The invention concerns a display (1) comprising: a housing (10), inside the housing, a light guide (50) comprising an inlet face and an opposing outlet face, connected by a lateral wall, collecting, at its inlet face, light radiation outside the housing, and guiding the radiation to its outlet face, behind the outlet face, a light sensor (30) delivering a signal representative of a light intensity that it receives, and, an image generation unit (20) generating an image. According to the invention, the lateral wall of the light guide is shaped such that stray light radiation entering the light guide from an angular zone extending beyond a zone of interest (Z1) exits the light guide without reaching its outlet face.
本发明涉及一种显示器(1),其包括:外壳(10),在外壳内部的光导(50),其包括彼此相对并且通过侧壁彼此连接的入光面和出光面,光导经由其入光面收集来自外壳外部的光辐射并将所述光辐射引导至其出光面,在所述出光面后面的光传感器(30),其传送表示其接收的光强的信号,以及生成图像的图像生成单元(20)。根据本发明,光导的侧壁被成形为使得从延伸超过感兴趣区域(Z1)的角度区域进入光导的杂散光辐射离开所述光导而不到达其出光面。
