Abstract

The invention provides a seamless splicing method for images of projection display equipment, and the method comprises the following steps: S1, enabling the projection display equipment to comprise aplurality of surface light-emitting wafer-level LEDs, enabling an area formed by the rows and columns of each surface light-emitting wafer-level LED to be a controllable area, and setting an effectivedisplay area in each controllable area; rows and columns of each surface-emitting wafer-level LED form a small driving array, or rows and columns of a plurality of surface-emitting wafer-level LEDs are respectively connected in series to form a large driving array; and S2, respectively driving the small driving array or the large driving array in the step S1, and combining the controllable areasexcept the effective display area without display and the effective display area to form complete screen picture display.

Description

technical field [0001] The present invention relates to the technical field of projection display, and more particularly, to a method for seamless splicing of images of a projection display device. Background technique [0002] Projection display products traditionally use laser modules to emit light, and the light emitted by the light source is modulated by lighting optical systems such as condenser lenses, fluorescent wheels, color filters, condenser lenses, color wheels, and optical integrators, and then Through an independent imaging light modulator, such as DMD, the projection screen is finally realized through the lens. The light source is decomposed into pixels through the DMD components, and the brightness of each pixel is controlled by the DMD components, and then the entire surface is projected on a display screen. Due to the integrated control of the entire screen, the pixel density depends on the resolution of a DMD component, which is not easy to be high-defini...
