Benefits of technology

The technical effect that this new technology allows users to better control how well their projected images look on them compared to previous methods. This means they will have more consistently high-quality displays even when used under varying conditions such as lighting levels or view angles.

Problems solved by technology

This patented technical problem addressed in this patents relates to improving the quality of images displayed on large displays due to higher resolution requirements compared to smaller screens like cathode ray tubes or LiquidCrystals (LCM)). Current methods require constant changing the entire amount of energy supplied to each pixel during operation, leading to shorter lifetimes and increased maintenance expenses. To address these issues, there proposed a solution called Dynamic Adjustments Projection System(ADSP)) was introduced where multiple pixels can individually control how they emit lights independently without interferring any others.

Embodiment Construction

[0022] see figure 2 , figure 2 A schematic diagram of a projection display device 3 according to a specific embodiment of the present invention is shown. The projection display device 3 can be widely used in various occasions such as home, entertainment, or business to display specific output images (such as TV images, movie playback, or work briefings, etc.). like figure 2 As shown, in this embodiment, the projection display device 3 may include components such as a light source 30, a color wheel 32, a driving circuit 34, a processing module 36, and a color wheel control module 38 for controlling the color wheel 32, but the present invention does not This is the limit. In practical applications, in order to actually complete the projection and imaging of light, the projection display device 3 may further include other necessary or optional components such as a light guide, a lens group for splitting and combining light, a DMD, and an imaging lens. It is well known to many

Abstract

The invention relates to a method for the dynamic regulation of projection and a projection display device. The technical problem to be solved by the invention is to provide the method for the dynamic regulation of projection. The method for the dynamic regulation of projection is suitable for a projection display device which is used for displaying output images and comprises a light source, wherein the light source is driven by pulse periodic signals. The method for the dynamic regulation of projection comprises the following steps of: (a) judging brightness parameters of the output images; (b) regulating the pulse periodic signals according to the brightness parameters; and (c) driving the light source by using the pulse periodic signals.
