Embodiment Construction

[0028] The projection display device and projection method thereof of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0029] Such as Figure 2 to Figure 4 As shown, the projection display device of the present invention includes an emitter 10 and a reflector 14, wherein the emitter 10 is composed of a light source 11 integrating red, green, and blue small lamps and a convex lens respectively positioned at the front and back of the light source 11 12. Composed of a concave mirror 13, the light source 11 is located at the focal point of the convex lens 12, and the rear concave mirror 13 can ensure that most of the beam energy of the three-color light source 11 is emitted. The switch and brightness of the three small lamps in the light source 11 are controlled by the micro control unit. According to the principle of three primary colors and under the coordination of the micro control unit, the emitter 10 can combine...

Abstract

The invention relates to a projection display device and a projection method thereof, the projection display device comprises an emitter, a reflecting unit, a focuser, a micro-control unit and a decoding unit, wherein the reflecting unit reflects light beams emitted by the emitter, the focuser is located between the emitter and the reflecting unit, the micro-control unit controls the emitter and the reflecting unit, and the decoding unit provides projection information to the micro-control unit. The projection display device and the projection method thereof reduce the volume of the projection display device, and adjust the emitter through a microcontroller simultaneously, thereby simplifying operation, and guaranteeing effects of display definition, color saturation, illumination and the like.

Description

technical field [0001] The present invention relates to a projection display device and its projection method, in particular to a portable projection display device and its projection method. Background technique [0002] Currently, consumer electronics are increasingly miniaturized, and powerful, low-power, and portable devices have always been the dream of consumers. High definition, high color fidelity, large area display technology is a crucial part of it. However, the current devices all exist in miniaturization and poor display effect, and better display effect and bulky size, so they can only be handled as a compromise between volume and effect. [0003] The basic structure diagram of the current projection display device is as follows: figure 1 As shown, the current projection display device includes a light source 1, a liquid crystal screen 2 and a lens 3 in sequence. The beam of light passes through the liquid crystal screen 2, and under the action of the combin...
