Abstract

"DISPOSIçãO CONSTRUTIVA INTRODUZIDA EM APARELHO DE PROJEçãO DE IMAGENS A LASER". Representada por uma solução inovadora e revolucionária em termos de projeção de imagens, representando grandes vantagens em relação aos aparelhos projetores de imagens conhecidos do estado da técnica, tais como aparelhos de televisão, HDTV, monitor de computador, tela de cinema digital, letreiro digital em lojas, outdoor, HMD, HDHMD ente outros, pois tal inovação viabiliza a miniaturização de todos ao componentes necessários à projeção de imagem, possibilitando assim ganhos explícitos em termos de portabilidade do aparelho, com peso extremamente reduzido, representando ainda uma significativa redução de custo de fabricação e de utilização. O aparelho ora reivindicado é baseado em um aparelho que ao receber um sinal de vídeo (1) demodula-o transformando-o em variações na potência de emissão de feixes de luz laser (RGB - vermelho, verde e azul) por um processo de modulação de intensidade, o qual segue a um aparelho rasterizador xy (5), podendo esta modulação ser feita através de um aparelho modulador direto (4.1) ou posterior (4.2). O elemento rasterizador xy (5) varre o feixe de luz laser compondo uma imagem, sendo que esta é projetada em um anteparo (7) e continuamente corrigida e refinada através de um sensores de excursão e intensidade(6)."CONSTRUCTIVE PROVISION INTRODUCED IN LASER IMAGE PROJECTOR". Represented by an innovative and revolutionary image projection solution, it has great advantages over state-of-the-art image projectors such as television sets, HDTVs, computer monitors, digital movie screens, digital signage in stores, billboards, HMD, HDHMD and others, as such innovation enables the miniaturization of all the components required for image projection, thus enabling explicit gains in terms of the portability of the device, with extremely low weight, representing a significant reduction in the cost of manufacture and use. The apparatus herein claimed is based on an apparatus which upon receiving a video signal (1) demodulates it into variations in the laser beam emission power (RGB - red, green and blue) by a modulation process. intensity, which follows an xy rasterizer apparatus (5), which can be modulated by a direct modulator apparatus (4.1) or later (4.2). The xy raster element (5) scans the laser light beam composing an image, which is projected onto a screen (7) and continuously corrected and refined through an excursion and intensity sensor (6).
