Description
Technical Field

Background
Generally, the field of view when driving a car is limited. The driver can only determine the coming vehicle around and behind by the left and right side rearview mirrors and the inside rearview mirror in the road running process, so that the sight of the driver has dead angles, namely blind areas. If the locomotive or the automobile enters the blind areas behind the two sides, the driver can not perceive the existence of the other side through the left and right side rearview mirrors and the inside rearview mirror. Even if the blind area warning system is additionally arranged, the device only flashes the lights or gives a sound warning beside the rearview mirrors on the left side and the right side, and a driver cannot actually see the conditions of surrounding vehicles.
Furthermore, the existing digital LCD display interior rearview mirror is limited by the design of backlight brightness adjustment (on/off function), which causes severe light reflection in the external environment during daytime driving and easily causes unclear images; on the contrary, when the driver drives at night, the opening brightness of the display image is too bright, so that the driver feels tired and dazzling when watching the display image for a long time, and the driving safety of the driver is doubtful.

Detailed Description
Reference will now be made in detail to exemplary embodiments of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings and the description to refer to the same or like parts.
Fig. 1A is a schematic view of a rearview mirror with a display function according to an embodiment of the present invention. Fig. 1B to fig. 1D are schematic image frames of the rearview mirror of fig. 1A in different states. Referring to fig. 1A, in the present embodiment, a rearview mirror 100a with a display function includes a rearview mirror body 110 and a display structure layer 120 a. The display structure layer 120a is disposed on one side of the rearview mirror body 110 and includes a plurality of light emitting diodes 126a and a driving circuit layer 124 a. The light emitting diode 126a is disposed between the rearview mirror body 110 and the driving circuit layer 124a, and the light emitting diode 126a is electrically connected to the driving circuit layer 124 a. Here, the mirror 100a is, for example, an interior mirror.
In detail, in the present embodiment, the rearview mirror body 110 includes a substrate 112, a transparent electrode layer 114, a reflective electrode layer 116, a rubber frame 115, and an electrochromic material 118. The transparent electrode layer 114 is disposed on the substrate 112. The reflective electrode layer 116 is disposed on one side of the transparent electrode layer 114. The frame 115 is disposed between the transparent electrode layer 114 and the reflective electrode layer 116, wherein the frame 115, the transparent electrode layer 114 and the reflective electrode layer 116 define an accommodating space C. The electrochromic material 118 is filled in the accommodating space C. Here, the substrate 112 is, for example, a glass substrate, a plastic substrate, a laminate substrate, or the like, but not limited thereto.
More specifically, the transparent electrode layer 114 and the reflective electrode layer 116 are used to drive the electrochromic material 118. When the electrochromic material 118 is enabled (or intelligent) (e.g., when there is a sufficient potential difference between the transparent electrode layer 114 and the reflective electrode layer 116), the electrochromic material 118 undergoes an electrochemical redox reaction to change its energy level, and thus, assumes a dull (dim) state. At this time, when the external light (i.e., the incident light L1) sequentially passes through the substrate 112 and the transparent electrode layer 114 to reach the electrochromic material 118, the external light is absorbed by the electrochromic material 118, so that the rear-view mirror 100a is switched to the anti-glare mode. On the other hand, when the electrochromic material 118 is disabled (e.g., when there is no sufficient potential difference between the transparent electrode layer 114 and the reflective electrode layer 116), the electrochromic material 118 is in a transparent state, and at this time, the external light (i.e., the incident light L1) can sequentially pass through the substrate 112, the transparent electrode layer 114, and the electrochromic material 118 and be reflected by the reflective electrode layer 116 (i.e., form the reflected light L2), so that the rear-view mirror 100a is switched to the mirror mode. In other words, when the electrochromic material 118 is enabled, the ambient light beam from outside the display structure layer 120a is extinguished by the electrochromic material 118; when the electrochromic material 118 is disabled, an ambient light beam from outside the display structure layer 120a passes through the electrochromic material 118 and is reflected by the reflective electrode layer 116. Preferably, the electrochromic actuation principle is in a normal state, the transmittance of the initial state of the lens set is about 70-80%, and in an intelligent (enabled) state, the lens set applies an external voltage to change the color of the electrochromic material, and the transmittance can be reduced to below 40%.
In short, the incident light enters from the outside through the visible surface of the substrate 112, and the incident light L1 is reflected by the reflective electrode layer 116, so that the incident light L1 exits from the visible surface of the substrate 112. The reflection rate of the mirror body 110 to the incident light L1 is greater than 40%, and the transmittance of the mirror 100a to the image light is greater than 15%. In one embodiment, the shape of the visible surface is, for example, circular, elliptical, or polygonal. In another embodiment, the visible surface may be a full mirror. Furthermore, in an embodiment, the rearview mirror body may also include a housing, and the housing includes a sidewall surrounding a periphery of the substrate, and the sidewall has a front surface flush with a visible surface of the substrate. At this time, the surface shape of the visible surface may be, for example, a plane or a curved surface. In addition, the material of the transparent electrode layer 114 of the present embodiment is, for example, indium tin oxide, indium zinc oxide, aluminum tin oxide, aluminum zinc oxide, indium germanium zinc oxide, titanium oxide, or a composite material of at least two of the foregoing, and the material of the reflective electrode layer 116 is, for example, silver, copper, aluminum, titanium, nickel, chromium, molybdenum, or a composite material of at least two of the foregoing.
