Abstract:
1. A portable terminal device comprising: a display screen; a pico projector for receiving an image signal of a predetermined format and projecting an image light onto the display screen according to the image signal of the predetermined format, so that an image corresponding to the image signal of the predetermined format is displayed on the display screen; and a main body part, for fixing the display screen and the pico projector, the main body part comprising a first part, a second part and a hinge part, the display screen is fixed on the first part; wherein the pico projector is positioned at an edge of the display screen, wherein the first part and the second part is hinged by the hinge part, so that the first part is rotatable with respect to the second part, in order to form a predetermined angle between the pico projector and the display screen while projecting, wherein the image light projected by the pico projector is ultraviolet light or blue light near ultraviolet; on the display screen, a first fluorescent material for generating a first primary color light visible to human eyes, a second fluorescent material for generating a second primary color light visible to human eyes, and a third fluorescent material for generating a third primary color light visible to human eyes are coated; and the first fluorescent material is hit by the ultraviolet light or the blue light near ultraviolet projected from the pico projector to generate the first primary color light, the second fluorescent material is hit by the ultraviolet light or the blue light near ultraviolet projected from the pico projector to generate the second primary color light, and the third fluorescent material is hit by the ultraviolet light or the blue light near ultraviolet projected from the pico projector to generate the third primary color light, and the first primary color light, the second primary color light and the third primary color light are used to synthesize the image corresponding to the image signal of the predetermined format.
