The invention relates to the field of touch, and provides a touch device and a manufacturing method of the touch device. The touch device comprises a pixel unit and a touch unit. An electrochromism layer, a pixel electrode and a thin-film transistor serving as a pixel electrode switch are arranged inside arranged the pixel unit. The pixel electrode is connected with the electrochromism layer. The touch unit comprises a touch drive electrode and a touch sensitive electrode, wherein the touch drive electrode and the touch sensitive electrode are arranged in an intersecting and insulating mode, and the touch unit is used for acquiring a touch position. The thin-film transistor is used for controlling the pixel electrode to work according to the acquired touch position so as to apply a drive signal to the electrochromism layer connected with the pixel electrode. According to the touch device, the touch unit is used for acquiring the touch position, the color of the position, corresponding to the touch position, of the electrochromism layer inside the pixel unit is changed according to the touch position, and therefore color changes of a touch screen are increased. The touch position is acquired through the touch unit, and therefore the position, corresponding to the touch position, of the electrochromism layer can be controlled to conduct color changes.
Description
technical field [0001] The invention relates to the touch field, in particular to a touch device and a manufacturing method thereof. Background technique [0002] In recent years, electrochromic glass has been very active in the application and development of smart windows. This device consisting of basic glass and electrochromic system utilizes the light transmission properties of electrochromic materials under the action of an electric field. Adjustability, can achieve the purpose of adjusting the light intensity according to people's wishes. The use of electrochromism can selectively absorb or reflect external heat radiation and prevent internal heat diffusion, thereby saving energy consumption. [0003] The mainstream of existing touch screens is based on liquid crystals or light emitting diodes, but these touch screens have high power consumption, complex structures, and high manufacturing costs. Contents of the invention [0004] In order to solve the defect of hig...