Referring to fig. 1A again, the display structure layer 120a of the present embodiment further includes a substrate 122 and a first planarization layer 123 a. The driving circuit layer 124a is disposed on the substrate 122 and located between the light emitting diode 126a and the substrate 122. The first planarization layer 123a is disposed on the light emitting diode 126a, and the light emitting diode 126a is disposed between the first planarization layer 123a and the driving circuit layer 124 a. Furthermore, the display structure layer 120a of the present embodiment further includes a color conversion layer 128 and a second flat layer 125 a. The color conversion layer 128 is disposed on the first planarization layer 123 a. The second flat layer 125a is disposed on the color conversion layer 128 and located between the rearview mirror body 110 and the color conversion layer 128. Here, the driving circuit layer 124a is, for example, an active device array circuit or a redistribution circuit layer. The leds 126a are, for example, a plurality of blue micro leds. The color conversion layer 128 is, for example, a phosphor layer or a quantum dot layer.
Since the led 126a has advantages of high brightness, high resolution, and no backlight source (self-luminescence), the display structure layer 120a of the present embodiment is not limited by the design of adjusting brightness of the backlight source (turning on/off function) and can improve the driving safety of the driver compared to the conventional digital LCD display interior mirror.
In the manufacturing process, the substrate 122 is provided. Then, a driving circuit layer 124a, an implanted light emitting diode 126a, a first planarization layer 123a, a screen printing color conversion layer 128, a second planarization layer 125a and a film-coated reflective electrode layer 116 are sequentially formed. Then, the sealant 115, the transparent electrode layer 114 and the substrate 112 are assembled, and the electrochromic material 118 is injected after baking, thereby completing the manufacturing of the rear view mirror 100 a. In short, the rearview mirror 100a with a display function of the present embodiment is embodied as an integrated structure.
In application, referring to fig. 1B, the rear view mirror 100a of the present embodiment can display a left image frame a1, a rear image frame a2 and a right image frame A3 by using a streaming media technique. Further, the left image screen a1 is an instantaneous image showing the outside left side mirror, and the right image screen A3 is an instantaneous image showing the outside right side mirror. Here, the back image screen a2 is located between the left image screen a1 and the right image screen A3, and the area of the back image screen a2 is larger than the area of the left image screen a1 and the area of the right image screen A3. That is, the rear view mirror 100a can simultaneously display three streaming media real-time image monitors, but not limited thereto. In another embodiment, the rear view mirror 100a may only display the rear image frame a 2.
Then, referring to fig. 1C, when the vehicle is to be switched to the left, the area of the left image frame a 1' may occupy more than 1/4 of the display frame a of the rear view mirror 100 a. That is, the left image screen a 1' can be enlarged to be more than 1/4 of the entire display screen a, so that the driver can clearly see the instantaneous image of the left side mirror outside the vehicle. At this time, the rearward image frame a 2' can be displayed in the display frame a at the same time for the driver to refer to.
Similarly, referring to FIG. 1D, when the vehicle is to be switched to the right, the area of the right image frame A3' can occupy more than 1/4 of the display frame A of the rear view mirror 100 a. That is, the right image screen a 3' can be enlarged to be more than 1/4 of the entire display screen a, so that the driver can clearly see the instantaneous image of the right side mirror outside the vehicle. At this time, the rearward image frame a 2' can be displayed in the display frame a at the same time for the driver to refer to.
In short, the present embodiment can combine the functions of the rearview mirror monitoring area, the blind spot auxiliary system, the driving photography and the like on the left and right sides of the exterior of the vehicle with the interior rearview mirror 100a by using the streaming media, and can display/switch three real-time monitoring images, so that when the driver changes lanes or turns during driving, the left image a1 or the right image A3 can be enlarged and lifted to be more than 1/4 of the display image a according to the requirement, thereby avoiding the blind spot of the sight, and further improving the safety of the driver.
More clearly, in the present embodiment, the advantages of the micro light emitting diode including high brightness, high resolution and no backlight source (self-luminescence) are utilized, and the streaming media is combined to the rearview mirror 100, so that 3 timely monitoring images can be displayed/switched, so that the driver can clearly see the state of the left side or the right side outside the vehicle when he/she wants to change lanes or turn during driving, and the safety of the driver can be improved. That is, in the present embodiment, the mirror image pickup lens frames (including Blind Spot) reminders) on the left and right sides of the vehicle exterior can be integrated into the interior mirror 100a, so as to achieve the purpose of monitoring the driving full view. It should be noted that the following embodiments follow the reference numerals and parts of the contents of the foregoing embodiments, wherein the same reference numerals are used to indicate the same or similar elements, and the description of the same technical contents is omitted.
