Description
本新型係與防疊影反射設備有關,特別是指一種使用兩個半波片內夾反射夾層,搭配P偏振影像光,可以解決入射角大約在布魯斯特角附近產生低反射與偏光太陽眼鏡看不見,以及雨滴影響畫面扭曲問題的防疊影的反射裝置。The novel is related to the anti-stacking reflection device, in particular to the use of two half-wave plate sandwich reflection interlayers, together with P-polarized image light, can solve the incident angle of about 50 degrees near the Brewster angle to produce low-reflection and polarized sunglasses I don't see, and the anti-stacking reflection device that raindrops affect the distortion of the picture.
現今汽車上使用的抬頭顯示器技術,沒有飛機上的抬頭顯示器複雜。它是一種光學系統,一般由投射器和疊像鏡二個主要裝置組成。投射器是由影像光源、投影鏡,與其他光學元件所組成。投射器的影像光源,由LCD液晶顯示器或CRT陰極射線管等裝置構成,從影像光源發出光線,然后透過投影器投射到玻璃上的疊像鏡(或特製的透明螢幕上),再由疊像鏡顯示出文字或圖像。The head-up display technology used in today's cars is not as complicated as the head-up display on the aircraft. It is an optical system and generally consists of two main devices: a projector and a mirror. The projector consists of an image source, a projection mirror, and other optical components. The image source of the projector is composed of a liquid crystal display device such as an LCD liquid crystal display or a CRT cathode ray tube, emits light from the image source, and then projects through a projector onto a stacked mirror (or a special transparent screen) on the glass, and then the image is stacked. The mirror shows text or images.
如圖1所示為習知車用擋風玻璃之顯示板,光源L投射等厚玻璃G1的兩面的投射影像路徑L1、L2不同,玻璃兩面各產生一個虛擬影像D1、D2,以致人眼E1看到兩個影像D1、D2產生疊影問題。As shown in FIG. 1 , the display panel of the conventional windshield for the vehicle is different. The projection image paths L1 and L2 of the two sides of the light source L projected on the thick glass G1 are different, and a virtual image D1 and D2 are generated on both sides of the glass, so that the human eye E1 is formed. Seeing two images D1, D2 produces a stacking problem.
如圖2所示為利用半波片搭配S偏振影像光,解決疊影問題,因為布魯斯特角的關係,P偏振影像光在擋風玻璃得到接近零反射率,但使用S偏振影像光卻會使偏光太陽眼鏡看不到。As shown in Figure 2, using a half-wave plate with S-polarized image light to solve the problem of stacking, because of the Brewster angle, P-polarized image light gets near zero reflectivity in the windshield, but using S-polarized image light will Make polarized sunglasses invisible.
如圖3所示為利用半玻片搭配P偏振影像光,可以解決布魯斯特角低反射與偏光太陽眼鏡看不見的問題,如圖4所示,因為反射層在擋風玻璃最外層,所以會受雨滴的影響,下雨時,影像扭曲。As shown in Figure 3, the use of a half-slide with P-polarized image light can solve the problem that the Brewster angle low reflection and polarized sunglasses are invisible, as shown in Figure 4, because the reflective layer is at the outermost layer of the windshield, so Under the influence of raindrops, the image is distorted when it rains.
而目前所習知應用於汽車的顯示裝置,係可參考中華民國專利I422860、159122、393582、I266075、I274683、I278651、M355841、M437281、M375629、201022734等。For the display device that is conventionally applied to automobiles, reference may be made to the Republic of China patents I422860, 159122, 393582, I266075, I274683, I278651, M355841, M437281, M375629, 201022734 and the like.
有鑑於此,本新型係提出一種防疊影的反射裝置,係可使用兩個半波片內夾反射夾層,搭配P偏振影像光,可以解決入射角大約在布魯斯特角附近產生低反射與偏光太陽眼鏡看不見,以及雨滴影響畫面扭曲問題。In view of this, the present invention proposes an anti-stacking reflection device, which can use two half-wave plate internal reflection sandwich layers, together with P-polarized image light, can solve the incident angle of about low-reflection and polarization near the Brewster angle. Sunglasses are invisible, and raindrops affect the distortion of the picture.
本新型之目的在於提供一種防疊影的反射裝置,包括一反射夾層,具有一第一表面與一第二表面,用以產生反射面;一第一半波片,設置於該反射夾層的第一表面上;以及一第二半波片,設置於該反射夾層的第二表面下。The object of the present invention is to provide an anti-stacking reflection device, comprising a reflective interlayer having a first surface and a second surface for generating a reflective surface; a first half-wave plate disposed on the reflective interlayer And a second half wave plate disposed under the second surface of the reflective interlayer.

The P-polarized image light is transmitted to the second glass, and the P-polarized image light is converted by the second half-wave plate and a second surface of the reflective interlayer. Forming an S-polarized image light, wherein the second surface reflection portion of the reflective interlayer is an S1 polarization image light, and the S1 polarization image light passes through the second half wave plate and the second glass interface , the S1 polarized image light is converted into P1 polarized image light, the P1 polarized image light is transmitted through the second glass, and is emitted toward the human eye, and the S-polarized image light is reflected by a first surface of the reflective interlayer as an S2 polarized image light, the S2 When the polarized image light passes through the second half wave plate and the second glass, the S2 polarized image light is converted into a P2 polarized image light, and the P2 polarized image light penetrates the second glass and is emitted toward the human eye.
藉此,因反射夾層很薄(約10~950nm),所以P1偏振影像光與P2偏振影像光於人眼看起來是重疊的,第一半波片與夾層折射率接近,所以交界處反射率就低,S偏振影像光穿透反射夾層的部份為S3偏振影像光,而S3偏振影像光穿透第一半波片與夾層交界處時,S3偏振影像光轉換成P3偏振影像光,因為布魯斯特角的關係,P3偏振影像光在夾層與第一玻璃得到接近零反射率,P3偏振影像光由第一半波片射出夾層與第一玻璃,可以解決入射角大約在布魯斯特角附近產生低反射與偏光太陽眼鏡看不見,以及雨滴影響畫面扭曲問題。Therefore, since the reflective interlayer is very thin (about 10 to 950 nm), the P1 polarized image light and the P2 polarized image light appear to overlap in the human eye, and the first half wave plate and the interlayer refractive index are close, so the reflectance at the junction is Low, the portion of the S-polarized image that penetrates the reflective interlayer is S3 polarized image light, and when the S3 polarized image light penetrates the junction of the first half-wave plate and the interlayer, the S3 polarized image light is converted into P3 polarized image light because Bruce The relationship between the special angles, the P3 polarized image light is close to zero reflectivity in the interlayer and the first glass, and the P3 polarized image light is emitted from the first half wave plate by the interlayer and the first glass, which can solve the incident angle which is low near the Brewster angle.
