Color changing mirror device with touch unit

The present invention provides a rear view mirror device, and more particularly to a color change rear view mirror device having a touch unit.

On the land with limited land area, with the popularization of land vehicles, the density of vehicles has gradually increased, which has led to the deterioration of the driving environment and the frequent occurrence of traffic accidents.

I know that when driving, I often encounter the situation that the rear car is hitting the high beam under the weak driving environment at night or facing the strong sunlight during the day. These situations easily lead to the driver's sight being affected by the rear view of the car. The glare generated by the rearview mirror is prone to traffic accidents. Therefore, many manufacturers have developed many anti-glare rearview mirrors. In general, there are many techniques for making the mirrors anti-glare function. Herein, it is most common to add a color-changing material to the structure of the rearview mirror to change the color of the emitted light to achieve anti-glare.

Conventionally, the color-changing material can be roughly classified into an electrochromism (EC) material, a thermochromism material, and a photochromism material according to the driving manner thereof. Among them, electrochromic materials are the most widely used. The principle of electrochromism is to change the color or transmittance of a material by changing the applied voltage of the material to cause a redox reaction. Therefore, in general, an electrochromic element is formed by sandwiching a specific electrochromic material between two sheets of glass and changing the discoloration of the electrochromic material by energization of the glass.

In addition, it is conventional to use the rear view mirror only for the driver to observe the movement of the rear vehicle without such a function. Therefore, in recent years, in order to avoid the occurrence of a traffic accident, the driver may be plagued by imprisonment or civil compensation because his case or responsibility cannot be clarified, and more than a vehicle photographic device is installed in the vehicle. In general, vehicle photographic devices are often installed in vehicles by means of fixed brackets. However, this additional photographic camera device requires an additional space for the original vehicle and is destroyed. The original design of the original vehicle.

Hereinafter, the outline process sequence of the color changing mirror 120 of one embodiment of the present invention is described.

First, the first substrate 121 is used as a base. The first substrate 121 has a first surface 121a and a second surface 121b with respect to the first surface 121a.

(CVD), etc. In addition, the first conductive layer 122 may be a transparent conductive film, and the material thereof may be indium tin oxide (ITO), fluorine tin oxide (FTO), aluminum zinc oxide (AZO), gallium zinc oxide (GZO), or the like.

The touch panel 125 is used as another substrate. The touch panel 125 has a top surface 125a and a back surface 125b opposite to the top surface 125a. Here, the top surface 125a refers to the touch panel 125 for the user to touch the surface. In addition, the touch panel 125 can be a capacitive touch panel.

Next, the second conductive layer 124 is disposed on the back surface 125b of the touch panel 125. The second conductive layer 124 is disposed on the second substrate 1251 of the touch panel 125 . In other words, the sensing electrode layer 1252 and the second conductive layer 124 may be respectively disposed on opposite sides of the second substrate 1251.

In addition, the second conductive layer 124 may be a transparent conductive film, and the material thereof may be indium tin oxide (ITO), fluorine tin oxide (FTO), aluminum zinc oxide (AZO), gallium zinc oxide (GZO), or the like.

After the conductive layers of the two substrates (ie, the first substrate 121 and the touch panel 125) are all disposed, the touch panel 125 can be bonded to the first substrate 121.

In this embodiment, after the adhesive is applied to the periphery of the first conductive layer 122 through the dispenser, the touch panel 125 is disposed toward the first conductive layer 122 with the second conductive layer 124 on the back surface 125b thereof. And attached to the first conductive layer 122. Wherein, the adhesive may be an epoxy resin mixed with a glass ball. In one embodiment, the glass spheres may have a diameter of 120 microns.

It can be seen from the above that although the color changing mirror 120 of the embodiment of the present invention integrates the touch panel 125, the integration is achieved by using only the two substrates (the first substrate 121 and the second substrate 1251). The overall structure of the color changing mirror 120 of the embodiment can be thinner than conventional.

In this embodiment, as shown in FIG. 4 or FIG. 5, the first conductive layer 122 of the color changing mirror 120 can be electrically connected to a first potential V1, and the second conductive layer of the rear view mirror 120 is discolored. The electrically conductive layer 123 is electrically connected to the second potential V2, so that the electrochromic layer 123 between the first conductive layer 122 and the second conductive layer 124 can be based on a potential difference between the first potential V1 and the second potential V2. Discoloration, when the potential difference between the first potential V1 and the second potential V2 is less than the set value, the electrochromic layer 123 of the discoloration mirror 120 is gradually decolored, and returns to the general rear view mirror.

