Description
一种抗反光干扰的后视镜显示器 技术领域 Rear view mirror display with anti-reflective interference
本实用新型涉及一种倒车后视装置， 更具体地说， 涉及一种抗反 光干扰的后视镜显示器。 背景技术 The utility model relates to a rear view rear view device, and more particularly to a rear view mirror display which is resistant to light interference. Background technique
在倒车时， 驾驶员希望通过其眼前的后视镜显示器， 看到汽车后 方的倒车影像， 并且希望显示在屏幕上的倒车影像是高亮和清晰的。 由于传统的后视镜显示器里的玻璃容易受到外面环境光线或车灯的 强烈照射而产生干扰，从而影响后视镜显示器里倒车影像被人眼清晰 地看到。传统后视镜显示器的显示区域， 在倒车时有 2个图像， 即后 视镜显示器倒车图像和镜面反射车后方的反射图像；当外界光线很强 的时候， 镜面反射车后方的反射图像， 亮度会非常高，可能高达 2000 cd/m2到 5000cd/m2 , 而显示器屏幕的亮度很难与之抗衡，所以造成人 眼睛无法看清楚后视镜显示器倒车图像。 这样就会让驾驶员出现误 判， 从而导致车祸的发生。 When reversing, the driver wants to see the reversing image behind the car through the front view mirror display in front of the car, and the reversing image that is desired to be displayed on the screen is highlighted and clear. Since the glass in the conventional rear view mirror display is easily disturbed by the external ambient light or the strong illumination of the lamp, the reverse image in the rear view mirror display is clearly seen by the human eye. The display area of the conventional rear view mirror display has two images when reversing, that is, the rear view mirror display reversing image and the reflection image behind the specular reflection car; when the external light is strong, the specular reflection of the rear of the car reflects the brightness, brightness It will be very high, probably as high as 2000 cd/m 2 to 5000 cd/m 2 , and the brightness of the display screen is difficult to compete with, so that the eyes cannot see the rear view mirror reversing image. This will cause the driver to misjudge, resulting in a car accident.
一般来说，后视镜显示器中整个玻璃分为屏幕显示区和非屏幕显 示区，传统的后视镜显示器的玻璃上有镀膜层，镀膜层分为两个区域， 一个是屏幕显示区， 一个是非屏幕显示区； 两个区域的反射率是基本 一样的， 因为非屏幕区域背面被贴上黑胶布或丝印黑色遮光层， 所以 非屏幕区域是不透光的； 而屏幕显示区域则有一定的透光率， 使得显
示器图像可以穿透镜面被人眼看到。 这种方法中， 屏幕显示区和非 屏幕显示区的反射率， 是一起升高或一起降低的。而倒车的时候， 两 个区域的反射率都处于很高的状态，所以造成屏幕显示区既有后视镜 显示器倒车图像， 也有镜面反射车后方的反射图像， 产生严重的视觉 干扰， 影响人看清后视镜显示器倒车图像。 Generally speaking, the whole glass in the rear view mirror display is divided into a screen display area and a non-screen display area. The traditional rear view mirror display has a coating layer on the glass, and the coating layer is divided into two areas, one is a screen display area, one The non-screen display area; the reflectivity of the two areas is basically the same, because the back of the non-screen area is affixed with black tape or silk screen black shading layer, so the non-screen area is opaque; and the screen display area has a certain Light transmittance The image of the indicator can be seen by the human eye through the lens surface. In this method, the reflectances of the screen display area and the non-screen display area are raised together or lowered together. When reversing, the reflectivity of the two areas is in a very high state, so the screen display area has both the rear view mirror display reversing image and the specular reflection car rear reflection image, which causes serious visual interference, affecting people to see. Rear view mirror display reversing image.
