视频观看设备
摘要：
本发明提供一种视频观看设备。以往的自发光显示器(40)在从自发光面板(47)发出的显示光(51)(视频)通过偏振膜(43)时，光量的大约50％被偏振膜(43)吸收，因此显示画面较暗。且以往的自发光显示器(40)的防反射功能不充分，因此为了观看高品质的视频需要使房间变暗。本发明的视频观看设备(10)具备自发光显示器(30)和圆偏振光光源(11)，自发光显示器(30)按顺序具有：(a)第一波片(13)，具有对圆偏振光与直线偏振光进行相互转换的功能；(b)偏振膜(15)；(c)直线偏振光分离膜(20)；(d)第二波片(18)，具有对圆偏振光与直线偏振光进行相互转换的功能；(e)自发光面板(16)。
摘要（英）：

The invention provides a video appreciation device. When the display lights (51) (video) sent from a self-luminous panel (47) by a traditional self-luminous display (40) passes through a polarization film (43), about 50% of the lights are absorbed by the polarization film (43) so the display frame is dark. The traditional self-luminous display (40) has an insufficient anti-reflection function so the room required being dark if user wants to appreciate high-quality video. The video appreciation device (10) of the invention is provided with a self-luminous display (30) and a circularly-polarized light source (11), wherein the self-luminous display (30) comprises in order: (a) a first wavelength plate (13) having functions to convert circularly-polarized light into linearly-polarized light and vice versa, (b) a polarizing film (15), (c) a linearly-polarized separation film (20), (d) a second wavelength plate (18) having functions to convert circularly-polarized light into linearly-polarized light and vice versa, and (e) a self-luminous panel (16).