Please refer to FIG. 1 and FIG. 2 simultaneously. The first photodetector 131 can be located on the first side 110a of the housing 110 to detect the amount of light incident at the first side 110a of the housing 110, and the second light. The detector 132 is oppositely located on the second side 110b of the housing 110 to detect the amount of light incident at the second side 110b of the housing 110. The detecting the amount of light incident on the first side 110a of the housing 110 means detecting the amount of light incident on the color changing mirror 120 incident on the front side of the color changing mirror device 100, and detecting the housing 110 The amount of light incident at the second side 110b refers to detecting the amount of light incident incident on the rear surface of the color changing mirror device 100.

For example, when the color changing mirror device 100 of the present embodiment is installed in a vehicle body, the first photodetector 131 can be used to detect the incident from the rear of the vehicle body to the front side of the color changing mirror device 100. The amount of light incident on the mirror 120 is changed, and a voltage or current is generated according to the detected amount of light incident; and the second photodetector 132 can be used to detect the incident from the front of the vehicle body to the color changing mirror. The amount of light incident on the rear surface of the device 100, and the voltage or current is generated according to the detected amount of light incident, and the voltage or current of the two is passed to the judging circuit to determine the amount of light difference on both sides. When the amount of light incident behind the body and the amount of light incident from the front of the vehicle body are larger, the voltage difference between the first potential V1 and the second potential V2 is larger, and finally reaches a maximum value.

In some embodiments, the determining circuit of the light incident amount of the first photodetector 131 and the second photodetector 132 may use a Schmitt Trigger to reduce the first photodetector 131 or The second photodetector 132 is misjudged by the discoloration of the electrochromic layer 123, and the electrochromic layer 123 can be brought to a state of maintaining a completely discolored state for a long time.

Therefore, when the voltage difference between the first potential V1 and the second potential V2 exceeds a set value, the electrochromic layer 123 of the color changing mirror 120 starts to be colored to attenuate the light incident on the color changing mirror 120. The intensity of the reflection; when the voltage difference between the first potential V1 and the second potential V2 gradually decreases and is less than the set value, the electrochromic layer 123 of the color changing mirror 120 is gradually decolored, and the response is normal. rearview mirror.

In this embodiment, the first photodetector 131 can be located behind the discoloration mirror 120 and hidden in the groove portion 111 of the housing 110, and the discoloration mirror 120 can be opposite to the first photodetector. A light penetrating area A1 is disposed at the position of the 131 to enable the first photodetector 131 to detect light incident on the color changing mirror 120 via the light penetrating area A1. Therefore, opposite holes can be formed in the light absorbing film layer 126 of the color changing mirror 120 to form the aforementioned light penetrating area A1. Here, as shown in FIG. 3, the light penetrating area A1 may be disposed at the center of the color changing mirror 120.

The second photodetector 132 can be inserted into the through hole of the bottom surface of the groove portion 111 from the inner side of the groove portion 111 of the housing 110 to detect the light at the second side 110b of the housing 110 from the through hole. Incident amount.

In some embodiments, the first photodetector 131 and the second photodetector 132 can be implemented as a photodiode.

The driving information may include the tire pressure value transmitted by the tire pressure detector, indoor and outdoor temperature, oil temperature or other vehicle information that must be displayed on the screen. Therefore, in an embodiment, the color changing mirror 120 of the color changing mirror device 100 further includes a display area A2.

The display area A2 includes a first opening, wherein the first opening is formed in the light absorbing film layer 126 of the color changing mirror 120, so that the color light corresponding to the display 140 disposed behind the display area A2 of the color changing mirror 120 can be worn. It reveals and presents the desired image for the user to watch.

In this embodiment, the display area A2 is substantially rectangular, and can be disposed on the left side of the color changing mirror 120, so as to be close to the driver's position and convenient for the driver to view, but the present invention is not limited thereto, in another In the embodiment, the display area A2 may also be disposed on the right side of the color changing mirror 120.