如图 1所示,传统的后视镜显示器是在后视镜玻璃 2上直接贴显示 屏 3， 其中的后视镜玻璃， 可以是 EC电子防眩目的双层玻璃中间夹 一层化学材料的玻璃， 可以是手动防眩目楔形玻璃； 也可以是普通半 透膜平面玻璃。由于后视镜玻璃的屏幕显示区和非屏幕显示区都镀有 一层膜， 从而造成屏幕显示区和非屏幕显示区具有相接近的反射率， 如图 2所示,当在夜里， 没有外面环境光或车灯照射过来时， 后视镜 显示屏 3 中显示的倒车图像是清晰的。 当在白天车外面环境光很强 时， 由于反光干扰， 后视镜显示屏 3中显示的倒车图像被外界强光在 镜面上形成的镜面反射车后方的反射图像所干扰，人眼无法看清楚图 像， 如图 3所示， 图像中的人是后视镜显示屏 3中显示的倒车图像， 图像中的汽车是镜面反射车后方的反射图像。 在没有外界强光照射 时， 屏幕中的人是清晰的， 当外界强光照射时， 由于外界强光的亮度 超过屏幕显示的亮度， 屏幕中的人就变得模糊， 反而是镜面反射后方 的反射图像汽车就变得高亮清晰，驾驶员就会因为外界强光所造成的 干扰而会忽略车后方的人， 从而导致车祸发生。
本实用新型所要解决的技术问题是提供一种结构紧凑， 经济实 惠， 实用性强的抗反光干扰的后视镜显示器。 As shown in Fig. 1, the conventional rearview mirror display is directly attached to the display screen 3 on the mirror glass 2, wherein the rearview mirror glass can be a layer of chemical material sandwiched between the double-glazed glass of the EC electronic anti-glare. The glass can be a manual anti-glare wedge glass; it can also be a plain semi-transparent flat glass. Since the screen display area and the non-screen display area of the mirror glass are plated with a film, the screen display area and the non-screen display area have similar reflectances, as shown in FIG. 2, when there is no outside environment at night. When the light or the headlights illuminate, the reverse image displayed in the rear view mirror display 3 is clear. When the ambient light outside the daytime vehicle is very strong, the reverse image displayed on the rear view mirror display 3 is disturbed by the reflected image behind the specular reflection vehicle formed by the external strong light on the mirror surface due to the reflection interference, and the human eye cannot see clearly. Image, as shown in Fig. 3, the person in the image is the reverse image displayed in the rear view mirror display 3, and the car in the image is a reflection image behind the specular reflection vehicle. When there is no external strong light, the person on the screen is clear. When the external strong light is shining, because the brightness of the external strong light exceeds the brightness of the screen display, the person in the screen becomes blurred, but the mirror reflection is behind. The reflected image of the car becomes bright and clear, and the driver will ignore the person behind the car because of the interference caused by the external glare, resulting in a car accident. The technical problem to be solved by the utility model is to provide a rear view mirror display with anti-reflective interference structure which is compact, economical and practical.
为了解决上述技术问题， 本实用新型采用了以下技术方案： 一种抗反光干扰的后视镜显示器，包括后视镜本体、后视镜玻璃、 显示屏、 PCB板，所述后视镜玻璃的后方显示屏的上方设有附加玻璃， 所述后视镜玻璃与附加玻璃之间形成一个夹层空腔，所述夹层空腔的 四周设有封口胶，所述后视镜玻璃和附加玻璃与夹层空腔连接的玻璃 层面分别设有导电层，所述后视镜玻璃和附加玻璃的边缘分别设有电 极，所述附加玻璃的电极与后视镜玻璃的电极通过电线与 PCB板相连 接， 所述夹层空腔内置有化学材料。 In order to solve the above technical problem, the utility model adopts the following technical solutions: A rear view mirror display resistant to light reflection, comprising a rear view mirror body, a rear view mirror glass, a display screen, a PCB board, and the rear view mirror glass An additional glass is disposed above the rear display screen, and a sandwich cavity is formed between the mirror glass and the additional glass, and a sealing glue is disposed around the interlayer cavity, the mirror glass and the additional glass and the interlayer The glass layers connected to the cavity are respectively provided with a conductive layer, and the edges of the mirror glass and the additional glass are respectively provided with electrodes, and the electrodes of the additional glass and the electrodes of the mirror glass are connected to the PCB through the wires. The interlayer cavity is filled with a chemical material.
优选地， 上述夹层空腔内也可设置光学膜片。 Preferably, an optical film may also be disposed in the interlayer cavity.
优选地， 可在所述夹层空腔两端的封口胶上分别设置软管， 软管 的一端连接电磁阔， 所述电磁阔与 PCB板电连接， 在所述夹层空腔内 设置反光液体。 Preferably, a hose is respectively disposed on the sealing glue at both ends of the interlayer cavity, and one end of the hose is connected to the electromagnetic width, and the electromagnetic width is electrically connected to the PCB board, and a reflective liquid is disposed in the interlayer cavity.
