display interface, which is convenient for touch, can greatly break through the limitation of front touch, and can also make the device thinner and lighter.

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the ...

Abstract

The application discloses a touch display device and a back cover plate thereof. The back cover plate is characterized by comprising a transparent conductive layer arranged on the surface of a first substrate; an ion storage layer, an electrolyte layer and an electrochromism layer are orderly arranged at the upper part of the transparent conductive layer; a transparent sensor layer is arranged at the upper part of the electrochromism layer to receive touch information of a user; a second substrate is arranged at the upper part of the transparent sensor layer; the transparent conductive layer and the transparent sensor layer are used for providing voltage for the electrochromism layer; and the electrochromism layer is used for displaying different colors under different voltages. An electrochromism function is introduced into the back cover plate so that the device is more colorful; and meanwhile, a multi-point touch function is integrated on the back cover plate, a user finger operation direction is displayed on a display interface through the cooperation of the software, the touch is convenient, the limitation of the frontage touch can be greatly broken through, and the device can be lighter and thinner.

Description

technical field [0001] The invention belongs to the technical field of consumer electronics products, and in particular relates to a touch display device and a rear cover thereof. Background technique [0002] In traditional touch display products such as mobile phones, tablets, etc., the back cover is mainly used for protection and does not integrate any other functions. Users cannot perform any operations on the back cover, and cannot control the space of the back cover effective use, which leads to waste. [0003] With the improvement of living standards, people have higher and higher requirements for touch display devices. For example, in some cases, when people hold a large-screen mobile phone with one hand, it is not easy to achieve one-hand touch operation. Trouble, because when holding the mobile phone with one hand, the fingers are in contact with the back cover of the mobile phone, so people are more inclined to use the back cover to perform related touch operatio...
