Digital projection device capable of realizing ultra-definition replay

Abstract

The invention discloses a digital projection device capable of realizing ultra-definition replay. According to the digital projection device, image data is firstly processed by an image data processing module, a RGB (Red Green Blue) data separation module, a RGB data D/A (Digital-to-Analog) conversion module, an X/Y separation processing module, an X/Y phase synchronizing module, a three-base-color LED (light-emitting diode) drive circuit, a RGB brightness control circuit and a projection head drive circuit to be converted to an optical image, and then the optical image is projected by a laser LED lamp. Since the original data is processed in the entire process, the situation of distortion or loss of the data can be avoided, the high image restoration degree can be realized, and the ultra-definition projection can be realized. A three-dimensional image contained in the image data also can be accurately identified, and the three-dimensional image can be finally converted to a 3D image to be projected to a wall, a wall curtain or to realize holographic projection by virtue of the displacement adjustment of the light of a projection head in the X-axis direction, the Y-axis direction and the Z-axis direction.

Description

technical field [0001] The invention relates to the technical field of digital projection, in particular to a digital projection device capable of realizing ultra-clear playback. Background technique [0002] A projector is a device that projects images or videos onto a screen. It can be connected to a computer, VCD, DVD, BD, game console, DV, etc. through different interfaces to play the corresponding video signal or amplify the corresponding image signal. . Projectors are widely used in homes, offices, schools and entertainment venues. With the continuous reduction of the cost of projectors and the gradual improvement of projection quality, more and more film lovers like to buy and use projectors, but the current projectors are mainly divided into two categories, one is excellent image quality, brightness and The contrast is high, but the price is expensive and the volume is large. Although the other is cheaper and the volume is relatively small, but the projected pictur...

With the continuous reduction of the cost of projectors and the gradual improvement of projection quality, more and more film lovers like to buy and use projectors, but the current projectors are mainly divided into two categories, one is excellent image quality, brightness and The contrast is high, but the price is expensive and the volume is large. Although the other is cheaper and the volume is relatively small, but the projected picture quality is not good, neither of these two situations can meet the cost performance requirements of ordinary consumers for projectors.