所述后视镜玻璃分为屏幕显示区和非屏幕显示区，所述非屏幕显 示区设有镀膜层。 The mirror glass is divided into a screen display area and a non-screen display area, and the non-screen display area is provided with a coating layer.
本实用新型由于采用了上述结构， 后视镜玻璃中屏幕显示区为非 镀膜层， 为了降低外面环境光或车灯等强光的照射干扰， 在非镀膜层 屏幕显示区上封装一片附加玻璃，且在附加玻璃与后视镜玻非镀膜层 之间加化学材料， 通电时， 由于化学材料的分子的扩散与重新排列， 后视镜屏幕显示区透光率会提高， 而反射率会大大降低， 不通电时，
性地采用改变后视镜显示器显示区域反射率和透光率的方法，当倒车 的时候， 后视镜显示区反射率降低， 透光率增加， 这样镜面反射车后 方的反射图像亮度大大降低，而后视镜显示屏发出的光线穿透后视镜 的亮度大大提高。被人眼看到的后视镜显示屏倒车图像亮度变亮， 使 得显示对比度大大提高， 图像变得很容易被看清楚。而平时驾驶的时 候， 因为显示器是不工作的， 所以通过控制系统， 将屏幕显示区的反 射率跟非屏幕显示区变得几乎一样，后视镜玻璃的两个区域也就组合 成了一个完整的镜面，从而让驾驶员通过整个后视镜清晰地看到车后 方的倒车图像。 在结合附图阅读本实用新型的实施方式的详细描述后， 本实用新 型的特点和优点将变得更加清楚。 附图说明 图 1是传统后视镜显示器玻璃与显示屏结构示意图； Since the utility model adopts the above structure, the screen display area of the rearview mirror glass is a non-coating layer, and in order to reduce the illumination interference of external ambient light or a strong light such as a lamp, an additional glass is packaged on the uncoated layer screen display area. And chemical material is added between the additional glass and the non-coated layer of the mirror glass. When the power is applied, due to the diffusion and rearrangement of the molecules of the chemical material, the transmittance of the display area of the rearview mirror will increase, and the reflectivity will be greatly reduced. , when not powered, The method of changing the reflectance and the transmittance of the area of the rear view mirror display is adopted. When the vehicle is reversed, the reflectance of the rear view mirror display area is lowered, and the light transmittance is increased, so that the brightness of the reflected image behind the specular reflection vehicle is greatly reduced. The brightness of the rear view mirror is greatly increased by the light from the rear view mirror display. The brightness of the reversing image of the rear view mirror display that is seen by the human eye is brightened, so that the display contrast is greatly improved, and the image becomes easy to be seen clearly. When driving normally, because the display is not working, the control system makes the reflectivity of the screen display area almost the same as the non-screen display area, and the two areas of the mirror glass are combined into one complete. The mirror surface allows the driver to clearly see the reverse image behind the car through the entire rearview mirror. The features and advantages of the present invention will become more apparent from the detailed description of the embodiments.

实施例 1： Example 1:

A chemical material 61 is disposed within the interlayer cavity 6.
如图 7所示， 图中， 左边为后视镜玻璃 2的正面 A, 右边为后视 镜玻璃 2的背面 B, 正面 A是指人眼看到后视镜的正前面， 背面 B是 指正前面的背面， 后视镜玻璃 2整个区域分为非屏幕显示区 21和屏 幕显示区 22， 非屏幕显示区 22上设有镀膜层。 在后视镜玻璃 2背面
的半透光反射膜层，在屏幕显示区 22为超高透光和低反射率的膜层， 而在非屏幕显示区 21则为高反射率超低透光率的膜层。 非屏幕显示 区 21和屏幕显示区 22的分界处，反射率和透光率的变化有一个渐变 的过程， 来淡化两个区域的分界线。 As shown in Fig. 7, in the figure, the left side is the front side A of the rear view mirror glass 2, and the right side is the back side B of the rear view mirror glass 2, the front side A refers to the front side of the rear view mirror, and the front side B refers to the front side. On the back side, the rear view mirror glass 2 is divided into a non-screen display area 21 and a screen display area 22, and a non-screen display area 22 is provided with a coating layer. On the back of the rearview mirror glass 2 The semi-transmissive reflective film layer is a film layer of ultra-high light transmittance and low reflectivity in the screen display area 22, and a film layer with high reflectivity and ultra-low transmittance in the non-screen display area 21. At the boundary between the non-screen display area 21 and the screen display area 22, there is a gradual change in reflectance and transmittance to dilute the boundary between the two areas.
