[0043] The electronic ink screen 32 is generally composed of two substrates, on which is coated an electronic ink composed of countless tiny transparent particles. The particles are formed by many black and white particles with positive and negative charges sealed in liquid microcapsules. Charged particles of different colors will move in different directions due to the different applied electric fields, presenting a black or white effect on the surface of the display screen. Through the above process, black and white patterns and texts like printed objects can be displayed on the display screen. After the electronic ink screen 32 is powered off, the picture on its display screen can still be retained, so it has the advantage of saving power. The pattern of the electronic ink screen 32 can be changed by only briefly connecting the power circuit. In some embodiments, the electronic ink screen 32 is set as an electronic ink screen 32, and the decorative effect of the protective shell 10 of the portable mobile terminal is achieved by switching the pattern displayed by the electronic ink screen 32.
