Problems solved by technology

This kind of protective cover is only used as the outer protection of portable devices, and has no other special circuit functions
In addition, for the flip-type touch screen protective cover, the user must lift the cover before performing touch operations on the touch screen during use, and the process of opening the cover will inevitably make the portable device extra extend. Protective cover increases overall bulk and reduces convenience of hand-held portable device

Embodiment Construction

[0045] figure 1 Shown is a schematic diagram of a conductive color-changing element structure. Please refer to figure 1 The conductive color changing element 100 in the present invention is, for example, an ion storage layer 104, an electrolyte layer 106, and an electrochromic layer 108 stacked between the upper and lower transparent conductive substrates (102a and 102b). The transparent conductive substrates 102a and 102b are respectively electrically connected to a power source 110. It is worth noting that when a voltage difference (for example, 1.5-2 volts) is applied to the transparent conductive substrate 102a and 102b to energize the conductive color changing element 100, the electrochromic layer 108 will produce a reversible chemical change due to the flow of current. For example, it is an oxidation-reduction reaction, so that the electrochromic layer 108 changes its light transmittance. When the power is turned off and no power is supplied, the light transmission coeff...

Abstract

A color-changeable protective device for a portable device equipped with a touch screen is provided. The color-changeable protective device comprises a power source and a electro-chromic element. The electro-chromic element is disposed to correspond to the touch screen so as to cover the entire touch screen. According to whether the operating status of the electro-chromic element is a power-on operating status, the electro-chromic element appears to be transparent or opaque.

Description

Technical field [0001] The invention relates to a protection device and a portable device, and more particularly to a color change protection device for protecting the portable device. Background technique [0002] Generally, portable devices, such as smart phones, personal digital assistants (PDAs), portable digital multimedia players, and tablet computers are gradually moving towards the goal of being lighter, thinner, and convenient to carry. In addition, with the increasing development of touch panel technology, most of today's portable devices are developing in the direction of using a touch screen as a user operation interface. Since the portable device is very light and thin, a protective case (or protective case) is needed to protect the outer layer to avoid accidental breakage or damage, and the touch screen needs a protective cover. Prevent the touch screen from being hit and scratched by non-input devices when the user carries the portable device. [0003] The material...