本实用新型通过在后视镜玻璃的屏幕显示区上叠加一片附加玻 璃 5， 其中的后视镜玻璃 2， 可以是 EC电子防眩目双层玻璃， 可以是 手动防眩目的楔形玻璃； 也可以是普通半透膜平面玻璃。 除了叠加 一片附加玻璃 5外，还在后视镜玻璃 2与附加玻璃 5之间添加导电化 学材料 61， 为了不让化学材料 61外溢， 在附加玻璃 5与后视镜玻璃 2之间涂装密封性能强的封口胶 7， 附加玻璃 5的电极 9与后视镜玻 璃 2的电极 9通过电线 10与 PCB板 4相连接。 PCB板 4上的光敏传 感器受到强光照射后，附加玻璃 5的导电层 8与后视镜玻璃 2的导电 层 8上的正负电压会发生变化，受电压变化控制的附加玻璃 5与后视 镜玻璃 2内的化学材料 61的分子导电后，排列方式马上会发生变化， 从而控制显示区的透光率与反射率， 最终达到抗反光干扰的效果。 The utility model superimposes an additional glass 5 on the screen display area of the rear view mirror glass, wherein the rear view mirror glass 2 can be an EC electronic anti-glare double-layer glass, which can be a manual anti-glare purpose wedge glass; It is an ordinary semi-transparent film flat glass. In addition to superimposing a piece of additional glass 5, a conductive chemical material 61 is added between the mirror glass 2 and the additional glass 5, and a seal is applied between the additional glass 5 and the mirror glass 2 in order to prevent the chemical material 61 from overflowing. The high performance sealing glue 7, the electrode 9 of the additional glass 5 and the electrode 9 of the mirror glass 2 are connected to the PCB board 4 via the electric wire 10. After the photosensitive sensor on the PCB 4 is exposed to strong light, the positive and negative voltages on the conductive layer 8 of the additional glass 5 and the conductive layer 8 of the mirror glass 2 are changed, and the additional glass 5 and the rear view controlled by the voltage change are changed. After the molecules of the chemical material 61 in the mirror glass 2 are electrically conductive, the arrangement pattern changes immediately, thereby controlling the light transmittance and the reflectance of the display region, and finally achieving the anti-reflective interference effect.
如图 8所示， 汽车向前行驶显示屏不亮时， 屏幕显示区的化学材 料 61通过附加玻璃 5上的电极 9和后视镜玻璃 2上的电极 9， 受后 视镜电路的控制， 相关的化学元素高度集中到后视镜玻璃导电层 8 上， 在后视镜玻璃导电层 8上形成了一个高反射率、低透光率的高反 射率反射层， 这个后视镜玻璃导电层 8的高反射层， 和非屏幕显示区 21 的高反射层， 这两个反射层拼接成了一个镜面， 而且因为这个反
个反射层区域之间的界限， 从而形成了一个完美的镜面被驾驶者看 到。 为了更加淡化两个反射层的界限， 后视镜玻璃上的屏幕显示区As shown in FIG. 8, when the vehicle is driving forward, the display material is not illuminated, and the chemical material 61 of the screen display area is controlled by the mirror circuit by the electrode 9 on the additional glass 5 and the electrode 9 on the mirror glass 2. The relevant chemical elements are highly concentrated on the mirror glass conductive layer 8, and a high reflectivity, low transmittance, high reflectivity reflective layer is formed on the mirror glass conductive layer 8, which is a mirror glass conductive layer. a highly reflective layer of 8, and a highly reflective layer of the non-screen display area 21, the two reflective layers are spliced into a mirror, and because of this inverse The boundary between the areas of the reflective layer, thus forming a perfect mirror to be seen by the driver. In order to further dilute the boundaries of the two reflective layers, the screen display area on the mirror glass
22和非屏幕显示区 21之间的反射镀膜层区域， 做一个渐变的处理， 即屏幕显示区 22的高透光低反射， 到了靠近非屏幕显示区的地方， 慢慢降低镀膜层透光率增加反射率， 最终完全进入非屏幕显示区之 后， 完全变成高反射低透光镀膜层。 The reflective coating layer area between the 22 and the non-screen display area 21 is subjected to a gradual processing, that is, the high light transmission and low reflection of the screen display area 22, and the place near the non-screen display area is slowly lowered to reduce the transmittance of the coating layer. Increasing the reflectivity, and finally entering the non-screen display area, completely becomes a highly reflective low-transparent coating layer.
如图 9所示， 当倒车或屏幕需要显示时， 屏幕显示区 22的化学 材料受后视镜电路的控制，相关的化学元素处于高透光率低反射率状 态， 因为屏幕显示区 22的低反射率状态， 所以在这区域对人眼几乎 没有任何干扰； 因为屏幕显示区 22是高透光率状态， 所以显示器发 出的光线高效率地通过后视镜， 被人眼睛看到， 而非屏幕显示区 21 的高反射率反射层， 则高效地反射着车后方的影像， 屏幕显示区和 非屏幕显示区一起， 给驾驶者真实地呈现了车后方的信息。 As shown in FIG. 9, when the reverse or screen needs to be displayed, the chemical material of the screen display area 22 is controlled by the mirror circuit, and the relevant chemical elements are in a state of high transmittance and low reflectivity because of the low screen display area 22. Reflectivity state, so there is almost no interference to the human eye in this area; because the screen display area 22 is in a high light transmittance state, the light emitted by the display passes through the rear view mirror efficiently, is seen by the human eye, not the screen. The high-reflectivity reflective layer of the display area 21 reflects the image behind the vehicle efficiently, and the screen display area and the non-screen display area together give the driver a realistic representation of the information behind the vehicle.
如图 10所示， 在没有外界强光照射时， 屏幕中的人是清晰的， 当外界强光照射时， 后视镜显示屏 3中的显示区玻璃和后视镜玻璃 2 的电极 9金属条导通， 电压发生变化， 化学材料的分子重新排列， 使 得后视镜显示区 22处于低反射高透光状态， 即使外界强光的亮度超 过屏幕显示的亮度， 屏幕中的人也会变得清晰， 由于此时是低反射， 反而是镜面反射后方的反射图像汽车就变得模糊不清，驾驶员就不会 有视觉干扰， 并且能清晰地看到后视镜显示器倒车图像， 从而辟免车 祸发生。
参阅图 12， 在后视镜玻璃显示区的后面， 粘贴一片附加玻璃 5， 且在附加玻璃 5与后视镜玻璃 2的四周涂上封口胶 7， 并在两边的封 口胶 7上打孔， 封口胶 7的两个孔装上特制软管 11， 软管 11与电磁 阔 12相连。 电磁阔 12上电线与后视镜电路相连， 通过后视镜电路， 对后视镜玻璃 2与附加玻璃之 5间的反光液体 13进行控制， 当反光 液体 13全部均匀地吸附在后视镜屏幕显示区 22时，后视镜玻璃 2则 透光率低， 反光率高， 当反光液体 13通过电磁阔 12被软管 11吸离 后视镜屏幕显示区 22时， 后视镜玻璃 2则透光率高， 反光率低。 As shown in Fig. 10, the person in the screen is clear when there is no external strong light illumination, and the display area glass in the rear view mirror display 3 and the electrode 9 of the rear view mirror glass 2 are metal when the external strong light is irradiated. The strip is turned on, the voltage changes, and the molecules of the chemical material are rearranged, so that the rear view mirror display area 22 is in a low reflection and high light transmission state, and even if the brightness of the external strong light exceeds the brightness of the screen display, the person in the screen becomes Clear, because it is low reflection at this time, but the reflection image behind the specular reflection becomes blurred, the driver will not have visual interference, and the rear view mirror display reversing image can be clearly seen. A car accident happened. Referring to FIG. 12, behind the rear view mirror glass display area, a piece of additional glass 5 is pasted, and a sealing glue 7 is applied around the additional glass 5 and the rear view mirror glass 2, and the sealing glue 7 on both sides is punched. The two holes of the sealant 7 are fitted with a special hose 11 which is connected to the electromagnetic width 12. The electromagnetic wide 12 wire is connected to the rear view mirror circuit, and the reflective liquid 13 between the rear view mirror glass 2 and the additional glass is controlled by the rear view mirror circuit, and the reflective liquid 13 is uniformly adsorbed on the rear view mirror screen. When the display area 22 is displayed, the rear view mirror glass 2 has a low light transmittance and a high light reflectance. When the reflective liquid 13 is sucked away from the rear view mirror screen display area 22 by the electromagnetic opening 12, the rear view mirror glass 2 is transparent. High light rate and low light reflectivity.
